Specifications

Flake Graphite is divided into three grades:High Purified Graphite,High Carbon Graphite and Medium Carbon Graphite

Grade:

Flake Graphite is divided into three grades: High Purified Graphite, High Carbon Graphite, Medium Carbon Graphite.

Specification: Particle size from 500µm to 1mm, carbon content from 80 to 99.99%.

Property: 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.

Usage: Being widely used as an essential industrial mineral material in almost all industries, being used as high-quality refractory material or coatings in metallurgical industry, stabilizer in military industry, lead core 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, flake graphite can be used to produce TV tube coatings, graphite sealing material and composite material, graphite carbon products, graphite friction reducing additives and many other high-tech products.

Q:What is the ratio of the coated sand to the graphite powder? How to improve the refractoriness of precoated sand: In addition to improve the refractoriness with graphite, can also add red. It also plays a role in increasing refractoriness and reducing gas output.

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:What's the conductivity of graphite powder, silver powder?: The resistivity of silver is about 1.6*10-8.M at room temperature

Q:Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?: Ultrafine toner is a thermal conductive function, because ultrafine toner is processed from natural graphite, which inherits the characteristics of natural graphite conduction and heat conduction.

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?: Graphite powder itself is harmless, and even eat nothing, you smell the so-called graphite powder can only be said to be in (high temperature) such as copper and aluminum smelting gas produced by graphite powder, graphite powder for sulfur, after high temperature will have a S taste great, as far as possible to avoid a long time.

Q:For thermal grease skills, the more detailed the better: But this is not possible, the metal lid heat sink and CPU looks smooth, but with a magnifying glass, you can see many holes in metal surface concave stripes and irregular tunnel, lead contact surface with many gaps, these gaps are impeding heat dissipation, thermal grease is liquid, can fill the gaps. Improved radiating surface contact, the heat dissipating effect than when there is no good thermal grease. But if the thermal grease is too thick, it will become a film on the contact surface of the middle, but hindered the direct contact of metal, worse than not coated with thermal grease.

Q:Is the graphite electrode broken like graphite, fossil oil, coke and graphite powder?: Graphite fossil oil coke is the best smelting carburizing agent. In the steel-making industry, to produce good steel, there must be good raw materials, including good carburizing agent, and the graphitization of petroleum coke is the best carburizing agent.

Q:What kinds of graphite powder has it? What's the function?: The graphite powder can be divided into colloidal graphite powder and graphite powder, both of which are graphite products, and the colloidal graphite powder is colloidal

Q:How much is the price of graphite powder for a ton?: Battery with graphite powder to Qingdao Chenyang graphite Co., the quality is reliable, trustworthy

Q:How does graphite powder solidify into a lump? What bond is best used?After solidification can be more than 1000 degrees high temperature does not change: The only way to do this is by using physical methods, high temperature and high pressure, to agglomerate the graphite powder from the molecular level. Now, by simulating the high temperature and pressure of the earth's crust, graphite can be turned into diamond (that is, diamonds)
