To sum up, the following points should be noted during construction:
-
Bonding process procedures: Surface treatment varies according to the nature of the adherends and different situations. Strictly speaking, it can be divided into general methods, chemical methods, and physical methods. In the decoration industry, simple treatment is mainly carried out on the adherend objects. For example, deal with dust, oil stains, rough surfaces, moisture, etc., to ensure that the adherend surface is clean, dry, and free of oil stains.
-
Glue application: The adherend surface should be evenly coated with glue to ensure wetting and avoid air bubbles as much as possible. The presence of pores can greatly reduce the bonding strength and lead to debonding. It should be noted that the position should be aligned accurately at one time without misalignment. Pressure can be applied to expel air and make them come into close contact.
-
Curing: Curing is the process by which the adhesive layer of an adhesive turns solid through chemical and physical actions. Curing is the final step in obtaining bonding performance and has a significant impact on the bonding strength.
During 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.) Applying a certain pressure during curing is necessary for all adhesives. This is because applying pressure is conducive to the diffusion and penetration of the adhesive, enabling it to come into close contact with the adherend, helping to expel gas and moisture, and avoiding the formation of bubbles and pores, thus making the adhesive layer uniform and fixing the position of the adherend.
Whether the curing of the adhesive layer is completed through chemical reactions or physical actions, it requires a certain amount of time. To achieve complete curing and obtain the maximum bonding strength, sufficient curing time must be ensured. (This is what is usually referred to as allowing a certain amount of time for the adhesive to reach its ultimate adhesive force.)
