PTFE na PFA Ikinyugunyugu Valve Ibikoresho Bitandukanye

(Incamake ibisobanuro) PTFE EPDM ikinyugunyugu kicaye

Teflon PTFE izwi kandi nka polytetrafluoroethylene.Teflon PFA izwi kandi nka soluble polytetrafluoroethylene. Kugura valve byinshi ntibisobanutse neza niyihe nziza yo kurwanya ruswa kubibinyugunyugu ukoresheje PTFE na PFA? Ni izihe nyungu n'ibibi bya buri? Itandukaniro mukurwanya ubushyuhe, ninde uhendutse?
Bitandukanye muri kamere
1.PFA: copolymer yumubare muto wa perfluoropropyl perfluorovinyl ether na polytetrafluoroethylene.2.PTFE: uruganda rwa polymer rwakozwe na polymerisation ya tetrafluoroethylene.

. Ubushyuhe bwo kubumba ntiburenga 475 ° C, ifumbire yashyutswe kugeza kuri 150 - 200 ° C, kandi sisitemu yo gusuka ntishobora kurwanya ibintu bitemba.

PTFE Ibiranga

(1) Kurwanya ubushyuhe bwinshi: birebire - gukoresha ubushyuhe 200 ~ 260 ℃;

(2) Kurwanya ubushyuhe buke: byoroshye kuri - 100 ℃;

(3) Kurwanya ruswa: irwanya aqua regia hamwe nudukoko twose kama;

(4) Kurwanya ikirere: ubuzima bwiza bwo gusaza bwa plastiki;
(5) Amavuta menshi: hamwe na coefficient ntoya yo guterana (0.04) muri plastiki;
.
Itandukaniro rinini ni uko PFA yoroshye gutunganya kandi ihenze kuruta PTFE, ariko mubikorwa PTFE ifite irwanya ruswa nziza kandi nayo irwanya ubushyuhe bwinshi.
Ikoranabuhanga rya Sansheng Fluorine ni uruganda rukora inganda kandi rutanga ibicuruzwa byikinyugunyugu mu Bushinwa, rukabyara ibinyugunyugu bya PTFE na PFAined, niba ufite ikibazo kijyanye n’ikinyugunyugu cyangwa ugasaba ibisobanuro, nyamuneka twandikire. + 8615067244404
