Ngenxa yezindlela ezahlukene ze-polymerization ze-ptfe, kukhona izinto zokumisa (i-polymerization yokumiswa) kanye nezinto zokuhlakazeka (i-polymerization yokusabalalisa), okuyi-suspension ptfe, i-disperse ptfe, izindlela zokucubungula zezinto ezimbili nazo zihlukile.

Izinto ezimisiwe (i-polytetrafluoroethylene emisiwe)
Indlela yayo eyinhloko yokwakha indlela yokucindezela ukufa, okungukuthi, impushana emhlophe ngaphandle kwesithasiselo esincane, bese ifa ukucindezela ukwakha, i-sintering ngaphezu kwezinga lokushisa elincibilikayo, bese ngokusebenzisa ukucubungula okufanelekile kwemishini ibe yimikhiqizo, imikhiqizo emele ipuleti, ibha, ishubhu. , ifilimu izigaba ezine.
Impahla yokusabalalisa (ptfe)
I-PTFE impushana ecolekile elungiselelwe indlela ye-dispersion polymerization ngokuvamile ibizwa ngokuthi “i-dispersion”.Ngenxa yezakhiwo ze-fibrotic zale powder ecolekileyo, ikakhulukazi emazingeni okushisa angaphezu kuka-20℃, kunconywa ukugcina, ukuthutha kanye nokuxuba impahla ku-5 ~ 10 ℃ .Indlela yokwenza yalolu hlobo lwempahla ukusebenzisa i-ejenti eyisizayo (imvamisa i-petroleum ether noma uphethiloli) kanye nempushana ngemva kokuxuba endaweni engu-24℃ noma ngaphezulu cishe amahora angama-24 (qedela ukuguqulwa kwesigaba sekristalu) bese kwakheka, i-piston extrusion forming, drying, burning.Le ndlela yokucubungula iyaziwa ngokuthi i-paste extrusion, eyaziwa nangokuthi i-push.
Ngenxa yokuhlakazwa kosayizi wezinhlayiyana zempushana, ihlukaniswe yaba amamaki ambalwa okucaciswa, ukucaciswa okuhlukene kunezici ezihlukene zokucindezelwa kwesilinganiso.Isilinganiso sokucindezela esingaphansi kuka-100, ngokuvamile esisetshenziselwa ukukhiqiza impahla eluhlaza kanye ne-microporous tape;Isilinganiso sokucindezela esincane esingaphansi kuka-500, esetshenziselwa ukukhiqiza imikhiqizo yokucaciswa okuphakathi nendawo enkulu; i-500 ~ 2000 iyisilinganiso sokucindezelwa okuphakathi.2000 ~ 4400 impahla yesilinganiso sokucindezelwa okuphezulu, le nto ifaneleka ukukhiqizwa komugqa omncane wodonga oluncane, ingaqhubeka ubude obukhulu kanye nokukhiqizwa okuphezulu okusebenzayo.
Indlela yokuhlonza: umehluko omkhulu ubukhulu bezinhlayiyana ezimbili azifani.Impahla yokumiswa iqinile, impahla yokusabalalisa ilungile.
