Lub caij ntuj sov hloov pauv ntawm poly (carboxylic acid dej txo tus neeg sawv cev cov khoom lag luam, qab zib, qhov cuam tshuam ntawm retarder, kuj tseem muaj cov kab mob microbial, ntawm chav kawm, ntau cuam tshuam rau qhov kub thiab txias, poly carboxylic acid dej txo tus neeg sawv cev yog qhov xoob rau qhov kub thiab txias, thaum qhov kub nce , cov khoom lag luam ntawm macromolecular saw cov lus tsa suab nce ntxiv, ib zaug hauv cov lus tsa suab lub zog dhau ntawm cov tshuaj sib cuam tshuam kev sib cais lub zog, nws yuav tawm tsam cov saw decomposition, random tawg, tom qab decomposition ntawm pyrolysis, ua rau muaj kev cuam tshuam ntawm polymer ceev nrawm dua, thiab tom qab ntawd ua kom puas tsuaj poly carboxylic acid dej txo tus neeg sawv cev qhov zoo ntawm cov khoom lag luam, yog li poly carboxylic acid dej txo tus neeg sawv cev yuav tsum tau muab cia rau hauv qhov chaw txias, qhov chaw tso cua carboxylic acid, Polycarboxylic acid superplasticizer kom kub ua kom cov dej tshiab superplasticizer tuaj yeem siv sai.
Tus neeg saib xyuas dej-txo tus dej yog tam sim no ib qho ntawm qhov tsis txaus ntseeg hauv cov khoom siv pob zeb, yog li lub luag hauj lwm cov khoom dab tsi koom nrog lub luag haujlwm ntawm cov dej-txo tus neeg saib xyuas?
Hauv cov txheej txheem ntau lawm ntawm cov pob zeb ua, ib qho tseem ceeb ntawm qhov sib piv ntawm cov sib koom tes yog qhov dej / cement piv, uas yog, cov khoom siv dej / cementitious (cement active mineral sib xyaw) piv.Qhov dua qhov piv ntawm dej rau kua nplaum, qhov kev ua tau zoo dua ntawm cov hmoov av tshiab sib xyaw, qhov yooj yim kev tsim kho ntawm tus neeg sawv cev dej, polycarboxylic acid superplasticizer cov lus qhia tab sis ua ke yuav ua rau lub zog qis dua ntawm kev ua kom muaj zog hydrocoagulant.Yog hais txog kev cuam tshuam nrog kev tsis sib haum, uas yog, hauv kev txi ua haujlwm ua ke txhawm rau txhim kho lub zog ntawm cov pob zeb ua, tej zaum nyob rau hauv kev ua haujlwm tsis tu ncua thiab siv zog ua ke kom txo kev siv ntawm cov cement, lub sijhawm no yuav tsum koom nrog kev hloov dej.
