Shin PTFE iri ɗaya ne da fiber carbon?

PTFEkuma carbon fiber ba abu ɗaya bane.A yau, za mu gabatar muku da kayan biyu.

PTFE robobi ne mai dauke da fluorine, wanda kuma aka sani da Teflon, Teflon, da sauransu.Farashin PTFEkuma ana kiranta da Sarkin Filastik saboda kwazonsa ta kowane fanni.PTFE na iya tsayayya da lalata, high da ƙananan yanayin zafi, ba mai guba ba ne, kyakkyawan rufi, anti-tsufa, high lubrication, da sauran kyawawan kaddarorin.Duk da haka, akwai kaddarorin da yawa waɗanda ke buƙatar haɓakawa, irin su creep, non-stick, juriya na abrasion, kumburin layi da juriya na matsa lamba, taurin da sauransu.Domin kara inganta wadannan kaddarorin na PTFE, sauran abubuwa kamar molybdenum disulfide, gilashin fiber, graphite, polyphenylene guduro, gilashin fiber, da karfe foda za a iya ƙara zuwa albarkatun kasa na PTFE a gwargwado.Bugu da kari na carbon fibers ne na kowa hanya na gyara PTFE kayayyakin.Matsayin fibers na carbon a cikin cika PTFE shine haɓaka juriya mai raɗaɗi, juriya mai ɗaukar nauyi, juriya juriya, kwanciyar hankali mai girma, ƙarfin ƙarfi da sauran kaddarorin naAmfani da PTFE.

Carbon fiber (CF a takaice) sabon nau'in kayan fiber ne tare da babban ƙarfi da maɗaukakin modules mai ɗauke da fiye da 95% carbon.Yana da wani microcrystalline graphite abu da aka yi da kwayoyin zaruruwa kamar flake graphite microcrystals stacked a cikin axial shugabanci na zaruruwa, wanda ake sarrafa ta carbonization da graphitization.Fiber Carbon “mai laushi ne a waje amma mai kauri a ciki”, yana da nauyi fiye da aluminium amma ya fi qarfe ƙarfi, kuma yana da sifofin juriya na lalata da maɗaukakin maɗaukaki, yana mai da shi muhimmin abu a aikace-aikacen tsaro da na jama'a.Ba wai kawai yana da kaddarorin abubuwan da suka dace na kayan carbon ba amma kuma yana da laushi da iya aiki na zaruruwan yadi, yana mai da shi sabon ƙarni na ƙarfafa zaruruwa.Carbon fiber yana da kyawawan kaddarorin da yawa.Yana da babban ƙarfin axial da modulus, ba mai rarrafe, kyakkyawan juriya na gajiya, takamaiman zafi da ƙarfin lantarki tsakanin waɗanda ba ƙarfe da ƙarfe ba, da garkuwar lantarki mai kyau.Matsakaicin haɓakar haɓakar thermal ƙananan ƙananan ne, juriya na lalata yana da kyau, ƙarancin zaruruwa kaɗan ne, ƙarancin hasken X-ray yana da kyau, taro yana da haske, kuma yanayin da ba oxidizing yana da tsayayya da matsanancin zafi.Idan aka kwatanta da filayen gilashi na al'ada, fiber carbon fiber yana da fiye da sau uku modules na matasa.Idan aka kwatanta da Kevlar, Matsalolin Matasa ya kai kusan ninki biyu, kuma ba shi da narkewa kuma yana kumbura a cikin kaushi na halitta, acid da alkalis, kuma yana da juriya na lalata.Bugu da ƙari na carbon fiber yana inganta ƙarfin ɗaukar nauyin kayan haɗin gwiwar, kuma ana ƙara ƙaramin adadin graphite a lokaci guda kamar PTFE tare da kayan cikawa na carbon fiber.Bugu da ƙari na graphite yana rage daidaituwar juzu'i tsakanin farfajiyar fiber carbon da takwaransa, don haka rage halayen fiber carbon don faɗuwa da haɓaka juriyar lalacewa na kayan haɗin gwiwa.
