Gịnị bụ PCTFE (polleychlorotrifluethylene) na gịnị bụ akụrụngwa ya na ojiji?

Polychlorotrifluethyleneh (PCTFE) Aha Chinese: polychlorotrifluethyylene bekee: polychlorotrifluethylene, PCTFE. polymer nke chlorotrifluethylene. Mpempe akwụkwọ PCTFE, mkpụmkpụ maka Trifluo (F3). Enwere ike iji ọnọdụ okpomọkụ nke 213 ℃, nwere ezigbo kemịkal, enwere ike iji ya na -196 ~ 125 ℃ ruo ogologo oge Ọnụego.pctfe bụ polmel kristal, na-agbaze na 425f, njupụta nke 2.13g / cc (cc (cubic centimita). ). Idobe isi ike d85.

PCTFE bụ ihe na-ekpo ọkụ nke enwere ike hazie site na-agbaze ma ọ bụ n'ezie thermoplastic.

A na-egosipụta ihe ptcFe nke siri ike na nguzogide na-akpata ike na-eguzogide na mmiri vapor na gas, na PCTFE nwekwara njirimara dị egwu nke nguzosi ike na-eguzogide.

Isi ihe eji eme ihe nke PCTFE bu ihe mgbochi maka tankị kemịkalụ, valves, ndọpụta, wdg, wdg na arịa. N'otu oge ahụ, enwere ike iji PCTFE na akara elektrik, na-eyi ihe ga-eguzogide ya, ngwaahịa na-eguzogide ọgwụ.
