Polyvinylidene fluoride orpolyvinylidene difluoride (PVDF) bụ fluoropolymer nke ọkara kristal.A na-agbaze ya ngwa ngwa ma nwee ike ịmepụta ya n'ime akụkụ site na ntụtụ na ịkpụzi mkpakọ.Ọ na-ejikọta elu n'ibu ike na ezi processability.PVDFA na-arụkarị ọrụ na akụrụngwa nhazi kemịkalụ dị ka nfuli, valves, ọkpọkọ, ọkpọkọ na akwa akwa.Usoro kemịkal ya bụ (C2H2F2) n.PVDF bụ rọba ọpụrụiche ejiri na ngwa chọrọ ịdị ọcha kachasị elu, yana iguzogide ihe mgbaze, acids na hydrocarbons.PVDF nwere obere njupụta 1.78 g/cm3 ma e jiri ya tụnyere fluoropolymers ndị ọzọ, dị ka polytetrafluoroethylene.
Ọ dị n'ụdị ngwaahịa ọkpọkọ, mpempe akwụkwọ, tubing, fim, efere na ihe mkpuchi maka waya adịchaghị.Enwere ike ịgbanye ya, ịkpụzi ma ọ bụ welded ma na-ejikarị ya na kemịkalụ, semiconductor, ahụike na ụlọ ọrụ nchekwa, yanabatrị lithium-ion.Ọ dịkwa ka across-njikọ ụfụfụ mechiri emechi, ejiri na-abawanye na ngwa ụgbọ elu na ngwa ikuku, yana dị ka filament ngwa nbipute 3D dị egwu.Enwere ike iji ya na kọntaktị ugboro ugboro na ngwaahịa nri, n'ihi na ọ na-akwado FDA na adịghị egbu egbu n'okpuru ọnọdụ okpomọkụ ya.
N'afọ ndị na-adịbeghị anya, enweela mmasị dị ukwuu egosipụtara na polymer Polyvinylidene Fluoride (PVDF).Mmasị ọ nwetara n'ihi na ọ na-egosipụta akụrụngwa piezoelectric kachasị ike ma e jiri ya tụnyere polymer azụmahịa ọ bụla.A na-eji polymer eme ihe na ngwa teknụzụ dị elu dị ka akụrụngwa usoro kemịkalụ, eletriki na elektrọnik, ọpụrụiche na ngwa metụtara ike.Mana, gịnị na-eme PVDF ka ọ bụrụ plastik arụmọrụ dị elu n'ọtụtụ ngalaba?Gụkwuo ka ịmatakwu.
PVDF (PVF2 ma ọ bụ Polyvinylidene fluoride ma ọ bụ polyvinylidene difluoride) bụ ọkara kristal, fluoropolymer thermoplastic dị ọcha.Site na okpomọkụ ọrụ ruo 150ºC, PVDF na-egosiputa ezigbo ngwakọta nke akụrụngwa dịka:
- Nguzogide kemịkalụ pụrụiche
- Ike igwe dị elu
- Piezoelectric na pyroelectric Njirimara
- Yana ezi usoro nhazi
Ọdịmma ya na-achọsi ike nke ukwuu na akụrụngwa eletrik sitere na polarity nke ndị ọzọ CH2 na CF2 na yinye polymer.
PVDF na-agbaze ngwa ngwa ma nwee ike mepụta ya n'ime akụkụ site na ịgbanye na ịkpụzi mkpakọ.N'ihi ya, a na-ejikarị ya arụ ọrụ na-arụ ọrụ na-emepụta kemịkalụ dị ka nfuli, valves, ọkpọkọ, tubes na ntinye;sensọ na actuators wdg.
Ọ nwere ọtụtụ ngwa eletrọnịkị, ọkachasị dị ka ihe mkpuchi maka eriri plenum nke ejiri olu na ngwaọrụ vidiyo na sistemụ mkpu.Mgbasa ọkụ dị ala na ọgbọ anwụrụ ọkụ nke PVDF bụ ihe bara uru na ngwa ndị a.
PVDF na-enweta nnabata dị ka ihe nkedo maka cathodes na anodes na batrị lithium-ion, yana dị ka ihe nkesa batrị na sistemụ lithium-ion polymer.
Ngwa PVDF na-apụta gụnyere akpụkpọ mmanụ mmanụ, yana akụrụngwa maka ime ụgbọ elu na akụrụngwa akpaaka ụlọ ọrụ
N'ihi nchikota ya magburu onwe ya nke ihe onwunwe na nhazi usoro, PVDF aghọwo nnukwu olu nke fluoropolymers mgbe PTFE gasịrị.
PVDF dị n'ahịa n'ọtụtụ ọkwa agbaze agbaze yana yana mgbakwunye dị iche iche iji kwalite njikwa ma ọ bụ njedebe ojiji.
Anyị igwe eji emeghari igwe nwere ike iji mkpọsa na gbọmgbọm pụrụ iche iji hazie na megharịa PVDF. The Screw anyị na-ewere C267 alloy na gbọmgbọm nakweere Ni alloy.Usoro ihe eji emegharị ihe na pelletizing ga-ejieriri pelletizing iji hazie ihe.
