Abrasives Raw Material Green Silicon Carbide/Carborundum grit particle
1. Description:
Green silicon carbide is produced in the same way as Black silicon Carbide
except for some differences in raw material. Silicon carbide is an extremely hard
material (Mohs hardness 9.4), is chemically inert and does not melt. Silicon Carbide
has a high thermal conductivity, a low coefficient of thermal expansion, is thermal
shock and abrasion resistant and has strength at high temperatures.

- Q:What materials is silicious thermal insulation board made of?
- Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
- Q:What are the materials of class A fire resistant window?
- Fixed class A fire resistant window should be made up of steel frame, steel casement, and fireproof glass. Fire windows, made up of steel frame, steel casement, and fireproof glass, refers to window that isolate and stop the fire from spreading. Fire window is named according to the main materials of the frame and casement. Window frame is made up of steel and casement wood, vise versa. I hope it is useful.
- Q:Who can tell me the properties and classification of insulating refractories?
- The refractory materials refers to the refractory material of high porosity, low volume density, low thermal conductivity of the insulating material. Also called lightweight refractories. It includes insulating refractory products, refractory fiber and refractory fiber products.The characteristics of insulating refractory material is of high porosity, generally 40% to 85%; the volume density is low, generally less than 1.5g/cm3; the thermal conductivity is low, generally less than 1.0W (M - K). It is used as the insulation material of industrial furnace, furnace can reduce heat loss, save energy, and reduce thermal insulation equipment weight. The mechanical strength of refractory material, abrasion resistance and slag resistance is poor, should not be used for load-bearing structure of furnace slag, furnace, and direct contact with the molten metal and other parts.
- Q:what is the original materials of fireproof coating?
- Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium.
- 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:Who knows how to divide the building fire grade and fire resistance grade?
- I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
- Q:About the use of horseshoe glass kiln refractories
- the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric?smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.
- Q:which kind of refractory is commonly used in the industry
- Like silicon, magnesium calcium and metallurgy refractories, glass, silicon, etc., knowing the basic materials, and the businesses are not the same. I suggest that you can buy the refractory book to read.. Others include zircon, shapeless refractory material and so many other cement, such as magnesia, high alumina,ect.. Iron making is using the acidity material, continuous casting is using the clay, nonferrous metals and other types of more complex hot-press charcoal; steel making is using the alkaline, magnesium chrome, magnesium carbon, and clay,etc..
- Q:What are included in wall fireproofing material?
- External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincial records of production, provincial records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal mortar produced by it is recommend product of Department of Construction in Hebei Province!
