Q: What is the common inorganic fireproof and thermal inuslation matertial?: inorganic materials of insulation materials 1, inorganic thermal insulation materials are mainly concentrated in the materials that have a certain insulation effect and can achieve level A fireproofing, such as aerogel blanket, glass wool, rock wool, expanded perlite and micro-nano thermal baffle. 2, rock wool production is harmful to human body, workers also do not want to occure the situation under the construction. The cycle of rock wool construction plate is long about 2 years from construction to production. The supply of the domestic wool market also cannot meet the requirements for use. 3, expanded perlite has great weight and high water absorption. 4, the insulation performance of micro-nano insulation panels is 3-5 times that of conventional insulation materials, commonly used in high temperature environment, but is more expensive. 5, aerogel blanket is level A1 inorganic fireproofing building materials, thermal conductivity at room temperature is 0.018W / (K · m), and absolutely waterproofing, its insulation performance is 3-8 times of traditional materials, which can replace the unenvironment-friendly froconventional flexible material with poor insulation properties, such as glass fiber products, asbestos insulation felt and silicate products.

Q: What does fire-resistant insulation coating have?: What is the most famous is that grade A is incombustible?thermal?insulation?material. W W inorganic active wall insulation materials, cement foam insulation board, vitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, foam ceramics, etc.

Q: Does hardware construction materials contain refractory?: refractory includes one kind of building materials. It is a special material and not commonly used.

Q: Who knows about the criteria of fireproof and thermal insulation materials?: 1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.

Q: What does the function of SiC for refractories?: As inorganic material, the silicon carbide has the characteristics of high temperature resistance and good anti-wear ability. The sisic products can be used at the blast furnace ceramics. For the unburned?brick, such as alumina-magnesite carbon brick, the silicon carbide can also be added as an antioxidant.

Q: Does anyone know about the A-level fireproof materials?: rock wool external wall composite board, A1-level fire rock wool board, hidden slit rock wool board ? 30, A1-level fireproof mineral wool sound-absorbing board. What about the sound-absorbing sheet? glass fiber acoustic board engineering of the TV backdrop ? 85, A1-level fireproofing and thermal insulation rock wool board is hydrophobic thermal insulation, external wall thermal insulation materials ? 200, high temperature resistant calcium silicate board, LCFC/calcium?silicate?board is A1-level fireproof materials with high-quality and low-price ? 75, the prices above are from the internet for reference only, and the purchase prices vary according to the market.

Q: which is better as household fireproof material ?: the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.

Q: Why the corundum can be used as refractory: It can resiatant to friction wear.The alumina material is a kind of neutral material with high temperature resistance, anti-acid, anti-corrosion, alkali resistance, and high hardness of corundum. The disadvantage is the poor thermal shock resistance, the main chemical composition of corundum is aluminium oxide and the melting point of corundum is 2080 degrees

Q: About the use of horseshoe glass kiln refractories: the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric?smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.
