I-PTFE, i-FEP kanye ne-PFA yizona zinhlobo ze-fluoroplastics ezaziwa kakhulu futhi ezivame kakhulu. Kodwa yini ngempela umehluko wazo? Thola ukuthi kungani ama-fluoropolymers eyizici ezihlukile kangaka, nokuthi iyiphi i-fluoroplastic efaneleka kakhulu ekusetshenzisweni kwakho.
Izakhiwo eziyingqayizivele ze-fluoroplastics
Ama-fluoropolymers anezakhiwo eziningana ezihlukile ezenza afaneleke ukusetshenziswa kwezokwelapha, izimoto, ugesi kanye nezicelo zasekhaya, phakathi kwezinye.
Ama-fluoroplastic analezi zakhiwo ezilandelayo:
1. Amazinga okushisa aphezulu kakhulu okusebenza
2. Isici esinganamatheli
3.Umphezulu wokungqubuzana ophansi
4. Ukumelana okuphezulu kakhulu namakhemikhali kanye nezinyibilikisi
5. Ukumelana kukagesi okuphezulu kakhulu
Ama-fluoroplastic ahlukene anokwehluka okuncane, okuhlanganisa amazinga okushisa asebenzayo ahlukahlukene, futhi afanele ukusetshenziswa okuhlukile. Uma ekhethwe kahle, ama-fluoropolymer angaletha izinzuzo zentengo ezinhle kanye nokusebenza kahle.
Izinzuzo ze-PTFE
I-PTFE, noma i-Polytetrafluoroethylene, ingumkhulu wazo zonke i-fluoroplastics. Yatholwa usosayensi uRoy J. Plunkett ngo-1938, i-PTFE iyi-fluoropolymer engavamile kakhulu futhi ibonisa ukusebenza okuhle kakhulu ngokwezinga lokushisa, ukumelana namakhemikhali kanye nezakhiwo ezinganamatheli.
Ngaphezu kokujabulela izakhiwo ezihlukile ze-fluoroplastics, i-PTFE iyazihlukanisa ngokuba nezinzuzo ezilandelayo:
1. Intengo engcono kakhulu: isilinganiso sokusebenza
2. Izinga lokushisa lokusebenza eliqhubekayo elingu-+260°C - Leli izinga lokushisa lokusebenza eliphakeme kakhulu kunoma iyiphi i-fluoroplastic
3. Ukumelana cishe nawo wonke amakhemikhali
4. Ayinamatheli kakhulu (ngisho ne-gecko ingashelela ku-PTFE)
5. Umbala okhanyayo
Ububi obukhulu be-PTFE ukuthi ayincibiliki ngempela uma ishiswa ngakho-ke kunzima ukuyicubungula. Kudingeka amasu angajwayelekile kakhulu ukuze kubunjwe, kukhishwe futhi kushiselwe le fluoropolymer.
Ngenxa yezakhiwo zayo ezihlukile, i-PTFE ilungele ukusetshenziswa ekufakweni kokushisa kagesi kanye nokuvikelwa kwezingxenye ze-elekthronikhi.
Singumkhiqizi ochwepheshe weipayipi le-ptfe， Uma unemibuzo, ungaxhumana nathi!
Izinzuzo ze-FEP
I-FEP, noma i-Fluoroethylenepropylene, inguqulo ye-PTFE encibilikayo. I-FEP inezakhiwo ezifanayo kakhulu ne-PTFE, kodwa inokushisa okuphezulu kokusebenza okuphansi okungu-+200°C. Kodwa-ke, i-FEP ingacutshungulwa kalula futhi ingashintshwa kalula futhi ibunjwe kabusha ibe amaphrofayili ayinkimbinkimbi.
Ngaphezu kokuba nezakhiwo ezihlukile ze-fluoroplastics, i-FEP ijabulela lezi zinzuzo:
1. Amandla okushisela nokulungisa kabusha
2. Amazinga okushisa okusebenza asukela ku-200°C kuya ku-+200°C - I-FEP ihlala iguquguquka emazingeni okushisa aguquguqukayo
3. Ukumelana okuphelele kwamakhemikhali kanye ne-UV
4. Iyahambisana ne-bio
5. Umbala ocacile
Ngenxa yalezi zinzuzo, ukuncipha kokushisa kwe-FEP kunokushisa okuphansi kokuncipha futhi kungancishiswa ngokuphephile phezu kwezinto ezizwela ukushisa ngaphandle kokwesaba ukubangela umonakalo. Ngenxa yalokho, i-FEP ilungele ukumboza izingxenye zikagesi ezizwela kanye nezinsimbi.
Izinzuzo ze-PFA
I-PFA, noma i-Perfluoralkoxy, inguqulo ye-FEP yokushisa okuphezulu. I-PFA inezakhiwo ezifanayo ne-FEP kodwa ingasetshenziswa emazingeni okushisa asebenzayo afinyelela ku-+260°C ngenkathi ihlala ingacutshungulwa, ngenxa ye-viscosity encibilikayo ephansi kune-PTFE.
Ngaphezu kokujabulela izakhiwo ezihlukile zama-fluoropolymers, i-PFA iyazihlukanisa ngokuba nezinzuzo ezilandelayo:
Izinga lokushisa lokusebenza eliqhubekayo elingu-+260°C - Leli izinga lokushisa lokusebenza eliphakeme kakhulu kunoma iyiphi i-fluoroplastic
1. Ukushisela kanye nokwakha kabusha amandla
2. Ukumelana okuhle kokungena
3. Ukumelana okuhle kakhulu kwamakhemikhali, ngisho noma amazinga okushisa aphezulu
4. Iyahambisana ne-bio
5. Amamaki aphezulu okuhlanzeka ayatholakala
6. Umbala ocacile
Ububi obukhulu be-PFA ukuthi ibiza kakhulu kune-PTFE kanye ne-FEP.
I-PFA ilungele ukusetshenziswa okudinga izinga eliphezulu lokuhlanzeka, ukumelana kwamakhemikhali okuhle kakhulu kanye nokushisa okuphezulu kokusebenza. Le fluoroplastic isetshenziswa kabanzi kumapayipi ezokwelapha, kuma-heat exchanger, kumabhasikidi e-semi-conductor, kumaphampu nasezintweni zokufaka, kanye nasezintweni zokufaka ama-valve.
