Teflon tubes ke fluoroplastic tubes e entsoeng ka thepa ea polytetrafluoroethylene ka ho kopanya, ho etsa embryo, ho hatella ho bata, ho sintering le ho pholile.
Li-tubes tsa Teflon li na le thepa e ntle haholo:
① Coefficient e tlase ea khohlano;
②Corrosion resistance: acid e matla le alkali resistance, mme hoo e ka bang lik'hemik'hale tsohle ha li sebetse (ka mocheso o phahameng le fluorine le alkali metal reaction) , li ka hanela "Aqua regia" corrosion;
③Ho itlhoekisa: ho thata ho khomarela polytetrafluoroethylene;
④Ha e chese;
⑤Ho hanyetsa mocheso o phahameng: PTFE teflon thepa ea mocheso e ka fihla -70 ° C ~ 260 ° C;
⑥Ho hanyetsa ho phahameng: Teflon tube e nang le khanyetso e phahameng, ts'ebetso e ntle ea ho kenya letsoho;
⑦ Anti-botsofali: Ts'ebetso ea Teflon Tube e khahlanong le botsofali e ntle haholo, bophelo bo bolelele ba ts'ebeletso.
Botsofali ba hose ea PTFE bo ke ke ba hlokomolohuoa, ts'ebetso ea lihlahisoa e tla fokotseha ka mor'a botsofali, kahoo, tlhahiso ea morao, re tlameha ho kenya ts'ebetsong letoto la mehato ea ho thibela.
Theipi e khomarelang ea lihlahisoa tsa Teflon tube e kenngoe ka mokhoa oa ho phekola sebabole. Ho hanyetsa mocheso oa vulcanizate ea eona ho ka ntlafatsoa ka ho fokotsa kapa ho qoba tšebeliso ea sebabole sa motheo, se ka fokotsang kapa sa felisa polysulfide cross-linking mme haholo-holo se hlahisa sebabole se le seng kapa disulfide cross-linking.
Tšebeliso ea peroxide e hlokahala ho finyella mocheso o motle oa ho hanyetsa, kaha ho phekola ka peroxide ho hlahisa li-crosslink tsa carbon-carbon tse nang le thermostable. Tlhokomelo e khethehileng e lokela ho lefshoa ho li-additives tse ling ha u sebelisa peroxide. Ka mohlala, khetho ea li-antioxidants e hloka ho ba thata haholoanyane, kaha bongata ba bona bo kena-kenana le peroxide, vulcanization.
Ho phaella moo, ha u sebelisa peroxide, fokotsa palo ea li-fillers tsa acid ho thibela li-peroxide cations hore li se ke tsa senyeha, e leng se etsang hore ho be le vulcanization e tlaase ea hose e phahameng ea khatello (ka mokhoa oa ho thatafalloa ka tlaase, modulus e tlaase le e phahameng ea compression set) . Ho eketsa metsoako ea motheo, joalo ka zinc oxide kapa magnesium oxide, moo ho khonehang, hangata ho ka ntlafatsa bokhoni ba ho tšela peroxide. E ntse e na le phello ea oli ea parafine ho molemo, batla ho qoba ho sebelisa oli e nkhang hamonate ea hydrocarbon le solvent.
