Mitundu Yaikulu Yamagalasi
· Type I - Borosilicate Glass
· Type II - Galasi Yopangidwa ndi Soda Laimu
· Type III - Soda Lime Glass
Zida zomwe zimagwiritsidwa ntchito popanga galasi zimaphatikizapo pafupifupi 70% mchenga pamodzi ndi kusakaniza kwapadera kwa soda phulusa, miyala yamchere ndi zinthu zina zachilengedwe - malingana ndi zomwe zimafunidwa mu batch.
Njira Zopangira Zotengera Zagalasi
Galasi Yophulika imadziwikanso kuti galasi lopangidwa.Popanga magalasi owumbidwa, magalasi otenthetsera kuchokera m'ng'anjo amapita kumakina omangira ndi kulowa m'mabowo momwe mpweya umakakamizika kuti upangitse khosi ndi chidebe chambiri.Akapangidwa, amadziwika kuti Parison.Pali njira ziwiri zosiyana zopangira chotengera chomaliza:
Njira Yowomba ndi Kuwomba -ntchito zotengera yopapatiza kumene parison aumbike ndi wothinikizidwa mpweya
Press & Kuwomba Njira-amagwiritsidwa ntchito popangira mbiya zazikulu zomaliza zomwe parishiyo imapangidwa ndi kukanikiza galasi pa nkhungu yopanda kanthu ndi plunger yachitsulo.
Njira Zopangira Magalasi Ophulika
Njira ya Kuwomba ndi Kuwomba -Mpweya woponderezedwa umagwiritsidwa ntchito popanga gob kukhala parison, yomwe imakhazikitsa kumapeto kwa khosi ndikupatsa gob mawonekedwe ofanana.Parishiyo amatembenuzidwira mbali ina ya makinawo, ndipo mpweya umagwiritsidwa ntchito kuuzira kuti ukhale momwe akufunira.
Press ndi Kuwomba Njira-Plunger imayikidwa poyamba, mpweya umatsatira kupanga gob kukhala parison.
Nthawi ina njirayi idagwiritsidwa ntchito ngati zotengera zapakamwa zazikulu, koma ndikuwonjezera kwa Vacuum Assist Process, zitha kugwiritsidwanso ntchito ngati kamwa yopapatiza.
Mphamvu ndi kugawa zili bwino kwambiri mu njira iyi yopangira magalasi ndipo zalola opanga kupanga "zopepuka" zinthu wamba monga mabotolo a mowa kuti asunge mphamvu.
Kukonzekera - ziribe kanthu momwe zimakhalira, zotengera zamagalasi zikapangidwa, zotengerazo zimayikidwa mu Annealing Lehr, pomwe kutentha kwawo kumabwereranso mpaka pafupifupi 1500 ° F, kenako kuchepetsedwa pang'onopang'ono mpaka pansi pa 900 ° F.
Kutenthetsanso ndi kuziziritsa pang'onopang'ono kumeneku kumathetsa nkhawa zomwe zili muzotengera.Popanda sitepe iyi, galasilo likhoza kusweka mosavuta.
Chithandizo cha Pamwamba -Kuchiza kwakunja kumagwiritsidwa ntchito pofuna kupewa abrading, zomwe zimapangitsa galasi kukhala losavuta kusweka.Chophimbacho (nthawi zambiri chimakhala chosakaniza cha polyethylene kapena tin oxide) chimapoperapo ndikuchita pamwamba pa galasi kuti apange zokutira za tin oxide.Kupaka kumeneku kumalepheretsa mabotolowo kumamatirana kuti achepetse kusweka.
Kupaka kwa Tin oxide kumagwiritsidwa ntchito ngati chithandizo chakumapeto kotentha.Pochiza kuzizira kozizira, kutentha kwa zotengerazo kumachepetsedwa kukhala pakati pa 225 ndi 275 ° F musanagwiritse ntchito.Chophimba ichi chikhoza kutsukidwa.Chithandizo cha Hot End chimagwiritsidwa ntchito musanayambe ndondomeko ya annealing.Mankhwala ogwiritsidwa ntchito motere amakhudzidwa ndi galasi, ndipo sangathe kutsukidwa.
Chithandizo cha M'kati - Internal Fluorination Treatment (IFT) ndi njira yomwe imapangitsa galasi la Type III kukhala galasi la Type II ndipo limayikidwa pagalasi kuti lisapangike pachimake.
Kuyang'anira Ubwino -Hot End Quality Inspection imaphatikizapo kuyeza kulemera kwa botolo ndikuwunika kukula kwa botolo ndi ma go no-go gauges.Pambuyo pochoka kumalo ozizira a lehr, mabotolo amadutsa pamakina oyendera magetsi omwe amazindikira zolakwika.Izi zikuphatikiza, koma sizimangokhala: kuyang'ana makulidwe a khoma, kuzindikira zowonongeka, kusanthula mawonekedwe, kuyang'anira malo osindikizira, kuyang'ana khoma lakumbali ndi kusanthula m'munsi.
