CASTING METHOD FOR THERMOPLASTIC COPOLYMER

摘要

PURPOSE:To provide the method of casting a thermoplastic copolymer sheet of good quality at high speed. CONSTITUTION:Liquid is applied to form its liquid film of 0.5-3mum by a reverse type coater 6 in the method of cooling and solidifying a thermoplastic copolymer extruded out of a die 1 while the static charge is applied on a casting drum 3 with its surface coated with said liquid.
