Scales graphite -related knowledge points

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.In the lithium ion battery material, the anode material is the key to determining the battery performance. As a graphite material with high crystal, the granularity of the scale graphite directly affects the ratio of the electrode comparison of the surface area and edge carbon atoms. Crucial role.Scale graphite has a high electronic conductivity, large lithium ion diffusion coefficient, high plug -in capacity, and low plug -in potential, which is one of the important materials for lithium batteries. Scale graphite can stabilize the voltage of the lithium battery, reduce the internal resistanc

How to maintain graphite processing into graphite stick products?

1. During the use of graphite stick products, the graphite stick products are turned once a week to extend the life of graphite stick products;2. Using an appropriate amount of combustion agent, additives will reduce the life of graphite sticks;3. Keep a proper distance between the graphite stick and the wall of the furnace, and the graphite stick products should be placed in the furnace positive;4. When removing the inside of the graphite rod product, the inside of the wall of the graphite and sticking should be tapped to prevent damage to damaging graphite rod products;5. Graphite products are strictly preventing humidity. They must be placed on a dry place or wooden stand during storage.

Artificial graphite application field

In the metallurgical industry, natural scales can be used to produce refractory materials such as magnesium carbon bricks and aluminum carbon bricks due to better antioxidant properties. Artificial graphite can be used as a steelmaking electrode, and the electrodes made of natural graphite are difficult to use to use the steelmaking electric furnaces with strict conditions.In the machinery industry, graphite materials are usually used for wear -resistant and lubricating materials. The lubrication of natural scales graphite is better, which is often used as additives for lubricating oil. The device that transports the corrosive medium is widely used by artificial graphite pistons, sealing rings and bearings. There is no need to add lubricating oil during work. Natural graphite and polymer resin composite materials can also be used in the above fields, but wear resistance is not as good as artificial graphite.In the chemical industry, artificial graphite has the characteristics of corro

Optical and mechanical properties of graphene

Graphene has excellent optical properties, with an absorption rate of about 2.3% over a wide wavelength range, making it almost transparent. Within the thickness range of several layers of graphene, with each increase in thickness, the absorption rate increases by 2.3%. Large area graphene films also have excellent optical properties, and their optical properties change wi

How is expanded graphite produced?

Due to the fact that graphite is a non-polar material, it is difficult to intercalate with small polar organic or inorganic acids alone, so oxidants are usually required. The chemical oxidation method generally involves soaking natural flake graphite in a solution of oxidants and intercalators. Under the action of strong oxidants, graphite is oxidized, causing the neutral network of planar macromolecules in the graphite layer to become positively charged planar macromolecules. Due to the extrusion effect of isotropic positive charges between positively charged planar macromolecules, the spacing between graphite layers increases, and the intercalation agent is inserted between the graphite layers to form expanded graphite.Expanded graphite will rapidly shrink when heated at high temperatures, with shrinkage times reaching tens to hundreds or even thousands of times. The apparent volume of contracted graphite reaches 250-300 milliliters/gram or more. The shrunken graphite is in the shap
