1.Ho beha nako
Cellulose ether e na le phello e itseng ea ho fokotsa seretse.Ha litaba tsa cellulose ether li ntse li eketseha, nako ea ho beha seretse e boetse e lelefatsa.Phello e fokolisang ea cellulose ether ho slurry ea samente haholo-holo e itšetlehile ka tekanyo ea ho fetola alkyl, 'me ha e amane haufi-ufi le boima ba eona ba molek'hule.Ha boemo ba alkyl substitution bo le tlase, boteng ba hydroxyl bo eketseha, 'me ho hlakile haholoanyane phello ea ho lieha.Ho feta moo, ka lintho tse ngata tsa cellulose ether, lera le rarahaneng la filimi le na le phello e kholo ea ho lieha ho phalla ha samente pele ho nako, ka hona, phello ea ho lieha e boetse e totobetse haholoanyane.

2.Ho kobeha matla le matla a ho hatella
Hangata, matla ke e 'ngoe ea matšoao a bohlokoa a tlhahlobo bakeng sa pholiso ea lisebelisoa tsa samente tse thehiloeng ho samente metsoakong.Ho eketseha ha litaba tsa cellulose ether ho tla fokotsa matla a khatello le matla a flexural a seretse.

3. Matla a tlamo
Cellulose ether e na le phello e kholo ts'ebetsong ea tlamahano ea seretse.Cellulose ether e etsa filimi ea polymer e nang le phello ea ho tiisa pakeng tsa likaroloana tsa samente hydration tsamaisong ea mokelikeli, e khothalletsang metsi a mangata ka filimi ea polymer ka ntle ho likaroloana tsa samente, e leng se loketseng ho hydration e feletseng ea samente, ka tsela eo ho ntlafatsa bonding. matla a seretse se thatafetseng.Ka nako e ts'oanang, tekanyo e loketseng ea cellulose ether e ntlafatsa polasetiki le ho feto-fetoha ha seretse, ho fokotsa ho tiea ha sebaka sa phetoho pakeng tsa seretse le sebopeho sa substrate, le ho fokotsa bokhoni ba ho thella pakeng tsa li-interfaces.Ho isa bohōleng bo itseng, e ntlafatsa phello ea maqhama pakeng tsa seretse le substrate.Ho phaella moo, ka lebaka la ho ba teng ha cellulose ether ka slurry ea samente, sebaka se khethehileng sa phetoho ea segokanyimmoho le lera la sehokelo li thehoa pakeng tsa likaroloana tsa seretse le lihlahisoa tsa hydration.Lera lena la segokanyimmediamentsi sa sebolokigolo se etsa hore sebaka sa phetoho ya segokanyimmediamentsi se fetofetohe le hore se se ke sa tiya, ka hona se fa seretse matla a matla a ho kopanya.
