Q:What is the main constituent of refractory brick?: Primarily magnesium oxide and sodium silicate as binder.

Q:What are the requirements for the performance of refractory materials?: Refractory materials should have very high refractoriness, high temperature heat load and resistance to softening, melting; with high volume stability, resistance to high temperature and heat load, volume shrinkage and only uniform expansion; high strength at room temperature and high temperature strength, high load softening temperature, under the joint action of heat load and heavy load, no loss of strength, creep collapse; Electric furnace analysis should have good resistance to thermal shock, resistance to rapid temperature changes, no crack, not flaking; with excellent slag resistance.

Q:What 's the highest temperature can magnesium plate glass resist ?: 2 hours, according to the fire resistance test report, 2h

Q:How to apply the alumina powder on refractories?: What kind of the refractories can make the aluminium oxide increase the aluminum content and specific gravity, and erosion-resistant.

Q:Which brand of thermal insulating refractory is good?: The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Refractories are non-metallic materials with good resistance against thermal shock and chemical erosion, low heat conductivity coefficient and expansion coefficient. It requires high temperature resistance in nature. It is difficult to transport suc materials in silicious thermal insulation board production base. Silicious thermal insulation board is a kind of thermal insulation material during casting process. Raw materials are non-porous refractory?aggregate, porous refractory?aggregate, organic fiber and inorganic fiber.

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:how long is the fire endurance of plasterboard?: Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.

Q:I wanna ask about the building insulation materials fire rating?: the classfication of building insulation materials fire rating: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q:How to make the service life of refractory materials longer?: Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
