Kodi firgelass ndi chiyani?
Mitengo yamagalasi imagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zawo komanso zabwino, makamaka m'makampani opanga. Kumayambiriro kwa zaka za zana la 18, azungu anazindikira kuti galasi likhoza kukhala ulusi kukhala ulusi. Bokosi la Empel Emperor Napoleon adayamba kale kukhala ndi nsalu zokongoletsera za fiberglass. Magalasi agalasi ali ndi mafilimu komanso zingwe zazifupi kapena maboti. Mafayilo agalasi amagwiritsidwa ntchito m'magawo ophatikizika, ndolo za mphira, zingwe zonyamula, etpuulin, etc. zimagwiritsidwa ntchito makamaka m'malo osapangidwe
Katundu wagalasi wagalasi ndi makina, amangopanga nsalu, komanso mtengo wotsika poyerekeza ndikaboniPangani zinthu zosankha zopangira magwiridwe antchito apamwamba. Mafuta agalasi amapangidwa ndi oxisis a silica. Mitundu yagalasi imakhala ndi katundu wabwino kwambiri monga kukhala wocheperako, mphamvu yayikulu, kuuma kotsika komanso kulemera kopepuka.
Fiber Ma politymer olimbikitsidwa amakhala ndi gulu lalikulu la mitundu yosiyanasiyana ya ulusi wagalasi, monga ulusi wamtali,ulusi wosankhidwa, mphasa yoluka, ndipoakanadulidwa, ndipo amagwiritsidwa ntchito kukonza makina opangira makina ndi chifundo cha polima. Mafuta agalasi amatha kukwaniritsa gawo loyambirira la kuchuluka, koma kufooka kungayambitse ulusi wosweka panthawi yokonzekera.
Mitundu ya galasi
Makhalidwe Akuluakulu a Fired Phatikizani izi:
Sikosavuta kuyamwa madzi:FiberKodi kutetezedwa kwamadzi ndipo sioyenera zovala, chifukwa thukuta silidzatheka, kupangitsa wolandilayo kukhala wonyowa; Chifukwa zinthu sizikhudzidwa ndi madzi, sizingakhalike.
Kulephera: Chifukwa chakusowa kwa zotayika, nsaluyo ili ndi chibadwa chochepa komanso kuchira. Chifukwa chake, amafunikira chithandizo cham'mwamba kuti aletse makwinya.
Mphamvu zazikulu:Galasi ndizolimba kwambiri, pafupifupi molimba ngati kevlar. Komabe, zifaniziro zikacheza wina ndi mnzake, zimathyola ndikupangitsa nsalu kuti ikhale yowoneka bwino.
Kutulutsa: mu mawonekedwe achidule, fiberglass ndi abwino kwambiri.
Kuchita masewera olimbitsa thupi: ulusi waluso, ndikuwapangitsa kukhala oyenera makatani.
Kutsutsa Kutentha: Mafala agalasi amakhala ndi kukana kwapamwamba, amatha kupirira kutentha mpaka 315 ° C, sakhudzidwa ndi kuwala kwa dzuwa, bulichi, mabakiteriya, alkalis.
Otengeka:Ulusi wagalasi amakhudzidwa ndi hydrofluoric acid ndi otentha phosphoric acid. Popeza fiber ndi mankhwala osokoneza bongo, ulusi wina waiwisi uyenera kusamalidwa, chifukwa chiberekero chimatha kusalimba ndipo chitha kuvalira khungu, chifukwa magolovesi amayenera kuvalidwa akamagwira fiberglass.
Kugwiritsa ntchito ulusi wagalasi
Galasi ndi zinthu zachilengedwe zomwe sizikuwotcha komanso kusungitsa pafupifupi 25% yamphamvu yake yoyambirira pa 540 ° C. Mankhwala ambiri samakhudzanso ulusi wagalasi. Inorgan fiberglass sangaumbitse kapena kuwonongeka. Magalasi agalasi amakhudzidwa ndi hydrofluoric acid, yotentha phosphoric acid ndi zinthu zamphamvu za alkaline.
Ndi zinthu zamagetsi zabwino kwambiri.Nsalu za fiberglass kukhala ndi katundu monga chinyezi chochepa, nyonga yayikulu, kukana kutentha komanso kuchepa kwa dielect komanso kumapangitsa kuti azikhala ndi zilolezo zabwino kwambiri pazoyeserera zosindikizidwa ndikupereka ma varnisashes.
