摘要
随着煤矿开采业的发展和进步,对煤矿井下用管提出了包括保温、安全、冲击、阻燃和抗静电等新的要求。目前,国内尚无符合此类特殊要求的产品。根据煤矿井下环境要求,研制开发出聚乙烯外护套聚氨酯泡沫塑料预制保温管。
Along with the development and progress of coal mine exploration industry,new demands including heating,safety,shock resistant,flame retardant,and antistatic have arisen on the coal mine underground pipes.At present,there＇re no products reaching such special demands in China.According to underground environmental demands of the coal mine,have developed polyurethane foam plastics prefabrication insulating pipe with polyethylene outer sheath.
