许多煤矿的强力胶带硫化接头使用一段时间后,经常会出现鼓包问题。通过多次割开鼓包接头查看,发现主要原因是钢丝绳与胶不粘合或是粘合强度过低,导致硫化接头在使用一段时间后鼓包,若不及时发现并停机重新硫化,很容易引起断带事故。通过多次试验分析,发现可能有以下几种原因:①钢丝绳生产厂家在生产胶带时,钢丝裸露在空气中时间太长,钢丝绳表面镀锌层氧化严重;②硫化接头
Bursting problems often occur after a period of use of the strong tape vulcanization joints in many coal mines. By repeatedly cutting the bulge connector to see and found that the main reason is the wire rope and glue is not adhesive or bonding strength is too low, resulting in vulcanized joints in use after a period of bulging, if not found and stop re-curing, it is easy to cause broken With accident. Through many tests and analysis, it is found that there may be several reasons as follows: ① When the wire rope manufacturer produces the adhesive tape, the time during which the steel wire is exposed to the air is too long and the galvanized layer on the surface of the wire rope is seriously oxidized; ② The vulcanized joint
