[0053] This embodiment discloses a method for repairing gas leakage of a gas-insulated switchgear, which is applied to a gas leakage repair platform. Figure 1 is a flow chart of a method for repairing gas leakage of a gas insulated switchgear disclosed in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0054] S110, scanning the gas insulated switchgear to locate the leakage location, and pre-processing the leakage location;

[0055] Gas Insulated Switchgear (GIS) refers to metal-enclosed switchgear that uses gas (usually SF6 gas) as the insulating medium in whole or in part. It mainly consists of circuit breakers, disconnectors, grounding switches, transformers (including current transformers and voltage transformers), lightning arresters, busbars, connectors and outgoing terminals. These devices or components are all enclosed in a metal grounded casing, which is filled with SF6 insulating gas at a certain pressure. Therefore, it is also called SF6 fully enclosed combination electrical appliances. Laser scanning or optical imaging can be used to locate the leaking part. The more mature methods of optical imaging are laser imaging and infrared imaging. Both use the infrared absorption characteristics of SF6 gas to make the leaking gas clearly visible in the field of vision and can be detected when the equipment is energized. An automated cleaning robot or a high-pressure water gun combined with a special cleaning agent can be used to deeply clean the leaking part, and mechanical or chemical methods can be used to thoroughly remove rust to ensure the cleanliness and roughness of the construction surface. The surface of the leaking point is subjected to necessary grinding, polishing or sandblasting to improve the bonding strength between the coating and the substrate. Depending on the requirements of the coating material, primer treatment can also be performed to enhance the adhesion and durability of the coating.

[0056] Optionally, scanning the gas insulated switchgear to locate the leakage location includes:

[0057] Transmitting a first laser signal through a laser scanning device, and receiving a second laser signal reflected from the gas-insulated switchgear;

[0058] Calculate the three-dimensional coordinates of each point on the surface of the gas-insulated switchgear in a preset coordinate system according to the directions and round-trip times of the first laser signal and the second laser signal;

[0059] The three-dimensional model of the gas-insulated switchgear is compared with the three-dimensional coordinates to determine the gas leakage location.

[0060] The laser scanning device transmits a first laser signal to the gas-insulated switchgear. The first laser signal is usually a pulsed laser beam with a specific wavelength and energy. The first laser signal precisely controls the rotation of the multi-faceted reflective prism through the built-in servo drive motor system, and quickly scans the surface of the gas-insulated switchgear along the horizontal and vertical axes. When the first laser signal is irradiated onto the surface of the gas-insulated switchgear, part of the laser will be reflected back to form a second laser signal. Parameters such as the intensity, direction, and round-trip time of the reflected signal are related to factors such as the material, shape, and air leakage of the surface of the gas-insulated switchgear. The laser scanning device receives the second laser signal reflected back from the gas-insulated switchgear. Through the built-in receiver or sensor, the received signal is converted into an electrical signal or a digital signal for subsequent processing and analysis. Using the principle of laser ranging, by measuring the round-trip time of the first laser signal and the second laser signal, the distance between the laser scanning device and each point on the surface of the gas-insulated switchgear can be calculated. At the same time, by measuring the horizontal and vertical values ​​of the laser beam, the position of each point on the surface of the gas-insulated switchgear in the preset coordinate system can be determined. According to the results of laser ranging and angle measurement, the three-dimensional coordinates of each point on the surface of the gas-insulated switchgear in the preset coordinate system can be calculated using a three-dimensional coordinate calculation algorithm. These coordinate data will be used for subsequent three-dimensional modeling and leakage location. Using three-dimensional modeling software or tools, a three-dimensional model of the gas-insulated switchgear is established based on information such as the structure, size, and material. The model should have a shape, size, and features similar to the actual gas-insulated switchgear for subsequent comparison and analysis. The calculated three-dimensional coordinates of each point on the surface of the gas-insulated switchgear are compared with the three-dimensional model. Through comparison and analysis, abnormal or deformed areas on the surface of the gas-insulated switchgear can be identified, which may be related to the leakage site. Based on the results of comparison and analysis, combined with the structure and leakage characteristics of the GIS equipment, the specific location and range of the leakage site can be determined.

[0061] By emitting a first laser signal through a laser scanning device and receiving a second laser signal reflected from a gas-insulated switchgear, the three-dimensional coordinates of each point on the surface of the device in a preset coordinate system can be accurately calculated according to the direction of the signal and the round-trip time. This method has high precision and can accurately reflect the slight changes on the surface of the device, thereby realizing the precise positioning of the leaking part. Laser scanning technology is a non-contact detection method that does not require direct contact with the surface of the device, avoiding errors or damage that may be caused by contact in traditional detection methods. At the same time, non-contact detection also improves detection efficiency and reduces human intervention in the detection process. By comparing the three-dimensional model of the gas-insulated switchgear with the three-dimensional coordinates obtained by laser scanning, a three-dimensional visualization image of the device can be generated. This image can intuitively display the structure of the device and the location of the leaking part, which is convenient for technicians to quickly analyze and judge. The precise location and three-dimensional visualization image provided by laser scanning technology provide strong support for repair work, shorten the repair time, and improve the repair efficiency. Laser scanning technology can realize the precise positioning and rapid repair of the leaking part, reducing the downtime and maintenance cost caused by equipment failure. At the same time, this technology can also improve detection efficiency, reduce detection costs, and thus reduce the overall maintenance cost of the equipment.

[0062] S120, determining a scheme for preparing a target interpenetrating network coating material according to the characteristics of the leaking part and the working environment, and coating the leaking part after pretreatment with the prepared target interpenetrating network coating material to form a target coating;

[0063] Leakage sites may be located at key locations such as welds, inflator nozzles, flange joints, and pressure gauges. These sites may leak due to long-term pressure, temperature changes, chemical corrosion, and other factors. GIS equipment usually operates in harsh environments such as high pressure, high temperature, and high humidity. Leakage sites may be exposed to corrosive gases, moisture, dust, and other pollutants. According to the characteristics of the leakage site and the working environment, select IPN coating materials with excellent corrosion resistance, high pressure resistance, high temperature resistance, and wear resistance. IPN (Interpenetrating Polymer Networks) coating materials, that is, interpenetrating network coating materials, are a special high-performance coating. IPN coating materials are formed by two or more polymer networks that penetrate, permeate, and interweave at the molecular level to form a blend system. This special structure enables IPN coating materials to have the advantages of each polymer component, thereby showing excellent performance. Common IPN coating materials include interpenetrating network polymers such as epoxy resins, polyurethanes, and acrylates. Determine the ratio and curing conditions of IPN coating materials according to the size, shape, and specific requirements of the working environment of the leakage site. During the preparation process, the proportion of each component, mixing uniformity and curing temperature and other parameters must be strictly controlled to ensure that the performance of the coating material is optimal. Use the prepared IPN coating material to evenly coat the leaking area. During the coating process, the thickness and uniformity of the coating must be controlled to ensure that the coating can completely cover the leaking area and form a dense protective layer. During the coating process, a non-contact thickness sensor is used to monitor the coating thickness in real time to ensure that the coating thickness meets the design requirements. According to the curing conditions of the coating material, appropriate heating or natural drying treatment is performed to promote the curing and cross-linking reaction of the coating.

[0064] Optionally, the scheme for determining the target interpenetrating network coating material according to the characteristics of the leakage location and the working environment includes:

[0065] Determine the material type and loss degree involved in the leakage part, and obtain the working environment information of the gas insulated switchgear, wherein the working environment information includes temperature range, humidity range, electrical strength, chemical corrosion and mechanical stress;

[0066] According to the material type, the loss degree and the working environment information, a match is performed in a preset material library to obtain a combination of a base polymer and a cross-linking agent, and an ultraviolet light stabilizer is added to the combination to form the solution.

[0067] The leaking part may be made of different materials, such as metal (stainless steel, aluminum alloy, etc.), ceramic, plastic, etc. Understanding the material type will help you choose the right coating material to ensure good bonding between the coating and the substrate. Evaluate the extent of the loss at the leaking part, including the amount of leakage, the rate of leakage, the size and shape of the leaking point, etc. When the amount of leakage is large, a thicker coating may be required to effectively seal the leaking point to ensure that the coating can provide adequate sealing. Smaller leaks may require a thinner coating, but it is still necessary to ensure good bonding between the coating and the substrate and adequate sealing performance. A fast leak rate indicates that the leaking point may be large or there is a high pressure difference, so it is necessary to choose a coating material that can cure quickly and has high strength and sealing performance. When the leak rate is slow, you can pay more attention to the durability and long-term stability of the coating. The size and shape of the leaking point will directly affect the selection and application of the coating. For example, for small holes or cracks, a coating material with better permeability may be required; for larger leaking areas, a thicker coating or a combination of multiple coatings may be required to ensure a sealing effect. The information of the leaking part (leakage volume, leakage rate, size and shape of the leaking point, etc.) as well as environmental conditions, mechanical stress, etc. can be input into the large model. The large model will calculate and simulate based on the input data and the performance database of the coating material to predict the sealing effect and long-term stability of the leaking part under different coating thicknesses and performance requirements. The large model outputs the optimal coating thickness and performance requirement recommendations. Understand the operating temperature range of the GIS equipment and its leaking parts, including the maximum and minimum operating temperatures. This helps to select coating materials that can withstand these temperature changes. GIS equipment may operate in a high humidity environment, so the coating material should have good moisture resistance. GIS equipment is a high-voltage device, and the coating material should have good electrical insulation properties to prevent electrical breakdown or discharge. GIS equipment may be exposed to corrosive gases or chemicals, so the coating material should have good corrosion resistance. The leaking part may be subjected to mechanical stress, such as vibration, impact, etc. The coating material should have a certain elastic modulus and tear strength to withstand these mechanical stresses. The elastic modulus and tear strength of the coating material can be measured using standard material testing methods. For example, tensile tests can be used to measure elastic modulus, and tear tests can be used to measure tear resistance. Based on the test results, coating materials with sufficient elastic modulus and tear resistance are selected. These materials should be able to maintain integrity and sealing effect when mechanical stress is applied to the leaking part. In addition to immediate performance, the durability of the coating material's performance also needs to be considered. For example, the coating material should be able to maintain its elasticity and tear resistance under long-term mechanical stress without aging or cracking.

[0068] Preset material library: Establish a preset material library containing a variety of base polymers and cross-linkers. These materials should have different performance characteristics, such as corrosion resistance, high temperature resistance, wear resistance, etc. Match in the preset material library according to the material type, loss degree and working environment information of the leaking part. Select a base polymer and cross-linker combination that has good compatibility with the material of the leaking part and can meet the requirements of the working environment. UV stabilizers can absorb or reflect ultraviolet rays to prevent the coating material from aging and degradation due to ultraviolet radiation. Add an appropriate amount of UV stabilizer to the selected base polymer and cross-linker combination. Ensure that the UV stabilizer is compatible with the base polymer and cross-linker and does not affect the overall performance of the coating. Adjust the amount of UV stabilizer added according to the thickness of the coating and the intensity of ultraviolet rays in the working environment.

[0069] By accurately analyzing the material type and loss degree involved in the leakage part, the compatibility and adhesion of the selected coating material with the substrate can be ensured, while taking into account the requirements of the loss degree for the coating thickness and performance. Obtain information on the working environment of the gas-insulated switchgear, including temperature range, humidity range, electrical strength, chemical corrosiveness, and mechanical stress, which directly affect the selection and service life of the coating material. By comprehensively considering these factors, it can be ensured that the selected coating material has sufficient weather resistance, corrosion resistance, and mechanical strength to meet the requirements of the actual working environment. Matching is performed in the preset material library to obtain a combination of base polymers and crosslinkers that are suitable for the material type and working environment of the leakage part. This combination ensures that the coating material has excellent physical properties and chemical stability, while improving the crosslinking density and weather resistance of the coating. For leakage parts that may be exposed to ultraviolet light, adding ultraviolet light stabilizers can significantly improve the anti-aging properties of the coating and extend the service life of the coating. By selecting a suitable combination of base polymers and crosslinkers and adding necessary additives, the corrosion resistance of the coating can be significantly improved, effectively resisting the erosion of chemical corrosion and electrochemical corrosion. In view of the high voltage environment of gas insulated switchgear, the selected coating material should have good electrical insulation performance. By optimizing the material combination and formulation, it is possible to ensure that the coating has stable electrical strength under high voltage environment to prevent electrical breakdown and leakage. In view of the mechanical stress that may be exerted on the leakage part, the selected coating material should have sufficient strength and toughness to withstand mechanical stress such as vibration, impact and extrusion during the operation of the equipment. By presetting the material library and matching algorithm, the preparation process of coating materials can be simplified and the construction efficiency can be improved. Through precise material matching and formulation optimization, the performance of coating materials can be ensured to be stable and reliable, thereby improving the construction quality.

[0070] Optionally, matching in a preset material library according to the material type, the loss degree and the working environment information to obtain a combination of a base polymer and a cross-linking agent includes:

[0071] Screening out a first base polymer candidate set from a preset material library according to the material type, the first base polymer candidate set having a compatibility with the material type better than a preset standard;

[0072] Determine the required strength and toughness according to the loss degree, and select a second base polymer candidate set that meets the strength and toughness from the first base polymer candidate set;

[0073] Selecting a base polymer from the second base polymer candidate set according to the working environment information, and selecting a cross-linking agent set having a compatibility with the base polymer better than a preset standard from the preset material library;

[0074] According to the repair requirements, a cross-linking agent is selected from the cross-linking agent set, and the ratio of the base polymer and the cross-linking agent is determined.

[0075] Accurately identify the material type involved in the leak, such as metal (such as stainless steel, aluminum alloy, etc.), plastic (such as epoxy resin, polytetrafluoroethylene, etc.) or other composite materials. Query the preset material library for base polymers that are more compatible with the identified material type than the preset standard. The preset material library is a database containing a variety of base polymers and their compatibility data with different materials. According to the query results, filter out the preset number of base polymers that are more compatible with the material type than the preset standard to form a first base polymer candidate set. Evaluate the degree of loss of the leak, including the size, shape, depth of the leak, and whether it is accompanied by cracks, corrosion, etc. Determine the required coating strength and toughness based on the evaluation results of the degree of loss. Quantify the size of the leak by measuring the diameter, area or volume of the leak point. Large leaks may require thicker coatings or special coating materials to ensure the sealing effect. The shape of the leak may be round, oval, crack-shaped or other irregular shapes. The irregularity of the shape may affect the coating and sealing effect of the coating, and it is necessary to select a coating material that can adapt to these shapes. The depth of the leak point may affect the adhesion and sealing performance of the coating. Deeper leaks may require multiple layers of coating or special coating techniques to ensure a complete seal. Check if the leak is accompanied by cracks, corrosion or other damage. Cracks and corrosion may reduce the adhesion and sealing performance of the coating, and it is necessary to select a coating material with higher strength and corrosion resistance. Determine the required coating strength based on the mechanical stress (such as vibration, impact, etc.) and working environment (such as temperature, humidity, etc.) to which the leak is subjected. High-strength coatings can better resist mechanical stress and environmental corrosion, thereby extending the life of the leak. Toughness refers to the ability of a coating to absorb energy and maintain integrity when subjected to external forces. For leaks that may be subjected to vibration or impact, it is necessary to select a coating material with higher toughness. Input the size, shape, depth of the leak, and whether it is accompanied by cracks, corrosion, etc. into the trained large model. At the same time, input the mechanical stress, working environment, and other conditions to which the leak is subjected. The large model performs complex calculations and simulations based on the input data. Consider the performance parameters of the coating material (such as strength, toughness, corrosion resistance, etc.) and the coating process (such as coating thickness, coating method, etc.). Output the optimal coating solution, including the selection of coating materials, determination of coating thickness, and recommendations for coating processes. Strength and toughness are key indicators for coating materials to resist external force damage and maintain integrity. In the first base polymer candidate set, base polymers that meet these requirements are screened out based on the requirements for strength and toughness to form a second base polymer candidate set. Analyze the working environment information of the gas-insulated switchgear, including temperature range, humidity range, electrical strength, chemical corrosion, and mechanical stress. In the second base polymer candidate set, select the most suitable base polymer based on the requirements of the working environment information.This base polymer should have good weather resistance, corrosion resistance and mechanical strength to adapt to changes in the working environment. Select a set of crosslinkers from the preset material library that have better compatibility with the selected base polymer than the preset standard. The crosslinker is the key component that enables the base polymer to form an interpenetrating network structure, which has an important impact on the performance of the coating. A detailed analysis is conducted on the repair requirements of the leaking part, including the service life after repair, performance requirements, and construction conditions. From the crosslinker set, the most suitable crosslinker is selected according to the repair requirements. This crosslinker should have good compatibility with the selected base polymer and can form a stable interpenetrating network structure. Finally, according to the characteristics of the selected base polymer and crosslinker, as well as the repair requirements, their ratio is determined. This ratio should ensure that the coating has excellent physical properties and chemical stability while meeting the requirements of construction conditions. The trained large model is used to simulate and evaluate the compatibility of the candidate crosslinker with the base polymer. This includes considering factors such as the interaction between the crosslinker and the base polymer molecular chain, the formation of chemical bonds, and the ability to form an interpenetrating network structure. Select a crosslinker that can form a stable interpenetrating network structure. The interpenetrating network structure can enhance the physical properties and chemical stability of the coating. The large model can simulate the interaction and distribution of the crosslinker and the base polymer in the interpenetrating network structure, so as to evaluate its formation ability. The crosslinker is further screened according to the specific repair requirements (such as coating strength, toughness, corrosion resistance, temperature resistance, etc.). The large model can select the most suitable crosslinker based on the repair requirements and comprehensively consider the various performance indicators of the crosslinker. The large model is used to simulate and calculate the ratio of the crosslinker to the base polymer. Consider the performance changes of the coating under different ratios, including strength, toughness, corrosion resistance, temperature resistance, etc. Through the optimization algorithm, the optimal ratio scheme is found to ensure that the coating has excellent physical properties and chemical stability. When determining the ratio, it is also necessary to consider the requirements of the construction conditions, such as curing time, temperature, humidity, etc. The large model can simulate the curing process and performance changes of the coating under different construction conditions, so as to ensure that the ratio scheme can meet the requirements of the construction conditions.

[0076] By selecting a first base polymer candidate set from a preset material library with compatibility with the material type better than the preset standard according to the material type, it can be ensured that the selected base polymer has good compatibility and adhesion with the material of the leaking part, thereby improving the overall performance of the coating. Determine the required strength and toughness according to the degree of loss, and select a second base polymer candidate set that meets the requirements from the first base polymer candidate set, so as to ensure that the coating has sufficient strength and toughness to resist various mechanical stresses and chemical corrosion during the operation of the equipment, thereby improving the durability and service life of the coating. Select a base polymer from the second base polymer candidate set according to the working environment information (such as temperature range, humidity range, electrical strength, chemical corrosion, etc.), so as to ensure that the selected base polymer can adapt to various conditions of the actual working environment and has excellent weather resistance, corrosion resistance and electrical insulation properties. Select a cross-linking agent set from the preset material library with compatibility with the selected base polymer better than the preset standard, so as to ensure that a good interpenetrating network structure can be formed between the cross-linking agent and the base polymer, thereby improving the cross-linking density and overall performance of the coating. Select a cross-linking agent from the cross-linking agent set according to the repair requirements, and determine the ratio of the base polymer and the cross-linking agent, so as to further optimize the performance of the coating. By adjusting the ratio, the hardness, flexibility, corrosion resistance, electrical insulation and other aspects of the coating can be balanced to meet specific repair needs. Through precise matching and screening, adaptability to the working environment and ratio optimization, the coating material can be customized to meet the specific needs of different leaking locations and working environments. This customized design can significantly improve the performance and service life of the coating while reducing repair and maintenance costs.

[0077] S130, determining curing parameters according to the type and thickness of the interpenetrating network coating material and the working environment, determining the power of the heating source according to the curing parameters, and curing the target coating by the heating source based on the power of the heating source, wherein the curing parameters include curing time, temperature, humidity and air pressure;

[0078] The type of coating (such as different IPN combinations, types of base polymers and crosslinkers) and thickness are key factors affecting the curing process. Different coating materials may have different requirements for curing conditions such as temperature, humidity, and air pressure. The thicker the coating, the longer the curing time and the higher the temperature may be required to ensure that the coating is fully crosslinked and cured. The working environment includes the environmental conditions such as temperature, humidity, and air pressure in which the coating is cured. These factors will affect the curing speed and curing quality of the coating. For example, in a high humidity environment, the coating may absorb moisture more easily, which will affect its curing effect and performance. Based on the determined curing parameters (curing time, temperature, humidity, and air pressure), the required heating source power can be calculated. The setting of the heating source power needs to ensure that the coating can reach the required curing temperature within the specified curing time while maintaining the appropriate humidity and air pressure conditions. The setting of the heating source power also needs to consider the heating efficiency to avoid overheating or underheating caused by curing quality problems. Determine the heat demand during the curing process: This includes the energy required to heat the material to the required temperature and the energy required to maintain that temperature until the curing is complete. Consider heating efficiency: The efficiency of heat transfer from the heating source to the material can be affected by many factors, such as the heating method, material properties, environmental conditions, etc. Calculate the power of the heating source: Based on the heat demand and heating efficiency, calculate the required power of the heating source. Specifically, calculate the energy required to heat up: Use the formula Q=mcΔT, where Q is the energy required to heat up, m is the mass of the material, c is the specific heat capacity of the material, and ΔT is the change in temperature (i.e., the difference between the required temperature and the initial temperature). Calculate the energy required to maintain the temperature: This usually involves an estimate of heat losses, including heat lost through conduction, convection, and radiation. This energy can be estimated using a heat balance equation or an empirical formula. The heating efficiency depends on the type of heating source, the thermal conductivity of the material, and environmental conditions (such as humidity and air pressure, which may affect convection and radiation heat dissipation). Calculate the power of the heating source: Add the energy required to heat up and the energy required to maintain the temperature to get the total heat demand. Divide the total heat demand by the curing time (taking into account the heating efficiency and possible heat losses) to get the required power of the heating source. Humidity and air pressure affect heating efficiency mainly by affecting convection and radiation heat dissipation. Under high humidity or low air pressure conditions, it may be necessary to increase the power of the heating source to compensate for the increase in heat dissipation. Different heating methods (such as microwave heating, resistance heating, induction heating, etc.) have different heating efficiencies and applicable ranges. When choosing a heating method, factors such as material properties, heating efficiency, and cost need to be considered. With the set heating source power, the target coating is heated and cured using a heating source (such as a hot air gun, heating plate, oven, etc.). During the curing process, parameters such as temperature, humidity, and air pressure of the coating need to be continuously monitored to ensure that they remain within the specified range. After curing is completed, the coating needs to be cooled and inspected to ensure that it meets performance requirements.

[0079] Optionally, determining the curing parameters according to the type and thickness of the interpenetrating network coating material and the working environment includes:

[0080] Determining the basic curing time and basic curing temperature under basic thickness and basic working environment according to the type of the interpenetrating network coating material;

[0081] Determine a first adjustment to the basic curing time according to a first difference between the thickness and the basic thickness, and determine a second adjustment to the basic curing time according to a second difference between the working environment and the basic working environment;

[0082] The basic curing time is adjusted according to the first adjustment and the second adjustment to obtain a final curing time.

[0083] According to the type of interpenetrating network coating material (such as different base polymers, cross-linking agent types and their combinations), determine the basic curing time and basic curing temperature under the basic thickness (usually the standard or recommended thickness of this type of coating material) and the basic working environment (usually the standard or recommended working environment of this type of coating material). The basic thickness can be determined based on the reference thickness given by the manufacturer of the gas-insulated switchgear. The basic curing time is first adjusted according to the difference between the actual coating thickness and the basic thickness (the first difference). Generally, the thicker the coating, the longer the curing time is required because it is necessary to ensure that the inside of the coating is also fully cured. Therefore, if the actual coating thickness is greater than the basic thickness, the curing time may need to be increased; conversely, if the actual coating thickness is less than the basic thickness, the curing time may need to be reduced. The adjusted curing time can be estimated based on the first difference by referring to the curve or table of curing time versus thickness provided by the coating material supplier. The basic curing time is second adjusted based on the difference between the actual working environment and the basic working environment (the second difference). Differences in working environment, such as temperature, humidity, air pressure, etc., will affect the curing speed and curing quality of the coating. For example, at higher temperatures, the coating will generally cure faster, so the curing time may need to be reduced; at lower humidity, the coating may be easier to dry and cure, so the curing time may also need to be reduced. However, it should be noted that these adjustments need to be considered comprehensively because there may be interactions between different factors. A trained large model (such as a prediction model based on machine learning) can be used to predict the curing time of the coating under different working environment conditions. These large models are usually trained by analyzing a large amount of historical data and experimental data, and can accurately reflect the impact of the working environment on the curing time. According to the model prediction results, the basic curing time is adjusted. If the actual working environment conditions are more conducive to the curing of the coating (such as higher temperature and lower humidity), the curing time can be appropriately reduced; otherwise, the curing time needs to be increased. After the above first adjustment and second adjustment, the two adjusted curing times are considered comprehensively to obtain the final curing time. More advanced large models (such as deep learning models or integrated learning models) can be used to comprehensively consider multiple factors and predict the final curing time. These models can handle more complex data and relationships and give more accurate prediction results. When training these models, a large amount of historical data and experimental data can be used to enhance the prediction ability of the model. When adjusting the curing time, the interaction between different factors needs to be carefully managed to ensure that the adjusted curing time can ensure that the coating is fully cured without causing overheating or under-curing. In addition, factors such as the thermal sensitivity of the coating and the heating efficiency need to be considered to avoid unnecessary thermal stress or thermal damage during the curing process.

[0084] The basic curing time and basic curing temperature at the basic thickness and basic working environment are determined according to the type of interpenetrating network coating material. This provides a reliable starting point for subsequent adjustments and ensures that the setting of curing parameters is based on material properties. The first adjustment and the second adjustment of the basic curing time are made by considering the difference between the coating thickness and the basic thickness (the first difference) and the difference between the working environment and the basic working environment (the second difference). This adjustment method takes into account the differences in the actual coating thickness and the working environment, making the setting of the curing time more accurate and better adapted to different coating conditions. Through the first adjustment, flexible curing time settings can be made for coatings of different thicknesses. Thicker coatings require longer curing times to ensure sufficient internal cross-linking, while thinner coatings may require shorter curing times to avoid overheating. Through the second adjustment, the curing time can be adjusted for different working environments. For example, in a higher temperature environment, the curing time may need to be shortened to avoid overheating of the coating; while in a lower temperature environment, the curing time may need to be extended to ensure sufficient curing of the coating. Through the precise adjustment process, the error of the curing time can be reduced, thereby ensuring that the coating reaches the required degree of curing within the specified time. This helps to improve production efficiency and reduce coating quality problems caused by improper curing time. Accurate curing parameter settings help optimize the curing process so that the coating can maintain stable performance and quality during the curing process. This helps reduce production costs and improve the overall competitiveness of the product.

[0085] Optionally, determining the heating source power according to the curing parameters includes:

[0086] Calculating the volume of the target coating according to the thickness and area of ​​the target coating, and calculating the total heat capacity of the target coating according to the density, specific heat capacity and volume of the interpenetrating network coating material;

[0087] The required heating source power is determined according to the total heat capacity, the difference between the basic curing temperature and the room temperature, the heating efficiency of the heating source, and the final curing time.

[0088] Obtain the thickness and area data of the target coating. These data can be obtained through measurement or design documents. Use the volume calculation formula (volume = area × thickness) to calculate the volume of the target coating. Obtain the density and specific heat capacity of the interpenetrating network coating material. These data can usually be found in the technical documentation of the material or the information provided by the manufacturer. Use the total heat capacity calculation formula (total heat capacity = mass × specific heat capacity, and mass = density × volume) to calculate the total heat capacity of the target coating. Substitute the previously calculated volume and the known density and specific heat capacity into the formula to obtain the total heat capacity of the target coating. The base cure temperature is the basic temperature required for the coating to reach full cure. This temperature is usually determined based on the material properties of the coating and the curing requirements. The heating efficiency of the heating source refers to the efficiency of the heating source in converting electrical energy or other forms of energy into thermal energy. This efficiency can usually be found in the technical documentation of the heating source or the information provided by the manufacturer. Use a variation of the power calculation formula (power × time × heating efficiency = heating energy required) to calculate the required heating source power. Here, the heating energy required can be regarded as the sum of the total heat capacity of the target coating and the amount of heat required from room temperature to the base cure temperature (i.e., total heat capacity × temperature change). Substituting the total heat capacity, the difference between the basic curing temperature and the room temperature (i.e., the temperature change), the heating efficiency of the heating source, and the final curing time into the formula, the required heating source power can be obtained. However, it should be noted that due to the possible heat loss during the heating process, the actual required heating source power may need to be appropriately increased to compensate for these losses. In practical applications, it is also necessary to consider the effects of factors such as the uniformity of the heating source, the thermal conductivity of the coating material, and the heat loss of the heating environment on the heating source power. These factors may cause the actual required heating source power to differ from the theoretical calculated value.

[0089] By calculating the volume of the target coating and combining the density and specific heat capacity of the interpenetrating network coating material, the total heat capacity of the target coating can be accurately calculated. This is one of the key parameters for determining the power of the heating source, as it determines how much heat the heating source needs to provide to bring the coating to the desired curing temperature. Based on the heat capacity of the target coating, the base curing temperature, the heating efficiency of the heating source, and the final curing time, the required heating source power can be accurately calculated. This accuracy ensures that the coating can reach the required curing temperature within the specified time while avoiding quality problems caused by overheating or under-curing. Accurate heating source power setting can optimize the heating process so that the heating source can provide the required heat with minimal energy consumption. This helps to reduce production costs and improve production efficiency. With accurate heating source power setting, it can be ensured that the coating reaches the required curing temperature in a short time, thereby shortening the curing time. This helps to increase the throughput of the production line and speed up product delivery. Accurate heating source power setting ensures that the coating maintains a stable temperature and performance during the curing process, thereby avoiding quality problems caused by insufficient curing or overheating. This helps to improve the reliability and service life of the product.

[0090] Optionally, the method further includes:

[0091] Collecting the actual temperature of the target coating, and determining whether the difference between the actual temperature and the basic curing temperature is greater than a threshold;

[0092] When the difference between the actual temperature and the basic curing temperature is greater than a threshold and the actual temperature is greater than the basic curing temperature, the power of the heating source is reduced according to a preset ratio according to a third difference between the actual temperature and the basic curing temperature;

[0093] When the difference between the actual temperature and the basic curing temperature is greater than a threshold and the actual temperature is lower than the basic curing temperature, the power of the heating source is increased according to a preset ratio based on a fourth difference between the basic curing temperature and the actual temperature.

[0094] During the coating curing process, the actual temperature near the target coating is collected in real time through temperature sensors and other equipment. This requires ensuring that the temperature sensor can accurately and quickly reflect the temperature status of the coating. The collected actual temperature is compared with the preset basic curing temperature to calculate the difference between the two. A threshold is set to determine whether the difference between the actual temperature and the basic curing temperature is too large, so as to determine whether the power of the heating source needs to be adjusted. When the difference between the actual temperature and the basic curing temperature is greater than the threshold, and the actual temperature is greater than the basic curing temperature, it means that the coating temperature is too high and the power of the heating source needs to be reduced to prevent overheating. According to the third difference between the actual temperature and the basic curing temperature (that is, the part where the actual temperature is higher than the basic curing temperature), the power of the heating source is lowered according to the preset ratio. The preset ratio should be reasonably set according to factors such as the material properties and thickness of the coating and the heating efficiency of the heating source to ensure that the adjusted power can quickly reduce the coating temperature to a level close to the basic curing temperature. When the difference between the actual temperature and the basic curing temperature is greater than the threshold, and the actual temperature is less than the basic curing temperature, it means that the coating temperature is too low and the power of the heating source needs to be increased to accelerate curing. According to the fourth difference between the basic curing temperature and the actual temperature (i.e., the part where the basic curing temperature is higher than the actual temperature), the power of the heating source is increased according to the preset ratio. Similarly, the preset ratio should be set reasonably to ensure that the adjusted power can quickly raise the coating temperature to a level close to the basic curing temperature. After adjusting the power of the heating source, the actual temperature of the coating should be continuously monitored to evaluate the effect of the adjustment. If the adjusted temperature still deviates greatly from the basic curing temperature, it may be necessary to further adjust the power of the heating source or check whether equipment such as the temperature sensor is working properly. Through continuous monitoring and feedback, the adjustment strategy of the heating source power can be gradually optimized to ensure that the coating maintains a stable temperature during the curing process.

[0095] By collecting the actual temperature of the target coating, the heating state of the coating can be understood in real time, providing accurate data support for subsequent power adjustment. By judging whether the difference between the actual temperature and the basic curing temperature is greater than the threshold, it can be timely discovered whether the coating temperature deviates from the expected curing temperature range. When the difference between the actual temperature and the basic curing temperature is greater than the threshold, the power of the heating source is dynamically adjusted according to the preset ratio based on the size and direction of the difference. This adjustment mechanism can ensure that the coating temperature is always kept within an appropriate range, thereby improving the accuracy and stability of curing. When the actual temperature is higher than the basic curing temperature and the difference is greater than the threshold, lowering the power of the heating source can avoid overheating of the coating, thereby reducing unnecessary energy consumption and coating damage. When the actual temperature is lower than the basic curing temperature and the difference is greater than the threshold, increasing the power of the heating source can accelerate the heating process of the coating, shorten the curing time, and improve production efficiency. Through precise temperature control and power adjustment, curing defects such as cracks and bubbles caused by temperature fluctuations can be reduced, thereby improving the overall quality of the coating. Stable curing temperature and appropriate power of the heating source can ensure that the polymer molecules inside the coating are fully cross-linked, thereby improving the hardness, wear resistance, corrosion resistance and other properties of the coating.

[0097] Select appropriate leak detection equipment, such as pressure decay tester, helium mass spectrometer leak detector, ultrasonic leak detector, etc. The selection of equipment should be determined according to the characteristics of the leaking part, the repair material and the working environment.

Before conducting a leak test, confirm that the coating has been completely cured. Seal the leaking part and its surroundings to form a closed test area. Use appropriate inflation equipment to fill a certain amount of gas (such as nitrogen, helium, etc.) into the closed test area and pressurize it to a preset value. The inflation pressure and time should be determined according to the requirements of the leak detection equipment. Start the leak detection equipment and perform a leak test on the closed test area. Record the data during the test, such as the leak rate, leak location, etc. For suspected leak points, further confirmation and positioning should be carried out. Evaluate the repair effect based on the leak detection results.
