Kev tsom xam ntawm qhov ua rau tsis tseeb coagulation:

Qhov tshwm sim ntawm qhov tsis tseeb coagulation feem ntau yog ntaus nqi rau ntau yam. Ua ntej tshaj plaws, thaum cov ntsiab lus ntawm qee cov khoom hauv cov cement, tshwj xeeb tshaj yog aluminates los yog sulfates, siab dhau lawm, cov khoom no yuav hnov ​​​​mob sai sai nrog dej, ua rau cov pob zeb poob fluidity nyob rau lub sijhawm luv luv. Qhov thib ob, qhov zoo ntawm cov cement kuj yog ib qho tseem ceeb cuam tshuam rau qhov chaw tsis raug. Cov cement zoo heev yuav ua rau thaj chaw tshwj xeeb thiab ua rau thaj chaw sib cuag nrog dej, yog li ua kom cov tshuaj tiv thaiv ceev thiab ua rau muaj qhov tsis tseeb. Tsis tas li ntawd, kev siv cov khoom siv tsis zoo kuj yog ib qho ua rau. Piv txwv li, dej-txo admixtures react chemically nrog tej yam Cheebtsam nyob rau hauv cement los tsim insoluble tshuaj. Cov tshuaj insoluble no yuav nqus dej ntau, ua rau txo cov dej ntawm cov pob zeb. Cov xwm txheej xws li kub thiab av noo nyob rau hauv ib puag ncig kev tsim kho kuj tuaj yeem cuam tshuam qhov fluidity ntawm cov pob zeb, ua rau tsis muaj teeb meem.

Txoj kev daws teeb meem ntawm qhov tsis tseeb coagulation yog raws li hauv qab no:

Ua ntej tshaj plaws, ua haujlwm nyuaj rau kev xaiv cov cement. Ntau hom cement sib txawv muaj cov tshuaj sib txawv thiab cov yam ntxwv reactive, yog li nws yog ib qho tseem ceeb uas yuav tsum xaiv cov cement ntau yam uas tsis tshua muaj peev xwm ua rau qhov teeb meem tsis tseeb. Los ntawm kev ua tib zoo tshuaj xyuas thiab kev sim, peb tuaj yeem pom cov cement uas zoo tshaj plaws rau cov kev xav tau ntawm txoj haujlwm tam sim no, yog li txo qis kev pheej hmoo ntawm kev teeb tsa tsis raug.

Qhov thib ob, peb kuj yuav tsum tau ceev faj heev thaum siv cov khoom sib xyaw. Cov khoom sib xyaw tsim nyog tuaj yeem txhim kho kev ua haujlwm ntawm pob zeb, tab sis yog tias siv tsis raug lossis yog tias cov khoom siv tsis sib haum nrog cov cement raug xaiv, teeb meem teeb meem yuav tshwm sim. Yog li ntawd, peb yuav tsum tau kho cov hom thiab ntau npaum li cas ntawm admixtures raws li tej yam kev mob ntawm peb tes num thiab cov yam ntxwv ntawm cov cement, los yog optimize lawv cov kev ua tau zoo los ntawm compounding los xyuas kom meej tias cov pob zeb muaj peev xwm tuav tau zoo fluidity.

Thaum kawg, qhov kub ntawm qhov kev tsim kho ib puag ncig kuj yog ib qho tseem ceeb cuam tshuam rau lub fluidity ntawm pob zeb. Nyob rau hauv ib qho chaw kub kub, cov dej hauv pob zeb evaporates yooj yim, ua rau cov pob zeb ua kom khov sai. Yuav kom daws tau qhov teeb meem no, peb tuaj yeem ntsuas ntsuas qhov sib xyaw kom qis, xws li ua ntej txias qhov sib xyaw ua ntej sib tov, lossis siv dej khov rau kev sib tov. Los ntawm kev txo qhov kub thiab txias, peb tuaj yeem ua kom qeeb ntawm qhov chaw nrawm ntawm pob zeb, yog li zam qhov tshwm sim ntawm qhov teeb meem tsis tseeb.
