pob zeb ua Kev tsim kho Superplasticizer
May 18, 2020
Vim tias cov nplaim superplasticized sib xyaw, tshwj xeeb tshaj yog ntws superplasticized hmoov sib xyaw, muaj cov khoom ntim sib xyaw ntau ntawm cov tshuaj khib, lawv zoo li cov nplaum. Cov qhob rub tawm los yog cab rau ntawm lub pob tw, cov kua muag saum npoo thiab cov khoom sib xyaw zoo nkaus li txav tau qis dua hauv qhov ua tiav' s qhov hnyav. Kev siv coarser nplua zoo lossis qhov sib faib ntau dua ntawm cov ntxhib ntxoo sib xyaw stiffens qhov sib xyaw ua ke thiab muab cov phom sij-qhov muag kom pom hnyav dua. Lwm txoj kev hais daws tsuas yog ncua sij hawm xaus. Lub superplasticizer tsis yog kho-txhua qhov admixture; nws muaj nws tus kheej cov teeb meem, uas yuav tsum tau coj mus rau hauv tus account. Txawm li cas los xij, txoj kev hloov pauv ntawm cov pob zeb uas tsis ruaj khov mus rau cov pob zeb ua dej ntxiv los ntawm kev ntxiv cov neeg ua haujlwm rau dej hloov chaw cov dej yuav yog qhov tseem ceeb tshaj plaws hauv kev tsim cov cuab yeej technology txij li kev tsim cov huab cua nkag.
