Isicelo Se-ejenti Yokunciphisa Amanzi Esisebenza Kakhulu

1. Ukwenza Ngokwezifiso Isakhiwo Samangqamuzana

I-ejenti yokunciphisa amanzi ye-polycarboxylate ene-side chain density engu-≥1.2 nge-nm² ngayinye. Umthelela wayo wesithiyo oqinile unganciphisa umonakalo we-adsorption layer obangelwa amazinga okushisa aphezulu. Uma ingezwe ngengxube yomlotha wempukane engu-30%, izinga lokunciphisa amanzi lingafinyelela ku-35% -40%, ngokulahleka kokuwohloka kwehora elilodwa okungaphansi kuka-10%. Le ejenti yokunciphisa amanzi ye-polycarboxylate yamaketango aphezulu yakha ungqimba oluwugqinsi lwe-adsorption ebusweni bezinhlayiya zikasimende, linikeza ukunyanyiswa okuqinile okuqinile, okuvumela izinhlayiya zikasimende ukuthi zigcine isimo esihlakazeke kahle ngisho nasezindaweni ezishisa kakhulu. Ngaphezu kwalokho, ukungezwa komlotha wempukane akugcini nje ukunciphisa ukusetshenziswa kukasimende futhi kwehlisa ukushisa kwe-hydration, kodwa futhi kudala umphumela we-synergistic ne-ejenti yokunciphisa amanzi, okuqhubeka nokuthuthukisa ukusebenza nokuqina kukakhonkolo.

2. I-Slump-Preserving Synergistic TechnologyUkwethulwa kwe-methyl allyl polyoxyethylene ether monomer kudala isakhiwo senethiwekhi esinezinhlangothi ezintathu. Endaweni yokulingisa ku-50 ° C, kuhlanganiswe nengxenye yokuhlehlisa, ukunwetshwa kwekhonkrithi kungagcinwa ngaphezu kuka-650mm imizuzu engu-120, ukuhlangabezana nezidingo zokumpompa izakhiwo eziphakeme kakhulu. Ukwethulwa kwe-methyl allyl polyoxyethylene ether monomers kushintsha ukwakheka kwamangqamuzana e-polycarboxylate superplasticizer, kwakha isakhiwo senethiwekhi esinezinhlangothi ezintathu esithuthukisa ikhono layo lokuhlanganisa nokuhlakaza izinhlayiya zikasimende. Ezindaweni zokushisa okuphezulu, lesi sakhiwo simelana ngokuphumelelayo nokuphazanyiswa kwemikhiqizo ye-cement hydration, ukugcina uketshezi kanye nokwehla kokhonkolo. Uma isetshenziswa ngokuhambisana nezingxenye ezihlehlisayo, ingabambezela ngesikhathi esisodwa ukugeleza kukasimende futhi igcine ukuwohloka, ihlangabezane nezidingo zokwakha ukhonkolo osebenza kahle kakhulu, njengokumpompa okuphakeme kakhulu.
