Description

Technical Field

[0001] This invention relates to the field of plastic testing, specifically to a method for testing and analyzing the corrosion resistance of plastic packaging pallets. Background Technology

[0002] Plastic pallets are widely used load-bearing units in modern logistics and warehousing, and their corrosion resistance directly affects their service life, load-bearing safety, and cargo integrity. In applications such as chemical, pharmaceutical, food, and cross-border shipping, plastic pallets are exposed to acidic and alkaline chemicals, salt spray, organic solvent vapors, and high-humidity alternating weather conditions for extended periods. This exposure can lead to corrosion and deterioration of the material's surface and internal structure, including molecular chain breakage, plasticizer precipitation, oxidative degradation, or stress cracking. These corrosions can cause a decline in the pallet's mechanical properties and even sudden structural failure, potentially resulting in cargo tipping, contamination, or personnel accidents.

[0003] Currently, the industry generally follows existing plastic corrosion resistance testing standards for testing the corrosion resistance of plastic packaging pallets. This primarily involves immersing samples in specific chemical reagents and assessing their corrosion resistance by measuring single indicators such as changes in mass, discoloration level, dimensional fluctuations, or retention of mechanical strength before and after immersion. Simultaneously, some testing methods supplement this with observation of the damaged state, that is, qualitatively describing the degree of surface cracking, blistering, or powdering of the corroded sample through visual inspection or low-magnification magnification, thereby determining whether the material meets the usage requirements.

[0004] However, the aforementioned existing technical solutions have revealed significant limitations in practical applications. Firstly, conventional testing typically focuses only on the material's bulk response to simple chemical reagent erosion, assuming the corrosion process occurs under static, clean, and constant experimental conditions with uniform chemical action. However, in real warehousing and logistics service environments, the corrosion experienced by plastic packaging pallets is far more complex than can be summarized by a single chemical factor. During long-term cyclic use, pallets are not only subjected to chemical attacks from acids, alkalis, or organic solvents, but also simultaneously endure continuous static stress from stacked goods, periodic dynamic impacts from forklift operations, thermal expansion and contraction due to drastic temperature changes, and the synergistic effect of photo-oxidation induced by ultraviolet radiation. The coupled effect of these multiple factors expands the corrosion behavior of pallet materials from a simple molecular chain chemical degradation to a complex damage evolution process involving physical, chemical, and mechanical processes. Existing static immersion testing, which only targets the chemical level, cannot reflect the accelerated corrosion rate and failure mode transitions under these combined stress conditions, leading to a significant deviation between test results and actual service performance.

[0017] Figure 1 This is a schematic diagram of the method flow of the present invention.

[0018] Figure 2 This is a comparative example of the polarization curves of the test tray involved in the embodiments of the present invention. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0021] Please see Figure 1 As shown, this embodiment of the invention provides a method for testing and analyzing the corrosion resistance of plastic packaging pallets, including: S1. Mark the plastic packaging pallets to be tested as the test pallets and extract the production data of the test pallets from the database. Obtain the model number of the pallet to be tested, perform a query operation in the database, and the query result is the historical production data of all finished pallets of the same model as the pallet to be tested, which is recorded as the same production data of the pallet to be tested. The same production data includes the historical production defect rate, the historical production average dimensional deviation, and the historical production average weight deviation.

[0022] S2. Preprocess the production data of the pallet under test to obtain the initial performance evaluation threshold and corrosion resistance test evaluation threshold of the pallet under test, and transmit them to the data processor. Based on the production data of the pallet under test, and extracting production verification data from the database, the production verification data includes verification production defect rate, verification production average size deviation, and verification production average weight deviation. The production verification value of the pallet under test is obtained by processing the data. The production verification value is used to characterize the historical production performance of finished pallets of the same model as the pallet under test. The specific processing conditions for the production verification values ​​of the pallet under test are as follows: ; in, This is the production verification value of the pallet under test. Historical production defect rate This represents the historical average dimensional deviation. This represents the historical average weight deviation. To verify the production defect rate, To verify the average dimensional deviation in production, To verify the average weight deviation in production, Weighting factors for production defect rate Weighting factor for average size deviation The weighting factor for the average weight deviation in production is given by e, which is a natural constant.

[0023] It should be noted that the weighting factors for production defect rate, production average dimensional deviation, and production average weight deviation all range from 0 to 1, and satisfy the following conditions: In this embodiment, preset values ​​can be directly extracted from the database. In the application, by establishing the relationship between the production verification values ​​of the pallet under test and the verification production defect rate, verification production average size deviation, and verification production average weight deviation of the pallet under test in historical data, a mapping set is established between the production verification values ​​of the pallet under test and the verification production defect rate, verification production average size deviation, and verification production average weight deviation of the pallet under test, as well as the corresponding weight factors of the production defect rate, production average size deviation, and production average weight deviation of the pallet under test. The real-time verification production defect rate, verification production average size deviation, and verification production average weight deviation of the pallet under test are input to obtain the corresponding weight factors of the production defect rate, production average size deviation, and production average weight deviation from the mapping set.

[0024] The table below provides five examples of production verification values ​​for the pallets under test. In this example, the weighting factors for the production defect rate, average production dimensional deviation, and average production weight deviation of the pallets under test are set to 0.4, 0.2, and 0.4, respectively. The specific output production verification values ​​are shown in the table below: Table 1 Examples of Production Verification Values

[0025] As shown in the table above, This is the production verification value of the pallet under test. Historical production defect rate This represents the historical average dimensional deviation. This represents the historical average weight deviation. To verify the production defect rate, To verify the average dimensional deviation in production, To verify the average weight deviation in production.

[0026] Table 1 shows that the peer production verification values ​​of the tested pallet reflect the defect rate, average dimensional deviation, and average weight deviation of the production materials. A higher peer production verification value indicates a higher level of specific values ​​in the peer production data compared to the production verification data. This implies that the production quality of historical finished pallets of the same model as the tested pallet was relatively low, thus requiring stricter control during the performance testing of this pallet. As shown in the table, pallet number 4 has the highest peer production verification value, indicating that its peer production data is at a high level. In actual testing, the initial performance evaluation threshold and corrosion resistance testing threshold for pallet number 4 require the greatest adjustment, necessitating stricter control during its performance testing.

[0027] Based on the production verification value of the pallet under test, the initial performance evaluation threshold and corrosion resistance test evaluation threshold corresponding to each production verification value interval in the database are matched to obtain the initial performance evaluation threshold and corrosion resistance test evaluation threshold of the pallet under test.

[0028] Based on the production verification values ​​of the pallet under test, each value is mapped and matched with the production verification value ranges in the database. If the production verification value of the pallet under test is within the production verification value range in the database, then the initial performance evaluation threshold and corrosion resistance test evaluation threshold of that range are used as the initial performance evaluation threshold and corrosion resistance test evaluation threshold of the pallet under test.

[0029] S3. Perform initial performance testing on the tray under test, process it to obtain the initial performance evaluation value of the tray under test, and transmit it to the data processor. The data processor receives the initial performance evaluation value of the tray under test and the initial performance evaluation threshold, performs comprehensive processing, obtains the initial test result of the tray under test, and provides feedback. Initial performance testing is performed on the test tray to obtain a 3D scan image of the test tray, and feature data of the test tray is extracted from the 3D scan image. The feature data specifically includes surface roughness and the length of the outer edge contour line. At the same time, the material data of the test tray is obtained by resonance method and hardness tester, and the material data specifically includes material strength and material hardness.

[0030] The resonance method uses an external source to excite the test tray to generate longitudinal and transverse resonances, and measures the material's natural frequency or amplitude characteristics to evaluate the material's performance.

[0031] It should be noted that the surface roughness of the pallet refers to the degree of microscopic unevenness of the pallet surface. Roughness affects the pallet's coefficient of friction, coating adhesion, and corrosion resistance. The outer edge contour line length refers to the overall line length of the pallet's outer edge contour. Material strength refers to the strength of the pallet material itself, including tensile strength, compressive strength, or shear strength. Material strength affects the pallet's maximum load-bearing capacity and durability. Material hardness refers to the pallet material's ability to resist local plastic deformation.

[0032] It is worth noting that there is a certain correlation between material strength and corrosion resistance. The microstructure of a material, such as grain size, phase transformation, and defects, affects its strength and corrosion resistance. For example, fine-grained materials generally have higher strength and may also have improved corrosion resistance due to the increased number of grain boundaries. Conversely, the corrosion process can affect the mechanical properties of a material, including its strength. For instance, corrosion can weaken grain boundaries, thereby reducing the material's strength.

[0033] Based on the feature data and structural inspection data of the test tray, an initial performance evaluation value for the test tray is obtained through comprehensive processing. This initial performance evaluation value is used to quantitatively characterize the material physical properties of the test tray. Specific processing conditions are as follows: ; Where G is the initial performance evaluation value of the tray under test. The surface roughness of the tray to be tested. The length of the outer edge contour line of the tray to be measured. The material strength of the tray to be tested, The material hardness of the tray to be tested. The ideal surface roughness in the database, The ideal edge contour line length in the database. For the ideal material strength in the database, The ideal material hardness in the database, This represents the maximum permissible surface roughness error value in the database. This represents the maximum permissible error value for the outer edge contour line length in the database. This represents the maximum permissible material strength error value in the database. This represents the maximum permissible material hardness error value in the database.

[0034] It should be noted that surface roughness can indirectly affect the strength and hardness of a material. For example, materials with rough surfaces, due to the presence of more microscopic defects and unevenness, may be more prone to localized stress concentration and failure under stress, thus reducing the material's strength and hardness. Conversely, materials with smooth surfaces have better mechanical properties and durability. Surface roughness and the length of the outer edge contour lines, as characteristic data, reflect the manufacturing quality and appearance of the pallet; while material strength and hardness, as material data, determine the pallet's mechanical properties and durability.

[0035] The initial performance evaluation value of the pallet to be tested is compared with the initial performance evaluation threshold. If the initial performance evaluation value of the pallet to be tested is greater than or equal to the initial performance evaluation threshold, the initial test result of the pallet to be tested is defined as a qualified pallet, and it is put into the corrosion resistance test environment for corrosion resistance test. If the initial performance evaluation value is less than the initial performance evaluation threshold, the initial test result of the pallet to be tested is defined as a non-qualified product.

[0036] S4. Perform corrosion resistance testing on the test tray, obtain the corrosion resistance test data of the test tray, and transmit it to the data processor. The data processor receives the corrosion resistance test data, performs comprehensive processing, and analyzes it in conjunction with the corrosion resistance test evaluation threshold of the test tray to obtain the corrosion resistance test evaluation result of the test tray, and then provides feedback.

[0037] The corrosion resistance of the test tray is tested to obtain the corrosion resistance test data of the test tray, which includes the polarization curve of the test tray. Based on the production data of the same type of tray under test, a corrosion resistance testing environment was constructed, and the corrosion resistance of the tray under test was tested. Based on the production data of the same type of tray under test, the corresponding solution was selected as the electrolyte. The tray under test was connected to the electrochemical workstation as the working electrode. At the same time, the saturated calomel electrode and the auxiliary electrode were connected to the electrochemical workstation to ensure that the electrodes were completely immersed in the electrolyte. Based on the production data of the test tray, the electrochemical workstation was started after setting the scanning potential range and scanning frequency. By changing the potential and measuring the corresponding current response, the polarization curve between the current density and potential of the test tray was obtained. The polarization curve of the test tray is compared with the polarization curve of an ideal corrosion-resistant standard material to obtain the comparison results and thus the corrosion resistance performance evaluation value of the test tray. The specific processing conditions are as follows: ; in, This is the evaluation value for the corrosion resistance of the tray under test. It is the corrosion potential in the polarization curve of the test tray. , It is the intersection of the corrosion potential in the polarization curve of the test tray and the corrosion potential in the ideal polarization curve. The value represents the current density in the polarization curve of the test tray. Let be the current density in the ideal polarization curve, and e be the natural constant.

[0038] The corrosion resistance test evaluation value of the pallet to be tested is compared with the corrosion resistance test evaluation threshold. If the corrosion resistance test evaluation value of the pallet to be tested is greater than or equal to the corrosion resistance test evaluation threshold, the corrosion resistance test result of the pallet to be tested is defined as a qualified pallet. If the corrosion resistance test evaluation value of the pallet to be tested is less than the corrosion resistance test evaluation threshold, the corrosion resistance test result of the pallet to be tested is defined as a non-qualified product.

[0039] like Figure 2 As shown, this is an example diagram comparing the polarization curves of the test tray involved in this embodiment. In the example diagram, the corrosion potential starts from 0, with the corrosion potential as the horizontal axis and the corrosion current density as the vertical axis. In the example diagram comparing the polarization curves of the test tray, the polarization curve of the test tray is compared with the ideal polarization curve. A baseline is constructed using the ideal corrosion current density, as shown by the horizontal dashed line in the figure, which is the ideal polarization curve involved in this embodiment. The solid line in the figure is the polarization curve of the test tray. The size of the light-colored area in the figure reflects the magnitude of the corrosion resistance performance evaluation value of the test tray to a certain extent. That is, the larger the area of ​​the light-colored area, the higher the corrosion resistance performance of the tray.

[0040] The polarization curve of the test tray is a graph depicting the relationship between the current density and potential of the material under test at a specific potential. The polarization curve provides information about the corrosion current density and corrosion potential of the material in a specific environment. By comparing the polarization curves of different materials, their corrosion resistance can be visually evaluated. For example, materials with high self-corrosion potential and low corrosion current density generally have better corrosion resistance. Based on the analysis results of the polarization curves, targeted optimization of anti-corrosion measures can be achieved.

[0041] The ideal polarization curve is generated based on the historical production data of the test tray extracted from the database. Its current density is set to a constant value and does not change with the increase of corrosion potential. In this invention, it is used to construct a baseline. When the current density of the polarization curve of the test tray does not exceed the baseline, the test tray is determined to be in the corrosion-resistant stage. When the current density of the polarization curve of the test tray exceeds the baseline, the test tray is determined to have entered the corrosion stage.

[0042] The database is used to store various historical production data and production verification data. The various production verification data include the verification production defect rate, verification production average size deviation, and verification production average weight deviation of each pallet model involved in this embodiment.

[0043] In this embodiment, the present invention provides a method for testing and analyzing the corrosion resistance performance of plastic packaging pallets. By testing the physical and chemical properties of the material of the pallet to be tested, the method solves the problem of missing physical property testing in the current corrosion resistance testing of plastic materials, prevents the pallet to be tested from having performance problems under physical collision or compression, saves testing resources, and improves the efficiency of performance testing.

[0044] This invention obtains production material data by processing and analyzing the production data of the pallet under test, and then obtains the initial performance evaluation threshold and corrosion resistance testing evaluation threshold of the pallet under test. This leads to the construction of a more accurate corrosion resistance evaluation system and improves the performance testing efficiency of the pallet under test.
