Guryaha Polymer - PCTFE & ETFE & Guryaha ECTFE

PCTFE waa polymer-ka semicrystalline oo leh silsilad polymer helical iyo crystal pseudohexagonal ah.PVDF iyo Equimolar ETFE waa isomers laakiin kan dambe wuxuu leeyahay dhibic dhalaalaysa sare iyo khasaaro ka hooseeya dielectric marka loo eego kuwii hore. Simi la mid ah ETFE, ECTFE terpolymers (la mid ah termonomers) waxay leeyihiin caabbinta farsamo iyo abrasion iyo shucaaca ka fiican PTFE iyo perfluoropolymers kale.

Guryaha PCTFE

PCTFE waa polymer-ka semicrystalline oo leh silsilad polymer helical iyo crystal pseudohexagonal ah.Koritaanka kristal waa spherulitic wuxuuna ka kooban yahay silsilado laalaaban.Cabbirka weyn ee koloriinku wuxuu xannibaa dib-u-kicinta ka dib dhalaalidda inta lagu jiro habaynta.Xabagtani waxay leedahay sifooyin wanaagsan heerkulka cryogenic marka loo eego caagagga guud ahaan, in kasta oo ay ka hooseeyaan fluoropolymers-ka kale marka laga reebo PVDF.

PCTFE waxay leedahay sifooyin caqabado gaar ah iyo iska caabin kiimiko oo heersare ah.Waxaa lagu soo weeraray tiro ka mid ah dareerayaasha organic.

PCTFE waxay leedahay xasilloonida kulaylka oo hooseeya waxayna hoos u dhigtaa markay gaarto barta dhalaalkeeda, waxay u baahan tahay daryeel gaar ah inta lagu jiro habaynta.

Guryaha ETFE

PVDF iyo equimolar ETFE waa isomers laakiin kan dambe wuxuu leeyahay meel dhalaalaysa oo sare iyo khasaare ka hooseeya kii hore.ETFE waxay u kireysataa unugyo la rumeysan yahay inay yihiin orthorhombic ama monoclinic.Qaabka molecular ee ETFE waa zigzag fidsan.Polymer-kaan waxa lagu milmaa qaar ka mid ah ester-ka karkarinta ee ka sarreeya 230 C, sidaas darteed u oggolaanaya go'aaminta miisaanka molecular (celceliska-miisaanka) kala firdhinta iftiinka.ETFE waxay leedahay kala-guuro dhowr ah, nasashada alfa oo ah 110 C (waxay u beddeshaa 135 C at crystallinity sare), beta at 25 C, iyo nasashada gamma ee 120 C.

Eterpolymers ETFE waxay leeyihiin sifooyin farsamo oo wanaagsan oo ay ku jiraan adkaysi iyo iska caabin la gooyey iyo gurguurta hoose marka loo eego perfluoropolymers.ETFE way uga adkeysi badan tahay shucaaca marka loo eego kuwa perfluoropolymers (si fudud u saameeyay ilaa 20 Mrad) waxaana isku xidhi kara shucaaca sida iftiinka elektarooniga ah.Crosslinking waxaa loo isticmaalaa in lagu xoojiyo iska caabbinta goynta ee dahaarka siliga ETFE.

ETFE waxay leedahay dielectric joogto ah oo ah 2.6e3.4 iyo factor dissipation of 0.0006e0.010 sida soo noqnoqda kordho 102 ilaa 1010 Hz.

Eterpolymers-yada ETFE waxay u adkeysanayaan dildilaaca walbahaarka iyo weerarka kiimikada ee xeryahooda intooda badan.Asiidh oksaydhing oo xooggan, asiidh sulfonic ah oo karkarinaysa, iyo saldhigyada organic (amines) waxay weeraraan ETFE iyo kiimiko kasta oo saameeya PTFE, PFA, iyo FEP.

Guryaha ECTFE

ECTFE waa semirystalline (50e60%) waxayna dhalaalisaa 240 C. Waxay leedahay nasinta alfa at 140 C, beta at 90 C, iyo nasashada gamma at 65 C. Conformation of ECTFE waa zigzag fidsan kaas oo ethylene iyo CTFE beddelanayaan.Unugga unugga crystal ECTFE waa laba geesood.

Si la mid ah ETFE, ECTFE terpolymers (isku mid termonomers) waxay leeyihiin iska caabin farsamo iyo xoqid iyo shucaac ka wanaagsan PTFE iyo perfluoropolymers kale.

Joogtada dielectric ee ECTFE waa 2.5e2.6, oo ka madax banaan heerkulka iyo inta jeer.Qodobada kala daadsanaantu waa 0.02 oo aad uga weyn kuwa ETFE.

ECTFE waxay u adkaysataa inta badan kiimikooyinka marka laga reebo dabaylaha kulul iyo dareerayaasha koloriin leh.Ma cadda in dildilaacku ku milmo wax kasta oo dareere ah.ECTFE waxay leedahay siyaalo ka ilaalinaya SO2, Cl2, HCl, iyo biyaha marka loo eego FEP iyo PVDF.
