     China Calcined Bauxite Ore Metallurgical Grade Bauxite for Cement Industry

 

Bauxite is a kind of earthy minerals, the main constituent is impurity hydrated alumina. It is white or

off-white, but it will appear tawny or light red because of adding iron.

Bauxite is extremely difficult to melt. It is insoluble in water, but soluble in sulfuric acid and sodium hydroxide solution.

Q:Which kind of external wall fire barrier zone material is better?
I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical plate arranged fiber technology to make the compressive strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.
Q:what's the varieties of fire-proof sealing material?
ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).
Q:Does the production of refractory belong to advanced technology?
Refractory is traditional ceramic material. We can only say that national development is relatively backward. If the refractory is counted as new material, then it still has huge development potential.
Q:How is the performance of refractory materials?
It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
Q:What kind of fireproof material is used for steel structure?
Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities. Agglutination material are classified as fireproof coatings for steel structures which is solvent based and Water-based steel structure fire retardant coatings. Fireproof coatings for steel structures which is solvent based are subdivided into fireproof coatings for steel structures which is solvent based with low benzene content and fireproof coatings for steel structures which is solvent based with high benzene content (TVOC≤600g / L, benzene ≤5g / kg). It can be divided by thickness. ultra-thin (CB) fireproof coatings (coating thickness ≤3mm), thin (B) fireproof coatings (3mm & amp; lt; coating thickness ≤7mm) and thick (H) steel structure fire retardant coating (7 mm & amp; lt; coating thickness ≤45㎜).
Q:What is streaming fireproof material?
Streaming fireproof material is castable refractory that can flow and degas without virbration, which is suitable for thin-wall or places that cannot be molded by vibration because of complex shapes. Well, appropriate amount of water is necessary for it. Its characteristic goes that it can be cast into various shapes of construction body without virbration and it will not reduce or not significantly reduce the performance of castable at the same time.
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:Current development status of qualitative refractory materials.
Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
Q:What are the characteristics of thealuminium oxide refractory?
The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .
