1. Ubushushu be-hydration
Ngokwe-curve yokukhutshelwa kobushushu bokushisa ixesha elingaphezulu kwexesha, inkqubo ye-hydration yesamente idla ngokwahlukeneyo, ixesha lokuqalisa kunye nexesha lokuqalisa (i-super), kunye nexesha lokunyanga (1D ~ 28D).
Iziphumo zovavanyo zibonisa ukuba kwinqanaba lokuqala lokuqhelanisa (okt, ixesha le-hydration), xa inani le-HEMDY lithelekiswa ne-cerry engenanto, incindi ye-Exormic inyuke kakhulu. Xa inani leI-hemcUkunyuka ukuba ingaphezulu kwe-0.3%, i-fiethermic yokuqala ye-slourry ilithiyelwe, kwaye ixabiso le-Peak ngokuthe ngcembe linciphisa ukonyuka komxholo weHMM; Ngokuqinisekileyo i-HMC iya kulibazisa kakhulu ixesha lokuqhubela phambili kunye nexesha lokukhawulezisa lesamente, kwaye likhulu umxholo, ixesha elide lexesha lokufikelela, kunye nokuncipha kwenqanaba lokukhawulezisa; Utshintsho lwesiqulatho se-selsulose i-Eles ayinasiphumo esibonakalayo kubude bexesha lokukhohlisa kunye nexesha lokuzinza lingaphezulu kweeyure ezingama-36, kodwa xa iboniswe kumxholo we-stserase, enjengomfanekiso (B).

2. MIiPropathi ze-ECONCAL:
Ngokufunda iintlobo ezimbini zeSelesese Talupesies ezingama-60000 · spas kunye ne-100000pal, yafunyanwa ukuba amandla oxinzelelo ocociweyo ahluleke ngokuthe ngcembe ukwenziwa komxholo wayo. Amandla oxinzelelo ohlelo oluguqulweyo oxutywe ne-100000pasity viscofity i-HydroxylDolDl Methyl Seles Seles Sethel Setes Sethel Seles Setes yokuqala (njengoko kubonisiwe kumzobo 4). Ibonisa ukuba ukufakwa kwe-methyl sethele i-ether kuya kunciphisa kakhulu amandla obopha besamente. Okukhona isixa semali, amancinci amancinci aya kuba; Incinci i-vickosity, eyona nto ingaphezulu kwempumelelo yokuphulukana namandla odaka; I-HydroxyPOpyl Methyl Selelose Ether xa umthi wedosi ungaphantsi kwe-0.1%, amandla oxinzelelo akhule ngokufanelekileyo. Xa idosi ingaphezulu kwe-0.1%, amandla oxinzelelo odaka aya kuncipha ngokunyuka kwethamo, ke umthamo kufuneka ulawulwe nge-0.1%.

(I-Methyl Selerse, i-viscosity 60000pal, emva koko kubhekiswa kuyo njenge-MC1; I-MCYPOse ETER, i-viscosity ye-GETETHLLE, i-viscosity ye-100000pas, ekubhekiswa kuyo njenge-MC3).
3. Cixesha elininzi:
Ngokulinganisa ukuseta ixesha le-hydroxypropyl methylcelgalose ethe therpasity ye-100000pamo kwimitha eyahlukeneyo ye-HPMC, ixesha lokugqibela kunye nokusetshwa kwexesha lokwenza ixesha lokwenza ixesha lokuqina. Xa uxinzelelo luyi-1%, ixesha lokuqala lokufika lifikelela kwimizuzu emi-510, kwaye ixesha lokugqibela lokuseta lifikelela kwimizuzu engama-850. Xa kuthelekiswa nesampulu yendawo engenanto, ixesha lokuqala lokuseta liyandiswa ngemizuzu engama-210, kwaye ixesha lokugqibela lokuseta lindisiwe ngemizuzu engama-470 (njengoko kubonisiwe kumzobo 5). Nokuba yi-HPMC ngohlobo lwe-50000pa s, i-100000pa s okanye i-200000pa s, inokulibazisa ixesha lokuphumla, njengoko kubonisiwe kumzobo 6 obonisiweyo. Kungenxa yokuba i-Ersulose Ether i-ersed i-arsed kumphezulu wamasuntswana wesamente, ethintela amanzi ekunxibelelaneni neesamente, ngaloo ndlela ulibazele i-hydration yesamente. Owona mkhulu we-viscosity ye-fesuplose ether, umkhuseli we-adsorption therption kumphezulu wamasuntswana wesamente, kunye nefuthe elibalulekileyo ngakumbi.

Umzobo
(MC-5 (50000), mc-10 (100000 · s) kunye ne-MC-20 (200000 · s))
I-Methyl Selethe i-Ether kunye ne-hydroxypropyl metyl seluplose i-ether isuti iyandisa ixesha elifanelekileyo kunye nenqanaba lokuphendula eliphantsi, kunye nenqanaba lokugqibela lesamente emva kokuqina. ingxaki yokuqhekeka.
4. Ukugcinwa kwamanzi:
Isiphumo sesiqu somxholo we-selselose ekutsaleni ekugcinweni kwamanzi safundwa. Kufunyenwe ukuba ukonyuka komxholo we-Ilet Sether, inqanaba lokugcina amanzi onyuswa, kwaye xa umxholo we-talsulose e-Ether i-Ether inkulu kakhulu i-0.6%, iqondo lokugcina amanzi lihlala lizinzile. Nangona kunjalo, xa uthelekisa iintlobo ezintathu zeSeluplose e-Telupms Ubudlelwane phakathi kwenqanaba lokugcina amanzi yile: mc-5.
