Katundu wofunika kwambiri wama ethel ethel solul ndi katundu wake. Makhalidwe apadera a mitundu yambiri ya cellulose amawapangitsa kuti azigwiritsa ntchito minda yosiyanasiyana, komanso kuphunzira za miyambo ndi kopindulitsa minda yatsopano yofunsira kapena kusintha kwa magawo ena a ntchito. Ling kuchokera ku Shanghai jiao jiao chon yunivesite adachita kafukufuku watsatanetsatane paCarboxymethylcellulose (CMC), kuphatikizapo kapangidwe ka kayendedwe ka masentimita kwa masentimita (kulemera kwa maselo ndi kuchuluka kwa zolowa m'malo), pH yamitundu, ndi mphamvu ya Ionic. Zotsatira zofufuzira zikuwonetsa kuti kusinthika kwa ziro Kuchulukitsa kwa kuchuluka kwa kuchuluka kwake kumatanthauza kukula kwa mawonekedwe a matonyo, komanso kukopeka kosavuta pakati pa mamolekyulu kumawonjezera mawidwe a yankho; Mulingo waukulu wazokhazikika umapangitsa ma molekyulu atatambasulira kwambiri yankho. Boma lilipoli, voliyumu ya hydroynamic imakhala yayikulu, ndipo mavuwo amakhala akulu. Makutu a cmc am'madzi amawonjezeka ndi kuchuluka kwa ndende, komwe kumakhala ndi ma viscoelaus. Makulidwe a njirayi amachepetsa ndi mtengo wa pH, ndipo ikatsika kuposa mtengo winawake, mafayilo amachulukana pang'ono, ndipo pamapeto pake asidi amapangidwa ndikupangika. CMC ndi polymeric polymer, powonjezera mafuta a Monovavalevale con +, khiriki, chidwi chimachepa. Kuphatikiza kwa CAT CAT CAZ + kumapangitsa kuti mamasukidwe athe kuchepera kenako ndikukula. Pamene ndende ya Ca2 + ndiyokwera kuposa malo achibachi, mamolekyu a CMC amalumikizana ndi Ca2 +, ndipo maluso opanga zikhulupiriro. Liang Yaqin, North University of China, etc. Zotsatira zofufuzira zinapezeka kuti: Mauwu owoneka bwino a CATIC hydroththyl cellulose yokhala ndi cholowa chazolowa kuposa momwe zimakhalira ndi cydroxethyl celluuse. . Mu ndende inayake ya mchere, cheke kuwoneka kuti zikuchepera ndi kuwonjezeka kwa kuchuluka kwa kusamalira mchere. Pansi pa chimbudzi chomwecho, mawonekedwe owoneka a Chec mu CACL2 Dongosolo la yankho limakhala lokwera kwambiri kuposa chec munthawi ya Nacl.
Ndi kuyang'ana mosalekeza za kufufuza kwa ntchito, katundu wa njira zosakanikirana dongosolo lopangidwa ndi cellulose yosiyanasiyana alandila chidwi cha anthu. Mwachitsanzo, sodium carboxymethyl cellulose (nacmc) ndi hydroxethyl cellulose (hec) kugwiritsidwa ntchito kwamphamvu kwa mafuta, koma zotsatira za kuwononga zachilengedwe, koma zomwe zimagwiritsidwa ntchito zokhazokha sizoyenera. Ngakhale kale anali ndi mawonekedwe abwino, amakhudzidwa mosavuta ndi kutentha kwa nthawi yosungirako ndi mchere; Ngakhale omalizirayo ali ndi kutentha kwabwino komanso kukana mchere, luso lake lotukuka ndi losauka ndipo mlingo wake ndi waukulu. Ofufuzawo adasakaniza mayankho awiriwo ndikupeza kuti mawonekedwe a yankho la comptite adayamba kukula, kutentha kutentha kwa kutentha ndi kusagwirizana ndi mchere kukana. PRIca SovilJ et al. aphunzirapo zachiwerewere za njira yosakanikirana ya dongosolo la HPMC ndi NACMC ndi Anionic zochulukitsa. Khalidwe lachiberekero la dongosolo limatengera HPMC-nacmc, hpmc-sds ndi ma nacmc- (ma hpmucts) osiyanasiyana omwe adachitika pakati.
Mitundu yazachinyengo ya ethel ethel etheluse imakhudzidwanso ndi zinthu zosiyanasiyana, monga zowonjezera, mphamvu zamakina kunja ndi kutentha kwamphamvu. Tomoaki HINO et al. Kuphunzira zotsatirazi kuphatikizira kwa chikonga pazachilengedwe cha hydroxypylllulose. Pa 25C ndi kutsika kotsika kuposa 3%, hpmc yowonetsa madzi a Newtonia. Pamene Nikotine adawonjezeredwa, mafakisoniwo adachuluka, zomwe zidawonetsa kuti nikotine idakulaHpmcmamolekyulu. Nicotine pano akuwonetsa zoyipa zomwe zimakweza mfundo ya gel selo ndi chifunga cha HPMC. Mphamvu monga mphamvu ngati mphamvu ya Shear idzakhalanso ndi mphamvu ina pa katundu wa cellulose ethel ether magazi. Kugwiritsa ntchito Rheologir Turbimeter ndi Chida Chaung'ono Kuchepetsa, zimapezeka kuti muyeso wachepetsani, chifukwa chometa ubweya, chifukwa kutentha kusakanikirako, kutentha kosintha kwa mfundo za chifunga kumachuluka.
