Common problems in PVC foam board and its solution
The use of PVC foam board is very wide, and its price is very low. It has always been popular with consumers. However, there are still some problems in the use of PVC foam board. Here, the editors of Xingang PVC Foam Boards and their friends explain the common problems and their solutions.
1, the board yellow
In the process of processing, because the temperature is too high or the stability is insufficient, it is easy to cause yellowing of the board surface, thereby affecting the appearance of the PVC foam board. Therefore, when processing, we need to control the processing temperature, for example, to reduce the temperature. If you still find that the situation has not improved, you need to add some stabilizers and lubricants.
2, curved board
When the board is bent, it is because the flow is uneven or the cooling is not in place. Therefore, when cooling, it must be ensured that the cooling is even and in place. At the same time, it is necessary to adjust the flow conditions.
Among them, the common problems in the PVC foam board include yellowing in the middle of the board, foaming or foam delamination in the cross-section, uneven thickness of the board, changes in the thickness of the board, etc. Therefore, we must pay special attention to this issue during processing.
