Izitena zokugquma ezikhaphukhaphu kwizitofu zeglasi zinokuhlelwa ngokweendidi ezi-6 ngokwemathiriyeli yazo eyahlukileyo. Ezona zisetyenziswa kakhulu zizitena ze-silica ezikhaphukhaphu kunye nezitena zediatomite. Izitena zokugquma ezikhaphukhaphu zineengenelo zentsebenzo entle yokugquma i-thermal, kodwa ukumelana noxinzelelo lwazo, ukuxhathisa kwe-slag, kunye nokumelana nokothuka kwe-thermal akubi, ngoko ke abanako ukunxibelelana ngokuthe ngqo neglasi etyhidiweyo okanye ilangatye.
1. Izitena ze-silica ezilula. Isitena sokugquma i-silica esikhaphukhaphu yimveliso ye-insulation refractory eyenziwe kwi-silica njengeyona nto iphambili ekrwada, enomxholo we-SiO2 ongekho ngaphantsi kwe-91%. Ubuninzi bezitena zokufakelwa kwe-silica ezikhaphukhaphu yi-0.9 ~ 1.1g / cm3, kwaye i-thermal conductivity yayo sisiqingatha kuphela sezitena eziqhelekileyo ze-silica. Inokumelana nokothuka kwe-thermal, kwaye ubushushu bayo obuthambileyo phantsi komthwalo bunokufikelela kwi-1600 ℃, engaphezulu kakhulu kunezitena zokugquma udongwe. Ke ngoko, ubushushu obuphezulu bokusebenza kwezitena zokufakelwa kwe-silica zinokufikelela kwi-1550 ℃. Ayincipha kumaqondo obushushu aphezulu, kwaye inokwandiswa okuncinci. Izitena ezikhanyayo ze-silica ziveliswa ngokubanzi ngekristali yeQuartzite njengezinto ezitsha, kunye nezinto ezinokutsha ezifana ne-coke, i-anthracite, i-sawdust, njl.
2. Izitena ze-Diatomite: Xa kuthelekiswa nezinye izitena zokugquma ukukhanya, izitena ze-diatomite zine-conductivity ephantsi ye-thermal. Ubushushu bayo bokusebenza buhluka ngobunyulu. Ubushushu bokusebenza ngokuqhelekileyo bungaphantsi kwe-1100 ℃ kuba ukucutheka kwemveliso kukhulu kakhulu kumaqondo aphezulu. Izinto eziluhlaza zezitena ze-diatomite kufuneka zitshiswe kwiqondo lokushisa eliphezulu, kwaye i-silicon dioxide inokuguqulwa ibe yi-quartz. I-Lime inokongezwa kwakhona njenge-binder kunye ne-mineralizer ukukhuthaza ukuguqulwa kwe-quartz ngexesha lokudubula, okunenzuzo ekuphuculeni ukuchasana nokushisa kwemveliso kunye nokunciphisa ukuncipha kwiqondo lokushisa eliphezulu.
Ushicilelo olulandelayo siya kuqhubeka ukwazisa ulwahlulo lweisitena esilula sokugqumakwiziko leglasi. Nceda uhlale ubukele!
