It is used in the fields of semiconductors, lightning rods, circuit components, high-temperature applications, ultraviolet detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic membranes, cutting tools, heating elements, nuclear fuel, jewelry, steel, protective gear, catalyst carriers and so on.
abrasive
Mainly used for grinding and polishing grinding wheels, sandpaper, abrasive belts, oilstones, grinding blocks, grinding heads, grinding pastes, monocrystalline silicon, polycrystalline silicon and piezoelectric crystals in electronic industry.
chemical industry
It can be used as a deoxidizer for steelmaking and an improver for cast iron structure, and can also be used as a raw material for manufacturing silicon tetrachloride, which is the main raw material for silicone resin industry. Silicon carbide deoxidizer is a new powerful compound deoxidizer, which replaces the traditional silicon powder carbon powder for deoxidization. Compared with the original process, the physical and chemical properties are more stable and the deoxidation effect is good, which is of great value for shortening deoxidation time, saving energy, improving steelmaking efficiency, improving steel quality, reducing consumption of raw and auxiliary materials, reducing environmental pollution, improving working conditions and improving comprehensive economic benefits of electric furnace.
"Three-proof" materials
Silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity and impact resistance. On the one hand, silicon carbide can be used for various smelting furnace linings, high-temperature furnace parts, silicon carbide plates, linings, supports, saggers, silicon carbide crucibles and the like.
On the other hand, it can be used for high-temperature indirect heating materials in nonferrous metal smelting industry, such as vertical tank distillation furnace, distillation furnace tray, aluminum electrolytic cell, copper smelting furnace lining, arc plate for zinc powder furnace, thermocouple protection tube and so on. Used for manufacturing high-order silicon carbide ceramic materials with wear resistance, corrosion resistance and high temperature resistance; It can also be used to make rocket nozzles and gas turbine blades. In addition, silicon carbide is also one of the ideal materials for solar water heaters in expressway and aviation runways.
nonferrous metal
Silicon carbide has high temperature resistance, high strength, good thermal conductivity and impact resistance, and can be used as high-temperature indirect heating materials, such as retort, distillation tray, aluminum electrolytic cell, copper smelting furnace lining, arc plate for zinc powder furnace, thermocouple protection tube, etc.
steel
Using the characteristics of silicon carbide, such as corrosion resistance, thermal shock resistance, wear resistance and good thermal conductivity, it is used for lining of large blast furnace to improve its service life.
Metallurgical beneficiation
The hardness of silicon carbide is second only to that of diamond, and its wear resistance is strong. It is an ideal material for wear-resistant pipes, impellers, combustion chambers, cyclones and hoppers, and its wear resistance is 5-20 times that of cast iron and rubber. Def is also one of the ideal materials for aviation flight runway.
Building materials ceramic grinding wheel industry
Using its characteristics of high thermal conductivity, heat radiation and high heat intensity, manufacturing thin-plate kiln furniture can not only reduce the volume of kiln furniture, but also improve the loading capacity and product quality of kiln and shorten the production cycle. It is an ideal indirect raw material for firing and sintering ceramic glaze.
conservation of energy
Using good thermal conductivity and thermal stability as a heat exchanger can reduce fuel consumption by 20%, save fuel by 35% and improve productivity by 20-30%, especially for the internal placement of discharge pipes in mine concentrator, and its wear resistance is 6-7 times that of ordinary wear-resistant materials.
Abrasive particle size and its composition conform to GB/T 2477-83. The determination method of abrasive particle size composition is GB/T 248 1-83.
jewels
Synthetic silicon carbide, also known as synthetic moissanite and synthetic silicon carbide (chemical composition SiC), has a dispersion of 0. 104 greater than that of diamond (0.044) and a refractive index of 2.65-2.69 (2.42 of that of diamond). It has the same diamond luster and stronger "fire color" and is closer to diamond than any previous imitation. This product is manufactured by C3 Company in North Carolina, USA, and has patents for the production of synthetic silicon carbide in all countries of the world, and is being popularized and applied worldwide.
What is the industry category of Shanghai Space Agency? Industry category: Aerospace.
Just look at the business license.
What is the industry category of catering? Is the service industry.
What industry category does underground parking belong to? The industry category of underground parking lot mainly depends on the camp type of enterprise living area, whether it belongs to the industrial park or not. The supporting facilities in the industrial zone refer to the necessary auxiliary facilities for production and living in the industrial zone, including single dormitory, staff canteen, industrial office building, warehouse, etc. For industrial areas, the most important supporting facilities are single dormitories. There are two kinds of land for single dormitory. The first is a single dormitory area built in pieces outside industrial land, with certain living facilities and relatively independent living and living functions. In land statistics, three types of residential land (R3) should be included in the statistics, and the planning and construction should be carried out according to the relevant standards of residential land. The second type is a single dormitory building built in Class I and Class II industrial zones for the convenience of workers' commuting, but it also needs to be built separately and may not be mixed with industrial buildings.
When designing, necessary health and environmental protection measures should be taken to meet the requirements of residential building spacing; This kind of single dormitory should be included in the industrial land (M) when making land statistics. Simply put, if it belongs to the family area, then
Generally, it belongs to the second-class residential land, and the underground garage belongs to the second-class residential land, not the road land.
