本文概括介绍了粘接技术、胶粘剂的发展现状,粘接的原理及其特点、粘接工艺和在设备维修应用中所取得的技术、经济效果。并认为粘接技术在发展应用的过程中还有许多问题有待进一步开发研究、试验和总结。粘接技术的理论目前有机械联结理论、吸附理论、扩散(互溶)理论、静电理论和化学键结合理论等,这些理论尚不能对生产实践起全面的指导作用,须进一步深入研究;在维修应用中,对重要的零件粘接,其接头结构设计、被粘表面的处理、胶种选择等尚未规范化;胶粘剂的性能(如强度、耐高温性、耐老化性
This article summarizes the bonding technology, the development of adhesives, bonding principle and characteristics, bonding technology and equipment maintenance applications made in the technology, economic effect. And that the adhesive bonding technology in the development and application of the process there are many issues to be further developed research, testing and summary. At present, there are theories of bonding technology such as mechanical coupling theory, adsorption theory, diffusion (mutual solubility) theory, electrostatic theory and chemical bonding theory. These theories can not give a comprehensive guide to production practice and need to be further studied. In the application of maintenance , The bonding of important parts, the structure design of joints, the treatment of the surface to be glued, selection of plastic species, etc. have not yet been standardized; the properties of the adhesive (such as strength, high temperature resistance and aging resistance
