Polychlorotrifluoroethylene (PCTFE ko PTFCE) Kayayyakin & Aikace-aikace

Polychlorotrifluoroethylene (PCTFE ko PTFCE) shine chlorofluoropolymer thermoplastic tare da tsarin kwayoyin halitta (CF2CClF) n, inda shine adadin raka'o'in monomer a cikin kwayoyin polymer.Yana kama da polytetrafluoroethene (PTFE), sai dai cewa shine homopolymer na monomer chlorotrifluoroethylene (CTFE) maimakon tetrafluoroethene.Yana da mafi ƙarancin watsa tururin ruwa na kowane filastik.

Kayayyaki CTFE yana da ƙarfin ƙarfi mai ƙarfi da kyawawan halayen thermal.Ba shi da flammable kuma zafin zafi ya kai 175 ° C.Yana da ƙarancin haɓakawar haɓakar thermal.Matsakaicin canjin gilashin (Tg) yana kusa da 45 ° C.PCTFE yana da ɗayan mafi girman ƙayyadaddun iskar oxygen (LOI).Yana da kyakkyawan juriya na sinadarai.Hakanan yana baje kolin kaddarorin kamar shayar danshi da rashin jika.Ba ya ɗaukar hasken da ake iya gani.Lokacin da aka yi wa radiation mai ƙarfi, yana jurewa, kamar PTFE, lalata.Ana iya amfani da shi azaman fim mai haske.Kasancewar atom na chlorine, yana da radius mafi girma na atomic fiye da na fluorine, yana hana kusantar tattarawa a cikin PTFE.Wannan yana haifar da samun ƙarancin narkewa tsakanin fluoropolymers, kusa da 210-215 ° C.PCTFE yana da juriya ga harin ta mafi yawan sinadarai da jami'an oxidizing, dukiya da aka nuna saboda kasancewar babban abun ciki na fluorine.Koyaya, yana kumbura kaɗan a cikin mahaɗan halocarbon, ethers, esters da kaushi mai kamshi.PCTFE yana da juriya ga oxidation saboda ba shi da wani atom na hydrogen.PCTFE yana nuna madaidaicin lokacin dipole saboda asymmetry na kwayoyin halitta na rukunin maimaitawarsa.Wannan lokacin dipole yana daidai da axis ɗin sarkar carbon.Aikace-aikace CTFE ya sami yawancin aikace-aikacen sa saboda manyan kaddarorin guda biyu: ƙin ruwa da kwanciyar hankali na sinadarai.Ana amfani da fina-finan PCTFE azaman kariya daga danshi.Waɗannan sun haɗa da:• shingen danshi a cikin marufi na blister na magunguna,• shamakin tururin ruwa don kare rufin phosphor a cikin fitilun lantarki (sunadarai na phosphor suna kula da danshi),• kariya daga bangarorin nunin ruwa-crystal nuni (LCD), wadanda ke kula da danshi.Saboda daidaiton sinadarai, yana aiki a matsayin shingen kariya daga sinadarai.Ana amfani da shi azaman sutura da riga-kafi don aikace-aikacen sinadarai.PCTFE kuma ana amfani da laminating sauran polymers kamar PVC, polypropylene, PETG, APET da dai sauransu Ana kuma amfani da m eyeglasses, tubes, bawuloli, sinadaran tanki liners, O-zobba, seals da gaskets.Ana amfani da PCTFE don kare abubuwan haɗin lantarki masu mahimmanci saboda kyakkyawan juriyar wutar lantarki da tsantsar ruwa.Sauran abubuwan amfani sun haɗa da da'irori masu sassauƙa na bugu da rufe wayoyi da igiyoyi.Kakin PCTFE masu ƙarancin nauyin kwayoyin halitta, mai da maiko suna samun aikace-aikacen su azaman mai ɗaukar nauyi da mai.Ana kuma amfani da su azaman gyroscope flotation waters da robobi don thermoplastics.
