Dryer is an important part of a paper-making machinery and equipment, drying internal needs through 120 ℃ steam, direct contact with the outside surface corrosive medium in the pulp can lead to serious corrosion on the surface of the cylinder, and the surface of the cylinder is in contact with the scraper, prone to wear and tear problems, drying cylinder surface corrosion and wear, will directly cause quality problems such as paper, fracture, not smooth.
The metal coating is sprayed on the surface by supersonic arc spraying. The coating formed by thermal spraying has many significant advantages: the bonding strength between the coating and the substrate is relatively high; Significant corrosion wear resistance; High energy efficiency, low spraying cost; The cost of the equipment is relatively low, the use and maintenance is convenient, and the site construction is convenient.
If you want to get a better surface coating quality, you can use supersonic flame spraying tungsten carbide coating, which will last longer than arc spraying.
Because the diameter of the dryer is large and the weight is large, the maintenance and transportation of the dryer is very inconvenient. Our company not only has mature dryer spraying experience, but also can achieve in the customer use site, at home, online spraying and grinding polishing.
