Nyochaa nke nkesa nkesa na eyers cell

Na-enyocha nkesa nkesa naEversgbọala Cellugulna-agụnye otu esi amụ ihe na ebe hydroxyethyl, carroxythyl, a na-ekesa ndị ọzọ ndị ọzọ na polmer polymer. Ihe nkesa ndị dị mma na-emetụta akụrụngwa na arụmọrụ nke eyers mkpụrụ osisi, na-emetụta ihe ndị dị ka ngere, viscosity, na nlegharị anya. Ndị a bụ ụfọdụ usoro na echiche maka nrụpụta nrụpụta:

1. Sconlance nkọ (nmr) Streetcopy:
   • Thirdzọ: nmr StoreSroscopy bụ usoro dị ike maka ijigide usoro kemịkal nke etters. Ọ nwere ike ịnye ozi gbasara nkesa nke ndị nọchiri anya polymer yinye.
   • Nyochaa: Site na nyocha nomtụ NMR, mmadụ nwere ike ịchọpụta ụdị na ọnọdụ nke ndị nọchiri anya ya, yana ogo nke dochie anya (DS) na ọkwá dị na sellose backbone.
2. NKPERE (IR) Specreroscopy:
   • Formzọ: Enwere ike iji Stimproscopy, enwere ike iji Stimproscopy.
   • Nyocha: Band Abparption dị iche iche na IR Spormum nwere ike igosi ọnụnọ nke ndị nọ. Dịka ọmụmaatụ, ọnụnọ nke hydroxyethyl ma ọ bụ otu carroxyylyl nwere ike ịmata site na njiri mara ọnụ.
3. Ntinye aka (DS):
   • Forzọ: DS bụ usoro nke ọnụ ọgụgụ nke ebe a na-ejikarị otu akụkụ Anhydrogluse na eyers mkpụrụ osisi. A na-ekpebikarị ya na nyocha kemịkalụ.
   • Nyocha: Usoro kemịkalụ dị iche iche, dị ka akwụkwọ akụkọ ma ọ bụ chromatography, enwere ike iji ya chọpụta ihe ds. Vskpụrụ DS nwetara ozi na-enye ozi gbasara ọkwa dị iche iche mana enweghị ike ịkọwapụta nkesa.
4. Mgbasa Ozi Molecular:
   • Azọ: GEL Permeanion chromato (GPC) ma ọ bụ nha chromatography (set) iji chọpụta nkesa akwara nke eyers cellular.
   • Nyocha: nkesa molecula na-enye nghọta n'ime polymer yinye ogologo na otu ha ga-esi dị iche site na nkesa nkesa.
5. Hydrolysis na nyocha usoro:
   • Forzọ: na-achịkwa hydrolysis nke ethers cellulose sochiri chromatographic ma ọ bụ nyocha dị iche iche.
   • Nyocha: Site na ndị nnọchi anya a kapịrị ọnụ, ndị na-eme nchọpụta nwere ike inyocha iberibe na-ebute iji ghọta nkesa na ọnọdụ nke igwe cellulose.
6. Mass Stiattometry:
   • Forzọ: Mass dị ka Maldi-Tofti-Tof (Laser na-enyere aka na-enyere matring oge / ụgbọ elu) MS, nwere ike inye ozi zuru ezu gbasara ihe mejupụtara molecular.
   • Nyochaa: Mass dị iche iche nwere ike ikpughe nkesa nke polymer na ụdọ polymer n'otu n'otu, na-enye nghọta n'ime eyers cellususe nke eyers cellususe nke etters.
7. X-ray Crishstally:
   • Forzọ: x-ray kristal nwere ike ịnye ozi zuru ezu banyere ụzọ atọ-akụkụ ahụ nke ethers.
   • Nyochaa: Ọ nwere ike inye nghọta n'ime nhazi nke ndị nọ na mpaghara kristal nke eyers cellstalline.
8. Compatisite Mmezi:
   • Filzọ: Dyọmdị obi dị iche iche na usoro kọmputa nwere ike ịnye nghọta nke usoro mmụta na nkesa nke ndị.
   • Nyochaa: Site na ime ka omume nke eyers cellulose na ọkwa molecular, ndị ọrụ nyocha nwere ike nweta nghọta nke otu esi ekesasị ndị jigide ya ma na-emekọrịta ihe.

Nyochaa nkesa nkesa na usoro cellugul bụ ọrụ dị mgbagwoju anya nke na-emetụtakarị ngwakọta usoro nnwale na ụdị usoro. Nhọrọ nke usoro dabere na mmasị dị iche iche nke mmasị na ọkwa nke nkọwapụta achọrọ maka nyocha ahụ.
