摘要
研究了废导爆管经粉碎、蒸煮、漂洗、烘干生产电雷管绝缘塑头的方法。采用在废高压聚乙烯中加入液体添加剂X、更换注塑机狭小的下料管、在注塑机上安装微型搅拌机等方法,使废塑料的熔点指数达到1.85 g/10 min,拉伸强度12 MPa,熔化温度110℃,注塑温度188℃,使废塑料安全、可靠的生产电管雷绝缘塑头。
The production method of electric detonator insulation plastic head by reusing of detonating tube via crushing, digestion, rinse and drying was studied. Through adding liquid additive X in waste high-pressure polyethylene, replacing small discharge duct of injection molding machine, installing micro mixer in the injection molding machine, melting point index of treated plastic reached to 1.85 g / 10 min, tensile strength wasl2 MPa, melting temperature was 110 ℃, injection temperature was 188 ℃.So the treated plastic can be used to produce safe and reliable electric detonator insulation plastic head.
