wafer Silicon Carbide for abrasive  

Specifications:

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz 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 brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc It is also broadly used as refractory material and metallurgical additive

Q:How to apply the alumina powder on refractories?
The most common one in use is the refractory bricks.
Q:What kinds of fireproof materials does the safe use?
Copper is one of the most widely used material in safe, for its good mechanical performance, corrosion resistance and processibility and it has beautiful color. Especially handles, locks and other decorations forged of copper are smooth, pore-free, also they have good density, and no blisters. They are solid and rust-proof, which can get gilded with 24K gold or gulch-gold and have other surface treatments. A lot of colors have been added to people's home for the copper's magnificence and nobleness.
Q:what's the classification of fireproof materials?
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 Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
Q:What kind of materials are needed to make refractory bricks?
The components of the raw materials of refractory bricks. There are many types of raw materials, mainly divided into six categories: Earth, stone, sand, ore, powder and others. No.1, earth: bauxite, kaolin, clay, kieselguhr. No.2 Two: stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite and dolomite, sillimanite and spinel, silica. No.3: sand: ceramic sand, zircon sand, quartz sand, magnesia. No.4, ore: chrome ore. No.5, powder: Metal powder, silicon powder, metal powder. No.6, others: Asphalt and graphite, phenolic resin, perlite, cenosphere, sialon corundum silicon sulfate, silicon carbide, water glass, silica sol, boron carbide, calcium aluminate cement, nitride materials, shale ceramsite, alumina, aluminum sol, zirconia.
Q:Who knows the model of fireproofing materials?
Models of fireproofing material: PC 6555 Bayer 6555 fireproofing PC 6557 Bayer 6557 fireproofing PC 6485 Bayer 6485 fireproofing PC 6385 Bayer 6385 fireproofing PC 6265 Bayer 6265 fireproofing PC 2865 Bayer 2865 fireproofing PC 4610 Dow 4610. Hope my answer will be helpful to you!
Q:How to distinguish the construction fire-proof material rating?
Each country has its own fireproof standards, so I do not know which country you are in ? Each country has different division levels of fireproof materials, such as GB 8624, German standard DIN 4102-1, British standard BS 476, France standard NF P92-501 and so on. GB 8624 Chinese building materials and products combustion performance division levels fireproof resources network (FireTC.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Hello. 1. Gaps between the curtain walls and floors of all tier and partitions outer edge should be sealed with non-combustible material or flame retardant materials. Filling material can be rock wool or mineral wool, whose thickness should be not less than 100mm and should meet the designed fire endurance requirements, forming fire and smoke prevention areas between floors and rooms. Fireproof layer should use galvanized steel bearing with thickness of not less than 1. 5mm, and should not use aluminum plate. Gaps between bearing plate and main structure, curtain wall structure and the bearing plate should be sealed by fireproof sealant; fireproof sealant should has fireproof inspection reports granted by statutory testing organizations. 2. When building designs requiring transparent effect of fire compartment and separation, monolithic fire-resistant glass or hollow and laminated fire-resistant glass nade by monolithic fire-resistant glass can be adopted. 3. Windowsills-free curtain walls, incombustible entities skirt wall or fireproof glass wall whose fire endurance is not less tan 1.0 hour and height is not less than 0.8m should be set on the outer edge of each floor. The thickness of reinforced concrete floor or height of the side beams should be counted when calculating the height of the skirt wall. 4. Fire protection layer should not contact directly with the glass curtain wall, and the side towards the glass of fireproof materials should be covered with the decorative material. 5. Glass units of the same curtain wall should not cross two fire compartments.
Q:What refractories are used in various parts of the blast furnace.
Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon carbide brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory includes metallurgical auxiliary materials.
Q:What are the insulation fireproofing materials?
Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.
