PTFE (polytetrafluoroethylene) tchire, omwe amadziwikanso kuti tchire la Teflon, amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha katundu wawo wapadera komanso ubwino. Ku China,Zithunzi za PTFEamapangidwa ndikuperekedwa ndi makampani ambiri, kuwapangitsa kukhala odziwika pamapulogalamu ambiri. PoyerekezaZithunzi za PTFEkwa miyambo zitsulo kapena pulasitiki bushings, m'pofunika kuganizira ubwino ndi kuipa kudziwa njira yabwino kwambiri zofunika zinazake.
Ubwino wa PTFE Bushes:
1. Low Friction: PTFE ili ndi coefficient yotsika kwambiri ya mikangano, ndikupangitsa kukhala chisankho chabwino kwambiri pamagwiritsidwe ntchito komwe kumafunikira kuyenda kosalala komanso kosasintha. Katunduyu amachepetsa kung'ambika ndi kung'ambika pamitengo ndi malo okwerera, zomwe zimapangitsa moyo wautali wautumiki ndikuwongolera bwino.
2. Chemical Resistance: PTFE imalimbana kwambiri ndi mankhwala, ma asidi, ndi zosungunulira, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo owononga. Kukaniza uku kumatsimikizira kuti tchire zimakhalabe zosakhudzidwa ndi zinthu zozungulira, kusunga umphumphu ndi ntchito zawo pakapita nthawi.
3. Kutentha Kulimbana: PTFE tchire akhoza kupirira osiyanasiyana kutentha, kuchokera otsika kwambiri kutentha kwambiri, popanda kutaya makina katundu. Izi zimawapangitsa kukhala oyenera ntchito zomwe kusintha kwa kutentha kumakhala kofala.
4. Kudzipaka mafuta: PTFE ili ndi chibadwa chodzipaka mafuta, kuthetsa kufunika kowonjezera mafuta. Izi zimachepetsa zofunikira zosamalira ndikuonetsetsa kuti tchire likuyenda bwino popanda chiopsezo chowuma.
5. Insulating Properties: PTFE ndi insulator yabwino kwambiri yamagetsi, yomwe imapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe magetsi amayenera kuchepetsedwa. Katunduyu amalepheretsa arcing yamagetsi ndikuwonetsetsa chitetezo cha zida ndi ogwira ntchito.
Kuipa kwa PTFE Bushes:
1. Mtengo: Zitsamba za PTFE zitha kukhala zodula kuposa zitsulo zachikhalidwe kapena pulasitiki, zomwe zingakhudze mtengo wonse wa zida kapena ntchito. Komabe, phindu lanthawi yayitali la tchire la PTFE nthawi zambiri limaposa ndalama zoyambira.
2. Katundu Kuthekera: Ngakhale PTFE ali kwambiri otsika mikangano katundu, akhoza kukhala ndi malire mu mkulu-katundu ntchito poyerekeza ndi zitsulo bushings. Ndikofunika kuganizira zofunikira za katundu posankha tchire la PTFE pa ntchito inayake.
3. Machinability: PTFE ndizovuta kwa makina, zomwe zingapangitse kupanga kupanga kukhala kovuta komanso nthawi yambiri. Izi zitha kupangitsa kuti pakhale nthawi yayitali yotsogolera tchire la PTFE.
Poyerekeza ndi Traditional Metal Bushings:
Zitsulo zachitsulo, monga mkuwa kapena zitsulo, zimadziwika ndi mphamvu zawo zolemetsa komanso zolimba. Komabe, angafunike kuthira mafuta kuti achepetse kukangana ndi kuvala. Mosiyana ndi izi, tchire la PTFE limapereka mikangano yotsika popanda kufunikira kowonjezera mafuta owonjezera, kuwapanga kukhala oyenera kugwiritsa ntchito pomwe kukonza kuyenera kuchepetsedwa.
Kuonjezera apo, zitsulo zazitsulo zimatha kuwonongeka m'madera ena, pamene tchire la PTFE ndi lolimba kwambiri ku dzimbiri ndi kukhudzana ndi mankhwala. Izi zimapangitsa tchire la PTFE kukhala chisankho chokonda kugwiritsa ntchito pomwe zinthu zachilengedwe zimatha kukhudza magwiridwe antchito.
Poyerekeza ndi Zomera Zapulasitiki Zachikhalidwe:
Zitsamba zapulasitiki, kuphatikiza nayiloni ndi polyurethane, ndizopepuka komanso zotsika mtengo pazogwiritsa ntchito zambiri. Komabe, iwo sangapereke mlingo womwewo wa mankhwala ndi kutentha kukana monga PTFE tchire. Zitsamba za PTFE zimachita bwino m'malo ovuta kugwira ntchito pomwe ma pulasitiki achikhalidwe amatha kunyozeka kapena kulephera.
Kuphatikiza apo, tchire la PTFE lili ndi zinthu zotsika kwambiri zotsika poyerekeza ndi ma pulasitiki ambiri, zomwe zimapereka magwiridwe antchito osavuta komanso owoneka bwino pamagwiritsidwe osiyanasiyana. Izi zimapangitsa tchire la PTFE kukhala chisankho chokonda pazida zogwira ntchito kwambiri komanso zolondola.
Pomaliza, tchire la PTFE limapereka kuphatikiza kwapadera kwazinthu zomwe zimawapangitsa kukhala osinthika komanso odalirika pazosankha zosiyanasiyana. Ngakhale atha kukhala ndi malire potengera kuchuluka kwa katundu ndi mtengo wake, kugundana kwawo kocheperako, kukana kwamankhwala, kukana kutentha, zodzipangira okha mafuta, ndi zoteteza kumasiyanitsa ndi zitsulo zachikhalidwe kapena pulasitiki. Posankha bushings kwa ntchito yeniyeni, m'pofunika kuwunika mosamala zofunikira ndikuganizira ubwino ndi kuipa kwa tchire la PTFE kuti mupange chisankho choyenera. Ku China, kupezeka kwa tchire la PTFE kuchokera kwa opanga odziwika bwino kumawonjezera kukopa kwawo ngati njira yothetsera zosowa zosiyanasiyana zamafakitale ndi zamalonda.
