Corrosion-resistant plastic pumps are generally made of FRPP, CPVC, PVDF, FEP, PTFE, PVC, and are resistant to acids and alkalis and other corrosion-resistant liquids. Transportation of corrosive media in chemical production, chlorine water wastewater treatment and acid addition process in ion membrane caustic soda project, electricity in non-ferrous metal smelting
Corrosion-resistant plastic pumps are generally made of FRPP, CPVC, PVDF, FEP, PTFE, PVC, and are resistant to acids and alkalis and other corrosion-resistant liquids. Transportation of corrosive media in chemical production, chlorine water wastewater treatment and acid addition process in ion membrane caustic soda project, electrolyte transportation in non-ferrous metal smelting, pickling process in automobile manufacturing, and pharmaceutical, petroleum, power, electroplating, Dye, pesticide, paper, food, textile and many other industries.
Introduction to the scope of application of corrosion-resistant plastic pump materials
1.FRPP --- glass fiber reinforced polypropylene
Generally used for weak acid and alkali liquid.
Do not use for oxidizing strong acid liquid, strong alkaline liquid. The liquid temperature must be below 65 ° C.
2.CFRPP --- carbon fiber reinforced polypropylene
Generally used for weak acid and alkali liquid, stronger alkali resistance than FRPP.
Do not use for oxidizing strong acid liquid, strong alkaline liquid. The liquid temperature must be below 65 ° C.
3.CPVC --- high temperature chlorinated polyvinyl chloride
Generally used for strong oxidizing acids and high concentrations of bases, acids, chlorinated hydrocarbons, lipids, ketones and chlorine up to 90 ° C. Such as sodium hydroxide, chromic acid, potassium permanganate, etc.
Do not use in solvents and liquids under low temperature (<0 ℃).
4.PVDF --- polyvinylidene fluoride
Generally used for acid resistance, acid mixture, bromine and pure media. High temperature resistance. Can be used for strong oxidizing acids. Can be used for high concentration of hydrochloric acid, sulfuric acid, nitric acid, etc.
Do not use in highly demanding solutions, PH> 12. Such as high concentration of sodium hydroxide, sodium carbonate.
5.FEP --- polyperfluoroethylene propylene
Generally used, strong acid, strong alkali, suitable for any corrosion-resistant liquid (no problem as long as it is corrosive), is currently the most widely used, the best effect of acid and alkali resistant materials. At present, no resistance has been found. Corrosive liquids react chemically.
Lvhuan Pump Industry is a professional manufacturer of corrosion-resistant chemical pumps . It specializes in the production of FEP --- polyperfluoroethylene propylene corrosion-resistant chemical pumps . At present, it has a very good effect in various chemical and other fields.
