▎ 摘　　要

NOVELTY - A valve has a plastic lining containing 60-80 parts mass ultra-high-molecular-weight polyethylene resin having molecular weight of 3500000-4000000, 2-6 parts mass N,N'-ethylene bisstearamide, 2-4 parts mass molybdenum disulfide, 4-6 parts mass graphene oxide, 4-6 parts mass chopped carbon fiber, 8-10 parts mass polyethylene wax and 3-5 parts mass flake graphite. USE - Valve (claimed). ADVANTAGE - The valve has excellent corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of valve, which involves dispersing graphene oxide in water for 10 minutes, regulating pH value to 2-5, adding chopped carbon fiber, flake graphite and ultra-high-molecular weight polyethylene to obtained solution, ultrasonically processing for 15 minutes, filtering, drying, mixing obtained powder with N,N'-ethylene bisstearamide, molybdenum sulfide and polyethylene wax, stirring, extruding and granulating.
