The result of the judgment after entering the salt spray corrosion test room

What kinds of methods are there for judging its quality in the walk-in salt spray corrosion test chamber? The weighing judging method is to calculate the corrosion resistance weight of the sample by weighing the weight of the sample before and after the corrosion test. For evaluation, it is especially suitable for assessing the corrosion resistance quality of a certain metal; the corrosive matter appearance judgment method is a qualitative judgment method. After the salt spray corrosion test, whether the product has a corrosion phenomenon to judge the sample, generally Most of the product standards adopt this method; the statistical analysis method of corrosion data provides a method for designing corrosion tests, analyzing corrosion data, and determining the confidence level of corrosion data. It is mainly used for analysis and statistics of corrosion, not for specific use. The quality of the product is determined.

步入式盐雾腐蚀试验室的判断标准之后的结果宣判

The basic content of the walk-in salt spray corrosion test is that a 5% aqueous solution of sodium chloride is sprayed in the test chamber at 35° C. to simulate the accelerated corrosion process of the seawater environment. The length of the resistance time determines the corrosion resistance. Good or bad. Salt spray box volume is not less than 012m3, preferably not less than 014m3, temperature inside the box is 35°C±2°C, spray pressure is 70~170kpa, salt spray collector is at least two, collection area is 80cm2, and the tested surface is in vertical direction 15 ~30 degrees allow the salt spray to settle freely on the surface to be measured, cannot be directly sprayed, the test stand is made of glass, plastics are made, the test pieces cannot contact each other, and each drips; the temperature inside the box is 35°C±2°C, and each collector collects Solution.
