72 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.

Advantages

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: Does the external wall thermal insulation materials level b1 need the fire barrier zone?: First, it is prohibited that the thermal insulation material of level B2 and below combustion performance is used in the thermal insulation project of any civil building wall, and the thermal insulation material of below level A combustion performance is used in the thermal insulation project of curtain wall civil builduing that the height is equal and greater than 24m, of non-curtain wall residential building that the height is equal and greater than 100m and of other non-curtain wall civil builduing that the height is is equal and greater than 50m. Civil builduing wall thermal insulation project must strictly enforce the "civil builduing external wall thermal insulation systems and external wall decoration fireproofing interim provisions" (referred to as "fireproofing interim provisions").

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: How long is the fire-fighting time of A class fire resisting window?: Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.

Q: How long is the fire resistant limit for ultra thin fire retardant coating?: 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 2, 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 less than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd.

Q: Who knows what kind of fire prevention materials are there?: Plant use general steel structure more often without too much modification. If there is a need for modification, boards which can meet the requirements of fireproof are suitable, such as gypsum boards and aluminium sheets. As for coating, it is favorable to use coating that has fine powder, high density and better sealing. Hardening agent mainly depends on the specific requirements.

Q: What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?: Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Of course, there are also some docks that need not be fumigated! But also according to the requirements of the port of destination guests, because customs clearance may be proof of fumigation!

Q: what textures of furnace refractories are good?: First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.

Q: Classification of porosities in refractories and their effects on properties: The pores in refractory include open pores, through pores and closed pores.
