Calcium silicate board is composed of siliceous materials (mainly composition is SiO2, such as quartz powder, fly ash, diatomite, etc.),
calcium material (ingredient is CaO, such as lime, calcium carbide, cement, etc.) mud, enhance fiber, additives according to certain
proportion coordination, the copy or moulding, autoclaved curing processes such as made of a new type of inorganic building materials.
Because of its high strength, light weight, and has a good performance can be processed and incombustible, so widely used in Marine bulkhead,
ceiling, and construction of nonbearing wall, there is a requirement for fire prevention and other places.Silicon plasterboard is building gypsum as
main raw materials made of a material.It is a kind of light weight, high strength, thickness thin, easy processing and sound insulation better
building materials, thermal insulation and fire prevention performance is one of the current focus on development of new light plate.
Plasterboard has been widely used in homes, offices, shops, hotels and industrial buildings and other structures within the partition wall,
wall cladding panels (instead of wall plaster layer), ceiling, sound-absorbing board, ground base plate and all kinds of decorative plate.Plasterboard plasterboard plasterboard of face (divided into general (common),
fiber plasterboard, gypsum decorative explain) it with gypsum as main material, add fiber, bonding agent, modification agent, by mixing pressing and
drying.Have fire prevention, sound insulation, heat insulation, light weight, high strength, low shrinkage rate, etc and good stability, not aging, insect-resistant eat by moth, nail, saw, planer, available methods of construction.Acid calcium thermal insulation board points with calcium silicate board and decorate with calcium silicate board.
- 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?
- The typical feature of white cement is high whiteness, with bright color, generally used for a variety of architectural decoration materials, painting, sculpture, a typical floor, terrazzo, white cement can be used to produce white and colored concrete, is the largest cement production decoration.
- Q:What are the main use of lime?
- Lime stabilized soil mixes lime powder or lime powder with various crushed or formerly loose soil, and is obtained by mixing, compacting and curing. It is called lime stabilized soil. It includes lime soil, lime stabilized gravel soil, lime crushed stone soil and so on. Lime stabilized soil has a certain strength and water resistance. Widely used as a building foundation, ground cushion and road base.
- 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?
- 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.
- Q:Calcium silicate board for house ceiling, 6mm or 8mm?
- Mineral wool board ceiling is different than the calcium silicate board ceiling. Or with the calcium silicate board, mineral wool board first big thickness, increase the keel pressure, easy to cause the ceiling of the cave. Second, it is easy to produce some bug mineral wool board. The fire performance of third mineral wool board no calcium silicate board, mineral wool board fourth dampeasily yellow, moisture absorption is not good.
- 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?
- A slab of calcium silicate board production equipment to the emergence of the phenomenon of billet stick (stick billet refers to the calcium silicate board blank attached to the molding cylinder, in shaping cylinder knife when tearing into the surface depression caused by repeatedly feeding back, yield, effect in this case a two quality, three lead to rising production costs)There are two reasons for the phenomenon of sticking: first, the slurry temperature is low, viscosity is big; two, the material is not dehydrated enough, and the moisture content is high.The solution is: 1, improve the slurry temperature, slurry concentration decreased, but the slurry temperature should not exceed 45 DEG C; 2, in the premise of not causing product layer under the vacuum degree increasing, strengthen dehydration, reduce water blanks.
- 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.
