Product Description
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

calcined alumina bauxite price with Good Quality

Q:What are the common refractory insulation cotton material?: High aluminum, clay brick, aluminum silicate fiber module and so on, inorganic types are glass wool, rock wool, foam glass etc.. Organic: the best one is phenolic foam, compround phenolic foam cement layer is a-level. Aerated concrete and other refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and compround thermal insulation material, expanded perlite, foam clay It is applicable for buildings that have high requirement for fire proof level, foamed concrete, volcanic ash glass.

Q:what is the original materials of fireproof coating?: Main raw material includes high-temperature aluminum surface, expanded vermiculite,closed cell perlite, high mark number cement, Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. For example, indoor thick fire retardant coating for steel structure.

Q:What materials are needed to make the amorphous refractory bricks?: Amorphous refractory bricks have good quality, good reputation, complete in specifications,high refractoriness, strong resistance to slag, and long service life. It’s worthwhile.

Q:Is there vermiculite in refractory?: In refractory field, vermiculite is usually used as fireproof thermal insulation material.

Q:Is there requirement for radiation indicator in refractory?: All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.

Q:Who know about the knowledge of acid refractory material? Please explain in detail.: Refers to the silicon dioxide

Q:How to classify fire resistance rating of brick-concrete structure?: In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.

Q:What's the classification of refractory material?: Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome

Q:what is the specs of thermal insulation refractory slab ?: thermal insulation refractory slab features wear proof, heat resistance, impact resistance, acid or alkali resistance, smoke resiatnce, fire proofing,fungi proofing, mould proof,anti-static. fireproof panel is generally used for countertops, tabletops, walls, cabinets, office furniture, wall hung cupboard. Common Specifications: 2135mm × 915mm, 2440mm × 915mm, 2440mm × 1220mm, thickness 0.6-1.2mm.
