Bauxite, alumina or bauxite miner , main ingredients are aluminum oxide, hydrate alumina containing impurities,

is an earthy mineral.White or grey, brown yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3, opaque, very brittle.

Very difficult to melt.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution.Mainly used for aluminium, refractory material.

 

Application of 70% Rotary/ Shaft/ Round Kiln Alumina Calcined Bauxite Refractory Raw Material:

1.Aluminium metallurgy.

2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.

3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.

 It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)

4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace.     After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.

5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.

6.Producing bauxite cement.

7.Abrasives.

8.Ceramics industry.

9.Chemistry industry for all kinds of aluminium compound.

Q:Fire rating of decoration materials
You can refer to (code for fire protection design of buildings)
Q:Who knows about the criteria of fireproof and thermal insulation materials?
Seven levels are divided according to "The classification of combustion performance of building materials and products", namely, A1, A2, B, C, D, E, F. It mainly refers to the combustion performance of materials. You can check on this standard for the specific dividing evidence. There are detail charts which mainly describe that whether there is drip or not, the ignition time, continuous burning time and so on.
Q:Which region use more refractory?
Tangshan of Hebei province, Jincheng of Shanxi province, Wuxi of Jiangsu province, Wuhan of Hubei province
Q:Which manufacturers have the best fire-proof materials with light weight?
Recommend Hubei Boyuejia Industrial Co., Ltd. It is a specialized high-tech enterprise that integrates research and development, production, sale and installation of new lightweight fireproof partition panel, partition panel, new partition panel and mechanical equipment. Products are lightweight, fireproof, waterproof, sound insulation, thermal insulation, fracture resistance, anti-permeability, environmental protection, strong constitutive property (dense humidity) and other superior performances. It can be widely used in all types of lightweight wall panel of all kinds of buildings, and is one of the preferred materials of plant, residence, hotel, office building and public buildings.
Q:who knows the technology of fireproofing material?
First: Firstly, you should produce the recipe and prepare the raw materials, for example, if you prepare to produce 1 ton, you should compute the recipe sheet of 1 ton producing; check whether the raw materials are complete; second: make the color and filler thick liquid; add water in order and proper auxiliary in a low speed, then put color and filler (generally we should firstly add something with large oil absorption), wash the meachine after putting the powder. Then seperate them for about 20 miutes in a high speed, until the fineness is qualified; of course, if you need sander, i think you only need sino-soviet differential powder material and non-obvious particles. Third: Paint mixing period: after making the color and filler thick liquid, reduce the roll speed into about 600 roll per minute, add emulsion and proper auxiliary, finally adjust PH and viscosity.

Q:Is the ball mill used in production of refractories?
It will be used. It is used in the process of milling the raw material which is less demanding on technology and in relatively large amount. Is there lots of network marketing for refractory industry? Is the competition fierce on the Internet?
Q:what's the classification of fireproof materials?
Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof panel, fire door, fireproofing glass, fire retardant coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
Q:What is refractory?
Refractory materials are widely used in metallurgy, machinery manufacturing, chemical industry, petroleum, power and other industrial fields. It is an inorganic nonmetallic material mostly used in metallurgical industry with the minimum refractoriness of 1580 ℃, able to resist high temperature without softening (annealing). It accounts for 50% to 60% in total output. Refractoriness refers to refractory's ability to resist fire.
Q:What types does soft fire prevention materials have?
1. In new fire retardant coatings, expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder are an integral part of thick film type fire-retardant coating. They are also the main factors influencing the fire fire retardant coating performance level. And fireproof heat insulation performance of fire retardant coating is based largely on the back fire coating surface temperature factors, and also related to the fire resistance. If the time of reaching the same temperature is longer, it means its insulating fire stays is better, so the fire resistance is higher. 2. The new type of fire prevention board. Now new type of fire prevention board are welcomed by the people is mostly due to its environmentally friendly. And with an increasing number of high-rise building, the fire and strength requirements are constantly improved. It is a big test for plate performance and the standard. Now fire prevention board mainly adopts siliceous materials or calcareous materials, and then stick with the fiber material, light aggregate, binder and the mixture of chemical additives. In this way, it can not only act as fire prevention, but also can improve the thermal insulation performance, and with light quality, good bearing capacity, good durability, no aging problem. More importantly, it is environmental protection. 3. The new flame retardant materials. New flame retardant material currently focus on in polymer composite material, which performance is good with very good high temperature resistance and heat resistance, therefore it's not easy to deform after the fire. At high temperature, it also can use for a long time, so as to ensure the safety.
Q:How to hang the suspended brick in the refractory masonry?
First you can weld the metal fastener of the suspended brick and then hang up the brick.
