Menene kayan PVDF?
Polyvinylidene Fluoride (PVDF) abu ne mai girma da aka yi amfani da shi sosai a cikin masana'antun sinadarai da masana'antu, kuma ana fifita shi don kyakkyawan juriyar sinadarai, kayan lantarki da ƙarfin injina. A cikin wannan labarin, za mu bincika dalla-dalla menene PVDF, kaddarorin sa, aikace-aikace da tsarin samarwa don taimaka muku fahimtar fa'idodin wannan kayan.
Na farko, ainihin halayen PVDF
PVDF ne Semi-crystalline thermoplastic fluoropolymer, yawanci polymerized daga vinylidene fluoride (VDF) monomer. Saboda girman electronegativity na atom na fluorine da ƙarfin haɗin CF, PVDF yana nuna kaddarorin masu zuwa:

Juriya na sinadarai: PVDF yana da matukar juriya ga yawancin acid, alkalis, salts da sauran kaushi, wanda ke sa ya tsaya tsayin daka da juriya ga lalata a cikin masana'antar sinadarai kan lokaci.

Ƙarfin Injini: PVDF yana da kyakkyawan ƙarfi mai ƙarfi da juriya mai tasiri, yana ba ta damar kiyaye amincin tsarin sa a cikin yanayi mara kyau.

Lantarki Properties: Saboda da low dielectric akai da kuma high insulating Properties, PVDF ne yadu amfani a lantarki da lantarki filayen, musamman a matsayin insulating Layer abu ga wayoyi da igiyoyi.

Zaman lafiyar zafi: PVDF yana da kwanciyar hankali mai kyau kuma ana iya amfani dashi a cikin yanayin zafi da yawa, kuma yawanci yana iya kula da kayan jikinsa a cikin kewayon zafin jiki na -40°C zuwa 150°C.

Na biyu, tsarin samar da PVDF
Samar da PVDF galibi ana samun su ta hanyar polymerisation na radical, yawanci ta hanyar polymerisation bayani ko kuma dakatar da polymerisation. A cikin tsari na polymerisation, VDF monomers ana yin polymerised zuwa PVDF polymer a ƙarƙashin takamaiman yanayin dauki. Bayan haka, ta hanyar jerin matakai na bayan-jiyya, ciki har da tsarkakewa, extrusion da granulation, samuwar ƙarshe na samfuran PVDF tare da takamaiman kaddarorin jiki.
Na uku, manyan wuraren aikace-aikacen PVDF
An yi amfani da PVDF sosai a cikin masana'antu da yawa saboda kyakkyawan aikin sa:

Masana'antar sinadarai: Ana amfani da PVDF sosai wajen kera kwantenan sinadarai iri-iri, bututu da bawuloli, musamman a lokutan da suka shafi sinadarai masu lalata.

Masana'antar gine-gine: Ana amfani da PVDF wajen kera kayan kwalliya masu inganci, irin su fluorocarbon coatings, waɗanda ake amfani da su don kare bangon gine-gine na waje, kuma suna iya kula da kyawawan gine-gine na dogon lokaci saboda halayen UV da tsufa.

Masana'antar lantarki da lantarki: Ana amfani da PVDF ko'ina a cikin samar da igiyoyi, masu haɗawa da diaphragms na baturi na lithium saboda kyakkyawan rufin lantarki da juriya na zafi.

Masana'antar kula da ruwa: Ana amfani da kayan membrane na PVDF a fagen jiyya na ruwa, musamman a cikin ultrafiltration da nanofiltration membranes, waɗanda aka fi so don babban juriya na sinadarai da ingantaccen tacewa.

Na hudu, hasashen kasuwa da kalubale na PVDF
Tare da haɓakar haɓaka masana'antu da haɓaka buƙatun kayan aiki mai mahimmanci, kasuwar PVDF tana haɓaka da sauri.Haɓaka farashin samarwa da rikitarwa na tsarin samarwa na PVDF yana sa farashin kasuwarsa ya fi tsada. Aikace-aikacen PVDF kuma yana fuskantar wasu ƙalubale saboda al'amuran muhalli masu alaƙa da fluoride. Sabili da haka, inganta tsarin samarwa da rage tasirin muhalli na PVDF zai zama mabuɗin ci gaba na gaba.
Takaitawa
Menene kayan PVDF? Ta hanyar binciken da ke sama, zamu iya ganin cewa PVDF babban kayan aiki ne na fluoropolymer tare da fa'idodin aikace-aikace iri-iri. Kyakkyawan juriya na sinadarai, ƙarfin injina, kayan lantarki da kwanciyar hankali na zafi sun sa ya taka muhimmiyar rawa a fagage da yawa. Tare da haɓaka buƙatun kare muhalli, samarwa da aikace-aikacen PVDF kuma za su fuskanci sabbin ƙalubale da dama. Fahimtar da sarrafa kaddarorin da aikace-aikacen PVDF na iya ba da tallafi mai mahimmanci don ƙirƙira da haɓaka masana'antu masu alaƙa.
