100 mesh abrasive white fused alumina (WFA) for sand blasting

White Fused Alumina/ WFA

White Fused Alumina, a kind of high-grade refractories, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

As refractoriness

White Fused Alumina is the main starting material to produce high-grade unshaped and shaped refractoriness and is widely used in the field of iron-steel industry,ceramics,petrochemical industry etc. It is the ideal material to produce the unshaped refractoriness such as large ladle castables,medium and high grade BF trough castables,gunning material,pre-cast shapes and is the main material to produce alumina products such as corundum bricks, corundum and mullite-corundum sagger,refined porous plug bricks, monolithic lance composite nozzle, lining material for high temperature industrial furnaces,etc.

As abrasives

White Fused Alumina can be used as consolidation & coating abrasives, wet or dry sprayed grit, suitable for ultra-precise grinding and polishing in the crystal and electronic industry and can be used to produce high-grade refractoriness. It is suitable to machine high stiffness &high tensile strength materials such as chilled steel, alloyed steel, high-speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc.

Q: what is best for making refractory insulation for Blast furnace, hot stove.: clay brick, insulating brick can endure relatively high temperature and last longer than the general fireproof fiber.

Q: How many types of special refractories are there?: Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials

Q: How to do environmental impact assessment for refractory Co., Ltd.: The preparation of a report or statement. During the compilation process, any problems should be actively communicated with the construction side. For example, dust collector selection, environmental protection investment, total emission approval. (especially the total emission, you must let the construction side and communicate with the environmental protection bureau to get the total amount, otherwise you write the EIA does not make any sense.) Generally speaking, the preparation of the report is longer, about forty days; and the preparation of the report table is shorter, about fifteen days.

Q: Fire rating of decoration materials: All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A

Q: How to determine the fire resistance rating of the aluminium-plastic?panel?: The fire resistance rating of the aluminium-plastic?panel is determined by two indicators, namely national compulsory standard of GB8624 "Building Materials Combustion Performance Grading Method ", and GB/T17748 "Aluminium-plastic?Composite Panel National Standard" . Classifications of combustion performance of building materials in our country are as follows: A class: Incombustible building materials; B1 class: Flame-retardant building materials; B2 class: combustible building material; B3 class: flammable building materials. The fire resistance rating of the aluminium-plastic composite panel shuld be no less than B1 class. 1. Detection indexes and requirements of fireproof aluminum-plastic composite panel (B1 class): (1) Conduct the test according to GB/T8625-88, the average leftover length of each test specimen should be more than 150mm, (any test piece should have leftover length), and the maximum average flue gas temperature of each test should be no more than 200 ℃; (2) Conduct the test according to GB/T8626-88, flame hight indicators.

Q: Is aluminium oxide refractory material?: Yes. It has high melting and boiling point, stable chemical?property. All refractory material almost contains aluminium oxide. Refractory materials have a large range and need specific requirements. Refractory material is divided into sizing refractory material, shapeless refractory material, ceramic fiber, refractory bricks and castable refractory. It can be subdivided according to temperature rating. Hope it is helpful to you.

Q: What kinds of fireproof materials does the safe use?: The fireproof materials of the safe, cement foam. It is often said recently that the safes with cement inside are bad. Actually, it is not like this. Chemical means are taken to make the cement inside safes rise like a leaven dough so as to achieve good insulation. The principle is the cement foam. Fireproof safes with such techniques have good performance in terms of fireproofing and anti-theft. The manufacturing processes of this fireproof safe are highly technical, some safes with poor techniques have problems in quality. Here are some data of the foam cement.

Q: Could you tell me how does fire protection standard of decorative material is divided?: Level of fire prevention materials: A grade: non-combustibility building material, almost without burning materials. A1 level: non-combustible, no flame A2, non-combustible, to measure smoke, to be qualified. B1 level: flame retardant building materials: flame retardant materials has good flame retardant effect. It is uneasy to burn when encountering open fire in the air or under high temperature and is not easy to quickly spread, and when the fire source move, it will stop burning immediately. B2 level: combustibility building materials: combustibility materials has good flame retardant effect. It will immediately burst into flames when encountering open fire in the air or under high temperature. It easily leads to the spread of fire, such as timber, wooden frame, wooden beams and wooden stairs. B3 level: flammable building materials, without any flame retardant effect, easy to burn, and with a very high fire risk.

Q: Does the aluminum silicate thermal insulation material fireproof?: Yes, because of its low heat conductivity coefficient, and good thermal insulation, it can be setting fire.

Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?: Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material. If it is glass fireproof door, then the door frame should be equipped with fire-proof materials. I know a exclusive shop in Beijing dealing with fireproof doors, called Naecame.
