What is the difference between calcium silicate board and cement fiber board?
The common point between fiber cement pressure plate and calcium silicate board1, both of the raw materials are similar in composition, both contain silica fume, calcium and fiber.2. Both are processed by pulping and molding.3, the appearance, shape and length and width of the two specifications are basically the same.4, there are many overlapping areas in the scope of use, such as internal and external walls.
How to distinguish fiber cement, pressure plate and calcium silicate board?1, calculate density: calcium silicate board density is much lower than the fiber cement pressure plate, through the weight of the plate can calculate its approximate density.2, look at the color: Although there are manufacturers in order to pretend to be fiber cement pressure plate and deliberately add carbon black and so on, the board made dark, but not natural cement color.3, ask whether there are super thin plate and super thick plate, if not or can not do, it means that he is selling calcium silicate board or ordinary fiber cement, non pressure plate.4, if you go to the factory, you can visit its workshop, if there is steam pressure (commonly known as bullets), it is certainly calcium silicate board manufacturers, if there is no press, it is a common cement plant.
Fiber cement pressure plate is cement, fiber and other raw materials, after pulping, molding, thousands of tons of press. Calcium silicate board is made of silica and calcium plus fibrous material after pulping and formed by chemical reaction in high temperature environment. Therefore, the difference between the two is very large, mainly in the following aspects:1, from raw materials, calcium silicate board and fiber cement pressure plate difference is mainly calcium silicate board cement content is little, with sand and fly ash instead of cement.2, fiber cement pressure plate is a physical product, calcium silicate board is a chemical product.3, fiber cement pressure plate has press, calcium silicate board has no press; calcium silicate board has autoclaved Fu, fiber cement pressure plate no..4. The density of the fiber cement pressure plate is higher than that of the calcium silicate board, the density of the fiber cement pressure plate is above 1.5g/cm3, and the density of the calcium silicate board is about 1.2g/cm3.5, fiber cement pressure plate thickness can do 2.5-100mm, calcium silicate board can not do less than 4mm of ultra-thin plates and more than 30mm super thick plate, general calcium silicate board manufacturers can only do 6-12mm thickness.6, the normal production of fiber cement pressure plate color is cement color, calcium silicate board color is white.
