Description
Technical field
The present invention relates generally to metal conditioner field, particularly relates to a kind of environment-protecting asepsis metal conditioner.
Background technology
Metal conditioner refers to the general name of chemical agent metallic surface being carried out to various process.Metal finishing includes oil removing, rust cleaning, phosphatization, the substrate pretreatment such as antirust, for metal coating techniques, metal protection technology are prepared, the use of substrate pretreatment quality to after this coating preparation and metal has a great impact, water soluble anti-rust agent wherein then may be dissolved in water and forms the aqueous solution, and metal can prevent rust corrosion after this aqueous solution process.Their rust inhibition can be divided three classes.
1. metal and rust-preventive agent generate the insoluble and sull of densification, thus prevent the anode dissolution of metal or promote the passivation of metal, thus suppressing corrosion of metal.This kind of rust-preventive agent is also called passivator, as Sodium Nitrite, potassium bichromate etc.In use, enough consumptions should be ensured.When using quantity not sufficient, can not form complete sull, on not covered very little metallic surface, corrosion electric current density increases, and easily causes severe local corrosion.2. metal and rust-preventive agent generate the salt of indissoluble, thus metal and corrosive medium are isolated, and avoid corrosion.Such as: the phosphoric acid salt had can generate insoluble phosphoric acid molysite with iron effect; Some silicate energy and iron, aluminium effect generate insoluble silicate etc.3. metal and rust-preventive agent generate the complex compound of insoluble, cover metallic surface and protect metal to avoid corrosion.Such as: benzotriazole and copper can generate inner complex Cu (C6H4N3) 2, be both water insolublely also insoluble to oil, thus can protect the surface of copper.
Summary of the invention
