High Alumina Textile Ceramic Rollers

Q: What is the difference between calcium silicate board and cement fiber board?: 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.

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: The ceiling of calcium silicate board and mineral wool board which is good: 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.

Q: What heat preservation material is used for thermal insulation of steam pipe in power plant? How thick is the bag? Please advise!: Steam pipe in power plant thermal insulation rock wool board thickness, according to the temperature in the pipeline to choose, the higher the temperature insulation thickness is generally 80 to 150 mm.

Q: Calcium silicate board white ICI belongs to wood surface paint?: ICI can generally be considered as wall paint (latex paint), and latex paint can be used on this kind of cement board. And lumber is different, it is not suitable to brush latex paint on the surface of wood, it can only be decorated with paint (oil paint).

Q: Eterpan and yinte in what is the difference?: Eterpan:Eterpan, is a kind of fiber reinforced silicate plate (fiber cement board), the main raw material is cement, plant fiber and minerals, the flow of high temperature steam pressure and slurry method, mainly used as building materials.Eterpan is a kind of high strength, durability and other advantages of fiber silicate sheet, with various thickness and density, 100% does not contain asbestos and other harmful substances. For non combustible A1 grade products.The utility model has the advantages of fire prevention, moisture proof, waterproof, sound insulation effect, environmental protection, quick installation, long service life, etc.. Often used for wall panels, bathroom partitions, outdoor roofing, roofing, exterior insulation panels, interior decoration, ceilings, etc.; alsoInstead of gypsum board, used as base material in 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 is the best price for the use of calcium silicate ceiling?: The price of each place and labor costs are not the same, here in Heilongjiang labor costs about 18---20 yuan per square meter, plus keel, hanger, calcium silicate board of about 45----50 yuan per square meter.

Q: What is a building energy-saving materials?: As far as its varieties are concerned, the new wall materials mainly include bricks, blocks and slabs, such as clay hollow bricks, waste clay bricks, non clay bricks, building blocks, aerated concrete, light plates and composite boards.

Q: What are the exterior walls of the building besides the benzene board and the extruded board?: Foam heat insulation material mainly includes two categories, polymer foam type insulation material and foam asbestos insulation material. Polymer foam thermal insulation material has the advantages of small absorption rate, stable heat preservation effect, low thermal conductivity, no dust flying in construction, easy construction, etc., and it is in the period of popularization and application.
