1. Xaaladda hadda jirta ee ka faa'iidaysiga kheyraadka birta:

Budada slag birta ayaa muddo dheer lagu daray heerka qaranka sida isku dhafka sibidhka.Tiro badan oo tijaabo ah oo isbarbardhigga ah ayaa caddeeyey in: Marka aagga gaarka ah ee budada birta ah ee birta ah ay ka badan tahay 420m2 / kg, hawsheeda waxay la mid tahay tan foornada foornada.Isku darka isku dhafan ee budada birta ah ee birta ah iyo budada slag ma aha oo kaliya inay sii wanaajiso saamiga budada birta ee budada isku dhafan, laakiin sidoo kale waxay kordhisaa qadarka beddelka budada isku dhafan ee sibidhka iyadoo lagu saleynayo hubinta waxqabadka la taaban karo, si loo sii wado. yaree kharashka diyaarinta ee shubka.Waxay si cad u yarayn kartaa qallafsanaanta yaraanta ee binder waxayna hagaajinaysaa caabbinta dildilaaca ee binderka.Tani waxay muujinaysaa in alaabta budada slag birta ay leeyihiin rajo wanaagsan oo suuqa ah.Waqtigan xaadirka ah, xasiloonida mugga ee birta birta ah ayaa la dhimay sababtoo ah jiritaanka CaO iyo MgO bilaash ah.Maaddada sare ee oksaydhka birta waxay kordhisaa dhibka shiidada, isticmaalka sare ee isticmaalka budada ton slag, iyo dhibka habaynta budada slag birta.Sidaa darteed, mugga iibka ee suuqa budada birta birta ah waa mid yar, taas oo sidoo kale ka dhigaysa budada birta birta ah inay noqoto suuq cusub oo la horumariyo.

2. Isku darka la taaban karo waxay siinaya meel bannaan oo loogu talagalay isticmaalka shiididda birta ultrafine:

Isku-dhafka la taaban karo ee la taaban karo waa isbeddel weyn oo ku yimaada habka wax soo saarka ee mashaariicda dhismaha, iyo saamiga codsiyada la taaban karo ee diyaarsan ayaa calaamad u ah heerka wax soo saarka warshadaha ee dalka.Dhaqanku wuxuu muujinayaa in isticmaalka shubka diyaarka ah ee la isku daray ay kordhin karto wax soo saarka shaqada in ka badan labanlaab, badbaadinta sibidhka 10% ~ 15%, dhimista kharashka mashruuca ee ku saabsan 5%, waxayna hubin kartaa tayada mashruuca, badbaadinta dhulka dhismaha, yaraynta wasakhowga boodhka, si ay u gaaro dhismo cagaaran.Horumarinta shubanka ganacsigu waxay kor u qaadaysaa horumarinta wax soo saarka budada slag waxayna kordhisaa suuqa baahida budada slag.Warshada shubka isku dhafka ah ee Shiinaha oo diyaarsan ayaa la aasaasay sannadihii 1980-meeyadii, iyadoo markii hore laga dhisay Shanghai, Jiangsu iyo meelo kale, iyadoo ay ugu wacan tahay ballaarinta joogtada ah ee baaxadda dhismaha, gaar ahaan horumarka degdegga ah ee dhismaha magaalooyinka xeebaha koonfur-bari, oo ay weheliso a siyaasadaha taageerada iyo talaabooyinka isdaba jooga ah ee ay qaadeen maamulka dhismuhu, si shubka diyaarka ah ee magaalada uu kordho 15% sanadkii.Sababtoo ah qiimaha dharbaaxada birta iyo birta ayaa ka hooseeya kan sibidhka, shubka lagu qaso dhoobada iyo birta birta ayaa ah mid dhaqaale oo ku haboon isticmaalka shubka ganacsiga ee isku dhafan.Shubka la sameeyay iyadoo la isku darayo dharbaaxada iyo birta birta leh sibidhka, dhagaxa iyo ciid jaalaha ah waxay leedahay faa'iidooyinka xoogga dambe ee sare, kulaylka fuuq-baxa hooseeya, caabbinta xirashada wanaagsan iyo xoogga sare ee isku-xidhka leh biraha birta ah.Waxay si gaar ah ugu habboon tahay dhismayaasha dhaadheer, DAMS, garoomada diyaaradaha, aasaaska qoto dheer ee waaweyn iyo mashaariicda biyaha hoostooda.Waqtigan xaadirka ah, shubka xoogga aadka u sarreeya ayaa inta badan lagu diyaariyaa in lagu qaso dambaska silica iyo wakiilka biyaha yareeya waxtarka sare leh, laakiin la'aanta ash silica ash alaabta ceeriin iyo waxtarka sare ee waxtarka biyaha yareeya waa qaali, taasoo keentay qiimaha sare ee shubka.Shuruudaha sare iyo kuwa sare ee sifooyinka la taaban karo ee mashaariicda waaweyn ee gaarka ah, baahida sii kordheysa ee la taaban karo ee ganacsiga ayaa furtay suuq ballaadhan oo loogu talagalay isticmaalka ballaaran ee qashinka iyo budada birta.Fahamka dadka ee sifooyinka boodhka iyo budada birta, qalab cusub oo dhisme ah, ayaa sidoo kale sii qoto dheer.Iyada oo kor loo qaadayo laguna isticmaalo shubka ganacsiga ee dalka lana hirgelinayo halbeegyada qaranka ee la xidhiidha wax soo saarka birta iyo birta, isla markaana la hirgeliyo siyaasado ay ka mid yihiin in si adag loo mamnuuco isku-dhafka shubka ee goobaha dhismaha ee magaalooyinka, suuqa iibka iyo birta. budada slag waxay noqon doontaa mid aad iyo aad u weyn, isticmaalkeeduna wuxuu soo jiidan doonaa dareen badan oo dheeraad ah.

3. Habka diyaarinta iyo qalabka birta birta shiidida budada-yar-yar ayaa la faafiyay oo lagu dabaqay

Waqtigan xaadirka ah, tiknoolijiyada toosan ee tooska ah waxaa loo isticmaalaa in lagu shiido birta birta ah ee budada yar-yar oo soo saarta alaabada beddeleysa tamarta tamarta sare leh ee cement, taas oo iska leh tignoolajiyada wax soo saarka sare ee warshadaha.Waagii hore, sida caadiga ah slag, birta birta iyo clinker sibidhka, gypsum, iwm. wada jir ah, marka loo eego qayb gaar ah oo shiidi galay wax soo saarka shiidi ee sibidhka.Sababo la xiriira miraha liidata ee dharbaaxada iyo birta, shiididu ma noqon karto mid aad u fiican marka lagu daro clinker sibidhka, waxqabadkeeduna ma noqon karo mid si buuxda u horumarsan, iyo qadarka iyo codsiga dharbaaxada birta iyo birta ayaa xaddidan ilaa xad.Diyaarinta budada ultrafine ee ka samaysan birta birta oo keliya, Jiangsu birta iyo shirkadaha birta ayaa safka hore kaga jira.Dhowr shirkadood oo bir ah oo ay matalaan Changzhou Zhongtian Iron iyo Birta ayaa dhisay khadadka wax soo saarka birta khaaska ah ee shiididda toosan.Sida soo saaraha birta yar-yar ee budada ah ee warshadaynta toosan, Mashiinada HCM waxay ku siisaa taageero farsamo dariiqa habka wax lagu shiidi karo birta ultrafine iyo wax soo saarka qalabka warshada toosan ee muhiimka ah.Sifooyinkeeda farsamo ayaa inta badan ah dhinacyadan soo socda: xulashada warshad toosan oo shiidi doonta budada slag birta, oo leh tignoolajiyad horumarsan, wax soo saar la isku halayn karo, sifooyinka wax soo saarka shaqada ee sare, oo leh dhagax toosan si loo soo saaro tan oo ah dusha sare ee gaarka ah ee 400m2 / kg ~ 500m2 / kg boodhka, budada slag birta, marka loo eego wax soo saarka kubbadda dhaqameed ee miisaanka isku midka ah ee korantada badbaadinta budada 30% ~ 50%;Budada qafiifka ah ee birta iyo birta ayaa si toos ah loogu qasi karaa shubka, taas oo badbaadisa qadarka sibidhka sidaas awgeedna waxay badbaadisaa isticmaalka tamarta wax soo saarka sibidhka.Slag, habka wax shiididda birta, waxay si dabacsanaan u hagaajin kartaa ganaaxa alaabooyinka iyadoo loo eegayo baahida suuqa.Kordhinta kordhinta qashinka iyo birta birta ee la taaban karo, kulaylka fuuq-celinta iyo nuxurka qaybaha waxyeellada leh ee la taaban karo waa la dhimi karaa, taas oo abuureysa xaalado wanaagsan oo lagu hagaajinayo waxqabadka la taaban karo ee isticmaalka tamarta hoose.Birta birta ah waxaa lagu jeexjeexay budo shiidid toosan, maaddaduna waxay ku rushaysaa jawi qoyan oo heerkul sare ah (100 ℃ ~ 300 ℃).Inta badan calcium oxide ee bilaashka ah iyo magnesium oxide ee bilaashka ah ee birta birta ah ee budada yar yar ayaa lagu fuuqeeyaa calcium hydroxide iyo magnesium hydroxide oo firfircoon.Intaa waxaa dheer, iyada oo ay ugu wacan tahay ku darida dharbaaxada iyo birta birta ah ee la taaban karo, falcelinta wadarta alkali ayaa si wax ku ool ah loo dhimi karaa, dildilaaca yaryar ee shubka ayaa laga hortagi karaa, nolosha dhismayaasha waa la kordhin karaa.Sidaa darteed, la taaban karo oo lagu qaso budada slag ayaa lagu soo dhaweeyay warshadaha dhismaha ee sifooyinka gaarka ah.Burburinta birta oo keliya waxa loo isticmaali karaa wax soo saar la taaban karo iyo isku dhafka hadba baahida suuqa, waxaana sidoo kale lagu hagaajin karaa iyadoo loo eegayo baahida lagu hagaajinayo ganaaxa iyo qadarka isku dhafka ah ee lagu hagaajinayo sibidhka iibka ah.
