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
Padziko lonse lapansi lolamulira ndi malangizo, kukhulupirika komanso kudalirika kwa zigawo zikuluzikulu. Sansheng floorine plastics amayambitsa malonda ake oyendayenda muofesi yowongolera yoyendetsera madzi - mpando wa PTF. Izi zimapangidwa mosamala kuti zithandizire kugwira ntchito kwa Bray Remient yokhala ndi ma valves, kupereka njira yosayerekezeredwa yomwe imaphatikiza kulimba kwapadera.
Wopangidwa ndi namwali Ptfe (polytetrafluorothylene), yomwe imadziwika kuti Teflon imakhazikitsa muyezo watsopano. PTFF amadziwika chifukwa chokana ndi mankhwala, ndikupangitsa kuti akhale chisankho chabwino pa ntchito zokhudzana ndi zinthu zowonongeka. Kuphatikiza apo, kukhazikika kwake kwamankhwala ndi zinthu zamagetsi zapadera kumapangitsa kuti ikhale yolimbana ndi mafakitale osiyanasiyana, kuyambira pokonza mankhwala kupita ku chakudya ndi chakumwa. Kulimbikitsidwa ndi kuyerekezera kwake ndi ma valve omwe ali ndi Bray omwe ali ndi ma valler omwe ali ndi chiwongola dzanja chosawoneka bwino kwambiri komanso cha DN550. Kugwiritsa ntchito namwali potfe mipando iyi kumangotsimikizira kusindikizidwa kwakumwamba komanso kumapangitsa kukhala ndi moyo komanso kudalirika. Makhalidwe osadziwika a PTF, kuphatikiza ndi umisala wopatsa chidwi, zimapangitsa kuti chinthu chizitha kupirira ziwopsezo za mafakitale ogwiritsa ntchito. Kaya ndi ntchito yosalala, kulimba pa mankhwala ankhanza, kapena kuthekera kwake kuti mugwiritse ntchito bwino kwambiri ma mavesi a Bray omwe akukhala ndi mphamvu zoyendetsera makina oyendayenda.

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: - 38 ° C '23 ° C.

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.
Wopangidwa ndi namwali Ptfe (polytetrafluorothylene), yomwe imadziwika kuti Teflon imakhazikitsa muyezo watsopano. PTFF amadziwika chifukwa chokana ndi mankhwala, ndikupangitsa kuti akhale chisankho chabwino pa ntchito zokhudzana ndi zinthu zowonongeka. Kuphatikiza apo, kukhazikika kwake kwamankhwala ndi zinthu zamagetsi zapadera kumapangitsa kuti ikhale yolimbana ndi mafakitale osiyanasiyana, kuyambira pokonza mankhwala kupita ku chakudya ndi chakumwa. Kulimbikitsidwa ndi kuyerekezera kwake ndi ma valve omwe ali ndi Bray omwe ali ndi ma valler omwe ali ndi chiwongola dzanja chosawoneka bwino kwambiri komanso cha DN550. Kugwiritsa ntchito namwali potfe mipando iyi kumangotsimikizira kusindikizidwa kwakumwamba komanso kumapangitsa kukhala ndi moyo komanso kudalirika. Makhalidwe osadziwika a PTF, kuphatikiza ndi umisala wopatsa chidwi, zimapangitsa kuti chinthu chizitha kupirira ziwopsezo za mafakitale ogwiritsa ntchito. Kaya ndi ntchito yosalala, kulimba pa mankhwala ankhanza, kapena kuthekera kwake kuti mugwiritse ntchito bwino kwambiri ma mavesi a Bray omwe akukhala ndi mphamvu zoyendetsera makina oyendayenda.
