I-Polycarboxylic acidUphuzo oludakayo lukamama lwenziwa ngokuqondile noma ukugxiliswa kwalo kuphakeme kakhulu, uketshezi lukamama lungene ekuhlanganiseni okuvamile kwesinciphisi samanzi akuyona inkomba elula, oketshezini lukamama lube isinciphisi samanzi esivamile ngokuya ngezinto zesihlabathi ozisebenzisayo nezimo zezulu zendawo noma izidingo zokuxuba ukhonkolo. Ukuze sikwazi ukwakha ukhonkolo, ngokuvamile sengeza ezinye izinto ezivimbela ukuqhwanda, ama-ejenti afaka umoya, ama-defoaming agents, izilondolozi, izinto eziwugqinsi, ebusika zizofaka isinqanda-qhwa.
I-ejenti yokunciphisa amanzi iyinhlanganisela evamile kakhonkolo, ayithinti ukwakhiwa kukakhonkolo nezimo ezilula, inomphumela wokunciphisa amanzi nokuqinisa ukhonkolo, i-ejenti yokunciphisa amanzi esebenza kahle kakhulu kanye ne-ejenti yokunciphisa amanzi evamile bayakwazi ukuthuthukisa ngokuphumelelayo izinto zokuxuba ukhonkolo. Ukusebenza okuguquguqukayo kwengxube kakhonkolo.Ziyinhlanganisela ebaluleke kakhulu kwezobunjiniyela bokwakha.Kodwa-ke, ngokuthuthuka kobuchwepheshe, umphumela we-ejenti yokunciphisa amanzi uya ubonakala ngokusobala, phakathi kwawo umshini wokunciphisa amanzi osebenza kahle osobala kakhulu ekuncishisweni kwamanzi nokunye. imiphumela.Ngakho-ke nge-ejenti yokunciphisa amanzi ephumelelayo ekugcineni yini ethuthuke kakhulu?Masifunde okwengeziwe.
I-ejenti yokunciphisa amanzi esebenza kahle kakhulu ibhekiselwa kupi-olycarboxylatesi-uperplasticizeri-ejenti yokunciphisa amanzi, futhii-polycarboxylic acidi-ejenti yokunciphisa amanzi ihlukaniswe nge-polycarboxylic acid evamile yokunciphisa amanzi ngepi-olycarboxylatesi-uperplasticizeri-ejenti yokunciphisa amanzi esebenza kahle kakhulu;
1.I-ejenti evamile yokunciphisa amanzi izinga lokunciphisa amanzi ngokuvamile li-5% ~ 10%;Ukusebenza kahle kwe-ejenti yokunciphisa amanzi kungafinyelela ku-12% ~ 25% noma ngaphezulu.
I-2.I-ejenti yokunciphisa amanzi esebenza kahle kakhulu ingaba kwisilinganiso sikasimende wamanzi ngaphansi kwesimo esifanayo, ithuthukise kakhulu umsebenzi kakhonkolo njengokuxuba i-ejenti yokunciphisa amanzi esebenza kahle kakhulu ingalungiselelwa ukudilika u-25cm wokhonkolo omkhulu we-fluidity, ngasikhathi sinye. ngeke ifake umoya oweqile, ngeke iholele ekumisweni okunensayo kukakhonkolo; Ngaphansi kwesimo somthamo ongaguquki usimende, ukuwohloka kukakhonkolo okuxutshwe ne-ejenti evamile yokunciphisa amanzi kuvame ukuba ngu-10cm.
3.Ekuwohlokeni kwezimo ezifanayo eziyisisekelo, i-ejenti yokunciphisa amanzi esebenza kahle kakhulu inganciphisa kakhulu ukusetshenziswa kwamanzi okuxuba ukhonkolo, yehlise kakhulu isilinganiso sikasimende wamanzi, ukuze ithuthukise kakhulu amandla kakhonkolo, i-ejenti yokunciphisa amanzi esebenza kahle kakhulu. isetshenziselwa kakhulu ukumiswa kwebanga lamandla aphezulu, izidingo eziphakeme zokunciphisa amanzi zikakhonkolo ohambahambayo; Izinga lokunciphisa amanzi le-ejenti evamile yokunciphisa amanzi liphansi kakhulu elisetshenziselwa ukulungiswa kwebanga lamandla aliphezulu, izidingo zokunciphisa amanzi aphansi zikakhonkolo.
4. Mayelana nezindleko zokulungisa, i-polycarboxylic acid esebenza kahle yokunciphisa amanzi inokuqukethwe okuqinile okuphezulu, ngakho intengo yayo iphezulu uma kuqhathaniswa;Futhi okuqukethwe okuqinile kwe-ejenti yokunciphisa amanzi kuphansi, intengo nayo ingaba ngaphansi.
I-ejenti yokunciphisa amanzi esebenza kahle kakhulu kune-ejenti evamile yokunciphisa amanzi inokunciphisa amanzi kangcono, ukuhlakazeka, nomphumela othuthukisiwe, futhi nomsebenzi wokunciphisa amanzi kanye nezinye i-ejenti yokunciphisa amanzi enemisebenzi eminingi esebenza kahle kakhulu, njenge-ejenti yokunciphisa amanzi esebenza kahle ekuqaleni, i-ejenti yokunciphisa amanzi engasebenzi kahle, i-air-entraining esebenza kahle i-jianshuiji geometric constituent yokwenziwa i-ejenti yokunciphisa amanzi esebenza kahle kakhulu inezinzuzo eziningi, ingahlangabezana kangcono nokusebenza kukakhonkolo okwenziwa lukhuni kwezinhlobonhlobo zezidingo.
