1, kev tsim cov kab mob polycarboxylic acid dej txo cov txheej txheem kev ua qias tuaj, tsis pub dawb, formaldehyde dawb, ntsuab ib puag ncig kev tiv thaiv.
2, polycarboxylate dej reducer stability, ntev cia tsis muaj stratification, deposition tsos nres, tsis kub tsis muaj siv lead ua sib cais, thiab lwm yam.
3, dej reducer chloride ion cov ntsiab lus yog qhov tsawg, tsis tshua muaj alkali cov ntsiab lus, yog qhov zoo txhawm rau txhim kho kev ua vaj tse ruaj khov.
4. Lub zog thaum ntxov thiab 28-hnub lub zog ntawm polycarboxylate superplasticizer tau zoo dua tuaj, tshwj xeeb tshaj yog haum rau cov pob zeb nrog cov ntsiab lus siab ntawm cov ntoo tshauv.
5. Thaum cov ntsiab lus yog 0.5% ~ 1.5%, cov dej txo qis yog 18-40%, uas tuaj yeem txaus siab qhov kev thov rau cov ua haujlwm siab fluidity.
6. Cov txiaj ntsig kev lag luam zoo, qis dua kev siv tshuab hluav taws xob tsis zoo dua li kev siv lwm hom kev ua kom cov dej-txo tus neeg ua haujlwm, tib lub zog tuaj yeem txuag 15-25% xis mas.
7. Qhov kev ua zoo ntawm cov dej-txo tus neeg sawv cev no muaj qhov zoo khaws cia, uas ua raws li qhov yuav tsum tau ua rau tus kav dej thiab lub qhov poob qis yog qhov txo qis.
8. Cov pob zeb ua haujlwm muaj qhov ua tau zoo tshaj plaws, tsis muaj qhov sib cais, tsis pom qhov tsis los ntshav, thiab xim tsis zoo ntawm cov pob zeb ci tshwm;
Thaum siv los npaj qib siab ua vaj tse, pob zeb qhob tau sib xyaw zoo thiab yog yooj yim do.
