First, the salt spray test is a major advantage of the artificial salt spray environmental conditions created by the salt spray test equipment to assess the environmental testing of products or metal corrosion resistance. In the daily work, the need for the products of the salt spray test a number of metal products, through tests to examine the corrosion resistance of the product. For example: wire rope, high zinc wire, steel, water conservancy and commonly used in wire cages, stone cage net, Gore where the steel wire, galvanized cover plastic mesh lead, zinc and aluminum alloy gabion net flood control and flood prevention materials.
Second, do the salt spray test test purpose is to salt spray corrosion resistance of the quality evaluation of products or metal materials, salt spray test results to determine precisely the final judgment of the quality of the product, its verdict can achieve a correct and reasonable, is correctly measure the key products or metal salt spray corrosion resistance quality.
Experiment is completed, then work to the results to make comprehensive and accurate analysis and judgment, we provide you for your reference to judge according to the following four methods:
1): rating to determine
Corrosion area to total area ratio of the percentage of a certain method is divided into several levels, determined based on a certain level as a qualified, it is suitable for flat-panel samples were evaluated.
2): weighing to determine law
Is applied by the corrosion test samples before and after weight weighing measurement method to calculate the corrosion loss of weight and so corrosion of the samples to judge the quality, but this method is most suitable for quality assessment of a metal corrosion.
3): corrosion test approach
Is a qualitative judgment, salt spray corrosion test, the product is corrosive phenomenon of samples to determine, using this method, most of the general product standards.
4): corrosion data statistical analysis
Corrosion test design and analysis of corrosion data, to determine the confidence of the corrosion data, it is mainly used for analysis, statistical corrosion, rather than specific for a particular product quality judgment.
