What is the purpose of stainless steel surface treatment
2023-05-31
Dalian metal surface treatment mainly aims to remove oil and dirt. Its main components are sodium carbonate, sodium metasilicate, etc., and anionic surfactants or dispersants are added to make industrial cleaning agents. Machines such as ultrasonic machines are used to remove impurities. The shortcomings of this treatment agent are mainly reflected in the complex processing process, which requires heating the treatment agent and consumes a large amount of water resources; At the same time, cleaning takes a relatively long time. It mainly forms a phosphating film on the outer surface of the metal through the joint action of substances such as phosphoric acid and surfactants. It can not only achieve the purpose of oil and rust removal, but also isolate air and achieve the purpose of rust prevention.
