Graphite blocks are produced using three standard methods: molded, extruded, and isostatic pressing. Each process ensures the creation of high-density and uniform structures.
1. Molded: Compression molding is a transparent paste or pressed powder is placed into a mold of the desired shape and size. Under pressure, the particles interweave, resulting in a compact and durable block of graphite.
2. Extruded: The raw material undergoes pressure through the extrusion method as it passes through a die of a specific shape. Then compaction and plastic deformation produce with precise sizes and shapes.
3. Isostatic Pressing: We use isostatic pressing to create high-density, uniform structures. This unique manufacturing process involves subjecting the material to high temperatures and pressure. The result is the products with exceptional quality and durability. The manufacturing process cycle is generally longer, more than two months.
Jinsun carbon graphite blocks are classified according to different particle sizes, including medium-coarse, fine-grain and high-purity.
Excellent conductivity: They have high electrical conductivity, which helps improve current transmission efficiency.
High temperature resistance: It remains stable at high temperatures and is not easy to deform, making it suitable for high temperature applications.
Chemical inertness: It has good corrosion resistance to a variety of chemicals and extends its service life.
Mechanical strength: They have a strong structure and are wear-resistant, making them suitable for various industrial environments.
Easy processing: It can be easily cut, grooved or punched to adapt to special industrial applications.
Used in Electrolysis: They are indispensable as conductive 電極 materials in industries such as electrolytic metal, magnesium, nickel, and more. It has corrosion resistance, can resist the erosion of chemical media such as acids and alkalis, and maintains stable performance.
Metallurgical and Resistance Furnaces: They are used not only in metallurgical furnaces, resistance furnaces, but also in other applications requiring high temperature resistance and electrical conductivity.
Chemical Industry: They excel as furnace materials for corrosion-resistant heat exchange equipment and high-temperature furnaces. Large graphite block heat exchanger can meet the strict requirements of the chemical industry. Because they have higher specific resistance.
Foundry industry: You can make it into graphite mold for casting and smelting. Because its ultra-high density and compact structure are very suitable for smelting gold, silver and other precious metals.
Aerospace industry: They are resistant to high temperatures, light in weight, and high in strength. Therefore they are widely used in the aerospace and military industries.
