Polyvinylidene fluoride ori-polyvinylidene difluoride (PVDF) yi-semi-crystalline thermoplastic fluoropolymer.Iyakwazi ukunyibilika ngokulula kwaye inokwenziwa ukuba ibe ngamalungu ngenaliti kunye noxinzelelo lokubumba.Idibanisa amandla omatshini aphezulu kunye nokusebenza kakuhle.PVDFidla ngokusetyenziswa kwizixhobo zokulungisa iikhemikhali ezifana neempompo, iivalvu, imibhobho, iityhubhu kunye nezinto zokufakelwa.Ifomula yayo yeekhemikhali yi (C2H2F2)n.I-PVDF yiplastiki ekhethekileyo esetyenziswa kwizicelo ezifuna ubunyulu obuphezulu, kunye nokumelana nezinyibilikisi, iiasidi kunye neehydrocarbons.I-PVDF inoxinano oluphantsi 1.78 g/cm3 xa kuthelekiswa nezinye i-fluoropolymers, njenge-polytetrafluoroethylene.
Ifumaneka ngendlela yeemveliso zombhobho, iphepha, iityhubhu, iifilimu, ipleyiti kunye ne-insulator yocingo lweprimiyamu.Inokuthi itofwe, ibunjwe okanye idityaniswe kwaye isetyenziswa ngokuqhelekileyo kwimichiza, i-semiconductor, amashishini ezonyango kunye nokukhusela, kunye nakumashishini.iibhetri ze-lithium-ion.Ikwafumaneka njenge-aidityanisiwe i-foam yeseli evaliweyo, isetyenziswa ngokwandayo kuphapho kunye nezicelo ze-aerospace, kwaye njenge-3D yomshicileli we-filament engaqhelekanga.Ingasetyenziselwa ukudibanisa ngokuphindaphindiweyo kunye neemveliso zokutya, njengoko i-FDA-ithobela kwaye ayinayo inetyhefu ngaphantsi kobushushu bayo bokuthotywa.
Kwiminyaka yakutshanje, kukho umdla omkhulu obonakalisiweyo kwipolymer Polyvinylidene Fluoride (PVDF).Umdla ewufumeneyo kuba ubonisa iipropathi ezinamandla zepiezoelectric xa kuthelekiswa nayo nayiphi na enye ipholima yorhwebo.I-polymer isetyenziswa ngokubanzi kwizicelo zetekhnoloji ephezulu ezifana nezixhobo zenkqubo yeekhemikhali, umbane kunye ne-elektroniki, ubungcali kunye nezicelo ezinxulumene namandla.Kodwa, yintoni eyenza iPVDF ibe yiplastiki yokusebenza okuphezulu kumacandelo amaninzi?Funda ukuze ukwazi ngakumbi.
I-PVDF (i-PVF2 okanye i-Polyvinylidene fluoride okanye i-polyvinylidene difluoride) yi-semi-crystalline, i-high purity thermoplastic fluoropolymer.Ngobushushu benkonzo ukuya kuthi ga kwi-150°C, iPVDF ibonisa indibaniselwano elungileyo yeepropati ezifana nezi:
- Ukumelana neekhemikhali ezikhethekileyo
- Amandla omatshini aphezulu
- Iimpawu zePiezoelectric kunye nepyroelectric
- Kanye nokuqhubekeka kakuhle
I-insolubility enqwenelekayo kakhulu kunye neempawu zombane ziphuma kwi-polarity yokutshintshiselana kwamaqela e-CH2 kunye ne-CF2 kwi-polymer chain.
I-PVDF iyanyibilika ngokulula kwaye inokwenziwa ukuba ibe ngamalungu ngenaliti kunye nokubunjwa ngokucinezela.Ngenxa yoko, isetyenziswa ngokuqhelekileyo kwizixhobo zokulungisa iikhemikhali ezifana neepompo, iivalve, iipayipi, iibhubhu kunye nezixhobo;abenzi boluvo kunye nee-activators njl.
Inezicelo ezininzi ze-elektroniki, ngakumbi njengemathiriyeli yejacket ye-plenum-rated cable esetyenziswa kwizixhobo zelizwi kunye nevidiyo kunye neenkqubo ze-alam.Ukusasazeka komlilo ophantsi kunye nokuveliswa komsi kwePVDF yeyona asethi iphambili kwezi zicelo.
I-PVDF ifumana ukwamkelwa njenge-binder ye-cathodes kunye ne-anode kwiibhetri ze-lithium-ion, kwaye njengesahluli sebhetri kwiinkqubo ze-polymer ze-lithium-ion.
Usetyenziso olusakhulayo lwePVDF lubandakanya iimbumba zeeseli zamafutha, kunye namacandelo angaphakathi kwenqwelomoya kunye nezixhobo ezizenzekelayo zeofisi.
Ndiyabulela kwindibaniselwano egqwesileyo yeepropati kunye nokuqhubekeka, i-PVDF ibe ngowona mthamo mkhulu we-fluoropolymers emva kwe-PTFE.
I-PVDF ifumaneka kurhwebo kuluhlu olubanzi lwamazinga okuncibilika okunyibilikayo kunye nezongezo ezahlukeneyo zokuphucula ukusetyenzwa okanye ukuphelisa iipropati zokusetyenziswa.
Yethu umatshini wokurisayikilisha weplastiki inokusebenzisa isikrufu esikhethekileyo kunye nomphanda ukusetyenzwa kunye nokuphinda kusetyenziswe i-PVDF.I-Screw sithatha i-alloy ye-C267 kunye ne-barrel ithatha i-Ni ialloy.Inkqubo yokurisayikilisha kunye ne-pelletizing iya kusebenzisa ii-strand pelletizing ukucubungula imathiriyeli.
