I-China Izithako ezinhle kakhulu zokuvikela izitini ze-silica ezingashisi umlilo ezivela efektri nabakhiqizi abathengisa efektri | Rongsheng

Isitini esiphikisayo se-silica siyamelana ne-asidi futhi sinokumelana okuhle nokuguguleka kwe-asidi. Ukumelana kwezitini ze-slica ngaphansi komthwalo kufika ku-1640~1690℃, izinga lokushisa lokuqala lokuthambisa elibonakalayo lingu-1620~1670℃ kanti ubuningi bangempela bungu-2.35g/cm3. Isitini somlilo se-silicon singasebenza ekushiseni okuphezulu isikhathi eside futhi sigcine ukuqina komthamo ngaphandle kokuguqulwa. Isitini esiphikisayo se-silicon siqukethe okuqukethwe okungaphezu kuka-94% we-SiO2. Isitini esiphikisayo sinamandla aphezulu okushisa aphezulu kanye nokumelana nokushaqeka okuphansi kokushisa. Isitini somlilo se-silica senziwe nge-silica ore yemvelo njengento eluhlaza, sengezwe i-mineralizer efanelekile yokukhuthaza i-quartz emzimbeni oluhlaza oguqulwe waba yi-tridymite futhi sishiswa kancane kancane ekushiseni okungu-1350~1430℃ emkhathini ophansi. Lapho kushisa kufika ku-1450℃, kubalwa u-1.5~2.2% wokwanda komthamo ophelele. Lokhu kwandiswa ngemva kokwandiswa kuzokwenza ukusika okuhlangene kuvaliwe futhi kuqinisekise ukuthi ukwakhiwa kugcina umoya ungangeni kahle kanye namandla esakhiwo.

Izakhiwo Zezitini Zomlilo Ze-Silica

• Ukumelana okuhle nokuguguleka kwe-asidi,
• Amandla okushisa aphezulu,
• Ukuqina okuphezulu kokungazweli: 1690~1710°C,
• I-RUL Ephakeme: cishe i-1620-1670℃,
• Ukuqina kwevolumu ekushiseni okuphezulu,
• Ukumelana okuhle nokushaqeka kokushisa.

Ukwakheka Kwezitini Zomlilo Ze-Silica

Ibhlogo lomlilo le-silicon liyisitini esiphikisayo esinokuqukethwe kwe-silica okungaphezu kuka-93%, i-tridymite engu-50%-80%, i-cristobalite engu-10%-30%, i-quartz kanye nesigaba sengilazi esingu-10%-30%, cishe u-5%-15%. Ukwakheka kwezitini ze-silicate ikakhulukazi yi-quartz eyisikali kanye ne-quartz, kanye nenani elincane le-quartz kanye ne-vitreous. I-quartz eyisikali, i-quartz eyisikali kanye ne-quartz eseleyo ishintsha kakhulu ngevolumu ngenxa yokushintsha kwesimo sekristalu ekushiseni okuphansi, ngakho-ke ukuzinza kokushisa kwesitini esiphikisayo se-silicate kubi ekushiseni okuphansi. Enqubweni yokusebenzisa, ukushisa nokubanda okungaphansi kuka-800 ℃ kuya kancane, ukuze kugwenywe imifantu. Ngakho-ke akufanele kube ngaphansi kuka-800 ℃ ukugxuma kwezinga lokushisa lesitofu.

Inqubo Yokukhiqiza Izitini Zomlilo We-Silica

Izitini zomlilo ze-silicate zenziwe nge-quartzite enenani elincane le-mineralizing agent. Uma zishiswa ekushiseni okuphezulu, ukwakheka kwezitini ze-silica refractory mineral composition kwakhiwa yi-scale quartz, i-quartzite quartz, ingilazi nezinye izicubu zesigaba esiyinkimbinkimbi ezakhiwe ekushiseni okuphezulu, kanti okuqukethwe yi-AiO2 kungaphezu kwama-93%. Phakathi kwezitini ze-silica ezishiswa kangcono, okuqukethwe yi-scale quartz kuphakeme kakhulu, okubalwa ku-50% ~ 80%. I-cristobalit yalandela, okubalwa ku-10% kuya ku-30% kuphela. Okuqukethwe yi-quartz kanye nesigaba sengilazi kuyashintshashintsha phakathi kuka-5% no-15%.

Ukusetshenziswa Kwezitini Zomlilo Ze-Silica

Izitini zomlilo ze-silica zisetshenziswa kakhulu njengezinto zokuphikisa udonga oluvikelayo lwegumbi lokuphekela kanye ne-combustor kuhhavini we-coke, igumbi lokuvuselela kanye nephakethe le-slag esithandweni esivulekile sokwenza insimbi, isithando somgodi wokucwilisa kanye nesithando sokuncibilikisa ingilazi, kanye nenye indawo yokuthwala isisindo kanye nengaphezulu kuhhavini wokushisa we-ceramic. Izitini ze-silicate zingasetshenziswa futhi endaweni yokuthwala isisindo ekushiseni okuphezulu kanye nengaphezulu kwesithando esivulekile se-acid.
