Njirimara PCTFE

PCTFE bụ polymer semirystalline nwere yinye polymer helical na kristal pseudohexagonal.Uto kristal bụ nke na-eme ka ọ nwee ụdọ apịaji.Nnukwu nha nke chlorine na-egbochi recrystallization mgbe agbazechara n'oge nhazi.Resin a nwere ezigbo ihe na okpomọkụ cryogenic metụtara plastik n'ozuzu ya, n'agbanyeghị na ha dị ala karịa ndị fluoropolymers ndị ọzọ ma e wezụga PVDF.

PCTFE nwere ihe mgbochi pụrụiche yana nguzogide kemịkalụ mara mma.A na-awakpo ya site na ọtụtụ ihe mgbaze organic.

PCTFE nwere nkwụsi ike dị ala ma na-eweda ya ala mgbe ọ ruru ebe mgbaze ya, na-achọ nlekọta pụrụ iche n'oge nhazi.

Njirimara ETFE

PVDF na equimolar ETFE bụ isomers mana nke ikpeazụ nwere ebe mgbaze dị elu yana ọnwụ dielectric dị ala karịa nke mbụ.ETFE na-atụgharị n'ime sel otu kwenyere na ọ bụ orthorhombic ma ọ bụ monoclinic.Nkwekọrịta molekụla nke ETFE bụ zigzag gbatịrị agbatị.A na-agbaze polymer a na ụfọdụ esters na-esi esi n'elu 230 C, si otú a na-enye ohere ikpebi ịdị arọ molekul (nkezi arọ) site na ịgbasa ọkụ.ETFE nwere ọtụtụ ntụgharị, izu ike alfa na 110 C (na-agbanwe na 135 C na crystallinity dị elu), beta na 25 C, na ntụrụndụ gamma na 120 C.

ETFE terpolymers nwere ezigbo ihe eji arụ ọrụ gụnyere tensile na ịkpụ-site na nguzogide na mgbaka ala karịa perfluoropolymers.ETFE na-eguzogide ọgwụ karịa radieshon karịa perfluoropolymers (jiri obi umeala na-emetụta ruo 20 Mrad) na enwere ike ịfefe ya site na radieshon dị ka beam electron.A na-eji crosslinking na-eme ka nkwụsi ike nke mkpuchi waya ETFE sie ike.

ETFE nwere dielectric mgbe niile nke 2.6e3.4 na ihe nkwụsị nke 0.0006e0.010 ka ugboro na-abawanye site na 102 ruo 1010 Hz.

Ndị terpolymer ETFE na-eguzogide nrụgide nrụgide na ọgụ kemịkalụ site na ọtụtụ ogige.Acids oxidizing siri ike, acid sulfonic na-esi esi ike, na ntọala organic (amines) na-awakpo ETFE na kemịkalụ ọ bụla na-emetụta PTFE, PFA, na FEP.

Njirimara ECTFE

ECTFE bụ semirystalline (50e60%) ma gbazee na 240 C. Ọ nwere ntụrụndụ alfa na 140 C, beta na 90 C, na ntụrụndụ gamma na 65 C. Conformation nke ECTFE bụ zigzag agbatị nke ethylene na CTFE ọzọ.Otu cell nke kristal ECTFE bụ hexagonal.

Yiri ETFE, ECTFE terpolymers (otu termonomers) nwere mma n'ibu na abrasion na radieshon iguzogide karịa PTFE na ndị ọzọ perfluoropolymers.

Dielectric mgbe niile nke ECTFE bụ 2.5e2.6, na onwe ya na okpomọkụ na ugboro.Ihe nchụsa bụ 0.02 ma buru ibu karịa nke ETFE.

ECTFE na-eguzogide ọtụtụ kemịkalụ ma ewezuga pola na-ekpo ọkụ na ihe mgbaze chlorinated.Ọ naghị emesi ike mgbawa mgbaze na ihe mgbaze ọ bụla.ECTFE nwere ihe mgbochi ka mma na SO2, Cl2, HCl, na mmiri karịa FEP na PVDF.
