Kodi fiberglass ndi chiyani?

Ulusi wagalasi 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.Bokosi la Mfumu ya ku France Napoleon linali kale ndi nsalu zokongoletsera zopangidwa ndi fiberglass.Ulusi wagalasi uli ndi ulusi komanso ulusi wamfupi kapena flocs.Ulusi wagalasi umagwiritsidwa ntchito kwambiri muzinthu zophatikizika, zopangidwa ndi mphira, malamba otumizira, ma tarpaulins, ndi zina zambiri. Zingwe zazifupi zimagwiritsidwa ntchito makamaka mumphasa zosalukidwa, mapulasitiki a uinjiniya ndi zida zophatikizika.

Galasi fiber imakhala yowoneka bwino komanso yamakina, yosavuta kupanga, komanso mtengo wotsika poyerekezacarbon fiberipangitseni kukhala chinthu chosankhidwa pamapulogalamu apakompyuta apamwamba kwambiri.Ulusi wagalasi umapangidwa ndi oxides wa silika.Ulusi wagalasi uli ndi zida zabwino zamakina monga kukhala wocheperako, mphamvu zambiri, kuuma pang'ono komanso kulemera pang'ono.

Glass fiber ma polima olimbikitsidwa amakhala ndi gulu lalikulu lamitundu yosiyanasiyana ya ulusi wamagalasi, monga ulusi wautali,ulusi wodulidwa, mphasa zoluka, ndimphasa za zingwe zodulidwa, ndipo amagwiritsidwa ntchito kukonza makina ndi tribological katundu wa ma polima composites.Ulusi wagalasi ukhoza kukhala ndi mawonekedwe apamwamba kwambiri, koma brittleness imatha kupangitsa kuti ulusi usweke pokonza.

galasi CHIKWANGWANI katundu

Makhalidwe akuluakulu a galasi fiber ndi awa:

Sizosavuta kuyamwa madzi:Glass fiberimachotsa madzi ndipo sichiyenera kuvala zovala, chifukwa thukuta silingatengeke, 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, amafunika chithandizo chapamwamba kuti athetse makwinya.

Mphamvu Zapamwamba:Fiberglass ndi wamphamvu kwambiri, pafupifupi wamphamvu 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.

Kukana Kutentha: Ulusi wagalasi uli ndi kutentha kwakukulu, ukhoza kupirira kutentha mpaka 315 ° C, sukhudzidwa ndi kuwala kwa dzuwa, bleach, mabakiteriya, nkhungu, tizilombo kapena alkalis.

Zotheka:Ulusi wagalasi amakhudzidwa ndi hydrofluoric acid ndi hot phosphoric acid.Popeza ulusiwu ndi wopangidwa ndi magalasi, ulusi wina wagalasi uyenera kusamaliridwa mosamala, monga zida zotsekera m'nyumba, chifukwa malekezero a ulusiwo ndi osalimba ndipo amatha kuboola pakhungu, motero magolovesi ayenera kuvala pogwira magalasi a fiberglass.

Kugwiritsa ntchito galasi fiber

Fiberglass ndi zinthu zakuthupi zomwe siziwotcha ndipo zimasunga pafupifupi 25% ya mphamvu yake yoyamba pa 540 ° C.Mankhwala ambiri sakhudza kwambiri ulusi wagalasi.Inorganic fiberglass sichingawumbe kapena kuwonongeka.Ulusi wagalasi umakhudzidwa ndi hydrofluoric acid, hot phosphoric acid ndi zinthu zamphamvu zamchere.

Ndizinthu zabwino kwambiri zotetezera magetsi.Nsalu za fiberglass kukhala ndi zinthu monga kuyamwa kwa chinyezi chochepa, mphamvu zambiri, kukana kutentha ndi kutsika kwa dielectric nthawi zonse, zomwe zimawapangitsa kukhala olimbikitsira bwino mapepala osindikizira ndi ma varnish.
