anticorrosive paint
close The antirust paint used is mainly oily and water-based. Oily antirust paint makes it difficult to remove the grease on the surface of materials, and is rarely used. Oily antirust paint is easy to use and cheap, but it contains nitrite, chromate and other toxic substances, which are harmful to operators. The use of this kind of paint has been restricted by the state, and its performance is single, so it cannot meet the antirust requirements of magnetic alloy materials. The water-based metal antirust paint is mainly composed of inositol hexaphosphate, a powerful metal chelating agent, and is compounded with several other water-based additives. Inositol hexaphosphate is a natural non-toxic organic chemical product extracted from food crops. When it is used as a rust inhibitor for magnetic materials, it can quickly chelate with metal on the surface to form a dense single molecule complex protective film, which can effectively inhibit metal corrosion. The surface of the material treated by the product remains the original color, and the next process such as painting can be started without water washing. Anti rust pigment is an important part of anti rust paint. Physical anti rust pigment is a kind of pigment with relatively stable chemical properties. They rely on their physical properties, stable chemical properties, hard texture, fine particles, and excellent filling ability to improve the density of paint film, It can reduce the permeability of the paint film and thus play a role in rust prevention. Iron oxide red belongs to this kind of material. The rust prevention of metal aluminum powder is due to the scale structure of aluminum powder, which forms a compact paint film, and has a strong ability to reflect ultraviolet light, which can improve the anti-aging ability of the paint film
