- Q:I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
- Dalian foreign trade companies are numerous, and fire prevention materials are also quite a lot
- Q:What do refractory materials include?
- What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded?magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
- Q:What kind of refractory materials are used in metallurgy industry?
- Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
- Q:How to choose refractory material
- The crystalline refractory fiber mainly consists of polycrystalline mullite fiber, the optimum use temperature is 1300 DEG C, and the long-term use temperature of polycrystalline alumina fiber is 1400 DEG C. The service temperature of ordinary refractory fiber is 1150 degrees, and the use temperature of advanced refractory fibers (such as alumina, zirconia, refractory fiber) can reach 1700 degrees centigrade
- Q:What kind of fireproof material is used for steel structure?
- Steel is a building material that does not burn, it is shock resistant and anti-bending. In practice, Steel can increase load capacity of the building, but also add asthetic beauty to the architecture design; Unlike concrete, it can bend and stretch. Therefore, the steel construction industry has been favored, such as one-story or multi-story buildings, skyscrapers, factories, warehouses, waiting rooms and waiting hall, which is the common use of steel. However, the steel as building materials has unavoidable defects in fire prevention, its mechanical properties such as yield point, tensile strength and modulus of elasticity, decrease abruptly due to temperature rise.
- Q:what's the classification of fireproof materials?
- Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
- Q:What are fire resistant level standards of class A fire resistant door?
- Grade standards: class A fire resistant door is an important part of fire-fighting apparatus, and an important step in the social fireproof work. The quality and use of class A fire resistant door is closely related to the success or failure of the fireproof work.. There are steel and wood for class A fire resistant door materials. Only those whose fire endurance is no less than 1.5h can be called class A fire resistant door. In general, the class A fire resistant door internal material is perlite, and still some are vermiculite fireproof board, foam core board, MCcomposite materials, and other fireproofing materials. The thickness of class A fire resistant door is usually 50mm. In places where there is strict requirements for fireproof?performance, class A fire resistant door is often installed.
- Q:Which basic refractory is better?
- The following companies are good: 1, Xuzhou Reka Casting Material Co., Ltd. Address: No.22-2 Luoshan Road, Economic and Technological Development Zone, Xuzhou, Jiangsu. 2, Golden Triangle Refractory Plant, Xinmi, Henan. Address: Ganzhou Street, Litang Village, Xinmi City, Henan. 3, Zibo Sun Refractories Co., Ltd. Address: Wujia Village, Shangjia Town, Zichuan(Wenchang Lake) District, Zibo City, Shangdong.
- Q:Does anyone know which materials belong to light fire resistant material?
- Fire partitions can be divided into organic and inorganic fire partitions, the main ingredient of organic fire partitions is organic material, which can be used for cable tray with corrosion-resistant and fire protection requirements, and the main ingredient of inorganic fire partitions is inorganic material, mainly used for fire protection. As the main component is inorganic material, it can not be use in projects with acid-resistant and alkali-resistant requirements. Of course, the price of the same amount of organic fire partitions is generally more expensive than that of the inorganic fire partitions . The fire endurance of these two products of general enterprises are 3 hours.
- Q:Concrete composition and function of magnesia bond used in refractory
- The main component of magnesia binder is silica powder and six partial, the mechanism is gel combination, and six can react with magnesium (basic refractory) to produce complex compound, and improve the strength of products
