煤矿井下使用的橡套电缆,由于砸崩、片帮、车挤、改棚修护等原因,常使橡套电缆局部遭受损坏,从而造成直接或间接的漏地,使供电网路绝缘下降,甚至检漏继电器无法投入运行,影响采区正常供电,给安全生产造成威胁。 71年开始,我们开始使用应急冷补的办法修复受损的橡套电缆。一、材料及来源: 1、混合氯丁胶水。 2、列克纳胶(JQ—1),学名三苯甲烷聚异氰酸酯,大连染料厂和四川长寿化工厂均生产,市场购买或函购均可。 3、胶粉:绝缘橡胶细粉,粉末较细为好。可找就近橡胶厂加工或自制工具用废绝缘橡胶
Rubber cables used in coal mines often cause local damage to the rubber cables due to smashing, scraping, car crowding, roof shed repairs and other causes, resulting in direct or indirect leakage to reduce the insulation of the power supply network, Even leak detection relay can not be put into operation, affecting the normal mining area power supply, to threaten the safety of production. Beginning in the 71 years, we started to use the emergency cold patch repair damaged rubber cables. First, the material and source: 1, mixed neoprene glue. 2, Lexmark (JQ-1), the scientific name of triphenylmethane polyisocyanate, Dalian Dye Factory and Sichuan Changshou Chemical Factory are produced, the market can buy or mail order. 3, rubber powder: insulating rubber powder, fine powder as well. Can be found near the rubber factory processing or self-made tools used insulating rubber
