矿用软电缆的外护套层一般系采用氯丁橡胶、氯磺化聚乙烯、丁腈/聚氯乙烯、氯化聚乙烯等弹性材料制成。矿用软电缆,尤其是移动电缆和采煤机电缆,在井下因剐、冲击、挤压、炮崩,及经常不断的往复弯曲,电缆的外护套层很易受到损坏。当前常用的修补方法系硫化热补。矿用软电缆的硫化热补需要升井作业。一根中大型电缆的拆卸和更换需用大量工时,影响工作面停产时间较长;修补用的生胶带的有效贮存期又比较短,因此亟需发展电缆井下冷补的新工艺。
Outer sheath of mine soft cable is generally made of neoprene, chlorosulfonated polyethylene, nitrile / polyvinyl chloride, chlorinated polyethylene and other elastic materials. Mine cables, especially mobile cables and shearer cables, are vulnerable to damage due to buckets, impacts, crushing, gun collapse, and often repeated reciprocating bending downhole. The current commonly used method of repair is curing heat. Mining soft cable vulcanization heat needs to be well operations. Large and medium-sized cable demolition and replacement require a lot of working hours, affecting the working face longer production downtime; repair with the effective storage life of the tape is relatively short, so the urgent need to develop new technology downhole cable cold.
