Izitini ezingasindi zokufakelwa kwezimpawu ze-kilns zengilazi zingahlukaniswa izigaba ezi-6 ngokuya ngezinto zazo ezihlukile eziluhlaza. Abasetshenziswa kabanzi kakhulu bayizitini ezingasindi ze-silica kanye nezitini ze-diatomite. Izitini ezingasindi kokufakwa kwezitsu ezingezinzuzo zokusebenza okuhle kokufakwa kwe-inval, kepha ukumelana kwabo kwengcindezi, ukumelana kwe-slag, nokumelana nokushaqeka okushisayo kumpofu, ngakho-ke ngeke bakwazi ukuxhumana ngqo nengilazi ebilisiwe noma ilangabi.
1. Izitini ze-silica ezingasindi. Isitini esikhanyayo se-silica se-Silica ngumkhiqizo ovusekayo wokufakelwa okwenziwe kusuka ku-silica njengento ebaluleke kakhulu ebonakalayo, ngokuqukethwe kwe-SIO2 kungaphansi kwama-91%. Ubuningi be-Lightweight Belica Insulation Brick yi-0.99 ~ 1.1g / cm3, kanye nokuphakelayo kwalo okushisayo kungungxenye kuphela yezitini ezijwayelekile ze-silica. Inokumelana okuhle okwethusayo, futhi izinga lokushisa lawo lokuthambisa ngaphansi komthwalo lingafinyelela ku-1600 ℃, eliphakeme kakhulu kunalobo bobukho bezitini. Ngakho-ke, izinga lokushisa elisebenzayo le-Silica Insulation Brick lingafinyelela ku-1550 ℃. Akunciphisi emazingeni okushisa aphezulu, futhi kunokwanda okuncane. Isitini esikhanyayo se-silica ngokuvamile sikhiqizwa nge-crystalline quartzite njengento eluhlaza, nezinto ezivuthayo ezifana ne-coke, i-anthracite, i-sawdust, njll.
2 Izinga lokushisa layo liyahlukahlukana. Ukushisa kwayo kokusebenza ngokuvamile kungaphansi kwe-1100 ℃ ngoba i-shrinkage yomkhiqizo inkulu kakhulu emazingeni okushisa aphezulu. Izinto ezivuthiwe ze-diatomite brick zidinga ukuxoshwa endaweni yokushisa ephakeme, futhi i-silicon dioxide ingaguqulwa ibe yi-quartz. I-Lime ingangezwa futhi njenge-binder ne-minelizer ukukhuthaza ukuguqulwa kwe-quartz ngesikhathi sokudubula, okuzuzisa ukuthuthukisa ukumelana nokushisa komkhiqizo nokunciphisa ukushwabana kwamazinga okushisa aphezulu.
Umagazini olandelayo sizoqhubeka nokwethula ukuhlukaniswa kweIzitini ezingasindiOkwesikhumba sengilazi. Sicela uhlale ubukele!
