1.Ukuseta ixesha
I-ether ye-cellulose inesiphumo esithile sokunciphisa udaka.Njengoko umxholo we-cellulose ether ukhula, ixesha lokumisela lodaka nalo liyakwandisa.Isiphumo esibambekayo se-cellulose ether kudaka lwesamente ikakhulu sixhomekeke kwiqondo lokutshintshwa kwe-alkyl, kwaye ayinxulumananga ngokusondeleyo nobunzima bayo bemolekyuli.Okukhona usezantsi iqondo lealkyl endaweni, kokukhona umxholo omkhulu wehydroxyl, kwaye kokukhona kucaca ngakumbi isiphumo sokubambezela.Ngaphezu koko, ngomxholo ophezulu we-cellulose ether, umaleko wefilimu oyinkimbinkimbi unempembelelo ebaluleke ngakumbi ekubambezelekeni kwe-hydration yokuqala ye-samente, ngoko ke, umphumo wokubuyisela ubonakala ngakumbi.

2.Ukugoba amandla kunye namandla oxinzelelo
Ngesiqhelo, amandla sesinye sezalathisi zovavanyo olubalulekileyo lwesiphumo sokunyanga semathiriyeli esekwe kwisamente kwimixube.Ukunyuka kumxholo we-cellulose ether kuya kunciphisa amandla oxinzelelo kunye namandla okuguquguquka komdaka.

3. Amandla ebhondi
I-ether ye-cellulose inempembelelo ebalulekileyo ekusebenzeni kokubambisana kodaka.I-cellulose ether yenza ifilimu ye-polymer enefuthe lokutywinwa phakathi kweengqungquthela ze-sement hydration kwinkqubo yesigaba se-liquid, ekhuthaza ubuninzi bamanzi kwifilimu ye-polymer ngaphandle kweengqungquthela ze-cement, ezihambelana ne-hydration epheleleyo ye-cement, ngaloo ndlela iphucula i-bonding. amandla odaka oluqinileyo.Kwangaxeshanye, isixa esifanelekileyo se-cellulose ether sonyusa iplastiki kunye nokuguquguquka kodaka, ukunciphisa ukuqina kwendawo yokutshintsha phakathi kodaka kunye ne-interface ye-substrate, kunye nokunciphisa ukukwazi ukutyibilika phakathi kwe-interfaces.Ukuya kumlinganiselo othile, yongeza isiphumo sokuhlangana phakathi kodaka kunye ne-substrate.Ukongezelela, ngenxa yobukho be-cellulose ether kwi-sement slurry, indawo ekhethekileyo yokutshintshwa kwendawo kunye ne-interface layer yenziwa phakathi kweengqungquthela zodaka kunye neemveliso ze-hydration.Lo maleko wojongano lwenza indawo yotshintsho yojongano ibe bhetyebhetye kwaye ingaqina kancinci, ngaloo ndlela inika udaka amandla okuqina okuqina.
