How to solve the corrosion of the device in the scale graphite?

How to avoid the corrosion of the equipment on the equipment, thereby reducing equipment investment and maintenance costs, and improving production efficiency and profits is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but not high temperature, but scales graphite has both advantages. The following editors will introduce the problem of the device corrosion in detail how to solve the equipment of the scales:1. Excellent thermal conductivity. Scales graphite also has good thermal conductivity. It is the only non -metallic material with a thermal conductivity higher than the metal. The thermal conductivity coefficient is 2 times that of carbon steel and 7 times that of stainless steel. Therefore, it is suitable for heat transfer equipment.2. Excellent corrosion resistance. Various types of carbon and graphite have excellent corrosion resistance to all concentrations of hydrochloric acid, phosphate, and hydrofluoric acid, includin

Purification method of graphite

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has lower costs. This is a major advantage of the flotation method for purifying graphite. However, when using the flotation method to purify graphite, it can only achieve a limited improvement in the grade of graphite. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomers, but also is not conducive to protecting the large flakes of graphite. Therefore, using flotation to further improve the graphite grade is not economical or scientific. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） Chlorination roasting methodThe low roasting temperature and low chlorine consumption of the chlorination roasting method greatly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after tr
