1.Structure of Silicon Carbide Description
Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.
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.
2.Main Features of the Calcined Bauxite
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.
3.Main usage of the Calcined Bauxite
1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials
2.Bonded abrasive tools, lapping and polishing
3.Widely used as a metallurgical additive and refractory material

- Q: what's the standard of fireproofing material?
- Class A1 is divided according to the combustion performance of GB8624-2006 building materials and products. Specific technical index requirements are: 1, the temperature rise ≤30 degrees;mass loss rate ≤50%; combustion duration time is 0; 2, main components, overall products, gross calorific value of external secondary components ≤2.0MJ/kg; any inner secondary component ≤1.4MJ/kg; (there are difference between homogeneous and non-homogeneous). Z802 building materials noninflammability testing furnace has to be used for testing technical indicators mentioned in test 1, using Z805 building materials combustion heat value to test technical indicators mentioned in test device 2.

- Q: Who knows the setting requirements of roofing fire barrier zone?
- First, the the minimum of fire barrier width is greater than 30cm, and the thickness should be same to the thickness of the insulation materials. Fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. Fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. Second, Fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. The thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Third, When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. Flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. I hope you can be satisfied
