随着高分子化学的发展,已经生产了不同类型的热固性和热塑性的合成树脂型、橡胶型、树脂-橡胶混合型以及无机型等胶粘剂。它可以部分代替铆接、焊接或机械装配,还可以使无法焊接的极薄极硬的金属、非金属以及形状复什的构件牢固地连接在一起。胶接部分的应力分布均匀,不仅具有足够的抗拉强度,而且具有绝缘及耐腐蚀性能,也可用作密封材料。胶粘剂的成本低廉、操作工艺简便。最近,就上海地区的汽轮机、电机、农机、机床、仪表和造船等25个单位的胶粘剂应用情况作了调查,证明胶粘剂在机械工业有着广泛的用途,经济效果显著。例如二千吨油压机
With the development of polymer chemistry, different types of thermosetting and thermoplastic synthetic resin, rubber type, resin-rubber hybrid type and inorganic type adhesives have been produced. It can be partially replaced by riveting, welding or mechanical assembly, but also can not weld extremely thin hard metal, non-metallic and shape of the components connected together firmly. Adhesive part of the stress distribution, not only has sufficient tensile strength, but also has insulation and corrosion resistance, can also be used as a sealing material. Adhesive low cost, easy operation. Recently, a survey was conducted on the application of adhesives in 25 units of steam turbines, motors, agricultural machines, machine tools, gauges and shipbuilding in Shanghai, proving that the adhesives have a wide range of applications in the machinery industry with remarkable economic results. For example, two thousand tons hydraulic machine
