表面、界面的作用与粘接机理(一)

Eeffect of surface, interface and adhesion principle (I)

表面、界面的作用,对粘接过程有很大的贡献。本文介绍了材料表面、界面的湿润与吸附作用对粘接的影响,内容包括表面张力与界面张力,接触角,固体材料表面能的测算,湿润与湿润速度,粘附功与粘附界面的稳定性,粘附与吸附作用的对照等。

The effect of surface and interface has a vast contribution on adhesion process. The influence of wetting and adsorbing of material surface and interface on adhesion are introduced in this paper. Its content includes the surface tension and interface tension, contact angle, determination of solid surface energy, wetting and wetting rate, adhesion work and stability of adhesion interface, and the contrast of adhesion and absorption.
