Soo saaraha KaalshiyamkaKiimikada Aojin waxay kula wadaagtaa codsiyada kaalshiyamka ee warshadaha sibidhka dhismaha. Kaalshiyamka ay iibiso Aojin Chemical wuxuu leeyahay xaddi badan oo ah 98% waxaana lagu baakadeeyaa 25kg/bac.
Shirkadda soo saarta kaalshiyamka ee Aojin Chemical waxay la wadaagtaa adeegsigeeda warshadaha sibidhka dhismaha. Aojin Chemical waxay iibisaa kaalshiyam 98% ah oo ku jira bacaha 25kg.
Kaalshiyam qaabaysan (Ca(HCOO)₂), oo ah wakiil awood hore oo dabiici ah oo aad waxtar u leh, ayaa loo isticmaalaa soo saarista alaabada sibidhka iyo sibidhka sababtoo ah sifooyinka kiimikada ee gaarka ah. Shaqooyinkeeda iyo adeegsigeeda aasaasiga ah waa sidan soo socota:
1. Xoojinta Hore iyo Dardargelinta Dejinta
Kaalshiyamku wuxuu si weyn u dardar geliyaa fuuq-celinta sibidhka, gaar ahaan fuuq-celinta tricalcium silicate (C₃S) iyo tricalcium aluminate (C₃A). Tani waxay dardar gelinaysaa sameynta iyo dejinta alaabada fuuq-celinta (sida ettringite iyo calcium hydroxide), taasoo hagaajinaysa xoogga hore ee agabka ku salaysan sibidhka (xooggu wuxuu kordhi karaa 20%-50% 1-7 maalmood gudahood). Hantidani waxay ka dhigaysaa mid si gaar ah ugu habboon dhismaha heerkulka hooseeya (sida daadinta jiilaalka) ama mashaariicda dayactirka degdegga ah, iyadoo soo gaabinaysa muddada bogsashada iyo hubinta in shubku si caadi ah u adkaado deegaannada heerkulka hooseeya, sidaas darteedna ka hortagga dhaawaca barafowga.
2. Shaqaynta iyo Waarta ee Shabakadda oo La Hagaajiyay
Koolada sibidhka, kaalshiyamku wuxuu yareeyaa dhiigbaxa iyo kala soocidda, isagoo hagaajinaya isku-dhafka iyo cufnaanta shubka. Intaa waxaa dheer, alaabta fuuq-baxa waxay buuxisaa daloolada koolada sibidhka, iyagoo yareynaya daloolada, si dadban u xoojinaya in sibidhka uusan u dul-qaadin, iska caabbinta dhaxanta, iyo iska caabbinta daxalka, taasoo kordhinaysa cimriga adeegga ee alaabta sibidhka.
3. Ku habboon codsiyada kala duwan ee alaabta sibidhka
Wax soo saarka qaybaha hore loo shubay, sida looxyada hore loo shubay iyo tuubbooyinka tuubada, kaalshiyamku wuxuu dardar geliyaa isbeddelka caaryada, wuxuu soo gaabiyaa waqtiga burburinta, wuxuuna hagaajiyaa hufnaanta wax soo saarka.
Shotcrete: Waxaa loo isticmaalaa hawlgallada buufinta godadka, macdanaha, iyo mashaariicda kale, si dhakhso ah ayuu u dejiyaa oo u adkaadaa, isagoo yareeya khasaaraha dib-u-soo-noqoshada iyo hagaajinta hufnaanta dhismaha.
Maaddooyinka Hoobiyaha iyo kuwa dhagaxa: Waxay hagaajisaa haynta biyaha iyo xoogga hore ee hoobiyaha, taasoo hubinaysa horumar degdeg ah oo ku yimaada hababka dhagaxa iyo malaasaynta.
4. Faa'iidooyinka Deegaanka iyo Iswaafajinta
Qiimaha Kaalshiyamkawaa mid aan sun ahayn oo aan dhib lahayn, waana mid la jaanqaadi karta sibidhka, wakiilada biyaha yareeya, dambaska duulista, iyo isku-darka kale. Ma keento dhibaatooyin sida falcelinta alkali-isku-darka ee sibidhka, iyadoo daboolaysa baahiyaha horumarinta agabka dhismaha ee cagaaran. Fiiro gaar ah: Qiyaasta kaalshiyamka qaabaysan waa in si adag loo xakameeyaa (badanaa 1%-3% cufka sibidhka). Ku darista xad-dhaafka ah waxay hoos u dhigi kartaa koritaanka xoogga dambe ee sibidhka xitaa waxay sababi kartaa dildilaac yar. Hagaajinta waa in lagu sameeyaa iyadoo lagu saleynayo arrimo ay ka mid yihiin deegaanka mashruuca iyo nooca sibidhka.
