- Q:How do you use graphite powder in copper?
- It is to drill holes on the copper block and pour the graphite into the hole to ensure that the stone toner can not run out and play the role of oil-free lubrication
- 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:Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you
- The first kind, with magnet, can be sucked up is iron powder. Second kinds, high temperature melting, the first melting is iron powder
- 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:What is the use of flake graphite in making flake graphite powder?
- Flake graphite is widely used in advanced refractory materials and coatings of metallurgical industry. Such as bricks, crucible etc.. Military industrial explosive materials stabilizer, smelting industrial desulfurization growth agent, light industry, electrical industry pencil brush, industrial battery electrode and catalyst in chemical fertilizer industry, etc.. Flake graphite is further processed and can be used to produce graphite milk. It is used as lubricant, release agent, drawing agent and conductive paint. Expandable graphite can also be used for flexible graphite products, such as flexible graphite seals and flexible graphite composite products.
- Q:Why does an electromagnetic point timer not prick a needle and use toner paper?
- With the needle point than the powder paper friction, many experimental results of!
- 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:Whether the lubricating oil toner is coupled with the conductor?
- You don't want to lubricate the rheostat. The metal piece in it is in direct contact, so even the lubricating insulator won't make any difference (as long as you don't rub it too much).
- Q:Crystal graphite of graphite powder
- The crystal structure of highly structured pyrolytic graphite, La above 2000Nm, from low temperature to high temperature, the thermal conductivity changes with the temperature is bell shaped, see Figure 1, figure 2.
- Q:How much is one graphite used as electrode?
- Product Name: graphite electrode, graphite crucible, graphite plate, graphite tile, graphite powderProduct price: 7000 yuan / tonCompany location: Hebei, Handan
