Isigaba 1: Ubuciko Bokuhlanganisa
Uhambo lwe-aibhodlela lengilazikuqala emnyangweni wokuhlanganisa. Lapha, kuqoqwa izintaba zesihlabathi se-silica, i-limestone, i-dolomite, i-feldspar, i-soda ash, kanye nenani elikhulu le-cullet ephinde yasetshenziswa (ingilazi ephukile) kanye nezinye izinto zokusetshenziswa zamaminerali namakhemikhali. Ngaphansi kokulawulwa kwezinhlelo ezizenzakalelayo, lezi zinto zokusetshenziswa zilinganiswa futhi zixutshwa ngokunembile, ziguqulwa zibe “i-batch” efanayo. Lesi sinyathelo sibalulekile, njengoba sinquma ngqo ubumsulwa kanye nekhwalithi yengilazi encibilikisiwe elandelayo. Ngaphezu kwalokho, ukuqinisekisa ukucaca okuphezulu kwengilazi nokukhanya, ukungcola kwensimbi ezintweni zokusetshenziswa kumele kudlule enkambisweni yokususa eqinile.
Isigaba 2: Ukuncibilika Komlilo
Iqoqo elilungisiwe lithuthwa ngama-conveyor liye endaweni yokuncibilikisa bese lifakwa esithandweni esikhulu sengilazi. Lapha, izinga lokushisa likhuphuka liye ku-1450°C kuya ku-1600°C esishisayo. Ngaphakathi kwalesi "sithando se-alchemy" esivuthayo, izinto eziwuphawuda ziyancibilika kancane kancane, zibhekane nokusabela kwamakhemikhali okuyinkimbinkimbi, ekugcineni zakha ingilazi ewuketshezi egobile, engenamabhamuza—ingilazi encibilikisiwe. Lesi sigaba siwumgogodla wenqubo yonke yokukhiqiza futhi kumele sisebenze njalo. Uma isithando sengilazi sesishisiwe, ngokuvamile sisebenza singayeki iminyaka eminingana noma ngaphezulu.
Isigaba 3: Umlingo Wokwakha
Ingilazi encibilikisiwe idluliselwa nge-feeder iye emishinini yokwakha—umshini wokwakha amabhodlela (umshini we-IS). Lesi yisinyathelo esibalulekile lapho ingilazi engenasimo iqala khona. Njengamanje, kunezinqubo ezimbili zokwakha ezijwayelekile, ezimele “ubuciko bomlingo” bemboni yanamuhla:
Eyokuqala inqubo ethi “Blow & Blow”. Le ndlela isetshenziswa kakhulu ekukhiqizeni amabhodlela anentamo encane njengamabhodlela kabhiya. Okokuqala, ingilazi encibilikisiwe igeleza ibe yisikhunta esingenalutho, lapho umoya ocindezelwe usetshenziswa khona ukwakha ukuqeda (umlomo webhodlela) kanye ne-parison yokuqala (i-preform engenalutho). Le “gob” eshisayo ekhanyayo ibe isidluliselwa kusikhunta sokugcina, lapho umoya ocindezelwe ufakwa khona futhi, uwufutha ezindongeni zangaphakathi zesikhunta ukuze kudalwe isimo sebhodlela esijwayelekile.
Okwesibili inqubo ethi “Cindezela & Blow”. Lobu ubuchwepheshe obuthuthuke kakhulu, obufanelekela kakhulu ukukhiqiza izitsha ezinomlomo obanzi njengezimbiza, futhi manje sebusetshenziswa kabanzi ekukhiqizeni amabhodlela kabhiya alula. Ngokungafani nendlela ye-Blow & Blow, uma ingilazi ingena esikhumbeni esingenalutho, i-plunger yensimbi iqala icindezele ingilazi, yakha ngesikhathi esifanayo ukuqeda ibhodlela kanye ne-parison. Ukushaya kokugcina bese kuqedela ukwakheka. Le nqubo iholela ekusatshalalisweni kobukhulu bodonga obufanayo kanye namandla aphezulu. Amabhodlela akhiqizwa ngale ndlela angaba lula ngo-20% kuya ku-50% kunalawo enziwe ngendlela yendabuko ye-Blow & Blow, okusindisa izinto zokusetshenziswa kanye nokunciphisa izindleko zokuhamba.
Isigaba 4: Ukuqeda Ukucindezeleka
Amabhodlela engilazi asanda kukhishwa emshinini wokwakha asashisa kakhulu futhi ayaphuka kalula. Kulesi sigaba, abekwe kahle ebhandeni lokuhambisa, kancane kancane enza indlela yawo ibe yi-annealing lehr ende. Ukufaka i-annealing kuyisinyathelo esibalulekile ekukhiqizweni kwengilazi. Inhloso yayo ukupholisa amabhodlela kancane kancane nangokulinganayo, kususwe ukucindezeleka kwangaphakathi okwavela ngenxa yokupholisa okusheshayo ngesikhathi sokwakheka. Ngaphandle kwale nqubo, ibhodlela lengilazi lingaphuka ngokuzenzekelayo ngenxa yomehluko omncane wokushisa noma umthelela omncane. Ngemva kokuchitha amahora amaningana edlula enkambisweni yokupholisa elawulwayo, efanayo, amabhodlela engilazi ekugcineni athola izakhiwo zawo zomzimba ezizinzile.
Isigaba 5: Ukuhlolwa Okuqinile
Esanda kuphuma emgqeni wokukhiqiza, amabhodlela engilazi kumele abhekane nochungechunge "lwamehlo" aqondayo. Imigqa yokukhiqiza yesimanje isebenzisa imishini yokuhlola ezenzakalelayo ukwenza "ukuhlolwa ngokomzimba" okuphelele ebhodleleni ngalinye: Ukuskena umzimba ukuze kutholakale amaphutha afana nokuqhekeka, amabhamuza, noma amatshe (izinhlayiya ezifakiwe); ukuhlola ubuso bokuvala bokugcina ukuze kutholakale ukuthi buyisicaba; kanye nokuhlola ukumelana kwebhodlela ekucindezelweni kwangaphakathi kanye nomthwalo oqondile. Imikhiqizo edlula lokhu kuhlolwa kuphela enezinga lokufaneleka elingu-100% eqhubekela esigabeni sokugcina sokupakisha.
Kusukela esihlabathini esivamile kuya emabhodleleni engilazi acwebezelayo, isinyathelo ngasinye sibonisa ukunemba kwesayensi yezinto ezibonakalayo kanye nokukhiqizwa kwezimboni. Kungakhathaliseki ukuthi kuyindlela ye-Blow & Blow edumile noma inqubo ye-Press & Blow emele ukuthambekela kokwenza izinto zibe lula, ubuchwepheshe obusemuva kokukhiqizwa kwamabhodlela engilazi buyaqhubeka nokukhula, businika izitsha zokupakisha zendabuko nezesimanje, ezinobungani nemvelo futhi eziphephile.
