Product Description:

bauxite for sale/bauxite buyer/sell bauxite ore

 

Discription:

 

Calcined bauxite is one of the principal ore of aluminum.

Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas.

calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C).

this removes moisture thereby increasing the alumina content.

compared to an alumina content of about 57%to 58%in raw bauxite, calcined bauxite has an alumina content of 84%to88%.

the heating is carried out in rotary kilns.

Q:What is the quote of fireproof and soundproof materials used in KTV?
acoustic material, aluminum foil glass wool, sound-deadening material, glass wool, cinema / KTV dedicated glass wool: The classification of glass fiber products: The category of glass wool felts: The level of insulation cotton: A-level brands: New applications: The origin of GB/T13350-2008: The coefficient of thermal conductivity(room temperature): 0.035 bending at low temperature≤: 0.02 elongation at break: ≤80kPa flexure strength: ≤120kpa Compressive strength: ≤150kpa application temperature: 700 Core material: The shape of glass wool: Fibrous shape: Coil Specifications: Complete quote is 23 Yuan per cubic meter. glass wool board, KTV sound insulation core material: The shape of glass wool: The level of rectangular glass wool: A-level non-combustible brands: Kunnai material: The origin of glass fiber: Guangzhou, Shijiazhuang, Wuhan, the quote there is 8.8 Yuan per cubic meter.
Q:What are the models of refractory cables?
NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
Q:What are the use of fire-resistant material and admixture?
I am engaged in admixture and thus familiar. Welcome to exchange!
Q:What is neutral refractory? Can refractory suppliers tell the main components of it?

Q:I wanna ask about the building insulation materials fire rating?
In China, the main external insulation materials are divided into level A, level B1, level B2 and level B3. According to the current "Combustion Performance Classification Method of Building Materials", level A thermal insulation material is incombustible material and inorganic insulation material. However, there are few level A thermal insulation material on the current market, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the organic insulation materials are popular in the market. Level B insulation material can be divided into three levels, level B1 is flame-retardant, level B2 is flammable, and level B3 is flammable. Level B1 nonflammable thermal insulation material is determined by the fire endurance of the material, in addition, different parts of material is divided differently! More common is EPS / XPS insulation boards which have added flame retardant through special treatment. B2 level of combustible insulation materials, common to EPS expanded polystyrene foam insulation board and XPS board, that is, we often say that the general board. The ignition point of this material is very low, and it will release a large amounts of harmful gases in the combustion process. level B3 flammable insulation material is a kind of thermal insulation material which mainly made of polyphenyl foamed. Since this material is highly flammable, it has been eliminated. Civil construction insulation materials, popular building insulation materials in China's current market are mainly made by three organic foam, such as EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane)
Q:Who knows the setting requirements of roofing fire barrier zone?
First, the the minimum of fire barrier width is greater than 30cm, and the thickness should be same to the thickness of the insulation materials. Fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. Fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. Second, Fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. The thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Third, When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. Flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. I hope you can be satisfied
Q:What are the insulation fireproofing materials?
Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.
Q:What's the B grade fireproofing material?
B1 grade ceiling material: gypsum board, fobrous plasterboard, cement particle board, mineral wool decorative acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, flame retardant medium density fiberboard, rock wool decorative sheet, flame retardant wood, aluminum foil composites, flame retardant phenolic laminate, aluminum foil glass fiber reinforced plastic composite material, etc.; B1 grade wall material: gypsum board, fibrous plasterboard, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood and medium density fiberboard, fireproof plastic decorative sheet, nonflammable double-sided particle board, multicolor coating, flame retardant wallpaper and wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wooden composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.
Q:Does anyone know the fire endurance of steel stud partition?
Indeed ① Dragon Brand gypsum board fire-resistant partition: Its fireproofing extreme time is 4 hours, suitable for firewalls of a variety of public buildings, public exit passageway and other partitions, which meets the first level of fire protection standard ② fireproofing and pressure-resistant partition: Refers to the partition which can withstand momentary gas shocks of over 1200pa , mianly used for the room partition with inert gas fire-fighting needs, such as equipment rooms. The pressure-resistant degree of fireproofing and pressure-resistant partition of Beixin Building Materials can be up to 4800Pa, especially suitable for high-rise fireproofing.
Q:Who knows what material is in the center of fireproof rolling curtain?
made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.
