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 difference between white cement and ordinary 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: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's the use of white portland cement?: All the raw meal with the proper components up to 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, called white portland cement (the white cement).When grinding cement, allow limestone not to exceed 5% of the cement weight.Note: cement is allowed to be added to the grinding mill without damaging the cement properties. The amount of cement added shall not exceed 1% of the cement weight. The addition of additional substance must be tested and reported to the Ministry of construction materials for approval.

Q:What are the main use of lime?: Lime milk and mortar, slaked lime or lime paste, with lots of paint. Lime mortar or slaked lime powder can be used to prepare lime mortar or cement lime mixture mortar for masonry or plastering engineering.

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 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.

Q:Cement is not silicate products: There are different kinds of cement: silicate series, aluminate series, sulphoaluminate series, sulfur ferrite system, etc.

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:Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it: The market is generally understood, but in fact, Eterpan belongs to Guangzhou eternit limited production of the 100 year history of eternit brand board, because the cement product is Belgium hetet group invention.
