1. Kodi galasi CHIKWANGWANI?
Ulusi wagalasiamagwiritsidwa ntchito kwambiri chifukwa cha mtengo wawo komanso katundu wabwino, makamaka mumakampani 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 zopangidwagalasi la fiberglass. Ulusi wagalasi uli 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.
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.
Ma polima opangidwa ndi galasi amapangidwa ndi gulu lalikulu la mitundu yosiyanasiyana ya ulusi wamagalasi, monga ulusi wautali, ulusi wodulidwa, mphasa zolukidwa, ndi ulusi wagalasi.mphasa 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 uduke pokonza.
1.makhalidwe a galasi CHIKWANGWANI
Makhalidwe akuluakulu a galasi fiber ndi awa:
Sizosavuta kuyamwa madzi:Ulusi wagalasi umathamangitsa madzi ndipo suyenera kuvala zovala, chifukwa thukuta silingatengeke, zomwe zimapangitsa kuti wovalayo azinyowa; chifukwa zinthu sizimakhudzidwa ndi madzi, sizingachepetse
Kusakhazikika:Chifukwa cha kusowa kwa elasticity, nsaluyo imakhala ndi kutambasula pang'ono komanso kuchira. Choncho, amafunika chithandizo chapamwamba kuti athetse makwinya.
Mphamvu Zapamwamba:Fiberglass ndi yolimba kwambiri, pafupifupi yolimba ngati Kevlar. Komabe, ulusiwo ukamatirana, umathyoka ndipo nsaluyo imaoneka yonyezimira.
Insulation:Mwachidule cha fiberglass, fiberglass ndi insulator yabwino kwambiri.
Kuthamanga:Ulusiwo umayenda bwino, kuwapangitsa kukhala abwino kwa makatani.
Kulimbana ndi Kutentha:Zingwe zamagalasi zimakhala ndi kutentha kwakukulu, zimatha kupirira kutentha mpaka 315 ° C, sizimakhudzidwa ndi kuwala kwa dzuwa, bleach, mabakiteriya, nkhungu, tizilombo kapena alkalis.
Zotheka:Ulusi wagalasi umakhudzidwa ndi hydrofluoric acid ndi hot phosphoric acid. Popeza ulusiwu ndi wopangidwa ndi galasi, ulusi wina wagalasi uyenera kusamaliridwa mosamala, monga zida zotchingira m'nyumba, chifukwa malekezero ake ndi osalimba ndipo amatha kuboola pakhungu, motero magolovesi ayenera kuvala pogwira magalasi a fiberglass.
3. Njira yopanga magalasi fiber
Galasi CHIKWANGWANIndi ulusi wopanda zitsulo womwe umagwiritsidwa ntchito kwambiri ngati mafakitale. Nthawi zambiri, zopangira zopangira magalasi zimaphatikizanso mchere wambiri komanso mankhwala opangidwa ndi anthu, zigawo zazikulu ndi mchenga wa silika, miyala yamchere ndi phulusa la soda.
Mchenga wa silika umagwira ntchito ngati galasi, pomwe phulusa la soda ndi miyala yamchere zimathandiza kuchepetsa kutentha. Kutsika kocheperako kwa kukulitsa kwamafuta kuphatikiza ndi kutsika kwamafuta otsika poyerekeza ndi asibesitosi ndi ulusi wachilengedwe kumapangitsa fiberglass kukhala chinthu chokhazikika chomwe chimachotsa kutentha mwachangu.
Ulusi wagalasiamapangidwa ndi kusungunuka kwachindunji, komwe kumaphatikizapo njira monga kusakaniza, kusungunuka, kupota, kuyanika, kuyanika, ndi kuyika. Gululo ndilo gawo loyamba la kupanga magalasi, momwe zinthu zakuthupi zimasakanizidwa bwino ndipo zosakaniza zimatumizidwa ku ng'anjo kuti zisungunuke pa kutentha kwakukulu kwa 1400 ° C. Kutentha kumeneku ndi kokwanira kutembenuza mchenga ndi zinthu zina kukhala zosungunuka; galasi losungunuka limalowa mu makina oyeretsera ndipo kutentha kumatsika kufika 1370 ° C.
Panthawi yopota ulusi wagalasi, magalasi osungunuka amatuluka m'manja ndi mabowo abwino kwambiri. Mbale ya liner imatenthedwa pakompyuta ndipo kutentha kwake kumayendetsedwa kuti mukhale ndi viscosity nthawi zonse. Jeti yamadzi idagwiritsidwa ntchito kuziziritsa ulusiwo pamene imatuluka m'manja pa kutentha pafupifupi 1204 ° C.
Mtsinje wotuluka wa galasi losungunuka umakokedwa mwamakina kukhala ulusi wokhala ndi ma diameter kuyambira 4 μm mpaka 34 μm. Kuthamanga kumaperekedwa pogwiritsa ntchito mphepo yothamanga kwambiri ndipo galasi losungunuka limakokedwa mu filaments. Pamapeto pake, zokutira zamafuta zamafuta, zomangira ndi ma coupling agents zimagwiritsidwa ntchito ku filaments. Kupaka mafuta kumathandiza kuteteza filaments kuti isapse pamene imasonkhanitsidwa ndikuponyedwa m'matumba. Pambuyo poyesa, ulusiwo umauma mu uvuni; ulusiwo umakhala wokonzeka kukonzedwanso kukhala ulusi wodulidwa, ulusi kapena ulusi.
4.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 fiberglasskukhala 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 oteteza.
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 yapawiri, kulola kusinthasintha kwa mapangidwe ndi mtengo wa ntchito zosiyanasiyana pamsika wamagalimoto, zomangamanga, katundu wamasewera, ndege, zam'madzi, zamagetsi, Kunyumba ndi mphamvu zamphepo.
Amagwiritsidwanso ntchito popanga zida zomangika, matabwa osindikizira ndi zinthu zina zapadera. Kupanga kwapachaka kwa magalasi opangira magalasi ndi pafupifupi matani 4.5 miliyoni, ndipo opanga kwambiri ndi China (60% ya msika), United States ndi European Union.
