Preparation of Anticorrosive And Wear-resistant Coating of Teflon + Tungsten Carbide on Paper Dryer by Supersonic Spray Processing

Dryer is a key component in paper machine, and its surface condition has a direct influence on paper quality. In order to improve the durability of the dryer and reduce maintenance costs, tungsten carbide and Teflon coatings can be applied to the surface of the dryer. Tungsten carbide coating, due to its extremely high hardness and good electrical conductivity, can significantly improve the wear resistance and corrosion resistance of the dryer. The Teflon coating reduces pulp residue and improves dryer cleaning efficiency due to its excellent non-stick and high temperature resistance.

The combination of tungsten carbide and Teflon coating applied to the dryer surface brings out the best of both materials, resulting in the following benefits：

1, improve wear resistance: the high hardness of tungsten carbide can resist long-term wear and prolong the service life of the dryer.

2, enhance corrosion resistance: the chemical stability of tungsten carbide and the acid-base resistance of Teflon work together to improve the resistance of the coating to chemicals.

3, reduce maintenance costs: the coating's non-viscosity and wear resistance reduce the frequency of cleaning and maintenance, reducing the risk of production disruption.

4, improve the quality of the paper: the smooth surface of the coating helps the paper to dry evenly and improve the quality of the final product.

Application field of coating：

In addition to the paper industry, this coating technology can also be widely used in the preparation of surface anti-corrosion, wear-resistant, non-stick and other functional coatings for equipment in petroleum, machinery manufacturing and other industries
