Q: How can refractory materials be divided?: Refractory materials in China can be roughly divided into refractory products and unshaped refractories.

Q: Refractory material, refractory brick: 1, according to the degree of refractoriness:Ordinary refractory material: 1580 ~ 1770 DEG CAdvanced refractory material: 1770 ~ 2000 DEG CSuperfine refractory material: >2000 DEG C2, depending on the shape and size of the product:Standard type: 230mm * 113mm * 65mm;No more than 4 measurements, (size ratio) Max:Min<4:1;Profile: no more than 2 concave, (size ratio) Max:Min<6:1;Or an acute angle of 50~70 degrees;Specific type: (size ratio) Max:Min<8:1;Or not more than 4 or a sharp angle; 30 ~ 50 degrees;Special products: crucibles, vessels, tubes, etc.3, according to manufacturing methods, refractory materials can be divided into:Fired products, unfired products, unshaped refractories4. classification according to the chemical properties of materials:Acid refractory material, neutral refractory material, basic refractory material

Q: How long is the duration of fire resistance of hollow glass magnesium board: Hollow glass magnesium board features fire prevention, waterproof, tasteless, non-toxic, not frozen, not rot, not crack, unchanged, non burning, high strength and light weight, convenient construction, long service life and so on, and it has more characteristics among products of the same kind nationwide. Its fire resistance limit is 0.65℃.

Q: Who can tell me about the foundry refractory materials?: The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming?mass, castable refractory, refractory cement, silica sand, magnesite, etc.

Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?: fused cast bricks, fused zirconia corundum blocks, corundum, high zirconium

Q: Which kind of furnace hearth refractory is better?: Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica?bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.

Q: Who knows the external wall thermal insulation materials fire rating requirements?: The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height

Q: What's the type of fire proofing thermal insulation materials?: Hello! Fire proofing thermal insulation material can be classified as inorganic thermal insulation material and composite thermal insulation material. According to the form, it can be divided into fibrous veneer, mineral wool, rock wool, glass wool, aluminum silicate cotton, ceramic fiber, microporous diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete, bubble foam glass, ash, glass, clay, foam concrete, and pasted paste powder polystyrene particles insulation pulp, etc. They are characterized by flame retardancy and fire proofing and thus can be used in buildings with high fire proofing class. Among them, calcium silicate, aluminum silicate and asbestos can also be used for the thermal insulation for heat supply pipelines.

Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?: There are two kinds: 1, the thickness of the plate is between 20 ~ 50 mm with composite structure 2, sheet thickness is between 6 ~ 15 mm calcium silicate fire prevention board.

Q: Could you tell me how does fire protection standard of decorative material is divided?: Level of fire prevention materials: A grade: non-combustibility building material, almost without burning materials. A1 level: non-combustible, no flame A2, non-combustible, to measure smoke, to be qualified. B1 level: flame retardant building materials: flame retardant materials has good flame retardant effect. It is uneasy to burn when encountering open fire in the air or under high temperature and is not easy to quickly spread, and when the fire source move, it will stop burning immediately. B2 level: combustibility building materials: combustibility materials has good flame retardant effect. It will immediately burst into flames when encountering open fire in the air or under high temperature. It easily leads to the spread of fire, such as timber, wooden frame, wooden beams and wooden stairs. B3 level: flammable building materials, without any flame retardant effect, easy to burn, and with a very high fire risk.
