Polyvinylidene fluoride orpolyvinylidene difluoride (PVDF) o se semi-crystalline thermoplastic fluoropolymer.E faigofie ona liusuavai ma e mafai ona fau i ni vaega e ala i tui ma fa'apipi'iina.E tuʻufaʻatasia le malosi faʻainisinia maualuga ma le faʻaogaina lelei.PVDFe masani ona fa'afaigaluegaina i meafaigāluega vaila'au e pei o pamu, valve, paipa, paipa ma mea fa'apipi'i.O lona fua fa'atatau o le (C2H2F2)n.PVDF o se palasitika faʻapitoa e faʻaaogaina i talosaga e manaʻomia ai le mama maualuga, faʻapea foʻi ma le tetee atu i solvents, acids ma hydrocarbons.PVDF e maualalo le mamafa 1.78 g/cm3 pe a faatusatusa i isi fluoropolymers, pei polytetrafluoroethylene.
E maua i le tulaga o paipa oloa, pepa, paipa, ata tifaga, ipu ma se insulator mo uaea premium.E mafai ona tui, faʻapipiʻiina pe faʻafefe ma e masani ona faʻaaogaina i vailaʻau, semiconductor, falemaʻi ma puipuiga, faʻapea foʻi mamaa lithium-ion.E maua foi e pei o sefeso'ota'i foam sela tapuni, fa'aaogaina fa'ateleina i va'alele ma aerospace talosaga, ma o se filament lomitusi 3D ese.E mafai fo'i ona fa'aoga i feso'ota'iga faifaipea ma mea'ai, aua e fa'amalieina le FDA ma e le o'ona i lalo ifo o lona vevela fa'aleagaina.
I tausaga talu ai nei, ua tele le fiafia na faʻaalia i le polymer Polyvinylidene Fluoride (PVDF).O le tului na maua ona o lo'o fa'aalia ai mea sili ona malosi piezoelectric pe a fa'atusatusa i so'o se isi polymer fa'apisinisi.O le polymer e fa'aaogaina lautele i fa'aoga fa'atekonolosi e pei o masini fa'agasologa o vaila'au, eletise ma mea fa'aeletonika, fa'apitoa ma le malosi fa'atatau.Ae, o le a le mea e avea ai le PVDF ma palasitika maualuga i le tele o vaega?Faitau atili e iloa atili.
PVDF (PVF2 poʻo le Polyvinylidene fluoride poʻo le polyvinylidene difluoride) o se semi-crystalline, maualuga le mama thermoplastic fluoropolymer.Faatasi ai ma le vevela o auaunaga e oʻo atu i le 150°C, PVDF faʻaalia lelei tuʻufaʻatasiga o meatotino e pei o:
- Fa'ateteleina fa'ama'i
- Malosi fa'ainisinia maualuga
- Piezoelectric ma pyroelectric meatotino
- Faʻapea foʻi ma le lelei o gaioiga
O lona mana'omia tele o le insolubility ma le eletise e mafua mai i le polarity o le sui o CH2 ma le CF2 vaega i luga o le filifili polymer.
O le PVDF e faigofie ona liusuavai ma e mafai ona gaosia i ni vaega e ala i tui ma faʻamalosi faʻamalosi.O le i'uga, e masani ona fa'aaogaina i masini fa'agaoioiga e pei o pamu, valve, paipa, paipa ma mea fa'apipi'i;sensors ma actuators ma isi.
O lo'o i ai le tele o fa'aoga fa'aeletoroni, aemaise lava e pei o mea fa'apipi'i mo le uaea fa'apitoa e fa'aaogaina i masini leo ma vitiō ma faiga fa'ailo.O le maualalo o le mumu ma le asu o le PVDF ose mea taua i nei talosaga.
O le PVDF o loʻo mauaina le taliaina e avea o se fusi mo cathodes ma anodes i maʻa lithium-ion, ma avea ma se vavae o le maa i le lithium-ion polymer system.
O fa'aoga fou a le PVDF o lo'o aofia ai le suau'u cell membranes, ma vaega mo va'alele totonu ma masini masini ofisa
Faʻafetai i lona tuʻufaʻatasiga sili ona lelei o meatotino ma le faʻagasologa, PVDF ua avea ma voluma sili ona tele o fluoropolymers pe a uma le PTFE.
O lo'o avanoa fa'apisinisi le PVDF i le tele o fua fa'afefete fa'afefete ma fa'atasi ai ma fa'aopoopoga eseese e fa'aleleia atili ai le gaosiga po'o le fa'aaogaina o meatotino.
O tatou masini toe fa'aaogaina palasitika e mafai ona faʻaogaina le faʻailoga faʻapitoa ma le paelo e faʻagasolo ai ma toe faʻaaogaina le PVDF. O le Screw matou te faʻaaogaina le uʻamea C267 ma faʻaaogaina e le paelo le uʻamea Ni.Ole faiga toe fa'aaogā ma pelletizing ole a fa'aogaina lepelletizing manoa e fa'agaoioia mea.
Fa'afetai
