中国烟台引进美国LOCTITE厌氧胶技术生产的乐泰厌氧胶,经我们在设备修理中多次使用,收到较好的效果。乐泰厌氧胶种类很多,乐泰(中国)厌氧胶按其作用不同可分为: 1、螺蚊锁固胶,用于螺纹防震防松。 2、密封胶,可以代替纸垫、垫片等起密封作用。 3、机件固持胶,如轴承、轴承磨损,用固持胶填补和固持磨损造成的间隙和松动。 4、粘接和密封其它材料,如各类金属、玻璃、陶瓷、磁铁等。我们首次使用的乐泰厌氧胶是609固持胶。我公司生产车间在检修5吨天车故障时,发现电机轴与滚动轴承配合部位严重磨损, 相似文献

一种新型厌氧胶专用清除剂清除效果的研究 总被引:1,自引:0,他引:1
研究了一种新研制的厌氧胶清除剂的清除效果。在常温下,用这种清除剂浸泡经不同品种厌氧胶粘接过的铜制和不锈钢螺栓连接件,30rnin即可以达到97%以上的清除率。并借助于扫描电镜观察浸泡前后的HTO42胶层的微观形貌,证实在浸泡前表面结构致密的胶层浸泡后结构变疏松,表明该清除剂对胶层有较好的溶胀和溶解作用,是一种在短时间内就能达到清除效果的低毒性通用型厌氧胶专用清除剂。 相似文献

Hybrid adhesive joining techniques are often used in many industrial sectors to design lightweight structures. A hybrid adhesive joint results from the combination of adhesive bonding with other traditional joining methods such as welding and mechanical fastening, with the aim of combining the advantages of the different techniques and overcoming their drawbacks.This study focuses on the interference fitted/adhesive bonded joining technique. In this application, two cylindrical components are coupled together by inserting one into the other, after having placed an adhesive between them. Generally anaerobic acrylic adhesives, also known as “retaining compound” are used for this application. However the effect of the adhesive nature and of its mechanical and adhesive responses on the performance of the hybrid joint is still unclear. The aim of the present research is to improve the understanding of the behaviour of different adhesives, including rigid epoxies and flexible polyurethanes, in the presence of an interference-fit. Static strength of bonded and unbonded interference fit joints have been compared in order to investigate the role of the different adhesives. 相似文献

We have synthesized dimethacrylates of diallyl-, di(prop-1-enyl)-, and dipropyl bisphenol A by reacting the corresponding sodium phenoxide with methacryloyl chloride. The purified monomers were characterized by IR, 1H-NMR, and mass spectrometry. A number of anaerobic adhesive formulations were made using these monomers. Tensile shear, impact, and torque strengths of the anaerobic adhesive bonds were measured by ASTM standard methods to evaluate the performance of these adhesive compositions. Generally they performed much better as anaerobic adhesives over conventional anaerobic adhesive formulations based on polyethyleneglycol dimethacrylates. 相似文献
