The hylam sheet is the adhesive board we often say, the academic name phenolic laminating cardboard, this kind of material is made from the phenolic resin which is made from the high purity, all synthetic petrochemical raw material as the resin adhesive. We can’t judge the hylam sheet like wood board, although there are “wood board” in the hylam sheet, but the wood board is just two different materials. The method of judging the quality is different naturally. Then we can see how to judge the quality of the wood board.
1. first of all, we should understand the transparency of the hylam sheet. The good quality of the wood board needs to reach about 94%. The lower the transparency, the more the recycled materials are added, and the color of the poor quality wood board is darkening.
2. can see the thickness of the plate, the thicker, the material is more foot, the higher the proportion, the cost is high, the quality of the plate is better, this method is also known as the unit area of the weight of the weight of Hibiscus. Open the protective film carefully to look at the surface of the plate. The plate without impurity particles is brand new. The more impurities the recycled material is added, the more obvious the quality of the plate is.
3. take a block of wood plate, bending test, if easy to brittle fracture, the plate quality is very poor, polycarbonate is the main raw material for the production and processing of hylam sheet, is a kind of high strength, light transmission, sound insulation, energy saving new quality decoration materials widely adopted at present.
On the judgment of the quality of the wood board, we will introduce here, if you have any questions or demands on the processing of the FR-4 fiberglass board (yellow halogen free, white halogen, white halogen), Teflon, acrylic and various non-metallic materials, welcome you to call, or come to the factory to discuss and negotiate.
