What is the reason for the deformation of the surface of the PVC foam board? How to solve?
I believe that many people have encountered the situation of deformation of the surface of PVC foam board. When the phenomenon of board surface deformation occurs, what should we do? First of all, we must know what causes this phenomenon, so that we can prescribe the right medicine to prevent the next time. So let's find out why.
The reason for the deformation of the surface of the PVC foamed board is that the cooling rate on both sides is inconsistent and the cell structure is not uniform.
Adjust the cooling temperature and cooling rate on both sides and homogenize the cell diameter.
