    Application and Introduction of Graphite Pillars

    Time：2023.10.11Browse：1

    Share:



    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 graphite


    1、 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 this, it can be seen that the high-temperature resistance of graphite is very outstanding.


    2. Special thermal shock resistance: Graphite has good thermal shock resistance, that is, when the temperature suddenly changes, the coefficient of thermal expansion is small, thus it has good thermal stability, and will not produce cracks during sudden changes in temperature.


    3. Thermal conductivity and conductivity: Graphite has good thermal conductivity and conductivity. Compared with ordinary materials, its thermal conductivity is quite high. It is 4 times higher than stainless steel, 2 times higher than carbon steel, and 100 times higher than ordinary non-metallic materials.


    4. Lubricity: The lubrication performance of graphite is similar to that of molybdenum disulfide, with a friction coefficient less than 0.1. Its lubrication performance varies with the size of the scale. The larger the scale, the smaller the friction coefficient, and the better the lubrication performance.


    5. Chemical stability: Graphite has good chemical stability at room temperature, and can withstand acid, alkali, and organic solvent corrosion.

    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.

    Graphite: the "black gold" mystery of natural minerals

    Graphite, this seemingly ordinary black mineral, actually contains endless mystery and value. As the "black gold" in natural minerals, graphite plays an irreplaceable role in many fields with its unique physical and chemical properties.Graphite has excellent electrical conductivity, thermal conductivity and chemical stability, which makes it widely used in electronics, metallurgy, chemical industry and other industries. At the same time, graphite is also an important raw material for the manufacture of pencil leads, lubricants and refractories. Its unique layered structure makes graphite also have broad application prospects in the field of energy storage.However, the mining and processing of graphite is not easy. Because of its low hardness, fragile and dust is easy to fly, it puts forward high requirements for mining technology and environmental protection. At the same time, with the continuous progress of science and technology, people's performance requirements for graphite are be

    Method for manufacturing low-density expanded graphite blocks using flexible graphite

    In recent years, various types of low-density carbon graphite materials have been actively studied, including carbon (graphite) foam made of mesophase pitch or polymer resin, and carbon nano foam formed when carbon materials are ablated by high repetition rate pulsed laser. Expanded graphite is also a low-density carbon graphite material. Due to the simple preparation process, low production cost, and convenience for large-scale industrial production of expanded graphite, research on expandable graphite has continued to deepen in recent years. The following editor from Jinhui Graphite Company introduced the method of making low-density expanded graphite blocks by soaking flexible graphite in concentrated acid:The worm like shape and weak macroscopic structure of expanded graphite limit its application.

    What is the difference between scales graphite and asbestos?

    1. Scale graphite has better high temperature resistance performanceThe scale of the scale graphite enhanced composite pads can withstand the high temperature of 1650 ° C. Even if the chemical equipment is melted, it is still safe and intact. When the asbestos products are at 500 ° C, the crystalline water inside will decompose to make itself powder and lose its effect. In many industrial fields, it is carried out at high temperatures. The nature of scales graphite makes it more suitable for this role.2. Synthine graphite is easier to useThe pads of scales graphite are only half of asbestos products, which means that to achieve the same sealing effect, the power of tightening the screw can be much smaller. The scales graphite not only has the above obvious characteristics, but also has excellent sealing performance, good compression, elasticity, elasticity, elasticity, The characteristics of good antioxidant, strong self -lubrication and plasticity, good conductivity, high gravity, an
