I-PTFE, FEP kanye ne-PFA ama-fluoroplastic aziwa kakhulu futhi ajwayelekile.Kodwa uyini ngempela umehluko wabo?Thola ukuthi kungani ama-fluoropolymers eyizinto ezihlukile kangaka, futhi iyiphi i-fluoroplastic efaneleka kakhulu kuhlelo lwakho lokusebenza.
Izakhiwo eziyingqayizivele ze-fluoroplastics
Ama-fluoropolymers ajabulela izakhiwo ezimbalwa eziyingqayizivele ezizenza zifanelekele ukusetshenziswa kwezokwelapha, ezezimoto, izicelo zikagesi nezasekhaya, phakathi kokunye.
I-Fluoroplastics inezindawo ezilandelayo:
1.Amazinga okushisa aphezulu kakhulu okusebenza
2.Isici esinganamatheli
3.Low friction surface
I-4.Ukumelana okuphezulu kakhulu kumakhemikhali nama-solvents
5.Ukumelana nogesi okuphakeme kakhulu
Ama-fluoroplastic ahlukene ajabulela umehluko ocashile, okuhlanganisa amazinga okushisa ahlukahlukene okusebenza, futhi afanele ukusetshenziswa okuhlukile.Uma kukhethwe kahle, ama-fluoropolymers angaletha izinzuzo ezinhle zentengo nokusebenza.
Izinzuzo ze-PTFE
I-PTFE, noma i-Polytetrafluoroethylene, ingumkhulu wawo wonke ama-fluoroplastics.Kutholwe usosayensi u-Roy J. Plunkett ngo-1938, i-PTFE iyi-fluoropolymer engavamile kakhulu futhi ibonisa ukusebenza okuhle kakhulu mayelana nezinga lokushisa, ukumelana namakhemikhali kanye nezakhiwo ezinganamathele.
Ngaphezu kokujabulela izakhiwo eziyingqayizivele ze-fluoroplastics, i-PTFE iyazihlukanisa ngokuba nezinzuzo ezilandelayo:
1.Intengo engcono kakhulu : isilinganiso sokusebenza
2.Izinga lokushisa eliqhubekayo lokusebenza elingu-+260°C - Leli izinga lokushisa eliphakeme kakhulu elisebenza kunoma iyiphi i-fluoroplastic
3.Ukumelana cishe nawo wonke amakhemikhali
4.Ukungagxili kakhulu (ngisho nesigcilikisha singashelela ku-PTFE)
5.Umbala okhanyayo
Ububi obuyinhloko be-PTFE ukuthi empeleni ayincibiliki lapho ishiswa ngakho-ke kunzima ukuyicubungula.Kudingeka amasu angajwayelekile kakhulu ukubumba, ukukhipha kanye nokushisela le fluoropolymer.
Ngenxa yezakhiwo zayo ezihlukile, i-PTFE ilungele ukusetshenziswa ekufakweni kukagesi kanye nokuvikelwa kwezingxenye ze-elekthronikhi.
Singumkhiqizi ochwepheshe weptfe ipayipi, uma unemibuzo, ungaxhumana nathi!
Izinzuzo ze-FEP
I-FEP, noma i-Fluoroethylenepropylene, inguqulo ye-PTFE encibilikayo.I-FEP inezici ezifanayo kakhulu ne-PTFE, kodwa inezinga lokushisa eliphezulu eliphansi eliphansi lika-+200°C.Kodwa-ke, i-FEP ingacutshungulwa kalula futhi ingashiselwa kalula futhi ibunjwe kabusha ibe amaphrofayili ayinkimbinkimbi.
Kanye nokuba nezinto eziyingqayizivele ze-fluoroplastics, i-FEP ijabulela lezi zinzuzo:
1. Amandla okushisela kanye nokubumba kabusha
2.Amazinga okushisa okusebenza oku- -200°C kuya ku-+200°C - i-FEP ihlala iguquguquka emazingeni okushisa e-cryogenic
3.Ingqikithi yokumelana namakhemikhali kanye ne-UV
4.I-Bio-iyahambisana
5. Umbala ocacile
Ngenxa yalezi zinzuzo, ukuncipha kokushisa kwe-FEP kunezinga lokushisa eliphansi lokushwabana futhi kungashwabana ngokuphephile kuzinto ezizwelayo kuzinga lokushisa ngaphandle kokwesaba ukudala umonakalo.Ngenxa yalokho, i-FEP ilungele ukuhlanganisa izingxenye zikagesi ezibucayi nezinsimbi.
Izinzuzo ze-PFA
I-PFA, noma i-Perfluoralkoxy, inguqulo yezinga lokushisa eliphezulu le-FEP.I-PFA inezici ezifanayo ne-FEP kodwa ingasetshenziswa emazingeni okushisa asebenzayo afika ku-+260°C kuyilapho isala ingancibilika, ngenxa ye-viscosity encibilikayo ephansi kune-PTFE.
Ngaphezu kokujabulela izakhiwo ezihlukile zama-fluoropolymers, i-PFA iyazihlukanisa ngokuba nezinzuzo ezilandelayo:
Izinga lokushisa eliqhubekayo lokusebenza lika +260°C - Leli izinga lokushisa eliphakeme kakhulu lokusebenza kunoma iyiphi i-fluoroplastic
1.Ukushisela kanye nokubumba kabusha amandla
2.Good permeability ukumelana
I-3.Ukumelana namakhemikhali okuhle kakhulu, ngisho namazinga okushisa aphakeme
4.I-Bio-iyahambisana
5.Amamaki okuhlanzeka aphezulu atholakalayo
6.Sula umbala
Ububi obukhulu be-PFA ukuthi ibiza kakhulu kune-PTFE ne-FEP.
I-PFA ilungele izinhlelo zokusebenza ezidinga izinga eliphezulu lokuhlanzeka, ukumelana namakhemikhali okuhle kakhulu kanye nezinga lokushisa eliphezulu lokusebenza.Le fluoroplastic isetshenziswa kakhulu kumashubhu ezokwelapha, izishintshisi zokushisa, obhasikidi abangama-semi-conductor, amaphampu nokufakwa, kanye nama-valve liners.
Lapha kuBesteflonsingochwepheshe ekuletheni izixazululo ezintsha ze-fluoropolymer zezinhlelo zakho zokusebenza zobuchwepheshe.Thola okwengeziwe mayelana yethuImikhiqizo ye-Fluoroplastic.
