Okwamanje, ukusetshenziswai-polycarboxylate superplasticizerama-ejenti okunciphisa amanzi avamile ekwakhiweni, ngoba ukusebenza komkhiqizo wabo kungathuthukisa amandla okwakha kanye nekhwalithi yobunjiniyela. Lo mkhiqizo uluhlaza, awushi, futhi awuqhumi, futhi ungathuthwa ngokuphephile ngesitimela nangemoto. Lapho umthamo we-ejenti yokunciphisa amanzi ufinyelela ku-0.9% ~ 1.1%, ukuwohloka kukakhonkolo ngesilinganiso sikasimende samanzi esingu-0.12-0.16 kanye nokuqukethwe kwesihlabathi esingu-38% kusengagcinwa ngaphezu kuka-250mm amahora angu-2, ukunwetshwa kungafinyelela ku-600mm, isikhathi sokusetha sokugcina singaphakathi kwamahora angu-24, futhi asikho isenzakalo sokuhlukanisa. Amandla okucindezela ezinsukwini ezingu-90 ngisho nangaphezulu kwe-180MPa.Ngakho-ke idlala indima ebaluleke kakhulu ekwakheni, futhi okulandelayo kuzokwethula izinzuzo zayo.
1. Okuqukethwe kwe-alkali nokuqukethwe kwe-ion ye-chloride kuphansi kakhulu, kanye nokwengezwa kwei-polycarboxylate superplasticizerugologo ongumama akubangeli ukugqwala kokulimala kwezinsimbi zensimbi futhi akunamiphumela emibi kukhonkolo. Ngesikhathi esifanayo, umkhiqizo awukhiphi usawoti noma ucwebezelise phakathi nezinkathi zokushisa eziphansi, okwenza kube lula ukuwusebenzisa.
2. Kunenzuzo ekusebenzeni kwezingxube zekhonkrithi, kunciphisa ukopha, kuthuthukisa ikhwalithi yokubukeka nokuqina kokhonkolo oqinile, futhi kufanelekile ikakhulukazi ukusetshenziswa kumaphrojekthi okhonkolo angenalutho.
3. Ukhonkolo olungiselelwei-polycarboxylate superplasticizeramanzi ejenti yokunciphisa umama utshwala ngeke kubonise ukuhlukaniswa okusobala noma ukopha ngisho nangaphansi kwezimo eziphakeme zokudilika, futhi umbala wokubukeka kokhonkolo ufana. Uma usetshenziselwa ukulungisa ukhonkolo wezinga eliphezulu, ukhonkolo unokusebenza kahle, ukuhlangana okuhle, futhi kulula ukuxutshwa.
Ngakho-ke ama-ejenti okunciphisa amanzi e-polycarboxylate adingeka kakhulu ekwakheni. Lapho zisetshenziswa, zivame ukungezwa ngokulingana, okwenza iphrojekthi iqine kakhulu kodwa futhi inciphisa izingozi ezihlukahlukene. Kuphela ngokuqonda izinto ezibonakalayo kanye nezinzuzo lapho singazisebenzisa kahle esigabeni sakamuva.I-Polycarboxylate superplasticizeri-ejenti yokunciphisa amanzi iyi-ejenti yokunciphisa amanzi esebenza kahle kakhulu kanye ne-disperant ye-cement esetshenziswa ekufakweni kukasimende. Kusetshenziswa kumaphrojekthi afana nemigwaqo emikhulu, amabhuloho, amadamu, imigudu, nezakhiwo eziphakeme.
