- 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's the varieties of fire-proof?sealing?material?
- Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof?sealing?material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire?compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.
- Q: I want to know what is the slim in the refractory bricks
- Where are you from, I can introduce to you
- Q: how to divided the external wall thermal insulation materials fire rating
- Level A: Incombustible building material is a material that does not occur any burning. Level A1: Noncombustible means no open fire. Level A2 It is noncombustible, and should measure smoke to be qualified. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: inflammable building material has no any flame resisting effects, and is easy to burn, so the fire risk is high.
- Q: What substitutes are available for high-end refractories in addition to zircon sand?
- The composite sand powder can effectively replace zircon sand, with the same operation process, less operation time and environmental protection
- 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: Is aluminium oxide refractory material?
- Aluminium oxide with 2030?C melting?point is a kind of good refractory material. It can be used as analytical reagent, dehydration and adsorbing?material of organic solvent, catalyst of organic reaction, abraser,polishing agent, raw material of aluminum smelting technology and refractory material. Hope it is helpful to you.
- Q: What are the characteristics of clay refractory materials?
- Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.
- Q: Which region use more refractory?
- Places with steel mill, such as Hebei Province, Anshan City of Liaoning Province, south of Wuhan, Shanghai, all of these places have steel mills where use various types of refractories. In addition, architectural material industry, such as cement plant and glass plant all use refractories, but the variety is single, with a large amount.
- 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
