Impahla ebaluleke kakhulu ye-Celsulose Ether Solution iyimpahla yayo ye-rherological. Izakhiwo ezikhethekile ze-Jeelsosocological Afers zibenza basetshenziswe kabanzi emikhakheni ehlukahlukene, futhi ukutadisha izimbobo zensimbi kunenzuzo ekuthuthukisweni kwezinkambu ezintsha zohlelo lokusebenza noma ukuthuthukiswa kwezinye izinkambu zohlelo lokusebenza. Li Jing waseShanghai Jiao Tong University wenze isifundo esihlelekile ezakhiweni ze-rheological zeI-Carboxymethylcellellulose (CMC), kufaka phakathi ithonya lamapharamitha we-cmc ahlulekile we-CMC (isisindo samangqamuzana kanye nesilinganiso sokufakwa esikhundleni), ukugxila pH, namandla ionic. Imiphumela yocwaningo ikhombisa ukuthi i-zero-shear viscosisity yesisombululo inyuka ngokwanda kwesisindo se-molecular kanye nezinga lokufaka esikhundleni. Ukwanda kwesisindo se-molecular kusho ukukhula kwamaketanga ama-molecular, kanye nokufakwa okulula phakathi kwama-molecule kukhulisa ukubonana kwesixazululo; Izinga elikhulu lokufaka esikhundleni senza ama-molecule anwebe ngaphezulu kusisombululo. Umbuso ukhona, ivolumu yeHydrodynamic inkulu kakhulu, futhi i-visa iba nkulu. I-viscosity yesisombululo esinamanzi e-CMC inyuka ngokwanda kokuhlushwa, okune-viscoelastity. I-viscosity yekhambi iyancipha ngenani le-PH, futhi lapho liphansi kunenani elithile, i-viscosity inyuka kancane, futhi ekugcineni i-acid yamahhala yakhiwa futhi yanembe. I-CMC iyi-polymer ye-polyanionic, lapho ingeze ama-monosongent usawoti o sest na +, K + isihlangu, i-viscosity izokwehla ngokufanele. Ukungezwa kwe-caz ye-caz ehlukanisiwe + kubangela ukuba i-viscosity yesisombululo sokwehla kuqala bese iyanda. Lapho ukugcwala kwe-CA2 + kuphakeme kunephuzu le-stoichiometric, ama-molecule e-CMC asebenzisana ne-CA2 +, futhi i-superstrupture ikhona kwikhambi. I-Liang Yaqin, eNorth University of China, njll. Isebenzisa indlela yokubona i-Viscometer kanye nendlela yokujikeleza okujikelezayo ukwenza ucwaningo olukhethekile ezinhlakeni zesimbozo se-Hydroxyethyyls (CHEC). Imiphumela yocwaningo yathola ukuthi: (1) I-Catics Hydroxyyethyl celtulose inokuziphatha okujwayelekile kwe-polyelecroctrictyte okujwayelekile emanzini amsulwa, futhi ukubonakala okuncishisiwe kukhuphuka ngokwanda kokuhlushwa. Ukubonakaliswa okungaphakathi kwe-cationic hydroxyyethyl celtulose ngezinga eliphakeme lokufaka esikhundleni kukhulu kunalokho kwe-catioc hydroxyethyl cellulose enezinga eliphansi lokungena esikhundleni. . Ekuqoqweni kwesawoti okuthile, i-chec esibonakalayo visa incipha ngokwanda kokuhlushwa usawoti owengeziwe. Ngaphansi kwezinga elifanayo le-vear, i-visa elibonakalayo le-Chec ku-CCL2 Solution System liphakeme kakhulu kunale chec kuhlelo lwekhambi le-NACL.
Ngokujula okuqhubekayo kocwaningo kanye nokunwetshwa okuqhubekayo kwezinkundla zohlelo lokusebenza, izakhiwo zezisombululo zohlelo ezixubile ezakhiwa izipho ezihlukile zeselula zithole ukunakwa kwabantu. Isibonelo, i-sodium carboxyyllls (NACMC) ne-hydroxyethyl cellulose (HEC) zisetshenziswa njenge-ejenti yokudutshulwa kawoyela ezindaweni zokulwa namafutha, ezinokungcola okunamandla kwezemvelo kanye nokungcoliswa okuncane kwezemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wezemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa wemvelo, kepha umphumela wokuzisebenzisa. Yize okwedlule kunokubonakala okuhle, kuthinteka kalula ekushiseni kwama-reservoir kanye nosawoti; Yize lezokugcina inokushisa okuhle nokumelana nosawoti, amandla ayo okuqina ampofu futhi umthamo muhle kakhulu. Abaphenyi baxuba izixazululo ezimbili bathola ukuthi ukubonwa kwekhambi eliyinhlanganisela kwaba mkhulu, ukumelana namazinga okushisa kwathuthukiswa ngezinga elithile, futhi umphumela wokufaka isicelo wathuthukiswa. Verica sovilj et al. Ufunde indlela yokuziphatha kwesixazululo sesixazululo sohlelo oluxubile olwakhiwe nge-HPMC ne-NACMC kanye ne-anionic survic nge-visecome eshintshashintshayo. Ukuziphatha okunothando kohlelo kuncike ku-HPMC-NACMC, HPMC-SDS kanye ne-NACMC- (HPMPSS-S) imiphumela ehlukene eyenzekile phakathi.
Izakhiwo ze-Rheological of Cellulose Eter Solutions nazo zithinteka ezintweni ezahlukahlukene, njengezengezo, amandla okushisa angaphandle. Tomoaki hino et al. wafunda umphumela wokungezwa kwe-nicotine kwizakhiwo ze-bheological ze-hydroxypropylylylyllose. Ku-25c kanye nokuhlushwa okungaphansi kuka-3%, i-HPMC yakhombisa ukusebenza kweNewtonian fluid. Lapho kufakwa i-nicotine, ukubonakala kwandiswe, okuveze ukuthi i-nicotine yandisa ukufakwa kweI-HPMCama-molecule. I-nicotine lapha ikhombisa umphumela we-salting ophakamisa iphuzu le-gel nephuzu le-hpmc. Amandla okwenziwa ngoMeshini anjengebutho le-shear azoba nethonya elithile ezingxenyeni zekhambi le-cellulose ether. Isebenzisa insimbi ye-healogical turbidimeter kanye nethuluzi elincane lokusakazeka lokuhlaziywa kwe-angle, litholakala ukuthi kwikhambi le-semi-dilite, ukukhulisa izinga le-shear, ngenxa yokuxuba okusheshayo, izinga lokushisa lenkohliso lenkungu lizokwanda.
