Product Introduction

Refractory Material Bauxite Clinker for All Kinds of Particle Size

Bauxite, also known as alumina, the main component is alumina, which is hydrated alumina containing impurities, a kind of earthy mineral. White or gray, because containing iron it will brown yellow or light red. Density is 3.45g / cm3, hardness is 1-3, opaque, brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. Mainly used for aluminum smelting, manufacture refractories.

Product Application

Refractory Material Bauxite

1. aluminum industry. For defense, aerospace, automotive, electrical, chemical, and other daily necessities.

2. casting. Bauxite is processed into a fine powder made after the mold casting. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sectors.

3.  used for refractory products. High bauxite refractoriness up to 1780 ℃, chemical stability, good physical properties.

4. aluminosilicate refractory fibers. Light weight, high temperature, good thermal stability, low thermal conductivity, heat capacity of small and resistance to mechanical vibration and so on. For iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, nuclear, defense and other industries. It is the high alumina clinker into the melting temperature of about 2000 ~ 2200 ℃ high temperature electric arc furnace, high temperature melting, high pressure high velocity air or steam injection, cooling, it becomes white "cotton" - aluminum silicate refractory fibers. It can be pressed into fiber blanket, plates, or woven into fabric instead of smelting, chemical, glass and other industrial high-temperature furnace lining of refractory bricks. Firefighters available refractory fiber cloth to make clothes.

5.  with magnesia and bauxite as raw material, adding an appropriate binder for casting ladle whole bucket liner very good results.

6.  manufacture of cement, abrasive materials, ceramic industry as well as various compounds chemical industry can be made of aluminum bauxite.

Q:What are included in roof thermal insulation fireproofing material?
Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
Q:What brands are the best in the A-level refractory materials?
1 International (It is a well-known brand in the field of global boats and protective coatings, the products are famous for its safety, strength and smoothness, Akzo Nobel (China) Investment Co., Ltd.) 2 LANLING (It is a high-tech enterprise, and a large provider of industrial coatings, started in 1980, as well as a famous brand of Jiangsu Province, Jiangsu Lanling Chemical Group Co., Ltd.) 3 Champion (It is a high-tech enterprise who is involved in developing a number of industry standards, it is a industry-leading brand brand of Jiangsu Province Jiangsu champion coating Technology Group Limited)
Q:What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is shorter than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be used. Steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board. As is known to all, steel structure usually will lose bearing capacity usually in 450 to 650 degree, leading to deformation, steel column and beam bending, and be no longer usable at last. Generally fire resistant limit of unprotected steel stucture is about 15 minutes. 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. Steel structure an use surrounding concrete (or masonry), fire retardant coating, fire retardant plate and compround structure to achieve the required refractory limit. Hope my answer will help you.
Q:How about the prospect of refractory material?
Cost reduction Refractory material is affiliated to base material factories such as steel, cement and glass. But the situation becoms more severe due to lmaterial reduction and waste. It is necessary to find a substitutional raw material.
Q:What are the additives and recipes of refractory?
SM water reducing agent
Q:What is the the best matching ratio of refractory cement?
The ratio of cement and sand is about 30 per cent. Properties and Applications of refractory mortar: 1, Good plasticity and easy construction; 2, High bonding strength and strong corrosion resistance; 3, Relatively high refractoriness up to 1650 ℃ ± 50 ℃; 4, Good slag corrosion resistance; 5, Good thermal peeling. Refractory mortar is mainly used in coke ovens, glass furnaces, hot blast furnace and other industrial furnaces. Applied industry: Metallurgy, building materials, machinery, petrochemicals, glass, boiler, electric power, steel, cement, etc. And refractory cement is also known as aluminate cement. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement. Aluminate cement is often yellow or brown or gray. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc. It is a special cement.
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:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
it has fire resistant level, incombustible material,and it should reach grade one level.
Q:Who knows the fire rating of fire partition with steel stud?
1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
Q:What is high alumina refractory?
High alumina refractory: High alumina refractory products, with high refractoriness, compressive strength and refractoriness under load, it is used for masonry of a variety of large-scale blast furnaces such as steel furnace, air heating furnace and electric furnace, and for high-temperature parts of thermal equipment like rotary kilns.
