几乎所有工厂生产的产品都由各种零部件组合而成，而这些零部件又需要通过不同的方式进行固定和连接。在产品的装配过程中，除了机械紧固（螺钉、铆钉、焊接和过盈连接等）以外，使用胶粘剂是另一种不同重要的手段。

Almost all products produced in factories consist of various parts, which in turn need to be fixed and connected in different ways. In addition to mechanical fastening (screws, rivets, welding, interference joints, etc.), the use of adhesives offers another important means in the assembly of products.

胶粘剂通过粘附作用使零部件结合在一起，它以液体、薄膜或膏状形态存在。相比机械方式，使用胶粘剂有很多优点，例如：

Adhesives bind parts together by adhesion and are available in liquid, film, and paste forms. The use of adhesives has many advantages over mechanical means, such as:

• 可以有效地应用于不同种类的金属或非金属材料之间的粘结（金属、塑料、橡胶、陶瓷、软木、玻璃、木材、纸张、纤维等各种材料），而机械固定难以实现。

It can be effectively applied for bonding between different kinds of metallic or non-metallic materials (metal, plastic, rubber, ceramic, cork, glass, wood, paper, fiber, and various other materials), which is difficult to achieve by mechanical fixing.

• 胶粘剂均匀地分布于粘接面，能够大面积传递载荷，没有点焊、螺栓连接或铆接所存在的应力集中问题。这点非常重要，因为从重量和成本上面考虑，基材可以被制造得更薄。

The adhesive is evenly distributed on the bonding surface, enabling the transfer of loads over a large area without the stress concentration problems that exist with spot welding, bolting, or riveting. This is very important, because this way the substrate material can be made thinner for weight and cost reasons.

• 粘接件中的粘结缝隙具有对水、空气或其它环境介质的优良密封性，这是机械连接所不具备的。

The bonded seam in the bonded part provides an excellent seal against water, air, or other environmental media, which is not available with mechanical joints.

• 在一些起装饰作用的板材上，胶粘剂的使用能够避免出现机械连接中出现的铆钉或者螺栓头突出的情况，从而使连接件更加美观。

In some decorative plates, the use of adhesives can avoid the protrusion of rivets or bolt heads that occur in mechanical joints, thus making the joint more aesthetically pleasing.

胶粘剂根据分子结构可以有多种不同的分类，这些类别有不同的优缺点和应用领域：

Adhesives can be classified into many different categories according to their molecular structure, and these categories have different advantages, disadvantages, and areas of application:

胶粘剂由于其优异的特性，日常广泛应用于包括航空航天、建筑、汽车、包装以及机械电子等工业领域。粘合剂为这些领域中的产品上的零配件的粘接、密封以及固定上起到了非常重要的作用。

Due to their excellent properties, adhesives are used daily in a wide range of industries including aerospace, construction, automotive, packaging, and mechanical and electronic applications. Adhesives play an important role in bonding, sealing, and fixing parts of products in these fields.
