Grinding Black Silicon Carbide

 

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials.  It is used for making bonded and coated abrasive tools, grinding metal and non-metal materials of lower tensile strength, such as gray cast iron yellow bronze,aluminum, stone, leather, rubber, etc.

Black Silicon Carbide with High Purity SiC made in China


Q: What are the materials of insulation firebricks?
The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
Q: Refractory net
I think China's refractory industry does exist high yield and quality is not high.The main reason, I think, is the immaturity of the Chinese government and individuals. First of all, the government does not encourage basic research, resulting in the lack of innovation in the refractory industry; moreover, the company and enterprise take immediate interests as the most important and do not value long-term development; individual enterprises are eager for quick success and instant benefit. Users of domestic refractories, refractory products only to the price for the bid by standard of foreign products; regardless of price, quite a bit of the meaning of things.
Q: What are the requirements of refractory temperature of refractory brick?
Refractory brick, called refractory?brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint?yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃ -1,770 ℃ high temperature.
Q: How much is the duration of fire resistance of the porous brick shale?
It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃.
Q: How to divided the grade of external wall thermal insulation materials?
1, According to China's national standard GB8624-97, combustion performance of building materials will be divided into the following grade level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high. 2, The external wall thermal insulation materials is divided by fire rating 1) level A combustion performance thermal insulation material Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope my amswers are helpful to you
Q: What are the filling refractories in door leaf of class A fire resistant door?
Magnesium chloride, magnesium oxide, perlite and other mixtures.
Q: The performance of refractory material
The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.
Q: What does refractory mean?
Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..Special materials often use AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so onUnshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
Q: What are the material requirements of class A fire resistant door ?
Refractory time should be no less than 1.5 hours.
Q: who knows the technology of fireproofing material?
1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof?panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
