Graphite products are widely used in the chemical industry because of their excellent chemical stability, high temperature resistance, electrical conductivity and lubricity. Here are some of the main application areas:
1. Corrosion-resistant materials: Graphite has very good corrosion resistance and can be used to make parts of chemical equipment, such as pumps, valves, pipes and reactor linings to prevent chemical corrosion.
2. Heat exchanger: Graphite has excellent thermal conductivity and is often used in the manufacture of heat exchangers, especially in applications where corrosive or high-temperature media need to be handled.
3. Electrode Material: The conductivity of graphite makes it an ideal material for electrodes in electrolyzers, which are widely used in chlor-alkali industry, water electrolysis to hydrogen production, etc.
4. Catalyst Carriers: Graphite's porosity and chemical stability make it ideal for catalyst carriers to improve the efficiency of chemical reactions.
5. Lubricants: The lubricating properties of graphite allow it to be used as a lubricant, especially for mechanical parts in high temperature or chemically corrosive environments.
6. Sealing Material: Graphite's self-lubricating and high temperature resistance make it an ideal material for sealing gaskets and sealing rings to prevent the leakage of chemicals.
7. Pump Components: Graphite's abrasion and corrosion resistance makes it suitable for use in the manufacture of mechanical seals and bearings for chemical pumps.
8. Filters & Screens: The porosity of graphite allows it to be used in the manufacture of filters and screens for separating solid particles and liquids.
9. Reactor Lining: Graphite's high temperature resistance and chemical stability make it suitable as a lining material for high-temperature reactors.
10. Laboratory Equipment: Graphite products such as crucibles, mortars and electrodes are also widely used in chemical laboratories.
11. Graphene: As a new type of graphite material, graphene also has potential applications in the chemical industry, such as as as a catalyst or in nanocomposites.
12. Graphene membranes: Graphene membranes have potential applications in separation technology due to their unique selective permeation properties.
