Qashinka adag ee warshadaha ee Shiinaha ayaa inta badan ah dabada, dambaska duulista, dhuxusha gangue, slag dhalaalinta, slag dhuxusha lagu shido iyo gypsum-ka desulfurization. Diyaarinta agabka dhismaha ee laga helo qashinka adag ayaa soo jiidatay dareen badan. Cilmi-baarayaashu waxay horumariyeen heerka isticmaalka dhamaystiran ee qashinka adag ee warshadaha agabka dhismaha iyada oo loo marayo horumarinta iyo cilmi-baarista iyo horumarinta qalabka iyo tiknoolajiyada. Isla mar ahaantaana, dalal kala duwan ayaa soo saaray sharciyo iyo qawaaniin taageeraya si loo kiciyo xiisaha shirkadaha ee isticmaalka qashinka adag, sidaas darteedna waxay hagaajiyaan saameynta qashinka adag ee warshadaha ee deegaanka ilaa xad gaar ah. Maadaama aan nahay soo saaraha warshadda shiida birta, annagabir bir ah oo bir ah oo bir ah oo bir ah waxaa si weyn loogu isticmaalay mashruuca isticmaalka dhamaystiran ee qalabka dhismaha ee dabada birta ee dabada birta. HCMilling (Guilin Hongcheng) waxay soo bandhigi doontaa tiknoolajiyada diyaarinta qalabka dhismaha ee dabada birta.

1. Qalabka sibidhka ee Calcined

Dabin bir ah ayaa hodan ku ah curiyaha birta, kaas oo beddeli kara budada birta sida walxo cayriin ah oo loogu talagalay soo saarista dabin bir ah. Gubista dabin bir ah oo leh dhagax nuurad ah, ciid quartz ah iyo dabin bir ah oo ah walxo cayriin ah ayaa si wax ku ool ah u yareyn karta heerkulka dabin bir ah iyo kharashka sibidhka, laakiin xaddiga isku darka waa xaddidan yahay, xaddiga isku darka xad-dhaafka ahna wuxuu si weyn u yareyn doonaa xoogga sibidhka. Waqtigan xaadirka ah, tirada dabin bir ah oo loo isticmaalo dabin bir ah oo loo isticmaalo dabin bir ah oo loo isticmaalo dabin bir ah waa qiyaastii 15%. Waa degdeg in la horumariyo qalab cusub iyo tiknoolajiyad cusub si loo hagaajiyo tirada dabin bir ah loona hubiyo tayada alaabta sibidhka.

2. Isku-darka shubka

Adkaanta sare ee dabada birta waxay inta badan ka timaaddaa marxaladda quartz-ka gudaha, oo cabbirka walxaha uu ku dhow yahay ciid wabiga dabiiciga ah iyo ciid la soo saaray, waxaana lagu qasi karaa shub ahaan isku-darka. Shubka oo leh xoog 28d ah oo qiyaastii ah 40MPa waxaa lagu diyaarin karaa iyadoo la isticmaalayo dabada birta oo leh cabbir walax oo ka yar 1mm si loogu beddelo ciidda wabiga dabiiciga ah isku-darka wanaagsan. Iyada oo lagu saleynayo hagaajinta kala-soocidda wadarta, isticmaalka isku-darka ah ee dabada birta iyo ciidda mashiinka lagu sameeyo isku-darka ma buuxin karo oo keliya shuruudaha shubka ee agabka, laakiin sidoo kale waxay leedahay xasillooni ka wanaagsan tan dabada birta iyo ciidda wabiga dabiiciga ah, taas oo ka wanaagsan xakamaynta tayada shubka. Marka laga hadlayo habka faa'iidada hadda jirta, si loo hagaajiyo heerka soo kabashada birta, walxaha dabada birta ayaa sii yaraanaya oo sii yaraanaya, taas oo ay adag tahay in la buuxiyo heerka wadarta guud oo lagu dabaqo shubka caadiga ah.

3. Isku darka macdanta la shubay

Isku-darka macdanta waxaa inta badan ka kooban yihiin walxo aan qaab-dhismeed lahayn oo siliceous ah, calcareous iyo aluminium ah, kuwaas oo door muhiim ah ka ciyaara hagaajinta isku-dhafka, ka-hortagga iyo cimri dhererka shubka. Waxay yareyn karaan isticmaalka sibidhka waxayna yareyn karaan kulaylka fuuq-baxa isla waqtigaas. Sidaa darteed, waa muhiim in la helo isku-darka macdanta cusub si loo helo horumarka waara ee warshadaha sibidhka. Marxaladda macdanta ugu weyn ee daadinta birta badanaa waa quartz, kaas oo leh dhaqdhaqaaq yar oo pozzolanic ah xaalad dabiici ah. Sida loo hagaajiyo "dhaqdhaqaaqa pozzolanic" ee daadinta birta ayaa noqotay mowduuca ugu weyn ee cilmi-baarayaasha hadda jira. Iyada oo ah mid ka mid ah hababka ugu badan ee loo isticmaalo kicinta daadinta birta, shiididda farsamada waxay yareyn kartaa tamarta kicinta daadinta birta waxayna soo saari kartaa cillado badan oo shabag ah iyo isbeddel balaastig ah. Cilmi-baaristu waxay muujinaysaa in shiididda farsamada ay kicin karto dhaqdhaqaaqa pozzolanic ee marxaladaha macdanta caadiga ah ee daadinta birta. Marka cabbirka walxaha ee macdanta dhulka lagu shiiday ee farsamada hoos u dhacdo, quartz waxay la falgeli kartaa Ca (OH) 2 ee daadinta sibidhka si loo soo saaro jel calcium silicate ah oo aan qaab-dhismeed lahayn iyo kiristaal ettringite iyo alaabada kale ee fuuq-celinta. Cilmi-baaristu waxay muujinaysaa in marka shiididda farsamada ay ka badan tahay 40 daqiiqo, xagasha fiiqan ee daabka birta si cad ayaa loo dhimayaa, qaybo yaryar ayaa la soo bandhigayaa, isku-dhafkana si tartiib tartiib ah ayaa loo hagaajiyaa. Nidaamka birta anhydrite ee daabka birta ah, daabka birta siliceous ee shiididda farsamada ah waxaa lagu qasi karaa 30% si loo diyaariyo sibidh 32.5 ah. Marka la eego xaaladda saamiga biyaha oo hooseeya, budada daabka birta ee fiican waxay si weyn u horumarin kartaa fuuq-baxa hore ee koollada sibidhka ee isku-dhafan, waxay ka dhigi kartaa qaab-dhismeedka daloolka ee hoobiyaha mid aad u yar, waxayna hagaajin kartaa xoogga hore. Kordhinta aagga dusha sare ee gaarka ah ee daabka birta saameyn cad kuma lahan hagaajinta tusmada dhaqdhaqaaqa; Isbeddelka heerkulka bogsashada wuxuu si weyn u kordhin karaa tusmada dhaqdhaqaaqa marxaladda hore (7d), laakiin saameyn yar ayuu ku leeyahay tusmada dhaqdhaqaaqa marxaladda dambe (28d). Nidaamka isku-dhafka birta ee daabka birta, tusmada dhaqdhaqaaqa waxaa lagu hagaajin karaa iyadoo la hagaajinayo habka shiididda, sidaas darteedna la hagaajinayo cimriga shubka. Isticmaalka macquulka ah ee wakiilka yaraynta biyaha wuxuu kordhin karaa waxa ku jira daabka birta ee shubka caadiga ah laga bilaabo 30% ilaa 40%. Shiididda birta dailings waxay hagaajin kartaa hufnaanta shiididda iyada oo loo marayo saameynteeda, sidaas darteed waxay kicin kartaa dhaqdhaqaaqa pozzolanic ee dailings birta. Iyada oo la hagaajinayo saamiga dailings birta, slag, clinker iyo walxaha isku dhafan ee gypsum simenti, waxaa la diyaarin karaa shubka waxqabadka aadka u sarreeya oo leh waxqabad heer qaran ah.
