Q:What are the materials of class A fire resistant window?
The filling materials of steel, wood frame should be non-combustible materials. Fireproof glass can use qualified products that do not affect the fire window fire resistance performance, whose light transmittance should be no less than 75% that of the commom sheet glass with the same layers. Sealing materials between the frame and fireproof glass should be nonflammable materials. Hardware fittings should be fixed supporting products that pass the test.
Q:I wanna ask about the building insulation materials fire rating?
In China, the main external insulation materials are divided into level A, level B1, level B2 and level B3. According to the current "Combustion Performance Classification Method of Building Materials", level A thermal insulation material is incombustible material and inorganic insulation material. However, there are few level A thermal insulation material on the current market, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the organic insulation materials are popular in the market. Level B insulation material can be divided into three levels, level B1 is flame-retardant, level B2 is flammable, and level B3 is flammable. Level B1 nonflammable thermal insulation material is determined by the fire endurance of the material, in addition, different parts of material is divided differently! More common is EPS / XPS insulation boards which have added flame retardant through special treatment. B2 level of combustible insulation materials, common to EPS expanded polystyrene foam insulation board and XPS board, that is, we often say that the general board. The ignition point of this material is very low, and it will release a large amounts of harmful gases in the combustion process. level B3 flammable insulation material is a kind of thermal insulation material which mainly made of polyphenyl foamed. Since this material is highly flammable, it has been eliminated. Civil construction insulation materials, popular building insulation materials in China's current market are mainly made by three organic foam, such as EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane)
Q:What a blast furnace refractories generally?
refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
Q:how to classify the fireproofing material levels A1 A2 B1?
their classification is shown specifically in Fireproof  Specification of Building Interior Decoration Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
Q:I want to consult the fire resistant level standards of external wall thermal insulation materials.
1, The building with the height larger than or equal to 100m, should have the A-level combustion performance. 2, The thermal insulation material of the building, with a height larger than or equal 60m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each level should set horizonal fire barrier zone. 3, The thermal insulation material of the building, with a height larger than or equal to 24m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each two levels should set horizonal fire barrier zone. 4, The thermal insulation material of the building, with a height less than 24m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each three levels should set horizonal fire barrier zone. I hope my answer will help you. Thank you!
Q:Who knows the setting requirements of roofing fire barrier zone?
curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier between two windows, window sill wall and skirt wall should be sealed by the fire-proof sealing material at each floor. I hope I can help you!
Q:What are the material requirements of class A fire resistant door ?
Grade A fire resistance steel door, namely steel wooden doors or steel-wooden composite door, including reinforced wooden door, is usually used in indoor. In fact, it is the door with steel bar inside and density board or blockboard outside.
Q:What is high alumina refractory?
It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.
Q:What kinds of fireproof and fire retardant materials are there?
fireproof materials are mainly non-combustible A material and flame retardant B1materials. Class A non-combustible material: Granite, marble, terrazzo, cement products, concrete products, plasterboard, lime products, clay, glass, tiles, mosaics, steel, aluminum, copper alloy; B1 grade flame retardant materials: Ceiling materials gypsum board, gypsum fiber boards, cement particle board, mineral wool acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, medium density fiberboard flame, rock wool decorative panels, retardant wood, aluminum composites, flame retardant phenolic plywood, aluminum foil, glass fiber reinforced plastic composite materials; wall materials gypsum board, gypsum fiber boards, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood, retardant MDF, fireproof plastic decorative plates, flame-sided particleboard, colorful paint, flame retardant wallpaper, wall covering flame retardant, flame imitation granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plate, PVC plastic sheeting, high-strength lightweight composite panels, fire-retardant molded wood composite board, color retardant plywood, fiberglass and other flame retardant.
Q:Who knows what material is in the center of fireproof rolling curtain?
In fact, in general, the middle of fire roller shutter is fire prevention materials, filled with asbestos fire protection materials in the fire shutter door of the two layer of iron sheet. I hope my answer can help you
