Q: hat kind of fire retardant materials are there
fire-retardant materials include phosphorus chlorine, bromine and antimony, aluminum, boron based flame retardant, nanometer magnesium hydroxide, high purity industrial grade magnesium hydroxide flame retardant, high purity industrial grade modified magnesium hydroxide flame retardant, composite flame retardant magnesium hydroxide, aluminum hydroxide flame retardant, modified aluminum hydroxide flame retardant, light magnesium-oxide, unsaturated resin flame retardant, silicone rubber flame retardant, polyamide flame retardant, PE flame retardant, PP Flame Retardant, PVC flame retardant, wood flame retardant, special flame retardant for paper, CPE flame retardant, fabric coating rubber flame retardant, flame retardant carpet adhesive, water based coating flame retardant, oily coating flame retardant, power coating flame retardant, ink flame retardant, and heat stabilizer.
Q: What's the fire?retardant material of roller shutter fire resistance door ?
It is composited by inorganic materials, and main componets are perlite and inorganic adhesive, etc.
Q: What is the principal part of silicious refractory material
lightweight silica bricks, product with fused quartz, the silicon?dioxide content is generally greater than 93%, including silica?brick silicious refractory SiO2 as a main component of refractory products
Q: Which brand of thermal insulating refractory is good?
The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Refractories are non-metallic materials with good resistance against thermal shock and chemical erosion, low heat conductivity coefficient and expansion coefficient. It requires high temperature resistance in nature. It is difficult to transport suc materials in silicious thermal insulation board production base. Silicious thermal insulation board is a kind of thermal insulation material during casting process. Raw materials are non-porous refractory?aggregate, porous refractory?aggregate, organic fiber and inorganic fiber.
Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
Q: How long is the fire endurance of Grade A fire resisting shutter
Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.
Q: What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
Q: Why should graphitic refractory materials be used now that graphite can burn?
In theory, any substance can burn as long as certain temperature is reached. Graphite is turned from diamond under anaerobic condition and at high temperature of 2 000 ~ 3 000 ℃. that is to say, ignition point of graphite (lamellar graphite ) under anaerobic condition will be at least above 3 000 ℃. There are many types of graphite, and their ignition points are also different. Ignition point of pyrolytic graphite is much low. Except for a few cutting-edge areas, fire endurance demand for most areas in daily life (eg. brake pad will add a certain amount of graphite) is under 1000 ℃. Therefore, graphite can be used as refractory material. That is, graphite can both burn and can be used as refractory material, which are not contradictory.
Q: Why the corundum can be used as refractory
Because the main component of corundum is aluminum oxide!
Q: Refractory inquiries
Aluminosilicate refractory refractory material refers to SiO2-Al2O3 as the main ingredient, according to how much the Al2O3 content can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%) three.
