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.

Heat conductive graphite characteristics

Features: The surface can be combined with other materials such as metal, plastic, non -drying, etc. to meet more design functions and needs.Low thermal resistance: The heat resistance is 40%lower than that of aluminum, 20%lower than copper.Light weight: weight is 25%lighter than aluminum, 75%lighter than copper.High -conductive coefficient: Graphite radiator can be smoothly attached to any plane and curved surface, and can cut any form of cutting according to the needs of customers.The artificial graphite film is widely used in important emerging industries such as new energy and energy -saving transformation with its high thermal heating high reliability, lightness, easy processing, and environmental protection.

What are the reasons for the low initial efficiency of lithium carbide graphite negative electrodes

1. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas

Graphite hydrillinosteric acid method

Hydrofluoric acid is a strong acid, which can react almost with any impurities in the graphite, and graphite has good acid resistance. In particular, it can resist hydrofluoric acid. It determines that graphite can be purified with hydrofluoric acid. The main process of hydrofluoric acid method is mixed with graphite and hydrofluoric acid. The hydrofluoric acid and impurities response generate soluble substances or volatiles for a period of time. After washing and r

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

Can expand graphite development

Graphite crystals have a hexagonal layer -shaped structure composed of carbon elements. The carbon atoms on the layer of flat plane are combined with powerful covalent bonds. Therefore, under appropriate conditions, a variety of chemicals such as acid, alkaline metals, and salt can be inserted into the graphite layer, and a new chemical phase -Graphite Intercities on compounds (referred to GIC). When this intervertebral compound is heated to an appropriate temperature, it can quickly decompose instantly, generating a large amount of gas, so that the graphite is expanded into a new substance of worm -shaped, that is, the expansion of the intervertebral compound of the expansion. graphite.The expansion graphite was first discovered by the German SChaufautl. In 1841, Schaufautl soaked natural graphite in a mixture of thick HNO3 and thick H2SO4. In 1963, he first applied for expanding graphite manufacturing technology patents and industrialized production in 1968.The above is some of the
