Abstract
The invention discloses a polyphenylene sulfide millstone for papermaking pulping. The polyphenylene sulfide millstone is used for a papermaking pulping process and is made of a polyphenylene sulfide composite material. Preferably, the polyphenylene sulfide composite material comprises 30-70 weight percent of polyphenylene sulfide, 5-10 weight percent of toughening component, 20-50 weight percent of reinforced fiber and 0-20 weight percent of wear-resistant component. The polyphenylene sulfide millstone for papermaking pulping is high in thermal stability, preferably, the polyphenylene sulfide composite material with the toughening component and the reinforced fiber is adopted, the elasticity modulus is 10-30 GPa and is close to the plant fiber elasticity modulus, the millstone made of the polyphenylene sulfide composite material has a small fiber cutting effect, and the physical performance of the pulp can be effectively improved.
Description
