Precautions during the storage process of carbon material raw materials

(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces

The key role of graphite in battery technology

The special function of the wiper with graphite powder

Wiper dedicated graphite powder is specially used to produce high -quality car wiper. The wiper is composed of wiper and wiper motors. The components of high -quality wiper and motor should be added with graphite powder. The wiper with graphite powder has excellent performance such as high temperature resistance, lubrication, and corrosion resistance.The following is a special function of the wiper with graphite powder:The car wiper is installed on the front window of the car, often exposed to high temperature and low temperature, and exposed to wind and sunlight. When the wiper works, it is basically in rainy days. When the wiper works, it should rub the glass of the car's front window, take the rainwater, etc., and clean the window. The wiper will be damaged if used for a long time. When producing a good quality scraper, graphite powder is usually added. The parts in the wiper motor are also made of graphite powder. Graphite used for wiper mainly plays a role in lubricating and redu

The use of scales graphite and colloid graphite

Scales graphite is a very widely used non -metallic powder product, with good thermal conductivity, conductivity and lubrication effect; colloid graphite is a graphite product that uses natural scales graphite as the main raw material. There are certain differences in use. The following editor will introduce the purpose of scales graphite and colloid graphite:The scales graphite has a strong conductive capacity. It can replace the metal as a conductive material. The scale graphite can also be directly used as a carbon conductive filler or a composite conductive filler for conductive coating. The quality of scales graphite powder has a lot to do with its carbon content. Natural scales graphite collected from natural mines often contain a lot of impurities. It needs to be purified to get graphite powder with high carbon content because of high purity scales. The use of graphite is more widely used, providing an effective solution for the miniaturization and high integration of electroni

Method of making low -density puffed graphite blocks with flexible graphite

In recent years, various types of low -density carbon graphite materials have been actively researched, including carbon (graphite) foam made of asphalt or polymer resin, as well as using high repetition pulse laser to abolish carbon materials The carbon nano foam formed. Granny Gygm is also a low -density carbon graphite material. Due to the simple preparation process and low production cost, it is convenient for large -scale industrialized production. In recent years, the research on expandable graphite has continued to deepen. The following editor of Jinhui Graphite Company introduced the method of soaking flexible graphite in the concentrated acid into a low -density puffed graphite block:The insect shape and weak macro structure of puffed graphite restrict their application. If it can be made into a stable -swollen graphite block, it will be conducive to puffed graphite to play its role as adsorption, heat insulation, heat conduction and other functional materials. The flame reta

Graphite physicss

The chemical properties of single -mass carbon at room temperature are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; burning with oxygen at different high temperatures to generate carbon dioxide or carbon dioxide; Below, single -quality carbon is more likely to be oxidized by acid; at high temperature, carbon can also react with many metals to generate metal carbides. Carbon is restored and can smell metal at high temperature.Graphite is soft, black and gray; it is greasy and can contaminate paper. The hardness is 1-2, and the hardness can be increased to 3 to 5 along the vertical direction. The proportion is 1.9 ～ 2.3. The surface area is concentrated at 1-20m2/g. Under the isolation of oxygen conditions, its melting point is above 3000 ° C. It is one of the most temperature-resistant minerals. It can conduct electricity and heat conduction.There is no pure graphite in nature, which often contains impurities such as SIO2, Al2O3, Feo, CAO, P2O
