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 yotsika ya kukangana, zoteteza kwambiri.
Mavavu Okhazikika a Bray Okhazikika - PTFE Gulugufe Mipando
M'dziko la kayendetsedwe ka madzimadzi ndi kulamulira, kukhulupirika ndi kudalirika kwa zigawo za valve ndizofunika kwambiri. Sansheng Fluorine Plastics imayambitsa chida chake chodziwika bwino pamayankho owongolera otaya - Mpando wa PTFE Butterfly Valve. Izi zidapangidwa mwaluso kuti zithandizire magwiridwe antchito a Bray resilient resilient valves, ndikupereka njira yosindikizira yosayerekezeka yomwe imaphatikiza kulimba ndi magwiridwe antchito apadera.
Wopangidwa kuchokera kwa namwali PTFE (Polytetrafluoroethylene), yemwe amadziwika kuti Teflon, mpando wa valve uwu umakhazikitsa njira yatsopano yamakampani. PTFE imadziwika chifukwa chokana kwambiri mankhwala, ndikupangitsa kuti ikhale chisankho chabwino pamapulogalamu okhudzana ndi zida zowononga. Kuphatikiza apo, kukhazikika kwake kwapadera kwamafuta komanso mphamvu zotchinjiriza zamagetsi kumapangitsa kuti ikhale yosunthika m'mafakitale osiyanasiyana, kuyambira pakukonza mankhwala mpaka kupanga zakudya ndi zakumwa. Kulimbikitsidwa ndi kuyanjana kwake ndi ma valve okhala pansi a Bray, mpando wathu wa agulugufe wa PTFE umaonetsetsa kuti valavu yagulugufe ya PTFE imagwira ntchito mopanda msoko komanso imagwira ntchito popanda kutayikira pamitundu yambiri (DN50 - DN600), kuti ikwaniritse zofunikira zambiri. mipando ya valve sikuti imangotsimikizira chisindikizo chapamwamba komanso imatsimikizira kuti moyo wautali ndi wodalirika. Makhalidwe achilengedwe a PTFE, ophatikizidwa ndi uinjiniya waluso, amabweretsa chinthu chomwe chimatha kupirira zovuta zakugwiritsa ntchito mafakitale popanda kusokoneza magwiridwe antchito. Kaya ndikugwira ntchito bwino, kulimba mtima motsutsana ndi mankhwala owopsa, kapena kuthekera kwake kogwira ntchito bwino pakutentha kwakukulu, mpando wathu wagulugufe wa PTFE umathandizira magwiridwe antchito a ma valve okhala pansi a Bray, ndikupangitsa kuti ikhale gawo lofunikira pamafakitale omwe akufuna kulondola komanso kukhazikika pakuyenda kwawo. machitidwe owongolera.

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 yotsika ya kukangana, 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.
Wopangidwa kuchokera kwa namwali PTFE (Polytetrafluoroethylene), yemwe amadziwika kuti Teflon, mpando wa valve uwu umakhazikitsa njira yatsopano yamakampani. PTFE imadziwika chifukwa chokana kwambiri mankhwala, ndikupangitsa kuti ikhale chisankho chabwino pamapulogalamu okhudzana ndi zida zowononga. Kuphatikiza apo, kukhazikika kwake kwapadera kwamafuta komanso mphamvu zotchinjiriza zamagetsi kumapangitsa kuti ikhale yosunthika m'mafakitale osiyanasiyana, kuyambira pakukonza mankhwala mpaka kupanga zakudya ndi zakumwa. Kulimbikitsidwa ndi kuyanjana kwake ndi ma valve okhala pansi a Bray, mpando wathu wa agulugufe wa PTFE umaonetsetsa kuti valavu yagulugufe ya PTFE imagwira ntchito mopanda msoko komanso imagwira ntchito popanda kutayikira pamitundu yambiri (DN50 - DN600), kuti ikwaniritse zofunikira zambiri. mipando ya valve sikuti imangotsimikizira chisindikizo chapamwamba komanso imatsimikizira kuti moyo wautali ndi wodalirika. Makhalidwe achilengedwe a PTFE, ophatikizidwa ndi uinjiniya waluso, amabweretsa chinthu chomwe chimatha kupirira zovuta zakugwiritsa ntchito mafakitale popanda kusokoneza magwiridwe antchito. Kaya ndikugwira ntchito bwino, kulimba mtima motsutsana ndi mankhwala owopsa, kapena kuthekera kwake kogwira ntchito bwino pakutentha kwakukulu, mpando wathu wagulugufe wa PTFE umathandizira magwiridwe antchito a ma valve okhala pansi a Bray, ndikupangitsa kuti ikhale gawo lofunikira pamafakitale omwe akufuna kulondola komanso kukhazikika pakuyenda kwawo. machitidwe owongolera.
