1. Ntau tus polycarboxylate superplasticizer muaj cov roj cov ntsiab lus siab thiab tsis zoo rau ntau yam tshuaj tua kab mob, yog li xav paub ntau ntxiv tuaj yeem muab rau lawv cov kev sib txuas.
Cov roj cov ntsiab lus yuav tsum tau txiav txim siab nyob rau hauv cov theem sib txuas ntawm cov qauv tsim qauv molecular.
2. Lub ntsej muag muaj txiaj ntsig tsis zoo, kev hloov kho ntawm cov cement uas twb muaj lawm yog qhov tsis zoo, qhov kev ua tau zoo yog qhov ntau qhov kev txiav txim siab, qhov pob zeb pob zeb poob yog qhov loj, npau suav ntawm poly carboxylic acid thoob ntiaj teb lub hnub nyoog tau xaus, cov tuam txhab tsim khoom yuav tsum tsim cov khoom sib txawv ntawm cov khoom, los sib cav sib txawv rau cov sib txawv, cov sib txawv PC ua sib piv ntxiv nrog cov nyhuv retarder zoo dua.
3 thaum cov xuab zeb thiab pob zeb ntsiab lus yog qhov siab, qhov hloov kho ntawm PC tsis zoo, qhov kev daws teeb meem ib txwm yog nce kev siv PC, av tuaj yeem nqus tau sai polycarboxylate superplasticizer.
Cov polycarboxylate superplasticizer yog sib xyaw nrog lwm cov tshuaj ntawm admixtures, thiab cov nyhuv siv tsis zoo. Cov raj xa dej thiab cov khoom siv hauv kev siv yuav tsum siv cais tawm ntawm lwm cov admixtures.
