- Q:In entering fire door, which material does well?
- Cold rolled steel, or after a flame retardant willow eucalyptus wood, filled up with perlite inside! Fireproof heat insulation. Price is between 300-900, depending on what technology it uses! Company's large-area substrate door (paint) is cheap door, in commonly 350. Followed is without lacquer, which has a layer of decorative materials, generally between 380-500. Finally there is high-grade, which price is around $900. 0...
- Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
- Which standard? Please be more specific
- Q:How long is the fire endurance of Grade A fire resisting shutter
- Fire door can be divided into Grade A, Grade B and Grade C fire door according to its fire endurance. Their fire endurance is not less than 1.20h, 0.90h and 0.60h respectively. 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. When the fire resisting shutter is used for fire compartment, fire endurance is 3h. When the fire resisting shutter is set at the opening part of firewall, fire endurance is 1.2h.
- Q:Who can tell me what is neutral refractory?
- Neutral refractories refer to the refractory materials which will not react greatly with both acidic and basic slag at high tempreratures. Such as carbon refractories and chromite refractories. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc.
- Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
- Go eastward 200 meters from the south gate of cultural square.
- Q:which is better as household fireproof material ?
- the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.
- Q:What kind of material is good for cabinet fireproof board
- Natural stone marble: Advantage： Rich color, texture is more soft, easy for cutting or molding; shortcomings: Because it is a natural formation, micro cracks will get easily broken. If sewage infiltrates in during production and transportation, it is difficult to clean and it will get cracked. In the daily cleaning, residue will be filled into the cracks when using cloth to clean. then the material will become breed bacteria. In the long process of the formation, natural stone material may cause harm to human health due to the formation of heavy mental which is radioactive.
- Q:What are included in roof thermal insulation fireproofing material?
- Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
- Q:What are the requirements of refractory temperature of refractory brick?
- Refractory temperature of refractory brick is 1650 degree.
- Q:What are included in fireproofing materials?
- There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire retardant material and its products, textile, fire retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof sealing material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of toxic gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.
