graphite for electrolysis

Introduction to the characteristics and performance of graphite for electrolysis

With the development of high and new technology, the manufacturing process of graphite materials has been continuously improved, and graphite materials that can meet the needs of different EDM are emerging in an endless stream. The mold is the most widely used basic process equipment in industrial production, and the mold industry is the basic industry of the national economy. In modern industrial production, product parts are widely used in stamping, forging forming, die-casting forming, extrusion forming, plastic injection or other forming processing methods, matched with forming dies, so that blanks can be formed into parts that meet product requirements.

Graphite for electrolysis is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms to form a covalent molecule. Since each carbon atom emits an electron, those electrons can move freely, so graphite is an electrical conductor.

Graphite for electrolysis has good chemical stability. Specially processed graphite, which has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, and filters , Pump equipment. It is widely used in petrochemical industry, hydrometallurgy, acid-base production, synthetic fiber, papermaking and other industrial sectors, which can save a lot of metal materials.

graphite for electrolysis is used as casting, sand-finding, pressing mold and high temperature metallurgical materials: due to the small thermal expansion coefficient of graphite and the ability to withstand rapid changes in cold and rapid heat, it can be used as a mold for glassware. After graphite is used, ferrous metals can be used to obtain castings with precise dimensions and a smooth surface. High rate, can be used without processing or a little processing, thus saving a lot of metal. The production of cemented carbide and other powder metallurgy processes usually use graphite materials to make porcelain boats for compression molds and sintering. Single crystal silicon crystal growth crucibles, regional refining vessels, support fixtures, induction heaters, etc. are all made of high-purity graphite. In addition, graphite can also be used for vacuum smelting graphite heat insulation boards and bases, high-temperature resistance furnace tubes, rods, plates, grid sheds and other components.

Six excellent properties of graphite for electrolysis:

1. Excellent thermal and electrical conductivity

2. Good thermal stability and heat shock resistance, such as low linear expansion coefficient

3. Resistant to chemical corrosion and not easy to react with polymetals

4. Under high temperature (most copper matrix matrix sintering temperature is above 800℃), the strength increases with the increase of temperature

5. Has good lubrication and anti-wear properties

6. Easy to process, good mechanical processing performance, and can be made into molds with complex shapes and high precision.

Nowadays, the design of graphite for electrolysis has been transformed from a manual experience design method to a computer-aided design method. Modern graphite for electrolysis companies widely use computer-aided technology and artificial intelligence technology to make decisions. Simulation analysis and optimization design. At the same time, the application of database and computer network technology enables designers to share design materials, information, resources, and cooperate on a larger scale, which brings the overall level of modern graphite for electrolysis design to an unprecedented level.
