Q: Who knows what is the requirement for fireproofing of interior decoration materials ?: In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.

Q: Refractory materials are needed for casting metallurgy.: Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.

Q: how is the high-temperature flame-retardant fibre board?: ------ Different category of high temperature materials including refractory and heat-resistant material, inorganic compounds, high-molecular polymer. refractory usually refers to an inorganic material that can endure temperature above 1580 ℃ . They are for building kiln, combustion chamber and other buildings that require heat resistance materials. It is generally made of quartz sand, clay, magnesia mineral, dolomite.

Q: what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q: What are the chemical composition of refractory cement?: Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.

Q: who knows the fire resistant level of fireproof gypsum board ?: The most commonly used ceiling decoration materials rates B1, including gypsum board, fibrous plaster, cement particle board, mineral wool sound-absorbing panels, glass wool decorative acoustic?panel?absorber, perlite decorating acoustic board, nonflammable plywood, nonflamable medium density fiberboard, mineral wool decorative board, flame retardant wood, aluminum foil composites, flame retardant phenolic plywood, aluminum foil glass fiber reinforced plastic composite materials. The fire gypsum board fire rating can reach A. Of course, many of the suspended ceiling gypsum board of inferior quality rates below B1. plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. plaster board mounted on steel stud can be used as A level decoration materials. in accordance with the national fire safety rules on fire durance of walls and ceilings and other components. we can not simply say whether a piece of gypsum board can meet the requirements.

Q: Detailed description of magnesia dolomite refractory material?: The use of low chromium or chrome free refractories is more and more widely used, developed countries in the development of chrome free refractories to replace the chromium containing material, through research and production practice show that dolomite refractories is the refining of AOD furnace, large cement kiln ideal material.

Q: what textures of furnace refractories are good?: First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
