Liseleseli sebelisoa ka ho eketsehileng linthong tse entsoeng ka samente, haholo-holo liretseng tse omeletseng, ka lebaka la ho boloka metsi a tsona hantle le liphello tse teteaneng.Ka hona, thepa le mokhoa oa ho theha oacellulose ether lisebelisoa tse fetotsoeng tsa samente le tšebelisano lipakeng tsacellulose ether 'me seretse sa samente butle-butle se fetohile sepheo sa tlhokomelo mafapheng a thepa ea mohaho le boenjiniere lilemong tsa morao tjena.Liphetho tse ngata tsa lipatlisiso li fihletsoe.Ho kopanya tsoelopele ea lipatlisiso lapeng le kantle ho naha, ho ntse ho na le mathata a latelang lipatlisisong le ts'ebelisong eacellulose ether lisebelisoa tse fetotsoeng tse thehiloeng ho samente:
1.Ho na le mefuta e mengata eali-cellulose.Leha ho le joaloli-cellulose e sebelisoang ka thepa e thehiloeng ho samente e arotsoe ka mefuta e mengata e kang HEC, HEMC le HPMC ka lebaka la tekanyo ea tsona ea ho fetola.Mofuta o tšoanang oali-celluloseli na le liphapang tse ngata sebopehong sa limolek'hule, boima ba limolek'hule, tekanyo ea ho nkela sebaka kapa litaba tse ling.Hajoale, lipatlisiso tse ngata lapeng le kantle ho naha li shebana le e le 'ngoe kapa tse' maloali-cellulose.Khetho eacellulose ether e lekanyelitsoe mafapheng a fapaneng a ts'ebeliso ea bona.Litšobotsi tsa sebopeho sa limolek'hule tsali-cellulose ha li bontšoe, 'me boemeli ba tsona ha bo emele.Qeto ke sephetho se ke keng sa qojoa sa "phatlalatso e itseng", 'me ho na le likhanyetsano le likhohlano lipakeng tsa liphetho tsa liteko.Ka hona, hoa hlokahala ho ithuta ka mokhoa o hlophisehileng likarolo le thepa ea sebopeho le mekhoa ea mefuta e fapaneng eacellulose ether lisebelisoa tsa gelling tse fetotsoeng.
2.Lingoliloeng tse teng li ithutile phello eali-cellulose ka thepa e fapaneng ea thepa ea samente, 'me a etsa tlhahlobo e itseng ea mokhoa oa sebopeho sa eona, empa a hloleha ho fumana kamano lipakeng tsa sebopeho sa limolek'hule.li-cellulose le thepa ea seretse sa samente se fetotsoeng.kamehla, 'me ho na le phapang e hlakileng mekhoeng ea bona.Har'acellulose ether-lisebelisoa tse entsoeng ka samente tse fetotsoeng, ho na le lithuto tse fokolang mabapi le lisebelisoa tse nang le meaho e fapaneng ea limolek'hule, tse ke keng tsa hlalosa hantle mokhoa oa sebopeho sa thepa e fapaneng.cellulose ether-lisebelisoa tse fetotsoeng tsa samente..Le hoja lingoliloeng tse ling li ile tsa fumana seoli-cellulose ka mekhoa e fapaneng ea limolek'hule e na le liphello tse fapaneng ho hydration ea samente, mabaka a ka sehloohong ha a e-s'o hlalosoe ka ho eketsehileng.
3.Mokhoa oa ts'usumetso eacellulose ether ka samente hydration kinetics e sa ntse e tla ithutoa ho ea pele.Hajoale, mabapi le mokhoa o liehang oa hydration oacellulose ether, le hoja adsorption e nkoa e le sesosa sa sebele sa ho lieha ho phalla ha metsicellulose ether, ho fumanoa hore matla a adsorption a matla pakeng tsa lihlahisoa tsa hydration lecellulose ether, ha samente e lieha ho fana ka metsi.The adsorption mechanism betweenli-cellulose le lihlahisoa tsa samente hydration, hammoho le mabaka a tse fapaneng adsorption bokgoni ba fapanengli-cellulose le lihlahisoa tsa samente tsa hydration, ha li so ithutoe ho ea pele.
4.Lingoliloeng tse teng li bontša horeli-cellulose e ka ama haholo sebopeho sa pore ea thepa e thehiloeng ho samente.Liselese li boetse li lumeloa hore li sebetsa ka holim'a metsi 'me li na le phello ea moea ho li-slurries tse ncha tsa samente, kahoo li eketsa porosity ea li-slurries tse thata tsa samente.Leha ho le joalo, tšusumetso eali-cellulose ka mokhoa o tloaelehileng le oa ho thehoa ha samente slurry pore size distribution ha ho buuoe ka seoelo.
5. Thepa ea mali ke karolo ea bohlokoa ea tšebeliso eali-cellulose linthong tse entsoeng ka samente.Ka bomalimabe, ho na le liphuputso tse fokolang mabapi le thepa ea rheological eacellulose ether seretse sa samente se fetotsoeng lapeng le kantle ho naha.
