Ingxoxo ngenkqubo yokuvelisa amabhastile eglasi

Izinto ekrwada yebhola yeglasi ubukhulu becala yinkunkuma yeglasi kunye nemathiriyeli ekrwada. Ukwenza iiglasi zeglasi, okokuqala, zonke iintlobo ze-ores kufuneka zityunyuzwe, zongezwe kwi-powder, kwaye ngokokubunjwa kweglasi, zenziwe ngezinto ezidibeneyo, kwaye zihlanjwe kunye neglasi yenkunkuma kwi-ore yeglasi yokunyibilika, ukwenza. ulwelo lweglasi. Iglasi yolwelo ihamba ngetanki yokutya kwaye kufuneka inyibilikiswe ngokupheleleyo kwaye icaciswe. Inkqubo yokucacisa lelona nqanaba lobushushu liphezulu kwinkqubo yokunyibilika kweglasi (1400-1500 ℃), undoqo wenkqubo yokucacisa kukuphucula ubushushu kunye nokunciphisa i-viscosity kunye nokulungelelaniswa kwe-ejenti yokucacisa, kwelinye icala ukunciphisa i-bubble. Ukuxhathisa i-buoyancy, kwelinye icala ukwandisa umthamo we-bubble, ukukhutshwa kwe-bubble, kunye nokusika umthombo wamaqamza ahlaziyekayo. Emva kokucaciswa, ulwelo lweglasi ekugqibeleni luyaphuma luphuma kwindawo yokuphuma ukuze lwenza isitokhwe. Ubushushu bempahla, iglasi yobisi ngokuqhelekileyo yi-1150 ~ 1170 ℃, iglasi eqhelekileyo ecacileyo yi-1200 ~ 1220 ℃. Isitokhwe sichetywe kwiipelletsi phantse amaxesha angama-200 ngomzuzu. I-embryo yebhola idlula kwi-chute, umsasazi webhola, kwaye ishukunyiswa yipleyiti yokusasaza ibhola, iqengqeleka kwiifuneli ezahlukeneyo, ize iwele kwibhola eyenza umkrozo owenziwe ngeerola ezintathu ezinecala elifanayo lokujikeleza. I-embryo yebhola ijikeleza kwi-roller kwaye ukuxinezeleka kwayo komphezulu kwenza, ngokuthe ngcembe yenze ibhola yeglasi egudileyo kunye nengqukuva.
Ekugqibeleni, emva kokupholisa kunye nokukhethwa, yibhola yeglasi esiyibona yonke imihla.

Zonke iibhola zeglasi zibunjwa ngumatshini ngexesha elinye. Kukho amaqamza ambalwa ngaphakathi kweebhola zeglasi, kwaye umphezulu uya kugcina isiva, amanqaku ezinzipho kunye nefuthe elicacileyo eliveliswa ngexesha lemveliso, kodwa iibhola zigudile kwaye zingqukuva.
