Here is a graphite absorber graphite material equipment in the field of anti-corrosion applications Not suitable for use, so it can not be used, polyethylene, polyvinyl chloride, polystyrene and other plastics and natural rubber, butyl rubber, fluorine rubber and other rubber materials resistant to phosphoric acid and hydrofluoric acid corrosion.
Here is a graphite absorber graphite material equipment in the field of anti-corrosion applications
In the chemical industry, medicine, metallurgy, textile, national defense, electronics, environmental protection and other areas of the national economy, due to the strong corrosiveness of the medium, the requirements of the equipment not only anti-corrosion, but also good heat transfer performance, how to avoid strong corrosive media corrosion of the equipment, so as to reduce the investment and maintenance costs of the equipment, improve production efficiency and profits, is the problem that each chemical enterprise always need to solve, next we look at the graphite absorber -Graphite material equipment in the field of anticorrosion, phosphoric acid, hydrofluoric acid and fluorine-containing media at high temperatures with strong corrosive, stainless steel, aluminum, magnesium, copper, and most alloys other than steel are corroded by phosphoric acid corrosion is serious, is not suitable for use, so it can not be used, polyethylene, polyvinyl chloride, polystyrene and other plastics and natural rubber, butyl rubber, fluoroelastomer rubber and other rubber materials resistant to phosphoric acid and hydrofluoric acid corrosion.
Fluorine has good corrosion resistance at high temperatures, but the price is too high, generally used in aerospace, military and other industries, rarely used in general chemical equipment, graphite absorber, impermeable graphite as the main material equipment.
Impermeable graphite is a kind of material that uses certain measures to fill the graphite voids to make it impermeable graphite, including impregnated graphite, pressure graphite and casting graphite, graphite absorber has excellent corrosion resistance and physical and mechanical properties, and can be used to manufacture anticorrosion equipment widely used in chemical industry.
The performance of graphite absorber is as follows:
1. Excellent corrosion resistance: various carbon and graphite have excellent corrosion resistance to various concentrations of hydrochloric acid, phosphoric acid and hydrofluoric acid including fluorine.
2. Certain high temperature resistance: the use temperature of impermeable graphite depends on the type of impregnated material, which can improve the antioxidant property of carbon and graphite and further increase the actual working temperature.
3. Good thermal conductivity, in addition to graphite, also has good thermal conductivity, higher than metal materials in non-metallic materials, thermal conductivity coefficient is twice that of carbon steel, stainless steel seven times, so it is suitable for heat transfer equipment.
4. The surface is not easy to construct: graphite and most of the medium "affinity" is very small, dirt is not easy to adhere to the surface, especially for condensing equipment and crystallization equipment.
Now, in our life, the use of graphite absorber equipment is more and more popular, the use of some graphite absorber equipment has a great impact on the development of our business, because graphite absorber manufacturer of some chemical raw materials in the production process is liquid, in order to save money, we have to clean them, the more common is the two-effect evaporation and concentration, which requires a graphite absorber to facilitate the boric acid Absorption effect.
I will not explain too much, thank you for watching, if you need graphite absorber customization can consult our company.
