Dab tsi yog cov khoom tseem ceeb ntawm masterbatch ntawm polycarboxylate superplasticizer, thiab dab tsi yog qhov proportions ntawm txhua yam?
Raws li cov qauv sib txawv ntawm nws cov saw tseem ceeb, polycarboxylic acid-based high-efficiency dej txo tus neeg sawv cev cov khoom tuaj yeem muab faib ua ob pawg: ib qho yog polyether nrog acrylic acid lossis methacrylic acid ua cov saw tseem ceeb thiab grafted nrog cov saw ntev sib txawv. Lwm hom yog polyether nrog maleic anhydride ua lub ntsiab txuas ceg nrog sib txawv sab saw ntev.
Raws li qhov no, cov khoom ua tau zoo ntawm cov dej txo cov neeg sawv cev nrog cov yam ntxwv sib txawv tau muab los. Qhov no yog cov khoom tseem ceeb ntawm polycarboxylic acid, thiab qhov kev faib ua feem ntawm cov khoom xyaw feem ntau yog tsim raws li cov kev xav tau ntawm cov neeg siv khoom sib txawv, thiab tsis muaj qhov sib npaug ntawm cov khoom xyaw.
Polycarboxylic acid dej txo tus neeg sawv cev masterbatch, feem ntau hu ua niam cawv. Feem ntau, nws tau los ntawm kev sib txuas cov monomers loj, me me monomers, stimulators, pib thiab saw hloov cov neeg sawv cev los ntawm dropwise synthesis.
Muaj ntau hom monomers loj, xws li APEG, MPEG, HPEG, TPEG, IPEG, thiab lwm yam.
Cov monomers me me muaj nyob hauv cov pob txha molecular, suav nrog acrylic acid, methacrylic acid, fumaric acid, maleic anhydride thiab lwm yam.
Lub ntsiab Cheebtsam ntawm polycarboxylic acid dej txo tus neeg saib xyuas niam cawv yog loj monomers, feem ntau siv HPEG thiab TPEG. Qhov feem ntau yog ntau tshaj 30%.
Polycarboxylic acid synthesis khoom, muab niam cawv synthesis technology. Cov khoom tseem ceeb yog monomer, raws li lwm cov ntaub ntawv, feem ntau hais lus, ntau npaum li cas cov khoom ntawm niam cawv yog, cov ntsiab lus ntawm cov khoom yog hais txog cov ntsiab lus ntawm cov khoom, cov dej txo tus neeg sawv cev kuj yog raws li niam cawv ntxiv rau cov khoom me me thiab cov dej sib xyaw.
