Opanga magalasi okhala ndi magawo awiri azipukuta zinthu zawo panthawi yopanga.Chifukwa chachikulu cha izi ndikuwonetsetsa kugwiritsidwa ntchito kwa mankhwalawa ndi kuyeretsa kwa zinthuzo, kuti mupewe kuuma kwa zinthuzo.Tiyeni tiphunzire njira zopukutira zomwe zimagwiritsidwa ntchito pokonza magalasi pansipa.
1. Chithandizo cha asidi ndi kupukuta: Kuwonongeka kwa galasi pamwamba pa asidi kumagwiritsidwa ntchito pochiza pamwamba.Asanayambe kupukuta, kupukuta lamba kumafunikanso, chifukwa kupukuta kwa asidi kumatha kuchepetsa makulidwe a galasi lokha ndipo sikungachotseretu tinthu tating'ono pagalasi.Njira yophatikizira yankho la asidi iyenera kusinthidwa ndi zida zosiyanasiyana zagalasi lamitundu iwiri.
2. Kupukuta kwamoto: Pamwamba pa chikhocho chimafewetsedwa ndikuwotchedwa ndi moto, ndipo mizere ina yozungulira ndi makwinya pamtunda imatha kuchotsedwa ndi mphamvu yamoto.Makapu ambiri agalasi osanjikiza awiri amapukutidwa ndi moto mukatha kudula, koma njira yochizira iyi imachepetsa kusalala kwa galasi pamwamba, ndipo ndikosavuta kuphulitsidwa.Zida zamagalasi zomwe zimagwiritsidwa ntchito kwambiri ndi galasi la soda ndi galasi la borosilicate.
3. Kupukuta ufa wonyezimira: Njira iyi imagwiritsa ntchito kupukuta kwa galasi pamwamba kwambiri kuti achotse zokopa, zomwe zingapangitse kuti kapuyi ikhale yotulutsa kuwala ndi refraction.Musanayambe kupukuta, zigawozo ziyenera kupukutidwa ndi lamba wa abrasive (diamondi yopera disc yokhala ndi ma meshes 400 kapena kuposa).Njirayi imagwiritsa ntchito zipangizo zambiri, ndipo zotsatira zake zabwino ndi cerium oxide (osowa padziko lapansi kupukuta ufa), koma ndondomekoyi ndi yochedwa kwambiri ndipo ndi yoyenera pazinthu zambiri zamagalasi.
