Indawo yokusebenza yesithando seglasi inzima kakhulu, futhi umonakalo wendwangu yesithando seglasi yezinto ezivimbela ukunamathela uthinteka kakhulu yizici ezilandelayo.
(1) Ukuguguleka kwamakhemikhali
Uketshezi lwengilazi ngokwalo luqukethe isilinganiso esikhulu sezingxenye ze-SiO2, ngakho-ke lune-asidi yamakhemikhali. Lapho izinto zokubopha i-oven zithintana noketshezi lwengilazi, noma ngaphansi kwesenzo sesigaba segesi-uketshezi, noma ngaphansi kwesenzo sempuphu nothuli oluhlakazekile, ukugqwala kwamakhemikhali kwalo kuba kubi kakhulu. Ikakhulukazi phansi nasodongeni oluseceleni lwebhavu, lapho kuguguleka khona uketshezi lwengilazi oluncibilikisiwe ngokuhamba kwesikhathi, ukuguguleka kwamakhemikhali kuba kubi kakhulu. Izitini zokuhlola ze-regenerator zisebenza ngaphansi kokuguguleka kokushisa okuphezulu komusi, igesi nothuli, umonakalo wamakhemikhali nawo unamandla. Ngakho-ke, lapho kukhethwa izinto zokungaguguleki, ukumelana nokugqwala kuyisici esibaluleke kakhulu okufanele sicatshangelwe. Ukungaguguleki phansi kwebhavu elincibilikisiwe kanye nokungaguguleki kodonga oluseceleni kufanele kube yi-asidi. Eminyakeni yamuva nje, izitini zochungechunge lwe-AZS ezihlanganisiwe ziyisinqumo esingcono kakhulu sezingxenye ezibalulekile zebhavu elincibilikisiwe, njengezitini ze-zirconia mullite kanye nezitini ze-zirconium corundum, ngaphandle kwalokho, kusetshenziswa nezitini ze-silicon ezisezingeni eliphezulu.
Uma kucatshangelwa isakhiwo esikhethekile sesitofu sengilazi, udonga kanye nesisekelo sebhavu kwenziwa ngezitini ezinkulu eziphikisayo esikhundleni sezitini ezincane, ngakho-ke izinto zokwakha zihlanganiswe kakhulu.
(2) Ukuhlikihla ngomshini
Ukukhuhla ngomshini ikakhulukazi ukukhuhla okunamandla kokugeleza kwengilazi encibilikisiwe, njengomphimbo wesitofu sengxenye yokuncibilika. Okwesibili ukukhuhla ngomshini kwezinto, njengembobo yokushaja izinto. Ngakho-ke, izinto ezingasetshenziswa lapha kufanele zibe namandla aphezulu omshini kanye nokumelana okuhle nokukhuhla.
(3) Isenzo sokushisa okuphezulu
Izinga lokushisa lokusebenza kwesitofu sengilazi liphezulu lifinyelela ku-1600 °C, kanti ukushintshashintsha kwezinga lokushisa kwengxenye ngayinye kuphakathi kuka-100 no-200 °C. Kufanele futhi kuqashelwe ukuthi ulwelwesi lwesitofu lusebenza ngaphansi kwezimo zokushisa okuphezulu zesikhathi eside. Izinto ezivimbela isitofu sengilazi kumele zimelane nokuguguleka kwezinga lokushisa eliphezulu, futhi akufanele zingcolise uketshezi lwengilazi.
