When it comes to the selection of PVC foam boards, we all want to choose products with good performance, so that we can play a better effect in actual use. This requires us to perform a test on its quality. If a product of average quality is selected without testing, it will affect the normal use effect. Let's take a look at how to detect it.
1. The surface of the PVC foam board should be smooth and flat, mechanical texture is not obvious, no color difference on the surface, milky white, no stain on the surface, no obvious pits, no pinholes, no coarse holes, cracks. Note: Non-creamy foamed board penetrates into the recycled waste board, which is not an environmentally friendly board. The environmentally friendly board does not contain lead (the content is less than European and American standards).
2. The side of the PVC foam board should be flat incision, fine pores, no pinholes, no large perforations, no serious powder loss, no bee holes, and the open fibers will fall off automatically and not pop. Note: Pay attention to the above situation, and it is troublesome to do the finished product in the subsequent sequence.
3. The thickness of the PVC foam board should be measured with a caliper and placed on the surface, the contact is tight and seamless, and the thickness is uniform on the left and right.
