Fiberglass ndi mtundu wazinthu zopanda zitsulo zomwe zimagwira ntchito bwino kwambiri.Zili ndi ubwino wambiri, monga kutchinjiriza bwino, kukana kutentha kwamphamvu, kukana kwa dzimbiri komanso mphamvu zamakina apamwamba, koma zovuta zake ndizovuta komanso zosavala bwino.Zimapangidwa ndi pyrophyllite, mchenga wa quartz, miyala yamchere, dolomite, boehmite ndi boehmite ndi kusungunuka kwapamwamba kwambiri, kujambula waya, kupukuta ulusi, kuluka nsalu ndi njira zina.The awiri a monofilament ake ndi ma microns angapo kuposa 20 microns, ofanana 1/20-1/5 wa tsitsi.Mtolo uliwonse wa fiber precursor umapangidwa ndi mazana kapena masauzande a monofilaments.Ulusi wagalasi nthawi zambiri umagwiritsidwa ntchito ngati zida zolimbikitsira muzinthu zophatikizika, zida zotchinjiriza zamagetsi, zida zotchinjiriza matenthedwe, matabwa ozungulira ndi magawo ena azachuma chadziko.
Pa Okutobala 27, 2017, mndandanda wama carcinogens wofalitsidwa ndi International Agency for Research on Cancer of the World Health Organisation adasonkhanitsidwa kuti afotokozedwe.Ulusi wazifukwa zapadera, monga galasi la E ndi "475" ulusi wagalasi, adaphatikizidwa pamndandanda wamagulu owopsa a Gulu la 2B, ndipo ulusi wamagalasi osalekeza adaphatikizidwa pamndandanda wamagulu atatu a carcinogens.
Malingana ndi mawonekedwe ndi kutalika, galasi la galasi likhoza kugawidwa kukhala ulusi wopitirira, utali wokhazikika ndi ubweya wagalasi;Malinga ndi kapangidwe ka magalasi, imatha kugawidwa kukhala alkali yaulere, yosagonjetsedwa ndi mankhwala, alkali yayikulu, alkali wapakatikati, mphamvu yayikulu, zotanuka modulus yapamwamba komanso ulusi wagalasi wosamva alkali (wosagwirizana ndi alkali).
Zida zazikulu zopangira magalasi opangira magalasi ndi: mchenga wa quartz, alumina ndi pyrophyllite, miyala yamchere, dolomite, boric acid, soda phulusa, mirabilite, fluorite, etc. Njira zopangira zikhoza kugawidwa m'magulu awiri: imodzi ndiyo kupanga mwachindunji. galasi losungunuka kukhala ulusi;Chimodzi ndi kupanga galasi losungunuka kukhala mpira wa galasi kapena ndodo ndi m'mimba mwake 20mm, ndiyeno kutentha ndi kusungunula m'njira zosiyanasiyana kuti likhale mpira wagalasi kapena ndodo yokhala ndi 3-80 μ M ya ulusi wabwino kwambiri. .Ulusi wautali wopanda malire wokokedwa ndi njira yojambulira zamakina kudzera mu mbale ya platinamu amatchedwa ulusi wagalasi wopitilira, womwe nthawi zambiri umatchedwa utali wautali.Ulusi wosiyanitsidwa wopangidwa ndi wodzigudubuza kapena kutuluka kwa mpweya umatchedwa ulusi wagalasi wokhazikika, kapena ulusi waufupi.
Ulusi wagalasi ukhoza kugawidwa m'makalasi osiyanasiyana malinga ndi kapangidwe kake, chilengedwe ndi ntchito.Malinga ndi muyezo muyezo, Class E galasi CHIKWANGWANI ndi ambiri ankagwiritsa ntchito magetsi insulating zipangizo;Kalasi S ndi ulusi wapadera.
Deta ikuwonetsa kuti kuchuluka kwa magalasi opangira magalasi aku China ndikokwera kwambiri, pomwe Jushi amawerengera 34%, kutsatiridwa ndi Taishan Glass Fiber ndi Chongqing International amatenga 17% motsatana.Shandong Fiberglass, Sichuan Weibo, Jiangsu Changhai, Chongqing Sanlei, Henan Guangyuan ndi Xingtai Jinniu adawerengera gawo laling'ono, motsatana 9%, 4%, 3%, 2%, 2% ndi 1%.
Pali njira ziwiri zopangira magalasi opangira magalasi: kawiri kupanga njira yojambulira mawaya a crucible ndi kamodzi kupanga njira yojambulira waya ya tank.
Njira yojambulira waya ya crucible ili ndi njira zambiri.Choyamba, magalasi opangira magalasi amasungunuka mu mipira ya galasi pa kutentha kwakukulu, kenaka mipira ya galasi imasungunukanso, ndipo kujambula kwa waya wothamanga kwambiri kumapangidwa kukhala ulusi wa galasi.Njirayi ili ndi zovuta zambiri, monga kugwiritsa ntchito mphamvu zambiri, kuumba kosakhazikika komanso kutsika kwa ntchito, ndipo kumathetsedwa ndi opanga magalasi akuluakulu opanga magalasi.
Njira yopangira waya ya tank ng'anjo imagwiritsidwa ntchito kusungunula pyrophyllite ndi zinthu zina zopangira magalasi mu ng'anjo.Mathovu akachotsedwa, amatengedwa kupita ku mbale ya porous drain kudzera mumsewu ndipo amakokedwa mu galasi la fiber precursor pa liwiro lalikulu.Mng'anjoyo imatha kulumikiza mbale zochucha mazana ambiri kudzera munjira zingapo kuti apange nthawi imodzi.Njirayi ndi yophweka, yopulumutsa mphamvu ndi kuchepetsa kuchepetsa, yokhazikika pakupanga, yogwira ntchito komanso yokolola zambiri, yomwe ili yabwino pakupanga kwakukulu kwadzidzidzi ndipo yakhala njira yopangira dziko lonse lapansi.Ulusi wagalasi wopangidwa ndi njirayi umapangitsa zoposa 90% za dziko lonse lapansi.
Malinga ndi lipoti la Analysis Report on Status Quo and Development Prospects of the Fiberglass Market kuyambira 2022 mpaka 2026 lotulutsidwa ndi Hangzhou Zhongjing Zhisheng Market Research Co., Ltd., pamaziko a kufalikira kwa COVID-19 ndikupitilira kuwonongeka kwa Mkhalidwe wamalonda wapadziko lonse lapansi, magalasi opangira magalasi ndi mafakitale amatha kupeza zotsatira zabwino zotere, kumbali imodzi, chifukwa cha kupambana kwakukulu kwa China pakupewa ndi kuwongolera mliri wa COVID-19, komanso kukhazikitsidwa kwake kwa msika wofunidwa m'nyumba, On. Komano, chifukwa cha kupitirizabe kukhazikitsa malamulo opangira ulusi wa magalasi pamakampani, pali mapulojekiti atsopano ocheperako ndipo achedwa.Mizere yopangira yomwe ilipo yayamba kukonza zozizira munthawi yake ndikuchedwa kupanga.Ndi kukula kwachangu kwa mafakitale akumunsi ndi mphamvu yamphepo ndi magawo ena amsika, mitundu yosiyanasiyana ya ulusi wa magalasi ndi zinthu zopangidwa zakwanitsa kukwera mitengo yambiri kuyambira kotala lachitatu, ndipo mitengo yazinthu zina zamagalasi zafika. kapena pafupi ndi mlingo wabwino kwambiri m'mbiri, Phindu lonse la malonda lapita patsogolo kwambiri.
Chingwe chagalasi chinapangidwa mu 1938 ndi kampani ya ku America;Pa Nkhondo Yachiwiri Yapadziko Lonse m'zaka za m'ma 1940, zida zamagalasi zowonjezeredwa zidayamba kugwiritsidwa ntchito m'makampani ankhondo (zigawo za akasinja, kanyumba ka ndege, zipolopolo za zida, ma vests oteteza zipolopolo, ndi zina zambiri);Kenako, ndi mosalekeza kusintha kwa ntchito chuma, kuchepa kwa mtengo kupanga ndi chitukuko cha kunsi mtsinje gulu luso zipangizo, ntchito galasi CHIKWANGWANI wakhala kukodzedwa kumunda wamba.ntchito zake kumunsi mtsinje kuphimba minda ya zomangamanga, njanji zoyendera, petrochemical, galimoto kupanga, Azamlengalenga, mphepo mphamvu m'badwo, zipangizo zamagetsi, chilengedwe uinjiniya, uinjiniya m'madzi, etc., kukhala m'badwo watsopano wa zipangizo gulu m'malo zipangizo chikhalidwe monga zitsulo, nkhuni, mwala, etc, Ndi dziko njira akutuluka makampani, amene ali ndi tanthauzo lalikulu kwa chitukuko cha dziko, kusintha ndi kukweza.
