[0002] Distributed photovoltaic power stations are mainly divided into two forms: building-attached photovoltaics (BAPV) and building-integrated photovoltaics (BIPV). BAPV refers to the installation of photovoltaic modules on existing buildings, especially rooftop applications. This form of photovoltaic modules needs to meet two key requirements: one is light weight to reduce the load on the original building; the other is rich appearance colors to meet the needs of architectural aesthetics and the development of the times.

[0003] However, existing BAPV photovoltaic products have the following main problems:

[0004] 1. Single color appearance: The appearance of traditional BAPV modules is that the cells can be seen, the color of the cells is shown in the middle, and the edges are transparent glass. This kind of BAPV module without glaze has a single color in actual application and is difficult to match with the architectural style or the development needs of the times.

[0005] 2. Glare problem: Currently, most BAPV modules use ultra-clear float glass or rolled glass, which will produce obvious reflection and glare in the sun, seriously affecting the normal life of people and animals, especially in urban environments.

As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0050] It should also be understood that the term “and / or” used in the specification and appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0051] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0052] With the continuous advancement of the dual-carbon policy, the construction of distributed photovoltaic power stations has become an important means to achieve green energy and sustainable development. Distributed photovoltaic power stations are mainly divided into two forms: building-attached photovoltaics (BAPV) and building-integrated photovoltaics (BIPV). BAPV refers to the installation of photovoltaic modules on existing buildings, especially roof applications. This form of photovoltaic modules needs to meet two key requirements: one is light weight to reduce the load on the original building; the other is rich appearance colors to meet the needs of architectural aesthetics and the development of the times.

[0053] However, existing BAPV photovoltaic products have the following main problems:

[0054] 1. Single color appearance: The appearance of traditional BAPV modules is that the cells can be seen, the color of the cells is shown in the middle, and the edges are transparent glass. This kind of BAPV module without glaze has a single color in actual application and is difficult to match with the architectural style or the development needs of the times.

[0055] 2. Glare problem: Currently, most BAPV modules use ultra-clear float glass or rolled glass, which will produce obvious reflection and glare in the sun, seriously affecting the normal life of people and animals, especially in urban environments.

[0056] Therefore, there is an urgent need for a high-temperature colored glaze glass tempering method to produce colored glaze glass with rich colors and low glare, so as to solve at least one of the above problems.

[0057] See also Figure 1 , Figure 1 It is a schematic flow chart of the steps of a method for tempering high-temperature colored glaze glass provided in one embodiment of the present application.

[0058] Specifically, Figure 1 As shown, the provided method for tempering high temperature colored enamel glass includes steps S101 to S106. The details are as follows:

[0059] Step S101. Provide colored glaze glass to be tempered, wherein the thickness of the colored glaze glass is less than a preset thickness.

[0060] Specifically, by selecting colored glaze glass suitable for tempering, its thickness must be less than a preset value. This preset value is usually determined by factors such as the processing capacity of the tempering furnace and the thermal expansion coefficient of the colored glaze glass. Colored glaze glass is usually formed by coating one or more layers of colored glaze on the glass surface by screen printing or other methods, and then sintering at high temperature.

[0061] For example, the preset thickness may be 4 mm, which means that the thickness of all the colored glaze glasses to be tempered should be less than 4 mm. Common colored glaze glass thicknesses include 2 mm, 3 mm, 3.2 mm, etc.

[0062] By choosing the right thickness of enameled glass you can ensure that the glass will not crack due to excessive temperature changes during the tempering process. Thinner glass is easier to heat and cool evenly, resulting in better tempering results.

[0063] Step S102: Obtaining tempering parameters corresponding to the colored glaze glass according to the thickness of the colored glaze glass; the tempering parameters at least include tempering temperature, tempering time and tempering speed.

[0064] Specifically, the optimal parameters of the colored glaze glass of different thicknesses during the tempering process are determined through experimental data or pre-established models. The tempering parameters include tempering temperature, tempering time, and tempering speed, etc. These parameters have a direct impact on the quality of the final colored glaze glass.

[0065] For example, for 3mm thick enameled glass, the tempering temperature may be set to 680°C, the tempering time may be set to 3 minutes, and the tempering speed may be set to 0.5m / min. For 3.2mm thick enameled glass, the tempering temperature may be set to 700°C, the tempering time may be set to 4 minutes, and the tempering speed may be set to 0.4m / min.

[0066] By optimizing the parameters of the tempering process for glass of different thicknesses, energy consumption and production costs can be reduced, ensuring that each piece of enameled glass can achieve the best tempering effect and improving product quality and consistency.

[0067] Step S103: introducing sulfur dioxide gas into the ceramic roller of the tempering furnace to form a protective film on the surface of the ceramic roller.

[0068] Specifically, a protective film is formed on the surface of the ceramic roller by introducing sulfur dioxide gas. The main function of the protective film is to prevent the colored glaze glass from directly contacting the ceramic roller during the tempering process, thereby reducing friction and scratches, and preventing the glaze layer from peeling off. For example, the time for introducing sulfur dioxide gas can be set to 10-20 minutes, and the gas flow rate can be between 1-2m³ / h. The thickness of the protective film can be controlled between 0.1-0.5μm. The protective film can significantly reduce the surface damage of the colored glaze glass during the tempering process. Prevent the colored glaze layer from peeling off due to friction at high temperature, and improve the aesthetics and durability of the product.

[0069] Step S104: providing a plurality of pieces of drilled glass.

[0070] Specifically, prepare multiple pieces of pre-drilled glass, which will be used to absorb excess sulfur dioxide gas in the next step. The number and aperture of the drilled glass need to be optimized according to the size of the tempering furnace and the adsorption capacity of sulfur dioxide gas. For example, the thickness of the drilled glass can be 4mm and the aperture can be 10-20mm. For example, 10-20 pieces of drilled glass can be prepared. The drilled glass can effectively absorb excess sulfur dioxide gas and reduce its impact on the subsequent tempering process. Ensure that the protective film on the ceramic roller is uniform and stable, and improve the tempering quality of the glazed glass.

[0071] Step S105: tempering the preset number of drilled glasses in the ceramic roller to absorb the excess sulfur dioxide gas when the protective film is formed in the furnace body.

[0072] Specifically, the drilled glass is placed on a ceramic roller and the excess sulfur dioxide gas is adsorbed through a high temperature tempering process. The number and placement of the drilled glass need to match the tempering parameters to ensure the adsorption effect. For example, 10 pieces of drilled glass are placed on a ceramic roller and subjected to high temperature treatment for 5-10 minutes. The tempering temperature can be set to 650-700°C.

[0073] By effectively removing excess sulfur dioxide gas, it can avoid its negative impact on the tempering process of colored glaze glass, ensure that the protective film of the ceramic roller is not polluted, and improve its service life and tempering effect.

[0074] Step S106. After the adsorption of sulfur dioxide gas is completed, the colored glaze glass is tempered in the ceramic roller according to the tempering parameters to obtain the tempered colored glaze glass.

[0075] Specifically, after the drilled glass absorbs excess sulfur dioxide gas, the colored glaze glass is placed in a ceramic roller and tempered according to the optimized tempering parameters. The tempering process includes heating, quenching and other steps to ensure that the colored glaze glass reaches the required tempering strength and performance.

[0076] For example, the optimized colored glaze glass is placed in a ceramic roller and tempered according to the temperature (e.g., 680°C), time, and speed (e.g., 3 minutes, 0.5 m / min) determined in step S102. The stability and consistency of the tempering process are ensured through real-time monitoring.

[0077] By optimizing the tempering parameters, the best tempering effect of the colored glaze glass is ensured, and its strength and durability are improved. The aesthetics and functionality of the colored glaze glass are further improved to meet the needs of architectural design and aesthetics. Through the above steps, the shortcomings of the existing BAPV photovoltaic products in terms of single color and glare problems can be effectively solved, and the tempering quality and production efficiency of the colored glaze glass can be improved.

[0078] In some embodiments, the preset thickness is 2 mm.

[0079] By choosing 2mm thick enameled glass as the material to be tempered. 2mm thick enameled glass is easier to heat and cool evenly during the tempering process, thus achieving better tempering results. For example, choose 2mm thick enameled glass with a size of 1.5m x1m. This thickness of enameled glass is commonly found in some light-weight construction or decorative applications, such as curtain walls, interior partitions, etc. 2mm thick enameled glass is not prone to uneven internal stress during the tempering process, thus reducing the risk of cracking and deformation. By reducing the thickness of the glass, the production efficiency of the tempering furnace can be improved and energy consumption can be reduced. It is suitable for architectural applications that require high-strength and lightweight enameled glass.

[0080] In some embodiments, the tempering temperature corresponds to a temperature range of 680 to 720° C., the tempering time corresponds to a time range of 60 to 140 s, and the tempering speed corresponds to a speed range of 300 to 500 inches / minute.

[0081] According to the specific thickness of the colored enameled glass, the range of tempering temperature, tempering time and tempering speed is selected to ensure the best tempering effect. The temperature range of 680 to 720℃ is suitable for the tempering treatment of most colored enameled glass, ensuring that the glass is fully softened and evenly heated. The tempering time range of 60 to 140 seconds can be adjusted according to the glass thickness and the heating efficiency of the tempering furnace to ensure that the glass is kept at high temperature for a sufficient time. The tempering speed range of 300 to 500 inches / minute is suitable for the continuous production of large-sized colored enameled glass, ensuring the uniformity of the heating and cooling processes.

[0082] For example, for 3mm thick enameled glass, the tempering temperature can be 700℃, the tempering time can be 100 seconds, and the tempering speed can be 400 inches / minute. For 2mm thick enameled glass, the tempering temperature can be 690℃, the tempering time can be 80 seconds, and the tempering speed can be 450 inches / minute.

[0083] By optimizing the tempering parameters, the uniformity and consistency of the colored glaze glass during the tempering process can be ensured. Appropriate temperature and time can improve the tempering strength of the glass and extend its service life. Appropriate tempering speed can improve production efficiency and reduce manufacturing costs.

[0084] Exemplarily, the tempering parameters also include wind pressure in the tempering furnace, and the wind pressure corresponds to a range of 3 to 6 kPa.

[0085] Based on the above embodiment, the wind pressure parameter in the tempering furnace is further introduced. The wind pressure range is 3 to 6 kPa. By controlling the wind pressure, the cooling effect during the tempering process can be optimized to ensure that the glass surface is cooled quickly, thereby forming a uniform tempered layer.

[0086] For example, for 3mm thick colored glaze glass, the tempering temperature can be 700℃, the tempering time can be 100 seconds, the tempering speed can be 400 inches / minute, and the wind pressure in the tempering rapid cooling section can be 4.5kPa. For 2mm thick colored glaze glass, the tempering temperature can be 690℃, the tempering time can be 80 seconds, the tempering speed can be 450 inches / minute, and the wind pressure in the tempering furnace rapid cooling section can be 5.0kPa.

[0087] Controlling wind pressure can improve the uniformity of the cooling process and reduce the risk of cracking caused by uneven stress. Appropriate wind pressure can speed up the cooling process, improve the tempering effect and production efficiency. By optimizing wind pressure, the temperature gradient on the glass surface can be better controlled, reducing deformation and warping.

[0088] In some embodiments, the drilled glass has the same thickness as the frosted glass.

[0089] By selecting drilled glass of the same thickness as the enameled glass to be tempered as the adsorption material. The drilled glass of the same thickness can better simulate the thermal expansion and cooling characteristics of the enameled glass during the tempering process, thereby ensuring the stability and effectiveness of the adsorption process. If the thickness of the enameled glass to be tempered is 3mm, select drilled glass of the same thickness of 3mm. If the thickness of the enameled glass to be tempered is 2mm, select drilled glass of the same thickness of 2mm.

[0090] By making the drilled glass and the enameled glass of the same thickness, we can ensure that the heat treatment characteristics of the two are similar and the adsorption effect is more stable. The same thickness can reduce the heat treatment error caused by thickness differences and improve the accuracy and consistency of the entire tempering process. Using drilled glass of the same thickness can simplify the production process and reduce the complexity of adjusting parameters.

[0091] Exemplarily, the preset number includes a first sub-preset number and a second sub-preset number, the second sub-preset number is equal to the number of the colored glaze glasses; the drilled glass according to the preset number is tempered in the ceramic roller to absorb excess sulfur dioxide gas when the protective film is formed in the furnace body, including: using the first sub-preset number of drilled glasses to be tempered in the ceramic roller to absorb excess sulfur dioxide gas when the protective film is formed in the furnace body; completing the tempering of the colored glaze glasses according to the tempering parameters in the ceramic roller after completing the adsorption of sulfur dioxide gas, including: tempering the drilled glass of the second sub-preset number and each of the colored glaze glasses alternately in the ceramic roller to increase the distance between the multiple colored glaze glasses, balance the front and rear tempering temperatures of the colored glaze glasses, and improve the glaze maturity and glass flatness of the colored glaze glasses.

[0092] Please refer to Figure 2 ,exist Figure 2 middle, Figure 2 (a) is a schematic flow chart of the principle of the interval tempering method provided in one embodiment of the present application, Figure 2 (b) is a schematic flow chart of the principle of the pre-pulling furnace tempering method provided in an embodiment of the present application. The preset number is divided into a first sub-preset number and a second sub-preset number. The first sub-preset number is used for the number of drilled glasses that initially absorb excess sulfur dioxide gas. The second sub-preset number is equal to the number of colored glaze glasses, which are used to alternately place with the colored glaze glasses during the actual tempering process to balance the front and rear tempering temperatures of the colored glaze glasses and improve the degree of glaze burn-in and the flatness of the glass. This embodiment is Figure 2 The content corresponding to the interval tempering method in (a) Figure 2 The tempering direction is from right to left). If all the drilled glass is tempered first and then the colored glaze glass is tempered, Figure 2 (b) The first pull furnace tempering method. The interval tempering method is that the colored glaze glass and the drilled glass are tempered in the furnace alternately, and the distance between the colored glaze glasses is increased, which helps to balance the tempering temperature of the colored glaze glass before and after, and improve the glaze burning degree and the flatness of the glass. In addition, the tempered drilled glass is the back plate glass of the laminated glass, which does not affect the overall production efficiency of the glass. The first pull furnace tempering method is to use a certain amount of ordinary drilled glass to temper it first, stabilize the temperature of the tempering furnace, and then temper the colored glaze glass, which can improve the burning degree and flatness of the colored glaze glass, and at the same time, can reduce the color difference of the colored glaze glass. The corresponding tempering method can be selected according to actual needs, and the embodiments of the present application are not limited to this.

[0093] Assume that the number of colored glaze glasses to be tempered is 10. The first sub-preset number can select 5 pieces of drilled glass for initial adsorption. The second sub-preset number is the same as the number of colored glaze glasses, that is, 10 pieces of drilled glass. First, 5 pieces of drilled glass are placed in the ceramic roller for initial adsorption, and then 10 pieces of drilled glass and 10 pieces of colored glaze glasses are placed in the ceramic roller alternately for tempering.

[0094] The first preset number of drilled glasses can effectively absorb excess sulfur dioxide gas and reduce pollution to the ceramic roller and colored glaze glass. The second preset number of drilled glasses and colored glaze glass are placed alternately to balance the temperature difference between the colored glaze glasses and ensure that each piece of colored glaze glass is evenly heated during the tempering process. The alternately placed drilled glasses can reduce the thermal stress on the surface of the colored glaze glass, improve the degree of glaze burning, and ensure the uniformity and beauty of the colored glaze layer. The alternate placement of drilled glasses can reduce the mutual influence between the colored glaze glasses, improve their flatness, and reduce deformation and warping.

[0095] In some embodiments, the step of introducing sulfur dioxide gas into the ceramic roller of the tempering furnace comprises: introducing the sulfur dioxide gas into the ceramic roller according to a preset introduction time, introduction flow rate and introduction pressure; wherein the introduction time ranges from 0 to 5 minutes, and the introduction flow rate ranges from 1 to 4 cm 3 / min, and the input pressure ranges from 45 to 55 kPa to increase the traveling resistance of the colored glaze glass on the ceramic roller and improve the flatness of the colored glaze glass.

[0096] Sulfur dioxide gas is introduced into the ceramic roller of the tempering furnace to form a protective film on the surface of the ceramic roller. Sulfur dioxide gas is introduced into the ceramic roller according to the preset introduction time, introduction flow rate and introduction pressure. The introduction time ranges from 0 to 5 minutes. The introduction flow rate ranges from 1 to 4 cm³ / minute. The introduction pressure ranges from 45 to 55 kPa. By controlling these parameters, the travel resistance of the colored glaze glass on the ceramic roller is increased, thereby improving the flatness of the colored glaze glass.

[0097] By controlling the parameters of sulfur dioxide gas injection, a moderate protective film can be formed on the surface of the ceramic roller, increasing the resistance of the colored glaze glass on the roller. The increased resistance helps to ensure that the colored glaze glass is evenly stressed during the high-temperature tempering process, reducing deformation and warping caused by uneven stress. Appropriate injection time and flow rate can ensure that sulfur dioxide gas forms a uniform protective film on the surface of the ceramic roller, avoiding local excessive thickness or thinness. Controlling the injection pressure can ensure a stable supply of sulfur dioxide gas and improve the stability and reliability of the protective film. The protective film can reduce the direct friction between the colored glaze glass and the ceramic roller, thereby reducing scratches and other surface damage. The protective film helps to fix the colored glaze layer, avoid glaze peeling during high-temperature treatment, and improve the aesthetics and durability of the product.

[0098] At the same time, by finely controlling the input parameters, unnecessary process steps can be reduced and production efficiency can be improved. The optimized parameters ensure that each batch of enameled glass can achieve consistent high quality and reduce scrap and rework rates.

[0099] 0 to 5 minutes is the range of controlling the residence time of sulfur dioxide gas on the surface of the ceramic roller to ensure the formation and thickness of the protective film. If the passage time is 3 minutes, it can ensure that a moderate protective film is formed on the surface of the ceramic roller, which is neither too thick nor too thin.

[0100] The flow rate range is 1 to 4 cm³ / min. By controlling the amount of sulfur dioxide gas introduced, the thickness and uniformity of the protective film can be ensured. If the flow rate is 2 cm³ / min, it can ensure that the sulfur dioxide gas is evenly distributed on the surface of the ceramic roller to form a uniform protective film.

[0101] The supply pressure range is 45 to 55 kPa, which can control the supply pressure of sulfur dioxide gas and ensure the stable supply of gas and the formation of protective film. If the supply pressure is 50 kPa, it can ensure that sulfur dioxide gas forms a stable protective film on the surface of the ceramic roller, reducing bubbles and unevenness.

[0102] By increasing the running resistance of the colored glaze glass on the ceramic roller, the glass is evenly stressed during high temperature treatment, reducing deformation and warping. The optimized feeding parameters can form a uniform and stable protective film, reduce surface friction and glaze peeling. Reduce scratches and other surface damage, improve the aesthetics and yield of the colored glaze glass. Through parameter optimization, the production process is simplified, production efficiency is improved, and manufacturing costs are reduced.

[0103] Through this embodiment, the flatness problem that may occur in the tempering process of colored glaze glass can be effectively solved, and the overall quality and production efficiency of the product can be improved, thereby better meeting the architectural design and aesthetic requirements.

[0104] In some embodiments, obtaining the tempering parameters corresponding to the colored glaze glass according to the thickness of the colored glaze glass includes: obtaining glaze information and glass substrate information corresponding to the colored glaze glass; and generating the tempering parameters according to the thickness, glaze information and glass substrate information.

[0105] After determining the thickness of the colored glaze glass, first obtain the glaze information and glass substrate information corresponding to the colored glaze glass. According to the thickness, glaze information and glass substrate information of the colored glaze glass, generate the corresponding tempering parameters. The tempering parameters usually include tempering temperature, tempering time, tempering speed, etc., to ensure the best tempering effect.

[0106] For example, the thickness of the tempered colored glaze glass is 3mm, the glaze is a glaze of a certain color and composition, and the glass substrate is low-iron glass. The glaze of a specific color needs to be sintered within a certain temperature range to ensure the uniformity and stability of the color. Low-iron glass has high transparency and a small thermal expansion coefficient, and needs to be tempered at an appropriate temperature and cooling rate to avoid cracks and deformation.

[0107] Resulting tempering temperature: 710°C (intermediate temperature selected based on the characteristics of the glaze and glass substrate). Tempering time: 120 seconds (time determined by glass thickness and substrate characteristics). Tempering speed: 450 inches / minute (to ensure uniform cooling and production efficiency). Wind pressure: 4.5kPa.

[0108] By generating tempering parameters according to the specific thickness, glaze information and glass substrate information of the colored glaze glass, the characteristics of different materials can be better adapted to improve the tempering effect. Universal tempering parameters may not be suitable for all types of colored glaze glass. By generating personalized parameters, uneven tempering or quality problems caused by parameter mismatch can be avoided. Ensure that the glaze can be fully sintered and the color is uniform during the tempering process, which improves the aesthetics of the product. Selecting appropriate tempering parameters according to the characteristics of the glass substrate can reduce cracks and deformation and improve the strength and stability of the product. By generating the optimal tempering parameters, it can be ensured that each piece of colored glaze glass achieves the best tempering effect in the shortest time, improving the efficiency of the production line. Personalized parameters can reduce the scrap rate caused by improper tempering parameters and reduce production costs.

[0109] In summary, the tempering process of colored glaze glass can be controlled more accurately to ensure that each piece of colored glaze glass can achieve the best quality and performance, thereby better meeting market demand.

[0110] Exemplarily, before generating the tempering parameters according to the thickness, glaze information and glass substrate information, it also includes: obtaining historical colored glaze information; the historical colored glaze information includes historical glass thickness, historical tempering parameters, historical glaze information and historical substrate information; inputting the historical glass thickness, historical glaze information and historical substrate information into a pre-trained parameter generation model, and the parameter generation model outputs predicted tempering parameters; completing the training of the parameter generation model according to the predicted tempering parameters and the historical tempering parameters, so as to input the thickness, glaze information and glass substrate information into the trained parameter generation model to obtain the tempering parameters.

[0111] Before generating new tempering parameters, first obtain historical glaze information. The historical glaze information includes historical glass thickness, historical tempering parameters, historical glaze information, and historical substrate information. Input this historical information into the pre-trained parameter generation model, and the model outputs predicted tempering parameters. The parameter generation model is further trained based on the predicted tempering parameters and the actual historical tempering parameters to improve the accuracy of the model. Finally, the thickness, glaze information, and glass substrate information of the new glazed glass are input into the trained parameter generation model to obtain tempering parameters suitable for the new glazed glass.

[0112] For example, the thickness of the tempered colored glaze glass is 3mm, the glaze is a certain color glaze, and the glass substrate is low-iron glass. Historical glass thickness: 3mm, 4mm, 2mm, etc. Historical tempering parameters: Tempering temperature of 3mm glass: 710℃, tempering time: 120 seconds, tempering speed: 450 inches / minute. Tempering temperature of 4mm glass: 720℃, tempering time: 150 seconds, tempering speed: 400 inches / minute. Tempering temperature of 2mm glass: 700℃, tempering time: 100 seconds, tempering speed: 500 inches / minute. Historical glaze information: glaze information of different colors and compositions. Historical substrate information: low-iron glass, ordinary glass, etc.

[0113] The above historical information is input into the pre-trained parameter generation model, and the model outputs the predicted tempering parameters.

[0114] According to the comparison between the predicted tempering parameters and the actual historical tempering parameters, the model parameters are adjusted to improve the prediction accuracy of the model. The thickness of the new glazed glass (3mm), glaze information and glass substrate information are input into the trained parameter generation model, and the model outputs new tempering parameters. The new tempering parameters are tempering temperature 710℃, tempering time 120 seconds, and tempering speed 450 inches / minute.

[0115] Through pre-training with historical data, the model can more accurately predict the tempering parameters suitable for new colored glaze glass. Compare and train the predicted parameters with the actual historical parameters to further optimize the accuracy of the model. Generate tempering parameters using historical data to reduce the number and cost of trial and error in actual production. The model can quickly adjust parameters to cope with colored glaze glass of different thicknesses and materials, improving production flexibility. The generated tempering parameters can ensure that each batch of colored glaze glass can meet consistent high quality standards. Through precise parameter control, product quality variation caused by parameter differences can be reduced and the yield rate can be improved. The parameter generation model can realize the automatic generation of tempering parameters, reduce manual intervention, and improve production efficiency. The model can be adjusted in real time according to new data to adapt to changes and improvements in production processes.

[0116] Exemplarily, generating the tempering parameters according to the thickness, glaze information and glass substrate information includes: obtaining the ambient temperature corresponding to the tempering furnace and the basic tempering temperature, basic tempering time and basic tempering speed corresponding to the colored glaze glass; parsing the glass substrate information and glaze information to obtain the glass material and glaze type; obtaining the temperature adjustment coefficient, time adjustment coefficient and speed adjustment coefficient corresponding to the colored glaze glass according to the glass material and glaze information; calculating the tempering temperature according to the thickness, basic tempering temperature, ambient temperature, glaze type and temperature adjustment coefficient; calculating the tempering time according to the thickness, basic tempering time, ambient temperature, glass material and time adjustment coefficient; calculating the tempering speed according to the thickness, basic tempering speed, ambient temperature, glass material, tempering temperature and speed adjustment coefficient.

[0117] By considering the impact of changes in ambient temperature on the tempering process, more personalized tempering parameters can be generated. According to different glass materials and glaze types, the tempering parameters can be adjusted to ensure that each material can achieve the best tempering effect. Through the temperature adjustment coefficient, the tempering temperature is ensured to be within the appropriate range to avoid excessively high or low temperatures affecting the performance of the glaze and glass substrate. Through the time adjustment coefficient, the tempering time is ensured to be sufficient but not too long to avoid glass deformation and cracks. Through the speed adjustment coefficient, the cooling process is ensured to be uniform and the problems caused by uneven stress are reduced. By analyzing the glass substrate information and glaze information, combined with the adjustment coefficient, accurate tempering parameters can be generated to reduce the number of trial and error and cost in actual production. New tempering parameters can be quickly generated according to new material properties to improve production efficiency. Through the adjustment coefficient, it is possible to flexibly deal with colored glaze glass of different thicknesses, glazes and substrates, and improve the adaptability and flexibility of the production process. According to the changes in ambient temperature in actual production, the tempering parameters are adjusted in real time to ensure the stability and reliability of the production process.

[0118] It should be noted that, in some embodiments, the expression of the tempering temperature includes:

[0119] ;

[0120] The expression of the tempering time includes:

[0121] ;

[0122] The expression of the tempering speed includes:

[0123] ;

[0124] Among them, the is the tempering temperature, is the tempering time, The tempering speed, is the ambient temperature, , and are the basic tempering temperature, basic tempering time and basic tempering speed respectively, is the thickness, and are the standardized values ​​of the glaze type and glass material, , , They are respectively the temperature adjustment coefficient, time adjustment coefficient and speed adjustment coefficient.

[0125] Temperature control takes into account the influence of thickness, glaze type, glass material and ambient temperature, generating a more accurate tempering temperature. Time control takes into account the influence of thickness, glass material and ambient temperature, generating a more accurate tempering. Speed ​​control takes into account the influence of thickness, glass material, tempering temperature and ambient temperature, generating a more accurate tempering speed.

[0126] By introducing the ambient temperature, it is possible to adapt to the tempering requirements under different environmental conditions. By introducing standardized values ​​for glass materials and glaze types, it is possible to adapt to the tempering requirements of different materials. Using specific formulas and adjustment coefficients, tempering parameters suitable for specific colored glaze glass can be quickly generated, reducing the number of trial and error times and costs in actual production. Tempering parameters can be quickly adjusted according to real-time temperature changes in the production environment to improve production efficiency. Through precise parameter control, the uniformity and stability of colored glaze glass during the tempering process are ensured, reducing problems such as cracks and deformation. The generated tempering parameters can ensure that each batch of colored glaze glass can meet consistent high quality standards.
