Anti Corrosive Chemical Agent Silica Dioxide

What is anti corrosive Silica Powder?

As environmental regulations become increasingly stringent, all types of anti-rust pigments containing heavy metals, such as lead,

chromium and mercury, will be gradually phased out. In addition, zinc phosphate and its modified anti-rust pigments also face control

risks, and their anti-corrosion performance cannot meet higher performance requirements. Therefore, researchers are looking for more

environmentally friendly and better-performing anti-rust pigments.

Silica anti-rust pigments are mainly composed of silica, which is chemically inert, non-toxic and harmless, and is an ideal environmentally

friendly material. At the same time, its unique anti-corrosion mechanism gives it excellent performance. On the one hand, the silica carrier

is slightly dissolved in a corrosive environment to form an iron silicate passivation film; on the other hand, calcium ions can exchange with

corrosive ions to reduce the attack on the substrate, while producing calcium-iron silicate, further improving the protective effect.

Silica ion exchange anti-rust silica powder is a white powder, mainly composed of calcium ion exchange type amorphous products.

Ion exchange anti-rust silica powder can exchange hydrogen ions on the paint film and substrate with calcium ions, thereby neutralizing

acidic substances and maintaining a high pH value to inhibit corrosion. At the same time, it can combine with the metal oxide film to

form a protective layer to protect the steel substrate, reduce corrosion and extend service life. This product does not contain heavy

metals and is non-toxic. It is a new type of anti-rust product developed in recent years.
