Do You know How you can Make Graphite By Graphite Producer?

Maybe you have heard of Graphite Crucible，which is made of graphite. That's for certain. But just how much do you understand about the machining of graphite?

Let us speak about the graphite purification method. To become specific, graphite purification，can be divided into two techniques which may be included chemical purification and physical purification.

Now, let’s say some thing about chemical purification, which belongs to Graphite Machining. Normally speaking, chemical purification can use the nature from the graphite’s acid resistance, alkali resistance and anti-corrosion. We are able to use acid and alkali to accomplish treatment for graphite concentrated ore. As a result, we are able to make impurities dissolve. Following that, we can wash all of the impurities away. In this way, we can enhance concentrate ore’s grade. By utilizing the strategy of chemical purification, we can get grade 99% of higher carbon graphite. Electric Discharge Machining may also be used.

Even so, there are lots of techniques for chemical purification, the strategy which we most extensively use can be sodium hydroxide high-temperature melting method. Graphite Producer can give us more details.

As for the fundamental principle of chemical purification, when it is below the condition of higher temperature which can be more than five hundred degrees, the graphite’s impurities (which mainly belong to the silicate minerals) can react with caustic soda which can be referred to as NaOH. Within this way, we can make them generate water soluble reactants. At the same time, we are able to use water to leach reaction supplies. Because of this, we are able to eliminate part of the impurities. As for yet another a part of impurities, including iron oxides, we can use alkali fusion and HCl to finish neutralization. Within this way, we can make them to generate ferric chloride which is soluble to water. If we use water to wash such sort of impurities, they're able to all be removed.

The equipments employing Alkali fusion can be mostly divided into anchored mixer, melting furnace, spiral mixer, V type washing tank and so on. By the way, the recovery price might be eighty five to ninety percent. And we ought to finish investment with a single hundred and fifty thousand to two hundred thousand yuan. As all of us know, though the approach is a lot more sophisticated, but there are also some disadvantages. As an example, we have to consume a large volume of water, the loss of graphite is a lot a lot more, the productivity is low, large volume of alkali consumption and emissions of waste pollution to the environment.
