随着高分子材料的发展,结构粘合剂性能不断得到提高,品种类型愈益繁多,使用也越来越广泛。它在航天军工等领域中的应用从效率和成本上看要优于软焊、焊接和机械连接,但使用成功与否,对粘合剂典型特性的了解和粘合剂使用类型的选择以及选择标准的确定具有重要意义。文章介绍了粘合剂分类、选择标准,并对多种粘合剂的典型性能、优缺点、使用局限性作了扼要的评价。
With the development of polymer materials, the performance of structural adhesives has been continuously improved, more and more varieties of types, the use is also more and more widely. Its use in aerospace and defense industries is superior to soldering, soldering and mechanical joining in terms of efficiency and cost, but the success or failure of the application, the knowledge of the typical properties of the adhesive, the choice of the type of adhesive to be used and the choice The standard is of great significance. This article introduces the classification of adhesive, selection criteria, and briefly reviews the typical performance, advantages and disadvantages, and limitations of various adhesives.
