Litlatsetso tsa Ether ke sehlopha sa polyumel ea likhechana tsa celluulo ea lik'hemik'hale ka lik'hemik'hale. Ka lebaka la sokoliana ea bona e ntle ea metsi, ho fetola phetoho ea liphetoho le kutloelo-bohloko maemong a kantle joalo ka mocheso le pōli, meriana le litlolo. Ts'ebetso ea taolo ea viscosion of cellulose e mong le e mong oa litšobotsi tsa eona a sebetsa ka bongata liprofinse tse ngata tsa indasteri le tsa letsatsi le letsatsi.
1. Tsamaiso le khethollo ea li-ethe tsa celluulose
Lits'ebetso tsa li-cellulose ether li lokisitsoe ho Celllulose ea Bofupu ka karabelo ea chelete. Cellulose ke compmer Pontmer e thehiloeng ke limoletsi tsa glucose e hokahantsoeng ke maqhama a β-1,4-glycsidic. Ts'ebetso ea ho hlophisoa ha li-silelose en e hlokang ho nka karolo ea hydroxy.
Ho latela hore na conbugent e nkiloeng, e tloaelehileng cell mothyl conmlloulose (HYDROXYL MethyMethyl MethyMeth Palo le boemo ba libaka tse nkang sebaka sa metsi ha li ame feela lial- tsa tsona ka kotloloho litšoantšiso tsa bona li theha bokhoni ba ho lemala.
2. Mechani ea sebopeho sa Viscosity
Matla a ho laoloa ke Babuelli ba li-celbolo la li-cellulose Ha liketsahalo tsa cellullo li qhibiliha metsing, lihlomo tsa polar li qhibiliha litlatsetso tsa metsi, tse eketsang thatlo ea lisele tsa cellulose, 'me tsa eketsa pherekano ea tharollo.
Boholo ba Viscosity bo amana haufi-ufi le boima ba limolek'hule, mofuta o nkiloeng, tekanyo ea sebaka (dp) ea ethe ea selefounu. Ka kakaretso, the e kholo ea limolek'hule ea e-ntloana ea celluulose le ketane ea molek'hule, pono ea tharollo. Ka nako e ts'oanang, sebaka se fapaneng se ama hydrophlicamy ea limolek'hule tsa limolek'hule, ka hona a ama allocules, ka hona a ama allocules, ka hona a ama allocules, ka hona a ama allocules, ka hona a ama allocity le pono ea tsona ka metsing. Mohlala, HPMC e na le botsitso ba metsi le botsitso ka lebaka la hydroxypropyl le methyl tse ling tsa methyl. Leha ho le joalo, cmc e na le pono e phahameng hobane e hlahisa lihlopha tse ngata tsa carboxyl tse qotsitsoeng ka thata ka lebaka la limolek'hule tsa metsi tse thata.
3. Phello ea mabaka a kantle ho Viscosity
Tsepe ea Elese ea Cellulose Ether e ipapisitse le sebopeho sa eona, empa hape le ho limong tsa tikoloho, ho kenyeletsoa mocheso, PH.
3.1 Mocheso
Mocheso ke karolo ea bohlokoa e amang pono ea pono ea Cellulose Ether. Ka kakaretso, Viscosity ea tharollo ea cellulose e fokotseha ho fokotseha ka mocheso o ntseng o eketseha. Sena ke hobane mocheso o ntseng o eketseha ho potlakisa ho sisinyeha ha pelo, ho senya likamano tsa limolek'hule ka metsing, ka ho etsa joalo tse fokotsang pono. Leha ho le joalo, ethe e 'ngoe e' ngoe e 'ngoe ea cellulose
3.2 boleng ba PH
Boleng ba PH le bona bo na le phello e bohlokoa ho infcosity ea cellulose ether. Bakeng sa li-ethe tsa celsiulos Bophene ba PH, sehlopha sa carboyl se imeloa haholo, e le hore ho be le lehloeo le matla la motlakase, ho etsa hore ho be bonolo ho limolek'hule ho bile bonolo ho li bala. Ha a le ka boleng ba pH, sehlopha sa carboyl ha se utloisise hantle, ho itlotsa ka motlakase ho fokotsehile, li-curls tsa molek'hule, 'me pono e fokotseha.
3.3 ion shesiso
Matla a ho tsepamisa maikutlo a Ion ho bona hore na ke lintho tsa silelose e leng ho totobetseng haholo. Cellulose Moud Ha ion khatello ea maikutlo ka tharollo e ntse e eketseha ka matlalo a elektrociatic pakeng tsa cellules, ka ho etsa joalo a fokotsa pono ea tharollo. Haholo-holo tikolohong e phahameng ea letsoai, vicootyity ea CMC e tla fokotsa haholo, e leng bohlokoa bo boholo bakeng sa moralo oa kopo.
4. Taolo ea liketsahalo ho masimong a kopo
Cellulose Ether o sebelisoa haholo masimong a mangata ka lebaka la ts'ebetso ea eona ea liphetoho tse ntle tsa Viscosity.
4.1 Lisebelisoa tsa Kaho
Sebakeng sa ho haha, Ether (joalo ka HPMC) Hangata phofo ea seretse se kopaneng le lihlahisoa tse ling tsa ho ameha nakong ea ho aha. Ka nako e ts'oanang, e ka senya chelete ea metsi, e ntlafatsa ho bolokoa ka metsi, 'me ka hona ho ntlafatsa matla le ho phehella sehlahisoa sa ho qetela.
4.2 Likooa le Inks
E-'-'-'-'li-'-'-'-'-'-'-'mōtoana ba selefouso le ba tsitsiseng litsebi tsa bosholu ba metsi le liseke. Ka ho fetola pono, ba netefatsa maemo le ho tšoarela ha ho koaloa nakong ea ho haha. Ntle le moo, e ka ntlafatsa le ho khaola ho koaheloang khang, ho fokotsa ho tsuba, le ho haha junifomo e joalo.
4.3 Meriana le lijo
Masimong a meriana le lijo, e-nply ethel (e kang hpmc, cmc) hangata e sebelisoa e le li-emuckered, emululizers kapa basetsi. Mohlala, HPMC, joalo ka lingoliloeng tse koahelang litafole, li ka fihlela phello e lokiselitsoeng ea lithethefatsi ka ho laola sekhahla sa disforation. Ka lijo, CMC e sebelisoa ho eketsa viscosion, ntlafatsa tatso ea lijo, le ho phela bophelo ba lijo.
Li-cosmetics tsa 4.4
Ts'ebeliso ea ethe ea bobuelm ea cellulose e tsoang ho li-cosmetics e tsepamisitsoe haholo limphong tse kang li-emulsions, gels le maske ea sefahleho le sefahleho. Ka ho fetola pono, e leng Chlyulose e-cellengse e ka fa sehlahisoa le mokhoa o nepahetseng oa sehlahisoa, 'me o thehe filimi e mengobo letlalong ho eketsa khothatso nakong ea ts'ebeliso.
Lits'ireletso tsa Ether tsa Ether li khona ho laola pono ea tharollo ka sebopeho sa bona se ikhethang sa sebopeho sa bona le ho arabela tikolohong ea kantle. Sena se lebisitse ho sebelisa lits'ebeletso tsa tsona tse ngata masimong a mangata joalo ka ho aha, meriana, lijo le litlolo. Ka nts'etsopele e tsoelang pele ea saense le theknoloji ea lisele e leng celluloulo e tla hola ho fana ka tharollo ea lihlahisoa tsa taolo ea liketsahalo tse laolang.
