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:Thermal conductivity and density of graphite powder
For the same type of graphite, the thermal conductivity increases with increasing density, and Figure 11 shows the relation between the density of HDFG and the density of the same graphite.The heat treatment temperature of polycrystalline graphite is mostly made by roasting the semifinished material by high temperature heat treatment. The higher the heat treatment temperature is, the more perfect the crystallite growth is, the La increases, and the thermal conductivity also increases. With calcined petroleum coke and coal tar pitch, roasting sticks made of extrusion, after different heat treatment (HTT), the value of La are shown in Table 4. The axial thermal conductivity will change with temperature is shown in figure 12. The reciprocal of thermal conductivity 1/ lambda is called thermal resistance. At different temperatures, the relationship between the axial thermal resistance of graphite is shown in Figure 13 and l/La / 1/.
Q:What is graphite powder?
Graphite is soft, black and gray; greasy feeling, can piece of paper pollution. 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. Under normal temperature and chemical properties of graphite is relatively stable, insoluble in water, dilute acid and dilute alkali and organic solvent; different high temperature reaction with oxygen, carbon dioxide or carbon monoxide; only in halogen fluorine can react directly with elemental carbon; under heating, the graphite powder is easy to be oxidized under high temperature, acid; but with many metal reaction, formation of metal carbides, can smelt metal at high temperature.
Q:Why does an electromagnetic point timer not prick a needle and use toner paper?
It's a combination of graphite powder and current to mark the surface of the tape. You can imagine it as an inkjet printer
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 graphite powder made of graphite products, high hardness?! Wear-resisting! Good moisture! It can be made into graphite products at 100-200 degrees high temperature
100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.
Q:How to measure the iron content in graphite powder?
Take a certain amount of samples, adding dilute hydrochloric acid, excessive filtering and drying. The quality of the filter residue. By weighing the quality of the sample quality is the quality of minus slag containing iron. With this value divided by the sample quality, the mass fraction of iron.
Q:How to deal with graphite powder? Anyone recycle it?
Graphite powder is an important industrial raw material, there is a recovery, but the graphite powder you said should be a waste in the production of surplus, quality is better than before, but the graphite powder prices, some specialized recycling of the graphite powder, graphite powder is not a professional manufacturer of recycling, is the original mineral for graphite the raw material, want to help to you, hope to adopt, thank you.
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:Does the pencil core go into the baby's face to keep the skin tight?
If it's obvious, you need to go to the hospital early, otherwise the macula can last for a long time (a few years, or even ten years). This I have experienced (hand stabbed too) for at least more than 10 years, black.
Q:What if the key is inserted in the hole and can not be drawn out?
Don't use the strength to Jin qiao. You can also pour cold water into the hole. It's very useful
