AI Technical Summary

Technical Problem

Existing acid-proof and wear-resistant coatings are expensive, not resistant to high temperatures, flammable, and produce harmful gases when burned. They are difficult to meet the long-term protection needs under high temperature, strong corrosion, and high wear conditions in metallurgy, chemical industry and other fields.

Method used

Inorganic binders such as solid or liquid water glass are used in combination with raw materials such as silicon carbide, corundum powder, and nano-silica. The wear resistance and density of the coating are improved through surface modification. Alumina micropowder and Guangxi soil thickeners are added, and sodium fluorosilicate is used to promote coating curing.

Benefits of technology

The prepared inorganic acid-proof and wear-resistant coating has good adhesion, corrosion resistance, hardness, wear resistance, impact resistance and high temperature resistance, which improves the service life and operation stability of the equipment and reduces maintenance costs.
