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:What is the use of flake graphite in making flake graphite powder?
Better for corrosion protection coatings, fire retardant coatings and conductive coatings.
Q:What binder does the graphite powder form with?
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.
Q:Is the graphite powder produced with sulphuric acid?
Not only by crushing crusher can achieve, such as high purity stone toner, expanded graphite by sulfuric acid and other chemical methods for purification, preparation and so on
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:How to identify iron powder and graphite powder in a simple way?
Can also take the first touch, using magnets to attract or drop method with acid identification of three substances. [a] analytical method (first touch after magnet): touch the two kinds of powder by hand, are oily powder graphite powder, and then take the other two kinds of powder with a magnet, the magnet can be as for iron, can not be sucked up into powder;
Q:What is special graphite powder used in graphene?
Graphene special graphite powder is specially used for the development of graphene, graphene graphene from graphite powder is special in stripping out, universities and research institutions of graphene special graphite powder, graphite powder, graphene special quality of Qingdao Huatai provide very good, have a good reputation among colleges and universities, scientific research institutions in such help, hope to adopt L.
Q:The difference between silicone and silicone?
Silica gel and grease are helpful to system cooling material, the difference is that the silica gel with good thermal performance and insulation, and will not lose its stickiness pale yellow translucent glue at higher temperatures, mainly used in the surface of the heat radiating sheet sticking device; and the grease is not sticky, is a liquid emulsion or cream like, its role is to fill the gap between the chip and the heat sink, improve the efficiency of heat conduction.
Q:Know how the colloidal graphite powder comes in
Smaller graphite particles are uniformly dispersed in water, oil, and other organic solvents, forming a black, sticky suspension. Also called colloidal graphite or graphite milk.Colloidal graphite was first obtained in nineteenth Century by Acheson. The raw material is natural graphite or artificial graphite.
Q:Can graphite be made directly from graphite powder? How about the effect?
Because of the low activity of graphite powder, a kind of binder is needed.
Q:What is the simple test method for graphite powder used in casting?
Mainly depends on its carbon content, hand stick a little bit on the white paper uniform, if there is a clear scratch is graphite powder
