PTFE imayimira PolyTetraFluoroEthylene, omwe ndi mawu oti polima (CF2)n.
Polytetrafluoroethylene (PTFE) ndi membala wa thermoplastic wa banja la fluoropolymer la mapulasitiki ndipo ali ndi coefficient yocheperako yakukangana, zoteteza kwambiri.
High-Quality Bray PTFE+EPDM Butterfly Valve Liner - DN50-DN600
M'malo ovuta a mafakitale a mafakitale ndi ntchito, kukhulupirika ndi kudalirika kwa zigawo zikuluzikulu. A Sansheng fluorine amayambitsa chikhomo cha kusindikiza ndi ntche ya a Bray Ptferffer. Opangidwa mwanzeru kuti atumikire cholinga chachiwiri, izi zimagwirizana ndi mankhwala osayerekezereka kwa ptfe (polytetrafluoro solylene) yokhala ndi zotupa za epdm (ethylene ma promer). Chizindikiro changwiro chomwe sichimangokhala pampando wa valavu yomwe sikuti amangopereka malonjezo koma amasulabe mazero a Zero kudutsa mawonekedwe osiyanasiyana kuchokera kwa diameter ya DN50 mpaka DN600.
Kukhumudwitsa mikhalidwe ya namwali ya namwali PTF, ambiri amadziwikanso kuti Tefnn, valavu yathu imayima osagwirizana ndi mavuto. Izi zimawapangitsa kukhala katundu wofunika kwambiri m'makampani omwe kuwonekera kwamankhwala ndi tsiku lililonse. Ptfe, ndi kapangidwe kake kochulukitsa kwa polymer, amaonetsetsa kuti valavu iliyonse imapereka chotchinga chopanda malire chotsutsana ndi madzimadzi, mpweya, komanso mankhwala ovuta kwambiri. Kuphatikizika kwa zinthu zolimba, kuphatikizana ndi kusinthasintha kwa EPDM, kumawonjezera zomwe akutsatira pakusintha kwa kutentha ndi zovuta zamakina, kuonetsetsa kukhala ndi moyo komanso kudalirika. A Sansheng fluorine ptfe + ptfe + epdm ngulume yolima ndi yoposa imodzi. Ndi chipangano chabwino kwambiri, chomwe chimapangidwa kuti chikwaniritse zolimba zamakono zamakono. Kuchokera ku mafuta a petrochemical ku chakudya ndi malo okhala zakumwa, izi zikuwonetsetsa kuti kugwira ntchito mwaluso, chitetezo, komanso luso. Kudzipereka kwathu kwa abwino ndipo luso latsopano kuwonetsetsa kuti malonda aliwonse amapangidwa mosavuta, amapereka magwiridwe osasankhidwa komanso mtendere wamalingaliro kwa makasitomala athu. Landirani tsogolo la ukadaulo wa Valve lero ndi kuona kusiyana ndi njira zapamwamba za Mafuta a Sanheorine.

Virgin PTFE (Polytetrafluoroethylene)
PTFE (Teflon) ndi polima yopangidwa ndi fluorocarbon ndipo nthawi zambiri imakhala yosamva mapulasitiki onse, pomwe imasungabe zinthu zabwino kwambiri zamafuta ndi magetsi. PTFE ilinso ndi coefficient yotsika ya kukangana kotero ndi yabwino kwa ambiri otsika torque ntchito.
Izi sizoyipa komanso zovomerezeka ndi a FDA pazakudya. Ngakhale kuti makina a PTFE ndi otsika, poyerekeza ndi mapulasitiki ena opangidwa ndi injini, katundu wake amakhalabe wothandiza pa kutentha kwakukulu.
Kutentha: - 38 ° C '23 ° C.

Ubwino:
PTFE imayimira PolyTetraFluoroEthylene, omwe ndi mawu oti polima (CF2)n.
Polytetrafluoroethylene (PTFE) ndi membala wa thermoplastic wa banja la fluoropolymer la mapulasitiki ndipo ali ndi coefficient yocheperako yakukangana, zoteteza kwambiri.
PTFE ndi mankhwala olowera kuzinthu zambiri. Itha kupiriranso ntchito zotentha kwambiri ndipo imadziwika bwino chifukwa cha anti-ndodo.
Kusankha Mphete yolondola nthawi zambiri imakhala chisankho chovuta kwambiri Vavu ya Mpira Kusankha. Kuti tithandizire makasitomala athu panthawi imeneyi, ndife ofunitsitsa kupereka zidziwitso pa pempho la makasitomala.
PTFE valavu mipando opangidwa ndi US chimagwiritsidwa ntchito mu nsalu, siteshoni mphamvu, petrochemical, Kutentha ndi firiji, mankhwala, shipbuilding, zitsulo, makampani kuwala, kuteteza chilengedwe, Paper Makampani, Shuga Makampani, Woponderezedwa Air ndi zina.
Kuchita kwa mankhwala: kukana kutentha kwakukulu, kukana kwa asidi wabwino ndi alkali ndi kukana mafuta; yokhala ndi mphamvu zobwereranso bwino, zolimba komanso zolimba popanda kutayikira.
Kukhumudwitsa mikhalidwe ya namwali ya namwali PTF, ambiri amadziwikanso kuti Tefnn, valavu yathu imayima osagwirizana ndi mavuto. Izi zimawapangitsa kukhala katundu wofunika kwambiri m'makampani omwe kuwonekera kwamankhwala ndi tsiku lililonse. Ptfe, ndi kapangidwe kake kochulukitsa kwa polymer, amaonetsetsa kuti valavu iliyonse imapereka chotchinga chopanda malire chotsutsana ndi madzimadzi, mpweya, komanso mankhwala ovuta kwambiri. Kuphatikizika kwa zinthu zolimba, kuphatikizana ndi kusinthasintha kwa EPDM, kumawonjezera zomwe akutsatira pakusintha kwa kutentha ndi zovuta zamakina, kuonetsetsa kukhala ndi moyo komanso kudalirika. A Sansheng fluorine ptfe + ptfe + epdm ngulume yolima ndi yoposa imodzi. Ndi chipangano chabwino kwambiri, chomwe chimapangidwa kuti chikwaniritse zolimba zamakono zamakono. Kuchokera ku mafuta a petrochemical ku chakudya ndi malo okhala zakumwa, izi zikuwonetsetsa kuti kugwira ntchito mwaluso, chitetezo, komanso luso. Kudzipereka kwathu kwa abwino ndipo luso latsopano kuwonetsetsa kuti malonda aliwonse amapangidwa mosavuta, amapereka magwiridwe osasankhidwa komanso mtendere wamalingaliro kwa makasitomala athu.
