Isikhathi soku- #etting
I-Cellulose Ether inomphumela othile wokubuyisa odaka. Njengoba okuqukethwe kwe-cellulose ether kuyanda, isikhathi sokubeka udaka futhi sanda. Umphumela wokugcina kabusha we-cellulose ether ku-Cement Slurry ikakhulukazi kuya ngezinga lokufaka esikhundleni se-Alkyl, futhi ahlobene kakhulu nesisindo sawo se-molecular. Ukwehlisa izinga le-Alkyl Exfunce, kukhudlwana okuqukethwe kwe-hydroxyl, futhi okusobala okusobala okusobala. Ngaphezu kwalokho, ngokuqukethwe okuphezulu kwe-cellulose ether, ungqimba lwefilimu oluyinkimbinkimbi lunomphumela obaluleke kakhulu ekubambezeleni i-hydration yokuqala ka usimende, ngakho-ke, umphumela wokugcina kabusha uyabonakala futhi.

2.Ngamandla amandla namandla acindezelayo
Imvamisa, amandla kungenye yezinkomba ezibalulekile zokuhlola umphumela wokuvuka kwezinto zokwenziwa kosimende osuselwa kuso usimende osuselwa ku-cements on mixtures. Ukwanda kokuqukethwe kwe-cellulose ether kuzonciphisa amandla acindezelayo namandla aguqukayo odaka.

3. Amandla eBond
I-Cellulose Ether inomthelela omkhulu ekusebenzeni kwebhondi ngodaka. I-Cellulose Ether yakha ifilimu ye-polymer ngomphumela wokuvalwa kwezimpawu zokubopha phakathi kwesistimu yesimende esimisweni sesigaba se-polymer ngaphandle kwesimende, ngaleyo ndlela kuthuthukise ukubopha isibopho amandla e-slurry elukhuni. Ngasikhathi sinye, inani elifanele le-cellulose etre lenyusa i-plastity kanye nokuguquguquka kodaka, kunciphisa ukuqina kwendawo yokuguqula phakathi kodaka kanye nesibonisi se-substrate, kanye nokunciphisa amandla okuslayidi phakathi kwezindawo zokuxhumana. Ngokwezinga elithile, kuthuthukisa umphumela wokubopha phakathi kodaka noxhaso. Ngaphezu kwalokho, ngenxa yokuba khona kwe-cellulose ether ku-Cement Slurry, indawo ekhethekile yokuguqula isimo kanye nesendlalelo se-interface senziwa phakathi kwezinhlayiya zombusi nemikhiqizo ye-hydration. Lolu handla lwe-interface lwenza indawo yokuguqulwa kwesimo esibonakalayo iguqulwe kakhudlwana futhi iqinile, ngaleyo ndlela inikeze amandla okuqinisa ngamandla.
