Q:Who knows how many poured refactory material are there?: Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.

Q:The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide: It's D,1. artificial corundum is mainly composed of three aluminium oxide two4, color glasses are not added cuprous oxide, silver halide is added

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 fire-resistant insulation coating have?: Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature.

Q:Who knows the highest temperature the high-temperature refractory coating can resist?: When coating the fire-resistant coating on a steel beam of a building, paint film thickness reaching 2mm, and steel beams in the building are on fire, the fire-resistant coating can withstand for two hours. Fire-resistant coating is passive fire protection materials painted on the surface of the protected objects (eg. steel structure) , which can be divided into types of thick, thin, ultra-thin and facing according to the thickness. It can be divided into water-based and solvent-based products by medium. Whatever the structure of the building is, it will collapse if it is on fire for a long time. Fire-resistant coating function as isolation layer on the surfaces of the protected objects, delaying the building collapse time to win over valuable time for rescue and fire fighting. I hope this answer can help you.

Q:Preparation of refractory clay: Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.

Q:Where is refractory used? Thank you!: Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.

Q:What are first rate fire resistant window materials?: Natural environmental protection, non-poisoned, non-peculiar smell, non-radioactive; non-combustible, fireproofing, moisture-proof, corrosion-resistant; easy construction, lightweight, high strength, www. jsxsmy.

Q:Who knows the new fireproof and thermal inuslation matertial?: New fire insulation material, having a foam material body, with the following characters: Outside of the foam material body bonds the aluminium foil composite glass fiber cloth, which is bonded by the aluminium foil and glass fiber cloth through fireproof glue. The utility model has the following advantages: Bonding the aluminum foil composite glass fiber cloth to the outer surface of the foam insulation material, will strengthen thermal insulation index, also will prevent the burning of the foamed material, thus ensuring the fireproofing safety of the foam insulation material.

Q:What's the fireproof specification for constrcution external wall thermal insulation materials?: incombustible material: Class A1 (homogenous): such as YT inorganic active insulation material for wall thermal, foam glass, rock(ORE) wool, glass wool, insulation?board of aerogel,expanded perlite series, expaned glazed hollow bead, foam insulation boards, ETC. Class A2 (non-homogeneous composite): such as phenolic foam, gelatine powder polyphenyl granule thermal insulation material, inorganic coating materials and other nonflammable material. phenolic foam insulation board, urea resin foam and board, high flame-retardant polyurethane rigid foam and board, high flame retardant polystyrene cystosepiment, gelatine powder polyphenyl granule heat insulating slurry and other combustible?materials. Requirements for combustion levels of common antiflaming EPS, common inflaming retarding XPS, common antiflaming rigid PU foam board: Class A is incombustible?material (product); B1 nonflammable material (product); B2 combustible?material (product); B3 combustible material (product).
