Application and Introduction of Graphite Pillars

The graphite column combines the wear resistance of copper alloy and the self-lubricating performance of solid graphite lubricant, making it unnecessary to refuel and maintain during use. The product is widely used for high load, intermittent or swinging movements, such as production lines for steam locomotives, water turbines, reservoir work/accident doors, plastic machinery, etc. According to the operating conditions used, various types of copper alloys can be provided.The main component of graphite column is graphite, and its performance is different from that of ordinary graphite1、 The production and processing technology characteristics of graphite pillars:1. High temperature resistance: Graphite is currently one of the most high-temperature resistant materials known. Its melting point is 3850 ℃± 50 ℃, and its boiling point reaches 4250 ℃. It is subjected to an ultra-high temperature arc at 7000 ℃ for 10 seconds, with the smallest loss of graphite, which is 0.8% by weight. From t

Graphite powder has the cause of self -lubrication performance analysis

Graphite powder is a wear -resistant material, and its self -lubrication performance is its most important feature. Graphn powder has a good self -lubrication performance due to its special layer -shaped crystal structure. The following are the analysis of the reasons for the self -lubricating property of graphite powder:The carbon atoms in graphite lattles are arranged in hexagonal on different planes. The distance between the carbon atoms in the same plane layer is 1.42 meters, and the distance between the carbon atom of each plane layer is 3.35. They are staggered along the same direction, repeat the position of the first plane in the third plane, the fourth plane repeats the position of the second plane, and so on. In each plane layer, because the carbon atoms are relatively tight, the binding forces between them are relatively large, and the carbon atom between layers and layers is far from each other, which is easy to separate and relatively slide. This is the main reason why gr

What are the scope of application of graphite anode?

High -purity graphite board is made of high -quality high -purity graphite. High -purity graphite refers to the carbon content of graphite more than 99.99%. High -purity graphite producers use oil coke as raw materials. Production, after the production of rigorous high -purity graphite processing process. High -purity graphite has excellent characteristics such as good conductivity, heat resistance, acid suppression, alkali etching, and easy production and processing. High -purity graphite products are generally used to refractor and thermal insulation materials and building coatings in the metallurgical industry. , Pencil core in the light industry, motor carbon brush produced by the electrical equipment industry, electrical grade of electricity production produced by the rechargeable battery industry, and the production of metal catalysts in the organic fertilizer industry.The anode oxygen graphite board is also called graphite positive film, graphite positive rod, which has high -q

Classification of graphite blocks

Classification of graphite blocks of graphite block classification of graphite blocksThe crushing of graphite blocks can be divided into three items, do you know?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.Middle crushing: This also refers to the granular block of graphite blocks that is further broken until the granularity necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Essence (or grinding): It is the following powders to grind some graphite raw materials to 0.15mm or 0.075mm particle size. 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 crushi

Graphite: the natural king of electricity

Graphite, this dark gray mineral, is known as the "natural king of electricity" because of its excellent electrical conductivity. Its electrical conductivity is better than many other materials, making graphite occupy a pivotal position in the electronics industry. Whether it is the manufacture of electrodes, batteries or other electronic devices, graphite plays an irreplaceable role.In addition, graphite ha

The key features of graphite

1. High fever and conduction: In response to the use of raw materials such as graphite with high thermal conductivity, it reduces the time of fusion.2. High temperature resistance: high -temperature resistance has strong impact characteristics, for rapid cold and hot heat, not easy to crack.3. High temperature resistance: high fire resistance, high temperature to 1200 to 1600 ° C.4. Anti -corrosion resistance: strong adhesion to resist melting soup.5. Anti -reflective impact: have a certain anti -reflective impact resistance (when the funds of the melt material are invested, etc.).6. Antioxidant: Graphite is very easy to oxidize at high temperatures in oxidation. Due to the development of oxidation solution, oxidation consumption is less.7. Anti -adhesion: Because graphite is not easy to stick to the soup, the molten soup is soaked and attached with less adhesion.8. There is very little environmental pollution of metal materials: Because there is no bad matter that infiltrate the envi
