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.
Wapamwamba - Ubwino wa Teflon Butterfly Valve Liner - Sansheng Fluorine Plastics
M'malo ogwiritsira ntchito mafakitale kumene kulamulira kwamadzimadzi kumakhala kofunika kwambiri, kukhulupirika ndi kudalirika kwa zigawo za valve sikungathe kupitirira. Sansheng Fluorine Plastics, pogwiritsa ntchito ukadaulo wake pazida zapamwamba, ikupereka chinthu chake choyambirira - Teflon Butterfly Valve Liner. Wopangidwa kuchokera ku namwali PTFE (Polytetrafluoroethylene), chingwe ichi chikuyimira nsonga ya fluoro-pulasitiki yatsopano, yopangidwa kuti ikwaniritse zofunikira zamafakitale osiyanasiyana.
Kusankha zinthu, namwali PTFE, si mwangozi. Chodziwika bwino ndi dzina la mtundu wake, Teflon, polima wopangidwa ndi fluorocarbon-amalemekezedwa chifukwa cha kukana kwake kwamankhwala. Simakhudzidwa ndi pafupifupi mankhwala onse akumafakitale ndi zosungunulira, kuphatikiza ma acid, zoyambira, ndi zosungunulira organic, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito popanga mankhwala, mankhwala, chakudya ndi zakumwa, ndi zina zambiri. Osati kokha kuzizira kwa mankhwala, PTFE imadzitamandira ndi kukhazikika kwapamwamba kwa kutentha ndi mphamvu zotetezera magetsi, kuwonetsetsa kudalirika kwa ntchito m'madera omwe ali ndi kutentha kwakukulu kuyambira -200 ° C mpaka +260 ° C. imawonetsetsa kutayikira kwa ziro pamtunda waukulu kuchokera ku DN50 mpaka DN600. Izi ndizofunikira kwambiri pakusunga kukhulupirika kwa magwiridwe antchito komanso kutsata chilengedwe, makamaka m'mafakitale omwe kupewa kutulutsa kwamadzimadzi sikungathe kukambitsirana. Kusinthika kwazinthu zathu kumatsimikiziridwa ndi mawonekedwe ake osavuta kukhazikitsa ndi kukonza, kupangitsa kuti ikhale yotsika mtengo-yothandiza pakugwiritsa ntchito nthawi yayitali. Ndi kudzipereka kwa Sansheng Fluorine Plastics ku khalidwe labwino komanso kukhutitsidwa kwa makasitomala, Teflon Butterfly Valve Liner iliyonse ndi umboni wa kudzipereka kwathu popereka mayankho omwe samangokwaniritsa komanso kupitirira miyezo ya makampani ndi ziyembekezo za makasitomala.

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 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 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, kukana kwa asidi wabwino ndi alkali ndi kukana mafuta; yokhala ndi mphamvu zobwereranso bwino, zolimba komanso zolimba popanda kutayikira.
Kusankha zinthu, namwali PTFE, si mwangozi. Chodziwika bwino ndi dzina la mtundu wake, Teflon, polima wopangidwa ndi fluorocarbon-amalemekezedwa chifukwa cha kukana kwake kwamankhwala. Simakhudzidwa ndi pafupifupi mankhwala onse akumafakitale ndi zosungunulira, kuphatikiza ma acid, zoyambira, ndi zosungunulira organic, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito popanga mankhwala, mankhwala, chakudya ndi zakumwa, ndi zina zambiri. Osati kokha kuzizira kwa mankhwala, PTFE imadzitamandira ndi kukhazikika kwapamwamba kwa kutentha ndi mphamvu zotetezera magetsi, kuwonetsetsa kudalirika kwa ntchito m'madera omwe ali ndi kutentha kwakukulu kuyambira -200 ° C mpaka +260 ° C. imawonetsetsa kutayikira kwa ziro pamtunda waukulu kuchokera ku DN50 mpaka DN600. Izi ndizofunikira kwambiri pakusunga kukhulupirika kwa magwiridwe antchito komanso kutsata chilengedwe, makamaka m'mafakitale omwe kupewa kutulutsa kwamadzimadzi sikungathe kukambitsirana. Kusinthika kwazinthu zathu kumatsimikiziridwa ndi mawonekedwe ake osavuta kukhazikitsa ndi kukonza, kupangitsa kuti ikhale yotsika mtengo-yothandiza pakugwiritsa ntchito nthawi yayitali. Ndi kudzipereka kwa Sansheng Fluorine Plastics ku khalidwe labwino komanso kukhutitsidwa kwa makasitomala, Teflon Butterfly Valve Liner iliyonse ndi umboni wa kudzipereka kwathu popereka mayankho omwe samangokwaniritsa komanso kupitirira miyezo ya makampani ndi ziyembekezo za makasitomala.
