Calcium Silicate Fire Board
These are high quality building materials. The board contains inorganic raw materials.such as cement, silica powder and reinforced cellulose fiber as the main materials.All boards are autoclaved to become stable product. Fiber cement.board does not contain any of asbestos, however, it has strong bending strength like those with asbestos. Fiber cement board can be applied not only for the interior use but also for the outdoor wall system. It has low water absorption rate and high impact resistant ability. These good advantages make it suitable for any purposes of applications.

- Q:What is the main role of fly ash added in concrete products?
- The workability of fresh concrete can be improved by adding fly ashThe workability of fresh concrete is affected by the volume, water cement ratio, gradation, shape and porosity of the aggregate. The fly ash is used for fresh concrete is the obvious benefits of increasing the slurry volume, slurry filled with aggregate between pores, inclusions and lubrication of aggregate particles, so that the concrete mixture has better cohesiveness and plasticity. The aggregate particles of fly ash can reduce the interfacial friction between the paste and aggregate, and improve the workability of the concrete mixture at the contact point of the aggregate.
- Q:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?
- Aluminum silicate fiber can be divided into many kinds according to the aluminum content, the use temperature range is relatively large, the heat insulation property is good, but the price is more expensive.
- Q:What are the three major effects of fly ash in concrete?
- Fly ash "micro aggregate effect" in the fly ash particle size is very small beads and debris in cement can be the equivalent of unhydrated cement grains, tiny beads equivalent to nano material and lively, can significantly improve and enhance the structural strength of concrete and improve the homogeneity of products, and compactness.
- Q:What's the use of white portland cement?
- All the raw meal with the proper components up to the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material, called white portland cement (the white cement).When grinding cement, allow limestone not to exceed 5% of the cement weight.Note: cement is allowed to be added to the grinding mill without damaging the cement properties. The amount of cement added shall not exceed 1% of the cement weight. The addition of additional substance must be tested and reported to the Ministry of construction materials for approval.
- Q:What is the best price for the use of calcium silicate ceiling?
- Water will melt or become yellow, mildew. So if you choose their ceiling, you must first deal with the roof leak. Calcium silicate board with artificial and material prices of about 22 square meters, mainly for office space, and residential corridors and other public places decoration. Integrated ceiling is not afraid of water.
- Q:What kind of insulation material can withstand 350-600 degrees of high temperature?
- Suggest that you refer to the above two data to choose from, select only from the temperature, you can use
- Q: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.
- Q:What are the high temperature resistant insulation materials at 400?
- According to the general rules of equipment and piping insulation, heat insulation material is a material with a thermal conductivity of less than 0.14W/ (m*K) when the average temperature is equal to or less than 623K (350 degrees Celsius). Heat insulation material is usually light, porous, porous, small thermal conductivity characteristics. Generally used to prevent heat loss of equipment and pipes, or frozen (also known as general cold) and low temperature (also known as cryogenic) use, so in our country, insulation materials, also known as insulation or cold preservation materials. At the same time, because of the porous and fibrous structure of thermal insulation material, it has good sound absorption function, so it is also widely used in the construction industry.
- Q:Asbestos free calcium silicate board there is a crack in the kettle, what is the reason?
- Calcium silicate slab crack (crack was autoclaved late cooling stage, it refers to the irregular surface crack, calcium silicate board, or bright or dark is likely to cause fracture, calcium silicate board, low strength, appearance and performance is not up to the requirements)The main reason for the crack is to cool down too quickly.Solution: control the cooling rate, slow exhaust steam.The above is the calcium silicate board equipment in the production of prone to stick, blank, cracks and other phenomena of the reasons and solutions, if you encountered similar problems in production, you can have some reference.
- Q:What heat preservation material is used for thermal insulation of steam pipe in power plant? How thick is the bag? Please advise!
- Superfine glass wool insulation rockwool, steam pipe rubber board, aluminum silicate, calcium silicate products, such as polyurethane insulation form, in the application, to see the price, there are commonly used rock wool and polyurethane, rubber board, the price is relatively low, the thickness of rock wool 65, is the most thin.
