$High Quality Refractory Castable For Cement(Low Iron)$

Q: what is best for making refractory insulation for Blast furnace, hot stove.: High dimensional insulating blanket.

Q: How to divide the materials according to the National Fireproofing Material Standard?: according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several classes: Class A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk.

Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?: Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)

Q: Who knows the fire resistant level of the rock wool color plate?: The rock wool color steel rock wool board is used in a area of high ??fire safety requirements. According to "interior decoration of buildings for fire protection design", the color steel rock wool board belongd to level A. Its life is more than 15 years and still can be used when the temperature is up to about 700 ℃, with maximum fireproofing hour of six hours. And the rock wool color plate is a environmentally friendly material, the preferred material in the construction industry .

Q: How to determine the fire resistance rating of the aluminium-plastic?panel?: Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.

Q: What are fireproofing materials?: Class A incombustible material: Granites, marbles, terrazzos, cement products, concrete products, plasterboards, clay products, glass, tiles, mosaics, steel, aluminum, copper alloys; B1 class flame nonflammable materials: Ceiling materials: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool decorative acoustic panels, glass wool decorative acoustic boards, perlite decorative acoustic boards, flame retardant plywoods and medium density fiberboards, rock wool decorative panels, flame retardant woods, aluminum foil composite materials, flame retardant phenolic laminates, aluminum foil glass fiber reinforced plastic composite materials; Wall covering: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool boards, glass wool boards, perlite boards, flame retardant plywoods, flame retardant medium density fiberboards, fireproof plastic decorative plates, nonflammable double-sided particle boards, multicolor paints, nonflammable wallpaper and textile wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wood composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.

Q: What substitutes are available for high-end refractories in addition to zircon sand?: Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..

Q: Who knows about the B-level fireproof insulation materials?: Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.

Q: About the use of horseshoe glass kiln refractories: the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric?smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.

Q: What are the main materials in concrete fireproofing material?: it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
