螺纹锁固用厌氧胶的评价指标和应用特点

介绍了螺纹锁固用厌氧胶的密封原理,总结了厌氧胶的常用评价指标(扭矩、固化速率、耐热温度和黏度等)及现有厌氧胶的种类与性能(包括乐泰厌氧胶、GY系列厌氧胶、J系列厌氧胶和其他厌氧胶产品),并讨论了厌氧胶的清除技术(包括螺纹件的拆卸、残余厌氧胶的清除等)。最后展望了厌氧胶的发展方向。

Evaluation indexes and application characteristics of anaerobic adhesive for thread-locking

The sealing principle of anaerobic adhesive for thread-locking was introduced,the common evaluation indexes(such as torque,curing speed,heat-resistant temperature,viscosity,and other indexes) of anaerobic adhesives,and the types and properties of existing anaerobic adhesives(including Loctite anaerobic adhesives,GY series of anaerobic adhesives,J series of anaerobic adhesives and other anaerobic adhesives products) were summarized.And the removal technology(including disassembly of screw elements,removing residual anaerobic adhesive) of anaerobic adhesives was discussed.Finally,the development directions of anaerobic adhesives were expected.
