Inani lokuxubana lamanzi anciphisa i-ejenti lidlula inani elijwayelekile lokuxuba amahlandla ambalwa, futhi ithonya lawo ekusebenzeni kokhonkolo kufanele linqunywe ngokuya ngesimo esithile.
Esimweni sokuqala, ukhonkolo onamandla we-Ultra-wamandla aphezulu, ngoba isilinganiso se-manzi-sing ≤0.3 noma siphansi njengo-0,2, kuvame ukubonisa ukuthi isimo sikakhonkolo asinandaba nenani leAmanzi anciphisa umenzeli. Ukuze uzuze isimo esihle se-fluity, amanzi ancishisiwe. Umthamo we-ejenti uvame ukuba izikhathi ezi-5-8 umthamo ojwayelekile, okungukuthi, umthamo weI-Polycarboxylic acididinga ukufinyelela ama-5% -8%. Ukuze ukhonkolo ngezansi kwe-C50, okuqukethwe okuphezulu okunjalo kuyamangalisa. Kodwa-ke, imiphumela yokuhlola ikhombisa ukuthi amandla kakhonkolo aseminyakeni ngayinye akhula kahle ngaphansi kwaleli nani, futhi amandla angama-28D kakhonkolo alungiswa ngala mandla amakhulu kune-100MPA.
Isizathu ukuthi: Ukuhlakazwa kweAmanzi anciphisa umenzeliKusimende kungukuphela kwe-adsorption.Amanzi anciphisa umenzeliAma-molecule akwa-adsorbed ebusweni bezinhlayiyana zikakonisi. Ngokusebenzisa izithiyo ezi-steric kanye nokuxoshwa kwe-elektronikati, ukwakheka kwe-floccution ze-CEMAN CONTENESS kuyakhishwa futhi kumanzi kwamahhala kukhishwa. , Ngaleyo ndlela yandisa ukufutheka kokhonkolo, futhi ngenxa yesakhiwo sayo esikhethekile esikhethwe ngokuqinile,I-Polycarboxylic acid-akhiweAmanzi anciphisa umenzelikungavimba izinhlayiya zosekhulile kusuka ekuhlanganiseni kabusha kungakapheli isikhathi esithile, ngakho-ke inokusebenza okuhle kokugcinwa kabusha. Lapho isikhathi esithile sesidlulile, umkhiqizo we-hydration osonga ngokupheleleAmanzi anciphisa umenzeliama-molecule adderbed ebusweni bezinhlayiya zosekhukhwini. Ngemuva kweAmanzi anciphisa umenzeliAma-molecule avikelekile, ukuhlakazwa kuyanyamalala ngokuphelele, bese kungabe kusaba nomthelela noma umthonya kukhonkolo. Usimende uvame ukunamanzi amandla kakhonkolo akhula ngokujwayelekile.
Vele, ngenxa yokuqukethwe okuphezulu kweAmanzi anciphisa umenzeli, ukugxila kweAmanzi anciphisa umenzeliAma-molecule kukhonkolo makhulu. Ngemuva kokuthi amanye ama-molecule embozwe yimikhiqizo ye-Cement Hydration, ama-molecule amasha akhishwe ngaphezulu kwemikhiqizo ye-Cement Hydration, ukuvimbela izinhlayiya zosekhukhwini kusuka ekushesheni ngokushesha. Kuhlelwa inethiwekhi, edlulisa isikhathi sokusetha ngezinga elithile, kepha isilungiselelo somathelanisi ojwayelekile ngeke sidlule i-24h.
Endabeni yesibili,Amanzi anciphisa umenzelingokwayo inezakhiwo ezithile zokungena komoya kanye nokubuyisa kabusha, futhi izikhathi eziningana zokuhlanganiswa ngokweqile zingaba nomphumela omkhulu omkhulu ekusebenzeni kokhonkolo. Ngokuvamile, inani lesakhi sokubuyisa linqunywa ngokuya ngendawo yokushisa, izidingo zobunjiniyela kanye nomthamo ojwayelekile weAmanzi anciphisa umenzeli. I-adsorption ithinta i-hydration ejwayelekile yezinto eziqinisekisiwe. Esimweni esikhanyayo, isikhathi sokusetha siye eside isikhathi eside, futhi esimweni esibi kakhulu, ukhonkolo ngeke ubeke izinsuku eziningana noma unomphela. Ngokuvamile, ngokhonkolo obeke izinsuku ezi-2 noma ngaphezulu, ngenxa yokubambezeleka ngokweqile kwenqubo ye-hydration, uhlobo kanye nenani lemikhiqizo ye-hydration kuzoshintsha, okuholela ekunciphiseni okungapheli kwamandla ukhonkolo. Vele, ngoba i-Subway Occluding Piles (imvamisa i-72-90h Ukulungiselela kokuqala) kanye nokwakhiwa kokhonkolo we-Mass okufana nezisekelo zenqwaba, amakhebhu, amadamu, njll. Isikhathi eside siyadingeka. Ngokuvamile, izinga lamandla likhuphuke ngokufanele ngesikhathi sokwakhiwa kwesilinganiso sokuxubana. Qinisekisa ukuthi amandla angama-28D ahlangabezana nezidingo zokuklama.
Ukungena komoyaAmanzi anciphisa umenzelikuxutshwe kaningana kaninginingi. Lapho okuqukethwe komoya kokhonkolo kufanelekile ngesilinganiso esijwayelekile sokuxuba, okuqukethwe komoya kuzokwandiswa kakhulu ngemuva kokuxutshwa kaningana kaningi. I-slurry ekhonkolo icebe ngokungajwayelekile, futhi ukhonkolo ulula futhi uyantanta lapho igcotshwa, okuyinto ebaluleke kakhulu lapho ukhonkolo ukhululekile futhi i-porous njengesinkwa, amandla kakhonkolo ancishisiwe kakhulu.
Esimweni sesithathu, noma ngabeAmanzi anciphisa umenzelingokwayo ayinawo uhlobo lokungena komoya nolokubuyisa, ngemuva kokuphinda kabili, uma ukusetshenziswa kwamanzi kungaguqulwanga ngesikhathi, ukusebenziseka kokhonkolo okusha kungawohloka kakhulu, okuholela ecashile kakhulu. Amanzi, ukuhlukaniswa, ukubamba okuphansi, okuqinisayo, njll. , okwenza ukuba amandla okubamba insimbi ehle kakhulu. Inani elikhulu lokopha elibangelwa ukuhlanganiswa ngokweqile lizovela ebusweni balokhonkolo kanye nezingxenye ezithintana nefomu, okuholela ekunciphiseni amafomu lalezi zingxenye, kanye nenani elikhulu lezinkinga ezifana nemifantu, Izinyosi zezinyosi, kanye nezindawo ezibuyiselwe ezibuyiselwe ukuvela lapho isikhunta sisuswa, okwenza amandla akhonkolo amelana nokuguguleka kwangaphandle anciphise kakhulu, thinta kakhulu ukuqina kokhonkolo.
