Polyvinylidene fluoride orPolyvinylidene difluoride (PVDF) wani nau'in fluoropolymer ne na Semi-crystalline thermoplastic.Yana da sauƙin narkewa kuma ana iya ƙirƙira shi cikin sassa ta hanyar allura da gyare-gyaren matsawa.Ya haɗu da babban ƙarfin inji tare da kyakkyawan tsari.PVDFyawanci ana aiki dashi a cikin kayan sarrafa sinadarai kamar famfo, bawul, bututu, bututu da kayan aiki.Tsarin sinadaransa shine (C2H2F2) n.PVDF filasta ce ta musamman da ake amfani da ita a aikace-aikacen da ke buƙatar mafi girman tsabta, da juriya ga kaushi, acid da hydrocarbons.PVDF yana da ƙarancin ƙarancin 1.78 g/cm3 idan aka kwatanta da sauran fluoropolymers, kamar polytetrafluoroethylene.
Ana samunsa ta hanyar samfuran bututu, takarda, tubing, fina-finai, faranti da insulator don waya mai ƙima.Ana iya yin allura, gyare-gyare ko welded kuma ana amfani da shi a cikin sinadarai, semiconductor, likita da masana'antun tsaro, da kumabaturi lithium-ion.Hakanan yana samuwa azaman ahaɗe-haɗe rufaffiyar kumfa, ana ƙara amfani da shi a cikin aikace-aikacen jiragen sama da sararin samaniya, kuma azaman filament na firinta na 3D mai ban mamaki.Hakanan za'a iya amfani da shi a maimaita hulɗa tare da samfuran abinci, saboda yana da yarda da FDA kuma ba mai guba ba a ƙasan yanayin zafinsa.
A cikin 'yan shekarun nan, an sami babban sha'awa da aka bayyana a cikin polymer Polyvinylidene Fluoride (PVDF).Sha'awar da ta samu saboda yana nuna mafi kyawun kaddarorin piezoelectric idan aka kwatanta da kowane polymer kasuwanci.Ana amfani da polymer ko'ina a cikin manyan aikace-aikacen fasaha kamar kayan aikin sarrafa sinadarai, lantarki da lantarki, ƙwarewa da aikace-aikacen da ke da alaƙa da makamashi.Amma, menene ya sa PVDF ya zama babban aikin filastik a sassa da yawa?Karanta don ƙarin sani.
PVDF (PVF2 ko Polyvinylidene fluoride ko polyvinylidene difluoride) wani simin-crystalline ne, babban tsaftar thermoplastic fluoropolymer.Tare da yanayin sabis har zuwa 150 ° C, PVDF yana nuna kyakkyawan haɗin kaddarorin kamar:
- Keɓaɓɓen juriya na sinadarai
- Babban ƙarfin injiniya
- Piezoelectric da pyroelectric Properties
- Kazalika mai kyau aiwatarwa
Babban kyawawa rashin solubility da kaddarorin lantarki suna haifar da polarity na madadin ƙungiyoyin CH2 da CF2 akan sarkar polymer.
PVDF yana da sauƙin narkewa kuma ana iya ƙirƙira shi cikin sassa ta hanyar allura da gyare-gyaren matsawa.Sakamakon haka, ana yawan amfani da shi a cikin kayan sarrafa sinadarai kamar famfo, bawul, bututu, bututu da kayan aiki;firikwensin da actuators da dai sauransu.
Yana da aikace-aikacen lantarki da yawa, musamman azaman kayan jaket don kebul mai ƙima da ake amfani da su a cikin na'urorin murya da na bidiyo da tsarin ƙararrawa.Ƙananan yaɗuwar harshen wuta da samar da hayaki na PVDF shine babban kadara a cikin waɗannan aikace-aikacen.
PVDF yana samun karɓuwa azaman ɗaure don cathodes da anodes a cikin batir lithium-ion, kuma azaman mai raba baturi a cikin tsarin polymer lithium-ion.
Aikace-aikace masu tasowa na PVDF sun haɗa da membranes cell man fetur, da abubuwan da aka gyara don ciki na jirgin sama da kayan aiki na ofis
Godiya ga kyakkyawar haɗuwa da kaddarorin da iya aiki, PVDF ya zama mafi girma girma na fluoropolymers bayan PTFE.
Ana samun PVDF ta kasuwanci a cikin kewayon ƙimar narke mai yawa kuma tare da ƙari daban-daban don haɓaka kayan sarrafawa ko ƙarshen amfani.
Mu Injin sake amfani da filastik na iya amfani da dunƙule da ganga na musamman don sarrafawa da sake sarrafa PVDF. Screw mun ɗauki alloy C267 kuma ganga ta ɗauki Ni gami.Tsarin sake amfani da pelletizing zai yi amfani daigiyar pelletizing don sarrafa kayan.
