Carbon Fiber Scraper Doctor Blades for Paper Machine

Carbon fiber scraper is a high-performance scraper made of carbon fiber cloth or carbon fiber cloth and other fiber cloth (such as glass fiber cloth) and silicon carbide fiber cloth or zirconium corundum fiber cloth. It is made through specific manufacturing processes, such as pre-impregnation, cutting, laying, heating and pressurizing curing. Carbon fiber scraper has good wear resistance, pressure resistance and high temperature resistance, and also has low water absorption and excellent self-lubricating properties.

Production Details

Features

Suitable for cleaning drying cylinders, calenders, center rollers, etc.
Thanks to the self-lubricating property of carbon fiber, high carbon content scraper
Better moisturizing, more wear-resistant, better able to protect the cylinder surface
