Calcined bauxite

Bauxite is earthy mineral which consists mainly of Al2O3 , a kind of hydrated alumina containing impurities. According to the usage, It can be divided into the levels of Metallurgy, chemical industry, grinding, cement, and refractory. Clinker is pale yellow and dark grey. It is mainly used for high aluminum refractory material, and also can be used to make the fused corundum. Our materials of calcined bauxite is mainly D-K Style Bauxite Ore.

Q:What are the main materials in concrete fireproofing material?
it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire retardant coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?
As far as I'm concerned, in the construction of high-temperature refractory mortar, these matters should be noted: 1. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
Q:Why the refractories should be waterproof and wetproof
The binding agent of many raw materials is water-soluble. It will be useless when meeting water.
Q:Refractory inquiries
Aluminosilicate refractory refractory material refers to SiO2-Al2O3 as the main ingredient, according to how much the Al2O3 content can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%) three.
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
Graphite, Magnesium Oxide, and alumina are all feasible.
Q:what grades are fire resistance of fireproofing glass divided into?
According to the fire resistance levels, it can be divided into three categories: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properities of transmittance,fireproofing(smoke insulation, fire resistance, and keeping out thermal radiation), sound insulation, shock resistance. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc.
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:The history of refractory material
Q:How to divide the fire rating standards of insulation materials?
1. According to the GB8624-97 national standard, building materials can be divided into following levels in terms of combustion performance. A-level: Non-combustible building materials: Materials almost don't burn. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1. Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powdery particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:What is the difference between wear-resistant material and refractory material?
One is to require wear-resistance. It can be both fire-resistant and wear-resistant, and they can enter different categories. Faced with different demands, it has a variety of features. But both can also be integrated. I think many materials have same division. One is fire-resistant. The two concepts are different division. They are not comparable.
