▎ 摘 要
NOVELTY - A black odorous water body treatment film three-screw preparation method comprises mixing microcrystalline graphene and glass-ceramic or russellite modified components, mixing to obtain microcrystalline graphene hybrid microcrystalline glass micropowder or microcrystalline graphene hybrid russellite modified component, adding into polyethylene-polypropylene resin, blending via three-screw method, extruding, and blowing into film. USE - Black odorous water body treatment film three-screw preparation method. ADVANTAGE - The product is energy efficient, environment-friendly, multipurpose, has simple preparation and does not need aeration oxygenation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of black odorous water body treatment film comprising placing film into river or water-inverted slope area shallow water area, rectifying black and odorous water body, and using as warning line for water depth safety warning and column protection.
