Q: What are the fire protection standards of insulation materials?: This question is, like this. The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.

Q: What requirements should refractory materials meet?: Ladle is an necessary equipment to undertake molten steel and continuous casting. As many kinds of steel needs to be processed in the ladle, including argon blowing tempering, alloy composition fine-tuning, refining dusting and vacuum processing, working conditions of the ladle lining have worsened. Their working conditions are as follows. (1) The temperature of molten steel is higher than mold casting ladle. (2) the molten steel stays longerin the ladle. (3) ladle lining are subjected to volatilization and agitation of molten steel under high temperatures and in vacuum. (4) The impact on the lining when undertaking steel liner when the impact effect. Therefore requirements of the ladle refractories are as follows: (1) It can resist high temperature. Molten steel should be able to withstand high temperatures without melting. (2) It can resist thermal shock and can withstand molten steel without cracking and spalling. (3) It can resist slag erosion. The ladle should be able to withstand the erosion of lining caused by slag and alkalinity changes of slag. (4) it should have sufficiently high temperature mechanical strength to withstand the agitation and scouring of molten steel. (5) lined should have certain swelling property so that lining will be united as a whole under the effect of hyperthermal molten steel.

Q: What is the fire endurance of ceramsite concrete blocks?: The heat conductivity coefficient of grade 800 hollow building blocks in ceramsite concrete is 0.23 and fire endurance is 4h. Ceramsite concrete has strong construction adaptability. It can not only compound concrete material with different unit weight and strength(It changes with the structure of thermal insulation or bearing structure) according to the different purposes and functions of buildings, but also is easy to construct. It is suitable for industrial production of a variety of construction methods. It can not only make all types of components(board, block, girder, column, etc) by using production process, but also can use mechanization construction of cast-in-place. The strong adaptability of construction of ceramsite concrete is not comparable to any other lightweight building materials(such as air-entrapping, etc.).

Q: In entering fire door, which material does well?: Cold rolled steel, or after a flame retardant willow eucalyptus wood, filled up with perlite inside! Fireproof heat insulation. Price is between 300-900, depending on what technology it uses! Company's large-area substrate door (paint) is cheap door, in commonly 350. Followed is without lacquer, which has a layer of decorative materials, generally between 380-500. Finally there is high-grade, which price is around $900. 0...

Q: Who can tell me about the foundry refractory materials?: Such as: neutral, alkalic, acidic refractories. Of course, the raw materials of different materials are not the same. Such as: the magnesia-carbon bricks, basic refractory materials: magnesite(electric?smelting, high-purity)+ crystalline flake graphite+ phenolic resin+ additive (aluminate or silicon powder or silicon carbide powder or high-temperature pitch) and so on.

Q: What's the fire endurance of hollow brick?: This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980 ℃ is ok in reality. It depends on how thick your wall is because fire endurance of hollow brick is related to wall thickness. 24 wall can generally endure for 3 hours or more.

Q: Who knows about the grade C fireproof door materials?: I am happy to answer your questions. Wood or steel materials are usually used. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively. I hope my answer can help you.

Q: How is refractory material made?: It is made from carbon materials.

Q: Which one is the best refractory material?: o make it simple, you can kindle it, and observe the burning time. If there is a professional need to be accurate, then you can send it to the professional testing company. As far as I know, the Kebiao Company over the victory bridge, Qingdao can offer professional test. I hope my answer can help you, thank you, hope to be adopted.

Q: What is neutral refractory? Can refractory suppliers tell the main components of it?: The material using Al2O3, clay, bauxite and corundum as the main components is neutral material; the material using MgO and CaO as the main components is basic material; the material using SiO2 as th emain component is acidic material.
