Q:Are graphite and carbon black the same?: Not the same, graphite is extracted from the mine, the black soot is ""

Q:Is graphite powder conductive?: The bottom current may be the internal resistance of the battery is too large, in addition to graphite reasons, the contact state of battery cathode and graphite copper check, graphite powder, no contact measurement, the conductivity of no experience, resistance measurement of graphite column can be compared (with the current large and small current comparison test),

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:Use of carburizing agents: Recarburizer steelmaking using recarburizer (People's Republic of China ferrous metallurgy industry standards, YB/T 192-2001 steel with increased carbon agent) and cast iron using recarburizer, and add some other materials are useful to the carburant, such as brake pads additive for friction materials. The carburizing agent belongs to the raw material of additional steelmaking and ironmaking. High quality carburizing agent is an indispensable additive for the production of high quality steel.

Q:Why does an electromagnetic point timer not prick a needle and use toner paper?: Needles can increase friction! Will increase the error!

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: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:How does graphite powder look good or bad?: Graphite powder is a kind of negative electrode material for batteries.The process of graphite powder, will after the bursting of the raw ore by car to crush the rock breaking machine, and ball mill by flotation, the flotation of graphite ball mill grinding wet material sending selected, wet material will be selected to bagging dry dry machine, shower shower has become dry, dry material is graphite products. 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%.The utility model relates to a pencil core, a graphite electrode for a battery, and a lubricant for a cable carA dark gray, metallic opaque opaque flaky solid. Graphite is very soft, creamy feel. It has excellent electrical conductivity

Q:How can graphite paper be made? Can graphite powder be solidified without brittleness?: Single layer graphite paper is all graphite products, excluding other materials

Q:How can the clinker graphite powder be dissolved in water?: To achieve this purpose many methods; the titanate coupling agent and silane coupling agent is used in simple water dispersion system of the surface modification, hydrophilic group will make Shi Mofen (film) dispersed in water while stirring under shear stress.
