1. Intshayelelo ye-cellulose ether:
Ubume beMichiza: I-cellulose ethers ziipolymers ezinyibilikayo zamanzi eziphuma kwi-cellulose, i-polysaccharide yendalo efumaneka kwiindonga zeeseli zesityalo. Iqukethe ukuphindaphinda iiyunithi ze-glucose ezidityaniswe ngamabhondi e-β-1,4-glycosidic.
I-Hydrophilicity: I-Cellulose ether yi-hydrophilic, nto leyo ethetha ukuba inobudlelwane olomeleleyo namanzi.
2. Indima ye-cellulose ether kudaka:
Ukugcinwa kwamanzi: Omnye weyona misebenzi iphambili ye-cellulose ether kudaka kukuphucula ukugcinwa kwamanzi. Yenza ifilimu ebhityileyo ejikeleze amasuntswana e-samente, inciphisa ukuphuphuma kwamanzi kunye nokuqinisekisa inkqubo ende ye-hydration.
Ukuphucula ukusebenza: I-ether ye-cellulose isebenza njenge-rheology modifier ukuphucula ukusebenza kodaka. Oku kubaluleke ngakumbi kwizicelo ezifana nokutyabeka kunye nokunikezela.
3. Impembelelo kumthamo wodaka:
Ukufunxwa kwamanzi: Ubume be-hydrophilic be-cellulose ethers bubenza bakwazi ukufunxa amanzi kumxube. Njengoko isanda, umthamo wamanzi opheleleyo kumdaka uyanda, obangela ukwanda komthamo.
Ukungena emoyeni: Ukongeza i-cellulose ethers kunokungenisa umoya kudaka. Amaqamza omoya abanjiweyo anegalelo ekufumaneni umthamo.
Ubume bePore: I-cellulose ethers inokuchaphazela i-microstructure yodaka, yenze inethiwekhi eninzi. Olu tshintsho kwisakhiwo se-pore kubangela ukunyuka okukhulu komthamo.
I-4. Inkqubo yokukhutshwa kwamanzi kunye nokwandiswa kwevolumu:
Ukulibaziseka kwe-hydration: I-cellulose ethers inokucothisa inkqubo yokufakwa kwesamente. Oku kulibaziseka kwe-hydration kuvumela ukuhanjiswa okuthe kratya kwamanzi ngaphakathi kodaka, okunokubangela ukwanda komthamo.
Umphumo wokunyanga: Ukugcinwa kwamanzi okwandisiweyo okukhuthazwa yi-cellulose ethers kunceda ukwandisa ixesha lokunyanga, ukuvumela amaqhekeza e-samente ukuba abe ne-hydrate ngokupheleleyo kwaye achaphazele umthamo wokugqibela wodaka.
5. Ukusebenzisana nezinye izithako:
Ukusebenzisana kwe-binder: I-ethers ye-cellulose isebenzisana nezibophelelo zesamente ukwenza i-matrix ezinzileyo. Le ntsebenziswano ichaphazela ukulungelelaniswa kweengqungquthela kwaye ikhokelela ekwandiseni umthamo.
I-Admixture synergy: Ukuba i-cellulose ethers isetyenziswa kunye nezinye izixube, impembelelo ye-synergistic ingenzeka, echaphazela umthamo opheleleyo wodaka.
6. Ukusasazwa kunye nokuhanjiswa kwesuntswana:
Ukusasazwa okulinganayo: Xa i-ether ye-cellulose ihlakazwe ngokufanelekileyo kwi-mortar, inokwenza ukuhanjiswa kwe-particle kufana kakhulu. Oku kufana kuchaphazela ukuxinana kokupakisha kwaye ngaloo ndlela umthamo wodaka.
7. Iimeko zokusingqongileyo:
Ubushushu kunye nokufuma: Iimeko zokusingqongileyo ezifana neqondo lobushushu kunye nokufuma kunokuchaphazela ukuziphatha kwe-cellulose ethers kudaka. Ukudumba kunye neempawu zokufunxa amanzi zinokuhluka phantsi kweemeko ezahlukeneyo zokusingqongileyo, ezichaphazela umthamo.
8. Isiphelo:
Isishwankathelo, ukonyuka komthamo okuqatshelwe ukongezwa kwe-cellulose ethers kumdaka sisiphumo sokusebenzisana okuntsokothileyo kubandakanya ukuthatyathwa kwamanzi, ukulibaziseka kwe-hydration, ukungena komoya, kunye notshintsho kwi-microstructure yodaka. Ukuqonda ezi ndlela kubalulekile ukongeza ukusetyenziswa kwe-cellulose ethers kwimixube yodaka kunye nokufezekisa iipropati ezinqwenelekayo kwizicelo zokwakha.
