Polystyrene particles sandwich board composed of material from natural vermiculite, high-purity quartz powder, inorganic fiber and plant fiber by high temperature, high pressure steam curing is made, the decision he has good thermal insulation function, let your interior environment more comfortable. Polystyrene particles sandwich with climate change with the seasons and the ability to automatically adjust the indoor air moisture content, so humidity is kept constant for a horizontal, light wall panels, to achieve ecological regulation effect, in line with the development trend of modern residential buildings. Experiments show that polystyrene particles in the absence of sandwich panels can make any waterproof finishes with cement bonded into a pool filled with water body, the back wall can be kept dry, lightweight partition MILL, leaving no trace, In wet weather, it will not appear condensate water drops. Wallboard panels are professional water board, have a good waterproof, moisture resistant, lightweight partition board density, suitable for kitchens, bathrooms, basements and other damp areas. Polystyrene particles sandwich board surface and internal composition of cement fiber materials have good sound insulation effect, 90mm thick wallboard amount of noise 43dB, its acoustic effects in line with the requirements of national housing insulation, significantly higher than other bricks Wall of sound insulation.
