What are the uses of flake graphite in the conductive industry

We all know that flake graphite has good conductivity, so in many conductive fields, flake graphite is chosen to be added to the products produced to achieve the best use effect. So what are the actual uses of flake graphite in the conductive industry? Below are one or two examples of flake graphite used in the conductive industry:1. The application of flake graphite as electrode material.As a new type of nanoscale carbon material, flake graphite not only has excellent conductivity and adsorption, but also has good chemical stability, making it widely used in electrode materials.2. Preparation of polymer based conductive composites using flake graphite as a conductive filler.Scale graphite is one of the conductive filling materials, and the commonly used carbon black has advantages such as good conductivity, low friction loss, and low pollution. Moreover, the addition of scale graphite can greatly improve the conductivity of polymer materials, leading to the transition of polymers fro

The difference between scales graphite and expansion graphite

Scales graphite is a kind of natural graphite. After the mines, it is pure. The general shape is fish -like, so it is called scale graphite. The expansion graphite is that the scales graphite is washed by sourness and after interlocketing, and it can be used as a previous graphite to expand 300 times. You can make rolls and flexible graphite raw materials. Let me introduce you in detail the scales graphite and expandable graphite. the difference:1. The use of scales graphite is more widely used than expandable graphiteIn industrial production, in addition to the function of expanding graphite, scales graphite is much better than expanding graphite. Therefore, the practice of industry is more widely used.2. The production process of scales graphite and expansion graphite is differentScales graphite is mainly made of mechanical damage and grinding. The expansion graphite is mainly made of processing methods such as chemical acidic liquid impregnation, and the production process is more

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

Graphite board antioxidant solution increases the period of use

Graphite boards are used in many industries, and due to their different advantages, future use will be more common. Old iron is very concerned about the use of graphite boards. The solution of the antioxidant solution of graphite board can reasonably increase the use period.After the formation of graphite board, it must be solved by antioxidantization. Generally, antioxidants are used, which is a thick liquid state. The ingredients are heat -resistant nano -ceramic particles. In the natural environment of air oxidation within 1300 ° C in the application temperature of the graphite board, its antioxidant actual effect is very good. After a variety of specifications of graphite boards with pre -immersed in the antioxidant protective film, its liquid can penetrate into the pores of the graphite board, and produce a layer of 0.02mm antioxidant on the surface of the air holes and graphite molds. The sexual protective membrane is exactly the reasonable blocking gas of this layer of protecti

electronic effect

The load migration rate of graphene at room temperature is about 15000cm2/(v · s). This value exceeds 10 times the silicon material. More than twice. Under certain conditions such as low temperature, the load migration rate of graphene can even be as high as 250000cm2/(v · s). Unlike many materials, the electronic migration rate of graphene is less affected by temperature changes. At any temperature between 50 and 500K, the electronic migration rate of a single laye
