Product Description:

 Round Kiln Calcined Bauxite 85% 3-5mm of CNBM in China

1.Structure of Calcined Bauxite 85% Content 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. 

 

2.Main Features of the Calcined Bauxite 85% Content

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 there.By 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. 

3.Main usage of the Calcined Bauxite 85% Content

Raw bauxite is typically classified according to its intended commercial application,such as abrasive ,cement ,chemical, metallurgical, and refractory .as raw material for use in high alumina and super duty refractory bricks and shapes ,plastics ,castable refractory, motors, gun mixes, ramming mixes, abrasive grains and other products.

Q:Who knows how many fire heat preservation material are there?
They can be divided into wood fire, steel fire and stainless steel fire. Wooden fireproofing material is light weight, easy for installation and second decoration, as well as all types of civil construction and some industrial buildings. It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: 1 thermal insulation materials with class A combustion performance Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.
Q:What are the features of construction class A fire resistant door ?
1, fireproof and thermal insulation Foam cement board is a Class A non-combustible inorganic heat preservation material which has good fireproof performance can remain integrity after 3 hours baking at 1200℃. It can be used in buildings to improve fireproof performance.
Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
The classification standards of B2-level fireproof and thermal insulation materials: 1. the national standard GB8624-97 classifies construction materials combustion performances into several grades, 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. 2.The exterior wall thermal insulation materials can be classified according to fire rating, insulation materials with B2-level combustion performance are: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:What are fire resistant level standards of class A fire resistant door?
Grade standards: class A fire resistant door is an important part of fire-fighting apparatus, and an important step in the social fireproof work. The quality and use of class A fire resistant door is closely related to the success or failure of the fireproof work.. There are steel and wood for class A fire resistant door materials. Only those whose fire endurance is no less than 1.5h can be called class A fire resistant door. In general, the class A fire resistant door internal material is perlite, and still some are vermiculite fireproof board, foam core board, MCcomposite materials, and other fireproofing materials. The thickness of class A fire resistant door is usually 50mm. In places where there is strict requirements for fireproof performance, class A fire resistant door is often installed.
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:How much is refractory spraying coatings?
Price: 1400.00 yuan refractory spraying coating brand / model: Jinshi fire resistant material| Brand: Jinshi fire resistant materials | Place of production: Henan refractory temperature: 1200 ~ 1400 (℃) | Material: Customization according to your needs Price: 2150.00 yuan refractory spraying coating brand / model: Tagore | thermal conductivity coefficient (at room temperature): 0.035W / (m · k) | refractory temperature: 1580~1770℃(℃)Price: 122.00 yuan refractory spraying coating brand / model: Jinshi | Tensile strength: | Compressive strength: tearing strength: Excellent | Temperature: 1000 ℃ | Form: Fibrous The above prices obtained from the Internet are for reference only, and please pay attention to the purchasing price.
Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
As far as I am concerned, polystyrene foam color steel plate cannot be used as decorative fireproofing material. Because polystyrene flame retardant and non-flame retardant of the points, from the fire retardant is generally self-extinguishing. Polystyrene is the polymer synthesized by styrene monomer through free radicals polycondensation reaction. It is a transparent thermoplastic plastic. With above 100 ℃ glass transfering temperature,it is often used to make a variety of disposable container and disposable foam lunch box which have to withstand the boiling water temperature.
Q:Who knows the fire endurance of rock wool color plate?
I'm glad to answer your question and offer you some of my experiences, for reference only. rock wool board is artificial inorganic fiber taking basalt as raw material and produced by melting with high temperature, which has characteristics of lightweight, non-combustible, heat absorbing, small thermal conductivity. The initial research is a common type of application in the building mainly used for industrial buildings which should be consistent with provisions in "the application types and basic requirements of building insulation materials". Successfully tested in June, 1981 Rock wool board is a new type material with fuctions of thermal insulation, fire retardant, sound absorption. The fire endurance of general rock wool board is 140-180 degrees, within two hours, better not exceed this safe period, in order to avoid security risks.
Q:Who know about the knowledge of acid refractory material? Please explain in detail.
Refers to the silicon dioxide
Q:What material is used to make furnace pipe of refractory bricks?
Refractory brick is called refractory brick for short. It is a kind of refractory material fired by using refractory clay or other refractory materials. Faint yellow or brownish. It is mainly used in building smelting furnace and has resistance to high temperature 1,580 ℃ -1,770 ℃. Also known as refractory brick. It is refractory material with a certain shape and size. It can be divided into burnt brick, unburned brick, fused brick (fused cast brick), fire-resistant insulation brick according to preparation technics; It can be divided into standard brick, ordinary brick and special-shaped brick, etc according to shape and size. It can be used as high-temperature building material and structural material of building kiln and all kinds of thermal equipment. It can also withstand a variety of physical and chemical changes and mechanical action under high temperatures. For example, fireclay brick, high alumina brick, silica brick, magnesia brick, etc.
