GREEN SILICON CARBIDE(GC)
Green silicon carbide is characterized by strong grinding efficiency and good heat-conductivity. Its hardness and strength are higher than fused alumina.
Applications:
1. Used to grind hard and brittle metal alloys, non-ferrous metals and non-metallic
materials like jewels,optical glass and ceramics.
2. Suitable for manufacturing vitrified wheels and belts, organic wheels and sheets.
3. Applied to refractory industry.
4. Powder of GC is also used as wire sawing semi-conductor raw materials.

- Q: What is the main constituent of refractory brick?
- There are several refractory bricks, including clay brick, carborundum brick and chromium-carbon. The type you said may be refractory bricks made from bauxite.
- Q: What does fire-resistant insulation coating have?
- Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature. Hope it is helpful to you.
- Q: How much modulus is used as refractories material of sodium silicate.
- Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate
- Q: What's the difference between refractory metal raceway and fireproof raceway?
- In terms of fire protection, fireproof raceway means that it is composed of the material with certain combustion performance and generally made of flame retardant or incombustible?material. While for the refractory raceway, according to GA 479-2004 "Fire Resistant Cable Tray", its most important properties are: Fire resistance of the cable tray should meet with the following requirements: The cable tray of I grade fire resistance should keep the working time more than 60min, of II grade fire resistance should keep the working time more than 45min, and of III grade fire resistance should keep the working time more than 30min. Hope this is helpful for you! Thank you.
- Q: what are the requirements of fireproofing material?
- answer: 1 fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc. 2, fireproof?panel is the most common texture in the market. There are two common types: One is the high pressure decorating refractory slab, it's advantages are fireproofing,moisture-proof, wear-resistant, oil resistant, easy to clean, and it has various colors; another one is glass magnesium fireproof board, external layer is decoration materials, and inner layer is mineral magnesium fireproofing material, and it can endure 1500 degrees high temperature but has bad decoration. Installing fireproof suspended?ceiling in outlet channel of construction, stairwell and corridor can ensure safe evacuation of people and protect people from attacking of fire spreading in the disaster. 3, the production process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
- Q: Refractory factory grinding brick dust harmful to the body?
- Therefore, in the workshop work must pay attention to do their own protection.
- Q: Does refractory belong to stone, building materials or other?
- It belongs to metallurgy and building material industries.
- Q: What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
