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 Bray EPDM+PTFE Gulugufe Valve Mpando - Sansheng Fluorine Plastics
Sansheng fluorine plastine amayambitsa njira yothandizira bwino muukadaulo wa Varve - Mpando wa Bray Gledf + ptfed a hybrid ya kukhazikika kuti akwaniritse zofunika kwambiri pa magwiridwe antchito a vadzi. Zogulitsa zathu zimapangidwa mwachidule, kuphatikizapo kukana kwa mankhwala apamwamba a PTF (polytetrafluorothylene) ndi kulimba mtima kwa mphira wa EPDM, kukhazikitsa njira yatsopano ya ma valve.
Pamtima pazinthu zathu zili ndi namwaliyo. Katunduyu amapangitsa kuti valavu ya Bray ya Bray ikhale yopanga chikhomo chodalirika kwambiri m'malo omwe kuwonekera kwa mankhwala kumathandiza nthawi zonse. Kuphatikiza kwa PTF sikungowonjezera kukana kwa valavu ya valavu ya valavu yotsika mtengo komanso amasunga umphumphuwo kudzera mu spectrum kwambiri, ndikuwonetsetsa kuti mugwire ntchito zosiyanasiyana. Kuphatikiza apo, kuphatikiza kwa mphira wa epdm kulowa pampando wa valavu kumabweretsa kulimba ndi kulimba. Kuphatikiza kumeneku kumatsimikizira mazero a zero kuchokera kwa DN50 mpaka DN600, ndikupangitsa valavu yathu kukhala yovuta kwambiri pakugwiritsa ntchito mozama. Mpando wa Bray Epdm + PTFE Gulu la valavu ya Prefff si gawo chabe; Ndikudzipereka kwa mtundu ndi kudalirika, ndikuwonetsa kudzipatulira kwa ma sansheng floorine kuti zithandizire pazinthu zilizonse. Ndi katundu wapamwamba kwambiri komanso wamagetsi, mipando yathu mipando yathu imayimira ukadaulo wathu pazinthu zamasamba a fluorine

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 Valve 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.
Pamtima pazinthu zathu zili ndi namwaliyo. Katunduyu amapangitsa kuti valavu ya Bray ya Bray ikhale yopanga chikhomo chodalirika kwambiri m'malo omwe kuwonekera kwa mankhwala kumathandiza nthawi zonse. Kuphatikiza kwa PTF sikungowonjezera kukana kwa valavu ya valavu ya valavu yotsika mtengo komanso amasunga umphumphuwo kudzera mu spectrum kwambiri, ndikuwonetsetsa kuti mugwire ntchito zosiyanasiyana. Kuphatikiza apo, kuphatikiza kwa mphira wa epdm kulowa pampando wa valavu kumabweretsa kulimba ndi kulimba. Kuphatikiza kumeneku kumatsimikizira mazero a zero kuchokera kwa DN50 mpaka DN600, ndikupangitsa valavu yathu kukhala yovuta kwambiri pakugwiritsa ntchito mozama. Mpando wa Bray Epdm + PTFE Gulu la valavu ya Prefff si gawo chabe; Ndikudzipereka kwa mtundu ndi kudalirika, ndikuwonetsa kudzipatulira kwa ma sansheng floorine kuti zithandizire pazinthu zilizonse.
