Kodi fiberglass ndi chiyani?
Magalasi a fiberglass amagwiritsidwa ntchito kwambiri chifukwa cha mtengo wake komanso katundu wabwino, makamaka m'makampani opanga zinthu.Kale kwambiri m’zaka za m’ma 1800, anthu a ku Ulaya anazindikira kuti magalasi amatha kuwomba kukhala ulusi woluka.Fiberglass ili ndi ulusi komanso ulusi wamfupi kapena flocs.Ulusi wagalasi umagwiritsidwa ntchito kwambiri muzinthu zophatikizika, zinthu za rabala, malamba onyamula katundu, ma tarpaulins, ndi zina zambiri. Zingwe zazifupi zimagwiritsidwa ntchito makamaka muzovala zopanda nsalu, mapulasitiki aumisiri ndi zida zophatikizika.
Fiberglass yowoneka bwino komanso yamakina, kupanga kosavuta, komanso kutsika mtengo poyerekeza ndi kaboni fiber imapangitsa kukhala chinthu chofunikira kwambiri pakugwiritsa ntchito kwamagulu ambiri.Ulusi wagalasi umapangidwa ndi oxides wa silika.Magalasi a fiberglass ali ndi zida zabwino zamakina monga kukhala wocheperako, mphamvu zambiri, kuuma pang'ono komanso kulemera pang'ono.
Ma polima olimba a Fiberglass amakhala ndi gulu lalikulu lamitundu yosiyanasiyana ya magalasi a fiberglass, monga ulusi wautali, ulusi wodulidwa, mphasa zolukidwa, ndi mphasa zodulidwa, ndipo amagwiritsidwa ntchito kupititsa patsogolo makina ndi tribological ma composites a polima.Magalasi a fiberglass amatha kukhala ndi mawonekedwe apamwamba kwambiri, koma brittleness imatha kupangitsa kuti ulusi usweke pokonza.
Mphamvu za fiberglass
Makhalidwe akuluakulu a fiberglass ndi awa:
Osati zosavuta kuyamwa madzi: Fiberglass ndi madzi oletsa madzi ndipo si oyenera zovala, chifukwa thukuta silingatengedwe, zomwe zimapangitsa kuti wovalayo azinyowa;chifukwa zinthu sizimakhudzidwa ndi madzi, sizingachepetse.
Kusakhazikika: Chifukwa cha kusowa kwa kukhuthala, nsaluyo imakhala ndi kutambasula pang'ono komanso kuchira.Choncho, iwo amafuna pamwamba mankhwala kukana makwinya.
Mphamvu Zapamwamba: Fiberglass ndi yamphamvu kwambiri, pafupifupi yamphamvu ngati Kevlar.Komabe, ulusiwo ukamatirana, umathyoka ndipo nsaluyo imaoneka yonyezimira.
Insulation: Mwachidule cha fiberglass, fiberglass ndi insulator yabwino kwambiri.
Drapability: Ulusiwo umayenda bwino, kuwapangitsa kukhala abwino kwa makatani.
Kulimbana ndi Kutentha: Ulusi wagalasi umalimbana ndi kutentha kwambiri ndipo ukhoza kupirira kutentha mpaka 315 ° C, sukhudzidwa ndi kuwala kwa dzuwa, bleach, mabakiteriya, nkhungu, tizilombo kapena alkalis.
Zotheka: Fiberglass imakhudzidwa ndi hydrofluoric acid ndi hot phosphoric acid.Popeza ulusiwu ndi wopangidwa ndi magalasi, magalasi ena opangira magalasi opangira magalasi ayenera kusamaliridwa mosamala, monga zida zotchingira m'nyumba, chifukwa malekezero ake ndi osalimba ndipo amatha kuboola pakhungu, motero magolovesi amayenera kuvala pogwira magalasi a fiberglass.
Kugwiritsa ntchito fiberglass
Fiberglass ndi zinthu zakuthupi zomwe siziwotcha ndipo zimasunga pafupifupi 25% ya mphamvu yake yoyamba pa 540 ° C.Ambiri amakhala ndi magalasi ochepa pa fiberglass.Ulusi wachilengedwe sudzawumba kapena kuwonongeka.Fiberglass imakhudzidwa ndi hydrofluoric acid, hot phosphoric acid ndi zinthu zamphamvu.
Ndizinthu zabwino kwambiri zotetezera magetsi.Nsalu ya fiber imakhala ndi mawonekedwe a chinyezi chambiri, mphamvu yayikulu, kutentha pang'ono komanso kutsika kwa dielectric pafupipafupi, ndipo ndi njira yabwino yolimbikitsira kusindikiza mbale zamagalasi ndi ma varnish otsekera.
Kuchuluka kwa mphamvu ndi kulemera kwa fiberglass kumapangitsa kukhala chinthu chabwino kwambiri pamapulogalamu omwe amafunikira mphamvu zambiri komanso kulemera kochepa.Mu mawonekedwe a nsalu, mphamvu iyi ikhoza kukhala yosagwirizana kapena ya bidirectional, kulola kusinthasintha kwa mapangidwe ndi mtengo wa ntchito zosiyanasiyana pamsika wamagalimoto, zomangamanga, katundu wamasewera, ndege, zam'madzi, zamagetsi, Kunyumba ndi mphamvu zamphepo.
