- Q: What advantage and disadvantages it has compared to common fire insulation materials
- Generally speaking, high fire resistance, non combustible Various standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. I hope my answer can slove your problem
- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- Fire doors and windows are divided into grade A, B and C according to the real national situation, also the minimum fire endurance has been stipulated, namely, the minimum fire endurance of grade A is 1.50 h, that of grade B and C are 1.00 h and 0.50 h respectively. There are wooden fire doors and steel fire doors. The main purpose of it is to reach the time that fire resistance should last. But door?closers are required to install. The fire endurance of A grade wooden fire doors should be no less than 90 min, and that of B grade fire doors should be no less than 60 min, that of C grade fire doors should be no less than 30 min! ! !

- Q: How long is the fire endurance of Grade A fire resisting shutter
- The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire?compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of ?closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
- Q: The classification of fire-resistant material
- Refractory material cna be divided into common and special fire proofing material. Common fire proofing material can be sub-divided in to acid fire proofing material, neutral fire proofing material. and alkaline fire proofing material according to chemical properties. Special fire proofing material can be divided into high temperature oxide refractory, refractory compounds and high temperature composite materials according to the composition. In addition, it also can be divided into common refractory products (1580 ~ 1770 ℃), high-grade refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃) according to the strength . According to the shape, it can be divided into block (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and irregular shape (refractory clay, refractory castable, ramming material and so on). According to sintering process, it can be divided into sintered product, fused cast product and melting jetting product.
- Q: The difference between refractory and thermal insulation material
- Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
- Q: How should refractory cement be used?
- Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.
- Q: What's the classification of refractory material?
- Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
- Q: Refractories for iron-making blast furnace?
- This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.
- Q: what are the types of piping insulation material fire?rating?
- according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several grades grade 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. 2, external wall thermal insulation materials, in accordance with fire rating, can be divided into1) grade A combustion performance thermal insulation material: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
