Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Special graphite for electric spark processing

Electric spark processing is a new type of processing process in the mechanical manufacturing industry. Electric spark processing can process many metals with large hardness and can be processed. Copper materials can also use graphite materials. Graphite materials used for electrical electrodes used for electrical sparks must have the following conditions:(1) The structure is dense and uniform in tissue, and there should be no coarse particles and large pores;(2) There is a high mechanical strength and good processing performance. It can process complex shapes or sharp corners and thin slices;(3) Graphite tool electrodes, there are certain losses during the processing of electricity, this loss should be as low as possible;(4) The discharge characteristics are stable and the processing speed is fast. Therefore, graphite machining is generally used with graphite structure graphite or exquisite particle structure graphite. It is best to have the same sex in physical properties. Therefore

Industrialization process of battery specific Graphene lithium battery

1. Cost issuesThe cost of using Graphene as a conductive agent is much higher than that of ordinary carbon black. The cost of lithium battery is the key control factor. Without reducing the cost of raw materials, even if the electrical performance of Graphene is no better, battery manufacturers can not afford to consume hundreds of thousands of dollars per ton.2. Process issuesThe technical problems caused by the sheet structure of Graphene for batteries are mainly the preparation of electrode paste. The electrode paste requires good fluidity, dispersibility and proper viscosity. The dispersion of Graphene sheets in the electrode paste is a problem, especially the electrode paste cannot be dispersed by adding dispersants. Graphene has a large surface area, which has a great impact on the stability of the slurry settlement, cannot guarantee the consistency of each batch, and affects the battery performance.3. Other factorsThe lamellar structure of Graphene for batteries inhibits the di

What is the role of scales when galgling?

The application of scales graphite is widely used in industries. Mulchogenic sand is one of the applications of them. Cover sand refers to the sand or core sand with a solid resin film on the surface of the sand grain. In the middle, scales need to be used. Today, I will explain what the scales have the functions when gog graphic is covered with membrane sand:The scaled graphite is used as a lubricant in the lubricant in the sandy sand. The littering of the luster sand can play a lubrication and high temperature resistant role in the sandwich sand. For the requirements of scales with scales in gifsta, it is required to be lubricated as a lubricant and high melting point, and the littering of the lubrication is a natural scale graphite with good lubrication. Carbon content. The melting point of the scale graphite itself is very high. After the production process processing, the high temperature resistance of scales graphite with scales with scales will be higher, and the lubrication ef

What is graphite

Graphite is a kind of homogenous alien body for carbon. It is gray -black, opaque solid, stable chemical properties, corrosion resistance, and it is not easy to react with drugs such as acid and alkali. Natural graphite comes from graphite ore. It can also be used as a raw material for oil coke, asphalt coke, etc., and made a series of processes to make a human -made graphite. Graphite is burned in oxygen to generate carbon dioxide, which can be oxidized by strong oxidant such as concentric acid and potassium permanganate. It can be used as an anti -wear agent and lubricant. High -purity graphite is used as a neutron decelerator in the atomic reactor. It can also be used to manufacture crickets, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, and arc

Purification method of graphite

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has lower costs. This is a major advantage of the flotation method for purifying graphite. However, when using the flotation method to purify graphite, it can only achieve a limited improvement in the grade of graphite. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomers, but also is not conducive to protecting the large flakes of graphite. Therefore, using flotation to further improve the graphite grade is not economical or scientific. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） Chlorination roasting methodThe low roasting temperature and low chlorine consumption of the chlorination roasting method greatly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after tr
