High -pure scales graphite has good high temperature resistance, conductivity, high -pure graphite thermal conductivity, lubrication and chemical stability. Graphite manufacturers are widely used in metallurgical, machinery, environmental protection, chemical, fire, electronics, medicine, military, military, aerospace and other fields. Its status in the national economy is becoming more and more important, and it is an indispensable and important non -metal raw material for modern industry and high -tech development. Trace impurities have a great impact on the performance of graphite products. The higher the carbon content of high pure scales, the better its performance as a functional material.
In order to analyze the trace impurities in high pure scales, the sample is usually grayed or wet to digest to remove carbon, dissolved ash with acid, and then determined the impurities in the solution. The grayization method does not need to dissolve gray with ultra -pure acid, avoiding the risk of introducing elements to be introduced, so it is widely used. The detection of high -pure scales graphite gray content is very difficult, because high temperature combustion is required to enrich the gray score, and the ash branch will stick to the sample boat at high temperature, which is difficult to separate, resulting in the ingredients and content of impurities that cannot be accurately determined.
The existing method is to use the characteristics of platinum non -response to acid. Burn the high pure scales with platinum crickets to enrich graphite, and then directly dissolve the sample with acid heating. The impurities in the scale graphite can be calculated by measuring the composition in the solution. However, this method has a certain limitations, because high -purity scales graphite contains a large amount of carbon, which will make platinum crickets crispy at high temperatures, which can easily lead to the break of platinum. Because traditional methods cannot detect the impurities in high pure scales, it is necessary to improve the detection method.
Scales are widely used in high -grade refractory materials and coatings in the metallurgical industry. Such as magnesium carbon bricks,。, etc. The stabilizer of industrial explosives, desulfurization promoters of the smelting industry, pencil cores of light industry, carbon brushes of the electrical industry, electrodes of the battery industry, catalysts of the fertilizer industry, etc. After deep processing of graphite, graphite can be produced, which can be used as lubricants, molding agents, brushes, and conductive coatings. It can also produce expansion graphite for raw materials for flexible graphite products, such as flexible graphite seals, flexible graphite composite products, etc.
Skin graphite, as a functional filler for coatings, is mainly used for anticorrosive coatings, fireproof coatings and conductive coatings. As an anticorrosive material, it is a rust -proof primer made of charcoal black, talc powder and oil. It has good chemical resistance and solvent resistance. If you add chemical pigments such as zinc yellow to the formula, the rust -proof effect will be better.
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.
Many new main uses of graphite have long been developed and designed with the development trend of scientific and technological progress. Graphite has many new main uses. High -purity graphite products are used for high -purity metallurgical industry, electronics industry, Chinese nuclear industry and mold processing; general graphite products can be used as a wall -building raw material for mining with aluminum electrolytic grooves, non -metallurgical tunnel furnaces, and non -ferrous metal furnaces. Calcium residual raw materials can be used as carbon increases for ironmaking industry. There are many types of carbon quality raw materials used to seepage nitrogen, including artificial synthesis of graphite, petroleum coke, casting focus, and pure natural graphite.Graphite products are at least within 2000 degrees. This is because carbon must be graphite at a high temperature natural environment of 2000-3300 degrees at a high temperature and natural environment of at least 10 days and2023-03-08Many new main uses of graphite have already been developed and designed
