As a new type of primer with water as a dispersion medium, water-based anti-rust paint is becoming more and more widely used. As we all know, a waterborne anticorrosive paint is one of the biggest advantage of the antirust function, and then guangzhou zhe Ming ink paint co., LTD. Small make up just to discuss with everybody waterborne antirust antirust way classification.
1. Physical antirust
First of all, we need to understand is that waterborne anticorrosive paint and coating metal surface basically do not produce chemical or electrochemical reaction, the commonly used does not dissolve in water, not easily destroyed by corrosion medium decomposition of chemical stability of inert pigment and filler, the coating itself is stable, and some paint filler in use at the time, can reduce water, oxygen and ion through the speed of paint film.
2. Chemical anti-rust
The method generally USES a variety of chemical reactive pigments to change the properties of surface and the properties of reaction products to prevent rust.
Electrochemical anti-rust
According to the electrochemical corrosion theory, the anode which is corroded in the corroded battery is the negative electrode. If a coating coated with metal has a lower electrode potential than metal, the coating is an anode when conditions of chemical corrosion are present.
There is a classification of anti-rust methods of water-based anti-rust paint, which is mainly introduced here. I hope you can have a new understanding and understanding of it after you have seen it. Nowadays many people need to use water-based anti-rust paint in some construction process, so it is necessary to know some relevant information. In addition, if you are looking for a professional company to buy related products, I believe that guangzhou zhe Ming ink coatings co., LTD will be a good choice.
