Molded impermeable graphite plates possess excellent physical and mechanical properties and the same chemical stability as impregnated graphite plates. Because they are produced by molding, the plates are regular in shape, easy to use, and save material. Molded graphite plates have a neat and aesthetically pleasing surface, and the joint gap is easy to control.
The corrosion resistance of molded impermeable graphite plates mainly depends on the corrosion resistance of the resin. Except for strong oxidizing media (such as nitric acid, chromic acid, concentrated sulfuric acid, etc.), molded graphite plates are resistant to most inorganic acids, organic acids, salts, organic compounds, and solvents, but are not resistant to strong alkalis.
Molded impermeable graphite plates possess the advantages of impregnated graphite plates, including good physical and mechanical properties, chemical stability, and oil resistance.
Molded impermeable graphite plates offer superior strength, wear resistance, and impermeability compared to impregnated graphite plates.
Molded impermeable graphite plates have a short production cycle, advanced technology, and low cost. They possess a uniform structure, are formed by compression molding, resulting in regular plate shapes that facilitate construction and have a wide range of applications, making them an ideal and highly recommended anti-corrosion lining material.
Currently, most molded graphite plates are produced using 2130# phenolic resin as a binder. A small quantity of molded graphite plates using furan resin as a binder has also been produced. Further research is needed to develop graphite products suitable for different media conditions, such as water glass graphite products, which can be used in high-temperature oil and gas environments at 380-420°C, solving corrosion problems under these conditions.
