Q:Crystal graphite of graphite powder: At room temperature, lambda A is about 200 times larger than lambda C. As the temperature increases, this ratio decreases, but remains large. Therefore, the thermal conductivity of polycrystalline graphite composed of microcrystalline is controlled by the thermal conductivity of microcrystalline layer lambda a, and lambda C can hardly be considered. The lambda a of natural flake graphite is between 280 and 500W/ (m * K) at room temperature. The ratio of lambda a/ lambda C is between 3~5, so the perfection of crystal is far better than that of high directional pyrolytic graphite.

Q:Does graphite allow lubrication of rusted doors?: Sure。 When we were young, the teacher reminded us that we could use the pencil core to scrape the end and put it into the keyhole to lubricate it.

Q:What if the key is inserted in the hole and can not be drawn out?: The end of the pencil is made of graphite, and the graphite powder can be used as lubricant for the machine running under high temperature, and the pencil core can be made. Add some pencil powder to the keyhole. Try to lubricate the inside of the keyhole. Try it!

Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.: In industrial enterprises, when the dust concentration in the dust producing area is within the scope of explosion, dust explosions can occur if contact with an open flame is waiting for the fire source

Q:The principle of a graphite missile: Graphite conducts graphite on the wire to short-circuit the circuit

Q:Is the graphite electrode broken like graphite, fossil oil, coke and graphite powder?: Graphite fossil oil coke is the best smelting carburizing agent. In the steel-making industry, to produce good steel, there must be good raw materials, including good carburizing agent, and the graphitization of petroleum coke is the best carburizing agent.

Q:What is graphite powder?: 1) high temperature resistance: Graphite melting point of 3850 + 50 degrees, boiling point is 4250 degrees, even after the ultra-high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is very small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade.2) conduction and thermal conductivity: the conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Heat conductivity exceeds steel, iron, lead and other metal materials. The coefficient of thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, the graphite becomes hot.3) lubricity: the lubricity of graphite depends on the size of graphite scales. The larger the scale, the smaller the coefficient of friction and the better the lubricity.4) chemical stability: graphite has good chemical stability at room temperature, and can resist acid, alkali and organic solvent corrosion.5) plasticity: the toughness of graphite is good, but it can be a very thin slice.6) thermal shock resistance: when graphite is used at normal temperature, it can withstand the drastic change of temperature without damaging. When the temperature changes suddenly, the volume of graphite changes little and no cracks occur.

Q:What effect does graphite powder and graphite gas have on people? Also, I smell graphite gas as if I can't breathe. What's the harm to people?: This is determined by the quality of the graphite powder. Graphite workers in our factory are equipped with masks to prevent dust. (formerly, Shandong, South villa, graphite mine) more than 5000 state-owned enterprises, workers have worked for 20-40 years, and has yet to find too much harm to the body. Pay attention to dust protection measures.

Q:Influence and protection of graphite dust on electrical equipment in workshop: Graphite powder is very easy to cause static electricity and short circuit, especially for the weak point, the graphite powder must be filtered out, or the electric distribution box is placed separately.

Q:Can you tin to latex paint: Can not brush metal thermal expansion and contraction principle is very strong, or how long it will fall off, really want to brush with a small nail unless many small eyes in atoms in the metal, and then dust coat paint brush
