Q:How long is the duration of fire resistance that fireproof window of level B can endure?: Fire proof window of level B is the fire proof window whose duration of fire resistance is not less than 1 hour.　 Technical requirements: One, Materials and fittings (1) the frame of windows draw on steel or wood frames which have certain intensity and are able to ensure the integrity and stability of components. 　(2) Steel frame and layering can use galvanized steel or stainless steel plate. Its selection criteria shall be in line with provisions 5.1 of GB12955< steel fire door general technical conditions >. (4) The internal fillings of steel, wood frames should use non combustible materials. (5) Fire proof windows can opt for qualified products without affecting the performance of fire proof window. Light transmittance of glass shall not be less than 75% of the same layer of ordinary flat glass. 　(6)The sealing material between the frame and the fireproof glass should adopt the nonflammable materials, functioning as the fire blocker. (7)Hardware fittings should be tested for qualified products.

Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?: The main material is quartz sand and it is the cheapest, and can resist 1500℃ without any difficulty.

Q:What's the texture of refractory for the hearth of reverberatory?furnace? ?: The long-term usage temperature of ceramic fiber is between 950-1260 degrees.

Q:Why the corundum can be used as refractory: Do you need white corundum Its main chemical element of corundum is the 99.3% aluminium oxide and it is sintered byelectric furnace, so it can be used as a refractory raw material, the other can also be used as grinding wheel. It is very useful

Q:Which fire-resistant materials have good viscidity?: Viscidity is necessary for gunning mix, repair mix and bordering. It is too broad to which has good viscidity. Both gunning mix and repair mix are powder before adding water. Bordering also has little viscidity before heating. The question shoule be more specific.

Q:Who knows about the B-level fireproof insulation materials?: Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof?performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.

Q:What's the heat conductivity coefficient of fire-resistant material?: The heat conductivity coefficient of fire resistant material is related to bulk density and mainly related to the internal structure. Different materials have different structure and thermal conductivity and temperature . Carbonaceous material can be used for heat dissipation and reach more than 15. For thermal insulation it can be 0.00.

Q:Which manufacturers have the best fire-proof materials with light weight?: Tinajin SPstar Insulation Material Co.,Ltd. is Chinese agent of German Berkson which is engaged in the application of field of high temperature and thermal insulation for many years and has accumulated experience of application of WDS nanometer scale micropore thermal insulation matrial in a variety of industries. Welcome domestic customers and experts in all industries to contact us and cooperate to promote this new energy-saving insulation materials. Make due contributions for China's energy-saving and sustainable development and low carbon emissions project!

Q:What is the acceptance standard of refractory?: It depends on the variety of materials. In general the main test items include chemical composition, refractoriness, refractoriness under load, creep, volume density, linear change, strength, slag resistance, thermal conductivity and thermal expansion. If it is shaped products, it is required to inspect the size deviation and whether it has edge. Detection method accords with the relevant national standards and there are lots of them. You can refer to the standard compilation.

Q:what is the Specifications Grading for Fireproof rubber insulation materials ?: At present, China Building Materials has two grading criteria for combustion performance. "Combustion Performance Classification Method of Building Materials" and "Combustion Performance Classification Method of Building Materials and Products" (GB8624-2006). Among them, one of the major changes of GB8624-2006 and GB8624-1997 is to divide the material combustion performance grading from homogenous material)Class A (composite sandwich material), B1, B2 and B3 level five minutes as A1, A2, B, C, D, E, F seven levels.
