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

technical field [0001] The invention belongs to the field of material engineering and its application, and relates to a polyphenylene sulfide grinding disc for papermaking and beating. Background technique [0002] Polyphenylene sulfide (PPS for short), polyphenylene sulfide is a special engineering plastic with excellent comprehensive properties. It has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardant, balanced physical and mechanical properties and excellent It has the characteristics of dimensional stability and excellent electrical insulation performance. At the same time, it has excellent heat resistance with a thermal deformation temperature greater than 260 °C after modification, and the long-term use temperature can reach 220 °C; chemical corrosion resistance is second only to polytetrafluoroethylene. vinyl fluoride. Polyphenylene sulfide has excellent molding processability and good fluidity, and can be used for thi...
