Q: Is the calcium silicate board gypsum board?: No, calcium silicate board and gypsum board is completely different from the two materials, but because of the use of almost, so easy to confuse.

Q: Ceiling, shape the same, with gypsum board is good, or with silicon calcium board material is good: Now on the market, most of the gypsum board is more, no matter where you use, require product performance better Caixing. There is a smallpox is better, is now on the market high-end products - Connolly ceiling

Q: What is the amount of tropicin in the calcium silicate board? Or how to define? What is the effect of the content on the quality of calcium silicate board?: This question is not a direct answer. The toe mullite is mainly composed of cement and quartz sand at high temperature and high pressure, produced in the autoclave. Of course, is a high point, increase the stability and strength of calcium silicate board

Q: What is the difference between aluminum-plastic plate and calcium-plastic plate? How to use it in those places?: As a new environmentally friendly building materials, in addition to the function of the traditional gypsum board, but also has excellent fire performance and moisture resistance, the advantages of long life, a large number of industrial and commercial construction in the ceiling ceiling and partition, home decoration, furniture liner, Billboards, shipboard compartment boards, warehouse floor panels, network floor and tunnel and other indoor works of the wall. Calcium silicate board manufacturing principle is a siliceous material, calcium material in the high temperature and high pressure under the conditions of chemical reaction, resulting in "Toledo to stone" crystal-based calcium silicate. Raw materials are generally quartz sand for the siliceous material; cement, lime for the calcium material; to cellulose fiber as a reinforcing material. Different raw materials and their ratio determines the calcium silicate board products in the "Too Maimai Lai" crystal production number. Silicon content and calcium content of the higher raw materials, the more likely to react to more "Topemi to stone", the better the physical properties of the product. Calcium silicate board may be the best fire performance of the wall ceiling plate.

Q: What kind of ceiling does the open kitchen do? Is it the same as the lobby to do the calcium silicate board, or do it?: Chinese kitchen generally recommended with aluminum slab plate or plastic plate, the most important is practical.

Q: Calcium silicate board surface putty Why crack?: 1, improper handling of deformation joints: in the deformation of the calcium silicate board ceiling no seam, the entire plate directly connected. Although some of the deformation of the seam, but the deformation of the practice is not right, only in the panel at the seam, and the keel is not broken, the deformation of the structure under the action, calcium silicate board is easy to crack. 2, the wall at the junction of improper handling: not in accordance with the requirements of the node set construction, but in the calcium silicate board and the junction of the wall directly with the stopper putty full scraping, and some also use copper tape paste to strengthen, leaving no Shrink the space, causing the crack. 3, improper storage of the plate: the plate in the installation and construction of wet moisture, resulting in deformation, in the natural dry conditions after construction, resulting in shrinkage, cracks. 4, hanging keel installation spacing is too large: part of the keel of the mechanical properties did not meet the national standard indicators, the plate after the installation of a greater degree of deformation. Keel and plate when the connector is not staggered, it is difficult to avoid stress concentration. The whole plate is installed in different directions at the same time on the screw fixation, so that the sub-stress within the plate easy to crack.

Q: Home improvement with cotton calcium silicate board how to do?: If not, for the brand, it is not OK, with gypsum board it, although the moisture-proof fire better, but with some peace of mind. No matter what the material board, as far as possible in the market to cut well, on the one hand is convenient to transport and up and down the elevator convenient, the most important, do not leave cutting dust at home, these cutting dust anywhere in the home can be adsorbed, Will continue to flow out with the air, the decoration of the house although it looks very clean, but there is a confusion is the big dust at home, is the reason. After the installation of the installation, the board of the six sides are made on the closure, first, so that the cutting site is not easy to damp, the second is the board sealed, not because of time for a long time damp, deformation, collapse and yellow.

Q: Why is silicon calcium board not suitable for use in home decoration?: This is from the decoration style, the material is not appropriate, silicon calcium gypsum board to semi-water gypsum and silicone oil as the main material, the surface of the silicone oil with the transport installation will be out of friction, a long time will be depleted Loss, if you run JS, silicone oil coating is not full, then the moisture effect is even worse, over time the moisture, deformation, mold, yellow is sure

Q: Calcium silicate board with asbestos and non-asbestos how to choose: In the real life of the decoration of the procurement staff, some are on the building materials how to understand, especially those construction units, many of the construction of the College of Engineering materials is also a little knowledge, so that caused by the misunderstanding of building materials, On the current calcium silicate board, basically divided into two kinds, one is decorated with, and the other is the ceiling with the

Q: Calcium silicate board can do the shape of the ceiling? If the figure can not, figure in the shape of what is generally used to do?: This can be done, because the technical problems can not do a lot of modeling, and now has been, if you are in Anhui, Anhui can send us to send new materials Co., Ltd. to see, we solve a lot of different modeling problems, perhaps There you need
