- 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:What dose the fireproof and thermal insulation material include?
- It includes A1: Non-combustible inorganic monomer; A2 Non-flammable organic compound, namely composite material; A3 Modified phenolic fireproof materials.
- Q:What kind of material is refractory fiber?
- 1 Refractory fiber cloth can be divided into resistant to temperature of 600 degrees and 1000 degrees temperature resistant (short-term resistance to extreme temperature 1260 degrees). The thickness of two kinds of cloth is typically 1mm 1.5mm 2mm 3mm 4mm 5mm with the width of 25mm-- 1200mm. 2 Specially woven fiber is not easy to fall off, does not irritate the skin, has large tensile strength. It is white and inexpensive. After contacting with water, the tensile force will be reduced. The thickness of refractory fiber cloth whose resistance of temperature is 1260 degree is generally 2mm 3mm 5mm, and the width is 25mm - 1200mm. It has high temperature resistance, great tensile force, and it is non-toxic, white, resistant to fire and water. We can offer products with different specifications according to customer requirements. It has high temperature resistance, low heat conductivity coefficient, thermal shock resistance, and low thermal capacity; It has excellent high-temperature insulation performance and long service life; It has anti-melting and resistance to erosion of aluminum, zinc and other nonferrous metals; It has good strength under low temperatures and high temperatures; It is non-toxic, harmless, and environmental-friendly; It has convenient construction and installation; Specifications and models are 1.5mm - 6mm, with a general width of 1m, (nickel-chromium alloy wire reinforced, reinforced stainless steel wire, glass fiber reinforced, ceramic fiber coated fabrics, ceramics fiber slag cloth, sintered ceramic fiber cloth, ceramic fiber fumigation cloth). We can also provide other specifications according to customer requirements.
- Q:What are the materials of white firebricks?
- The commonly-used firebricks include alumina bricks, corundum bricks, chamotte bricks, high alumina bricks, diatomite bricks, zircon bricks, lightweight corundum bricks, zirconia bubble bricks and so on ~~~
- Q:What is the use of refractory?
- It is fire-retardant and insulated.
- Q:Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
- Exports should be fumigated outside of South East asia. Pallet packing is the most common, convenient and inexpensive.
- Q:Who can tell me what is neutral refractory?
- Refractories mainly refer to aluminum oxide, chromium oxide and carbon as the main component of refractory materials, such as corundum brick, high alumina brick, and carbon brick. Its characteristic goes to the resistance to both acidic and basic slag. Basic refractories mainly refer to the refractory materials whose mian components are magnesium oxide and calcium oxide, including magnesia bricks, magnesia-alumina bricks, magnesia chrome bricks, dolomite bricks, etc. Basic refractory is good at resisting basic slag erosion.
- Q:What does the function of SiC for refractories?
- Silicon carbide for machine non-metallic materials with high temperature wear characteristics of silicon nitride bonded silicon carbide ceramic cups and other products in a blast furnace ladle brick aluminum silicon carbide as an antioxidant added MgO-C
- Q:How long is the duration of fire resistance of hollow glass magnesium board
- It belongs to second level refractory building. The fire resistance limit of prestressed hollow slab is 0.7 hours, according to provision 3.2.7 and 5.1.5 of fire safety rules. When reaching 20 thick protective layer, the fire resistance limit of the prestressed hollow slab is 0.7 hours. When reaching 30 thick protective layer, the limit of the fire resistance of prestressed hollow plate is 0.85 hours. Protection layer of prestressed hollow board prefabrication is 15, plaster ceiling has 12 protection layers, the total protection layer amounts 27, which can achieve fire resistance limit of not less than 0.75 hour.
- Q:Can quantitative feeder be used in refractory plant? Thank you
- Yes, but the material must be no longer using a simple Q235 material
