Amorphous Graphite Powder KL-85 & by customer's requirements

Amorphous Graphite Powder KL-85

We offer amorphous graphite with a carbon content from 70-89% and sizes from minus 200 mesh up to 5mm pellets

IEA International Trading Qingdao Ltd. maintains a detailed data base of all different deposits and nearly all 130 Chinese graphite refineries. This enables us to manage the production of graphite meeting even exceptional customer requirements, e.g. concerning specifications of bulk density or ash composition.

We know the strong points of each graphite mine or refinery. Thus we are able to offer highest quality grades of graphite. Our suppliers are certified according to DIN ISO and monitored by a continuing quality control.

Q:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?
The solution of potassium hydroxide at a density of 1.25~1.27 (15 DEG C) is used at temperatures below -15. For the purpose of taking into account the low temperature performance and the charge holding capacity, the sealed nickel cadmium battery adopts an aqueous solution of potassium hydroxide with a density of 1.40 (15 DEG C). In order to increase the capacity and cycle life of battery, usually adding lithium hydroxide amount in the electrolyte (per litre of electrolyte and 15~20g).
Q:How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
Method three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectivelyIf bubbles are produced and green light is generated, the solution is iron powder (chemical equation Fe+2HCl = FeCl2+H2)The reaction is more intense, there are more bubbles, the color of the solution does not change, it is aluminum (chemical equation 2Al+6HCl = 2AlCl3+3H2)No obvious phenomenon is graphite powder (not reaction)(2) if the difference between the bubble phenomenon is not obvious, then two kinds of powder with magnetCan be the magnet is not attracted by the permanent magnet is iron powder; powder(high school can also use NaOH solution to identify iron aluminum, aluminum reacts to dissolve hydrogen, iron does not respond)
Q:Is battery capacitor powder dangerous?
Graphite is very soft, creamy feel. It has excellent electrical conductivity. Color steel gray or gray, with metallic luster, with lubrication, easy dyes, chemical stability, heat conductivity, good heat resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, due to its small crystal plasticity, good adhesion, so it does not belong to the dangerous goods!
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:Does graphite allow lubrication of rusted doors?
Into the rusty iron graphite powder can play the role of lubrication, graphite powder can open the door locks rust.
Q:Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?
Dust produced in the process of production of some factories and mines, especially the dust produced in the processing of some organic matters, will explode and burn under certain conditions.(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction.Such as effective ventilation and biological film, dust suppression technology, integrated dust suppression technology, dust removal measures, smoking and fire operations are prohibited. A pressure relief valve or other device is arranged in the outer shell of the equipment, and an explosion containment system is adopted. For factories with dust explosion hazards, the design must be strictly carried out according to the technical grade of explosion protection, and ventilation and dust removal systems shall be installed separately. Often wet cleaning workshop floor and equipment, to prevent dust flying and gathering. Ensure that the system has a good airtight, if necessary, in airtight containers or pipes in the flammable dust filled with nitrogen, carbon dioxide and other gases, in order to reduce the content of oxygen, dust suppression explosion.
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:Graphite powder what is the difference?
Graphite is a isomer of carbon, chemical symbol C, non-metallic, non-toxic, relatively smooth, can be rubbed on the key, harmless to the baby.
Q:Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?
The other is to install an electrostatic eliminator when the material falls into the vibrating screen. When the material is dropped, the powder static electricity is removed and the mass will not be assembled again.
Q:Can graphite be made directly from graphite powder? How about the effect?
Let the graphite powder stick into shape. 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.
