Extruded board in the processing and production, also need to go to the leather processing, only after the application installation, to deal with the skin is very necessary, ordinary skin smooth, and as well as the adhesive plaster mortar paste sex is very poor, so need to go to the leather processing, then introduce extruded board to deal with the skin.
Improve the bonding force of the system
After extruded board processing, also need to go to the leather processing, for this link has two main purposes, the first purpose is to make the plate surface roughness is beneficial to paste, and greatly improve the plaster mortar adhesive tensile bond strength, at the same time, also can improve the resistance to freezing of sheet strength and water resistance strength, greatly improve the bonding force of the system.
Second, release internal stress
Extruded board to deal with the skin of the second goal is to release a certain amount of internal stress, so can effectively avoid the plank appear in long-term application of internal quenching is broken, thus reducing board insulation sheet and affect the normal use.
