Sitima yoyamba yapanyanja ya China yowoloka mothamanga kwambiri pakati pa Fuzhou ndi Xiamen ikubwera, pomwe mlatho wokhala ndi chingwe wamangidwa bwino mothandizidwa ndiPTFE polytetrafluoroethylene, mfumu ya mapulasitiki.Tilankhule za kugwiritsa ntchito PTFE komwe sikudziwika kwa inu.
Taicheng Xite Bridge ndi umodzi mwa milatho pakati pa Fujian ndi Xiamen High-speed Railway.Mlathowu wapangidwa ngati mlatho wozungulira wopanda chingwe wokhala ndi kulemera kwa matani 38,000.Kutalika konse kwa gawo lozungulira ndi 221.3 metres, yomwe ndi mlatho waukulu kwambiri wosasunthika wozungulira wa njanji yothamanga kwambiri ku China potengera matani.
Kodi chinthu chachikulu chotere chokhala ndi matani oterowo chimakwaniritsa bwanji "kusintha kokongola"?Izi sizingachitike popanda fluoropolymer yogwira ntchito kwambiri: teflon sliders.Kodi slide yaing'ono ya Teflon ingapange bwanji mlatho wa matani 10,000 kutembenuka momasuka?
Mfundo yofunikira ya thupi lozungulira ndikukhazikitsa hinge yotsetsereka ya mpira pakati pa mawonekedwe apamwamba ndi apansi a thupi lozungulira lomwe silingagwirizane ndi kuthamanga kwakukulu ndipo limakhala ndi coefficient yaing'ono ya kukangana.Hinge ya mpira imapangidwa ndi kumtunda kwa mpira, kusinthidwateflon sliderndi kutsika kwa mpira,ndikumtunda ndi kumunsi kwa mpirasili pamwamba ndi pansi turntable.
M'mawu osavuta, mfundoyi ndi yofanana ndi diski yopera mwala, pomwe maziko samasuntha ndipo gawo lapamwamba limazungulira pozungulira.Chifukwa chake mphamvu yolimbana pakati pa ma hinji a mpira imayenera kugonjetsedwera panthawi yokokera.Momwe mungachepetsere kukana kwamphamvu ndiye vuto lalikulu laukadaulo pakumanga thupi lozungulira.
PTFEsliderzimagwira ntchito yofunika kwambiri chifukwa chakekudzithira bwino kwambiri,otsikitsitsadynamic and static friction coefficient, ndi kuvalandi kukakamizidwakukaniza.Mukamaliza kukhazikitsa PTFEslider,kumtunda ndi kumunsi kwa mpirasndipo shaft yapakati imakutidwateflon ufa wothira mafuta sing'anga,zomwe zingathekuchepetsafkudzudzula.Kuphatikiza apo, shaft yozungulira ili ndiPTFEchubu, chomwe chingachepetse kukangana komwe kumapangidwa potembenuza thupi.Izi ayaying'onoPTFEsliderayenerahave mphamvu zodabwitsa chotero!
Zotsatira za PTFE
● Kukana kutentha kwakukulu
Kutentha kwake kogwira ntchito kumatha kufika 250 ℃.
● Kukana kutentha kochepa
Ili ndi kulimba kwamakina abwino pa kutentha kochepa;ngakhale kutentha kutsika mpaka -196 ℃, kumatha kusunga 5% elongation.
● Kukana dzimbiri
Ndiwopanda mankhwala ambiri ndi zosungunulira, ndipo zimatha kukana ma asidi amphamvu ndi alkalis, madzi ndi zosungunulira zosiyanasiyana.
● Kulimbana ndi nyengo yabwino
Ili ndi moyo wokalamba wabwino kwambiri pakati pa mapulasitiki.
● Mafuta ochuluka
PTFE ili ndi coefficient yotsika kwambiri ya kukangana pakati pa zinthu zolimba.
● Zosamatira
Zili ndi zovuta kwambiri pamtunda pakati pa zipangizo zolimba, ndipo sizimamatira kuzinthu zilizonse.
Mapulogalamu a mfumu yamapulasitiki
PTFE zikhoza kukhala mapepala, machubu, ndodo, mafilimu, ulusi ndi zokutira malinga ndi gulu mankhwala, ndipo chimagwiritsidwa ntchito m'madera osiyanasiyana monga mankhwala, mafuta, nsalu, magetsi ndi zamagetsi, mankhwala, makina ndi zakuthambo.
● Zachipatala
PTFE ndi madzi kugonjetsedwa, physiologically inert, ndi sanali zomatira, choncho ntchito zambiri kukonzanso minofu zipangizo ndi yokumba chiwalo zipangizo, monga yokumba mitsempha ya magazi, ndi nembanemba mtima kukonza, etc. PTFE akhoza chosawilitsidwa ntchito njira iliyonse, ndipo adzatero. osanyozeka mukatenthedwa ndi kuthamanga kwambiri kapena kuthandizidwa ndi mankhwala ophera tizilombo osiyanasiyana.Chifukwa chake, amagwiritsidwa ntchito kwambiri m'zida zamankhwala monga ma sutures, mapadi osabala, ndi singano za jakisoni.
● Zamagetsi ndi zamagetsi
PTFE ili ndi zida zabwino kwambiri za dielectric komanso kukhazikika kwamafuta kwambiri, ndipo ndi chinthu chosasinthika chamagetsi, chomwe chimagwira ntchito yofunika kwambiri pakutchinjiriza kwamagetsi ndi zamagetsi.Mwachitsanzo, nsalu ya lacquer ya galasi ya PTFE imagwiritsidwa ntchito popanga kutentha kwapamwamba komanso zipangizo zamakono zowonongeka, zomwe zingagwiritsidwe ntchito poyankhulana ndi satellite ndi makompyuta;Chithunzi cha PTFEamagwiritsidwa ntchito popanga ma capacitors ngati chotchinga chosanjikiza, padding ndi zingwe pakati pa zida;PTFE machubu woonda-mipanda ya calibers osiyana angagwiritsidwe ntchito malaya kutsogolo waya, kutentha shrinkage machubu ndi machubu ozungulira, ndi insulated mipope kutsogolera kwa jenereta, etc.
M'munda wa mauthenga a 5G, PTFE imagwiritsidwanso ntchito kwambiri pazosefera zapansi, PCB/FPC yothamanga kwambiri, 5G chip process ndi zolumikizira zapamwamba ndi zingwe.Pakadali pano, zosefera za 5G zomwe zimagwiritsidwa ntchito ndi ogulitsa zida zazikulu zoyankhulirana zimapangidwabe ndi zosefera zazitsulo zazitsulo, zomwe zimagwiritsa ntchito zigawo zambiri za PTFE pothandizira ndi kutsekereza.
● Zimango
Kwa mtundu uliwonse wa makina ndi zida, mafuta odzola ayenera kuchitidwa kuti azitha kutsetsereka panthawi ya opaleshoni kuti achepetse kugundana, kuchepetsa kutentha ndi kutentha kwa zigawozo, kuonetsetsa kuti magwiridwe antchito abwinobwino, kulondola komanso kugwiritsa ntchito mphamvu kwa makina ndi zida.PTFE's low coefficient of friction and self-coefficient of self-lubricating properties amalola kuti agwiritsidwe ntchito popanga zitsulo, mphete za pistoni, maupangiri a zida zamakina ndi zida zosindikizira, koma nthawi zambiri amagwiritsidwa ntchito pazida zolondola kapena malo osamva asidi ndi alkali chifukwa ndi okwera mtengo.
● Zovala
Zowonjezera PTFE(e-PTFE) filimu ndi laminated ndi nsalu wamba kupanga madzi ndi chinyezi permeable nsalu laminated.Makhalidwe ake abwino kwambiri amphamvu kwambiri, kuchepa pang'ono, kusamata ndi kukalamba kwa UV kumapangitsa kuti e-PTFE fiber ikhale yosankha zovala zamasewera akunja.Kuphatikiza apo, nthawi zambiri amapangidwa kukhala masuti ozimitsa moto, suti za astronaut, suti zodzitchinjiriza zamankhwala, zida zankhondo zankhondo, matumba ogona ndi mahema opepuka.
● Magalimoto & zoyendera
Pazinthu zosindikizira zamafuta zamagalimoto, zimatha kusiyanitsa magawo omwe amafunikira mafuta m'magawo otumizira kuchokera kumadera omwe akutuluka kuti aletse kutayikira kwamafuta opaka.PTFE breathable filimu ntchito magetsi magalimoto kulinganiza kuthamanga mkati ndi kunja magetsi ndi kupewa kuipitsa madzi, fumbi, ndi madzimadzi magalimoto, etc.
● Mankhwala
PTFE, chifukwa cha kukana kwake kwa dzimbiri, imagwiritsidwa ntchito ngati zinthu zotsutsana ndi dzimbiri kupanga mbali zosiyanasiyana zotsutsana ndi dzimbiri, monga mapaipi, mavavu, mapampu ndi zida zapaipi.Pazida zamakina, imatha kupanga zingwe ndi zokutira zopangira ma reactors, nsanja za distillation ndi zida zothana ndi dzimbiri.
Pezani wopanga bwino kwambiri wa PTFE
Kugwiritsa ntchito kwambiri zinthu za PTFE, kulibwino kusankha opanga PTFE, ndi SuKo, China odziwika bwino.PTFE chubu wopanga, ndiye chisankho chabwino kwambiri.Katswiri mu PTFE/UHMWPE extrusion ndi mankhwala amitundu yosiyanasiyana ndi zitsanzo, Suko amakhala patsogolo pa makampani Tetrafluorohydrazine ndi luso luso, ntchito ndi luntha onse m'dziko ndi kunja.
