Zida zomwe zimagwiritsidwa ntchito popanga galasi zimaphatikizapo pafupifupi 70% mchenga pamodzi ndi kusakaniza kwapadera kwa soda phulusa, miyala ya laimu ndi zinthu zina zachilengedwe - malingana ndi zomwe zimafunidwa mu batch.
Mukapanga galasi la soda laimu, galasi lophwanyidwa, lopangidwanso, kapena cullet, ndi chinthu china chofunika kwambiri.Kuchuluka kwa cullet komwe kumagwiritsidwa ntchito mu gulu la galasi kumasiyana.Cullet imasungunuka pa kutentha kochepa komwe kumachepetsa kugwiritsa ntchito mphamvu komanso kumafuna zochepa zopangira.
Magalasi a Borosilicate sayenera kubwezeretsedwanso chifukwa ndi galasi lopanda kutentha.Chifukwa cha kutentha kwake, galasi la borosilicate silingasungunuke pa kutentha komweko monga galasi la Soda laimu ndipo lidzasintha kukhuthala kwamadzimadzi mu ng'anjo panthawi yosungunukanso.
Zida zonse zopangira galasi, kuphatikizapo cullet, zimasungidwa m'nyumba ya batch.Kenako amapatsidwa mphamvu yokoka m'malo oyezera ndi kusanganikirana ndipo pamapeto pake amakwezedwa kukhala ma batch hopper omwe amapereka ng'anjo zamagalasi.
Njira Zopangira Zotengera Zagalasi:
Galasi Yophulika imadziwikanso kuti galasi lopangidwa.Popanga magalasi owumbidwa, magalasi otenthetsera kuchokera ku ng'anjo amalunjikitsidwa 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 Zopangira Magalasi Ophulika
Njira Yowomba ndi Kuwomba - mpweya woponderezedwa umagwiritsidwa ntchito kupanga 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 and Blow Process- 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 pakamwa pang'ono.
Mphamvu ndi kugawa zili bwino kwambiri mu njira iyi yopangira magalasi ndipo zalola opanga kuti "akhale opepuka" 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 - chithandizo chakunja chimagwiritsidwa ntchito pofuna kupewa abrading, zomwe zimapangitsa galasi kukhala losavuta kusweka.Chophimbacho (kawirikawiri 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 matenda ozizira, 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 mtundu wa III kukhala galasi la Type II ndipo limayikidwa pagalasi kuti lisatuluke.
Kuyang'anira Ubwino - Kuyang'ana Kwabwino Kwambiri Kumaphatikizapo 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.
