Main performances of the lining materials
  Lining material   Main Performance   Applications
  Teflon   1.The most steady material in plastics which is resistibal to boiling hydrochloric acid,vitriolandqua fortis as well as strong alkali and organic impregnates.        2.Not be perfect in abrasion resistance.   Strong corrosive mediums such as strong acid and alkali
  PFA   Having the same abrasion resistance with PTFE.Having strong ability of load pressure resistance.   Applicable in state of load pressure
  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 aicd,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 resisitance.3.Can't be used for water mixed with organic impregnants.   Applicable in mineral serosity,slurry and coal slurry of high abrasion.


  Main performances of the electrode materials
  Electrode material   Applications
  Stainless steel SUS316   Applicable in water,sewage and corrosive mediums.Widely used in industries of petrol,chemistry,carbamide,etc
  Stainless steel     covered with tungsten carbide   Applicable in mediums of no corrosive and low abrasion.
  Hastelloy B(HB)   Having strong resistance to hydrochloric acid of any consistance which is below bioling piont.Also resistable 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.
