Njengoba imboni yokwakha ithuthuka ekusebenzeni okuphezulu, amandla aphezulu kanye nokuvikelwa kwemvelo okuluhlaza, izidingo zokusebenza kwezinto zokwakha ukhonkolo ziyathuthuka njalo. Ukhonkolo onamandla aphezulu usetshenziswa kabanzi ezakhiweni eziphakeme, amabhuloho, ingqalasizinda enkulu kanye neminye imisebenzi yobunjiniyela ngenxa yezakhiwo zayo ezinhle kakhulu zemishini kanye nokuqina kwayo. Njengenhlanganisela yekhonkolo esebenza kahle yesizukulwane sesithathu,isinciphisi samanzi se-polycarboxylateisibe yinto ebalulekile ekulungiseleleni ukhonkolo onamandla aphezulu ngenxa yokuhlakazeka kwawo okuphezulu kanye nokumelana nokuwa.
1. Izici zokusebenza kwe-polycarboxylate water reducer
I-Polycarboxylate water reducer uhlobo olusha lwe-high-performance water reducer eyenziwe ngokungenisa amaqembu amaningi asebenzayo ane-polyether ne-acrylic acid njenge-main chain. Isakhiwo sayo sama-molecule sakhiwe amaqembu okumunca uchungechunge oluyinhloko kanye namaqembu okuvimba uchungechunge oluseceleni, anezinga eliphezulu lokuklanywa nokusebenza. Uma kuqhathaniswa nama-naphthalene endabuko noma ama-aliphatic water reducer, ama-polycarboxylate water reducer anezinzuzo ezilandelayo ezibalulekile:
Izinga eliphezulu lokunciphisa amanzi: I-Polycarboxylate water reducer ingafinyelela izinga lokunciphisa amanzi elingaphezu kuka-20% ngesilinganiso esiphansi, inciphise ngempumelelo isilinganiso samanzi nosimende wekhonkrithi, ngaleyo ndlela ithuthukise amandla ayo.
Ukuhlakazeka okuhle kakhulu kanye nokugcinwa kokuwa: Isakhiwo sayo sama-molecule singakha ungqimba oluzinzile lokumuncwa phezu kwezinhlayiya zesimende, sinciphise ukukhangana phakathi kwezinhlayiya, futhi silondoloze ukugeleza okuhle.
Ukulahlekelwa okuphansi kokuwa: Ngokulungisa ubude beketanga eliseceleni kanye nobuningi besakhiwo sama-molecule, ukusebenza kokugcinwa kokuwa kwekhonkrithi kungathuthukiswa kakhulu ukuze kuhlangatshezwane nezidingo zokwakha isikhathi eside.
Ukuhambisana okuhle: I-Polycarboxylate water reducer iyakwazi ukuzivumelanisa kahle nezinhlobo ezahlukene zesimende kanye nezingxube zamaminerali (njengomlotha wezimpukane, i-slag powder, i-silica fume), okuhambisana kahle nomklamo wokwenza ngcono uhlelo lwekhonkrithi oluhlanganisiwe olusebenza kahle kakhulu.
Luhlaza futhi lunobungani nemvelo: Inqubo yalo yokwenziwa inobungani nemvelo, inemikhiqizo embalwa engaphansi, futhi ihlangabezana nezidingo zentuthuko esimeme.
2. Izidingo eziyisisekelo zekhonkrithi enamandla aphezulu
Ikhonkrithi enamandla aphezulu ivame ukubhekisela kukhonkrithi enamandla okucindezela angama-cubic angu-C60 nangaphezulu. Ukuze kufezwe amandla aphezulu, isilinganiso samanzi nosimende kumele sincishiswe ngenkathi kuqinisekiswa ukusebenza okuhle kokwakhiwa (njengokukwazi ukumpompa, ukugeleza kwamanzi) kanye nokuqina. Ngenxa yalokhu, kubalulekile ukusebenzisa izinciphisi zamanzi ezisebenza kahle kakhulu ukuthuthukisa ukusebenza kahle kwekhonkrithi, futhi izinciphisi zamanzi ze-polycarboxylate ziyisinqumo esifanele sokufeza lo mgomo.
3. Izinzuzo ze-polycarboxylate water reducer kukhonkrithi enamandla aphezulu
Thuthukisa amandla okuqala nangemuva: i-polycarboxylate water reducer inciphisa kakhulu isilinganiso samanzi nosimende ngenkathi igcina ukugeleza okuhle, ukuze usimende umanziswe ngokugcwele, ithuthukise kakhulu amandla okuqala nangemuva kosimende, futhi ihlangabezane nezidingo zomklamo wezakhiwo ezinamandla aphezulu.
Thuthukisa ubuningi besakhiwo sekhonkrithi: ukunciphisa isilinganiso samanzi nosimende ngaphandle kokuthinta ukusebenza kahle, kusiza ukunciphisa ama-capillary, ukuthuthukisa ubuningi kanye nokungangeni kwamanzi kwekhonkrithi, nokuthuthukisa ukuqina kwayo.
Thuthukisa ukusebenza kokwakhiwa: Kukhonkolo enamandla amakhulu, ingxube ivame ukuba yinkimbinkimbi ngenxa yenani elikhulu lesimende. Ukuhlakazeka okuhle kakhulu kwesinciphisi samanzi se-polycarboxylate kungathuthukisa ngempumelelo ukugeleza kwekhonkolo, kunciphise ukuhlangana, futhi kuthuthukise ukusebenza kahle kokupompa.
Umphumela wokuhlanganiswa nezingxube zamaminerali ubalulekile: i-polycarboxylate water reducer inomphumela omuhle wokubambisana nezingxube ezifana nomlotha wempukane, i-slag powder, kanye ne-silica fume, okusiza ekwenzeni ngcono izakhiwo eziphelele zekhonkrithi, njengokuqina, ukuqina, ukushwabana, njll.
Nciphisa izindleko eziphelele: Nakuba intengo yeyunithi ye-polycarboxylate water reducer iphakeme kakhulu, ukusebenza kwayo kahle kunganciphisa ukusetshenziswa kwesimende, kunciphise ukusetshenziswa kwamandla, kuthuthukise ikhwalithi yephrojekthi, futhi kuzuze izinzuzo zomnotho eziphelele.
4. Ukuhlaziywa kwecala lesicelo
Kuphrojekthi yokwakha ephakeme kakhulu, izinga lamandla ekhonkrithi liyadingeka ukuthi libe yi-C80, futhi lisebenza kahle futhi lihlala isikhathi eside. Ithimba lephrojekthi lisebenzise i-polycarboxylate high-performance water reducer, ehlanganiswe ne-silica fume kanye ne-slag powder composite admixtures, futhi lakha ngempumelelo ikhonkrithi enamandla aphezulu eyahlangabezana nezidingo zomklamo ngokwenza ngcono isilinganiso samanzi nesamente kanye nosayizi wezinhlayiya. Imiphumela yokuhlolwa ikhombisa ukuthi amandla okucindezela ekhonkrithi ezinsuku ezingu-28 adlula i-85 MPa, kanti isikhathi sokugcina ukuwohloka singaphezu kwamahora ama-2, okuhlangabezana nezidingo zokwakha nokupompa endaweni, futhi kukhombisa nezakhiwo ezinhle zokulwa nokubanda, ukuvimbela ukuvuza kanye nokulwa ne-carbonation.
5. Izinkinga ezikhona kanye nezinkomba zentuthuko
Nakuba i-polycarboxylate water reducer isetshenziswa kabanzi kukhonkolo enamandla amakhulu, kusenezinselele ezilandelayo kumaphrojekthi angempela:
Izinkinga zokuhambisana nosimende othile: Ezinye izinhlobo zesimende zingabangela ukuthi isinciphisi samanzi sehluleke noma ukusebenza kokugcinwa kokwehla kwehle, futhi kudingeka ucwaningo lokuzivumelanisa nezimo.
Ukuzwela okuphezulu endaweni yokwakha: I-Polycarboxylate water reducer iyazwela ezimweni zemvelo ezifana nokushisa nomswakama, futhi izimo zokusebenzisa zidinga ukulawulwa ngokufanele.
Inqubo yokuhlanganisa iyinkimbinkimbi futhi izindleko ziphezulu: Njengamanje, amaphrojekthi obunjiniyela asebenza kahle kakhulu aseyizindawo eziyinhloko zokusetshenziswa, futhi kuyaphuthuma ukunciphisa izindleko ngokusebenzisa ukulungiswa kwenqubo ukuze kukhuthazwe ukuthandwa kwayo.
Ukuthuthukiswa kwe-polycarboxylate water reducer kuzogxila kulezi zici ezilandelayo: Okokuqala, ukwenziwa ngcono okwengeziwe kwesakhiwo sama-molecule ukuze kufezwe ukuthuthukiswa okuhambisanayo kokunciphisa amanzi kanye nokusebenza kokugcinwa kokuwa; okwesibili, ukuthuthukiswa kwe-smart water reducer, njengohlobo oluzwela ekushiseni, uhlobo lokukhululwa kancane, njll.; okwesithathu, ucwaningo ngendlela yokwenziwa eluhlaza kanye nemvelo yokukhuthaza intuthuko esimeme; okwesine, ukwakheka okuhlakaniphile kwesilinganiso sokuxuba ukhonkolo kuhlanganiswe ne-AI noma i-big data.
Isinciphisi samanzi se-Polycarboxylateisibe yinhlanganisela eyinhloko yokulungiselela ukhonkolo onamandla aphezulu ngokusebenza kwayo okuhle kakhulu. Ngomklamo nokusetshenziswa kwesayensi okunengqondo, ayikwazi nje ukuhlangabezana nezidingo eziningi zekhonkolo esebenza kahle kakhulu yobuchwepheshe kanye nokusebenza kahle, kodwa futhi ithuthukise ikhwalithi yobunjiniyela kanye nokusebenza kahle kokwakha. Emongweni wokuthuthukiswa okuqhubekayo kobuchwepheshe bokwakha esikhathini esizayo, i-polycarboxylate water reducer izosebenzisa amandla ayo amakhulu ensimini ebanzi.
