1.Description

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. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.

black Silicon Carbide

Description

Silicon carbide (SiC) is made from quartz sand and petroleum coke( or coal tar), wood chips as raw material through high temperature smelting in electric resistance furnace.

Applications

1.metallurgical deoxidizer

2.high temperature resistant materials

3.as abrasive, abrasive tools can be used to such as grinding wheels, whetstones, grinding head, sand tile etc

Advantages

1. corrosion resistance, high strength, high hardness,

2.good wear-resisting performance,resist to shock

3.stable chemical performance, high thermal conductivity, high resistant temperature

Q: A chemical problem with refractory materials: In chemistry, there is never absolute

Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports: Porosity, volume density, water absorption, true density, thermal expansion, thermal conductivity and heat capacity.

Q: how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q: Why does refractory need to add coarse firstly and then add fine aggregate?: Binding agent can wrap particles and improve binding effect.

Q: What is the new fireproofing standard of external wall thermal insulation materials?: The new national standard "Fireproof? Specification of Building Design" (GB50016-2014) has been issued, it will be carried out from May 1, 2015. Compared with "Fireproof? Specification of Building Design" GB 50016-2006 and "fire?safety?rules of tall buildings design" GB 50045-95 (2005 edition), the major changes of new standard is the following: 1. It has combined with "Fireproof? Specification of Building Design" and "Fireproof? Specification of Tall Buildings Design", and has adjusted incompatible requirements between two standards, and has unified the classification of residential buildings in accordance with the building height; 2. It has increased two chapters including the fire-fighting rescue facilities and wooden structures, and has improved the requirements for fire fighting and rescue, and standardized the fireproofing requirements of wood construction; 3. Additional requirements for the fireproofing requirements of building external insulation system; 4. The fire-fighting equipment is written in a separate chapter and improve relevant contents; cancel the design requirements of fire water supply system and smoke control system, and they are regulated by the relevant national standards; 5. appropriate increase in the high-rise residential buildings and fireproofing technical requirements for high-rise civil building whose height is greater than 100m; 6. add the fireproofing requirements used by covered pedestrian during evacuation; adjust and add designers density of construction materials, furniture, lighting shops and exhibition hall; 7. add the fireproofing requirements of underground warehouses, logistics buildings, large combustible gas tank (zone), ammonia storage tanks, LNG storage tank, and adjust the fire?separation distance of liquid oxygen tank; 8. improve the relevant requirements to prevent vertical or horizontal spread of building fire.

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Why is the apple screen so small?

Q: Who knows the roofing fireproofing and waterproof material?: If you should do home water proofing, I recommend the acrylate waterproof coating with high elasticity of Qinglong waterproof, because it has good aging resistance, extensibility, elasticity, binding property and film-forming property; waterproof layer is a closed system, the overall waterproof effects are very good, especially for the construction of heterotypic structure base and roofing, walls, toilet and bathroom, basement and other buildings waterproof and anti-seepage engineering in the conditions of non-permanent immersion;

Q: Development trend of refractory industry: In the central provinces in Henan, Shanxi, Liaoning China main manufacturer of refractory material, which is the main origin of three China bauxite, magnesite and other refractory materials; refractories industry by the end of May 2009 more than 3236 enterprises; industry revenue reached 67 billion 52 million 540 thousand yuan, Henan Province, Liaoning, Shandong, Jiangsu, Hebei and other regions, and refractories industry in the development of better leading enterprises, such as blue and white, accessible, prco etc. at present, its sales in the industry in the proportion is still small, the largest sales is also inadequate in refractory industry in 4%. An enterprise should play a leading role in leading enterprises in the industry, and its turnover in the industry should be more than 15%. Obviously, at present the refractory industry in the leading enterprises do not have, and the refractory industry concentration needs to be improved, and the existing resources in the refractory industry integration, is undoubtedly the way this process effective and efficient.

Q: Does the aluminum silicate thermal insulation material fireproof?: Yes, because of its low heat conductivity coefficient, and good thermal insulation, it can be setting fire.
