1. Kodi ulusi wagalasi ndi chiyani?
Ulusi wagalasiamagwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wotsika komanso makhalidwe ake abwino, makamaka m'makampani opanga zinthu zosiyanasiyana. Kale kwambiri m'zaka za m'ma 1700, anthu aku Europe anazindikira kuti galasi likhoza kupota ulusi wolukira. Bokosi la Mfumu ya ku France Napoleon linali kale ndi nsalu zokongoletsera zopangidwa ndifiberglassUlusi wagalasi uli ndi ulusi waufupi komanso ulusi waufupi kapena ma floc. Ulusi wagalasi umagwiritsidwa ntchito kwambiri mu zinthu zopangidwa ndi zinthu zosiyanasiyana, zinthu zopangidwa ndi rabara, malamba onyamulira, ma tarpaulins, ndi zina zotero. Ulusi waufupi umagwiritsidwa ntchito makamaka mu nsalu zopanda ulusi, mapulasitiki aukadaulo ndi zinthu zopangidwa ndi zinthu zosiyanasiyana.
Ulusi wagalasi ndi wokongola komanso wopangidwa ndi makina, wosavuta kupanga, komanso wotsika mtengo poyerekeza ndiulusi wa kaboniPangani kuti ikhale chinthu chomwe chimasankhidwa kuti chigwiritsidwe ntchito popanga zinthu zosiyanasiyana. Ulusi wagalasi umapangidwa ndi ma oxide a silica. Ulusi wagalasi uli ndi zinthu zabwino kwambiri monga kusalimba kwambiri, mphamvu zambiri, kuuma pang'ono komanso kulemera kopepuka.
Ma polima olimbikitsidwa ndi ulusi wagalasi amakhala ndi mitundu yosiyanasiyana ya ulusi wagalasi, monga ulusi wautali, ulusi wodulidwa, mphasa zolukidwa, ndimphasa zodulidwa za ulusi, ndipo amagwiritsidwa ntchito kukonza mphamvu za makina ndi za tribological za ma polymer composites. Ulusi wagalasi ukhoza kukhala ndi ma aspect ratios apamwamba, koma kufooka kungayambitse ulusi kusweka panthawi yokonza.
1. makhalidwe a ulusi wagalasi
Makhalidwe akuluakulu a ulusi wagalasi ndi awa:
Kumwa madzi sikophweka:Ulusi wagalasi umaletsa madzi ndipo suyenera zovala, chifukwa thukuta silingalowe, zomwe zimapangitsa wovala kumva kunyowa; chifukwa nsaluyo sikhudzidwa ndi madzi, sidzachepa
Kusasinthasintha:Chifukwa cha kusowa kwa kusinthasintha, nsaluyo siitambasuka bwino komanso siichira msanga. Chifukwa chake, amafunika kutsukidwa pamwamba kuti asakwinyike.
Mphamvu Yaikulu:Fiberglass ndi yolimba kwambiri, pafupifupi yolimba ngati Kevlar. Komabe, ulusi ukagundana, umasweka ndipo zimapangitsa kuti nsaluyo iwoneke ngati yonyowa.
Kutchinjiriza:Mwachidule, fiberglass ndi chotetezera kutentha chabwino kwambiri.
Kulephera:Ulusiwo umakulungidwa bwino, zomwe zimapangitsa kuti ukhale woyenera kwambiri pa makatani.
Kukana Kutentha:Ulusi wagalasi umalimbana ndi kutentha kwambiri, umatha kupirira kutentha mpaka 315°C, sukhudzidwa ndi kuwala kwa dzuwa, bleach, mabakiteriya, nkhungu, tizilombo kapena alkali.
Wosakhazikika:Ulusi wagalasi umakhudzidwa ndi hydrofluoric acid ndi hot phosphoric acid. Popeza ulusiwu ndi chinthu chopangidwa ndi galasi, ulusi wina wosaphika wagalasi uyenera kusamalidwa mosamala, monga zinthu zotetezera kutentha m'nyumba, chifukwa malekezero a ulusiwo ndi ofooka ndipo amatha kuboola khungu, choncho magolovesi ayenera kuvalidwa pogwira fiberglass.
3. Njira yopangira ulusi wagalasi
Ulusi wagalasindi ulusi wosakhala wachitsulo womwe umagwiritsidwa ntchito kwambiri pakali pano ngati zinthu zamafakitale. Kawirikawiri, zinthu zoyambira zopangira ulusi wagalasi zimaphatikizapo mchere wachilengedwe ndi mankhwala opangidwa ndi anthu, zigawo zazikulu ndi mchenga wa silika, miyala yamwala ndi phulusa la soda.
Mchenga wa silika umagwira ntchito ngati galasi lopangira zinthu, pomwe phulusa la soda ndi miyala yamchere zimathandiza kuchepetsa kutentha kosungunuka. Kuchuluka kochepa kwa kutentha komwe kumaphatikizidwa ndi kutentha kochepa poyerekeza ndi asbestos ndi ulusi wachilengedwe kumapangitsa fiberglass kukhala chinthu chokhazikika chomwe chimachotsa kutentha mwachangu.
Ulusi wagalasiZimapangidwa ndi kusungunuka mwachindunji, komwe kumaphatikizapo njira monga kuphatikiza, kusungunula, kupota, kuphimba, kuumitsa, ndi kulongedza. Gululi ndi momwe magalasi amapangira, momwe kuchuluka kwa zinthuzo kumasakanizidwira bwino kenako chisakanizocho chimatumizidwa ku ng'anjo kuti chisungunuke pa kutentha kwakukulu kwa 1400°C. Kutentha kumeneku ndikokwanira kusintha mchenga ndi zosakaniza zina kukhala zosungunuka; galasi losungunuka limalowa mu choyeretsera ndipo kutentha kumatsika kufika pa 1370°C.
Pakuzungulira ulusi wagalasi, galasi losungunuka limatuluka kudzera mu chikwama chokhala ndi mabowo opyapyala kwambiri. Chikwama cha liner chimatenthedwa ndi magetsi ndipo kutentha kwake kumayendetsedwa kuti kukhalebe kolimba nthawi zonse. Madzi oyenda pansi amagwiritsidwa ntchito kuziziritsa ulusiwo pamene ukutuluka mu chikwamacho pa kutentha kwa pafupifupi 1204°C.
Madzi otuluka a galasi losungunuka amakokedwa ndi makina mu ulusi wokhala ndi mainchesi kuyambira 4 μm mpaka 34 μm. Kupsinjika kumaperekedwa pogwiritsa ntchito chozungulira champhamvu ndipo galasi losungunuka limakokedwa mu ulusi. Pa gawo lomaliza, zokutira za mankhwala za mafuta, zomangira ndi zolumikizira zimagwiritsidwa ntchito pa ulusi. Mafuta amathandiza kuteteza ulusiwo kuti usawonongeke pamene ukusonkhanitsidwa ndikukulungidwa m'mapaketi. Pambuyo poika kukula, ulusiwo umaumitsidwa mu uvuni; ulusiwo umakhala wokonzeka kukonzedwanso kukhala ulusi wodulidwa, mayendedwe kapena ulusi.
4.kugwiritsa ntchito ulusi wagalasi
Galasi la Fiberglass ndi chinthu chosapangidwa ndi zinthu zachilengedwe chomwe sichimayaka ndipo chimasunga pafupifupi 25% ya mphamvu yake yoyambirira pa 540°C. Mankhwala ambiri sakhudza kwambiri ulusi wagalasi. Fiberglass yosapangidwa ndi zinthu zachilengedwe siidzawuma kapena kuwonongeka. Ulusi wagalasi umakhudzidwa ndi hydrofluoric acid, hot phosphoric acid ndi zinthu zamphamvu za alkaline.
Ndi chinthu chabwino kwambiri chotetezera kutentha kwa magetsi.Nsalu zagalasiali ndi zinthu monga kuyamwa chinyezi pang'ono, mphamvu zambiri, kukana kutentha komanso kusasinthasintha kwa dielectric, zomwe zimapangitsa kuti akhale othandizira bwino kwambiri pama board osindikizidwa komanso ma varnish oteteza 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.
Amagwiritsidwanso ntchito popanga zinthu zopangidwa ndi matabwa, ma circuit board osindikizidwa ndi zinthu zosiyanasiyana zapadera. Kupanga ulusi wagalasi padziko lonse lapansi pachaka ndi pafupifupi matani 4.5 miliyoni, ndipo opanga akuluakulu ndi China (60% ya gawo la msika), United States ndi European Union.
