METHOD FOR MAKING WASTE PLASTIC MATERIAL MIXTURE CONTAINING CHLORINE-CONTAINING RESIN HARMLESS

摘要

PPROBLEM TO BE SOLVED: To make a waste plastic material mixture containing chlorine-containing resins harmless without discharging harmful materials. PSOLUTION: This method for making the waste plastic material mixture containing the chlorine-containing resins harmless is provided by mixing a necessary amount of zinc oxide to the waste plastic material mixture containing the chlorine-containing resins, thermally decomposing at 180-300C and washing to remove chlorine components. The produced zinc chloride is reused by returning to zinc oxide. PCOPYRIGHT: (C)2006,JPO&NCIPI
