graphite powder manufacturer,with graphite mine. 
-180,-280,-285,+895,-195...... 
30000Mt per year

graphite powder

Particle size: 32mesh to 5000mesh,

carbon content: 80-99.99%.

 

Property:

Scale is thin,flexible and crystallized completely with excellent physical and chemical properties such as good temperature resistance,self-lubrication,conductibility,heat resistance,shake resistance,and erosion resistance.

 

Use:

Widely applied to high quality fire resistance material and coating of metallurgy industry,hot working material stabilizer of military industry,lead of light industry,carbon brush of electrical industry,electrode of battery industry,and catalyzer and additive of fertilizer industry.After further process,scale graphite can be made into the following high-tech products such as graphite colloidal graphite,graphite compacting material and composite material,graphite products,and graphite anti-friction additive,which are becoming important nonmetal mineral materials in every industry.

Q:Whether the lubricating oil toner is coupled with the conductor?
You don't want to lubricate the rheostat. The metal piece in it is in direct contact, so even the lubricating insulator won't make any difference (as long as you don't rub it too much).
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:Why does an electromagnetic point timer not prick a needle and use toner paper?
With the needle point than the powder paper friction, many experimental results of!
Q:It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?
Graphite is chemically stable (inert), to eliminate it used two methods: one is under the condition of high temperature combustion has sufficient oxygen to remove (heating in a muffle furnace effects are poor), certainly not with the glass bottle; two with hot concentrated sulfuric acid, concentrated nitric acid oxidation to remove heat, if not heating your glass bottle this method, also difficult.
Q:Distinguish iron powder and graphite powder by chemical method
This problem is very simple, the use of chemical methods to distinguish: there are many ways to give me introduce you to some here, one plus HCl for Fe+HCl=FeCl2+H2, C and HCl reaction, 2: they were put into CuSO4 solution, can replace the red metal iron, whereas C
Q:Know how the colloidal graphite powder comes in
Colloidal graphite is a kind of nano material of graphite. The particle size between 1 and 100 nm is called colloidal graphite.Colloidal graphite prices are mainly based on the grain size and carbon content to develop, according to the amount of carbon graphite into high purity, high and medium carbon and low carbon four files, each grade of the difference between the price of a large, but since processed into colloidal graphite, then the carbon content of high carbon should at least be above, if there is no way know the amount of carbon it can only roughly estimate the price of 4-6 million / ton, if it is pure graphite (carbon 99.9%-99.99% above) the price is at least 100 thousand / ton
Q:Why does the temperature rise when the graphite powder is turned on?
But one thing will not change. Graphite powder is one of the best nonmetallic conductive materials. As long as the graphite powder is kept inside the insulating object, it will electrify as a thin line
Q:Main ingredients of graphite powder?
These impurities often appear in quartz, pyrite, carbonate and other minerals.
Q:Graphite and graphite in the end is not a matter I would like to know the graphite and graphite
Graphite gum APS two, colloidal or semi - colloidal graphite. (a) colloidal graphite, graphite powder from natural or artificial graphite fine powder in water or other media (e.g., alcohol, mineral oil) colloidal suspensions in the form, and can add a few other products (e.g., tannic acid or ammonia) to be stable. Colloidal graphite is usually semi liquid and is used primarily for lubricating products or for its high electrical conductivity. (two) a semi colloidal graphite (i.e., a colloidal suspension of graphite in water or other medium). Semi crystalline graphite can be used to prepare graphite lubricants or to form graphitized surfaces. This class contains only colloidal or semi colloidal suspensions of graphite with graphite as base material in any medium.
Q:Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it
If you want to hit the plane down, EMP is more practical! Besides, it is also expensive than with stinger!
