In the face of different needs of different industries, rollers also need to do the corresponding coating treatment, so as to improve or compensate the relevant performance of the roller. So what are the surface coating technologies for rollers?

01 Coating treatment

The coating treatment of the drum includes zinc plating, chromium plating, nickel plating, etc. The different coating treatment can improve the hardness, corrosion resistance, oxidation resistance and wear resistance of the drum surface. It should be noted that the thickness of these coatings will also affect the performance of the roller.

02 Teflon coating

Due to the characteristics of Teflon, the roller coated with Teflon has good high temperature resistance and anti-viscosity. Such rollers are easy to clean and can be widely used in the medical food industry.

03 Spray Painting

The roller surface spray paint treatment can make the roller obtain a certain beauty. At the same time, this layer of surface coating can also play a certain role in delaying the oxidation rate of the roller surface.

04 Tungsten carbide treatment

By high temperature plasma spraying technology, the roller surface formed a hard tungsten carbide coating. This coating has excellent wear resistance, but also has good high temperature resistance, corrosion resistance, so tungsten carbide roller in all kinds of machinery manufacturing, aerospace, automotive industry and other fields are also widely used.

05 Ceramic coating

Ceramic coating has high hardness, wear resistance, chemical stability and other excellent properties, to provide an impenetrable protective layer for the drum, so that it is protected from corrosion and oxidation. Due to the high temperature resistance of the ceramic coating, the ceramic roller can be applied under high temperature conditions.

06 Hard oxidation

Hard oxide film usually acts to enhance the surface hardness, wear resistance and other properties of the drum, thereby extending the service life of the drum. At the same time, it also has the effect of changing the surface color of the drum and improving the appearance of the drum.

Therefore, the surface coating of the drum has many benefits, and their common goal is to increase the practicality of the drum, thereby improving production efficiency.
