RECOVERY OF WASTE RESIN BAMPER, WOODEN SYNTHETIC POWDER COMPOSED OF RECOVERED RESIN MATERIAL RECOVERED FROM WASTE RESIN BAMPER, ITS PRODUCTION AND HOLLOW WOODEN SYNTHETIC PANEL USING WOODEN SYNTHETIC POWDER

摘要

PROBLEM TO BE SOLVED: To recover a resin material to be used as a raw material by a simple and easy means by crushing a waste resin bamper into a large number of small pieces to be treated and applying compression impact force based on micro-vibration to the small pieces and further again performing crushing to crush re-crushed pieces. SOLUTION: A waste resin bamper made of polypropylene is crushed into small pieces 12 to be treated and these small pieces 12 are crushed and stretched by a compression impact force applying apparatus 30 in a primary treatment process to be formed into a thin and flat shape. The impact force applying apparatus 30 applies impact force to these small pieces 12 to be treated continuously in a rotary direction with respect to an outside compression impact member 43 and an inside compression impact member 33 having an impact surface 33a set to an outward truncated cone shape to stretch the small pieces. In a secondary treatment process, flat small pieces obtained in the primary treatment process are re-crushed and re-stretched by a compression impact force applying apparatus to be formed into a thin and flat shape (about 66mm). A recovered resin material having this thin and flat shape is crushed by a crushing means such as a cutter mill.
