Originally ultrasonic cleaning machine is used to remove dirt and rust, so why the ultrasonic cleaning machine itself will rust?
Ultrasonic cleaning machine rust causes.
1, stainless steel is divided into many types such as: 304, 316, etc., and certain materials of stainless steel will also rust, just easy to remove.
2, the surface of stainless steel stored with other metal elements containing dust or foreign metal particles of adhesion, in the humid air, adhesion and stainless steel between the condensate, the two will be connected into a microcell, triggering an electrochemical reaction, the protective film is damaged, called electrochemical corrosion.
3, stainless steel welding caused by the stainless steel weld material changes.
4, in polluted air (such as the atmosphere containing a large number of sulfides, carbon dioxide, nitrogen oxide), encounter condensate, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.
5, some components inside the ultrasonic cleaning fluid corrosion of stainless steel.
6, stainless steel surface adhesion of organic juices (such as squash, noodle soup, spit, etc.), in the presence of water and oxygen, constituting organic acids, a long time then the organic acid corrosion of the metal surface.
7, stainless steel surface adhesion containing acid, alkali, salt substances (such as decorative walls of alkaline water, lime water spray), causing local corrosion.
Ultrasonic cleaning machine cleaning tank rust solutions.
1, the decorative stainless steel surface must be cleaned and scrubbed frequently to remove adhesions and eliminate external factors that trigger rusting.
2, the use of strong acid and alkali cleaning liquid to use 316 stainless steel, 316 material can resist seawater corrosion.
3, some ultrasonic cleaning machine on the market using the chemical composition of stainless steel can not meet the corresponding national standards, not up to 304 material requirements, will also cause rust.
