Material characteristics of graphite powder

Graphite powder is a substance that is very sensitive to chemical reactions. In different environments, its resistivity will change, which means its resistance value will change. However, there is one thing that does not change. Graphite powder is one of the good non-metallic conductive substances. As long as the graphite powder is kept uninterrupted in an insulated object, it will also be electrified like a thin wire. However, there is no accurate number for the resistance value, Because the thickness of graphite powder varies, the resistance value of graphite powder will also vary when used in different materials and environments. Due to its special structure, graphite has the following special properties:1) High temperature resistant type: The melting point of graphite 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 te

What are the nature of ultra -fine graphite?

Ultra -fine graphite powder is one of the categories of graphite powder. The raw material of ultra -fine graphite powder is natural scales graphite. The airflow crusher or ultra -fine pieces is used to crush the natural scales graphite. The particle size of ultra -fine graphite powder reaches 6 ~ 10 μm, which is the ultra -fine graphite powder.The preparation process of ultra -fine graphite powder is: natural scales graphite and raw materials focus from compressed air to enter the crushed room by adding feed sprayer, sprayed in the crushing room, spray ultra -high -speed airflow at the crushed room , Fricate into microfimm, with a microfimm airflow, discharge from the exit tube into the hierarchical room, separate the thicker particles, and crushed it again by the rebate tube. Ultra -fine graphite powder was produced.Ultra -fine graphite powder can be widely used in the fields of conductive materials, wear -resistant lubricating materials, atomic energy industry and national defense i

What kind of crushing of graphite blocks can be divided into?

The crushing of graphite blocks can be divided into three items, do you know? Let's take a look at it together!1. Pre -fragmentation (or crushing): This also refers to the crushing of block -shaped graphite block raw materials after entering the factory. Generally, it refers to crushing the block of the block of 200mm to 50 ~ 70mm. EssenceSecond, medium crushing: This also refers to the granularity of graphite block raw materials after forging to the particle size necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Third, fine grinding (or grinding): It is grinding part of the raw material of graphite blocks to 0.15mm or 0.075mm particle size below. Every time it goes through, the granularity of the raw materials has become smaller. The larger diameter of the large raw material before crushing is the ratio of the diameter of the larger block of the raw material after crushing, which is called a crushing ratio.

Introduce the asphalt rubber pendant penetration processing process

The general operating process of graphite immersion is after being loaded into the product, first vacuum packaging (gas in the gas in the pores in the pores of the product) and then put it in the impregnation agent to submerge the product, then pressure it to the liquid level, so that Essence It is used for different intentions, and the standards of impregnation agent processing process are not thorough. Below, I will introduce the asphalt rubber mud impregnation processing process of graphite board in detail.The whole process of processing the processing technology of asphalt rubber -soaking small graphite board, electrode connector and its graphite anode board:First of all, the semi-finished processing surface of the graphite board was burn, and then put it into the product box and put it in the temperature of about 4 hours in the temperature of about 240-Soot. After the heat, the product is quickly installed into the impregnation tank with the iron frame (the immersion can be heate

The use of scales graphite and colloid graphite

Scales graphite is a very widely used non -metallic powder product, with good thermal conductivity, conductivity and lubrication effect; colloid graphite is a graphite product that uses natural scales graphite as the main raw material. There are certain differences in use. The following editor will introduce the purpose of scales graphite and colloid graphite:The scales graphite has a strong conductive capacity. It can replace the metal as a conductive material. The scale graphite can also be directly used as a carbon conductive filler or a composite conductive filler for conductive coating. The quality of scales graphite powder has a lot to do with its carbon content. Natural scales graphite collected from natural mines often contain a lot of impurities. It needs to be purified to get graphite powder with high carbon content because of high purity scales. The use of graphite is more widely used, providing an effective solution for the miniaturization and high integration of electroni

The Forming Process of Carbon Graphite Materials

There are various forming methods for carbon production, including four main methods: compression molding, extrusion molding, vibration molding, and isostatic pressing molding.Molding methodThis method uses a vertical press to make a mold according to the shape and size of the product. Then, a certain amount of mixed paste or powder is loaded into the mold on the press workbench. The press is started to apply pressure to the paste or powder, and maintained for a certain time to form it. Then, the pressed blank is ejected from the mold.The molding method can be divided into unidirectional pressing and bidirectional pressing, hot pressing and cold pressing according to different processes and equipment conditions. The molding method is suitable for pressing products with small size differences in three directions, uniform density, and high structural density and strength, but the products have anisotropy. Mainly used for producing electric carbon products and special graphite products.E

The case of graphite boat is harmful to the proportion of the surface layer

The harm of the shape of the graphite boat to the surface layer of the surface layer will use the new graphite boat and the use of the old graphite boat for more than three years to saturate the coating on the surface layer of the PECVD surface. The flat surface of the new graphite boat is good, and the graphite boat has the same conductivity. The plastic membrane molecular formula can be uniformly accumulated on the surface of the single crystal silicon wafer, and the uniformity between the pieces is higher.After the new graphite boat is saturated, there are still some plasma accumulated on the graphite boat when the accumulation is accumulated. When the number of running times is less than thirty times, as the number of running times increases, the plasma accumulated on the graphite boat decreases. Essence After the number of running times exceeds thirty times, as the number of uses increases, the inner wall of the graphite tape and the single crystal silicon tablets touch the plast

The role and use of graphite

Graphite is an allotrope of carbon with various excellent properties, and is therefore widely used in many fields. The following are the main functions and uses of graphite:

How to identify the quality of graphite board

The graphite board is not rusty for some manufacturers, but in fact many manufacturers have applied for more than ten years, and they are unclear how to distinguish the quality of graphite boards. This is only a kind of summary of the product, which is very vague.Speaking of how to distinguish the advantages and disadvantages of graphite boards, there is only one key, which is the relative density. The following discusses the necessity of using the Moore quality formula from many levels.The battery electrolyte is very prone to infiltration, resulting in the oxidation of the graphite board air, which is greatly shortened by the use period. The density is high, and the cost of application is increased, so it is important to choose a suitable graphite board manufacturer.2. In the field of resistance, the key to the graphite board is used to pad the method, which has a moisturizing effect. The relative density of the graphite board here is greatly displayed. Very easy to fall, the surface
