Jinan Tianmeng Thermal Spraying Co., LTD., as a surface engineering technology provider, uses supersonic spraying (HVOF) technology to provide high-performance tungsten carbide coating services for multi-section rolls in the paper industry.
Technological advantage
1, wear resistance: tungsten carbide coating has a high hardness, second only to diamond, can effectively resist pulp fiber, chemical and mechanical wear, reduce the wear rate of multi-section roller, extend its service cycle.
2, strong bonding force: supersonic spraying technology makes tungsten carbide particles at high speed impact on the surface of the multi-section roller, forming a tight and firm bonding layer, the adhesion between the coating and the matrix is strong, not easy to peel off.
3, high corrosion resistance: tungsten carbide coating has good chemical stability, can resist the common acid and alkali medium erosion in the papermaking process, protect the multi-node roll from corrosion.
4, surface pretreatment: cleaning, grease, grinding, to ensure that the surface of the multi-section roller clean without impurities, conducive to the combination of coating.
5, supersonic spraying: select the appropriate tungsten carbide powder, adjust the spraying parameters, spraying operations.
Post-treatment inspection: After the coating is completed, the quality inspection is carried out, including the coating thickness, hardness, bond strength and other indicators to ensure that the expected effect is achieved.
