I-SelerUlose Ether yi-polymer ye-Syntmer eyenziwe kwi-selupese yendalo ngokuguqula iikhemikhali. I-SelerUlose Ether yindawo yokukhutshwa kwendalo. Ukuveliswa kwe-ether yeselselose yahlukile kwi-polymers yokwenziwa. Eyona nto iphambili kuyo esisiseko yi-sellulose, i-polymer yendalo. Ngenxa yobunye besakhiwo sendalo seselfowuni, i-selsulose ngokwayo ayinakwazi ukusabela ngeearhente zokhenketho. Nangona kunjalo, emva konyango iarhente yokudumba, iimbophelelo ze-hydrogen eqinileyo phakathi kweemolekyuli kunye namakhonkco atshatyalaliswayo, kwaye ukukhutshwa kweqela le-hydroxyl iba yi-alkali. Fumana i-sell sether.
Iipropathi ze-Selesese Hailes zixhomekeke kuhlobo, inani kunye nokusasazwa kwezinto ezizimeleyo. Ukwahlula-hlula i-Ether Selesese i-Ether ikwahlelwa ngokohlobo lwe-ether, isidanga sokuthengiswa, ukonakala kunye neepropathi ezinxulumene noko. Ngokutsho kohlobo lokuthathela izinto kwi-molecular thein, inokwahlulwa ibe yi-monotere kunye ne-ether exubeneyo. I-MC ihlala isebenzisa i-monoether, kwaye i-HPMC ixutywe nether. I-methyl seluplose ether MC yimveliso emva kweQela le-hydroxyl kwicandelo le-Glucose ye-Gluolose ye-Floulose ifakwe ngendlela eyiyo. Yimveliso efunyenwe ngokufaka indawo yeqela le-hydroxyl kwiyunithi eneqela le-AFCHYy kunye nelinye icandelo ngeqela le-hydroxlypropy. Ifomula yesakhiwo i [c6h7o2 (oh) i-3-Mn (OCH2CH2) M [OCH2CH (O) i-Hydroxyl Sethy, ezi zezona zinto ziphambili zentengiso zisetyenziswa kakhulu kwaye zithengiswa emarikeni.
Ngokuphathelelene nokuluka, kunokwahlulwa kwi-Ionic kwaye ingenzi-i-ionic. I-ionic forwecle inyibiliki ye-ionic selsulose edityaniswe ikakhulu yochungechunge amabini eAlkyl I-Ionic CMC isetyenziswa ikakhulu kwizinto zokucoca ngokukuko, ukuprinta okubhaliweyo kunye nokudaya, ukutya kunye nokuhlolwa kweoyile. I-Ionic MC, i-HPMC, i-HMC, njl njl. Zisetyenziswa ikakhulu kwizixhobo zokwakha, i-Latex Coatings, iarhente yemihla ngemihla, i-stailing, i-stivering kunye nearhente yefilimu yefilimu.
Ukuchongwa komgangatho we-seluplose ether:
Iziphumo zomxholo we-APENGSYL kumgangatho: Ukugcinwa kwamanzi kunye nomsebenzi wokuthambisa
Umgangatho ophantsi wempembelelo ye-hydroxyeXyl / hydroxypropoxyl Umxholo: Ukuphakama komxholo, kungcono ukugcinwa kwamanzi.
Impembelelo ye-viscosity esemgangathweni: Ukuphakama kwe-polymerization, ukuphepha i-viscosity kunye nokugcinwa kwamanzi.
Impembelelo yoMgangatho wokuTywala: Ukuhlaziya ukusasazeka kunye nokuchithwa kodaka, ngokukhawuleza kwaye iyunifomu engaphezulu, kunye nokugcinwa kwamanzi okuhlala kungcono
Impembelelo esemgangathweni yokukhanya kokukhanya: Inqanaba eliphezulu le-polymerizazation, ngakumbi iyunifomu ye-polymerization, kunye nokungcola okuncinci
Impembelelo yobushushu be-Gel yobushushu
Impembelelo yomgangatho wamanzi: <5%, i-SeleyE i-Ether kulula ukuyifumana ukufuma, kufuneka itywinwe kwaye igcinwe
Impembelelo yomgangatho we-ASS
Ixabiso elisemgangathweni yeXP
