Silicon carbide
Products Description
With quartz sand and petroleum coke as its main raw materials, black silicon carbide is produced at high temperature in an electric resistant furnace. Its hardness is between corundum and synthetic diamond and its mechanical strength is higher than corundum, which makes it an ideal material for high quality abrasivetools.
Application
1. The most widely application of silicon carbide is producing abrasive tools, such as grinding wheels, cutting disks, etc. Black silicon carbide powder also could used as lapping and polishing media.
2. Black silicon carbide is suitable for processing glass, ceramics, stone, metal, rubber and other materials. 3. Black carborundum also can be used as metallurgical additive and high-grade SiC refractory material

- Q:How is the grading of the level A new material fire insulation material?
- The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal?mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement, which the Xuzhou Green Year EEB company's main produces.
- Q:Refractory factory grinding brick dust harmful to the body?
- The effect is very large and belongs to lung disease.
- Q:What is the definition and classification of amorphous fire resistance materials?
- 9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
- Q:What is refractory aggregate?
- Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.
- Q:Fire resistance and evaluation of refractory for casting
- The refractory degree of refractory material at high temperature is called refractoriness. Refractory products all contain substances from fusible sintering action, the melt crystal as unlike at a fixed temperature, but the temperature in a wide range. At a lower temperature, a small amount of melt is formed, and as the temperature increases, the amount of the melt increases, and the product gradually softens. Refractoriness and melting point (crystal) are different concepts.
- Q:What is acid refractory material?
- Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used. Neutral refractory is mainly composed of alumina, chromium oxide or carbon.
- Q:Who knows the setting requirements of roofing fire barrier zone?
- curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier?between?two?windows, window sill wall and skirt wall should be sealed by the fire-proof?sealing?material at each floor. I hope I can help you!
- Q:What is fire retardant coating mainly used for?
- The functions of refractory coating are as follows: 1. Non-intumescent fire retardant coating is mainly used for the fireproofing of wood, fiber board and other materials, and it is used in the surfaces of wood truss, roof, doors, windows and etc. Second, the intumescent fire retardant coating can be divided into non-toxic intumescent fire retardant coating, expansible fire retardant coating emulsions, solvent-based fire retardant coating. 3. Non-toxic intumescent fire retardant coating can be used to protect cables, polyethylene pipes and insulation board. 4, The expansible fire retardant coating emulsion and solvent-based fire retardant coating can be used for fireproofing of buildings, electricity power, and cables. 5. New fire retardant coating: Transparent fire retardant coating, water-soluble intumescent fire retardant coating, fireproof emulsion paint, polyvinyl acetate emulsion fire retardant paint, water-soluble intumescent fire retardant paint drying at room temperature, fire insulation coating polyolefin fire retardant coating, modified high chloropolyethylene fire retardant paint, chlorinated rubber fire retardant coating, firewall coating, intumescent coatings, wire and cable fire retardant paint, new fire retardant coating, casting fire retardant coating and so on.
- Q:which kind of material is chosen for fireproofing window?
- Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.
