Disxription:
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. Very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.
Usage:
(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc.
(2) precision casting. Alumina clinker made after the mould precision casting processed into fine powder. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, and good physical properties.
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries.
[5] in magnesia and bauxite clinker as raw materials, add the appropriate binder, used for pouring ladle whole ladle lining has particularly good effects.
[6] manufacture alumina cement, abrasive materials, ceramic industry and chemical industry can be aluminum of various compounds.
- Q: How long is the fire-fighting time of A class fire resisting window?
- Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.
- Q: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
- I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.
- Q: What is the principal part of silicious refractory material
- blast furnace hot blast stove and ceramic tunnel kiln vault, etc., the softening temperature under a fixed load is high (1690-1710 degree), glass melting furnace, lightweight silica bricks and generally the silicon?dioxide is greater than 93% and used above the 600 degree. I had undertaken to complete the 50,000 tons over two advanced silica brick production line design. It is a typical acidic refractory. At present, it is mainly used to coke oven which the masonry operating temperature is higher than 600 degree, with good acid resistance of slag erosion, including silica?brick, good thermal conductivity, high thermal vibration stability, product with fused quartz, close to its refractoriness silicious refractory SiO2 which is as the main component of refractory products.
- Q: Who knows the model of fireproofing materials?
- There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire?rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.
- Q: What's the fire endurance of hollow brick?
- Light weight, high strength, thermal insulation, sound insulation and noise reduction. environmental protection, no pollution, the ideal filling material of frame structure building, Disadvantages:: poor seismic performance, fire reistance being less than 1000 ℃.
- Q: What is the classification standard of fireproofing material levels?
- the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. class B1: combustible?building?materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F
- Q: What are the insulation fireproofing materials?
- Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
- Q: What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
- Well, you have no furnace to cast disposable molds. You can sieve sand which is used for blending cement with siever (left the most fine behind)! And then you can go to hardware (parts) factories directly with molds to ask them to pour. Remember that brass (60 copper) needs to be heated to 1200 ℃, while the crucible is not needed.
- Q: What high-molecular polymers can be used as fire-resistant material binder?
- Organic silicon
- Q: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
- 1.The insulation materials with A-level combustion performance: EPS Hairong module, rock wool, glass wool, foam glass, ceramic foam, foam cement, closed-cell perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. The insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene boards(XPS), Polyurethane(PU), Polyethylene(PE), etc. See the 2009 measures of building technology. The A-level insulation material is only fireproof, the insulation performance of it is worse than that of organic XPS \\\\ EPS material. Currently I think that the best insulation material should be Hairong EPS module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range.
