Q:What is the maximum temperature at which the glass is cured?
There is no definite melting point. Ordinary glass is a substance which is made up of soda ash, calcium silicate and silicon dioxide, and Shi Yinghe feldspar is the main raw material.
Q:What are the exterior walls of the building besides the benzene board and the extruded board?
Calcium silicate insulation insulation materials in 1980s has been recognized as the massive rigid insulation materials in one of the best, which is characterized by low density, high heat resistance, low thermal conductivity, flexural strength, high compressive strength, low shrinkage. But after entering 1990s, the promotion of the use of a downturn, the main reason is that many manufacturers to adopt in order to solve the problem of non asbestos fiber pulp, pulp fiber and not due to high temperature, thus affecting the thermal insulation material of high temperature resistance and increase the breaking rate, and not the economy.
Q:What's the difference between white carbon and carbon black?
Carbon black is the floorboard of white powder X- ray of amorphous silica and silicate products, mainly refers to the precipitated silica, fumed silica, ultrafine silica gel and gel, including powder synthetic aluminium silicate and calcium silicate. Silica is a porous material, its composition by SiO2 nH2O, where nH2O is there the surface hydroxyl form. Soluble in caustic and hydrofluoric acid, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature resistant, non flammable, tasteless, odorless, has the very good electric insulation.
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:Eterpan and yinte in what is the difference?
Calcium silicate board:Calcium silicate board is mainly inorganic mineral fiber or cellulose fiber and other loose short fiber materials with siliceous and calcareous materials as the main cementing material, pulping, molding, in high temperature and high pressure saturated steam curing acceleration, sheet formation of calcium silicate gel made.Calcium silicate board is a new type of building and industrial plate with excellent properties. Its products are fireproof, moisture-proof, soundproof, moth resistant and durable. It is an ideal decorative board for ceiling and partition. Excellent waterproof performance, just can prevent the home improvement for a long time damp deformation, especially in the bathroom for a long time in a humid environment, the use of calcium silicate board ceiling is the best choice.
Q:What's the use of low carbon steel insulated nail hooks for power plants?
The current power plant thermal insulation is mainly carried out by use of various types of insulation materials, thermal insulation materials commonly used include calcium silicate products, pipes, rock and aluminum silicate fiber products, due to their different properties are applicable to different environments. The equipment with temperature at 300-600 DEG C often adopts aluminium silicate products and calcium silicate products to compound heat preservation. While the temperature is less than 300 degrees, the mineral wool products are usually used for thermal insulation.
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: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.
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 is dew point of thermal insulation material?
The heat insulation lining has the characteristics of low thermal conductivity, small density, high flexibility, fire prevention, waterproof, etc..Light weight, 10 96kg/m3, 20kg/m3 following mat, 24 48kg/m3 as in hard, 48 96kg/m3 as core, which 48kg/m can fand a softening point of the ceiling, 500 degrees C, 300 degrees C insulation, the larger the amount, k=0.9.Calcium silicate insulation product was successfully developed in 70s. It has the characteristics of high compressive strength, small thermal conductivity, convenient construction and repeated use. It has been widely used in power systems.Most of the domestic universal small workshop production, have been imported from the United States after the four production lines, advanced technology, instant rejection speed fiber, dry needle felt, stable quality, high temperature 800 to 1250 DEG C.Features: acidity derivative of more than 2, high temperature resistant, general chemical pipe 1000 degrees C more, must use this material. The temperature is about 2000 C.
