Isesengura ryikwirakwizwa ryibintu muri Cellulose Ethers

Gusesengura ikwirakwizwa ryibisimburwa muriselile ethersbikubiyemo kwiga uburyo na hydroxyethyl, carboxymethyl, hydroxypropyl, cyangwa ibindi bisimburana bigabanywa kumurongo wa selile ya polymer. Ikwirakwizwa ryinsimburangingo rigira ingaruka kumiterere rusange nimikorere ya selile ya selile, bigira ingaruka nkibisubizo, ibishishwa, hamwe nubushake. Hano hari uburyo hamwe nibitekerezo byo gusesengura ikwirakwizwa:

1. Nuclear Magnetic Resonance (NMR) Spectroscopy:
   • Uburyo: NMR spectroscopy nubuhanga bukomeye bwo gusobanura imiterere yimiti ya selile. Irashobora gutanga amakuru ajyanye no gukwirakwiza insimburangingo kumurongo wa polymer.
   • Isesengura: Ukoresheje isesengura rya NMR, umuntu arashobora kumenya ubwoko n’aho biherereye, kimwe n’urwego rwo gusimbuza (DS) ku myanya yihariye ku mugongo wa selile.
2. Infrared (IR) Spectroscopy:
   • Uburyo: IR spectroscopy irashobora gukoreshwa mugusesengura amatsinda akora muri selile ya selile.
   • Isesengura: Imirongo yihariye yo kwinjiza muri IR igaragaramo irashobora kwerekana ko hari insimburangingo. Kurugero, kuba hydroxyethyl cyangwa carboxymethyl matsinda bishobora kumenyekana nimpinga ziranga.
3. Impamyabumenyi yo gusimbuza (DS) Icyemezo:
   • Uburyo: DS ni igipimo cyinshi cyumubare mpuzandengo wibisimburanya kuri anhydroglucose muri selile ya selile. Bikunze kugenwa hifashishijwe isesengura ryimiti.
   • Isesengura: Uburyo butandukanye bwimiti, nka titre cyangwa chromatografiya, birashobora gukoreshwa kugirango umenye DS. Indangagaciro DS yabonye itanga amakuru kubyerekeranye nurwego rusange rwo gusimburwa ariko ntishobora gusobanura neza kugabana.
4. Ikwirakwizwa ryibiro bya molekulari:
   • Uburyo: Gel permeation chromatografiya (GPC) cyangwa ubunini-bwo gutandukanya chromatografiya (SEC) irashobora gukoreshwa kugirango hamenyekane uburemere bwa molekile ikwirakwizwa rya selile.
   • Isesengura: Ikwirakwizwa ryibiro bya molekuline ritanga ubushishozi muburebure bwa polymer nuburyo bishobora gutandukana ukurikije igabanywa ryimbaraga.
5. Hydrolysis hamwe nubuhanga bwo gusesengura:
   • Uburyo: Igenzurwa na hydrolysis ya selile ya selile ikurikirwa na chromatografique cyangwa isesengura rya spekitroscopique.
   • Isesengura: Muguhitamo hydrolyzing insimburangingo yihariye, abashakashatsi barashobora gusesengura ibice byavuyemo kugirango basobanukirwe ikwirakwizwa n imyanya yabasimbuye kumurongo wa selile.
6. Mass Spectrometry:
   • Uburyo: Ubuhanga bwa sprometrometrike, nka MALDI-TOF (Matrix-Ifashwa na Laser Desorption / Ionisation Igihe-cy'Indege) MS, irashobora gutanga amakuru arambuye kubyerekeye molekile.
   • Isesengura: Mass spectrometrie irashobora kwerekana ikwirakwizwa ryinsimburangingo kumurongo wa polymer kugiti cye, bigatanga ubushishozi muburyo butandukanye bwa selile ya selile.
7. X-ray Crystallography:
   • Uburyo: X-ray kristallografiya irashobora gutanga amakuru arambuye kubyerekeye imiterere-yimiterere itatu ya selile.
   • Isesengura: Irashobora gutanga ubushishozi muburyo bwo gutondekanya insimburangingo mu turere twa kristalline ya selile.
8. Uburyo bwo Kubara:
   • Uburyo: Imikorere ya molekulari igereranya no kubara irashobora gutanga ubushishozi muburyo bwo gukwirakwiza insimburangingo.
   • Isesengura: Mu kwigana imyitwarire ya selile ya selile kurwego rwa molekile, abashakashatsi barashobora gusobanukirwa nuburyo insimburangingo zitangwa kandi zikorana.

Gusesengura gukwirakwiza insimburangingo muri selile ya selile ni umurimo utoroshye akenshi urimo guhuza tekinike yubushakashatsi hamwe nicyitegererezo. Guhitamo uburyo biterwa ninsimburangingo yihariye yinyungu nurwego rwibisobanuro bisabwa kugirango isesengura.
