Product Introduction:
Due to chemical stability, high thermal conductivity, low thermal expansion coefficient, good wear resistance, in addition to abrasive use, Silicon carbide can be used in many ways,
1) As abrasive, can be used for abrasive tools, such as grinding wheel, oilstone, grinding, sand tile etc.
2) As deoxidizer and high temperature resistant material.
3) Silicon carbide powder coating on the inner wall of turbine impeller or the cylinder body, to improve and extend the service life of 1 ~ 2 times for its wear resistance;
4) As the single crystal of high purity, can be used for manufacturing semiconductor, silicon carbide fiber.
5) Advanced refractory material, made from which, has thermal shock resistance, small volume, light weight and high strength, and good energy saving effect.
6) Low grade silicon carbide (SiC 85%) is an excellent deoxidizing agent, which can be used to speed up the steel-making, and easy to control the chemical composition, improving the quality of the steel.
7) Silicon carbide is also used extensively for production of silicon carbide heating elements.
Application

2. Heating elements
3. Coated tools
4. Refractory
5. Polishing ,Lapping
6. Ceramic
- Q: Does anyone know the characteristics of refractory for glass kiln?
- Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
- Q: Can anyone tell me what material the first rate fire resistant door is?
- Material of Class A fire doors can be divided into steel and wood, so fire doors can be divided into fireproof steel door and fireproof wooden door. In fact, fire doors of all classes are divided into steel, wood, steel and wood, and other materials (see GB ). Mainly depending on what kind of material the customers want. The fire door is called class A fire door not because of the material but because of the fire-resistant time. The fire resistant time of class A fire door is not less than 1.2 hours and fire doors as long as meeting this condition can be called class A fire doors . The filling material in class A fire doors is generally perlite, whose difference is in thickness. A few of them will use fireproofing materials like foam core board, vermiculite fireproof board, MC composite material and so on. The thickness of class A fire door is usually 50mm. I hope my answer can help you.
- Q: Refractory material, refractory brick
- 1, according to the degree of refractoriness:Ordinary refractory material: 1580 ~ 1770 DEG CAdvanced refractory material: 1770 ~ 2000 DEG CSuperfine refractory material: >2000 DEG C2, depending on the shape and size of the product:Standard type: 230mm * 113mm * 65mm;No more than 4 measurements, (size ratio) Max:Min<4:1;Profile: no more than 2 concave, (size ratio) Max:Min<6:1;Or an acute angle of 50~70 degrees;Specific type: (size ratio) Max:Min<8:1;Or not more than 4 or a sharp angle; 30 ~ 50 degrees;Special products: crucibles, vessels, tubes, etc.3, according to manufacturing methods, refractory materials can be divided into:Fired products, unfired products, unshaped refractories4. classification according to the chemical properties of materials:Acid refractory material, neutral refractory material, basic refractory material
- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name, hope you adopt.
- Q: What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
- there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
- Q: How to deiron refractory?
- It cannot be done in conventional approaches, because you are referring to refractories. If using acid liquor soaking method to deiron, the material itself will be also damaged! If just for reducing the corrosion of materials, it will be OK to add a corrosion-resistant and fireproof protection layer.
- Q: who knows the fire resistant level of fireproof gypsum board ?
- The most commonly used ceiling decoration materials rates B1, including gypsum board, fibrous plaster, cement particle board, mineral wool sound-absorbing panels, glass wool decorative acoustic?panel?absorber, perlite decorating acoustic board, nonflammable plywood, nonflamable medium density fiberboard, mineral wool decorative board, flame retardant wood, aluminum foil composites, flame retardant phenolic plywood, aluminum foil glass fiber reinforced plastic composite materials. The fire gypsum board fire rating can reach A. Of course, many of the suspended ceiling gypsum board of inferior quality rates below B1. plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. plaster board mounted on steel stud can be used as A level decoration materials. in accordance with the national fire safety rules on fire durance of walls and ceilings and other components. we can not simply say whether a piece of gypsum board can meet the requirements.
- Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
- What thermal equipment? The most simple principle is durable, low cost and with no environmental pollution.
- Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
- There are two kinds: 1, the thickness of the plate is between 20 ~ 50 mm with composite structure 2, sheet thickness is between 6 ~ 15 mm calcium silicate fire prevention board.
- Q: Who knows about the types of Dalian thermal insulating and refractory materials?
- (1) rock wool board: the heat conductivity coefficient is 0.041-0.045. It is fire retardant, has a great temperature absorption while a poor thermal insulation performance. (2) glass wool: it is simple in construction and free in cutting. It has advantages of antibiosis, mould proof, aging resistance and anticorrosion, and can ensure a healthy environment. It has a low hygroscopicity and a stable physical property. (3) expanding polystyrene board(EPS board): thermal conductivity: 0.037-0.041, it has a good thermal insulation performance, cheap price but a poor intensity. (4) extruded polystyrene board(XPS board): thermal conductivity: 0.028-0.03, it has a better thermal insulation performance, high intensity, moisture resistance while it is expensive, and requires surface treatments during construction. (5) gelatine powder polyphenyl granule heat insulating slurry: heat conductivity coefficient: 0.057-0.06, it has a good flame resistance while a poor thermal insulation performance, as well as has high construction requirements and can be recycled. (6) polyurethane foam: heat conductivity coefficient: 0.025-0.028, it has advantages of waterproofness, thermal insulation, high intensity, high integrity, and good integrity, but it has a poor fireproof?performance and is more expensive. (7) rigid polyurethane: heat conductivity coefficient: 0.018-0.023, it has advantages of low heat conductivity coefficient and good thermal performance. When the unit weight of rigid polyurethane is 35 to 40kg per cubic meters, it is equivalent to half of the EPS. It is the one with the lowest heat conductivity coefficient among all the thermal insulation materials. (8) perlite slurry: heat conductivity coefficient: 0.07-0.09, it has advantages of fire and high-temperature resistance, and high water absorption but is poor in thermal insulation.
