In fact, the production process of extruded boards is not very complicated, but in order to ensure that the processed boards can meet customer needs and can be used for a long time, the manufacturers of extruded boards need to pay more attention to the production process of boards. Next, we will introduce the precautions in the production of extruded boards.
1、 Pay attention to extrusion process
Extrusion board is made by extrusion process. Effective control of this link can realize the quality control of the board.
2、 Add flame retardant
Extruded board is a kind of combustible board. Therefore, flame retardant must be added in the production process. The state has also issued a corresponding policy, and non flame retardant boards are not allowed to go on the wall.
3、 Peeling treatment
In the production process of extruded boards, attention should also be paid to peeling. The main purpose of this process is to improve the bonding force of the whole system and release the internal stress.
1. Improve system adhesion
After the extruded board is processed, it also needs to be peeled. There are two main purposes in this process. The first is to make the surface roughness of the board conducive to pasting, greatly improving the tensile bonding strength of the plastering mortar and adhesive. At the same time, it can also improve the frost resistance and water resistance of the board, greatly improving the bonding strength of the system.
2. Release internal stress
The second purpose of peeling extruded plates is to release a certain amount of internal stress, which can effectively avoid the internal quenching of the plates in long-term application, thus reducing the thermal insulation performance of the plates and affecting the normal use of the plates.
