Kodi PTFE ndi yofanana ndi carbon fiber?

PTFEndi carbon fiber sizinthu zomwezo.Lero, tikudziwitsani zida ziwirizi.

PTFE ndi pulasitiki wokhala ndi fluorine, wotchedwanso Teflon, Teflon, etc.PTFE pulasitikiamadziwikanso kuti King of Plastics chifukwa chakuchita bwino kwambiri pazinthu zonse.PTFE akhoza kukana dzimbiri, kutentha kwambiri ndi otsika, si poizoni, kutchinjiriza kwambiri, odana ndi ukalamba, kondomu mkulu, ndi zina zabwino kwambiri katundu.Komabe, pali zinthu zambiri zomwe zimayenera kukonzedwa bwino, monga kukwawa, kusagwira ndodo, kukana abrasion, kutupa kwa mzere ndi kukana kupanikizika, kuuma ndi zina zotero.Pofuna kupititsa patsogolo zinthu izi za PTFE, zinthu zina monga molybdenum disulfide, galasi CHIKWANGWANI, graphite, polyphenylene utomoni, galasi CHIKWANGWANI, ndi zitsulo ufa akhoza kuwonjezeredwa kwa zopangira za PTFE molingana.Kuwonjezera kwa carbon ulusi ndi njira wamba zosintha PTFE mankhwala.Udindo wa ulusi wa kaboni pakudzaza PTFE ndikuwonjezera kukana, kukana katundu, kukana kuvala, kukhazikika kwa mawonekedwe, mphamvu zamanjenje ndi zina zaPTFE amagwiritsa ntchito.

Mpweya wa carbon (CF mwachidule) ndi mtundu watsopano wa zinthu zamtundu wamtundu womwe uli ndi mphamvu zambiri komanso modulus wapamwamba wokhala ndi mpweya woposa 95%.Ndi microcrystalline graphite zakuthupi zopangidwa ndi organic fibers monga flake graphite microcrystals zodzaza mu axial direction ya ulusi, zomwe zimakonzedwa ndi carbonization ndi graphitization.Mpweya wa carbon ndi "wofewa kunja koma wolimba mkati", wopepuka kwambiri kuposa aluminiyamu koma wamphamvu kuposa chitsulo, ndipo ali ndi makhalidwe otsutsana ndi dzimbiri komanso modulus yapamwamba, zomwe zimapangitsa kuti zikhale zofunika kwambiri pachitetezo ndi ntchito za boma.Sikuti ili ndi chibadwa cha zinthu za carbon, komanso ili ndi kufewa ndi kusinthika kwa ulusi wa nsalu, zomwe zimapangitsa kukhala mbadwo watsopano wa ulusi wolimbitsa.Mpweya wa carbon uli ndi zinthu zambiri zabwino kwambiri.Lili ndi mphamvu za axial ndi modulus, palibe kukwawa, kukana kutopa kwabwino, kutentha kwapadera ndi kayendedwe ka magetsi pakati pa zopanda zitsulo ndi zitsulo, ndi chitetezo chabwino cha electromagnetic.Coefficient ya kukula kwa matenthedwe ndi yaying'ono, kukana kwa dzimbiri ndikwabwino, kachulukidwe ka ulusi ndi wotsika, X-ray permeability ndi yabwino, unyinji wake ndi wopepuka, ndipo malo osakhala oxidizing amalimbana ndi kutentha kwambiri.Poyerekeza ndi ulusi wagalasi wamba, kaboni fiber imakhala ndi modulus ya Young kuwirikiza katatu.Poyerekeza ndi Kevlar, Young's modulus ndi yokwera kuwirikiza kawiri, ndipo sisungunuka komanso kutupa mu zosungunulira za organic, ma acid ndi ma alkalis, ndipo imakhala yolimbana ndi dzimbiri.Kuphatikizika kwa mpweya wa kaboni kumathandizira kwambiri mphamvu yonyamula katundu wazinthu zophatikizika, ndipo graphite yaying'ono imawonjezeredwa nthawi yomweyo PTFE kuphatikiza zinthu zodzaza mpweya wa kaboni.Kuphatikiza kwa graphite kumachepetsa kugundana kwapakati pa kaboni CHIKWANGWANI pamwamba ndi mnzake, motero kuchepetsa chizolowezi mpweya CHIKWANGWANI kugwa ndi kuwongolera kuvala kukana kwa zinthu gulu.
