The uses of benzotriazole in the metal field are extensive, mainly reflected in corrosion inhibition, rust prevention,plating, and mechanical processing, etc., and the specific introduction is as follows:
Corrosion inhibition
Forming protective film: Benzotriazole can form complexes with metal ions (such as copper ions), and can also form covalent bonds and coordinate bonds with the metal surface. Generating linear polymers, thus forming or more layers of protective film on the metal surface. This protective film can effectively prevent the occurrence of redox reactions, prevent the production of hydrogen. And thus prevent oxidation and corrosion of metal in humid and corrosive environments. Especially for copper and its alloys, the corrosion inhibition effect is excellent.
Application in circulating water system: In circulating cooling water system, benzotriazole can use with a variety of scale inhibitors and biocides. And has a good corrosion inhibition effect on the metal in the system. Adding benzotriazole to car antifreeze can also improve the corrosion resistance of the antifreeze to metal parts.
Rust prevention
ust prevention oil and grease products: Benzotriazole is widely used in rust prevention oil, grease products. And can prevent the surface discoloration and deterioration of products. It is often use in extreme pressure industrial gear oil, hypoid gear oil, anti-wear hydraulic oil, oil film bearing oil, grease and other lubric greases. As a rust inhibitor, to extend the service life of metal.
Vapor phase corrosion inhibition: Benzotriazole can be used as a vapor phase corrosion inhibitor for and copper alloys. And inhibit the rusting of metal in a certain space.
Application in electroplating industry
Improve the quality of the plating: Addingotriazole to the electroplating solution can improve the adhesion and corrosion resistance of the plating. During the electroplating process. It can also be for surface purification of silver, copper, zinc and other metals to prevent their discoloration. In addition, in the chrome plating industry, benzotriazole can use for a chrome mist suppressant to prevent the production. And hazards of chrome mist. And increase the brightness of the plated parts.
Application in mechanical processing
In process of mechanical processing. Adding benzotriazole to grinding oil and cutting oil can prevent the copper parts from discoloring during processing. And protect the metal from during processing.
