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 mwa ntchito zamagetsi komwe kumapangitsa kuti madzi am'madzi atulutse, kukhulupirika ndi kudalirika kwa zigawo zisapangidwe kwambiri. Ma Sansheng floorine plastics, ndikupangitsa kuti ukadaulo wake pazinthu zapamwamba, amapereka gawo lake prith - Chiwonetsero cha Teflon. Wopangidwa ndi namwali Ptfe (Polytetrafluoroene), nsalu iyi imayimira chikhomo cha fluoro - Kupanga pulasitiki, zomwe zidapangidwa kuti zikwaniritse zofunikira zamafakitale osiyanasiyana.
Kusankhidwa kwa zinthu, namwali Ptfe, sikuti mwangozi. Wodziwika bwino ndi dzina lake, teflonocarborbon - Polymer yochokera ku Polymer imalemekezedwa chifukwa cha kukana kwa mankhwala. Imayima mosagwirizana ndi mitundu yonse ya mafakitale ndi ma sol sol, zitsulo, zodetsa, ndi organic, zimapangitsa kuti ikhale yoyeserera yofunsira kusintha kwa mankhwala, chakudya ndi chakumwa, ndi zina zambiri. Osangokhala chabe, a PTF amadzitamandira kwambiri pazinthu zapamwamba kwambiri komanso katundu wamagetsi, kuonetsetsa kudalirika kwa malo okhala ndi kutentha kwambiri kuyambira - 200 ° C '200 ° C '00 ° C' Akuluakulu a Teflon attern ander, yopangidwa kuti agwiritsidwe ntchito mu valve argur valations, amaonetsetsa kuti zero zimadutsa kukula kwa DN50 mpaka DN600. Chinthu ichi ndichofunikira posamalira umphumphu ndi chilengedwe, makamaka m'makampani omwe kupewa kuwononga madzi ndi - kukambirana. Kusintha kwa malonda athu kumatsimikiziridwa ndi kuyika kwake kosavuta ndi kukonza, kumapangitsa kuti zikhale mtengo - Njira Yothandiza kwa Nthawi yayitali - Kugwiritsa Ntchito Nthawi yayitali - Kugwiritsa Ntchito Nthawi yayitali. Ndili ndi a Sansheng Floorine Plastine zodzipereka kwa abwino komanso chikhumbo cha makasitomala, aliyense wa teflon wa teflon.

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.

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.
Kusankhidwa kwa zinthu, namwali Ptfe, sikuti mwangozi. Wodziwika bwino ndi dzina lake, teflonocarborbon - Polymer yochokera ku Polymer imalemekezedwa chifukwa cha kukana kwa mankhwala. Imayima mosagwirizana ndi mitundu yonse ya mafakitale ndi ma sol sol, zitsulo, zodetsa, ndi organic, zimapangitsa kuti ikhale yoyeserera yofunsira kusintha kwa mankhwala, chakudya ndi chakumwa, ndi zina zambiri. Osangokhala chabe, a PTF amadzitamandira kwambiri pazinthu zapamwamba kwambiri komanso katundu wamagetsi, kuonetsetsa kudalirika kwa malo okhala ndi kutentha kwambiri kuyambira - 200 ° C '200 ° C '00 ° C' Akuluakulu a Teflon attern ander, yopangidwa kuti agwiritsidwe ntchito mu valve argur valations, amaonetsetsa kuti zero zimadutsa kukula kwa DN50 mpaka DN600. Chinthu ichi ndichofunikira posamalira umphumphu ndi chilengedwe, makamaka m'makampani omwe kupewa kuwononga madzi ndi - kukambirana. Kusintha kwa malonda athu kumatsimikiziridwa ndi kuyika kwake kosavuta ndi kukonza, kumapangitsa kuti zikhale mtengo - Njira Yothandiza kwa Nthawi yayitali - Kugwiritsa Ntchito Nthawi yayitali - Kugwiritsa Ntchito Nthawi yayitali. Ndili ndi a Sansheng Floorine Plastine zodzipereka kwa abwino komanso chikhumbo cha makasitomala, aliyense wa teflon wa teflon.
