Squeegee wrinkling is an important way to produce high-quality household paper. The wrinkling blade is a key component in the production of household paper. The quality of the scraper directly affects the quality of the product. In recent years, Tianmeng Company has cooperated with universities and colleges to conduct in-depth research on scraper blades for medium and high-speed paper machines. The wrinkle blade developed by Tianmeng Company mainly uses thermal spraying technology on the cutting edge of pre-treated steel scrapers. The tungsten carbide ceramic coating is sprayed on the cutting edge, so the ceramic part is only found on the cutting edge, and then it is prepared by grinding.
The hardness of tungsten carbide is similar to that of diamond. It is an effective protective coating that reduces workpiece wear. It is mainly used as a superhard material and wear-resistant material. It is also a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and has good corrosion resistance. Thermal spraying technology is used to spray tungsten carbide on the blade edge. The resulting coating has good wear resistance, corrosion resistance, and cavitation resistance, which greatly enhances the service life of the wrinkled scraper blade. Its main advantages are as follows:
1. It has strong corrosion resistance and edge wear resistance.
2. High manufacturing precision and good surface smoothness, which can effectively reduce the roughness of the paper surface.
3. Good performance allows the scraper to run continuously, effectively improving and stabilizing the quality of wrinkled paper.
4. There is almost no running-in time, which improves production efficiency and reduces labor intensity.
Tianmeng Company's tungsten carbide ceramic wrinkle doctor blades have been successfully developed and put into production. Customers are welcome to come for consultation and trial use.
