1.Ukusetha isikhathi
I-cellulose ether inomphumela othile wokuvinjelwa kodaka. Njengoba okuqukethwe kwe-cellulose ether kwanda, isikhathi sokumisa udaka sibuye sinwebe. Umthelela wokuhlehlisa we-cellulose ether ku-slurry usimende ngokuyinhloko uncike ezingeni lokushintsha i-alkyl, futhi awuhlobene eduze nesisindo sayo samangqamuzana. Ukuncipha kwezinga lokushintshwa kwe-alkyl, kukhulu okuqukethwe kwe-hydroxyl, futhi kuba sobala kakhulu umphumela wokubambezeleka. Ngaphezu kwalokho, ngokuqukethwe okuphezulu kwe-cellulose ether, ungqimba lwefilimu oluyinkimbinkimbi lunomthelela obaluleke kakhulu ekubambezelekeni kokuqala kwe-hydration kasimende, ngakho-ke, umphumela wokubuyisela emuva ubonakala nakakhulu.

2.Amandla okugoba namandla acindezelayo
Ngokuvamile, amandla angenye yezinkomba zokuhlola ezibalulekile zomphumela wokwelapha wezinto zikasimende ezisekelwe kusimende kuzingxube. Ukwanda kokuqukethwe kwe-cellulose ether kuzonciphisa amandla okucindezela namandla okuguquguquka kodaka.

3. Amandla ebhondi
I-Cellulose ether inomthelela obalulekile ekusebenzeni kokubopha kodaka. I-Cellulose ether yakha ifilimu ye-polymer enomphumela wokuvala phakathi kwezinhlayiya ze-cement hydration ohlelweni lwesigaba se-liquid, okukhuthaza inani elikhulu lamanzi efilimu ye-polymer ngaphandle kwezinhlayiya ze-cement, ezivumela ukugeleza okuphelele kukasimende, ngaleyo ndlela kuthuthukise ukubopha. amandla e-slurry eqinile. Ngesikhathi esifanayo, inani elifanele le-cellulose ether lithuthukisa ipulasitiki kanye nokuguquguquka kodaka, linciphisa ukuqina kwendawo yoguquko phakathi kodaka kanye nesixhumi esibonakalayo se-substrate, futhi kunciphise ikhono lokushelela phakathi kwezindawo zokusebenzelana. Ngokwezinga elithile, ithuthukisa umphumela wokubopha phakathi kodaka ne-substrate. Ngaphezu kwalokho, ngenxa yokuba khona kwe-cellulose ether ku-slurry kasimende, indawo ekhethekile yokuguqula isikhombimsebenzisi kanye nesendlalelo esibonakalayo kwakhiwa phakathi kwezinhlayiya zodaka kanye nemikhiqizo ye-hydration. Lesi sendlalelo esisebenzisanayo senza indawo yokuguqula isixhumi esibonakalayo ibe lula futhi ingaqini, ngaleyo ndlela inikeze udaka amandla okubopha aqinile.
