adherend

Study on surface pretreatment of titanium alloy adherend

钛合金粘接件表面技术研究

Water-based polymer combined adhesive has the feature of environment-friendly, low cost, formula designability and good adaptability to adherend materials.

水性高分子复合型胶粘剂具有环保性、配方的可设计性、对被胶接材料的胶接适应性强、成本相对低廉等特点。

It also showed the thicknesses of adherend and mid-bondline influenced the strength of joint greatly.

对接头强度影响较大的两个因素为胶层厚度和被粘物厚度；

The bonding results are related to the interface characteristics of the adhesive and the adherend.

粘接效果与参与物质的界面性质有关。

The strength decreases with the shorter distance between the clamps, increases with the increasing of the adherend thickness, but the increase is not unlimited.

另外，胶结强度随夹具之间的距离变短而降低，随被粘物厚度的增大而增大。

It is clear that increases adherend thickness or Poisson ratio as well as decreases the elastic modulus may decrease the peck value of Von Mises equivalent stress.

分析可知：高的泊松比、低弹性模量和被粘物厚的增大会使得VON MISES等效应力值显著降低。

The bonding results are related to the interface characteristics of adherend.

粘接效果与参与物质的界面性质有关.

The stress and strain distributions in the gluing joint are considerably influenced by some factors such as the geometry of the adherend, the lap length and the adhesive thickness etc.

胶接接头中应力应变分布的具体情况取决于被粘物的几何尺寸、搭接长度以及胶层厚度等因素。

A three-dimensional transition region exists between the bulk adhesive and the adherend, and this region is referred as the "interphase".

前言：在胶粘剂基体和被粘材料之间存在着一个三维转变相区，这一相区被称为界相。

When the adherend is soaked in H2O, 3% HCl, 3% NaOH for 150h, shedding quantity of powder respectively is: ≤ 0.03%,≤ 0.07% and ≤ 0.04%.

粘接体系分别在水、3%盐酸溶液和3%氢氧化钠溶液中浸泡150h以上，其粉粒脱落量分别≤0.03%、≤0.07%和≤0.04%。
