Bophelong ba rona ba letsatsi le letsatsi, re atisa ho sebelisa lihlahisoa tse sa tšoaneng tsa khalase, tse kang lifensetere tsa khalase, likhalase, mamati a thellang a khalase, joalo-joalo Lihlahisoa tsa khalase li ntle ebile lia sebetsa.Lintho tse tala tsa botlolo ea khalase ke lehlabathe la quartz e le thepa e ka sehloohong e tala, 'me lisebelisoa tse ling tse thusang li qhibilihisoa hore li be boemong ba metsi ka mocheso o phahameng, ebe botlolo ea oli ea bohlokoa e kenngoa ka har'a hlobo, e pholile, e khaola, ebe e halefa. botlolo ea khalase.Hangata libotlolo tsa khalase li na le matšoao a thata, ao hape a entsoeng ka libopeho tsa hlobo.Ho bōptjoa ha libotlolo tsa khalase ho ka aroloa ka mefuta e meraro: ho phunya ka letsoho, ho phunya ka mechine le ho hlahisa extrusion ho latela mokhoa oa tlhahiso.A re shebeng ts'ebetso ea tlhahiso ea libotlolo tsa khalase.
Mokhoa oa ho hlahisa botlolo ea khalase:
1. Raw thepa preprocessing.Lisebelisoa tse ngata tse tala (lehlabathe la quartz, soda ash, limestone, feldspar, joalo-joalo) li pshatleha, lihlahisoa tse metsi li omisitsoe, 'me lihlahisoa tse nang le tšepe li sebetsanoa ho netefatsa boleng ba khalase.
2. Ho lokisetsa sehlopha.
3. Ho qhibiliha.Sehlopha sa khalase se futhumatsoa ka mocheso o phahameng (1550 ~ 1600 likhato) ka sebōping sa letamo kapa sebōpi sa letamo ho etsa khalase ea metsi e sa tšoaneng, e se nang bubble e finyellang litlhoko tsa ho bōptjoa.
4. Ho theha.Beha khalase ea metsi ka har'a hlobo ho etsa sehlahisoa sa khalase sa sebopeho se hlokahalang, ka kakaretso preform e thehoa pele, ebe preform e thehoa 'meleng oa botlolo.
5. Kalafo ea mocheso.Ka annealing, quenching le mekhoa e meng, khatello ea maikutlo, karohano ea mekhahlelo kapa crystallization ka hare ho khalase e hloekisoa kapa e hlahisoa, 'me boemo ba sebopeho sa khalase bo fetoloa.
