Ceramic Fiber Mat Thermal Resistance

Q:What's the requirements of fire-fighting criteria of heat insulating material?: Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.

Q:How can refractory materials be divided?: There are many criteria for the classification of refractories.Just referring to a book about refractory.

Q:What is the quote of fireproof and soundproof materials used in KTV?: acoustic material, aluminum foil glass wool, sound-deadening material, glass wool, cinema / KTV dedicated glass wool: The classification of glass fiber products: The category of glass wool felts: The level of insulation cotton: A-level brands: New applications: The origin of GB/T13350-2008: The coefficient of thermal conductivity(room temperature): 0.035 bending at low temperature≤： 0.02 elongation at break: ≤80kPa flexure strength： ≤120kpa Compressive strength: ≤150kpa application temperature: 700 Core material: The shape of glass wool: Fibrous shape: Coil Specifications: Complete quote is 23 Yuan per cubic meter. glass wool board, KTV sound insulation core material: The shape of glass wool: The level of rectangular glass wool: A-level non-combustible brands: Kunnai material: The origin of glass fiber: Guangzhou, Shijiazhuang, Wuhan, the quote there is 8.8 Yuan per cubic meter.

Q:What is acid refractory material?: Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry. Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment. High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.

Q:What are included in roof thermal insulation fireproofing material?: Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.

Q:What is special refractories?: Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use

Q:What are the specifications of fire resistant bag?: Currently there are four specifications: C10, C40, B40 and B50 suitable for steel ladle of less than 60 tons. I hope it can help you.

Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke

Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?: Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming?agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer?performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.

Q:Can anyone tell me which materials are fire-proof high temperature resistant material?: Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
