▎ 摘  要

NOVELTY - Manufacture of injection-molded product involves mixing and compounding a plastic material which is a base material for injection-molded product, and 0.01-0.5 pts. wt. graphite having a plate-like structure and molding into an injection-molded product, mixing a plastic raw material and graphite having plate-like structure, and injecting the mixed raw material into a mold. The content of a calcium carbonate is 0.5-5.0 pts. wt. based on 100 pts. wt. plastic material. USE - Manufacture of injection-molded product e.g. pipe and sewage inlet. ADVANTAGE - The method provides pipe having excellent yield, mechanical durability, weather resistance, chemical resistance and ensures long-term durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a non-metal extrudate, which comprises a graphite composite with a plate-like structure containing the graphite and calcium carbonate with a plastic material as a base.
