Q: What are the production methods of calcium silicate board material?: At present most of the static process, the raw materials and auxiliary materials according to a certain proportion, adding an appropriate amount of water, while stirring heated to a certain temperature of the gel, and then after molding, autoclave curing, drying is calcium silicate insulation material products. In static method, diatomite is used as siliceous material, calcium material is more lime. The process is simple, low cost, but when the production needs of large capacity and high pressure kettle, the reaction is not complete, the main form of Tobey mullite type calcium silicate board, the use of low temperature (<650 degrees Celsius), it is difficult to produce light and ultra light high strength products.

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: 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: 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: 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: Cement is not silicate products: So, we usually call cement as cementitious material - cement products

Q: What are the new energy-saving building materials? What's new?: 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's the use of white portland cement?: White portland cement as the raw meal with the proper components till 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. When grinding cement, allow limestone not to exceed 5% of the cement weight. White cement is mostly ornamental, and its manufacturing process is much better than ordinary cement. The gap is mainly used to hook white tiles, is generally not used in the wall, the reason is not high strength. It is available in the building materials market or decoration materials shop.

Q: What's the difference between white cement and ordinary 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 exterior walls of the building besides the benzene board and the extruded board?: Composite silicate insulation material has the characteristics of strong plasticity, low thermal conductivity, high temperature resistance, small drying shrinkage and so on. The main types are magnesium silicate, silicon magnesium aluminum and rare earth composite thermal insulation materials. But in recent years as a leader in thermal insulation material of Sepiolite Composite silicate insulation material, because of its good insulation performance and the application effect, has attracted great attention in the construction industry, has shown strong market competitiveness and broad market prospect.
