How to distinguish the quality of high -purity graphite board?

In fact, many production manufacturers of high -purity graphite board are unclear how to differentiate the quality of high -purity graphite board. Some manufacturers say that they are used as fine particles, and some manufacturers say they are the secret recipes of their ancestors. In fact, the only key to judge the quality of high -purity graphite board is to query its density.In the electroplating and electrolytic industry, many manufacturers only favor the conductivity equivalent of high -purity graphite boards and ignore its density. Assuming that the density of high -purity graphite chips is small, it is very easy to form air holes on the surface layer. It is very easy to enter the lithium battery electrolyte of lithium battery, and then form a graphite pole. Period of use. It is convenient to use in the wear -resistant steel industry and can also be used to high -density fiber board industry.

Several methods for preparing nano graphite powder using natural graphite

(1) Detonation cracking methodThe detonation cracking method utilizes the properties of graphite that can accommodate foreign negative ion layers to form expandable graphite or lower order GICs, where the ion layer contained is called the insertion layer. In expandable graphite or low order GICs, the insertion layers are regularly arranged in graphite layers. During detonation, the insertion layer rapidly decomposes and releases a large amount of gas, impacting the graphite layers and pushing adjacent graphite layers apart to prepare nano graphite thin sheets. During the detonation process, * * plays two roles simultaneously: firstly, it releases a large amount of heat during the explosion, causing the decomposition of expandable graphite or lower order GICs; The other is to use the shock wave generated during detonation to crush the graphite sheet, achieving the effect of refining the graphite, thereby preparing flake graphite with smaller diameter and very thin thickness.At present,

Graphite, the Power of Tranquility

Graphite, seemingly ordinary, contains the power of tranquility. It is not ostentatious or ostentatious, but silently supports the backbone of modern industry. Whether it is steel smelting or new energy development, graphite provides solid support for industrial development with its stable performance and outstanding characteristics.The power of graphite is also reflected in its contribution to the environment. As an environmentally friendly material, graphite plays an important role in replacing traditional high polluting materials. Its use not only reduces energy consumption and waste emissions, but also promotes the development of green industries.The power of graphite is also a spiritual force. It represents resilience and perseverance, reminding us to remain calm and firm in the face of difficulties and challenges. Let us work together to explore the greater potential of graphite and contribute more to the progress and development of humanity.

Unique chemical properties of industrial graphite products

Graphite is an important mineral resource in the 21st century, and China ranks first in the world in terms of graphite ore reserves. With the improvement of graphite product processing technology, it has been widely used in fields such as chemical engineering, smelting, casting, new materials, molds, aerospace, etc. We often see many chemical properties of graphite products in the industry, such as graphite crucibles, graphite heaters, graphite molds, etc(1) High temperature resistance: In smelting, the melting point of graphite products is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with temperature, and at 2000 ℃, the strength of graphite doubles.(2) Good conductivity and thermal conductivity: The conductivity of graphite products is 100 times higher than that of ordinary non-metallic minerals. The thermal conductivity exce

What are the characteristics of graphite board?

Graphite boards are generally used in industrial production such as metallurgical industry, chemical plants, and photoelectric catalysis. So what characteristics does it be so common to promote it in this field?Six characteristics of graphite board1. Easy process performance of graphite board: graphite board can be cut into different sizes, appearances, and thin thickness. It can give the membrane cutting plane board, which can be thinned from 0.05 to 1.5m.2. The heat resistance of graphite board: The maximum temperature of the graphite board can reach 400 ° C, at least less than -40 ° C.3. High -transmission thermality of graphite board: The thermal conduction rate in the plane map of the graphite board can achieve 1500W/mk, the heat transfer coefficient is 40%lower than that of aluminum, 20%lower than the copper.4. The coordination ability of graphite board: The graphite board is very easy to make a multi -layer board with metal materials, cable shestages or double -sided tape to en

The purpose of graphite machining

Various carbon graphite products, although they have a certain shape and size after forming, undergo expansion and contraction, deformation and bending, collision or corner dropping during the process of roasting, impregnation, and graphitization treatment from the pressed blank to the graphitized blank. The surface adheres to some fillers and insulation materials, resulting in roughness and unevenness. Their shape and size change to a certain extent, and they cannot achieve the shape of the product during use, Due to strict requirements for size and surface roughness, it cannot be used without mechanical processing. In addition, some products have complex structures and shapes that cannot be directly produced by forming methods, such as metal continuous casting and rolling graphite crystallizers, electric spark machining graphite molds, carbide sintering graphite boats, discs, and other special graphite products. Some products require interconnection when used, such as the connection

The balance of graphite mineral exploitation and environmental protection

Insufficient technical investment in domestic graphite powder production enterprises

As a policy of each graphite deep processing production company, it is far from reality. The single product function is not bad, but the stability of batch production is doubtful, and the consistency of each batch of products cannot be guaranteed. A professor of deep processing and production of graphite powder believes that the exchanges of different types of different types of information for the deep processing and production of graphite powder will be a long process. The gap between many companies is that they have excellent experiments but cannot produce in batches. The following editors analyze the reasons for the lack of technical investment in domestic graphite powder production enterprises:It is not related to the automation control of the company's production line, which is a systematic problem. At present, graphite powder deep processing production equipment accounts for more than half of the imported equipment. Graphite mineral resources are a very important strategic reso
