Equipment summary:
This test equipment simulates corrosion tests in artificial environments and is suitable for determining the adaptability of electrical and electronic products and their materials under chemical corrosion environmental conditions, as well as for testing the quality of metal materials with or without corrosion protection;
Suitable for rapid analysis of phenomena such as discontinuities, pores, and damage in organic and inorganic coatings in anti-corrosion tests. In addition, for quality control purposes, comparisons can be made between samples coated with the same coating;
The salt spray test is particularly suitable for detecting discontinuities such as small pores and other defects in certain metal, organic, anodized, and conversion coatings, where
1. Neutral salt spray test (NSS) is applicable to metals and their alloys, metal coatings (anode and cathode), conversion coatings, anodized coatings, and organic coatings on metal materials;
2. The acetic acid salt spray test (AASS) and the copper accelerated acetic acid salt spray test (CASS) are particularly suitable for testing decorative coatings of copper+nickel+chromium, or nickel+chromium; Also suitable for testing anodized coatings on aluminum;
3. Test method for high concentration so2 test;
