Raws li lub npe qhia, cement hydration yog tshuaj lom neeg cov tshuaj tiv thaiv tom qab sib tov sib xyaw ua ke thiab dej, lub xeev hmoov hloov mus rau hauv lub xeev cov dej uas muaj qhov kev sib khi, yog peb niaj hnub siv cov cement. Vim li ntawd txhim kho qee cov yam ntxwv ntawm cov cement, Kuv feem ntau ntxiv dej reducer thaum hydration.Bow peb yuav nkag siab txog lub taub lim dej reducer yuav muaj dab tsi cuam tshuam rau kev tso dej cement?
1. Txo cov nplaim hluav taws xob sab nraud thiab cov kua viscosity ntawm kev daws hauv cov cement slurry; Cov khoom ntaws tawm kev ntxhov siab thiab cov yas viscosity ntawm cement slurry yog txo.
2. Kev qhia ntawm huab cua nkag mus rau hauv cov txheej txheem tsim cov npuas npuas yog qhov pab cuam zoo rau cov dej ntws ntawm cov pob zeb ua tshiab;
3. Qhob ua kom dej txias tuaj yeem txo qis dej kom zoo thiab tso tawm kom sov ntawm cov pob zeb hauv av thiab txhim kho qhov ntim ruaj khov ntawm pob zeb.
4, ua qhov loj ntawm crystallization hais ntawm hydration khoom me, thiaj li txhawm rau txhim kho kev cog lus ntawm pob zeb ua ke, thiab tom qab ntawd txhim kho lub zog ntawm qhob.
Pob zeb ua kom dej tsim hluav taws xob rau cov chaw tsim khoom tau hais tias cov khoom lag luam los ntawm adsorption ntawm cov cement slurry thaj chaw ntawm cov teeb meem ntawm cov txiaj ntsig, qhov kev ua tau zoo ntawm cov cement tau txhim kho zoo heev, muaj peev xwm tiv thaiv qhov kev tsim kho ntawm ntau cov kev siv cov cement siv.Li cas, nws yuav tsum sau tseg tias qhov muab cov tshuaj yuav tsum tau ntsuas ua ntej ntxiv, thiaj li kom tsis txhob muaj qhov ntsuas tsis tsim nyog, ua rau cov hmoov av tsis ua haujlwm.
