Tom qab txiav txim siab kev sib koom tes kub ntawm cov khoom siv sib txawv nrog cov haujlwm sib txawv ntawm cov khoom, nws tuaj yeem pom sai sai tias cov dej-txo cov teebmeem ntawm polycarboxylate niam cawv feem ntau yog muab los ntawm macromolecular monomer, uas yog ntaus nqi rau pawg carboxyl thiab ethylene glycol hauv cov polyethylene macromolecule.Its derivatives yog hydrophilic.Qhov kev ua haujlwm ntawm macromolecular monomer, peb yuav ntxiv cov qauv kom muaj nuj nqis, kom tau txais cov qauv pulp ua haujlwm tau yooj yim pom lub luag haujlwm ntawm macromolecular monomer hauv cov lus sib xyaw.Qhov cuam tshuam ntawm cov txheej txheem sib txawv ntawm cov khoom ua haujlwm yog ua raws cov yam ntxwv ntawm cov organic sib xyaw: vim tias muaj ntau cov tshuaj tiv thaiv nyob rau hauv cov organic, cov khoom sib txawv yog tsim los ntawm cov kev sib txawv poob.Yog li ntawd, qhov kev sib txawv ntawm cov haujlwm pulp tau txais los ntawm kev hloov pauv hauv lwm yam mob kuj txawv heev. Yog li, thaum lub sijhawm lwm yam mob tau hloov pauv, peb tuaj yeem txuag nyiaj los ntawm changin g tus txheej txheem.
Cov txiaj ntsig ntawm cov saw hloov ntawm tus neeg sawv cev ntawm cov khoom lag luam hloov xa tus neeg sawv cev koom nrog feem ntau yog los ntawm kev ua haujlwm ntau tshaj cov molecular phaus thiab faib cov molecular phaus faib kom tsis txhob sib txuas sib txuas.Yog hais tias qhov kev koom tes ntau dhau, nws yuav twv yuav raug txo kom txo cov molecular. nyhav, thiab tom qab ntawd cov dej-txo cov nyhuv ntawm polycarboxylic acids yuav phem dua, thiab kev ua haujlwm tu yuav raug txo kom tsawg.Rau cov khoom zoo dua, peb yuav ua kom zoo dua cov saw xa mus rau tus neeg sawv cev kom ua tiav cov txiaj ntsig zoo tshaj plaws.
Cov nyhuv ntawm carboxylic acid monomer ntawm cov khoom ua haujlwm acrylic acid yuav ua lub luag haujlwm hauv qhov tsis txaus ntawm pawg carboxyl thiab calcium ion hauv cov saw tseem ceeb ntawm chav rov ua haujlwm, thiab cov txheej txheem muaj cov loj loj solubility.Property muab cov xwm txheej rau cov dej txuas ntxiv ntawm cov cement, yog li nws muaj qhov ua tau zoo ntawm cov dej num ntawm cov khoom siv hluav taws xob thiab lub zog thaum ntxov ntawm kev ua vaj tse.
