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 Plastics imanyadira kuwonetsa dziko lathu-la--zaluso la EPDM+PTFE Compound Butterfly Valve Seat, kuphatikiza kolimba komanso magwiridwe antchito. Zopangidwira makasitomala ozindikira omwe amafuna kudalirika komanso kukhala ndi moyo wautali, mipando yathu ya valve imapangidwa kuti ipereke luso lapadera losindikiza komanso kukana mankhwala, kukhazikitsa miyezo yatsopano pamsika.
Pamtima pa mankhwala athu ndi kuphatikizika kwa mphira wa EPDM (Ethylene Propylene Diene Monomer) ndi PTFE (Polytetrafluoroethylene), yomwe imadziwikanso kuti Teflon. Kuphatikizika kwa synergistic kumeneku kumabweretsa zinthu zabwino kwambiri pazida zonse ziwiri: kulimba mtima komanso kukhazikika kwa EPDM komanso kukana kwamankhwala kosayerekezeka kwa PTFE. Chotsatira chake ndi mpando wa valve womwe sumangolimbana ndi kutentha kwakukulu ndi zinthu zowonongeka komanso umatsimikizira kuti zero kutayikira, zomwe zimapangitsa kukhala chisankho chabwino pa ntchito zosiyanasiyana za mafakitale, kuchokera ku DN50 mpaka ku DN600 sizes.Kudzipereka kwathu ku khalidwe kumawonetsedwa pogwiritsa ntchito namwali PTFE, kuonetsetsa kuti mpando uliwonse wa valve umakhala ndi mphamvu zamakina apamwamba komanso moyo wautali. Kusakwanira kwa mankhwala a PTFE kumatanthauza kuti mipando yathu ya agulugufe imakhala yosagonjetsedwa ndi mankhwala onse a mafakitale, ma asidi, ndi zosungunulira, kusunga umphumphu wawo ngakhale pansi pa zovuta kwambiri. Kuphatikizidwa ndi kulimba komanso kukana kwanyengo kwa EPDM, mipando yathu ya ma valve imalonjeza moyo wokhazikika wautumiki komanso kuchepetsa ndalama zolipirira, kuwonetsetsa kuti ntchito ikuyenda bwino komanso magwiridwe antchito apamwamba. Khulupirirani Sansheng Fluorine Plastics pazosowa zanu za valve ndikuwona kusiyana komwe kumapanga uinjiniya wolondola ndi wapamwamba-zida zamakono.

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 kwapakati: - 38°C mpaka +230°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 yapampando yoyenera nthawi zambiri kumakhala chisankho chovuta kwambiri Vavu ya Mpira Kusankha. Kuti tithandizire makasitomala athu panthawiyi, ndife okonzeka kupereka zambiri pazopempha zamakasitomala.
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 pa mankhwala athu ndi kuphatikizika kwa mphira wa EPDM (Ethylene Propylene Diene Monomer) ndi PTFE (Polytetrafluoroethylene), yomwe imadziwikanso kuti Teflon. Kuphatikizika kwa synergistic kumeneku kumabweretsa zinthu zabwino kwambiri pazida zonse ziwiri: kulimba mtima komanso kukhazikika kwa EPDM komanso kukana kwamankhwala kosayerekezeka kwa PTFE. Chotsatira chake ndi mpando wa valve womwe sumangolimbana ndi kutentha kwakukulu ndi zinthu zowonongeka komanso umatsimikizira kuti zero kutayikira, zomwe zimapangitsa kukhala chisankho chabwino pa ntchito zosiyanasiyana za mafakitale, kuchokera ku DN50 mpaka ku DN600 sizes.Kudzipereka kwathu ku khalidwe kumawonetsedwa pogwiritsa ntchito namwali PTFE, kuonetsetsa kuti mpando uliwonse wa valve umakhala ndi mphamvu zamakina apamwamba komanso moyo wautali. Kusakwanira kwa mankhwala a PTFE kumatanthauza kuti mipando yathu ya agulugufe imakhala yosagonjetsedwa ndi mankhwala onse a mafakitale, ma asidi, ndi zosungunulira, kusunga umphumphu wawo ngakhale pansi pa zovuta kwambiri. Kuphatikizidwa ndi kulimba komanso kukana kwanyengo kwa EPDM, mipando yathu ya ma valve imalonjeza moyo wokhazikika wautumiki komanso kuchepetsa ndalama zolipirira, kuwonetsetsa kuti ntchito ikuyenda bwino komanso magwiridwe antchito apamwamba. Khulupirirani Sansheng Fluorine Plastics pazosowa zanu za valve ndikuwona kusiyana komwe kumapanga uinjiniya wolondola ndi wapamwamba-zida zamakono.
