Application of natural flake graphite powder:
1. Graphite with excellent electrical conductivity, thermal conductivity: Graphite’s conductivity is higher than the general non-metallic minerals a hundred times. Graphite’s thermal conductivity is much better than steel, iron, lead, and other metal element materials. With the great properties, graphite powder is widely used as electrode, the positive brushes, carbon rod, carbon tubes, mercury positive converter, graphite gaskets, phone parts, television picture tube coatings in the electrical industry as a manufacturer.
2. natural flake graphite powder is also a good lubricating additive powder. The performance of lubrication depends on the size of the graphite flake graphite, the larger of the flake the smaller of the coefficient of friction and lead to the better lubrication.
3. natural flake graphite powder is stable powder at room temperature, graphite is acid, alkali and corrosion resistance and also resistance of organic solvents.
- Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?
- external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class B1: nonflammable building material: non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Class B2: combustible?building?materials: flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs.
- Q: Refractory materials are needed for casting metallurgy.
- High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.
- 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.
- Q: What are the types of advanced refractory?
- Divided into ordinary and special refractory two categories. Common refractories by chemical properties into acidic, neutral and alkaline. Special refractory are divided by the high temperature oxide, refractory compounds and high-temperature composite materials by its compositions. according to refractoriness it can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and premium refractory products (2000 ℃ above). The article can be divided into blocks (standard bricks, shaped bricks, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron carbide quality, etc.) and irregular shape (refractory clay, pouring materials and ramming mixes, etc.) According to the sintering process is divided into sintered products, cast products, melt blown products. The appearance is shaped or amorphous according to pH it can be divided into acidic, neutral and alkalinity according to basic operation mode, there are castable refractory ramming spraying materials, impressionable plastic material, coating. according to different components, there are clay, high alumina, corundum, spinel, magnesia, magnesium, calcium, magnesium aluminum quality,magnesia-chrome, silicon, etc.
- Q: Who knows the highest temperature the high-temperature refractory coating can resist?
- The fire endurance of high temperature fire resistant coating is 3 hours. The fire endurance of fireproof is to go on fire resistance test of any building component according to the time- temperature standard curve, which is the period of time started from being put on fire and ended when losing support function or integrity has been destroyed or losing fire insulation function, expressed in hours. I hope my answer can help you. Thank you.
- Q: what is the Specifications Grading for Fireproof rubber insulation materials ?
- At present, China Building Materials has two grading criteria for combustion performance. "Combustion Performance Classification Method of Building Materials" and "Combustion Performance Classification Method of Building Materials and Products" (GB8624-2006). Among them, one of the major changes of GB8624-2006 and GB8624-1997 is to divide the material combustion performance grading from homogenous material)Class A (composite sandwich material), B1, B2 and B3 level five minutes as A1, A2, B, C, D, E, F seven levels.
- Q: Who knows the fire endurance of B-level fireproof doors and windows?
- According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. Fire endurance of fireproof windows: A-grade fireproof windows are not less than 1.5h and B-grade fireproof windows are not less than 1h. The door leaves of A-grade and B-grade fireproof windows should be steel materials, and their glass should be composite fireproof glass whose thickness is no less than 26mm. Monolithic fireproof glass window is not B-grade fireproof window, nor A-grade fireproof glass window. It si called non-insulated fireproof window.
- Q: Which refractory is better for building 1500 degree kiln ?
- The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
- Q: How long is the fire endurance of fire resistant rolling shutter door?
- According to fire endurance, fire doors can be divided into Class A, Class B and Class C fire doors, whose fire resistance should be no less than 1.20h, 0.90h and 0.60h respectively. You can use fire resisting shutters to seperate fire?compartments in places where it is difficult to set firewalls. When using the fire resisting shutter with unexposed surface temperature rise as fire endurance conditions, its fire endurance should be no less than 3h. But when using the fire resisting shutter without unexposed surface temperature rise as fire endurance conditions, you should set independent protection of closed automatic water spray system at two sides of the shutter, and the duration of water spraying should be no less than 3.0h. I hope it's useful.
- Q: Refractory inquiries
- Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
