Isinyathelo 1: ukuhlola i-alkalinity kasimende

Hlola inani le-pH likasimende ohlongozwayo, futhi usebenzise i-pH, imitha ye-pH noma ipeni le-pH ukuhlola. Imiphumela yokuhlolwa ingasetshenziselwa ukunquma kusengaphambili: ukuthi inani le-alkali encibilikayo kusimende likhulu noma lincane; kungakhathaliseki ukuthi i-admixture kusimende i-acidic noma i-inert material efana ne-stone powder, eyenza inani le-pH liphansi.

Isinyathelo sesi-2: uphenyo

Ingxenye yokuqala yophenyo ukuthola imiphumela yokuhlaziywa kwe-clinker kasimende. Bala okuqukethwe kwamaminerali amane kusimende: i-tricalcium aluminate C3A, i-tetracalcium aluminoferrite C4AF, i-tricalcium silicate C3S kanye ne-dicalcium silicate C2S.

Ingxenye yesibili yophenyo iwukuqonda ukuthi hlobo luni lwezingxube olunezelwayo lapho iklinka igaywa kusimende nokuthi yengezwa malini, okuwusizo kakhulu ekuhlaziyeni izimbangela zokopha okukhonkolo kanye nesikhathi sokumisa esingavamile (side kakhulu, sifushane kakhulu).

Ingxenye yesithathu yophenyo ukuqonda ukuhlukahluka kanye nokucoleka kwezixube ezikhonkolo.

Isinyathelo sesi-3: Thola inani ledosi eligcwele

Thola inani eligcwele lethamo lesinciphisi samanzi esisebenza kahle kakhulu esisetshenziselwa lesi simende. Uma izinciphisi zamanzi ezimbili noma ngaphezulu ezisebenza kahle kakhulu zixutshwe, thola iphoyinti lethamo eligcwele ngokuhlolwa kokunamathisela usimende ngokuya ngenani eliphelele lengxube. Ukusondela komthamo wesinciphisi samanzi esisebenza kahle kakhulu kumthamo ogcwele usimende, kuba lula ukuthola ukuguquguquka okungcono.

Isinyathelo sesi-4: Lungisa i-plasticization degree ye-clinker ebangeni elifanele

Lungisa izinga le-alkali sulfation kusimende, okungukuthi, i-plasticization degree ye-clinker ebangeni elifanele. Ifomula yokubala yenani le-SD ledigri ye-plasticization ye-clinker ithi: SD=SO3/(1.292Na2O+0.85K2O) Amanani wokuqukethwe wengxenye ngayinye afakwe ohlwini lokuhlaziya i-clinker. Ububanzi bevelu ye-SD bungu-40% ukuya ku-200%. Uma iphansi kakhulu, kusho ukuthi kune-sulphur trioxide encane. Isamba esincane sikasawoti esinesulfure njenge-sodium sulfate kufanele yengezwe ku-admixture. Uma iphakeme kakhulu, kusho ukuthi i-molecule inkulu, okungukuthi, kune-sulphur trioxide eyengeziwe. Inani le-pH lenhlanganisela kufanele lenyuke kancane, njenge-sodium carbonate, i-caustic soda, njll.

Isinyathelo sesi-5: Ingxube yokuhlola eyinhlanganisela yenhlanganisela futhi uthole uhlobo nomthamo wamasethingi

Lapho izinga lesihlabathi limpofu, njengokuqukethwe kodaka oluphezulu, noma lapho zonke izihlabathi zokwenziwa nesihlabathi esicwebezelayo zisetshenziselwa ukuxuba ukhonkolo, ngemva kokuba ukuhlolwa kwe-net slurry kuthola imiphumela egculisayo, kuyadingeka ukuqhubeka nokwenza ukuhlolwa kodaka ukuze kuthuthukiswe ukulungisa ukuguquguquka ne-admixture.

Isinyathelo sesi-6: Ukuhlolwa kukakhonkolo Ukuze kuhlolwe ukhonkolo, inani lengxube akufanele libe ngaphansi kwamalitha ayi-10

Ngisho noma i-net slurry ilungiswe kahle, ingase ingafinyeleli okulindelwe kukhonkolo; uma i-slurry inetha ingalungiswanga kahle, ukhonkolo ungaba nezinkinga ezinkulu.Ngemva kokuba inani elincane lokuhlola liphumelele, ngezinye izikhathi inani elikhulu lidinga ukuphindaphindiwe, njengamalitha angu-25 kuya ku-45 amalitha, ngoba imiphumela ingase ihluke kancane. Kuphela uma inani elithile lokuhlola okuphathekayo liphumelela lapho ukulungiswa kokuvumelana nezimo kungaqedwa.

Isinyathelo sesi-7: Lungisa isilinganiso sengxube kakhonkolo

Ungakwazi ukwandisa noma unciphise inani lezinto ezixubene nezimbiwa ngendlela efanele, futhi uguqule ingxube eyodwa ibe yingxube ephindwe kabili, okungukuthi, sebenzisa izixube ezimbili ezihlukene ngesikhathi esisodwa. Akungabazeki ukuthi inhlanganisela ephindwe kabili ingcono kunenhlanganisela eyodwa; ukwandisa noma ukunciphisa inani likasimende kungaxazulula izinkinga zokunamathela kukakhonkolo, ukulahlekelwa ukuwohloka ngokushesha nokopha kukakhonkolo, ikakhulukazi ukuchayeka kwesihlabathi; ukwandisa kancane noma ukunciphisa inani lamanzi; ukwandisa noma ukunciphisa isilinganiso sesihlabathi, noma ngisho nokushintsha kancane uhlobo lwesihlabathi, njengenhlanganisela yesihlabathi esimahhadlahhadla nesicolekileyo, isihlabathi semvelo nesihlabathi sokwenziwa, njll.
