Kodi fiberglass ndi chiyani?
Magalasi a Fiberglass amagwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wotsika komanso makhalidwe ake abwino, makamaka mumakampani opanga zinthu zosiyanasiyana. Kale m'zaka za m'ma 1700, anthu aku Europe adazindikira kuti galasi limatha kupota ulusi wopangira nsalu. Magalasi a Fiberglass ali ndi ulusi waufupi komanso ulusi waufupi. Ulusi wagalasi nthawi zambiri umagwiritsidwa ntchito pazinthu zosiyanasiyana, zinthu za rabara, malamba onyamulira, ma tarpaulins, ndi zina zotero. Ulusi waufupi umagwiritsidwa ntchito kwambiri mu nsalu zopanda ulusi, mapulasitiki aukadaulo ndi zinthu zosiyanasiyana.
Makhalidwe okongola a fiberglass ndi makina, kuphweka kwa kupanga, komanso mtengo wotsika poyerekeza ndi ulusi wa kaboni zimapangitsa kuti ikhale chinthu chomwe chimasankhidwa kwambiri pakugwiritsa ntchito zinthu zambiri. Ulusi wagalasi umapangidwa ndi ma oxide a silica. Ulusi wa fiberglass uli ndi makhalidwe abwino kwambiri a makina monga kusalimba kwambiri, mphamvu zambiri, kuuma pang'ono komanso kulemera kopepuka.
Ma polima olimbikitsidwa ndi fiberglass amakhala ndi mitundu yosiyanasiyana ya fiberglass, monga ulusi wautali, ulusi wodulidwa, mphasa zolukidwa, ndi mphasa zodulidwa, ndipo amagwiritsidwa ntchito kukonza mphamvu zamakina ndi zamtundu wa polymer composites. Fiberglass imatha kukhala ndi ma aspect ratios apamwamba, koma kufooka kungayambitse kuti ulusi usweke panthawi yokonza.
Katundu wa magalasi a fiberglass
Makhalidwe akuluakulu a fiberglass ndi awa:
Sizosavuta kuyamwa madzi: Fiberglass ndi yoletsa madzi ndipo si yoyenera zovala, chifukwa thukuta silingalowe, zomwe zimapangitsa wovala kumva kunyowa; chifukwa nsaluyo sikhudzidwa ndi madzi, sidzachepa.
Kusatanuka: Chifukwa cha kusatanuka, nsaluyo siitambasuka bwino komanso siichira msanga. Chifukwa chake, imafunika kutsukidwa pamwamba kuti isagwe.
Mphamvu Yaikulu: Fiberglass ndi yolimba kwambiri, pafupifupi yolimba ngati Kevlar. Komabe, ulusi ukagundana, umasweka ndipo zimapangitsa kuti nsaluyo iwoneke ngati yonyowa.
Kuteteza: Mwachidule, fiberglass ndi chotetezera chabwino kwambiri.
Kupindika: Ulusi umapindika bwino, zomwe zimapangitsa kuti ukhale woyenera kwambiri pa makatani.
Kukana Kutentha: Ulusi wagalasi umalimbana ndi kutentha kwambiri ndipo umatha kupirira kutentha mpaka 315°C, sukhudzidwa ndi kuwala kwa dzuwa, bleach, mabakiteriya, nkhungu, tizilombo kapena alkali.
Zingathe Kukhudzidwa: Fiberglass imakhudzidwa ndi hydrofluoric acid ndi hot phosphoric acid. Popeza ulusiwu ndi chinthu chopangidwa ndi galasi, fiberglass ina yosaphika iyenera kusamalidwa mosamala, monga zinthu zotetezera kutentha m'nyumba, chifukwa malekezero a ulusiwo ndi ofooka ndipo amatha kuboola khungu, choncho magolovesi ayenera kuvalidwa pogwira fiberglass.
Kugwiritsa ntchito fiberglass
Fiberglass ndi chinthu chosapangidwa ndi zinthu zachilengedwe chomwe sichimayaka ndipo chimasunga pafupifupi 25% ya mphamvu yake yoyambirira pa 540°C. Zambiri sizimakhudza kwambiri galasi pa fiberglass. Ulusi wosapangidwa ndi zinthu zachilengedwe sudzawunda kapena kuwonongeka. Fiberglass imakhudzidwa ndi hydrofluoric acid, hot phosphoric acid ndi zinthu zamphamvu.
Ndi chinthu chabwino kwambiri chotetezera kutentha kwa magetsi. Nsalu ya ulusi ili ndi mawonekedwe a chinyezi chambiri, mphamvu zambiri, kutentha kochepa komanso kusasinthasintha kwa dielectric, ndipo ndi chinthu chabwino kwambiri cholimbikitsira kusindikiza mbale zagalasi ndi varnish zotetezera kutentha.
Chiŵerengero champhamvu kwambiri pakati pa kulemera kwa fiberglass chimapangitsa kuti chikhale chinthu chabwino kwambiri chogwiritsidwa ntchito chomwe chimafuna mphamvu zambiri komanso kulemera kochepa. Mu mawonekedwe a nsalu, mphamvu iyi imatha kukhala yolunjika mbali imodzi kapena mbali ziwiri, zomwe zimapangitsa kuti kapangidwe kake kakhale kosinthasintha komanso mtengo wake ukhale wosiyanasiyana pamsika wamagalimoto, zomangamanga, zinthu zamasewera, ndege, zapamadzi, zamagetsi, mphamvu zapakhomo ndi zamphepo.
