Q: What's the fire?retardant material of roller shutter fire resistance door ?: I am happy to answer this question. Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside. fire resistant rolling shutter doors are divided into special inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. The former has better fireproof?performance, but the later has certain wind load resistance and can be installed outdoors.

Q: How long is the fire resistant limit for ultra thin fire retardant coating?: According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level 2, the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is less than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd.

Q: How long is the duration of fire resistance of hollow glass magnesium board: Hollow glass magnesium board features fire prevention, waterproof, tasteless, non-toxic, not frozen, not rot, not crack, unchanged, non burning, high strength and light weight, convenient construction, long service life and so on, and it has more characteristics among products of the same kind nationwide. Its fire resistance limit is 0.65℃.

Q: How much is the duration of fire resistance of the porous brick shale?: It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃.

Q: Where is refractory used? Thank you!: According to its refractoriness, it can be divided into ordinary refractory (1,580℃ to 1,770℃), high class refractory (1,770℃ to 2,000) and super refractory (above 2,000℃); according to chemical property, it can be divided into acid , neutral and alkali refractories, and including refractory used for special occasion. The current definition of refractory do not only depend on whether the refractoriness is above 1,580℃. At present, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, petrifaction, cement, ceramics, power, etc. Refractory generally has good thermal shock resistance, chemical attack resistance, low thermal conductivity and coefficient of expansion, widely used in chemical, construction material, mechanical manufacturing, and ceramics, accounting for 50% to 60% in the total output. It can resist high-temperature action. Refractory has many varieties. Refractory materials are widely used in metallurgy; chemical properties divided by acidic refractories. In addition, cement, silicates. Refractoriness refers to that when cones sample made from refractory has no load. Currently, refractory refers to that is widely used in metallurgy, including neutral refractory and basic refractory.

Q: What's the B grade fireproofing material?: B1 grade ceiling material: gypsum board, fobrous plasterboard, cement particle board, mineral wool decorative acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, flame retardant medium density fiberboard, rock wool decorative sheet, flame retardant wood, aluminum foil composites, flame retardant phenolic laminate, aluminum foil glass fiber reinforced plastic composite material, etc.; B1 grade wall material: gypsum board, fibrous plasterboard, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood and medium density fiberboard, fireproof plastic decorative sheet, nonflammable double-sided particle board, multicolor coating, flame retardant wallpaper and 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 wooden composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.

Q: What kind of material is refractory bauxite?: Bauxite in refractory industry usually refers to the calcined bauxite ore which contains Al2O3 no less than 48%, while the content of Fe2O3 is rather low. Clinker of bauxite with high alumina is calcined bauxite. Tghe clinker is grey, light yellow and dark gray.

Q: how to classify Insulating Refractory ?: Insulating Refractory by the physical form of the material is divided into: thermal insulation refractory slab, thermal insulation refractory blanket, thermal insulation refractory loose wool, and thermal insulation refractory irregular part. thermal insulation refractory material can also be classified by materials, temperature, manufacturing technique and application area.

Q: what is the material of fixed first rate fire resistant window?: Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
