What does the kind of fire prevention board have? What is the material itself?Issuing time:2021-03-06 13:45 Fire prevention board is the calcium silicate board that we often say namely, calcium silicate board is with natural plant fiber to enhance material, silica is qualitative, calcium is qualitative main body material, through advanced technology is formed, pressure, high temperature steam raises wait for special technology processing and make, it is a kind of new-type building materials of environmental protection that has excellent performance. Calcium silicate board according to the material is divided into: asbestos calcium silicate board and no asbestos calcium silicate board. Asbestos is harmful to human body, so everyone in the choice of calcium silicate board recommended to buy calcium silicate board without asbestos. So how to choose asbestos-free calcium silicate board? The presence of asbestos can be determined by burning. Calcium silicate board is fire board, direct fire complete board without any effect. Before ignition, must use a method to cut off the plate, pay attention not to use the chain saw to cut directly. If it's thin, cut it directly with your hands. If it's thick, cut it with a hammer. When you break it down, you'll find that the cross section is covered with little lines, either asbestos or plant fibers. If it is asbestos, the burning will announce a big impact on the smell of burning, if it is plant fibers, after burning will announce the taste of burning paper. It is easy to tell if the calcium silicate plate is rich in asbestos by smelling it. You can see the appearance of the calcium silicate plate. You can look at the side of it and see if there are a lot of little white dots on it, which are asbestos. The length of the calcium silicate board is 2440mm, the width is 1220mm, the thickness of the calcium silicate board is between 5-24mm, and according to the needs of customers, you can cut freely. Non-asbestos calcium silicate board for A1 grade non-combustible material, the board waterproof performance is excellent. Plate acid and alkali resistance, not easy to corrode, not damp and insect ant damage, can ensure a long life. The insulation performance of 20 mm thick partition wall is obviously better than ordinary brick wall, sound insulation effect is pretty good. |
