众所皆知,欲将某一物体分成两个部份,需施加一个足够大的破坏力。同样,要想将两个物体的界面粘附在一起,也需一个足够大的粘结力。这个力就是分子间的作用力,其大小与分子的结构性质有关。对于极性材料如PVC等,一般可用具有亲和性的溶液粘合剂粘合。但对于非极性表面的PP、PE等热塑性塑料,则不能直接用溶液粘合剂粘合,而是要选用具有亲和性的玻璃纤维表面处理剂和热熔粘合剂粘合,也可用热晕和接枝等其它方法粘合。溶液粘合剂大多数是由几种不同的树脂配制混合而成。这种粘合剂常被热熔粘合剂所取代,因为热熔粘合剂操 As we all know, want to be an object divided into two parts, need to impose a large enough destructive power. Also, to adhere the two objects’ surfaces to each other requires a large enough cohesion. This force is the intermolecular force, its size and the molecular nature of the structure. For polar materials such as PVC and the like, it is generally possible to bond with an adhesive solution having affinity. But for the non-polar surface of PP, PE and other thermoplastics, you can not directly with the solution adhesive bonding, but to use affinity with the glass fiber surface treatment agent and hot melt adhesive bonding can also be used Thermal halo and grafting and other methods of bonding. Solution binders are mostly made by mixing several different resin formulations. Such adhesives are often replaced by hot melt adhesives because of hot melt adhesives
