Q: How long is the duration of fire resistance of autoclaved flyash-lime bricks?: How long is the duration of fire resistance of autoclaved flyash-lime bricks?

Q: How many kinds of fireproof materials are there in the market?: Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam materials is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: rock(ore) wool, foam glass and inorganic thermal insulation mortar. Insulation materials with B1 combustibility mainly are: Phenolics, polystyrene granules, etc. The insulation materials of fire barrier zone can use such A-level materials as rock (ore) wool, foam glass, and inorganic thermal insulation mortar, etc.

Q: What kind of material is good for cabinet fireproof board: What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?

Q: Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?: When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint. Galvanized surface generally is not necessarily needed for brushing fireproof coating. Fireproof and galvanized surface have relatively poor bond strength, so it is advisable to brush transitional lacquer or micaceous iron on the galvanized surface.

Q: About the market issues of thermal insulation material and refractory material.: After all, most people have the characteristics of being accustomed with something and it will not change easily ; second, the South has few material manufacturer, but in the Northeast, there are thermal insulating and refractory material manufacturers, which is in shortage, however, but irt is in the minority, and in many areas it is not suitable for exploitation of mineral (due to heavy industry and agriculture land and other reasons). I hope that my answer will help you. first, in the Northeast, the refractory material is not very rich, but the thermal insulating and refractory material demand is very large; third; fourth, which material is used more relived, after all, we should take the transportation costs into account, and it will depend on the kilns construction engineers being willing to use which kind of material, and the thermal insulation material procurement in northeastern region is mostly from the north.

Q: What type of firebrick does TZ-3 represent?: Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.

Q: What are the models of bauxite with high alumina?: China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.

Q: The development prospect of fire-resistant material: Exported bulk material amounts to exported raw material/ To protect domestic resources, many countries have set linitations on the magnesium content in shapeless refractory material and lisences.

Q: Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?: (1) the height of buildings is greater than or equal to 24 m, the combustion performance of thermal insulation material should be A-level. (2) the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be A- or B1-level. When using B1-level thermal insulation materials, fire barrier zone should be set in each floor. (3) incombustible materials should be used as the protective layer of thermal insulation materials. Thermal insulation materials should be completely covered by protective coatings. The thickness of protective layer should be no less than 3 mm. (4) The base walls should be set in buildings with nontransparent curtain wall structures of metal, stone,etc. The fire endurance of which should comply with relevant provisions of current fire?safety?rules on fire endurance of external wall. The fire endurance and fire protection construction of pier?between?two?windows, window sill walls, skirt walls of glass?curtain?walls should comply with relevant provisions of current fire?safety?rules on building curtain walls. (5) the internal cavity of base walls, as well as the space between the skirt wall and base walls, pier?between?two?windows, window sill walls should be sealed with fire-proof sealing materials at each floor.
