As refractoriness

White Fused Alumina is the main starting material to produce high-grade unshaped and shaped refractoriness and is widely used in the field of iron-steel industry,ceramics,petrochemical industry etc. It is the ideal material to produce the unshaped refractoriness such as large ladle castables,medium and high grade BF trough castables,gunning material,pre-cast shapes and is the main material to produce alumina products such as corundum bricks, corundum and mullite-corundum sagger,refined porous plug bricks, monolithic lance composite nozzle, lining material for high temperature industrial furnaces,etc.

As abrasives

White Fused Alumina can be used as consolidation & coating abrasives, wet or dry sprayed grit, suitable for ultra-precise grinding and polishing in the crystal and electronic industry and can be used to produce high-grade refractoriness. It is suitable to machine high stiffness &high tensile strength materials such as chilled steel, alloyed steel, high-speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc.

Q: What's the feature of construction external wall fireproof and thermal inuslation matertial?: Building external wall fireproof thermal insulation material is made by stirring, casting, foam protecting and cutting with industrial by-product gypsum as the main raw material, adding sulphate aluminium cement, fly-ash, polymer additives and other materials. It has excellent properties of respiratory function , air permeability, water impermeability, recycling system data, wind load resistance, shock resistance, thermal insulation, fireproof and sound insulation.

Q: which kind of fire?bulkhead is better?: Fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible?material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic. As for the combustion test of YD-Ba-type inorganic fire?bulkhead, it's best to be deformation under the flame temperature of 1000 ℃, the indicators comply requirements of GA161-1997, combustion performance reaches A level standards of GB8624(non-flammable). J fire bulkhead is mainly applicable to the fireproofing protection and fireproofing isolation of cables with all kinds of voltage?classes laid on scaffold or bridge. It's widely used in cable project fireproofing and fire?retardant in the places with crowded cables, such as various power plants, chemical companys, iron and steel smelting enterprises, mines,etc. It's also the best fireproofing and fire?retardant materials of fireproofing and fire?retardant projects in indoor decoration of public places, such as large shopping malls, hotels, guesthouses, sports hall, closed clothing market, light industrial markets, theaters and so on. Construction method: Fire?bulkhead products can be cut by saw, according to the shape required to be made in the construction site, using steel brackets or expaned anchor bolt to fix it while assembling, steel brackets should be coated with fire-resistant coating for steel structure. You can also use various cable and fireproofing trays made of fire bulkhead, and used in the board gaps.

Q: I know which material is the fire resistance rolling shutter door: Inorganic fiber cloth as curtain side replace steel fire shutter curtain of steel plate, the thickness of the inorganic fiber cloth is much thinner than the steel curtain plate and the density is very small, so the volume of the same area of ??the inorganic fiber is super fire shutter the same area of ??steel fire shutter half, and weighs only one more out of the same area a few steel fire shutter, however, the inorganic fiber super fire shutter fire but has a very good insulation properties. I hope my answers are helpful to you.

Q: what's the classification of fireproof and thermal inuslation matertial?: 1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.

Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?: Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.

Q: what are the requirements of fireproofing material?: answer: 1 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. 2, fireproof?panel is the most common texture in the market. There are two common types: One is the high pressure decorating refractory slab, it's advantages are fireproofing,moisture-proof, wear-resistant, oil resistant, easy to clean, and it has various colors; another one is glass magnesium fireproof board, external layer is decoration materials, and inner layer is mineral magnesium fireproofing material, and it can endure 1500 degrees high temperature but has bad decoration. Installing fireproof suspended?ceiling in outlet channel of construction, stairwell and corridor can ensure safe evacuation of people and protect people from attacking of fire spreading in the disaster. 3, the production process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.

Q: What's the heat conductivity coefficient of fire-resistant material?: 5～5 (Unit: W·m-1·K-1). The symbols are λ or K. Thermal conductivity and material properties Thermal insulation material generally is 0, and is related to organizational structure and working temperature. Thermal conductivity of the material refers to the heat transferred from from one plane to another plane in 1 seconds. Generally the thermal conductivity of fire-resistant material is 1. The larger the value is, the stronger the thermal conduction performance is. If the temperature of two planses differes for 1K, then the thermal conductivity is 03~1. The plane cover 1square meter.

Q: Can anyone say something about what A-level fire-proof decorative material is?: Combustion performance rates of decoration materials ratess combustion performance of decoration materials A incombustible B1 flame retardancy B2 flammability B3 high flammability The B1 rate combustion performance of gypsum plaster board and mineral wool acoustic panel absorber installed on steel joist can be used as A-level decoration materials. Inorganic decorative coating applied on the A level substrate can be used as A level decoration materials. Hope you adopt

Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?: 1, these refer to fire resistance rating of building materials. 2, As for steel, elements that used in different parts should reach different duration of fire resistance according to fire resistance rating. For example, fire resistant pillars of first level can endure fire within 3 hours; the second level, 2.5 hours; the third level, 2 hours. With respect to beams, three levels of fire resistance are included.

Q: what's the detailed address of fireproof and thermal inuslation matertial market?: following are the detailed address of fireproof and thermal inuslation matertial market: Central China Building decoration materials market,Hanxi 1 road No 95, Xinyongan Tangcai decoration material makert, Jianghan district Tangcai road No 53, Baoye decoration material wholesale market, Wuhan Wuchang district Minzhu road No 620.
