1.Txawm qhov polycarboxylate superplasticizer ntawm cov pob zeb dej txo kom tsawg dua, yog li cov pob zeb pob zeb qis nkag siab ntxiv rau cov dej ntxiv, yog li ua ntej yuav tsum siv yuav tsum tau sim kev sim txaus, txhawm rau nrhiav kev txawv cov khoom ntawm cov khoom nyoos thiab qib sib txawv ntawm pob zeb ua kom sib tov zoo tshaj plaws thiab tso dej kom zoo tshaj plaws.
2. Thaum polycarboxylate superplasticizer siv hloov nrog lwm cov admixtures, yuav tsum tau them nyiaj rau kev ntxuav tu cov khoom tsim nyog kom tsis txhob muaj cov khoom sib xyaw ua ke nrog cov dej txo tus neeg sawv cev nrog lwm admixtures, txo kev ua haujlwm ntawm dej txo tus neeg sawv cev.
3, dej reducer rau cov ntsiab lus av nkos ntau dua, cov av nkos yog qhov loj heev los txo cov kev ua haujlwm ntawm dej reducer. Yog li no, kev sib xyaw ua ke yuav tsum tswj hwm nruj thaum nws siv.
