Papermaking fiberglass scraper is a tool specially used in papermaking machinery. Its main function is to clean the guide roller and remove dust, paper scraps and other debris on the roller to ensure the quality and production efficiency of paper. Scrapers are usually made of high-quality materials such as glass fiber, polymer polyethylene, etc., which have good durability and wear resistance.
The materials used to make glass fiber scrapers mainly include glass fiber cloth and adhesive. By pre-impregnating carbon fiber cloth and glass fiber cloth, cutting, laying, heating and pressurizing to solidify them into plates, and then slitting, grinding and sharpening them, scrapers with specific specifications and performance can be made.
