Cement fiber board calcium silicate board
How to distinguish between fiber cement pressure plate and calcium silicate board
1, the 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 other plates made dark, but not natural cement color.
3, asked whether the thin plate and thick plate, if not or can not do, it shows that he is the distribution of calcium silicate board or ordinary fiber cement without pressure plate.
4, if you go to the factory, you can visit the workshop, if steam pressure Fu (commonly known as bullet) is certainly calcium silicate board manufacturers, if there is no press, it is an ordinary cement mill.
Fiber cement pressure plate and calcium silicate board difference
???????Fiber cement pressure plate is cement, fiber and other raw materials after the copy of the pulping from the press after thousands of tons pressed. Calcium silicate board is made of siliceous and calcareous fiber material pulping, in a high temperature environment to produce a chemical reaction generated. So the difference between the two very large, mainly in the following areas:
1, from the raw materials, calcium silicate board and fiber cement pressure plate is the main difference between the calcium carbonate plate cement content, 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 with press, calcium silicate board without press; calcium silicate board has steam pressure Fu, fiber cement pressure plate no.
4, fiber cement pressure plate density than calcium silicate board, fiber cement pressure plate density of 1.5g / cm3 above, calcium carbonate plate density of 1.2g / cm3 or so.
5, the thickness of fiber cement pressure plate can be done 2.5-100mm, calcium silicate board can not do the following 4mm ultra-thin plate and more than 30mm thick plate, the general calcium silicate board manufacturers can only do 6-12mm thickness.
6, the normal production of fiber cement pressure plate color for the cement character, calcium silicate board color is white.
Fiber cement pressure plate and calcium silicate board in common
1, both of the raw material composition is similar, all contain silicon powder, calcium and fiber.
2, both through the process of pulping and copying.
3, both the appearance of the shape and length and width specifications are basically the same.
4, both in the use of many overlapping areas, such as inside and outside the wall and so on.
Fiber cement pressure plate and calcium silicate board are common architectural decoration materials on the market, its appearance and composition are many similar or even the same place, many people can not distinguish, and some businesses even calcium carbonate board posing as fiber cement pressure plate sales , Has reached the purpose of profit. In fact, the two are completely different products, in the national industry standard number also belong to different product categories: fiber cement pressure plate number is JC / T412, calcium carbonate board number is JC / T564.
