Product Description:

Black Silicon Carbide Carborundum

 

 

The Chemical Formula of Silicon Carbide, which is also known carborundum, is SiC. It is produced by the carbothermal reduction of silica to form an ultra-hard covalently bonded material.

 

Black Silicon Carbide (C)

It is used to grind cast iron, on-ferrous metals, rubber, leather, lactic, wood, mineral rocks, etc. It can also be used to manufacture high-class refractory products.

Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?
Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), sea capacity module and vitrified micro bead. (Hope I can help you! Hope you adopt. Thank you! )
Q:What's the fireproof specification for constrcution external wall thermal insulation materials?
Specification for constrcution external wall thermal insulation materials: Article 1 In order to implement the "State Council opinions on strengthening and improving fire prevention work" (state issued [2011] No. 46), to standardize fireproof design and application of external wall thermal insulation materials of newly constructed, renovated, and expanded civil buildings and to prevent and reduce fire of building external wall thermal insulation materials, this provision is made in accordance with relevant national technical standards and our province real situation. Article 2 When there is no cavity between external wall thermal insulation material for exterior wall and base wall and between decorative layers, the insulation system shall comply with the following provisions: (A) Residential buildings: 1. When the building is higher than 54m, combustion performance of the thermal insulation material shall be A level; 2. When the building is not higher than 54m,combustion performance of the thermal insulation material shall be at least B level. When using B1 level insulation materials, non-combustible materials should be used to make the protective layer, and a protective layer thickness of the first floor of the building should be not less than 10mm, the other floors not less than 5mm; incombustible materials of more than 300mm height should be used to make horizontal fire barrier zone in every floor. (B) Other buildings in addition to residential buildings
Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
(1) the height of buildings is greater than or equal to 24 m, the combustion performance of thermal insulation material should be A-level. (2) the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be A- or B1-level. When using B1-level thermal insulation materials, fire barrier zone should be set in each floor. (3) incombustible materials should be used as the protective layer of thermal insulation materials. Thermal insulation materials should be completely covered by protective coatings. The thickness of protective layer should be no less than 3 mm. (4) The base walls should be set in buildings with nontransparent curtain wall structures of metal, stone,etc. The fire endurance of which should comply with relevant provisions of current fire safety rules on fire endurance of external wall. The fire endurance and fire protection construction of pier between two windows, window sill walls, skirt walls of glass curtain walls should comply with relevant provisions of current fire safety rules on building curtain walls. (5) the internal cavity of base walls, as well as the space between the skirt wall and base walls, pier between two windows, window sill walls should be sealed with fire-proof sealing materials at each floor.
Q:What are the electrical fire protection materials?
Flame retardant organic resin: They can be classied into PVC, vinyl chloride, chlorinated rubber, epoxy resin emulsion, epoxy resin, phenolic resin, etc.. Fire retardant additive: Phosphorus and halogens, nitrogen organic compounds (chlorinated paraffin, tributyl phosphate (TBP) and polybrominated diphenyl ethers) and boron (boric acid, zinc borate, boric acid aluminum), antimony, aluminum, zirconium inorganic compounds.
Q:What's the frequently used refractory material?
Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory castables, etc.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
No In the high school chemistry, the former is talking about the traditional inorganic material, the latter is belonged to the new materials.
Q:The classification of fire-resistant material
There are various refractory materials classified according to the chemical properties of material: Min< manufacturing technique: neutral refractory materials, pipes, etc. Standard model: baidu.hiphotos;8 simatic carbon composite refractory material zirconia based refractory material special fire-proof material 6; or a acute angle of 50~70° and material forms. 3.
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
Q:What type of firebrick does TZ-3 represent?
Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.
