Rollers

Sizing rollers: In the papermaking process, the sizing rollers need to evenly coat the glue on the surface of the paper. Through thermal spraying ceramic coatings, such as alumina coatings, the hardness and smoothness of the surface of the sizing roller can be improved, so that it has good wear resistance and corrosion resistance, ensuring that the glue is evenly coated and improving the sizing quality of the paper. At the same time, the ceramic coating also prevents the chemicals in the glue from eroding the roller surface and prolongs the service life of the glue roller.

Press rollers: Press rollers are used to squeeze the paper and remove moisture from the paper. Thermal spray metal alloy coatings, such as nickel-based alloy coatings, can enhance the wear and fatigue resistance of press rolls. In the high-pressure extrusion process, the coating can effectively resist the friction between the paper and the roll surface, reduce wear, maintain the flatness and finish of the roll surface, and thus improve the pressing effect and quality of the paper. ·

Rolls: Rolls are a key component in the steel rolling process and are subjected to tremendous pressure and friction. Thermal spray tungsten carbide coating can significantly improve the hardness and wear resistance of rolls, so that they can resist high temperature, high pressure and metal-to-metal friction during the rolling process, reduce the wear and deformation of rolls, and improve rolling accuracy and product quality. In addition, for some special rolling processes, the high temperature resistance and oxidation resistance of the rolls can also be improved by thermal spraying ceramic coating.

Straightening rollers: Straightening rollers are used to straighten rolled steel. The thermal spraying alloy coating can improve the strength and toughness of the straightening roller, so that it can withstand large bending stress and impact force during the straightening process, prevent cracks and spalling on the roll surface, and ensure the straightening effect and the quality of the steel.

Rubber roller: Rubber roller plays an important role in the printing process to transfer ink and ensure printing quality. Thermal spray polyurethane coating can make the rubber roller have good elasticity, abrasion resistance and ink corrosion resistance. The coating enables precise control of the surface hardness and roughness of the rollers, ensuring uniform ink transfer and improving print clarity and color saturation. At the same time, the polyurethane coating can also effectively prevent the erosion of the ink on the rubber roller and prolong the service life of the rubber roller. ·

Imprint roller: The embossing roller is used to transfer the graphics and text on the printing plate to printing materials such as paper. The thermal spray rubber coating can give the impression roller good elasticity and pressure uniformity, so that it can be closely attached to the printing plate and printing material during the embossing process, and realize the clear transfer of graphics and text. The rubber coating also cushions the impact force during the embossing process, protects the plate and printing material, and improves the print quality and the stability of the device. ·

Cloth guide roller in the printing and dyeing industry: The cloth guide roller needs to guide the fabric through the various processes smoothly during the printing and dyeing process. Thermal spraying PTFE coating can make the surface of the cloth guide roller have a very low coefficient of friction, reduce the friction between the fabric and the roller surface, prevent the fabric from abrasion and wrinkles during the transmission process, and ensure the quality of printing and dyeing. At the same time, PTFE coating also has good chemical resistance, which can resist the erosion of the roller surface by chemicals in the printing and dyeing solution.

Conveyor rollers for the glass industry: In the process of glass production and processing, conveyor rollers are used to convey high-temperature glass products. Thermal spraying ceramic coating can improve the high temperature resistance and thermal stability of the conveying roller, so that it can maintain good mechanical properties and dimensional stability in the high-temperature environment, prevent the roller surface from deforming or oxidizing due to high temperature, and ensure the conveying quality and production efficiency of glass products.
