LW-1000A丝扣脂在高温螺纹副上的适用性考察

Applicability Investigation of LW-1000A Thread Grease on Elevated Temperature Thread Pair

研究了用润滑脂来解决高温(700℃～1000℃)螺纹副拆卸困难的问题。对LW-1000A丝扣脂的高温抗粘结性能,高温抗腐蚀性能和自锁力矩进行了适用性考察。涂抹了LW-1000A丝扣脂的螺纹副拆卸顺利,LW-1000A丝扣脂对螺纹副没有腐蚀,对螺纹副的自锁力矩也没有影响。将LW-1000A丝扣脂涂抹在高温螺纹副上,可以解决高温螺纹副的拆卸难题。

The problem of using grease to solve the difficulty of disassembling elevated temperature thread pair （700 ℃ to 1000 ℃） was studied.The applicability of elevated temperature anti-bonding property,elevated temperature corrosion resistance and self-locking torque of LW-1000A thread grease was researched.The thread pair that smeared with LW-1000A thread grease was disassembly smoothly.LW-1000A thread grease did not corrode threads and had no influence to the self-locking torque of thread pair.The LW-1000A thread grease was applied to elevated temperature thread pair could solve the disassembly problem of elevated temperature thread pair.
