I-Cellulose Ether inokugcinwa kwamanzi okuhle kakhulu, okungavimbela umswakama kudaka olumanzi kusuka ekuhwamukeni ngaphambi kwesikhathi noma ukungeniswa yile nyalo, futhi ekugcineni ekugcineni kuqinisekisa izindawo zodaka, ezizuzisa kakhulu ku-data-ungqimba ongezansi kanye nezendlalelo zezisekelo zamanzi noma udaka owakhiwe ngaphansi kokushisa okuphezulu nezimo ezomile. Umphumela wokugcina amanzi we-cellulose ether ungashintsha inqubo yokwakha yendabuko futhi uthuthukise inqubekela phambili yokwakha. Isibonelo, ukwakhiwa kokulungiselela kungenziwa ezindaweni zokufaka amanzi ngaphandle kokumanzisa.
I-viscosity, umthamo, izinga lokushisa elikhona kanye nokwakheka kwamangqamuzana kwe-cellulose ether kunethonya elikhulu ekusebenzeni kwayo kokugcina amanzi. Ngaphansi kwezimo ezifanayo, kukhula okukhulu kwe-cellulose ether, okungcono ukugcinwa kwamanzi; Lapho kuphakama umthamo, ukugcinwa kwamanzi kangcono. Imvamisa, inani elincane le-cellulose ether lingathuthukisa kakhulu ukugcinwa kwamanzi kodaka. Lapho umthamo ufinyelela ezithile lapho izinga lokugcinwa kwamanzi likhuphuka lapho kwenzeka, umkhuba wamazinga okugcina amanzi uyancipha; Lapho izinga lokushisa elizwakalayo likhuphuka, ukugcinwa kwamanzi kwe-cellulose ether kuvame ukwehla, kepha ezinye izifelu eziguquliwe zibuye zibe nokugcinwa kwamanzi ngaphansi kwezimo eziphakeme zokushisa; Ama-Fibers anamazinga aphansi okufaka esikhundleni se-vegan ether anokusebenza okungcono kokugcinwa kwamanzi.
I-Hydroxyl Group e-Cellose Ether Molekyuli kanye ne-athomu ye-oxygen embonini wamanzi zizohlangana ne-molecule yamanzi ukwakha isibopho se-hydrogen, ngaleyo ndlela edlala indima enhle ekugcinweni kwamanzi; I-molecule yamanzi kanye ne-cellulose ether moleculat chain inflifffact ivumela ama-molecues amanzi ukuze afake ingaphakathi le-cellulose ether macromolecular chain futhi ancike emandleni aqinile abophayo, wakha amanzi aboshwe ngamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi, okuthuthukisa ukugcinwa kwamanzi kasimende; I-Cellulose Ether ithuthukisa i-Slurry entsha. Izakhiwo ze-Rheological, ukwakheka kwenethiwekhi ye-porous kanye nengcindezi ye-osmotic noma izakhiwo ezakha amafilimu ze-cellulose ether zivimbela ukuguquguquka kwamanzi.
I-Cellulose Ether ifaka ngodaka olumanzi olunokubonakala okuhle kakhulu, okungakhulisa kakhulu amandla obugqi phakathi kodaka olumanzi kanye nongqimba lwesisekelo, futhi kuthuthukise ukusebenza kwe-anti-sagging yodaka. Isetshenziswa kabanzi kudaka oluphamba, udaka lokubopha izitini nohlelo lwangaphandle oludongeni lokufakwa kodonga. Umphumela wokuqina we-cellulose ether ungakhulisa nekhono lokulwa nokuphambukiswa kanye ne-homogeneity yezinto zokwakha ezisanda kuxutshwa, vimbela ukunxuswa kwezinto ezibonakalayo, ukuhlukaniswa nokopha, futhi kungasetshenziswa ukhonkolo we-fiber, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kokhonkolo, ukhonkolo ongaphansi kwamanzi kanye nokhonkolo ongaziphathi kahle.
Umphumela wokuqina we-cellulose ether ngezinto zokwakha amasimende uqhamuka ekubonakaleni kwe-cellulose ether perher solution. Ngaphansi kwezimo ezifanayo, ukukhuphuka kwe-viscosiose ether, okungcono kakhulu kwento esuselwe kukhukhile usimende, kepha uma i-viscosity iphakeme kakhulu, izothinta uketshezi nokusebenza kwezinto ezibonakalayo ). Ukhonkolo ozimisele wodaka nokhonkolo ozimisele ngokuzihlanganisa, ezidinga ukufutheka okuphezulu, kudinga ukubonakala okuphansi kwe-cellulose ether. Ngaphezu kwalokho, umphumela wokuqina we-cellulose ether uzokwandisa ukufunwa kwamanzi kwezinto zokwakha amasimende futhi wandise isivuno sodaka.
I-viscosity ye-cellulose ether solution incike kulezi zinto ezilandelayo: isisindo samangqamuzana e-cellulose ether, ukugxila, izinga lokushisa, izinga lokuhlola kanye nendlela yokuhlola. Ngaphansi kwezimo ezifanayo, kukhula isisindo molecular of cellulose ether, okuphezulu kwendlela yekhambi; Lapho kukhuphuka khona ukugxila, kukhuphuka ukubonwa kwesixazululo. Lapho uyisebenzisa, ukunakekelwa kufanele kuthathwe ukugwema umthamo ngokweqile futhi kuthinte ukusebenza ngodaka nokhonkolo; I-Cellulose ETHE I-Viscotity yekhambi le-ether lizokwehla ngokunyuka kwamazinga okushisa, kanye nokuphakama okuphezulu, kuphoqelela kakhulu ithonya lokushisa; Isixazululo se-cellulose ether sivame ukuba yi-pseudoplastic fluid enendawo yokuncipha kwe-shear ngesikhathi sokuhlolwa, okuncane, ngakho-ke, ukubumbana kodaka kuzokwehla ngaphansi kwesenzo samandla angaphandle, okuzuzisa ukuklebhula ukwakhiwa kodaka, ukuze udaka lukwazi ukusebenziseka okuhle nokubumbana ngasikhathi sinye; Ngoba isixazululo se-cellulose ether yi-non-Newntonian ngoketshezi, lapho izindlela zokuhlola, izinsimbi zokuhlola noma izinsiza zokuhlola noma izindawo zokuhlola ezisetshenziselwa ukuvivinya i-viscosity zihlukile, imiphumela yokuhlola isixazululo esifanayo se-cellulose izohluke kakhulu.
Ama-molecule e-cellulose ether angalungisa ama-molecule wamanzi wezinto ezintsha ezibonakalayo ezingxenyeni ze-periphery of the cleach molecular, ngaleyo ndlela zandisa ukubuka kwesixazululo. Amaketanga ama-molelisar ather we-cellulose ahlanganiswa ukwakha isakhiwo senethiwekhi enezici ezintathu, ezokwenza nesixazululo saso esinamanzi anokuvunywa okuhle.
Isixazululo esiphakeme se-cellule Izisombululo ezinamanzi ze-methyl cellulose zivame ukuba ne-pseudoplastic ne-non-twixotropic fluority ngaphansi kwezinga lokushisa le-gel, kepha khombisa izakhiwo ze-Newtonian flow ezindaweni eziphansi ze-shear. I-Pseudoplaltity inyuka ngesisindo se-molecular noma ukugxila kwe-cellulose ether, kungakhathalekile ukuthi uhlobo lokungena esikhundleni kanye nesilinganiso sokufaka esikhundleni. Ngakho-ke, i-cellulose i-Teshers yebanga elifanayo lokubonana, noma ngabe i-MC, i-HPMC, i-hemc, izohlala ikhombisa izakhiwo ezifanayo zembongo inqobo nje uma ukugxila nokushisa kugcinwa njalo. Ama-Gels ahlelekile akhiwa lapho izinga lokushisa liphakama, futhi ukuhamba kakhulu kwe-thixotropic kwenzeka. Ukuhlushwa okuphezulu nokuvulekezwa okuphansi kuselula Le mpahla inzuzo enkulu kulungiswa kokulinganisa nokugcoba ekwakhiweni kokwakhiwa kodaka. Kudinga ukuchazwa lapha ukuthi ukukhuphuka kwendlela kaCellulose Ether, okungcono ukugcinwa kwamanzi, kepha kukhuphuka isisindo esiphakeme, kanye nokuncipha okuhlobene kwe-pullulose ether, kanye nokuncipha okuhambisanayo kwe-solubelity yayo, enomthelela omubi ekusebenzeni kokugxila kodaka nasekusebenzeni kokwakha. Lapho kukhuphuka khona i-viscosity, kusobala kakhulu umphumela wokuqina kudaka, kepha alufani ngokuphelele. Ukubonakaliswa okuphakathi nendawo okuphansi, kepha i-ether eguqulwe ngokuguqulwa inokusebenza okungcono ekuthuthukiseni amandla wesakhiwo sodaka lwamanzi. Ngokwanda kwe-viscosity, ukugcinwa kwamanzi kwe-cellulose ether kuyathuthuka.
