I-Polyvinylidene fluoride ori-polyvinylidene difluoride (PVDF) iyi-semi-crystalline thermoplastic fluoropolymer.Ikwazi ukuncibilika kalula futhi ingenziwa izingxenye ngomjovo kanye nokubunjwa kokucindezelwa.Ihlanganisa amandla aphezulu emishini nokucutshungulwa okuhle.I-PVDFngokuvamile isetshenziswa emishinini yokucubungula amakhemikhali njengamaphampu, amavalvu, amapayipi, amashubhu kanye nezinto ezifakwayo.Ifomula yayo yamakhemikhali ithi (C2H2F2)n.I-PVDF iyipulasitiki ekhethekile esetshenziswa ezinhlelweni ezidinga ukuhlanzeka okuphezulu kakhulu, kanye nokumelana nezinyibilikisi, ama-asidi nama-hydrocarbon.I-PVDF inokuminyana okuphansi okungu-1.78 g/cm3 uma kuqhathaniswa namanye ama-fluoropolymer, njenge-polytetrafluoroethylene.
Itholakala ngemikhiqizo yamapayipi, ishidi, ishubhu, amafilimu, ipuleti kanye nesivikeli sezintambo ze-premium.Ingajovwa, ibunjwe noma ishiselwe futhi ivamise ukusetshenziswa embonini yamakhemikhali, esemiconductor, yezokwelapha nezokuvikela, kanye nasezimbonini.amabhethri e-lithium-ion.Iyatholakala futhi njenge-akuxhumene igwebu lamaseli avaliwe, esetshenziswa kakhulu ezinhlelweni zezindiza kanye ne-aerospace, nanjenge-filament yephrinta ye-3D exotic.Ingasetshenziswa futhi ekuthintaneni okuphindaphindiwe nemikhiqizo yokudla, njengoba ihambisana ne-FDA futhi ayinabo ubuthi ngaphansi kwezinga lokushisa lokuwohloka kwayo.
Eminyakeni yamuva nje, kube nentshisekelo enkulu evezwe ku-polymer Polyvinylidene Fluoride (PVDF).Intshisekelo eyitholile ngoba ibonisa izakhiwo ze-piezoelectric eziqine kakhulu uma kuqhathaniswa nanoma iyiphi enye i-polymer yokuhweba.I-polymer isetshenziswa kabanzi ezinhlelweni eziphakeme zobuchwepheshe ezifana nemishini yenqubo yamakhemikhali, ugesi kanye ne-electronics, okukhethekile kanye nezicelo ezihlobene namandla.Kodwa, yini eyenza i-PVDF ibe ipulasitiki yokusebenza okuphezulu emikhakheni eminingana?Funda ukuze wazi okwengeziwe.
I-PVDF (i-PVF2 noma i-Polyvinylidene fluoride noma i-polyvinylidene difluoride) iyi-semi-crystalline, i-thermoplastic fluoropolymer emsulwa ehlanzekile.Ngamazinga okushisa esevisi afika ku-150°C, i-PVDF ibonisa inhlanganisela enhle yezakhiwo ezifana nalezi:
- Ukumelana namakhemikhali okukhethekile
- Amandla aphezulu emishini
- Izakhiwo ze-Piezoelectric kanye ne-pyroelectric
- Kanye nokucutshungulwa okuhle
Ukungancibiliki kwayo okufiseleka kakhulu kanye nezakhiwo zikagesi ziwumphumela wokuhlukahlukana kwamaqembu e-CH2 ne-CF2 ochungechungeni lwe-polymer.
I-PVDF ikwazi ukuncibilika kalula futhi ingakhiwa ibe izingxenye ngomjovo nokubunjwa kokucindezelwa.Ngenxa yalokho, kuvame ukusetshenziswa emishinini yokucubungula amakhemikhali njengamaphampu, ama-valve, amapayipi, amashubhu kanye nokufakwa;izinzwa nama-actuator njll.
Inezinhlelo zokusebenza eziningi ze-elekthronikhi, ikakhulukazi njengezinto zokufaka amajakhethi zekhebula elikalwe nge-plenum elisetshenziswa kumishini yezwi neyevidiyo nezinhlelo ze-alamu.Ukusabalala kwelangabi eliphansi kanye nokukhiqizwa kwentuthu kwe-PVDF kuyimpahla eyinhloko kulezi zinhlelo zokusebenza.
I-PVDF ithola ukwamukelwa njengesibopho sama-cathodes nama-anode kumabhethri e-lithium-ion, nanjengesehlukanisi sebhethri ezinhlelweni ze-polymer ze-lithium-ion.
Izinhlelo ezisafufusa ze-PVDF zifaka ulwelwesi lwamaseli kaphethiloli, kanye nezingxenye zangaphakathi zendiza kanye nemishini yokushintshashintsha yasehhovisi.
Ngenxa yokuhlanganiswa kwayo okuhle kakhulu kwezakhiwo nokuqhubekela phambili, i-PVDF isibe ivolumu enkulu yama-fluoropolymers ngemuva kwe-PTFE.
I-PVDF iyatholakala ngokwentengiso ngenani elibanzi lamazinga okuncibilika kanye nezithasiselo ezahlukahlukene zokuthuthukisa ukucubungula noma ukuqeda izakhiwo zokusetshenziswa.
Eyethu umshini wokugaywa kabusha wepulasitiki singasebenzisa isikulufu esikhethekile kanye nomgqomo ukucubungula nokuphinda kusetshenziswe i-PVDF.Isikulufa sithatha ingxubevange ye-C267 futhi umgqomo wamukela ingxubevange ye-Ni.Uhlelo lokugaywa kabusha kanye ne-pelletizing luzosebenzisai-strand pelletizing ukucubungula impahla.
Ngiyanibingelela,
