Cellulose ether cuam tshuam rau mortar cua cov ntsiab lus thiab cement hydration

Cellulose ether feem ntau yog siv los ua ib qho ntxiv hauv cov tshuaj khib thiab cov pob zeb sib xyaw kom txhim kho lawv cov khoom. Thaum ntxiv rau cov tshuaj khib nyiab sib tov, cellulose ether tuaj yeem cuam tshuam rau ob qho tib si huab cua thiab cov dej ntawm cov cement.

Cellulose ether yog cov dej-soluble polymer uas muaj peev xwm khaws dej siab. Qhov no txhais tau tias nws tuaj yeem tuav cov dej molecules thiab tiv thaiv lawv los ntawm evaporating, uas yuav pab kom cov mortar sib tov ua haujlwm tau ntev dua. Yog li ntawd, cov ntsiab lus ntawm huab cua nyob rau hauv mortar tuaj yeem txhim kho, vim tias cov cellulose ether yuav pab txo qis cov huab cua uas ploj thaum sib tov thiab kev thauj mus los.

Tsis tas li ntawd, cellulose ether tuaj yeem cuam tshuam cov dej ntawm cov cement hauv cov tshuaj khib sib tov. Cement hydration yog cov tshuaj tiv thaiv uas tshwm sim ntawm cov dej thiab cov cement, uas ua rau tsim cov pob zeb tawv tawv. Cellulose ether tuaj yeem ua raws li tus neeg sawv cev retarding, uas ua rau qeeb tus nqi ntawm cov cement hydration. Qhov no tuaj yeem muaj txiaj ntsig zoo hauv qee qhov xwm txheej, xws li thaum ua haujlwm nrog kub lossis qhuav, qhov chaw ceev ceev ntawm cov mortar tuaj yeem ua rau tawg thiab lwm yam tsis xws luag.

Zuag qhia tag nrho, qhov sib ntxiv ntawm cellulose ether rau mortar tuaj yeem txhim kho nws txoj haujlwm, cov ntsiab lus ntawm huab cua, thiab cov cement hydration zog. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov teebmeem tshwj xeeb ntawm cellulose ether ntawm mortar yuav nyob ntawm seb hom thiab ntau npaum li cas ntawm cov khoom siv ntxiv, nrog rau cov khoom tshwj xeeb ntawm cov cement thiab lwm yam khoom hauv cov khoom sib xyaw.
