在螺栓的螺纹处现场涂敷厌氧胶,然后将螺纹拧紧,待胶液固化后厌氧胶形成一定的粘接强度,可以有效地防止螺纹松动。采用这种现场涂胶的方式防止螺纹松动较为便捷,防松效果明显,因此在工程机械上使用较为普遍。但现场涂胶方式也存在诸如锁固胶胶液浪费量较大、涂胶不规范、螺纹处涂胶量大小不好控制等问题。而预涂干膜锁固胶技术的出现,很好地解决了上述问题。 Apply anaerobic glue on the thread of the bolt, and then tighten the thread until the glue becomes solidified to form a certain adhesive strength, which can effectively prevent the thread from loosening. The use of this on-site glue way to prevent loosening screw is more convenient, anti-loose effect is obvious, so the use of construction machinery is more common. However, there are also on-site gumming methods such as locking glue fluid waste larger, non-standard glue, glue the amount of glue at the size of poor control and other issues. The pre-coated dry film glue technology, the emergence of a good solution to the above problems.
