PTFE ndi PFA Butterfly Valve Zosiyanasiyana Zosiyanasiyana

(Mafotokozedwe achidule)PTFE EPDM mpando wagulugufe wa gulugufe

Teflon PTFE imadziwikanso kuti polytetrafluoroethylene.Teflon PFA imadziwikanso kuti soluble polytetrafluoroethylene.Kugula kwa ma valve ambiri sikumveka bwino komwe kuli bwino kukana dzimbiri kwa mavavu agulugufe pogwiritsa ntchito PTFE ndi PFA? Kodi ubwino ndi kuipa kwa aliyense ndi chiyani? Kusiyana kwa kukana kutentha, komwe kuli kotchipa?
Zosiyana ndi chilengedwe
1.PFA: copolymer yaing'ono ya perfluoropropyl perfluorovinyl ether ndi polytetrafluoroethylene.2.PTFE: gulu la polima lopangidwa ndi polymerization ya tetrafluoroethylene.
Makhalidwe osiyanasiyana
Makhalidwe a PFA
(1) Crystal zinthu, otsika chinyezi absorption.It akhoza kukonzedwa mu mankhwala ndi thermoplastic processing njira.
([2) Kuipa, kosavuta kuwola komanso mpweya wowononga umapangidwa pakawola. Kutentha kwa kutentha sikudutsa 475 ° C, nkhungu imatenthedwa kufika 150 - 200 ° C, ndipo dongosolo lothira silikhala ndi kukana pang'ono kwa zinthu zomwe zikuyenda.
(3 trasucent pelles, ijection molding and extrusion molding. Kutentha kwa nkhungu ndi 350-400C, 475℃ ndi pamwamba ndizosavuta kupangitsa utoto kapena matuza. Samalani zovuta kugwetsa.

(4) Chifukwa dzimbiri zotsatira zosungunula zitsulo, yaitali-kupanga amafuna chrome plating pa nkhungu.PTFE makhalidwe

Makhalidwe a PTFE

(1) High kutentha kukana: yaitali-nthawi ntchito kutentha 200 ~ 260 ℃;

(2) Kutsika kwa kutentha: kufewa pa -100 ℃;

(3) Kukana kwa dzimbiri: kugonjetsedwa ndi aqua regia ndi zosungunulira zonse za organic;

(4) Kukana kwanyengo: moyo wabwino kwambiri wokalamba wa mapulasitiki;
(5)Kupaka mafuta kwambiri: kocheperako pang'ono (0.04) pakati pa mapulasitiki;
(6) Yopanda - yomata: Imakhala ndi chipwirikiti chaching'ono kwambiri pakati pa zida zolimba popanda kumamatira kuzinthu zilizonse. Mwachidule
Kusiyanitsa kwakukulu ndikuti PFA ndiyosavuta kuyikonza komanso yokwera mtengo kuposa PTFE, koma pochita PTFE imakhala yabwino kwambiri yolimbana ndi dzimbiri komanso imalimbana ndi kutentha kwambiri.
Sansheng Fluorine Plastics Technology ndi opanga mafakitale komanso ogulitsa ma valve agulugufe ku China, omwe amapanga PTFE ndi ma valve agulugufe a PFAlined, ngati muli ndi mafunso okhudza ma valve agulugufe kapena kupempha mawu oti mawu, chonde omasuka kulankhula nafe.+8615067244404
