Inta badan qashinka adag ee warshadaha Shiinaha ayaa u badan dabada, dambaska duqsiga, gangue dhuxusha, dharbaaxa dhalada, dhuxul shidista iyo gypsum desulfurization.Diyaarinta qalabka dhismaha ee qashinka adag ayaa soo jiitay dareen badan.Cilmi-baadhayaashu waxay hagaajiyeen heerka isticmaalka guud ee qashinka adag ee warshadaha qalabka dhismaha iyada oo loo marayo hagaajinta iyo cilmi-baarista iyo horumarinta qalabka iyo farsamada.Isla markaana wadamo kala duwani ay soo saareen shuruuc iyo qawaaniin taageeraya si ay u kiciyaan xamaasadda ganacsiyada ee isticmaalka qashinka adkaha ah, taas oo kor u qaadaysa saamaynta qashinka adag ee warshaduhu ku yeelanayaan deegaanka ilaa xad.Sida soo saaraha ee dabada birta wax shiidi jiray, ourdabo bir ah rullaluistemadka toosan ayaa si weyn loogu isticmaalay dabada birta ciid shiididda qalabka dhismaha mashruuca isticmaalka dhamaystiran.HCMilling (Guilin Hongcheng) waxay soo bandhigi doontaa farsamada diyaarinta qalabka dhismaha ee dabada birta ah.

1. Clinker sibidhka la kariyey

Dabada birta waxay qani ku tahay curiyaha birta, kaas oo bedeli kara budada birta sida alaabta ceeriin ee soo saarista clinker sibidhka.Ku-gubida clinker sibidhka oo leh nuurad, ciid quartz iyo dabada birta sida alaabta ceeriin waxay si wax ku ool ah u dhimi kartaa heerkulka calcination-ka iyo qiimaha sibidhka, laakiin qadarka isku-darka ayaa xaddidan, qadarka isku-dhafka xad-dhaafka ah wuxuu si weyn u dhimi doonaa xoogga sibidhka.Waqtigan xaadirka ah, qadarka dabada birta ee loo isticmaalo xisaabinta clinker sibidhka waa kaliya 15%.Waa degdeg in la horumariyo qalab cusub iyo tignoolajiyada cusub si loo hagaajiyo qadarka dabada birta iyo in la hubiyo tayada alaabta sibidhka.

2. Isku darka la taaban karo

Adkeysiga sare ee dabada birta inta badan waxay ka timaadaa wajiga quartz gudaha, kaas oo xajmigiisu uu ku dhow yahay qaar ka mid ah ciid webiga dabiiciga ah iyo ciid la soo saaray, waxaana lagu qasi karaa shubka sida wadar ahaan.Shubka leh xoogga 28d ee ku saabsan 40MPa waxaa lagu diyaarin karaa iyadoo la adeegsanayo dabo bir ah oo cabbirkeedu ka yar yahay 1mm si loogu beddelo ciidda webiga dabiiciga ah sida wadar fiican.Iyada oo ku saleysan hagaajinta isku-darka isku-darka, isticmaalka isku-dhafka ah ee birta birta ah iyo ciidda mashiinka lagu sameeyo sida wadar ahaan ma buuxin karaan oo kaliya shuruudaha shubka ee alaabta, laakiin sidoo kale waxay leedahay xasillooni ka wanaagsan tan birta birta iyo ciidda dabiiciga ah ee webiga, taas oo ka badan. waxtar u leh xakamaynta tayada la taaban karo.Marka la eego habka ka faa'iidaysiga hadda jira, si loo hagaajiyo heerka soo kabashada birta, qaybaha dabada birta ayaa sii fiicnaanaya oo sii fiicnaanaya, taas oo ay adag tahay in la buuxiyo heerka wadarta guud ee aan fiicnayn oo lagu dabaqo shubka caadiga ah.

3. Macdanta la taaban karo

Isku-dhafka macdanta ayaa inta badan ka kooban siliceous amorphous ah, calcareous iyo aluminium, kuwaas oo door muhiim ah ka ciyaara hagaajinta cufnaanta, impermeability iyo adkaysiga shubka.Waxay yareyn karaan isticmaalka sibidhka waxayna yareeyaan kulaylka fuuq-baxa isku mar.Sidaa darteed, waa muhiim in la helo isku-darka macdanta cusub ee horumarinta joogtada ah ee warshadaha sibidhka.Marxaladda macdanta ugu muhiimsan ee dabada birta badanaa waa quartz, kaas oo leh waxqabad yar oo pozzolanic ah oo ku jira xaalad dabiici ah.Sida loo hagaajiyo "hawlaha pozzolanic" ee dabada birta ayaa noqotay mawduuca ugu muhiimsan ee cilmi-baarayaasha hadda jira.Sida mid ka mid ah hababka ugu badan ee loo isticmaalo kicinta dabada birta, shiididda makaanikada waxay yareyn kartaa tamarta firfircoonida dabada birta waxayna soo saartaa cillado badan oo shaah ah iyo qallafsanaan caag ah.Cilmi-baaristu waxay muujinaysaa in shiididda makaanikada ay kicin karto dhaqdhaqaaqa pozzolanic ee wejiyada macdanta caadiga ah ee dabada birta.Maaddaama cabbirka walxaha macdanta dhulka si farsamaysan ay hoos u dhacaan, quartz waxay la falgali kartaa Ca (OH) 2 ee dareeraha sibidhka si ay u abuurto dareeraha dareeraha ah ee calcium silicate gel iyo crystal ettringite iyo alaabada kale ee fuuq-celinta.Cilmi-baaristu waxay muujinaysaa in marka mishiinka wax lagu shiido uu ka badan yahay 40min, xagasha fiiqan ee dabada birta ah ayaa si cad loo dhimay, qaybo yaryar oo badan ayaa la soo bandhigay, iyo isku-duubnida si tartiib tartiib ah ayaa loo hagaajiyaa.Nidaamka dabada birta anhydrite ee nidaamka kalsiyum oksaydh, dabada siliceous birta shiidi karo mashiinka lagu qasi karaa 30% si ay u diyaariyaan 32.5 sibidh.Marka la eego xaaladda saamiga biyaha ee hooseeya, budada dabada birta ah ee wanaagsan waxay si weyn kor ugu qaadi kartaa fuuq-baxa hore ee koollada sibidhka isku dhafan, waxay ka dhigi kartaa qaab-dhismeedka dalool ee hoobiye mid cufan, iyo hagaajinta xoogga hore.Kordhinta aagga gaarka ah ee dabada birta ah wax saameyn ah kuma laha hagaajinta tusmooyinka dhaqdhaqaaqa;Isbeddelka heerkulka daawaynta ayaa si weyn u kordhin kara tusmada dhaqdhaqaaqa ee marxaladda hore (7d), laakiin wax yar ayay ku leedahay tusmada waxqabadka ee marxaladda dambe (28d).Nidaamka isku-dhafka ah ee dabada birta ah, tusmada dhaqdhaqaaqa waxaa lagu wanaajin karaa iyada oo la wanaajinayo habka wax lagu shiidi karo, sidaas darteed wanaajinta cimriga la taaban karo.Isticmaalka macquulka ah ee wakiilka biyaha yareeya waxay kordhin kartaa waxa ku jira dabada birta ee shubka caadiga ah min 30% ilaa 40%.Dabada birtu wax shiidi kartaa waxay wanaajin kartaa hufnaanta shiida iyada oo loo marayo saameynteeda, sidaas darteed kicinta waxqabadka pozzolanic ee dabada birta.Iyada oo la wanaajinayo saamiga dabada birta, slag, clinker iyo gypsum ka kooban walxaha sibidhka, waxqabadka aadka u sarreeya ee la taaban karo oo buuxinaya heerka qaranka ayaa la diyaarin karaa.
