Ulusi wagalasi uli ndi makhalidwe abwino kwambiri ndipo umagwiritsidwa ntchito kwambiri m'magawo ambiri. Ndi chinthu chosapangidwa ndi chitsulo chomwe chingalowe m'malo mwa chitsulo. Chifukwa cha kuthekera kwake kopanga zinthu zabwino, makampani akuluakulu opanga ulusi wagalasi akuyang'ana kwambiri kafukufuku wokhudza magwiridwe antchito apamwamba komanso kukonza bwino njira zopangira ulusi wagalasi.
1 Tanthauzo la ulusi wagalasi
Ulusi wagalasi ndi mtundu wa zinthu zopanda chitsulo zomwe zimatha kulowa m'malo mwa chitsulo ndipo zimagwira ntchito bwino kwambiri. Zimakonzedwa pokoka galasi losungunuka kukhala ulusi kudzera mu mphamvu yakunja. Uli ndi makhalidwe a mphamvu zambiri, modulus yapamwamba komanso kutalikitsa pang'ono. Kukana kutentha ndi kupsinjika, kuchuluka kwa kutentha kwakukulu, malo osungunuka kwambiri, kutentha kwake kofewa kumatha kufika 550 ~ 750 ℃, kukhazikika bwino kwa mankhwala, kosavuta kuyaka, uli ndi makhalidwe abwino kwambiri monga kukana dzimbiri, ndipo wakhala akugwiritsidwa ntchito kwambiri m'magawo ambiri.
2 Makhalidwe a ulusi wagalasi
Malo osungunuka a ulusi wagalasi ndi 680℃, malo owira ndi 1000℃, ndipo kuchuluka kwake ndi 2.4~2.7g/cm3. Mphamvu yomangirira ndi 6.3 mpaka 6.9 g/d mu mkhalidwe wokhazikika ndi 5.4 mpaka 5.8 g/d mu mkhalidwe wonyowa.Ulusi wagalasi Ili ndi chitetezo chabwino cha kutentha ndipo ndi chinthu choteteza kutentha chapamwamba kwambiri chokhala ndi chitetezo chabwino cha kutentha, chomwe chili choyenera kupanga zinthu zoteteza kutentha komanso zosapsa ndi moto.
3 Kapangidwe ka ulusi wagalasi
Galasi lomwe limagwiritsidwa ntchito popanga ulusi wagalasi ndi losiyana ndi galasi lomwe limagwiritsidwa ntchito popanga zinthu zina zagalasi. Galasi lomwe limagwiritsidwa ntchito popanga ulusi wagalasi lili ndi zinthu zotsatirazi:
(1)Galasi lamagetsi,Galasi lotchedwanso kuti galasi lopanda alkali, ndi la galasi la borosilicate. Pakati pa zipangizo zomwe zimagwiritsidwa ntchito popanga ulusi wagalasi, galasi lopanda alkali ndilo lomwe limagwiritsidwa ntchito kwambiri. Galasi lopanda alkali lili ndi mphamvu zabwino zotetezera kutentha komanso makina, ndipo limagwiritsidwa ntchito makamaka popanga ulusi wagalasi woteteza kutentha komanso ulusi wagalasi wamphamvu kwambiri, koma galasi lopanda alkali sililimbana ndi dzimbiri la inorganic acid, kotero siliyenera kugwiritsidwa ntchito m'malo okhala ndi acid. Tili ndi galasi la e-glass.kuyendayenda kwa fiberglass, galasi lamagetsinsalu yoluka ya fiberglass，ndi galasi lamagetsimphasa ya fibergrlass.
(2)Galasi la C, yomwe imadziwikanso kuti galasi lapakati pa alkali. Poyerekeza ndi galasi lopanda alkali, ili ndi mphamvu zabwino zotsutsana ndi mankhwala komanso mphamvu zamagetsi ndi makina zoipa. Kuwonjezera diboron trichloride ku galasi lapakati pa alkali kungapangitse kuti ipangemphasa ya pamwamba ya ulusi wagalasi,zomwe zili ndi makhalidwe oletsa dzimbiri. Ulusi wagalasi wapakati wopanda boron-alkali umagwiritsidwa ntchito makamaka popanga nsalu zosefera ndi nsalu zokutira.
Mpando wodulidwa ndi ulusi wa fiberglass
(3)Ulusi wagalasi wolimba kwambiri,monga momwe dzinalo likusonyezera, ulusi wagalasi wamphamvu kwambiri uli ndi mawonekedwe a mphamvu yayikulu komanso modulus yayikulu. Mphamvu yake yolumikizira ulusi ndi 2800MPa, yomwe ndi yokwera pafupifupi 25% kuposa ulusi wagalasi wopanda alkali, ndipo modulus yake yotanuka ndi 86000MPa, yomwe ndi yokwera kuposa ulusi wagalasi wa E. Kutulutsa kwa ulusi wagalasi wamphamvu kwambiri sikokwera, kuphatikiza ndi mphamvu yake yayikulu komanso modulus yayikulu, kotero nthawi zambiri imagwiritsidwa ntchito mu zida zankhondo, ndege ndi masewera ndi zina, ndipo siigwiritsidwa ntchito kwambiri m'magawo ena.
(4)Ulusi wagalasi wa AR, yomwe imadziwikanso kuti ulusi wagalasi wosagonjetsedwa ndi alkali, ndi ulusi wosapangidwa ndi zinthu zachilengedwe. Ulusi wagalasi wosagonjetsedwa ndi alkali uli ndi kukana bwino kwa alkali ndipo umatha kukana dzimbiri la zinthu zambiri za alkali. Uli ndi modulus yolimba kwambiri komanso kukana kukhudza, mphamvu yokoka komanso mphamvu yopindika. Ulinso ndi makhalidwe osayaka, kukana chisanu, kukana kutentha ndi chinyezi, kukana ming'alu, kukana kulowerera, kulimba kwa pulasitiki komanso kuumba kosavuta. Zipangizo za nthiti za konkire yolimbikitsidwa ndi ulusi wagalasi.
4 Kukonzekera ulusi wagalasi
Njira yopangiraulusi wagalasiKawirikawiri amafunika kusungunula zinthu zopangira, kenako n’kuchita kukonza ulusi. Ngati zipangidwa ngati mipira ya ulusi wagalasi kapena ndodo za fiberglass, kukonza ulusi sikungachitike mwachindunji. Pali njira zitatu zopangira ulusi wagalasi:
Njira yojambulira: njira yayikulu ndi njira yojambulira ya filament nozzle, kutsatiridwa ndi njira yojambulira ya ndodo yagalasi ndi njira yojambulira ya melt drop;
Njira yogwiritsira ntchito centrifugal: ng'oma yogwiritsira ntchito centrifugation, step centrifugation ndi horizontally porcelain disc centrifugation;
Njira yopumira: njira yopumira ndi njira yopumira nozzle.
Njira zingapo zomwe zili pamwambapa zingagwiritsidwenso ntchito pamodzi, monga kupukuta ndi zina zotero. Kukonza pambuyo kumachitika pambuyo pa ulusi. Kukonza pambuyo pa ulusi wagalasi la nsalu kumagawidwa m'magawo awiri akuluakulu otsatirawa:
(1) Pakupanga ulusi wagalasi, ulusi wagalasi wophatikizidwa usanalowedwe uyenera kukhala wofanana ndi kukula kwake, ndipo ulusi waufupi uyenera kupopedwa ndi mafuta asanasonkhanitsidwe ndikuyikidwa mabowo m'ng'oma.
(2) Kukonza kwina, malinga ndi momwe galasi lalifupi lilili komanso momwe lilili lalifupi.kuyendayenda kwa ulusi wagalasi pali njira zotsatirazi:
①Masitepe afupiafupi ogwiritsira ntchito ulusi wagalasi:
②Kukonza njira zoyendetsera ulusi wagalasi:
