Iyini i-ejenti yokunciphisa amanzi?

I-ejenti yokunciphisa amanzi ibhekisela ezintweni ezinganciphisa inani lamanzi okuxuba futhi zingathuthukisa amandla kakhonkolo lapho ukusebenza kukakhonkolo kanye nenani likasimende lihlala lingashintshiwe.. Iphinde ibhekisele ezintweni ezingasindisa ingxube kasimende ngaphansi kwesimo sokusebenza okungapheli namandla.

Siyini ukuhlukaniswa kwe-ejenti yokunciphisa amanzi?

Ngokwekhono layo lokunciphisa nokuthuthukisa amanzi, ihlukaniswe yaba i-ejenti evamile yokunciphisa amanzi (eyaziwa nangokuthi i-plasticizer) kanye ne-ejenti yokunciphisa amanzi esebenza kahle kakhulu (eyaziwa nangokuthi super plasticizer), nawo ahlukaniswe abe yimikhiqizo esezingeni lokuqala nefanelekile.

Ngokusho kwengxenye yezinto zayo, ihlukaniswe yaba :(1) amanzi sulfonates; (2) i-polycyclic usawoti omnandi; (3) I-resin sulfonates encibilikayo emanzini.

Okwamanje, ama-superplasticizers amaningana asetshenziswa kakhulu emakethe: i-naphthalene series superplasticizer, i-aliphatic group superplasticizer, i-amino superplasticizer, superplasticizer, ukusebenza okuphezulu kwe-ejenti yokunciphisa amanzi, i-ejenti ye-slushing NF, ukuqina kuyashesha kanye nokunciphisa amanzi, sodium lignosulfonate, i-lignosulfonate, i-ejenti yokwandisa, njll.

Yini engasetshenziselwa i-ejenti yokunciphisa amanzi?

Uyini umphumela wezobuchwepheshe nezomnotho wokuxuba i-superplasticizer kukhonkolo?

(1) I-fluidity yekhonkrithi ingandiswa kakhulu ngokugcina isilinganiso sokuxuba sikakhonkolo singashintshiwe;

(2) ukugcina uketshezi lukakhonkolo kanye nenani likasimende lingashintshiwe kunganciphisa ukusetshenziswa kwamanzi futhi kuthuthukise amandla;

(3) Ukugcina uketshezi namandla okufanayo kunganciphisa inani likasimende;

(4) ukugcina imfuneko ye-fluidity kakhonkolo ingashintshiwe kunganciphisa ukusetshenziswa kwamanzi futhi kuthuthukise ukumelana nesithwathwa kanye nokumelana nokuqina kukakhonkolo;

(5) Ingabambezela ukukhishwa kokushisa kwe-hydration kukasimende, ukunciphisa ukucindezeleka kwezinga lokushisa kukhonkolo enkulu, futhi unciphise amathuba okuqhekeka.
