Selection of lining:
| Lining material | Performance | scope of application |
| chloroprene rubber Neoprene | Good wear resistance, excellent elasticity, high tensile strength, and resistance to corrosion from low concentration acid-base salt media, but not resistant to corrosion from oxidizing media. | <80 ° C, general water, sewage, mud, slurry |
| polyurethane Polyurethane | Has excellent wear resistance, but slightly inferior acid and alkali resistance. | <60 ° C, neutral and strongly worn mineral slurry, coal slurry, and mud. |
| PTFE PTFE | A material with the most stable chemical properties, capable of withstanding boiling hydrochloric acid, sulfuric acid, nitric acid, aqua regia, concentrated alkali, and various organic solvents, but not resistant to chlorine trifluoride and high-temperature sulfuric acid. | <180 ° C, strong corrosive media such as concentrated acid and alkali, sanitary media. |
| F46 | Chemical stability, electrical insulation, lubricity, non adhesiveness, and non flammability are similar to PTFE, but F46 material has better strength, aging resistance, temperature resistance, and low-temperature flexibility than PTFE. Good adhesion to metal, better wear resistance than PTFE, with good performance | <180 ° C, hydrochloric acid, sulfuric acid, aqua regia, and strong oxidants, sanitary media |
Selection of electrode materials:
| material | Corrosion Resistance |
| 316L | For nitric acid, sulfuric acid at room temperature<5%, boiling phosphoric acid, alkaline solution; Under certain pressure, media such as sulfurous acid, seawater, and acetic acid have strong corrosion resistance. |
| Hastelloy HB | Resistant to all concentrations of non oxidizing acids, bases, and non chlorinated hydrochloric acids such as hydrochloric acid, sulfuric acid, and organic acids at boiling point. |
| Hastelloy HC | Resistant to oxidizing acids such as nitric acid, mixed acids, or mixtures of chromic acid and sulfuric acid, as well as oxidizing salts and seawater |
| titanium | It can withstand corrosion from seawater, various chlorides and hypochlorites, oxidizing acids (including fuming nitric acid), organic acids, alkalis, etc. It is not resistant to corrosion from relatively pure reducing acids (sulfuric acid, hydrochloric acid), but corrosion is greatly reduced when the acid contains oxidants (such as nitric acid and media containing Fe and Cu ions). |
| tantalum | It has excellent corrosion resistance similar to glass, and can withstand almost all chemical media (including boiling point hydrochloric acid, nitric acid, and sulfuric acid below 175 ° C) except concentrated sulfuric acid. It is not resistant to corrosion in alkali. |
