High pure graphite generally refers to graphite with carbon content of more than 99.99%. It can be divided into three types: coarse particle structure, fine particles structure, and ultra -fine particle structure in the tissue structure. In the furnace. The basic materials of the integrated circuit are mainly silicon single -crystal chips. The current growth process of silicon single crystal mainly adopts a direct pull (CZ) method. Other methods include the magnetic field direct pull method (MCZ), the area (FZ) method, and the double -yarm pull crystal method Law, the global electronic industry uses straight single -crystal silicon to account for 80% of the total amount of single crystal silicon. The graphite in the direct pull single crystal silicon furnace is consumables. Heating system. In 2005, China needed a straight silicon single -crystal furnace to use about 800 t.
Another important purpose of high pure graphite is processed into various types, which are used to produce precious metals, rare metals or high -purity metals, and non -metal materials. Graphite electrode is also a high -purity graphite, which can be used for spectral chemical analysis of all elements except carbon. Spectral analysis is formed with graphite electrodes. The content of the impurities of the finished product should not be greater than 6*10 to prepare standard samples in the spectral analysis and use chemical methods to capture impurities with a spectrum pure charcoal or spectrum pure graphite powder. It is 6 *10; in terms of certain uses, the carbon content is needed to reach 99.9995%, and the total gray content is less than 5 *10. The molding method of high pure graphite has three types: squeezing molding, molding molding, and static pressure molding. Table 9 is an example of the physical and chemical performance indicators of high -pure graphite products produced in China.
2024-03-19Graphite plays a pivotal role in battery technology. As a negative electrode material for lithium-ion batteries, graphite has become a key component of modern battery technology due to its excellent lithium storage performance and cycle stability.
The antioxidant treatment process of battery -specific graphite includes material preparation, weight, impregnation liquid preparation, impregnated electrode treatment and dry treatment. After graphite electrode processing, it can be processed into various specifications of graphite electrode products. The processed graphite electrode is the same as the unsolvioing graphite electrode. Compared with graphite electrodes, it has the characteristics of smooth surface and good conductivity. The intensity of mechanical design can increase by 50-60%, the pore rate gradually decreases by 10-15%, and the consumption of electrode material can be reduced by 20-25%. Electrical consumption can be reduced by 20-25%.The anti -oxidant treatment of battery -specific graphite has the attributes as follows:(1) Preparation material weighing: weigh the graphite electrode, provide qualified processing materials;(2) Preparation and heating of penetrating solution: The composition of the impregnation solutio2023-07-18Antioxidant treatment method for battery dedicated graphite
2023-04-03In recent years, graphite molds have continued to impact model shell sales markets with their high -quality characteristics, and have become the new darling of the machinery processing industry. The manufacturers of Kobwee Grapeite products below told everyone that the shortcomings and preventive methods of the heat treatment process of graphite mold.
The functional fillers of scales are mainly used for anti -corrosion coatings, fireproof coatings and conductive coatings.As an anticorrosive material, it has a good rust -proof primer made of charcoal black, talc powder and oil. It has good chemical resistance and solvent corrosion performance. If you add chemical pigments such as zinc yellow to the formula, its rust -proof effect is better. EssenceIt is used as a fireproof filler. It is expandable graphite. It is a graphite intervertebral compound obtained by natural graphite scales. 300 times) suffocating the flame, and at the same time, the expansion material is generated to achieve the effect of isolation of the flame, delay or interrupting the flame spread, and it is not burning, soft, high on the surface, and good coach layer. However, the volume and dosage of the expansion body should be appropriate. Tests show that 150um particles, 30%expansion multiple, and 5%of the amount are the most suitable.Scales graphite can be directl2023-04-18The application of scales graphite in the coating industry
