Procedure of bonding process: Surface treatment: Surface treatment is carried out for different properties of adherends and different situations. Strictly can be divided into general methods, chemical methods and physical methods. In the decoration industry, simple treatment is mainly for the adhered objects. Such as: dust, oil, rough surface, moisture, etc., to ensure that the sticky surface is clean, dry and free of oil.
The glued surface should be glued evenly to ensure infiltration, and avoid bubbles as much as possible. Due to pores, the bonding strength will be greatly reduced, resulting in degumming. It should be noted that the position should be aligned once, not to be moved, but to pressurize and remove the air to make close contact.
Curing adhesive is a process in which the adhesive layer becomes solid through chemical and physical action. Curing is the last step to obtain bonding performance and has a great influence on bonding strength. In the curing process, temperature, pressure, and time are three important parameters of the curing process. The change of each parameter has a direct impact on the bonding strength. (Each adhesive has a specific curing temperature and time). It should be said that a certain amount of pressure is necessary for all adhesives, because pressure is conducive to the diffusion and penetration of the adhesive, and it is in close contact with the adherend, which helps exhaust gas, moisture, and avoids bubbles and pores. The layer is uniform and the position of the adherend is fixed. Whether it is by chemical reaction or physical action to complete the curing of the adhesive layer, it takes a certain amount of time. In order to fully obtain the maximum bonding strength through the curing, sufficient curing time must be ensured. (This is usually a certain time for the adhesive Reach the final viscosity).
