24 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.

abrasive white fused alumina (WFA) for sand blasting 24mesh

Q: Can anyone tell me what material the first rate fire resistant door is?: Class A fire door materials are mainly steel, wood, steel and wood,and other materials. If there is filling material in a Class A fire door, it is generally the perlite. According to the actual situation in China, the fire doors and windows are divided into class A, class B, class C, whose minimum fire endurances are stipulated, namely class A 1.50h, class B 1.00h, Class C 0.50h. There are fireproof wooden doors and fireproof steel doors. whose main purpose is to achieve fire endurance time. But door closers are required to be installed.

Q: How long is the duration of fire resistance that fireproof door of level B can endure?: Fireproof doors can be divided into three levels, namely level A,B,C. Fireproof doors of level A can endure fire for 1.50～2.00h while level B for 0.50～1.50h. However, according to national condition, the lowest fire doors fire resistance limit has been specified, namely, level A,1.50h;level B,1.00h; level C, 0.50h.

Q: Which kind of external wall fire barrier zone material is better?: I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical?plate arranged fiber technology to make the compressive?strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.

Q: What is the particle size of boron carbide for refractories?: 2 floor is right, support, learning! But what do you mean by boron carbide (d90=36.5, m)?

Q: Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?: There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.

Q: What 's the highest temperature can magnesium plate glass resist ?: You only need a fire-resisitance board thicker than 10 mm, remember to add more perlite as filler during production, 12 mm board is 80 yuan. . . .

Q: What refractories can withstand high temperature above 2100 degrees?: It depends on refractoriness of refractory materials. The three refractory bricks above is 300 degrees higher than quartz sand in refractoriness. Magnesia brick: Cast corundum brick with greater than 2000 degrees refractoriness should be enough for you to use. But products like quartz sand merely keeps 1600 to 1700 in refractoriness generally. As you described that refractoriness is greater than 1990 degrees, it is feasible to use hearth made by mixing of quartz sand and refractory cement, which can work for some time at 200 degrees. It is also ok to use dolomite brick whose refractoriness is greater than 2000 degrees.

Q: What are the specifications of fireclay bricks?: Standard sizes of refractory bricks in our country are: 230mm × 114mm × 65mm; standard density: 1, Diatomite insulating bricks 0.7 g / cubic centimeter; 2, Clay bricks 2.9 g / cubic centimeter; 3, High alumina brick 3.2 g / cubic centimeter. You can convert according to the actual volume, and the reference value can be calculated.

Q: Who knows how many poured refactory material are there?: Pouring refractory material can be classified into the followings according to the body density: Heavy (> 2.0g\cm3), medium heavy (1.0-2.0g\cm3), light (0.4-1.0g\cm3); by binding agent: Combination of hydration, chemical binding, condensation, hydration and condensation: Clay, high alumina, silica, magnesia, alumina magnesia, magnesium and chromium, magnesium zirconium, silicon carbide etc.. Clay brick, high alumina brick, bead brick, silica brick, light mullite, alumina hollow spherical brick, oxidation zirconium hollow spherical brick, corundum brick, magnesia brick, magnesia brick, magnesia alumina spinel brick, magnesia chrome brick and so on

Q: How to divide the fire resistant level of construction thermal insulation materials?: Combining three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division. And it is mainly determined in accordance with the national standard GB8624 Building materials combustion levels.
