This equipment is used to test the protective layers of electrical and electronic products, electroplating products and various metal products. It is used to assess the ability of materials and their protective layers to resist corrosive gases and to compare the process quality of similar protective layers. It is an artificial simulation. The gas corrosion test uses sulfur dioxide gas to conduct accelerated corrosion tests on materials or products under a certain temperature and relative humidity environment, and compares the degree of damage suffered by the product's protective layer within a certain time range. It can also be used to evaluate the ability of certain products to resist corrosion by corrosive gases. The test results show that a lot of human, financial and material resources have been saved. Our country has adopted the sulfur dioxide gas corrosion test as a national standard and has made detailed regulations.
Reference standards
This test equipment is strictly in accordance with the national standard B/-"Sulfur dioxide corrosion test of metals and other non-organic coatings under normal condensation" promulgated by our country, and the German standard &; "Sulfur dioxide under saturated environment" Corrosion Test" and the production of international standards; as well as other standards currently in use internationally regarding sulfur dioxide and hydrogen sulfide gas corrosion.
