Natural Flake Graphite (32-500mesh)

1) Specifications: The particle size ranges form 32-500mesh
2) Carbon content ranges from 80 to 99%.
3) Advantages: Perfect crystallization, thin flake, good flexibility, excellent chemical and physical properties, superior conductivity, self-lubricity and resistance to temperature, corrosion and hot shock, and much more.
4) Usage: Crystalline flake graphite is widely used as an essential nonmetalic mineral in almost all industries. It can be used as high-quality refractory material or coatings in metallurgical industry, black lead in light industry, carbon brush in electronics industry, electrode in battery industry and catalyst in chemical fertilizer industry, to name just a few. After being deep processed, crystalline flake graphite can be used to produce TV tube coatings, graphite friction reducing additives and many other high-tech products.

Q:How does graphite powder look good or bad?
The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
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?
Just add some water and rub it over and over again with wooden sticks or bamboo strips. The effect will be better with water. Do not use hard objects such as glass bars, or your glass becomes a flower.
Q:Is the graphite powder poisonous?
There are three kinds of substances that fly out of the black spot from the carbon factory:1. Bituminous dust.2. A relatively fine particle of calcined coke (petroleum coke after calcination).3. A fine particle of calcined and graphitized Shi Mofen (calcined coke and bituminous mixture).Both poisonous.
Q:What effect does graphite powder and graphite gas have on people? Also, I smell graphite gas as if I can't breathe. What's the harm to people?
If it is a long-term work in the environment first, graphite dust masks, the more than 2 eat bananas, like blood. Case said harmful, you can not see any problems with graphite processing. In short, the dust class should pay attention to, and avoid direct inhalation
Q:How much is the price of graphite powder for a ton?
Qingdao Chenyang graphite is China's Graphite brand-name products, strong technical force, perfect measuring and testing, quality assurance system.
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:What is the industry standard of graphite powder coating for casting?
The two is fine, the finer the better, generally with the "eye" as a unit, that is, sieve stone toner used in the screen, square inch area included in the number of holes, the larger the number the better.
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:Refractive index and absorbance of graphite powder
Color changes indicate that the absorption of light inside the material has changed, it can not be compared by the size of the relative content of absorbance. By absorbance, the content must be of the same substance and comparable at the same wavelength.
Q:What binder does the graphite powder form with?
Image, graphite powder, like flour, in order to make bar shaped, such as face and water, you need to add something. Because of the low activity of graphite powder, a kind of binder is needed. Let the graphite powder stick into shape.
