Fiber cement board and calcium silicate board Fiber cement board and calcium silicate board have been tested for a long time in the market. The fiber cement board and calcium silicate board with excellent performance price ratio have been widely praised by industry users. At present, their use in China is growing rapidly. The national competent department has listed them as key development projects. At present, the market of fiber cement board and calcium silicate board is growing at a rate of 18% every year. I believe that they will become It is the new favorite of new building materials. Fiber cement board is made of cement, fiber and other raw materials after pulping and formed by thousands of tons of press. Calcium silicate board is formed by chemical reaction in high temperature environment after being made of siliceous and calcium plus fiber materials. Therefore, there are great differences between them, mainly in the following aspects: 1. In terms of raw materials, the main difference between calcium silicate board and fiber cement board is that the cement content of calcium silicate board is less, and sand and fly ash are used to replace cement. 2. The normal color of cement board is calcium silicate board. 3. Do you have calcium silicate fiber board. 4. The density of fiber cement board is higher than that of calcium silicate board. The density of fiber cement board is more than 1.5g/cm3, and the density of calcium silicate board is about 1.2g/cm3. 5. The thickness of fiber cement board can be 2.5-100 mm. Calcium silicate board can't be made into ultra-thin plate less than 4 mm and super thick plate more than 30 mm. Generally, calcium silicate board manufacturers can only make 6-12 mm thickness. 6. Fiber cement board is a physical product, calcium silicate board is a chemical product. |
