Product Description


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 sharp and

has electrical and heat conductivity in some degree.

 

2. Application

 

As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding wheel, sand

 tiles etc.

As the metallurgical deoxidizer and high temperature material.

Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and

 metallurgical materials.

High purity single crystal, used to manufacture semiconductors, manufacture of silicon carbide fibers.

Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high

temperature resistant to oxidation.

Q:What are the construction fire-proof materials?
1. fire retardant coating 2. fireproof panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
Q:Pals who know something about fire resistant material please tell me how many types of refractory material there are
There are a variety of refractory materials, each of different use. It is necessary to make resonable classification for refractory materials so as to facilitate scientific research, rational selection and management. There are many kinds of classification methods for refractory materials, including classification based on chemical property, chemical mineral composition, production process, material form and other methods. 1, according to the capacity of fire resistance: ordinary refractory materials: 1580 degrees C ~1770 C Advanced Refractory Materials: 1770 degrees ~2000 degrees c: Classification according to product shape and size: standard 230mm×113mm×65mm no more than 4 scales
Q:What's the fire endurance of fire windows?
Fire endurance of fire doors and fire windows stipulated by the fire prevention norm: Fire endurance of A class fire door or fire window is 1.2h rather than 1.5h, and fire endurance of B class fire door or fire window is 0.9h rather than 1.0h. Fire prevention code doesn't explicitly state that the fire door has thermal insulation function, so it can definitely be interpreted that the fire door only has fire integrity. For the fire door without heat-shielding performance, at certain distance from the unexposed surface, it has strong thermal radiation and is easy to hurt people. For the A class thermal insulating fire door, its fire integrity is 0.1h shorter than that of the corresponding fire door stipulated in the specification, but its heat-shielding performance and integrality is improved. All in all, compared with the specification that the fire integrity of the A class fire door should be 0.6h, it has much more improved its performance.
Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
Well, you have no furnace to cast disposable molds. You can sieve sand which is used for blending cement with siever (left the most fine behind)! And then you can go to hardware (parts) factories directly with molds to ask them to pour. Remember that brass (60 copper) needs to be heated to 1200 ℃, while the crucible is not needed.
Q:How long is the duration of fire resistance that fireproof door of level B can endure?
The national standard for fireproof door of level B is 1.5h, which must be achieved. The data GB12955-2008 means that the door leaf of raw material is 0.8mm-1.2mm in thickness and door frame is 1.2mm-1.5mm in thickness. And other metal melting temperature shall not be less than 950℃, the duration of fire resistance shall not be less than 0.9 hours. Fire department will check and accept based on the manufacturer's inspection report, so you have to refer to manufacturer's inspection report if you want to know more in detail.
Q:hat kind of fire retardant materials are there
fire-retardant materials include phosphorus chlorine, bromine and antimony, aluminum, boron based flame retardant, nanometer magnesium hydroxide, high purity industrial grade magnesium hydroxide flame retardant, high purity industrial grade modified magnesium hydroxide flame retardant, composite flame retardant magnesium hydroxide, aluminum hydroxide flame retardant, modified aluminum hydroxide flame retardant, light magnesium-oxide, unsaturated resin flame retardant, silicone rubber flame retardant, polyamide flame retardant, PE flame retardant, PP Flame Retardant, PVC flame retardant, wood flame retardant, special flame retardant for paper, CPE flame retardant, fabric coating rubber flame retardant, flame retardant carpet adhesive, water based coating flame retardant, oily coating flame retardant, power coating flame retardant, ink flame retardant, and heat stabilizer.
Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
It is difficult to distinguish from appearance. Their fire endurance are also different. The filling refractories of grade A and Grade B fire resistance steel doors are all perlite. The only difference lies in the filler compaction density.
Q:What is the classification standard of fireproofing material levels?
Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion source. Class B2: Combustible building materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
Q:Can you tell me the classification of fireproof sealing material.
Fire blocking is to use fire blocking material as partition between cable threading hole and electric hole. Its role is to prevent the cable itself catacausis or outside naked light make the fire spread to achieve the purpose of protecting the safety of personnel and equipment. The principle of fire-proof sealing is plugging material acting as bloating heat absorption and heat insulation. Fireproof sealing material in current market include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. The wide usage of fire-proof sealing material in building construction can ensure the fire flame and high temperature flue gas not to extend another fire partition tendril.
Q:How long is the fire endurance of Grade A fire resisting shutter
The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of  closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
