Graphite heat exchanger is an environmentally friendly equipment made of graphite. It has good corrosion resistance, is not easy to scale on the heat transfer surface, and has good heat transfer performance. The graphite used to make the heat exchanger should be impermeable. The structure of the graphite heat exchanger Different and different, the mechanical processing performance of impermeable graphite is similar to that of cast iron. Due to the poor strength and brittleness of graphite itself, the production of impermeable graphite equipment in China is currently mainly based on artificial graphite. In the manufacturing process, due to high temperature baking The volatile matter escapes, resulting in the formation of many fine pores, and sometimes cracks. If the porosity is too large, the amount of grease will be too large during the immersion process, and the manufactured products will have poor heat transfer. Two processing methods are used to improve its strength and ensure processing accuracy. During any handling of the graphite heat exchanger equipment, it must be handled with care, and it is strictly forbidden to throw it indiscriminately, and it is strictly forbidden to hit with a metal hammer. If it is difficult to use, use a mallet with a rubber to beat.
