Mekhoa e Meng ea ho qhala Cellulose Ether?

Ho kheloha li-ethe tsa celluulose e ka ba mohato oa bohloka indasteri, lijo, masela le kaho.ENDE ENSEe sebelisoa haholo ka lebaka la thepa ea bona e kang ho holisa, ho tlama, ho theha lifilimi le ho tsikitlanya motlakase. Leha ho le joalo, pherekano ea bona ka solvelin e ngata e ka baka mathata. Ho hlahisitsoe mekhoa e mengata ho hlakola ena e 'ntlhommetse hang ka katleho.

Li-solvents tsa khale:

Ho na le AlcalArphi. Leha ho le joalo, ba kanna ba se be bo loketseng mefuta eohle ea li-cellulos tsa bo-Celluloses mme ba ka hloka lithemparetjha tse phahameng.
Ether-cheke ea mahe a linotsi: Motsoako oa Dithyl Ether le Bothanol kapa Methanol hangata li sebelisetsoa ho qhala e-scolulose. Li-solvent tsena li fana ka tharollo e ntle 'me li sebelisoa hangata maemong a laboratoring.
Ketelo: Ketelo ea Acestone le Methyl Ethyl Ketone (Mek) e ka qhibilihisa mefuta e itseng ea e-ba cellulose. Acestone, ka ho khetheha, e sebelisoa hohle ka lebaka la litšenyehelo tsa eona tse tlase le katleho.
Ester: esters e kang ECEYL ACETED le Busyl Acetate e ka senya bo-'-e-elwana ba linyeoe ka katleho. Leha ho le joalo, ba kanna ba hloka ho futhumatsa hore ba fihle ho felisoa ka botlalo.

Tharollo ea Aquanous:

Tharollo ea Alkaline: Ba-Ether e 'nang le Cellulose ba ka felisoa ka tharollo ea alkaline ba joalo ka sodium hydroxide (naoh) kapa potasiah hydroxide (Koh). Tharollo ena hydrolyze e hlakisa letsoai la tšepe ea Alkali, e qhibilihang.
Tharollo ea Ammonia
Hydroxyalkyl ea hydroxxyal. Tharollo ea Urea kapa hydroxylpropityl

Maraba a ionic:

Li-talu tsa ionic li na le letsoai le lengata ka har'a lithemparetjha ka lithemparetjha tse tlase, hangata ka tlase ho 100 ° C. Mefuta e meng ea li-iiosi e fumanoe e hlasimolohile ka tšohanyetso ntle le tlhoko ea maemo a hlabang. Ba fana ka melemo e kang ea khethollo e tlase, ho tsilatsila ho phahama le ho hlolla hoa eketseha.

Litsamaiso tsa Soluvent tse kopaneng:

Ho kopanya li-solvetts tse fapaneng ka linako tse ling ho ka ntlafatsa scoubility ethei ea cellulose. Mohlala, motsoako oa metsi o nang le co-solvent sulfoxide (DMSO) kapa N-Methyl-2-Pyrrolidone (NPM) e ka ntlafatsa thepa ea dissol.
Hangata paramente ea Hansen ea lifofane e lula e hiriloe ho soma mekhoa e thata ea ho soma banters ea qhobosheane ea li-solven le litšebelisano tsa bona.

Mekhoa ea 'mele:

Ho kuta maikutlo: Ho kopanya ho phahameng kapa ho rapela ho ka u thusa ho hasanya li-kintrict tsa dissolotion.
Taolo ea mocheso: Boitšoaro bo phahameng hangata bo ka ntlafatsa ea bo-'mè ba khetlong ka thata, empa tlhokomelo eo re lokelang ho e nka ho qoba litšila tsa polymer.

Phetiso ea lik'hemik'hale:

Maemong a mang, ho inyenyefatso ea lik'hemik'hale ho ka ntlafatsa thepa ea tsona ea soko. Ka mohlala, ho hlahisa lihlopha tsa hydrophobic kapa ho eketsa tekanyo ea bolelele e ka etsa hore e-ba-e-so qhibilihe haholo ka li-solric solvent.

Tharollo ea MICLAR:

Li-surfactant li ka etsa li-micelles ka tharollo, e ka amohelangENDE ENSE. Ka ho fetola maemo a khatello ea potoloho le tharollo, a ka khona ho qhibiliha seo-cellengse o-khabane ka katleho.
Qetellong, khetho ea mokhoa oa ho soma bo-mme-'ng e itšetlehileng ka eona e kang mofuta oa mofuta oa cellulose, ea neng a lakatsa, tikoloho le kopo e reriloeng. Mokhoa o mong le o mong o na le menyetla le mefokolo ea eona le mefokolo ea eona e tsoela pele ho hlahloba mabenkele a macha a ho ntlafatsa phetisetso ea ho felisoa ha liketsahalo tsa cellulos ka li-solvents tse fapaneng.
