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:The difference between silicone and silicone?: The biggest danger in silicone applications is that they lose stickiness when the chips heat up to a certain point. Although the silica gel will not lose viscosity at higher temperatures, it will take a long time to use and the heat on the heat sink can not be removed in time. The possibility of silica gel melting is considerable. I have encountered two occasions that only the heat sink and no fan card in the use of heat sink fall.

Q:Refractive index and absorbance of graphite powder: When the matter to be measured is different, or the wavelength chosen is different, the molar absorption coefficient will be different, so that it can not meet the quantitative relationship of Bill's law.

Q:What are the hazards of inhalation of graphite dust?: It must be harmful to human beings! Look at the dictionary of carbon black dust lung disease Description: black carbon pneumoconiosis: long-term inhalation of carbon black dust caused by pneumoconiosis. Carbon black is mainly the quality of easy flying carbon. Although the production has been closed and automated, the phenomenon of dust flying still exists. Therefore, workers who produce and use carbon black may have black carbon pneumoconiosis, the shortest length of onset is 15 years, the longest can be more than 25 years, the clinical symptoms are mild, and the progress is slow, and generally does not affect the ability to work.

Q:The principle of a graphite missile: The graphite missile contains carbon fibers and is highly conductive. After the explosion of carbon fiber floats attached to the high-voltage lines immediately cause transformer short circuit burned, to destroy the enemy's power to.

Q:Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.: A cylinder is inserted in the pipe, and the cross section of the pipe is slightly smaller than the inner diameter of the sample tube. The lower cylinder is fixed on the base of the instrument, and the upper cylinder can move up and down in the tube as a prop to pressurize the sample. The sample is located in the insulating casing on the cylinder between the positive and negative pole and galvanometer millivoltmeter are respectively connected to the drum two cylinder, rotary measuring height, driven by the leading screw rod lifting rod to balance, balance level, sample by 3.92MPa pressure, then switch on the current, the current adjustment into the sample to 300mA, then open the switch millivoltmeter,

Q:Why does the temperature rise when the graphite powder is turned on?: The presence of resistance, melting point at 3850 + 50 degrees C, graphite powder is a very sensitive chemical substances, in different circumstances, his resistivity will change, that is, his resistance value will change

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: 100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.

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:Is battery capacitor powder dangerous?: Will pour into the dry drying workshop, drying after bagging, namely ordinary graphite powder, the carbon content of the finished product is an average of 90%. Use to make pencil cores, graphite electrodes for batteries, lubricant features for cable cars, a dark gray, metallic, opaque, flaky solid.
