Umehluko phakathi kwe-ETFE ne- PTFE materials
I-ETFE (ethylene-tetrafluoroethylene copolymer) kanye PTFE (i-polytetrafluoroethylene) ama-fluoroplastic amabili asebenza kahle kakhulu, ahluke kakhulu ngesakhiwo samakhemikhali, izakhiwo zemishini, izici zokucubungula, kanye nezicelo. I-ETFE, ngenkathi sinakekela PTFEUkumelana namakhemikhali okuhle kakhulu, kuthuthukisa kakhulu amandla emishini nokusebenza kokucubungula, kodwa ukumelana nezinga lokushisa kuphansi kancane. PTFE, ngakolunye uhlangothi, idume ngokumelana namazinga okushisa aphakeme kakhulu kanye nokuzinza kwamakhemikhali, kodwa kunzima kakhulu ukuyicubungula. Okulandelayo ukuqhathanisa okuningiliziwe kwakho kokubili ngemibono eminingi.
Isakhiwo Samakhemikhali Nezakhiwo Eziyisisekelo
- PTFE: I-Polymerized kusuka ku-tetrafluoroethylene monomers, isakhiwo sayo samangqamuzana simbozwe ngokuphelele ama-athomu e-fluorine. Inobucwebe obuphezulu kanye nokungangenisi kwamakhemikhali aqine ngokwedlulele, okuyenza ibe nesihloko esithi “King of Plastics.”
- I-ETFE: I-copolymer eshintshanayo ye-ethylene ne-tetrafluoroethylene. Ukwethulwa kwamayunithi e-ethylene ochungechungeni lwamangqamuzana kunciphisa okuqukethwe kwe-fluorine, ngaleyo ndlela kuthuthukise ukuqina nokucutshungulwa, kepha ukumelana kwayo kwamakhemikhali kungaphansi kancane PTFE.
Mechanical Properties Ukuqhathanisa
- Amandla Nokuqina: I-ETFE inamandla aqinile afinyelela ku-50 MPa, aphindwe kabili PTFE, kanye nobude obungu-100% -300%, okubonisa ukumelana nomthelela omuhle kakhulu; PTFE, ngakolunye uhlangothi, ayinamandla kodwa inokumelana nezinyembezi eziphakeme.
- I-Coefficient of Friction: Zombili zinama-coefficients aphansi kakhulu wokungqubuzana, kodwa PTFE inikeza ukumelana nokugqoka okuphezulu, kuyilapho i-ETFE ifaneleka kakhulu izingxenye zesakhiwo ezidinga ukuqina okuphezulu.
Icubungula ukusebenza
- I-ETFE: Iyacutshungulwa (isb, i-extrusion, ukubumba umjovo), enezinga lokushisa eliphansi lokubumba (240-270℃), ilungele ukukhiqiza izimo eziyinkimbinkimbi.
- PTFE: Indawo yokuncibilika ephezulu (327℃) kanye ne-viscosity ephezulu kakhulu yokuncibilika, okwenza kukwazi ukuncibilika; ngokuvamile kusetshenzwa kusetshenziswa izinqubo ze-sintering noma zokucindezela, okuholela ezindlekweni eziphezulu zokucubungula.
