PTFE Foda Plasma Hydrophilic Jiyya
PTFE foda An yi amfani da ko'ina a matsayin ƙari a cikin daban-daban ƙarfi-tushen coatings da foda shafi, kamar filastik coatings, itace Paint, nada coatings, UV curing coatings, da Paint, don inganta su mold saki yi, surface karce juriya, lubricity, sinadaran juriya, juriya yanayi, da hana ruwa. PTFE Ana iya amfani da ƙananan foda a matsayin mai ƙoshin mai mai ƙarfi maimakon lubricants na ruwa. Hakanan za'a iya amfani da su don haɓaka kwararar tawada kuma azaman wakili na rigakafin sawa, tare da ƙari na al'ada na 1-3wt%. Hakanan za'a iya amfani da su a cikin suturar da ba na sanda ba don kayan dafa abinci, tare da adadin ƙari na yau da kullun wanda bai wuce 5wt% ba. Hakanan za'a iya amfani da tarwatsewar sauran ƙarfi azaman wakili na saki. Hakanan za'a iya amfani da su azaman magungunan anti-drip masu tasiri sosai a cikin robobi daban-daban, kamar ABS, polycarbonate (PC), polyurethane (PU), da polystyrene (PS).
PTFE shi ne polymer crystalline da aka yi daga tetrafluoroethylene monomers, tare da kyakkyawan rufin lantarki, ƙananan tashin hankali da juzu'i, rashin ƙonewa, juriya ga tsufa na yanayi, haɓaka mai girma da ƙananan zafin jiki, da manyan kayan aikin injiniya.
Duk da haka, saboda tsarinsa na daidaitacce kuma maras iyaka, rashin ƙungiyoyi masu aiki, da babban crystallinity. PTFE wani abu ne wanda ba na iyakacin duniya ba tare da karfi hydrophobicity, sinadarai inertness, low surface makamashi, da kuma matalauta wettability da adhesion zuwa wasu kayan, wanda ƙwarai iyaka aikace-aikace. Saboda haka, don fadada aikace-aikace na PTFE, dole ne a kula da samansa don ƙara ƙarfin samansa da inganta yanayin ruwa.
Maganin Plasma ɗaya ne daga cikin fasahar haɓaka cikin sauri don PTFE gyaran fuska a cikin 'yan shekarun nan. Ka'idar gyare-gyaren plasma shine yin amfani da ion bombardment ko allura zuwa saman polymer don samar da karyewar shaidu ko gabatar da ƙungiyoyi masu aiki, don haka kunna saman don haɓaka mannewar kayan. Gas na yau da kullun da ake amfani da su sun haɗa da oxygen, hydrogen, nitrogen, carbon tetrafluoride, da argon. Bama-bamai na plasma inert gas na iya canza tsarin saman copolymer.
Plasma ya ƙunshi barbashi masu aiki kamar su electrons, ions, da free radicals. Gyaran fuskar plasma ya haɗa da gyaran jiki da sinadarai. Gyaran jiki shine bama-bamai na electrons da ions akan saman polymer, wanda ke karya haɗin sinadarai na sarkar polymer, yana haifar da halayen lalacewa, kuma ya samar da samfuran lalacewa waɗanda ke ajiyewa akan saman polymer. Gyaran sinadarai ya haɗa da gabatar da ƙungiyoyi masu aiki ta hanyar radicals masu kyauta suna amsawa tare da farfajiyar polymer, canza yanayin sinadarai na saman. Dukansu gyare-gyaren jiki da na sinadarai zasu haifar da canje-canje a cikin abubuwan da ke sama. A lokacin jiyya na plasma, gabatarwar ƙungiyoyin aiki da halayen lalata ba za a iya raba su ba amma suna faruwa a lokaci ɗaya, kuma halayen lalata ba makawa. Makullin ingantaccen gyaran ƙasa shine a rage girman halayen lalacewa da kuma ƙara girman aikin gabatarwar ƙungiyar aiki.
The PTFE gyaran foda yana amfani da injin tsabtace plasma foda. Plasma yana aiki akan foda don canza dabi'unsa na zahiri da sinadarai, yayin da yake riƙe da ainihin kaddarorin foda, don ba shi sabbin kaddarorin ƙasa, canza kayan sa daga hydrophobic zuwa hydrophilic ko akasin haka, don haka inganta wettability na barbashi foda kuma inganta mannewa na foda barbashi a cikin matsakaici.
