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.
Premium EPDM+PTFE Compound Butterfly Valve Seat - Sansheng
Sansheng fluorine pulasitiki imayamba kuwunika boma lathu - la - art - Amapangidwira kasitomala wozindikira yemwe amafunikira kudalirika komanso kukhala ndi moyo wautali, mipando yathu ya valavu imapangidwa kuti ipereke mwayi wapadera komanso kugwiritsa ntchito miyezo yatsopano, kukonza miyezo yatsopano m'makampani.
Pamtima pazinthu zathu ndi kuphatikizika kwa EPDM (Ethylene Proplene allne monomer) mphira ndi PTFEFLOFLOFEELEELE), amadziwikanso kuti Teflonyleeneene. Kuphatikiza kwa synergy uwu kumabweretsa zinthu zabwino kwambiri za zinthu zonsezi: kulimba mtima ndi kutukula kwa Epdm ndi mankhwala osayerekezeka a PTF. Zotsatira zake ndi mpando wa valavu yomwe siyimangothana ndi kutentha kwambiri komanso zinthu zimatsimikizira ziphuphu za zero, ndikuwonetsetsa kuti zitsamba za mafakitale osiyanasiyana, kuchokera kwa DN500 mpaka DN600. Kudzipereka kwathu kumawonekera pakugwiritsa ntchito namwali potche, kuonetsetsa kuti mpando uliwonse umadzitamandira kwambiri komanso kukhala ndi moyo wautali. Kukhazikika kwa mankhwala kwa PTF kumatanthauza mipando yathu ya gulugufe sikunasinthe pafupifupi mankhwala onse a mafakitale, ma acid, ndikuyipitsa, kuti akhale ndi mtima wosagawanika kwambiri. Kuphatikizidwa ndi kuchuluka komanso kuchuluka kwa nyengo ya Epdm, mipando yathu ya valavu yathu ikulonjeza moyo wowonjezera ndikuchepetsa ndalama zochepetsera, zikuwonetsetsa kuti ndi ntchito yopanda pake komanso ntchito yabwino. Khulupirirani Sansheng fluorine plastic ya valavu yanu ikufunika ndikukumana ndi kusiyana komwe kumapangitsa kuti mainjiniya akhale oyenda bwino.

Zero Leakage PTFE Valve Seat Butterfly Valve Parts DN50 - Chithunzi cha DN600
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 ndizosaipitsa ndikuvomerezedwa 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.
Mtundu: woyera

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, asidi wabwino ndi alkali kukana ndi kukana mafuta; yokhala ndi mphamvu zobwereranso bwino, zolimba komanso zolimba popanda kutsika.
Pamtima pazinthu zathu ndi kuphatikizika kwa EPDM (Ethylene Proplene allne monomer) mphira ndi PTFEFLOFLOFEELEELE), amadziwikanso kuti Teflonyleeneene. Kuphatikiza kwa synergy uwu kumabweretsa zinthu zabwino kwambiri za zinthu zonsezi: kulimba mtima ndi kutukula kwa Epdm ndi mankhwala osayerekezeka a PTF. Zotsatira zake ndi mpando wa valavu yomwe siyimangothana ndi kutentha kwambiri komanso zinthu zimatsimikizira ziphuphu za zero, ndikuwonetsetsa kuti zitsamba za mafakitale osiyanasiyana, kuchokera kwa DN500 mpaka DN600. Kudzipereka kwathu kumawonekera pakugwiritsa ntchito namwali potche, kuonetsetsa kuti mpando uliwonse umadzitamandira kwambiri komanso kukhala ndi moyo wautali. Kukhazikika kwa mankhwala kwa PTF kumatanthauza mipando yathu ya gulugufe sikunasinthe pafupifupi mankhwala onse a mafakitale, ma acid, ndikuyipitsa, kuti akhale ndi mtima wosagawanika kwambiri. Kuphatikizidwa ndi kuchuluka komanso kuchuluka kwa nyengo ya Epdm, mipando yathu ya valavu yathu ikulonjeza moyo wowonjezera ndikuchepetsa ndalama zochepetsera, zikuwonetsetsa kuti ndi ntchito yopanda pake komanso ntchito yabwino.
