1.Familiar with the properties of adhesives For bonding, adhesive is the basis, the selection of adhesive, its performance is an important basis. Different types of adhesives, with different properties, determine their various uses, only familiar with the performance of adhesives, in order to handy selection. 2.Identify the nature of the adhesive There are many types of adhesive species with diffe...
The adhesive not only needs it to stick firmly, but also needs long-term viscosity, the effect of the adhesive is better, if it can not be sustained, after a period of time it will fall off, or for some reason, the viscosity will decline, so we sometimes need to think of some ways to ensure the durability of the viscosity. Research work and experience have shown that adhesives can bond things by i...
