Padziko lonse lapansi la zolengedwa ndi mavavu, kukhulupirika ndi kudalirika kwa magawo a zinthu zopambana za dongosololi. Sansheng fluorine plastics amayambitsa kudula kwake - Njira Yabwino - PtFE EPDM yophika gulugufe. Izi zikuyimira chikhomo chamitundu ya valavu ya valavu, kuphatikiza mankhwala osokoneza bongo a PTF (polytetrafluoroenene) ndi kulimba kwa mphira wa EPDM. Anapangidwa kuti azitha kusamba mzawo osiyanasiyana kuchokera kwa DN50 kudzera dn600, ulusiwu umatsimikizira kukhala woyenera wa agumba wa Gulugufe.

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.

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 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, asidi wabwino ndi alkali kukana ndi kukana mafuta; yokhala ndi mphamvu zobwereranso bwino, zolimba komanso zolimba popanda kutsika.
