- Q: What is the role of adding chromium oxide green in unshaped refractory materials
- Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
- Q: what's the varieties of fire-proof?sealing?material?
- ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire?bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).
- Q: What are the applications of refractory busway?
- Refractory busway is designed for the power supply in fire-fighting equipment, and it can not be used for other purposes. As the generatrix has good heat resistance, thermal insulation, and the heat of the busway can not be emitted, it can not be used long-term at full capacity. In addition to fire-resistant busway, ther bus lines can operate full-load in long term.
- Q: What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q: Is there vermiculite in refractory?
- Vermiculite is usually used as lightweight material in refractory field, and its volume density is about 0.5.
- Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.
- According to different manufacturing technique, thermal insulation fire-resistant glass can be divided into grouting fireproof glass and composite fireproofing glass. Grouting fireproof glass has good thermal insulation performance, composite fireproofing glass has good fireproof?performance.
- Q: What are the filling refractories in door leaf of class A fire resistant door?
- Most manufacturers use perlite board. The price is appropriate.
- Q: What's the classification of refractory material?
- Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
- Q: What's the frequently used refractory material?
- Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica?brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation?board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory?castables, etc.
- Q: What kind of materials are needed to make refractory bricks?
- The components of the raw materials of refractory bricks. There are many types of raw materials, mainly divided into six categories: Earth, stone, sand, ore, powder and others. No.1, earth: bauxite, kaolin, clay, kieselguhr. No.2 Two: stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite and dolomite, sillimanite and spinel, silica. No.3: sand: ceramic sand, zircon sand, quartz sand, magnesia. No.4, ore: chrome ore. No.5, powder: Metal powder, silicon powder, metal powder. No.6, others: Asphalt and graphite, phenolic resin, perlite, cenosphere, sialon corundum silicon sulfate, silicon carbide, water glass, silica sol, boron carbide, calcium aluminate cement, nitride materials, shale ceramsite, alumina, aluminum sol, zirconia.
