Tšebeliso

Perfluoropolyethers (PFPE) e qalile ho ithutoa ka bo-1960.Ke mofuta oa li-perfluoropolyethers tse khethehileng.Ka karolelano boima ba limolek'hule bo tloha ho 500 ho ea ho 15000. Ho na le C, F, O feela likarolo tse tharo tsa buka ea lik'hemik'hale molek'hule.E na le litšoaneleho tsa ho hanyetsa mocheso, khanyetso ea oxidation, ho hanyetsa mahlaseli, ho thibela kutu, ho se timetse, joalo-joalo. E 'nile ea sebelisoa e le setlolo se ka tšeptjoang ka ho fetisisa sesoleng, sefofaneng, indastering ea nyutlelie le libakeng tse ling tse tsoetseng pele ka lilemo tse mashome.Kajeno, perfluoropolyether e sebelisoa haholo indastering ea lik'hemik'hale, lisebelisoa tsa elektronike, lisebelisoa tsa motlakase, mechine, indasteri ea nyutlelie le sefofane.
