PVC VS PTFE

Ptfe ke Eng?

Polytetrafluoroethylene (PTFE) ke fluoropolymer ea maiketsetso ea tetrafluoroethylene mme ke PFAS e nang le lits'ebetso tse ngata.PTFE's bohlokoa lik'hemik'hale, mocheso, mongobo, 'me ho hanyetsa motlakase e etsa hore e be sesebediswa se loketseng neng kapa neng ha lihlahisoa, lisebelisoa le likarolo li hloka ho tšoarella le ho ts'epahala esita le lits'ebetsong tse thata ka ho fetisisa.Ka holim'a sena, PTFE e ithorisa ka ho tšoarella ha mocheso o tlaase le ho hanyetsa mollo o etsang hore e be khetho e ntle bakeng sa lethathamo le ntseng le hōla la lihlahisoa, likaroloana le lisebelisoa.

PVC ke eng?

PVCke polymer ea maiketsetso ea boraro lefatšeng ka bophara e hlahisoang ka bongata (ka mor'a polyethylene le polypropylene). Ho etsoa lithane tse ka bang limilione tse 40 tsa PVC selemo le selemo.

PVC e tla ka mokhoa o thata (ka linako tse ling e khutsufatsoa e le RPVC) le mefuta e bonolo.PVC e thata e sebelisoa kahong ea liphaephe, mamati le lifensetere.E boetse e sebelisoa ho etsa libotlolo tsa polasetiki, ho paka, le likarete tsa banka kapa tsa botho.Ho eketsa li-plasticizers ho etsa hore PVC e be bonolo hape e tenyetsehe haholoanyane.E sebelisoa ho kenya lipeipi tsa metsi, lithapo tsa methapo ea motlakase, fatše, lipontšo, lirekoto tsa keramafono, lihlahisoa tse nang le moea o fokang, le linthong tse ling tsa rabara.Ka k'hothone kapa line, e sebelisoa ho hlahisa seile.
