- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- The fire endurance of grade A fire resistance rolling shutter doors should be no less than three hours. Fire doors can be divided into A, B and C grades according to their fire endurance which should be no less than 1.20 h, 0.90 h and 0.60h respectively. Places where are difficult to set fire-proof bulkheads can use fire resisting shutters as partitions of fire?compartments. The fire endurance of fire resisting shutters that include unexposed surface temperature rise as judging condition should be no less than 3 h. Fire resisting shutters that exclude unexposed surface temperature rise as judging condition should set up independent protection of closed automatic water spray system on both sides of shutters, and the duration of water spray system should be no less than 3.0 h.
- Q: What's the refractory material?
- Frequently used refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia. In general, the refractory material include the above. For more information, you can ask for specific advice.
- 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 fire resistance ratings of the glass partition?
- The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The fireproof glass is a special glass which is able to maintain its integrity and insulation in a fire resistance test. According to fire resistance performance, it can be divided into three categories: Class A: The fireproof glass which meets demands of fire integrity and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
- Q: How to divided the grade of external wall thermal insulation materials?
- Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire?rating test
- Q: What is high alumina refractory?
- High alumina refractory: High alumina refractory products, with high refractoriness, compressive strength and refractoriness under load, it is used for masonry of a variety of large-scale blast furnaces such as steel furnace, air heating furnace and electric furnace, and for high-temperature parts of thermal equipment like rotary?kilns.
- Q: Can polystyrene foam color steel plate be used as decorative fireproofing material ?
- As far as I am concerned, polystyrene foam color steel plate cannot be used as decorative fireproofing material. Because polystyrene flame retardant and non-flame retardant of the points, from the fire retardant is generally self-extinguishing. Polystyrene is the polymer synthesized by styrene?monomer through free radicals polycondensation reaction. It is a transparent thermoplastic?plastic. With above 100 ℃ glass transfering temperature,it is often used to make a variety of disposable container and disposable foam lunch box which have to withstand the boiling water temperature.
- Q: On the problem of making refractory materials
- Refractories mainly depend on their high melting point characteristics. The refractory market is mainly Magnesium Oxide material.
- Q: Who knows what fire heat preservation material are there?
- It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: Rock (ore) cotton, foam glass, inorganic thermal insulation mortar, etc.. 1 thermal insulation materials with class A combustion performance Phenol, powder polystyrene particles etc.. Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.
