The monomer ea PTFE ke tetrafluoroethylene (TFE), 'me ntlha ea eona e belang ke -76.3 degrees Celsius.E phatloha haholo ha e le teng ha oksijene e le teng 'me e ka bapisoa le phofo ea sethunya.Ka hona, tlhahiso ea eona, polokelo le tšebeliso ea indasteri e hloka tšireletso e thata haholo, tlhahiso e boetse e hloka ho laoloa, e leng e 'ngoe ea mehloli e meholo ea litšenyehelo tsa PTFE.TFE hangata e sebelisa mahala radical suspension polymerization indastering, ho sebelisa persulfate e le initiator, mocheso karabelo e ka ba pakeng tsa 10-110 likhato Celsius, mokhoa ona o ka fumana phahameng haholo limolek'hule boima PTFE (esita le e ka ba fetang limilione tse 10), ha ho na ketane e bonahalang. phetiso e etsahala.
Kaha ntlha ea ho qhibiliha ea PTFE e phahame haholo, e haufi le mocheso oa ho bola, 'me boima ba eona ba molek'hule ha bo nyane, ho batla ho le thata ho finyella tekanyo e nepahetseng ea ho qhibiliha ha metsi ka ho itšetleha feela ka ho futhumatsa joaloka li-polymers tse tloaelehileng tsa thermoplastic.Theipi ea Teflon kapa Teflon tube e entsoe joang?Tabeng ea ho bōptjoa, phofo ea PTFE e atisa ho tšeloa ka har'a hlobo, ebe e futhumala le ho hatelloa ho sinter phofo.Haeba extrusion e hlokahala, metsoako ea hydrocarbon e hloka ho kenngoa ho PTFE ho thusa ho susumetsa le ho phalla.Palo ea metsoako ena ea hydrocarbon e tlameha ho laoloa ka har'a mefuta e itseng, ho seng joalo ho bonolo ho baka khatello e feteletseng ea extrusion kapa bofokoli ba sehlahisoa se felileng.Ka mor'a foromo e lakatsehang, metsoako ea hydrocarbon e tlosoa ka ho futhumala butle, ebe e futhumatsoa le ho silafatsoa ho etsa sehlahisoa sa ho qetela.
Tšebeliso ea PTFE
E 'ngoe ea litšebeliso tse ka sehloohong tsa PTFE ke ho roala.Ho tloha ka pane e nyenyane e se nang thupa lapeng ho ea leboteng le ka ntle la cube ea metsi, u ka utloa phello ea boselamose ea ho roala hona.Lisebelisoa tse ling ke tepi ea ho tiisa, tšireletso ea ka ntle ea terata, moqomo o ka hare oa moqomo, likarolo tsa mochine, labware, joalo-joalo Haeba u hloka thepa e lokelang ho sebelisoa maemong a thata, joale e nahane, e ka 'na ea e-ba le liphello tse sa lebelloang.
