Q:What's the poured refractory material?
According to the volume density, it can be classified as follows: Heavy (>2.0g /cm3), medium heavy (1.0-2.0g/cm3), light (0.4-1.0g/cm3); classified by binding agent: hydraulic bond, chemical bond, coagulation binder, hydraulic and coagulation binder; classified by material: material of clayey, high alumina, silicious, magnesian, alumina-magnesia, magnesian-chrome, magnesia-zirconia, silicon carbide-based, etc.
Q:Who knows the highest temperature the high-temperature refractory coating can resist?
The temperature resistance degree of high temperature coating is different according to different coating types. The temperature resistance degree is vary from tens to thousands, magnesia brick: Greater than 2000 degrees dolomite brick: Greater than 2000 degrees casting corundum brick: Greater than 1990 degrees. The above data come from the network, for reference only.
Q:Which fireproofing materials factory is the best in Xiangyang?
Xiangyang Shenglaide Door Technology Co., Ltd. Location: Taibai Road, Fancheng District, Xiangfan, Hubei Province Xiangyang Ai'ruite Door Technology Co., Ltd. Location: Scientific and Technical Pioneering Park, Xiangcheng District, Xiangfan, Hubei Province Xiangyang Innovation and Ideal Manufacturing Co., Ltd. Location: Xiangyang Xiangfan state Jianshe Road, Xiangzhou District, Xiangyang, Hubei Province
Q:What is the classification standard of fireproofing material levels?
Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion source. Class B2: Combustible building materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
Q:How long is the fire-resistant time of fireproof wooden door?
fire endurance class A (1.5 hours), class B (1.0 hours), class C (0.5 hours).
Q:I wanna ask about the thermal insulation material fire resistant level?
The inorganic glass wool, rock wool and foam glass. Organic: The best is the phenolic foam, phenolic foam composite cement layer is level A.
Q:Which are roofing fireproofing material?
(1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".
Q:Can anyone say something about what A-level fire-proof decorative material is?
Now A-level market is very confusing. The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, while monomer A-level includes rock wool, ultra-thin insulation panel and the like.. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear. I hope the information above can help you. Hope you adopt
Q:What is the magnesium carbon refractory?
The composition of refractory brick There are many types of raw materials of refractory brick, mainly divided into six categories: Soil, stone, sand, mineral, power and others. The first kind of raw material, soil: Aluminum soil, kaolin, clay, diatomaceous earth The second kind of raw material, Stone: Fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
