How To Test PVC Skinning And Foaming Template
May 17, 2022
PVC skinning foam template is a practical material. Because its main chemical composition is PVC, it is also called foam PVC board. It can be seen in the interior decoration of the car roof or some buildings. The popular PVC skin foam template has many advantages such as waterproof, heat preservation, sound insulation and heat resistance. So how do we pass the performance? How to choose a reliable PVC skin foaming template?
1. Detection of PVC skinning and foaming template
When testing the board surface of PVC skinning and foaming template, first touch the surface with hand to see the smoothness of hand feeling and the fineness of mechanical texture, and at the same time, see whether there is color difference on the board surface. The normal color of the board surface is milky white and the surface is free of stains, pits, pinholes and holes, and there is no crack.

2. Side detection of PVC skinning foaming template
In addition to the detection of the board surface of PVC skinning and foaming template, the side edge of PVC skinning and foaming template should also be tested. When testing the side edge of PVC skinning and foaming template, the flatness of the incision and the fine density of the pores should be considered. In the process of testing the side of the board, it should be ensured that there are no pinholes, no coarse pores, and no obvious powder loss. At the same time, it should be determined whether the opening fiber falls off and collapses In the detection process, the above problems will cause great trouble to the subsequent processing of finished products.
3. Detection of thickness, weight and density of PVC crust foaming template
In addition to the appearance inspection of PVC skinning and foaming formwork, the thickness, weight and density of the formwork shall also be inspected. When the thickness is inspected, the caliper shall be cubic and close to the board surface, without any gap. The thickness of the Board shall be uniform in the left and right, and the thickness deviation shall not be controlled within a reasonable range. When the weight and density of the board are inspected, it shall be firmly remembered The calculation formula of weight and density ensures the accuracy of measurement data.
