18 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

Flexible price policy

Equipped full line of test method.

Brilliant produce&supply&delivery ability

We passed the certification of ISO9001:2000

White fused alumina has Al2O3 content 99% min

All products will be supplied according to customers different requirement.

The laboratory is certified by government Inspection Bureau, that assures its quality stability.

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 shapeless refractory with high performance?: The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.

Q:What are included in fireproofing materials?: There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire?retardant material and its products, textile, fire?retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof?panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof?sealing?material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of?toxic?gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire?rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.

Q:What are the construction fire-proof materials?: 1. fire?retardant?coating 2. fireproof?panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials

Q:Which one is better, fire-resistant wood or steel?: From the aspect of low-carbon and environment protection, the steel and timber structures are both OK, they are both renewable resources, the steel can be recycled and melt down again and wood can continue to be planted. Fireproof board Fireproof board is a refractory material used for surface decoration. It is widely used in interior decoration, furniture, kitchen cabinets, laboratory tables, walls, and other fields.

Q:Why can aluminium hydroxide not be used to make refractory material?: Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.

Q:Who knows the fire endurance of rock wool color plate?: Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof? Specification of Building Interior Decoration?Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .

Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.: The refractory that you want is high temperature furnace which you can buy from the market.

Q:What substitutes are available for high-end refractories in addition to zircon sand?: Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..

Q:How many kinds of fireproof materials are there in the market?: A-level materials are the best which will not burn while the B-level materials are made of combustible materials which can burst into flames.
