Why can graphite blocks be used as sealing rings

Time：2023.09.21Browse：1: Share:

In the graphite industry, it is well known that graphite products are widely used in many industries. It is believed that friends who often walk in graphite rings know about graphite sealing rings. So why is graphite used as a sealing material? This is a question worth exploring.

Graphite has characteristics that cannot be replaced by other metal materials, such as conductivity, good thermal conductivity, and excellent corrosion resistance. Choosing it as a sealing material also has its own special characteristics. Carbon graphite rings have physical and mechanical properties such as high temperature resistance, self-lubrication, low friction coefficient, wear resistance, and low thermal expansion coefficient. Therefore, graphite sealing rings can be seen in various industrial sectors such as papermaking, textile, and medicine.

Moreover, graphite blocks can not only be used as graphite sealing rings, but also as various types of graphite machined parts in other industries.

Preparation process and application of ultrafine graphite powder

Ultrafine graphite powder is one type of graphite powder. The raw material of ultrafine graphite powder is natural flake graphite, which is crushed using an airflow grinder or ultrafine micro grinder. Ultrafine graphite powder with a particle size of 6-10 μ m. It's ultrafine graphite powder.The preparation process of ultrafine graphite powder is as follows: natural flake graphite and raw material coke enter the crushing chamber through a feeding injector with compressed air, and are distributed at the nozzles outside the crushing chamber to inject ultra-high speed airflow into the crushing chamber, causing the coke powder to collide and rub with each other at high speed to form micro powder. The airflow with micro powder is discharged into the grading chamber through the outlet pipe, separating the coarser particles and being crushed again through the return pipe, The remaining micro powder is collected in stages using a cyclone separator and a bag collector. Ultrafine graphite powder

Purification method of graphite

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has lower costs. This is a major advantage of the flotation method for purifying graphite. However, when using the flotation method to purify graphite, it can only achieve a limited improvement in the grade of graphite. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomers, but also is not conducive to protecting the large flakes of graphite. Therefore, using flotation to further improve the graphite grade is not economical or scientific. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） Chlorination roasting methodThe low roasting temperature and low chlorine consumption of the chlorination roasting method greatly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after tr

What role does flake graphite play in our lives

Graphite is divided into two types: natural graphite; The second is artificial graphite. Although with the improvement of manufacturing technology, the function of artificial graphite is no less than that of natural graphite in many cases, natural graphite has always maintained its unique advantages in some fields.Among natural graphite resources, flake graphite (crystalline graphite) has low reserves and high value. It has good conductivity, thermal conductivity, lubrication, and oxidation resistance, and is widely used in industries such as metallurgy, machinery, chemical engineering, refractory materials, aerospace, etc. It is one of the indispensable non-metallic materials for the development of high-tech today.Natural flake graphite peelingThe flake graphite structure is flaky and has good surface properties, making it one of the best floatable minerals in nature. According to the size of the scales, flake graphite can be divided into large flake graphite (with particle sizes of

The main methods of graphite purification

1 Flotation methodFlotation method is a commonly used method for purifying minerals. Due to the difficulty of water infiltration on the surface of graphite, it has good floatability and is easy to separate from impurity minerals. In China, flotation method is generally used for beneficiation of graphite.The flotation of graphite raw ore generally uses the positive flotation method first, followed by reverse flotation of the positive flotation concentrate. High grade graphite concentrate can be obtained by using flotation method. The grade of flotation graphite concentrate can usually reach 80% to 90%, and the purity can reach around 98% by using multi-stage grinding.The commonly used collectors for flotation of crystalline graphite are kerosene, diesel, heavy oil, sulfonic acid esters, sulfate esters, phenols, and carboxylic acid esters. The commonly used foaming agents are 2 # oil, 4 # oil, terpineol oil, ether alcohol, and butyl ether oil. The adjusting agents are lime and sodium ca

What are the quality requirements for graphite electrodes used in DC arc furnaces

The graphite electrode used in DC arc furnaces has no skin effect when current passes through, and the current is evenly distributed on the current cross-section. Compared with AC arc furnaces, the current density passing through the electrode can be appropriately increased. For ultra high power electric furnaces with the same input power, DC electric arc furnaces only use one electrode, with a larger electrode diameter. For example, a 100t AC electric arc furnace uses electrodes with a diameter of 600mm, while a 100t DC electric arc furnace uses electrodes with a diameter of 700mm. Larger DC electric arc furnaces even require electrodes with a diameter of 750-800mm, and the current load is also increasing. Therefore, the following requirements are put forward for the quality of graphite electrodes:(1) The resistivity of the electrode body and joints should be smaller, such as the resistivity of the electrode body dropping to 5 μ Around Ω. m, the resistivity of the joint decreases to
