Black Silicon Carbide is made by a precision water classification process and air flow classification using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.

Green silicon carbide is produced as the same type as the black silicon carbide,except the different raw materials. It’s crystallization have higher purity and hardness.Green silicon carbide is suitable for processing hard alloy,metallic

and non-metallic material with hard and brittle feature such as copper, brass, aluminum,magnesium,jewel, optical glass, ceramics, etc. Super micro-power of it is also a kind of ceramics material.

Q: Does the external wall thermal insulation materials level b1 need the fire barrier zone?: Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a horizontal fire barrier zone. 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone. According to this understanding, it can not be set.

Q: What's the maximum temperature that the refractory ceramic fiber cloth can endure?: Ceramic fiber cloth is high temperature resistant and its continous use temperature can be up to 1000℃. It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; and it is easy to install.

Q: The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide: 1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.

Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: The material is very troublesome, it might crack horrendously if not baked well and all of them may be scraps after being took out from the furnace. Magnesia hydration is inevitable during the baking process. As volume expansibility of magnesite reaches 200%, so it is easy to crack. The key to bake is to quickly rule out the water vapor in furnace, especially within 150 degrees Celsius. After quickly ruling out the water vapor in furnace to avoid excessive reaction with magnesia of 150 degrees, it can be operated in accordance with convention. In addition, you should pay attention to the heat sources, for which i recommend electrical and coke to avoid generating a lot of water vapor during the natural gas combustion process which will worsen the situation.

Q: Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?: You can try the following way to give a brief introduction of the fire?rating classification of external wall thermal insulation materials. 1. the building materials are divided into following categories in terms of combustion performance according to the national standard of GB8624-97. A-level： Incombustible building material: materials almost don't burn. B1-level: nonflammable building material: these materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building material: combustible building materials can play a certain role in flame resistance. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden column, timber roof truss and timber beam as well as stairs. B3-level: Inflammable building material: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1). Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2). The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene board(XPS)/ specially-treated polyurethane(PU), phenolic aldehydegelatine powder polyphenyl granule,etc. 3). Insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.

Q: What kind of refractories do the anode baking furnace use?: 5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.

Q: Detailed description of magnesia dolomite refractory material?: The use of low chromium or chrome free refractories is more and more widely used, developed countries in the development of chrome free refractories to replace the chromium containing material, through research and production practice show that dolomite refractories is the refining of AOD furnace, large cement kiln ideal material.

Q: how to classify the fireproofing material levels A1 A2 B1?: their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into

Q: Which refractory is suitable for the tunnel kiln?: The refractories produced by the following ten manufacturers are relatively good. They are all being the top ten brands! 1. king coconut (Chinese well-known trademarks, famous brand, the nation's largest manufacturer of wood panels, large building materials chain enterprises, Hangzhou king coconut Holding Group Co., Ltd.) 2.
