Q: What are the hazards of inhalation of graphite dust?: The main pathological change was two lung was black, the whole lung has isolated or clusters of small black nodules around the bronchioles and small blood vessels, irregular nodules; around focal emphysema, pleural thickening and adhesion. X - ray was mainly manifested in increased lung markings, with fine mesh fabric and fine nodular shadows, coarse mesh progression increased, often associated with emphysema, China has listed as the occupation scope of carbon black pneumoconiosis disease.

Q: What are the specifications of the graphite powder used for conduction?: There are many kinds of specifications. There are 1 grams, 2 grams, 3 grams, which kind do you need?

Q: For thermal grease skills, the more detailed the better: If the fins and the metal cover of the CPU are as smooth as mirrors, they will be 100 percent fully exposed to the best thermal conductivity.

Q: What does composite graphite mean?: Flexible graphite is prepared into graphite powder as a kind of simple, while the composite graphite is graphite powder with one or more other medium mixed products, their preparation materials are different, the application is different, the above information is a reference to Qingdao Huatai graphite.

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: 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.

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 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: Why does the temperature rise when the graphite powder is turned on?: What is the value of resistance, and this value is not an accurate number, because the graphite powder thickness is not the same, used in different materials and environment, graphite powder, resistance value will be different.

Q: What kinds of graphite powder has it? What's the function?: The graphite powder can be divided into colloidal graphite powder and graphite powder, both of which are graphite products, and the colloidal graphite powder is colloidal
