High Wear Resistance Ceramic Alloy Doctor Blade For Paper Coating Machine

The scraper is a key part of the coated paper machine. The quality of the scraper directly affects the quality of the coated paper and the production efficiency. The traditional coating scraper is a spring steel blade that has been oxidized and blued, which wears quickly and has a short life. Cloth scraper refers to the scraper after metal oxide thermal spraying and precision grinding on the surface of the pretreated steel scraper. It has many advantages such as wear resistance, long service life, and stable paper quality.
