Ukuhlaziywa kokusatshalaliswa okuphezulu kwe-cellulose afers

Ukuhlaziya ukusatshalaliswa okubonakalayo ngaphakathiI-Cellulose AfersKubandakanya ukutadisha ukuthi i-hydroxyethyl, i-carboxymethyl, i-hydroxypropyl, noma ezinye izinto zisatshalaliswa ngase-cellulose polymer chain. Ukusatshalaliswa kwabathathwe esikhundleni kuthonya izakhiwo eziphelele kanye nokusebenza kwe-Cellulose Letter, kuthonya izici ezinjenge-solubity, ukubonakala kanye nokuvuselelwa kabusha. Nazi ezinye izindlela kanye nokucatshangelwa kokuhlaziya ukusatshalaliswa okuphezulu:

1. I-Nuclear Magnetic Resonance (NMR) Spectroscopy:
   • Indlela: I-NMR Spectroscopy iyindlela enamandla yokucacisa ukwakheka kwamakhemikhali ze-cellulose afes. Kunganikeza imininingwane mayelana nokusatshalaliswa kwabangeniswe esikhundleni esiseduze kwe-polymer chain.
   • Ukuhlaziywa: Ngokuhlaziya i-NMR Spectrum, umuntu angakhomba uhlobo nendawo yokufaka esikhundleni, kanye nezinga lokufaka esikhundleni (DS) ezikhundleni ezithile kwi-cellulose backbone.
2. I-infrared (ir) spectroscopy:
   • Indlela: I-IR Spectroscopy ingasetshenziselwa ukuhlaziya amaqembu asebenzayo akhona kuma-cellulose afes.
   • Ukuhlaziywa: Ama-band athile amunculiso ku-IR Spectrum angakhombisa ubukhona bokuthile. Isibonelo, ukuba khona kwe-hydroxyethyl noma ama-carboxymethyl angakhonjwa ngeziqongo zesimo.
3. Degree of inqume (DS) Ukuzimisela:
   • Indlela: I-DS yisilinganiso esilinganiselwe senombolo ephakathi yokufakazela iyunithi ngayinye ye-Anhydroglucose e-Cellulose Afers. Ngokuvamile kunqunywa ngokuhlaziywa kwamakhemikhali.
   • Ukuhlaziywa: Izindlela ezahlukahlukene zamakhemikhali, njengokuthathwa noma kwe-chromatography, kungaqashwa ukunquma ama-DS. Amanani we-DS atholakele ahlinzeka ngolwazi mayelana nezinga eliphelele lokufakwa esikhundleni kepha lingakwazi ukuhambisa imininingwane.
4. Ukusatshalaliswa kwesisindo molecular:
   • Indlela: I-Chromatography ye-Chromatography ye-GEL PERMOTEPORY (GPC) noma i-Chromatography yosayizi wokukhishwa (sec) ingasetshenziswa ukuthola ukusatshalaliswa kwesisindo kwama-molecular of cellulose.
   • Ukuhlaziywa: Ukusatshalaliswa kwesisindo amamolekyuli kunikeza ukuqonda kubude be-polymer chain nokuthi bahluka kanjani ngokusekelwe ekusatshalalisweni okuphezulu.
5. Amasu we-Hydrolysis kanye namasu wokuhlaziya:
   • Indlela: I-hydrolysis elawulwayo ye-cellulose tifers elandelwa ukuhlaziywa kwe-chromatomagraphic noma i-spectroscopic.
   • Ukuhlaziywa: Ngokukhetha ukubonwa okuthile kwe-hydrolyzing, abacwaningi bangahlaziya izingcezwana eziphumayo ukuze baqonde ukusatshalaliswa kanye nokubekwa esikhundleni kwabalinganiselwa ku-cellulose.
6. I-Mass Spectrometry:
   • Indlela: Amasu amakhulu okubuka ama-spectrometry, anjenge-maldi-tof (matrix-asizwa i-laser destorption / ionix-assign Time-of-time-of-fle fle fle fless), anganikeza imininingwane eningiliziwe mayelana nokwakheka kwamangqamuzana.
   • Ukuhlaziywa: I-spectrometry eningi ingaveza ukusatshalaliswa kokufakwa esikhundleni kwamaketanga ngamanye ama-polymer, okunikeza imininingwane ngama-heterogeneity of arlulose afebur.
7. I-X-ray Crystallography:
   • Indlela: I-X-Ray Crystallography inganikeza imininingwane eningiliziwe mayelana nokwakheka okunezinhlangothi ezintathu ze-cellulose afes.
   • Ukuhlaziywa: Kunganikeza imininingwane ekuhlelweni kokufakwa esikhundleni ezifundeni ze-crystalline ze-cellulose afes.
8. I-Computionaning Modeling:
   • Indlela: Ukufanisa ama-molecular dynamics kanye nemodeli yokuhlanganisa i-computational kunganikeza imininingwane yethiyori ekusatshalalisweni kwabangenisi.
   • Ukuhlaziywa: Ngokulingisa ukuziphatha kwezimali ze-cellulose ezingeni lamangqamuzana, abacwaningi bangathola ukuqonda ukuthi bahambisane kanjani futhi baxhumana kanjani.

Ukuhlaziya ukusatshalaliswa okuhlolisiwe e-Cellulose TETERS ngumsebenzi oyinkimbinkimbi ovame ukufaka inhlanganisela yamasu wokuhlola namamodeli wethiyori. Ukukhethwa kwendlela kuncike ekuhlolweni okuthize kwenzalo kanye nezinga lemininingwane edingekayo ukuze kuhlaziywe.
