Q:Know how the colloidal graphite powder comes in: There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.

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:Is the graphite electrode broken like graphite, fossil oil, coke and graphite powder?: The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.

Q:The graphite powder production process and the graphite production process are introduced briefly Graphite powder production process, graphite production process, detailed technical parameters where?: In the process of crushing, the external force applied to the solid has four kinds of rolling, shearing, impact and grinding.

Q:Does the pencil core go into the baby's face to keep the skin tight?: One possible problem is that even if there is no breakage, but there may be residual graphite powder cartridge inside, more so, good after the wound will leave behind a black spot (a little like the indistinct).

Q:What solvent can be used to dissolve Teflon?: Market suspension of PTFE fine powder. It can be mixed directly with graphite powder without dissolving. It can press molding and sinter products.

Q:Which shipping company can pick up the name of graphite? Graphite products are mainly exported to India, Italy and the United states!: Graphite is neither a liquid nor a dangerous substance. There is no excuse for not answering it.

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:Is battery capacitor powder dangerous?: Graphite is very soft, creamy feel. It has excellent electrical conductivity. Color steel gray or gray, with metallic luster, with lubrication, easy dyes, chemical stability, heat conductivity, good heat resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, due to its small crystal plasticity, good adhesion, so it does not belong to the dangerous goods!

Q:How to deal with graphite powder? Anyone recycle it?: We have a lot of graphite, and now we have it
