Polycarboxylic acid dej reducer yog ib hom kev ua dej ua haujlwm siab thiab yog ib hom ntawm cov nplais ua kom tawg nyob rau hauv kev siv cov vaj tse pob zeb ua ke.
Lub siab qib pob zeb nrog cov ntsiab lus siab ntawm naphthalene series dej tsim kom muaj qhov zoo dua fluidity thiab poob qis dua.Polycarboxylic acid superplasticizer tab sis qis thiab nruab nrab qib pob zeb feem ntau muaj tsis zoo fluidity thiab loj hauv paus poob.
Tib yam muaj tseeb ntawm poly carboxylic acid admixture, cov khoom siv uas nquag siv thiab kev npaj ua C30 pob zeb, admixtures nrog poly (carboxylic acid dej txo tus neeg sawv cev, qhov txiaj ntsig tau pom tias: dej txo tus neeg sawv cev ntau npaum li cas (khoom) ntawm 0.13 0.15%, ua vaj tse tuaj yeem ua tiav cov khoom ua kom tau zoo, tab sis qhov kev poob qis yog feem ntau loj, tsis hais txog dab tsi sib xyaw nrog feem ntau siv qeeb qeeb, thiab ntau npaum li cas cov koob tshuaj, thaum 0.16% kev noj cov dej txo tus neeg sawv cev, feem ntau ntawm cov pob zeb ua haujlwm tom qab 1 teev tuaj yeem ua kom muaj kua zoo.
