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:Who know what kind of fire shutter fire rating are there?
There is no national standard for fire protection performance of fire roller shutter in China, and now the executive standard of GB14102-2005 "fire shutter": F1, fire-resistant time 1.50h; F2, fire-resistant time 2.00h; F3, fire-resistant time 3.00h; F4, fire-resistant time was 4.00h before the national standards of fire shutter grading is introduced, expert advice that fire resistance test be made according to national standard, to reach back fire surface temperature rise requirements, if the refractory limit is greater than or equal to 3.0h, it is said to be super fire shutter, if test not inspect unexposed surface temperature rise as a judgement of the conditions, the door is referred to as ordinary fire shutter doors. I hope my answer can help you
Q:what's the materials of fireproof housing?
Prefabricated houses take rock wool board as its wall materials to ensure prefabricated houses and color steel mobile home reach A-class fireproofing standards.
Q:What is glass furnace used high-grade refractory materials?
It is said that building a furnace need 30 million? After the ignition, it can't be gone out. Only at the waste to maintenance?
Q:What's the material of electrical fire prevention board?
Industrial electrical fire prevention board is usually made of flame-retardant fiberboard, and its main purpose is for fire prevention and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface!!!! So the material uses the flame-retardant fiberboard. Hope my answer is helpful for you.
Q:What is the fire resistance thickness of the thin fire-retardant coatings?
There is no detailed requirement on the thickness of the thin steelwork fireproof coatings in the "Code for application technology of steelwork fireproof coating", and the thickness there refers to a certain thickness which must(at least) have fire resistance for a certain time. The thickness of fireproof coatings in engineering generally depends on the manufacturer's test reports. Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
Q:Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
ShiLiDe materials are relatively poor, and have nothing to do with 3M at all. 3M is a brand! 3M company is famous for innovation around the world. It has developed a variety of products in a hundred years, involving in automotive, chemicals, telecommunications, construction and other fields. 3M automotive aftermarket has more than 3,000 products (more than 20% of which are high-tech patented products). The world's first explosionproof and heat insulating film, and the first waterproof abrasive paper were born in 3M Company. The abraser, polishing materials, mirror finish of paintwork, the internal and external auto beauty of 3M Company rank the first place in the world. 3M films are divided into conventional films and crystalline auto films. The conventional films of 3M generally have five-layer structure, the base of films is a polyester film which is s plastic film of tearing and puncture resistance. The film is coated with thermal insulation layer, ultraviolet isolation layer, adhesive layer, wear-resistant layer, and protective layer which finally becomes thermal insulation and explosion-proof film with metal sputtering method. Optical micro-attach technology is used in the polyester film which is the base of 3M crystalline auto film. It is coated with more than 240 layers of optical coatings in order to achieve better thermal insulation performance, and be the top anti-explosion and heat-insulating film with clear sight. I hope my answer can help you. Thank you.
Q:What kind of refractories do the anode baking furnace use?
5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
Q:What are the requirements when producing fireproof materials by kaolin?
Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
Q:how long is the fire endurance of plasterboard?
fireproof endurance can reach a maximum of 4hours, suitable for a variety of public buildings firewall, and partitions for public exit passageway, reaching standard level of fireproof. the lightweight partition made of gypsum board and steel stud is mainly for dividing architecture space. Rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees.
