I-Cellulose I-Teshers nendlela yokukhiqiza okufanayo

Ukukhiqizwa kweI-Cellulose AfersKubandakanya uchungechunge lokuguqulwa kwamakhemikhali ku-cellulose, okuholele ekutholeni okuhlukahlukene ngezakhiwo ezihlukile. Okulandelayo ukubuka konke okujwayelekile kwezindlela ezisetshenziselwa ukukhiqiza izipho lezinto ezilandelwayo:

1. Ukukhetha komthombo weselula:

• I-Cellulose Afers ingasuselwa emithonjeni ehlukahlukene efana ne-solip pulp, ama-cotton linter, noma ezinye izinto ezenzelwe izitshalo. Ukukhethwa komthombo weselula kungathinta izici zomkhiqizo wokugcina we-cellulose ether.

2. Ukuphamba:

• Umthombo we-cellulose uphupha ukuthi aphule imicu ibe yifomu elilawulwa ngokwengeziwe. Ukuphambuka kungatholakala ngoMeyili, amakhemikhali, noma inhlanganisela yazo zombili izindlela.

3. Ukuhlanza:

• I-cellulose ephepheni ifakwa ngaphansi kwezinqubo zokuhlanza ukususa ukungcola, i-lignin, nezinye izinto ezingezona ze-cellulosic. Ukuhlanzwa kubalulekile ekutholeni impahla esezingeni eliphakeme.

4. Ukwenza kusebenze kwe-cellulose:

• I-cellulose ehlanziwe icushiwe ngokulingisa kukhambi le-alkaline. Lesi sinyathelo sibalulekile ekwenzeni i-cellulose iphinde isebenze ngesikhathi sokuphendula okulandelayo kwetherade.

5. Ukuphendula okuthe xaxa:

• I-cellulose ecushiwe ithola ukusheshisa, lapho kwethulwa khona amaqembu e-ether emaqenjini ama-hydroxy ku-cellulose polymer chain. Ama-ejenti athe xaxa aphenyathi afaka i-ethylene oxide, i-propelly oxide, i-sodium chlororetate, i-methyl chloride, nabanye.
• Ukusabela kuvame ukwenziwa ngaphansi kwezimo ezilawulwayo zokushisa, ingcindezi, kanye no-pH ukufezekisa izinga elifunekayo lokufaka esikhundleni (DS) nokugwema ukusabela okuseceleni.

6. Ukungathathi hlangothi nokugeza:

• Ngemuva kokuphendula ukusheshisa, umkhiqizo uvame ukungathathi hlangothi ukuze ususe ama-reagents ngokweqile noma ngemikhiqizo. Izinyathelo zokugeza ezalandela zenziwa ukuqeda amakhemikhali asele nokungcola.

7. Ukomisa:

• I-cellulose ehlanziwe futhi ethe xaxa yomisiwe ukuthola umkhiqizo wokugcina we-cellulose ether ngofulawa noma nge-granular.

8. Ukulawulwa kwekhwalithi:

• Amasu ahlukahlukene wokuhlaziya, kufaka phakathi i-spectoscopy yenuzi yenuzi (NMR) Spectroscopy, i-Four-Transform infrared (ftir) spectroscopy, kanye ne-chromatography, zisetshenziselwa ukulawulwa kwekhwalithi. I-DS ibhekwe kakhulu ukuze iqinisekise ukuvumelana.

9. Ukuqanjwa kanye nesicelo:

• I-cellulose ether isenziwa ngamamaki ahlukene ukufeza izidingo ezithile zezicelo ezahlukahlukene. Abakwa-Cellulose abahlukene balungele izimboni ezihlukile, njengokwakha, amakhamishini, ukudla, ukumboza, nokuningi.

Kubalulekile ukuqaphela ukuthi izindlela nezimo ezithile zingahluka ngokuya ngomkhiqizo oyifunayo we-cellulose ether kanye nesicelo okuhlosiwe. Abakhiqizi bavame ukusebenzisa izinqubo zokuphathelene ukuze bakhiqize izithambiso ze-cellulose ezinezakhiwo ezithile ezenzelwe ukufeza izidingo zemboni ehlukahlukene.
