Izakhiwo ze-Physicochemical of Cellulose Afers

Izakhiwo ze-physicochemical of cellulose izithatheketha, ezisuselwa kuma-cellulose eziguqulwa ngezinqubo zamakhemikhali, ziyahlukahluka ngokuya ngezinto ezifana nohlobo oluthile lwe-cellulose ether, izinga lokufaka esikhundleni (DS), nezinye izici zesakhiwo. Nazi ezinye izakhiwo ze-physicochemical ezivame ukuhlotshaniswa nokuphatha izithasiselo ze-cellulose:

1. I-Solubity:

• I-Solubity yamanzi:I-Cellulose Aferszivame ukwethuka amanzi, zakha izixazululo ezicacile nezibonakalayo lapho zihlanganiswa namanzi. Izinga le-solubity lingathonywa ngohlobo oluthile lwe-cellulose ether kanye ne-DS yalo.

2. Isakhiwo samakhemikhali:

• I-Cellulose Teshers igcina ukwakheka okuyisisekelo kwe-cellulose, okubandakanya ukuphinda ama-glucose amayunithi axhumene nezibopho ze-β-1,4-glycosidic. Ukuguqulwa kwamakhemikhali kwethula amaqembu ahlukahlukene ahlukahlukene, njenge-hydroxyyethyl, hydroxypropyl, noma i-carboxymethyl, kuya ngohlobo lwe-cellulose ether.

3. Izinga lokufaka esikhundleni (DS):

• I-DS ikhombisa inani eliphakathi lamaqembu afakwa esikhundleni ngeyunithi ngayinye ye-Anhydroglucose eCellulose Chain. Ithonya kakhulu izakhiwo ze-cellulose izithatha, ezinjengamanzi e-solubity, ukuhlakanipha nokusebenza.

4. Isisindo samangqamuzana:

• Isisindo samangqamuzana se-cellulose afer kuyahlukahluka ngokuya ngenqubo yokukhiqiza kanye nesicelo osifunayo. Isisindo esiphakeme se-molecular cellulose izitha, ngokwesibonelo, singabonisa izakhiwo ezahlukahlukene ze-herological kanye ne-viscosity uma kuqhathaniswa nabalingani besisindo se-molecular.

5. I-Viscosity:

• I-Cellulose Tashers isebenza njengezikhulu ezisebenza ngempumelelo, futhi ukubonakala kwazo kuyindawo ebalulekile kwizicelo eziningi. I-viscosity ingathonywa yizinto ezifana nokuhlushwa, izinga lokushisa, kanye nesisindo se-molecular. Izinsimbi eziphakeme ze-molecular cellulose, izithambiso zivame ukufaka isandla ekubonakaleni okuphezulu.

6. Izakhiwo ze-Rheological:

• Ukuziphatha kwe-Rhelloological of Cellulose Afers kunquma izici zazo zokugeleza nezimo. Ithonywa yizinto ezifana nokuhlushwa, izinga lokugunda, kanye nokushisa. I-Cellulose Tathers iyaziwa ukukhombisa indlela yokuziphatha ye-Pseudoplastic, lapho ukubonakala kwehla khona ngezinga elikhulayo le-shear.

7. Ukwakheka kwe-gel:

• I-Cellulose Afers ethile inamandla okwenza ama-gels ngaphansi kwemibandela ethile, ifaka isandla kuhlelo lwayo njengabakhuthele kanye nokuzinza ngezindlela ezahlukahlukene.

8. Izakhiwo ezenziwe ngefilimu:

• Ezinye izithambiso ze-cellulose ekhombisa iFilm-ekwakha izakhiwo, ezakha amafilimu amancanyana, asobala ezindaweni eziphansi. Le mpahla isetshenziselwa ukugqoka, ukunamathela, kanye nezinye izinhlelo zokusebenza.

9. Ukugcinwa kwamanzi:

• I-Cellulose Tathers imvamisa inezakhiwo ezinhle kakhulu zokugcina amanzi, ibenze babalulekile ezintweni zokwakha, lapho basiza khona ukulawula izikhathi zokomisa futhi bathuthukise ukuzokwenza.

10. Ukuzwela okushisa:

11. Ukuqina kwamakhemikhali:

12. Ukuhlehlisa:

13. Ukuvumelana:

Ukuqonda lezi zindawo ze-physicochemical kubalulekile ukuze kuqondiswe izithasiselo ze-mourle Abakhiqizi bavame ukuhlinzeka ngemininingwane enemininingwane kanye nemihlahlandlela yokusetshenziswa kwemikhiqizo yabo ye-cellulose ether kuzicelo ezihlukile.
