I-superplasticizer esebenza kahle kakhulu emelwe i-polycarboxylate superplasticizer inezinzuzo zokuqukethwe okuphansi, izinga eliphezulu lokunciphisa amanzi, ukusebenza kahle kokugcinwa kokuwohloka kanye nokuncipha okuphansi, kanye ne-polycarboxylate superplasticizer superplasticizer inenani elithile lembangela, eyenza uketshezi, ukumelana nesithwathwa nokugcinwa kwamanzi. kakhonkolo kangcono kune-superplasticizer yendabuko. Ngenxa yenqubo ehlukahlukene yokuhlanganisa ye-polycarboxylate superplasticizer, ikhwalithi yomkhiqizo yabakhiqizi abahlukene ihluke kakhulu, kuhlanganiswe nenqubo yokukhiqiza, ngenxa yokuguquguquka kwekhwalithi yezinto zokusetshenziswa zikakhonkolo, ukushintshwa kokuqukethwe kwamanzi esihlabathini, iphutha uhlelo lokulinganisa nezinye izizathu, okuholela emsebenzini ongazinzile wengxube kakhonkolo (kulula ukuhlukanisa noma ukulahlekelwa ukuwohloka ngokushesha okukhulu) enqubweni yokwakha ye-polycarboxylate superplasticizer. Ayikwazi nokuhlangabezana nezidingo zokwakha. Indlela yokukhetha i-polycarboxylate superplasticizer okulula ukuyilawula futhi kulula ukuyikhiqiza ikhwalithi ezinzile ingenye yezinto ezibalulekile zokufinyelela izinga elizinzile likakhonkolo.
Ekukhetheni i-polycarboxylate superplasticizer ngaphezu kokuhlolwa kokusebenza okuyisisekelo, okufana nokuqukethwe okuqinile, izinga lokunciphisa amanzi, ukugcinwa kokuwa kanye nezinye izivivinyo zokusebenza, ukuzwela kwe-polycarboxylate superplasticizer kufanele kuhlolwe ukuze kuhlolwe ngokuphelele ikhwalithi ye-polycarboxylate superplasticizer.
(1) Ukuzwela kokutholwa ekushintsheni umthamo
Lungisa isilinganiso sokuxutshwa kukakhonkolo esivivinyweni sibe sesimweni sokuthi ukusebenza nokugcinwa okuxegayo kwengxube kakhonkolo kuhlangabezana nezidingo, gcina umthamo wezinye izinto zokusetshenziswa zikakhonkolo ungashintshiwe, wandise noma wehlise inani lengxube ngo-0.1% noma ngo-0.2% ngokulandelana, futhi thola ukwehla nokwandiswa kukakhonkolo ngokulandelana. Umehluko omncane phakathi kwevelu elinganisiwe kanye nesilinganiso esiyisisekelo sokuhlanganisa, uzwela kancane ekushintsheni kwenani lokuxuba. Kuboniswa ukuthi i-ejenti yokunciphisa amanzi inokuzwela okuhle kumthamo. Inhloso yalokhu kutholwa ukuvimbela isimo sengxube kakhonkolo ekushintsheni okungazelelwe ngenxa yephutha lesistimu yokulinganisa.
(2) Ukuthola ukuzwela izinguquko ekusetshenzisweni kwamanzi
Ngokufanayo, ngokusekelwe esilinganisweni sokuxuba ukuxuba kukakhonkolo lapho kuhlangabezana nezidingo, inani lezinye izinto zokusetshenziswa lihlala lingashintshiwe, futhi ukusetshenziswa kwamanzi kakhonkolo kuyanda noma kwehliswa ngo-5-8kg/cubic meter ngokulandelana, okungukuthi, ukushintshashintsha umthamo wamanzi esihlabathi ulingisa ngo-1%, futhi ukuwohloka nokwandiswa kwengxube kakhonkolo kuyalinganiswa ngokulandelana. Uma umncane umehluko phakathi kwengxube kakhonkolo kanye nesilinganiso esiyisisekelo sokuxuba, kuba ngcono ukuzwela kokusetshenziswa kwamanzi kwesinciphisi samanzi. Uma ushintsho ekusetshenzisweni kwamanzi lungazweli, kungaba lula ukulawula ukukhiqizwa.
(3) Hlola ukuguquguquka kwezinto zokusetshenziswa
Gcina isilinganiso esiyisisekelo sokuxuba singashintshiwe, buyisela izinto zokusetshenziswa kokhonkolo, ngokulandelana uvivinye izinguquko zokuwohloka nokunwetshwa kwengxube kakhonkolo ngemva koshintsho, futhi uhlole ukufaneleka kokuzivumelanisa nezinto zokusetshenziswa.
(4) Ukuguquguquka kwezinga lokushisa
Gcina i-basic mix ratio ingashintshiwe, ngokulandelanayo hlola ukuguqulwa kokuwohloka nokunwetshwa kwengxube kakhonkolo ngemva koshintsho, hlola ukujwayela kokuvumelana nezinto ezingavuthiwe.
(5) Shintsha izinga lesihlabathi
Khulisa noma wehlise izinga lesihlabathi ngo-1%, bheka isimo sengxube kakhonkolo, hlola ukushintshashintsha kwenani lesihlabathi namatshe, kanye nokuthi isimo sikakhonkolo sishintshe kakhulu yini.
