Bonding process for the surface treatment process :: different types of adherends and different situations, a surface treatment. Strict general method can be divided into chemical and physical methods. In the decoration industry, mainly for simple treatment is adhered object. Such as: dust, oil, matte, water and other aspects of treatment to ensure adhesive surface is clean, dry and free of grease.
Glue sticky surface should be uniform coating, in order to ensure infiltration, as far as possible to avoid air bubbles, because there are holes leaving adhesive strength declined significantly, leading unglued. It should be noted once aligned position, dislocation can not be pressurized, air is excluded, so that close contact.
Curing adhesive by chemical and physical effects that make a solid layer change process. Curing is the last step to obtain adhesive properties, the impact on the adhesion strength is great. During the curing process, the temperature, pressure and time are three important parameters of the curing process, the changes have a direct impact on the adhesion strength of each parameter, (each adhesive has a specific curing temperature and time), curing when a certain pressure is applied, it should be said for all adhesives are necessary because the pressure conducive to the spread adhesive penetration into close contact with the adherend to help exhaust gases, moisture, avoid air bubbles, leaving voids gum uniform layer and adherend fixed position. Either by chemical reaction or physical action to complete the cured adhesive layer, need some time to get completely cured maximum bond strength, must ensure that sufficient curing time, (which is usually referred to a certain time so that the adhesive to reach the final tack).
