SIC 92 High Purity Black Silicon Carbide / SIC

Product name	Silicon Carbide (Carborundum ) / SiC / Black Silicon Carbide / Green Carbide Silica
Model No	BA-20#
Brand name	BA,CHINA
Description	Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke. Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity. Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive.

If you’ve Silicon Carbide enquiry, please don’t hesitate to let us know. ^_^

Q: What is the role of adding chromium oxide green in unshaped refractory materials: Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.

Q: How to divide the fire resistant level of EVB?: According to the indicators of amount of smoke, heat value, burning rate, and ignition point, combustion performance insulation materials are divided into A (non-combustible), B1 (flame retardant), B2 (flammable), B3 (combustible). It can be divided into the organic and inorganic types: The organic includes polyurethane and polystyrene board, the inorganic the includes glass wool and rock wool. The price of organic is lower, and it is combustible materials, it will produce hydrogen cyanide and other toxic gases when burned, the inhaled would die. The inorganic material is completely non-combustible insulation material.

Q: How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?: Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q: How to divide the materials according to the National Fireproofing Material Standard?: Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.

Q: How to distinguish the fire?rating of rubber and plastic thermal insulation material?: According to GB 8624-2006 "building materials and combustion products classification", the division of the material's combustion performance grade is changed from five levels of level A (homogeneous material), A (composite sandwich material), B1, B2 and B3 to seven levels of A1 , A2, B, C, D, E and F or A1f1, A2f1, Bf1, Cf1, Df1, ef1 and Ff1 or A1L, A2L, BL, CL, DL, EL and FL . The level B1 rubber and plastic fireproof and thermal inuslation matertial is the best, but the most commonly used one is level B2. Hope it will help you.

Q: What are the technical requirements for refractories?: How high the temperature is and what is this refractory?

Q: Who knows how many kinds of fireproof insulation materials are there in the market?: Portland cement, insulation stone, calcium powder and platycodon grandiflorum are the main raw materials of inorganic active insulation materials. Advanced manufacturing techniques and chemical Technologies have been used to conduct many tests, thus the close-celled inorganic active insulation materials are successfully developed. Products have advantages of fire-resistance, small deformation coefficient, aging-resistance, stable performance, environmentally-friendly, and good compatibility with rendering coating and subtractive wall, security, stability, and also have a life as long as the building itself. Good fireproofness: The materials of fireproof insulation board are inorganic (cement) which has A1-level fire-resistance, are non-combustible materials, and good at resisting fire. I hope my answer can help you.

Q: How should fireproof building materials be ranked?: 5. Civil building 5.1. Fire resistance rating, number of layers and floorage of civil buildings 5.1.1. Fire resistance rating of civil buildings should be classified into four levels of first, second, third and fourth. Unless otherwise specified in the code, the combustion performance and fire endurance of building components with different fire resistance rating should be no less than that of the regulations in Table 5.1.1. Table 5.1.1: Combustion Performance and Fire Endurance (h) of Building Components (Figure) Note: 1. Unless otherwise specified in the Code, the fire resistance rating of the building with wooden pillars as load-bearing and incombustible material as the building wall should be the fourth level; 2. For the suspended ceiling of the building with the second level of fire resistance rating, if it uses non-combustible component, it won't be limited in its fire endurance; 3. For buildings with the second level of fire resistance rating, if it is really difficult for the partition wall of rooms with the area of no less than 100m2 to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.3h; 4. For buildings with the first or second level of fire resistance rating, if it is really difficult for the partition wall of both sides of the evacuation walk to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.75h. 5. Fire endurance and combustion performance of the residential building component can be implemented in accordance with the provisions of current national standard GB 50368 "Residential Building Code".

Q: Who knows the new fireproof and thermal inuslation matertial?: Ceramic foam insulation board, XTP vacuum insulation panels and a variety of composite insulation panels, etc. Relatively speaking, the inorganic insulation board is a trend. In terms of the overall performance, the cost performance of the foam insulation board is higher. XTP has the best performance, but with a little trouble in construction. Because of the vacuum characteristics, transportation and installation process should be very careful.
