Pekala, y\u00fcksek s\u0131cakl\u0131k boru malzemelerinin ayr\u0131nt\u0131lar\u0131na girmeden \u00f6nce durumu netle\u015ftirelim.

Zaten PVDF Nedir?<\/h3>\n\n\n\n

PVDF veya biraz daha teknik olmak gerekirse poliviniliden flor\u00fcr, 60'larda mukavemet gerektiren borular ve filmler i\u00e7in pop\u00fcler bir se\u00e7enek olarak ortaya \u00e7\u0131kt\u0131. Onu sert ve g\u00fc\u00e7l\u00fc k\u0131lan yar\u0131 kristal bir yap\u0131s\u0131 vard\u0131r; yakla\u015f\u0131k 50 MPa'l\u0131k \u00e7ekme mukavemetini d\u00fc\u015f\u00fcn\u00fcn, bu da b\u00fck\u00fclmeden mekanik stresle ba\u015fa \u00e7\u0131kmak i\u00e7in sa\u011flam bir de\u011ferdir.

Ancak can al\u0131c\u0131 nokta \u015fu: En verimli oldu\u011fu aral\u0131k 150\u00b0C civar\u0131ndaki s\u00fcrekli kullan\u0131md\u0131r.

\u015eimdi, PFA'ya\u2014perfloroalkoksi\u2014ge\u00e7elim.

Kimyasal olarak, PVDF'nin daha haval\u0131, daha diren\u00e7li kuzeni gibidir; ayn\u0131 flor kalkan\u0131na sahiptir ancak safl\u0131k ve ak\u0131\u015f i\u00e7in geli\u015ftirilmi\u015ftir.

Bak\u0131n\u0131z, anl\u0131yorum; ortam\u0131n\u0131z 140\u00b0C'nin alt\u0131ndaysa PVDF'ye ba\u011fl\u0131 kalmak g\u00fcvenli hissettirir.

\u0130lk olarak, termal kararl\u0131l\u0131k. PVDF 150\u00b0C'nin \u00fczerinde depolimerize olmaya ba\u015flar ve t\u00fcm sisteminizi a\u015f\u0131nd\u0131rabilecek hidroflorik asit a\u00e7\u0131\u011fa \u00e7\u0131kar\u0131r.

Sonra esneklik fakt\u00f6r\u00fc var. Y\u00fcksek s\u0131cakl\u0131klar genle\u015fme ve b\u00fcz\u00fclme anlam\u0131na gelir; malzemenizin k\u0131r\u0131lmadan b\u00fck\u00fclmesi gerekir. PVDF'nin sertli\u011fi so\u011fukta harikad\u0131r ancak s\u0131cakta k\u0131r\u0131lganla\u015farak mikro \u00e7atlaklara yol a\u00e7ar. PFA, kopma uzamas\u0131 300%'nin \u00fczerinde olan daha elastik bir perfluoroalkoksi zincirine sahiptir. \u015eunu hayal edin: 240\u00b0C'de buhar i\u00e7eren bir g\u0131da i\u015fleme hatt\u0131.

Ya safl\u0131k? Yar\u0131 iletken veya t\u0131bbi sekt\u00f6rdeyseniz, ekstrakte edilebilir maddeler \u00e7ok \u00f6nemlidir. PVDF'nin milyonda bir seviyelerine kar\u015f\u0131l\u0131k PFA, milyarda bir seviyelerine sahiptir.
