Q: What are the hazards of inhalation of graphite dust?: Personally think: black carbon on the human body, and the extent of the time has a lot to do with. On the human body caused by short-term damage is limited to a certain extent, can be restored (but the inhaled particles are difficult to be excreted); over the long term, great harm to the human body, but also can not be restored. Heavy inhalation of carbon black dust can at least cause carbon black, dust, and lung disease (occupational disease, pneumoconiosis). Included in the pneumoconiosis in China: silicosis, coal worker's pneumoconiosis pneumoconiosis, graphite, carbon black pneumoconiosis, asbestosis, talc, mica, cement pneumoconiosis pneumoconiosis pneumoconiosis, Potter's pneumoconiosis, aluminum pneumoconiosis, welders' pneumoconiosis, graphite pneumoconiosis etc.)! At present, the world's lack of treatment for pneumoconiosis, suffering from pneumoconiosis equivalent to sentenced to death. The number of pneumoconiosis patients in our country is equal to that of pneumoconiosis patients in other parts of the world. Please pay more attention to it and don't inhale any more

Q: What's the conductivity of graphite powder, silver powder?: These two values show that the resistivity of silver is small, so the conductivity of silver powder is better

Q: How to identify iron powder and graphite powder in a simple way?: Iron powder can be attracted by magnet, graphite powder can not; iron powder can react with acid, graphite powder can not wait, optional take first magnet attract, and then drip acid or hand touch method to identify two substances;

Q: What graphite powder made of graphite products, high hardness?! Wear-resisting！ Good moisture! It can be made into graphite products at 100-200 degrees high temperature: Graphite powder is divided into natural graphite powder and artificial graphite powder, graphite powder made of graphite products, you need to add binders, binders useful for a variety of resins, asphalt and so on.

Q: Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?: Reacting with oxygen at different temperatures to produce carbon dioxide or carbon monoxide; only fluorine in the halogens can react directly to elemental carbon;

Q: How to measure the iron content in graphite powder?: Take a certain amount of samples, adding dilute hydrochloric acid, excessive filtering and drying. The quality of the filter residue. By weighing the quality of the sample quality is the quality of minus slag containing iron. With this value divided by the sample quality, the mass fraction of iron.

Q: What binder does the graphite powder form with?: The commonly used asphalt in the industry is used as binder, and graphite powder and asphalt are mixed and pressed to form. It is also necessary to heat, roast and graphitized the asphalt in the graphite blocks to obtain certain heat conducting, conductive or other uses of Shi Mobang.

Q: How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways: Method two: Ignite (ignite in oxygen bottle)Iron sparks, release a lot of heat, and generation of black powderAluminum burns violently, gives off dazzling white light, emits a large amount of heat, and simultaneously produces white solidThe graphite powder is formed to clarify the turbid water of the lime waterMethod three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectively

Q: How can graphite paper be made? Can graphite powder be solidified without brittleness?: Process for the preparation of graphite paper: high carbon flake graphite, graphite by chemical processing into acid (also known as graphite oxide or expandable graphite), in high temperature 960 to 980 DEG C for a few seconds, the level of the graphite lattice moment along the C axis expansion, a fiber floc type vermicular graphite. The expanded graphite is very soft, the roller for the rolling forming, expanded graphite and flexible graphite sheet or foil sheet.

Q: The axis and drum can use graphite powder lubrication: This doesn't seem good. Graphite powder is a solid lubricant. It is suitable for heavy equipment lubrication. The axis and drum or low viscosity lubricating grease is better, so fast.
