Q:What are the high temperature resistant insulation materials at 400?
Thermal insulation materials for thermal equipment and pipes are mostly inorganic insulation materials. This kind of material has the characteristics of no decay, no burning, high temperature resistance and so on. For example: asbestos, diatomite, perlite, glass fiber, foam glass concrete, calcium silicate and so on.
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 are the new energy-saving building materials? What's new?
Mainly include new wall materials, insulation materials, waterproof sealing materials, ceramic materials, new chemical materials, decoration materials and various industrial waste residue comprehensive utilization.
Q:What's the difference between white cement and ordinary cement?
The main chemical composition of Portland cement clinker is calcium oxide, silica, alumina and iron oxide. Calcium oxide mainly derived from calcareous raw materials, such as limestone, chalk, marl; alumina and silica from aluminum silicate containing substances, such as clay, blast furnace slag and fly ash; iron oxide is used in sulfuric acid production of sulfur iron slag. For the content of calcium oxide production of Portland cement lime materials in 52%; silicon oxide content of clay in raw materials up to about 57%, the alumina content is less than 20%. In order to reduce the calcination temperature and to produce part of the melt during calcination, a small amount of iron oxide is often added. Of raw materials but also control the content of alkali and Magnesium Oxide, Magnesium Oxide is content in the cement clinker should be less than 5%, total alkalinity (Na2O+K2O) for general cement should be less than 1.2% of low alkali cement should be less than 0.6%.
Q:Asbestos free calcium silicate board there is a crack in the kettle, what is the reason?
Calcium silicate slab blank (blank off off phenomenon is not forming tube adhesion fingerboard blank above)There are two reasons: one is the blank off the vacuum negative pressure is too large, the blank water is too low, low viscosity; two is felt blocked, the billet made worse.The solution is to reduce the negative pressure, strengthen the cloth washing.
Q:What are the raw materials of cement products? What's the function?
Sand。 Gravel occupies a very large volume in concrete production, reaching 70%~80%. The aggregate surface, structure, adsorption and water content of aggregate should be required. The appropriate amount of sand and gravel can save cement, reduce the cost of concrete production, and improve the strength of concrete.
Q:What's the use of low carbon steel insulated nail hooks for power plants?
Mild steel is a type of carbon steel, and its carbon content is between 0.1% and 0.3%. The so-called carbon steel is also called carbon steel, refers to the carbon content of less than 2.11% of the iron carbon alloy. As we all know, the carbon content of the impact on the iron and carbon alloy is very large, the higher the content, the greater the hardness, but the smaller the toughness, and therefore easy to damage. Low carbon steel, because of its low carbon content, therefore, good toughness, low hardness, easy to carry out a variety of processing, such as welding, forging, etc.. And after some heat treatment, low carbon steel can obtain various properties, such as wear resistance, corrosion resistance and so on.
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 are the main use of lime?
A rigid inorganic cementitious material consisting mainly of calcium oxide. Lime is made from limestone, dolomite, chalk and shell with high content of calcium carbonate and calcined at 900~1100 DEG C. Lime is one of the earliest cementitious materials used in human life. Lime is widely used in civil engineering and can be used in medicine in our country.
Q:Calcium silicate board white ICI belongs to wood surface paint?
No, it isn't。Calcium silicate board material properties should be comparable with cement products, usually referred to as cement board is actually calcium silicate board.
