PVC crust foam board business standards or national standards

Answer:

Received, PVC crust foam of the enterprise standard can not send me a ah? I also find the national standard did not.
PVC leather crust GB national standard building templates have not yet issued, at present only the standard, wood-plastic architectural template
The true crust is made with a stoppage method, which forms a layer of dense hard crust on both sides of the sheet, which can improve the hardness and nail force of the plate. These physical properties are very important for the manufacture of furniture or for the decoration of the house. To identify the PVC board is (really) crust, in fact, very simple! As long as the shop does not pay attention to the thumb with the nail on the PVC board pressure, and then carefully check whether there is a deep dent, if there is, is clearly false, it is best not to. Celuka (Celuka) also known as controlled foam method, the current application is very wide, by the French gine kulmann company invented, it is the first patented one of the extrusion foam molding method. The principle of the Luca method is that the outer skin of the melt is compressed and cooled in the styling device directly connected to the die, and the mandrel in the cavity ensures that there is room left when the extrudate leaves the die Through the melt in the mold within the free foam is filled. Cooling strength, core mold size, extrusion speed, can affect the foam core layer density and outer crust thickness. The complex shapes of the profiles produced in this way have the characteristics of low density, high hardness and smooth surface. Baotian Hi-Tech can visit, in addition to their production of PVC crust foam board, but also the production of PVC own foam board, PVC foam profiles, product quality is in the high-end.
