The procedure of bonding process: Dolomite sand surface treatment For adherends of different nature and different situations, surface treatment is carried out. Strictly can be divided into general methods, chemical methods and physical methods. In the decoration industry, it is mainly for simple processing of the adhered objects. Such as: dust, oil, rough surface, moisture, etc. are treated, and the adhered surface is clean, dry, and free of oil.

The surface to be glued should be evenly coated with glue to infiltrate and avoid the generation of air bubbles as much as possible. Due to the presence of pores, the bonding strength is greatly reduced, resulting in degumming. Attention should be paid to the alignment position, and it should not be misplaced. It can be pressurized to remove air and make it in close contact. dolomite sand price

The process of solidifying the adhesive layer through chemical and physical action. Curing is the last step in obtaining bond properties and affects bond strength. In the curing process, temperature, pressure and time are the three important parameters of the curing process. The change of the parameters has a direct impact on the bonding strength. (All kinds of adhesives have specific curing temperature and time). The pressure applied at the time should be said to be the same for the adhesive, because the pressure is conducive to the diffusion and penetration of the adhesive, and it is in close contact with the adherend. The sticky position is fixed. Whether it is by chemical reaction or physical action to complete the curing of the adhesive layer, it takes time, in order to fully obtain the adhesive strength obtained by curing, some curing time, (this is usually referred to as the time required to make the final adhesive force of the adhesive).
