Muri minisiteri, selile ya selile igira uruhare mu gufata amazi, kubyimba, gutinda ingufu za sima, no kunoza imikorere yubwubatsi. Ubushobozi bwiza bwo gufata amazi butuma amazi ya sima arushaho kuba meza, arashobora kongera ubwiza bwamazi ya minisiteri itose, kongera imbaraga zo guhuza za minisiteri, no guhindura igihe. Ongeramo selile ether kuri mashini yo gutera imashini irashobora kunoza imikorere yo gutera cyangwa kuvoma hamwe nimbaraga zimiterere ya minisiteri. Cellulose ikoreshwa cyane nkinyongera yingirakamaro muri minisiteri ivanze. Dufashe umurima wibikoresho byubwubatsi nkurugero, selile ya selile ifite ibintu byiza cyane nko kubyimba, kubika amazi, no kudindiza. Kubwibyo, kubaka ibikoresho bya selile ya selile ikoreshwa cyane mugutezimbere umusaruro wa minisiteri ivanze (harimo minisiteri ivanze na minisiteri yumye), PVC resin, nibindi, irangi rya latex, putty, nibindi, harimo no gukora kubaka ibikoresho.
Cellulose irashobora gutinza inzira ya hydrata ya sima. Cellulose ether itanga minisiteri nibintu bitandukanye byingirakamaro, kandi ikanagabanya ubushyuhe bwambere bwa hydrata ya sima kandi bigatinda inzira ya hydrata dinamike ya sima. Ibi ntabwo ari byiza gukoresha ikoreshwa rya minisiteri mu turere dukonje. Izi ngaruka zo kudindira ziterwa na adsorption ya selile ya ether molekules ku bicuruzwa bitanga amazi nka CSH na ca (OH) 2. Bitewe no kwiyongera kwijimye ryumuti wa pore, selile ya selile igabanya umuvuduko wa ion mugisubizo, bityo bigatinda inzira yo gufata amazi. Iyo hejuru ya selulose ether yibikoresho bya minerval gel, niko bigaragara ingaruka zo gutinda kwa hydration. Cellulose ether ntabwo idindiza igenamigambi gusa, ahubwo inadindiza inzira yo gukomera ya sisitemu ya sima. Ingaruka zo kudindiza selile ya selile ntabwo ziterwa gusa nubunini bwayo muri sisitemu ya minerval gel, ahubwo binaterwa nimiterere yimiti. Urwego rwo hejuru rwa methylation ya HEMC, nibyiza ingaruka zo kudindiza selile. Ikigereranyo cyo gusimbuza hydrophilique nogusimbuza kongera amazi Ingaruka zo kudindiza zirakomeye. Nyamara, ubwiza bwa selulose ether ntacyo bugira kuri sima hydration kinetics.
Hamwe no kwiyongera kwa hydroxypropyl methylcellulose ether, igihe cyo gushiraho minisiteri cyiyongereye cyane. Hano hari isano ryiza ridafite umurongo hagati yigihe cyambere cyo gushiraho minisiteri nibiri muri selile ya ether, hamwe numurongo mwiza uhuza hagati yigihe cyanyuma cyo gushiraho nibiri muri selile ya ether. Turashobora kugenzura igihe cyo gukora cya minisiteri duhindura ingano ya selile.
