[0028] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0029] Existing standard test methods suffer from problems such as long prediction cycles and high costs for corrosion levels.

[0030] To address the aforementioned problems, this invention provides a method for predicting atmospheric corrosion levels, such as... Figure 1 As shown, the method includes:

[0031] Step 10: Obtain the environmental parameters of the meteorological environment in which the component is located, wherein the environmental parameters include air temperature, temperature difference, humidity, precipitation, solar radiation and sulfur dioxide concentration.

[0032] The components include metal components, non-metal components, and components made of other materials. Metal components specifically include carbon steel, low alloy steel, stainless steel, etc., while non-metal components specifically include concrete, polymers, etc. Components made of other materials specifically include coating materials, welded joints, etc.

[0033] The embodiments of the present invention are mainly applicable to atmospheric corrosion level prediction scenarios, and the executing subject of the embodiments of the present invention is a device or equipment capable of predicting atmospheric corrosion levels.

[0034] In order to predict the corrosion level, it is necessary to collect environmental parameters of the atmospheric environment in which the component is located in advance. These environmental parameters specifically include: air temperature, temperature difference, humidity, precipitation, solar radiation and sulfur dioxide concentration.

[0035] For example, the obtained temperature was 27.8℃, the temperature difference was 3.5℃, the humidity was 94.3%, the precipitation was 83.0 mm / h, the solar radiation was 18774.9 W / m2, and the sulfur dioxide concentration was 0.22%.

[0036] Step 20: Calculate the amount of salt deposition in the meteorological environment based on the air temperature, the temperature difference, and the precipitation.

[0037] For this embodiment of the invention, the specific calculation process for salt deposition includes, in step 20: obtaining the volume and material density of the component, and the duration of the component in the air; calculating the latent heat of the water-bearing atmosphere based on the air temperature; calculating the water film condensation rate on the surface of the component based on the latent heat of the water-bearing atmosphere, the volume, the material density, the specific heat capacity of the water-bearing atmosphere, the temperature difference, and the duration; calculating the saturated vapor pressure using the Antoine equation based on the air temperature; and calculating the saturated vapor pressure using Dalton's law of evaporation based on the saturated vapor pressure, the density of the water-bearing atmosphere, the molecular weight of water, the gas constant, and the air temperature. The process involves calculating the rate difference between the water film condensation rate and the water film evaporation rate, and determining the thickness of the water film in different time periods based on this rate difference. Based on the thickness of the water film and the salt concentration in the air in different time periods, the amount of salt deposited in different time periods is calculated. For any given time period, if the precipitation is greater than a preset precipitation amount, the amount of salt deposited in that time period is reset to zero to obtain the actual amount of salt deposited in different time periods under the influence of precipitation. The actual amount of salt deposited in different time periods is accumulated to obtain the amount of salt deposited in the meteorological environment.

[0038] Specifically, we first consider the effect of temperature difference on water vapor in humid air, which condenses into a water film on the surface of the component. The formula for calculating the water film condensation rate is as follows.

[0039] (1)

[0040] in, Represents the rate of water film condensation; V Represents the volume of the component; ρ 1 represents the material density; C Represents the specific heat capacity of water-containing atmosphere, 1000 J / (kg·K); Represents temperature difference; H Represents the latent heat of the water-bearing atmosphere; t This represents the duration of the weather environment in which the component is located.

[0041] Furthermore, the formula for calculating the latent heat of water-bearing atmospheres is as follows:

[0042] (2)

[0043] in, T It represents temperature.

[0044] Furthermore, the water film evaporation rate can be calculated using Dalton's law of gas evaporation, with the specific formula as follows:

[0045] (3)

[0046] in, U Represents the rate of water film evaporation; ρ 2 represents the density of the water-bearing atmosphere, which is 1.205 kg / m³. 3 ; Represents saturated vapor pressure; The molecular weight of water is 18. R The gas constant is 8.314 J / mol; T Represents air temperature (°C).

[0047] Saturated vapor pressure (kPa), which can be calculated using the Antoine equation:

[0048] (4)

[0049] Furthermore, the rate difference between the water film condensation rate and the water film evaporation rate is calculated. Based on this rate difference, the thickness of the water film at different time periods can be obtained, such as the daily water film thickness, using the following specific formula.

[0050] (5)

[0051] When the saline film evaporates, salt deposits form. Based on the salt concentration in the air, the amount of salt deposited over different time periods can be calculated using the following formula.

[0052] (6)

[0053] in, Representative time period i The amount of internal salt deposition, This represents the salt concentration in the air.

[0054] When there is no rainfall, the deposited salt will accumulate daily, and the amount of salt deposited can be calculated using the following formula:

[0055] (7)

[0056] in, Salt deposition amount represents meteorological environment.

[0057] Furthermore, if a certain period of time i Excessive rainfall, such as exceeding 10 mm / h, can erode corrosion products, causing the salt deposited on the surface of objects to be washed away.

[0058] Step 30: Calculate the water vapor content per unit volume of air in the meteorological environment based on the temperature and humidity.

[0059] In this embodiment of the invention, the calculation process for the water vapor content per unit volume of air includes, in step 30: inputting the molarity definition into the gas equation of state to obtain the substituted gas equation of state; deriving the vapor pressure definition of water based on the relationship between saturated vapor pressure and temperature, and the definition of relative humidity; substituting the substituted gas equation of state into the vapor pressure definition of water to obtain the water vapor content definition; and substituting the temperature and humidity into the water vapor content definition to calculate the water vapor content per unit volume of air in the meteorological environment.

[0060] Specifically, the relationship between saturated vapor pressure and temperature is as follows:

[0061] (8)

[0062] in, Represents saturated vapor pressure. T It represents temperature.

[0063] The specific definition of relative humidity is as follows:

[0064] (9)

[0065] in, RH Represents relative humidity.p This represents the vapor pressure of water.

[0066] Based on the above formulas (8) and (9), the definition of water vapor pressure can be derived as follows:

[0067] (10)

[0068] Furthermore, the gas law is as follows:

[0069] (11)

[0070] in, Represents gas volume (m 3 ), Represents thermodynamic temperature (K). n The amount of substance (mol) representing a gas. R This represents the gas constant.

[0071] The specific formula for the amount of substance is:

[0072] (12)

[0073] in, m Represents gas mass. M Represents the molar mass of a gas.

[0074] Substituting formula (12) into formula (11), we get:

[0075] (13)

[0076] Substituting formula (13) into formula (10), we get:

[0077] (14)

[0078] in, W This represents the water vapor content per unit volume of air. Represents the molar mass of water (18 g / mol). T Represents temperature, RH Represents relative humidity (%) R The gas constant is 8.314 J / mol. Therefore, the water vapor content per unit volume of air can be calculated using the above formula.

[0079] Step 40: Calculate the radiation intensity factor of the meteorological environment based on the air temperature and the solar radiation.

[0080] In this embodiment of the invention, step 40 specifically includes the following steps in the calculation process of the radiation intensity factor: calculating the surface temperature rise of the component caused by solar radiation using the Stefan-Boltzmann law based on the solar radiation amount; calculating a first reaction rate constant using the Arrhenius formula based on the surface temperature rise of the component; calculating a second reaction rate constant using the Arrhenius formula based on the air temperature; and calculating the radiation intensity factor of the meteorological environment based on the first reaction rate constant and the second reaction rate constant.

[0081] Specifically, when sunlight shines on a component, its surface heats up due to the absorption of solar radiation. According to the Stefan-Boltzmann law, the increase in surface temperature caused by solar radiation can be determined by the following formula:

[0082] (15)

[0083] in, This represents the temperature rise of the component surface. P Represents solar radiation intensity (W / m 2 σ is the Stefan-Boltzmann constant, approximately 5.67 × 10⁻⁶. -8 W / (m 2 K 4 ).

[0084] The Arrhenius formula is as follows:

[0085] (16)

[0086] in, Representing the activation energy, the activation energies of concrete and steel are approximately 30 kJ / mol and 75 kJ / mol, respectively. From this, the radiation intensity factor γ can be defined, with the specific formula as follows:

[0087] (17)

[0088] The radiation intensity factor γ can reflect the influence of solar radiation on erosion intensity.

[0089] Step 50: Calculate the pollutant acceleration factor of the meteorological environment based on the sulfur dioxide concentration.

[0090] In this embodiment of the invention, when calculating the pollutant acceleration factor, the sulfur dioxide concentration is substituted into the natural exponential function for calculation to obtain the pollutant acceleration factor of the meteorological environment.

[0091] Specifically, the pollutant mainly refers to sulfur dioxide (SO2). SO2 is a significant accelerator of atmospheric corrosion, with a complex mechanism and significant harmful effects. The corrosion rate of carbon steel in air containing 0.1% SO2 can be up to five times that in clean air; therefore, it is necessary to define a pollutant acceleration factor. The specific formula is as follows:

[0092] (18)

[0093] in, This represents the concentration of SO2 in the atmosphere.

[0094] Step 60: Determine the corrosion intensity factor of the meteorological environment based on the salt deposition amount, the water vapor content, the radiation intensity factor, and the pollutant acceleration factor.

[0095] This invention establishes a corrosion intensity factor model from four dimensions: salt deposition amount, water vapor content, radiation intensity factor, and pollutant acceleration factor. The calculation formula for the corrosion intensity factor is as follows:

[0096] (19)

[0097] As can be seen from the above formula, the corrosion intensity factor of the meteorological environment can be obtained by multiplying the salt deposition amount, water vapor content, radiation intensity factor and pollutant acceleration factor.

[0098] Step 70: Determine the atmospheric corrosion level of the meteorological environment based on the corrosion intensity factor.

[0099] In this embodiment of the invention, after calculating the corrosion intensity factor, the corrosion rate is first determined based on the corrosion intensity factor, and then the atmospheric corrosion level of the meteorological environment is determined by querying a preset corrosion level table based on the corrosion rate.

[0100] Specifically, the correspondence between corrosion intensity factor and corrosion rate is established in advance, as shown in Table 1, and corrosion level classification is established accordingly.

[0101] Table 1. Correlation between corrosion intensity factor K and corrosion rate

[0102]

[0103] After determining the corrosion rate corresponding to the corrosion intensity factor, the atmospheric corrosion level is judged by referring to the corrosion rate-corrosion level classification table in the national standard GB / T19292.1-2018 (corresponding to the international standard ISO 9223:2012) based on the annual corrosion rate.

[0104] In some embodiments, besides using a corrosion intensity factor model to calculate the corrosion intensity factor and thus predict the corrosion rate, a neural network algorithm can also be used to predict the corrosion rate. Specifically, salt deposition, water vapor content, radiation intensity factor, and pollutant acceleration factor can be divided into multiple ranges, with different ranges corresponding to different encoding vectors. Taking salt deposition as an example, if the salt deposition falls within range A, its corresponding encoding vector is 001; if the salt deposition falls within range B, its corresponding encoding vector is 010; and if the salt deposition falls within range C, its corresponding encoding vector is 001. Thus, the encoding vectors corresponding to salt deposition, water vapor content, radiation intensity factor, and pollutant acceleration factor can be determined based on their respective ranges. Then, the encoding vectors corresponding to salt deposition, water vapor content, radiation intensity factor, and pollutant acceleration factor are horizontally concatenated to obtain a corrosion feature vector. This corrosion feature vector is then input into a preset corrosion rate prediction model for prediction to obtain the corrosion rate range. Finally, the atmospheric corrosion level is determined based on the corrosion rate range. Specifically, the preset corrosion rate prediction model can be a multilayer perceptron.

[0105] This invention provides an atmospheric corrosion level prediction method, which is essentially a mechanistic method. It does not require long-term field data or significant cost investment, and can predict corrosion levels based on environmental parameters, thus solving the problems of long prediction cycles and high costs associated with existing technologies. Simultaneously, this invention establishes a corrosion intensity factor model based on four dimensions—salt deposition, water vapor content, radiation intensity factor, and pollutant acceleration factor—and aligns it with national standards for corrosion level classification, establishing a corrosion level classification method based on environmental parameters. This enables the prediction of the corrosion level of components in the atmospheric environment.
