Lining material |
Main Performance |
Applications |
Teflon |
1.The most steady material in plastics which is resistible to boiling hydrochloric acid, vitriol fortis as well as strong alkali and organic impregnates. Â Â Â Â
2.Not be perfect in abrasion resistance. |
Strong corrosive mediums such as strong acid and alkali |
F46 |
1.Have the same abrasion resistance with PTFE.
2.Resistable for low abrasion.
3.Having strong resistance to load pressure. |
1.The same as PTFE.
2.Applicable in mediums of low abrasion. |
Neoprene |
1.Be of good elasticity, retractility and abrasion resistance.
2.Be resistant to low acid, alkali and salt but not for oxidation mediums. |
Water, sewage and slurry, mineral serosity of low abrasion. |
Polyurethane |
1.Be of good abrasion resistibility.
2.Not be perfect in acid/alkali resistance.
3.Can't be used for water mixed with organic impregnants. |
Applicable in mineral serosity, slurry and coal slurry of high abrasion. |
Â
Main performances of the electrode materials |
Electrode material  |
Applications |
Stainless steel SS316 |
Applicable in water, sewage and corrosive mediums. Widely used in industries of petrol, chemistry, carbamide, etc. |
Hastelloy B(HB) |
Having strong resistance to hydrochloric acid of any consistence which is below boiling point. Also resistible against vitriol, phosphate, hydrofluoricacid,organic acid etc which are oxidable acid, alkali and non-oxidable salt. |
Hastelloy C(HC) |
Be resistant to oxidable acid such as nitric acid, mixed acid as well as oxidable salt such as Fe+++,Cu++and sea water |
Titanium |
Applicable in seawater, and kinds of chloride, hypochlorite salt, oxidable acid (including fuming nitric acid), organic acid, alkali etc. Not resistant to a pure reducing acid(such as sulphuric acid, hydrochloric acid)corrosion. But if acid contains antioxidant(such as Fe+++,Cu++) is greatly reduce corrosion. |
Tantalum |
Having strong resistance to corrosive mediums that is similar with glass. Almost applicable in all chemical mediums. Except for hydrofluoric acid, oleum and alkali. |
Platinum-iridium |
Almost be applicable in all chemical mediums except for aqua fortis, ammonium salt.
