The procedure of the bonding process :: surface treatment For different types of adherends and different conditions, surface treatment. Strict can be divided into general methods, chemical methods and physical methods. In the decoration industry, simple processing is mainly performed on adhered objects. Such as: dust, oil, rough surface, moisture and other aspects to be treated to ensure that the adhered surface is clean, dry and free of oil.
The glued surface to be glued should be evenly glued to ensure wetting, to avoid the generation of air bubbles as much as possible, and the adhesion strength is greatly reduced due to air holes, which will cause degumming. Attention should be paid to the alignment position once. It should not be shifted. It can be pressurized to remove air and make it in close contact.
The process of curing an adhesive to make its adhesive layer solid through chemical and physical action. Curing is the last step to obtain adhesive properties, which has a great influence on the adhesive strength. During the curing process, temperature, pressure and time are the 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). When applying a certain pressure, it should be said that it is necessary for all adhesives, because pressurization is conducive to the diffusion and penetration of the adhesive, and it is in close contact with the adherend. The layer is uniform and the position of the adherend is fixed. Regardless of whether the chemical reaction or physical action is used to complete the curing of the adhesive layer, a certain amount of time is required. In order to fully obtain the maximum bonding strength, sufficient curing time must be ensured. To reach the final adhesion).
