Shandong takeoff Decoration Engineering Company Limited (#) is located in Tai'an City, Shandong Tai'an triple drum stone street in the village on the 2nd commercial and residential on the 2nd, Contact: Lee foam insulation board is currently cement wall insulation and wall insulation Fire Barrier with the best insulation materials, its advantages are: low thermal conductivity, thermal insulation effect is good thin stone one board manufacturers, does not burn, waterproof, strong bond with the wall, high strength, non-toxic radioactive substances, and environmental protection. With the same period in the life of the building, and the construction is simple and fast. Technical performance is better than foam glass, ceramic foam, phenolic foam board, polystyrene particles, polystyrene board, extruded sheet and other wall insulation materials. How to determine the quality of marble slabs of marble is the role of the natural formation of the earth's crust millions of years, and it hard material, in the general situation of life of up to a few decades or even centuries. Selection of marble, from the color, pattern, capillary water absorption, hardness, etc. into account. Let's look at how to determine the specific quality marble: 1, in the purchase of marble stone by hand percussion test firmness, knocking marble surface, listening to its sound, feel touch, if the quality of sturdy stone the sound is crisp and solid feel to issue one national sales thin stone plate to avoid cracks in the stone house to pick minor presence. 2, the stone surface structure was visually observed, the finer particles are more representative of the quality is good. 3, the structure of the surface if cracks are calcium silicate board stone one board, the future risk of stone have easily broken one plate, on the performance of the texture of the stone Omo who are not very beautiful. These are a few ways to judge the quality of marble, hoping to bring more knowledge to give customers some help, if in doubt, keep an eye on our website to ensure you have a windfall.
