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.
Product use:
1. aluminium industry.Used for defense, aerospace, automotive, electrical, chemical industry, daily necessities, etc.
2 . precision casting. Alumina clinker made after mold precision casting processed into fine powder.Used in military industry, aerospace,
communications, instrumentation, machinery and medical equipment department.
3. for refractory products.High bauxite clinker as high as 1780 ℃ refractoriness, 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.
It is the high alumina clinker in the melting temperature of about 2000 ~ 2200 ℃ high temperature
electric arc furnace, via high pressure of high temperature melting, high-speed air or steam injection, cooling, became a white cotton - silicate aluminum refractory fiber.
It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical industry, glass and other industrial furnace lining brick.
Firefighters available refractory fiber cloth to make clothes.
5. with magnesia and bauxite clinker as raw material, add appropriate binder, used for pouring ladle whole ladle lining has particularly good effects.
6. manufacture alumina cement, abrasive materials, ceramic industry and chemical industry of aluminum compounds
- Q: How long is the duration of fire resistance of hollow glass magnesium board
- Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
- Q: Who knows what kind of material the fire-proof plate use, and is it good?
- It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight?aggregate, adhesive and chemical?additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.
- Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
- Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.
- Q: Does the refractory material used in steelmaking all refer to refractory brick?
- Besides refractory brick, it also refers to unshaped refractories like fire clay and castables.
- Q: What defect does fused cast refractories have ?
- What defect doesfusion-cast refractory material have ? In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are sidewall block and brick kiln bottom. I hope my answer can help you.
- Q: Who knows the roofing fireproofing and waterproof material?
- Many waterproof materials are suitable for civil engineering, and almost used in the roof waterproof layer, such as: Paint categories: 911 two-component polyurethane waterproof coating single component polyurethane waterproof coating polymer cement-based waterproof coating JS composite waterproof coating and so on. . Coil categories: single-sided waterproof roll double-sided self-adhesive waterproof roll modified asphalt waterproof roll (SBS, APP) polypropylene, polyester, polymer waterproof roll, PVC waterproof roll, EPDM waterproof roll
- Q: What's the material of fireproof and wear-resisting floor?
- It is the kind of special concrete floor, and it should prevent from crash for it will produce fire by friction. It is mostly used for the warehouses storing explosive and inflammable objects and chemical materials. And its production process is the same with that of the common concrete floor, but it uses different material which needs to be the pebbles and sand after processing with marbles and dolomite.
- Q: Fire insulation and fireproof insulation board materials What is the difference in performance?
- Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of it. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, Platycodon grandiflorum as the main raw material.
- Q: What is fire retardant coating mainly used for?
- Fire retardant coating is a coating which is applied to the surface of buildings and structures and can form a protective layer of fire retardancy and thermal insulation. It can reduce the flammability of the coated materials and block the rapid spread of fire so as to improve fire endurance of the coated materials. Features of fire retardant coating: (1) Fire retardant coating itself has a flame-retardancy or non-inflammability, and it can prevent the protected substrate from direct contact with the air, and delay ignition and reduce the burning speed of the objects. (2) In addition to flame retardancy or non-inflammability, the fire retardant coating itself has a a low thermal conductivity, which can delay the transfer of flame temperature to the substrate to be protected. (3) When heating, fire retardant coating decomposes non-combustible inert gas to dilute the combustible gas decomposed by the protected, making it difficult to burn or slow down the burning rate. (4) Fire retardant coating containing nitrogen will decomposite NO, NH3 and other basic groups, which compound with the organic radicals and interrupt the chain reaction so as to reduce the temperature. (5) intumescent fire retardant coating will expand and foam when heating, and form a carbon foam insulation to block the protected objects, thus delaying the transmission of heat to the substrate.
