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 and Low Price

Q: Which manufacturers have the best fire-proof materials with light weight?: Tinajin SPstar Insulation Material Co.,Ltd. is Chinese agent of German Berkson which is engaged in the application of field of high temperature and thermal insulation for many years and has accumulated experience of application of WDS nanometer scale micropore thermal insulation matrial in a variety of industries. Welcome domestic customers and experts in all industries to contact us and cooperate to promote this new energy-saving insulation materials. Make due contributions for China's energy-saving and sustainable development and low carbon emissions project!

Q: How much modulus is used as refractories material of sodium silicate.: Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate

Q: What are the meanings of azs, 34% and ec in fused brick?: The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.

Q: which kind of fire?bulkhead is better?: I think fire bulkhead is good, fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible?material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic.

Q: What's the refractory material?: Frequently used refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia. In general, the refractory material include the above. For more information, you can ask for specific advice.

Q: Who knows how to divide the building fire grade and fire resistance grade?: I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on.

Q: How long is the duration of fire resistance that fireproof door of level B can endure?: The national standard for fireproof door of level B is 1.5h, which must be achieved. The data GB12955-2008 means that the door leaf of raw material is 0.8mm-1.2mm in thickness and door frame is 1.2mm-1.5mm in thickness. And other metal melting temperature shall not be less than 950℃, the duration of fire resistance shall not be less than 0.9 hours. Fire department will check and accept based on the manufacturer's inspection report, so you have to refer to manufacturer's inspection report if you want to know more in detail.

Q: What is the fire endurance of fireproof glass cotton?: The highest temperature of fireproofing glass wool can be above 200 degrees, so it can be used for a long time,it's difficult to judge the special usage time, but its usually about 3 months and 8 hours every day.

Q: What is the interior fireproof thermal insulation material?: polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.

Q: About the use of horseshoe glass kiln refractories: the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric?smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.
