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.
Mavavu Okhazikika a Bray Okhazikika - Mipando ya Gulugufe wa PTFE
M'dziko la ntchito zamafakitale, kukhulupirika kwa zigawo za valve kumagwira ntchito yofunika kwambiri pakusunga magwiridwe antchito ndi chitetezo. Sansheng Fluorine Plastics ali patsogolo popereka mayankho apamwamba kwambiri ndi Seat yathu ya PTFE Butterfly Valve Seat, yopangidwa mwapadera kuti iphatikize mopanda msoko ndi ma valve okhala pansi a Bray. Zogulitsa zathu zimatsimikizira kudalirika komanso magwiridwe antchito apamwamba kwambiri, kutengera ma diameter osiyanasiyana kuchokera ku DN50 mpaka DN600, ndikupangitsa kuti ikhale chisankho chosunthika pazinthu zosiyanasiyana zamafakitale.
Wopangidwa kuchokera ku virgin PolyTetraFluoroEthylene (PTFE), yemwe amadziwika kuti Teflon, mpando wa agulugufewa ndi chitsanzo chapamwamba kwambiri cha kukana mankhwala. PTFE imadziwika chifukwa cha zinthu zake zapadera, zomwe zimaphatikizapo kukana kwathunthu mankhwala ambiri, zomwe zimapangitsa kukhala chisankho choyenera pamafakitale ovuta. Pamodzi ndi inertness yake yamankhwala, PTFE imakhalabe ndi kukhazikika kwamafuta komanso kutentha kwamagetsi, kuwonetsetsa kuti mpando wa valve umagwira ntchito bwino pamitundu yosiyanasiyana ya kutentha ndi mikhalidwe. Izi zimapangitsa kuti mipando yathu ya PTFE Butterfly Valve Seats ikhale yokhazikika komanso yosunthika, yoyenera kugwiritsira ntchito mitundu yambiri ya ntchito.Kuphatikiza apo, kudzipereka kwathu ku umisiri wabwino ndi wolondola kumathandiza kuti ma valve okhala pansi a Bray azitha kukwaniritsa zero kutayikira. Chofunikirachi chikuwonetsetsa kuti zogulitsa zathu sizimangowonjezera chitetezo ndi miyezo ya chilengedwe cha ntchito zanu komanso zimakulitsa magwiridwe antchito ndi moyo wautali wa makina anu. Kaya mukukumana ndi zoyeretsera madzi, kukonza mankhwala, kapena kugwiritsa ntchito kulikonse komwe kumafuna kukhulupirika kwapamwamba kwambiri komanso kukana mankhwala, Sansheng Fluorine Plastics' PTFE Butterfly Valve Seat imapereka yankho losayerekezeka. Ndi kudzipereka kwathu pazatsopano komanso kuchita bwino, sitingopereka zinthu zokhazokha koma mayankho athunthu omwe amakwaniritsa ndikupitilira miyezo yofunikira yamafakitale amakono.

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.
Wopangidwa kuchokera ku virgin PolyTetraFluoroEthylene (PTFE), yemwe amadziwika kuti Teflon, mpando wa agulugufewa ndi chitsanzo chapamwamba kwambiri cha kukana mankhwala. PTFE imadziwika chifukwa cha zinthu zake zapadera, zomwe zimaphatikizapo kukana kwathunthu mankhwala ambiri, zomwe zimapangitsa kukhala chisankho choyenera pamafakitale ovuta. Pamodzi ndi inertness yake yamankhwala, PTFE imakhalabe ndi kukhazikika kwamafuta komanso kutentha kwamagetsi, kuwonetsetsa kuti mpando wa valve umagwira ntchito bwino pamitundu yosiyanasiyana ya kutentha ndi mikhalidwe. Izi zimapangitsa kuti mipando yathu ya PTFE Butterfly Valve Seats ikhale yokhazikika komanso yosunthika, yoyenera kugwiritsira ntchito mitundu yambiri ya ntchito.Kuphatikiza apo, kudzipereka kwathu ku umisiri wabwino ndi wolondola kumathandiza kuti ma valve okhala pansi a Bray azitha kukwaniritsa zero kutayikira. Chofunikirachi chikuwonetsetsa kuti zogulitsa zathu sizimangowonjezera chitetezo ndi miyezo ya chilengedwe cha ntchito zanu komanso zimakulitsa magwiridwe antchito ndi moyo wautali wa makina anu. Kaya mukukumana ndi zoyeretsera madzi, kukonza mankhwala, kapena kugwiritsa ntchito kulikonse komwe kumafuna kukhulupirika kwapamwamba kwambiri komanso kukana mankhwala, Sansheng Fluorine Plastics' PTFE Butterfly Valve Seat imapereka yankho losayerekezeka. Ndi kudzipereka kwathu pazatsopano komanso kuchita bwino, sitingopereka zinthu zokhazokha koma mayankho athunthu omwe amakwaniritsa ndikupitilira miyezo yofunikira yamafakitale amakono.
