Is the extruded board of melt-blown cloth machine peeled?

1. Improve stickability.

Because the ordinary skin of the extruded board is smooth, it has poor adhesion to the surface mortar and adhesive, so it needs to be peeled to improve its adhesion.

2. Improve system cohesion.

After the extruded board is processed, it also needs to be peeled, so that the roughness of the skin of the sheet is conducive to pasting, greatly improving the tensile bonding strength of the mortar and adhesive, and at the same time, it can also increase the frost resistance and the strength of the sheet. Water resistance strength greatly improves the cohesive force of the system.

3. Release internal stress.

The purpose of peeling the extruded board is also to release a certain amount of internal stress, so that it can avoid the internal quenching of the board in long-term application, thereby reducing the insulation performance of the board and affecting the normal use of the board.
