Ukulungiswa kwe-cellulose afes

Ukulungiswa kweI-Cellulose AfersKubandakanya ukulungisa amakhemikhali ukuguqula i-polymer cellulose yemvelo ngokuphendula okuthe xaxa. Le nqubo yethula amaqembu e-ether emaqenjini ama-hydroxyl we-cellulose polymer chain, okuholela ekwakhekeni kwe-cellulose aferties enezakhiwo ezihlukile. I-cellulose tallulose evame kakhulu ifaka i-hydroxypropyllylkyll methylcellulose (HPMC), i-carboxymethyl cellulose (CMC), i-hydroxyyethyl cellulose (i-methylylyl cellulose (i-methyl cellulose (i-metlulose (MC). Nasi umbono jikelele wenqubo yokulungiselela:

1. I-cellulose Sourcing:

• Inqubo iqala ngokuthola i-cellulose ye-sourcing, okuvame ukuthathwa kusuka ku-soni pulp noma ukotini. Ukukhethwa komthombo weselula kungathonya izakhiwo zomkhiqizo wokugcina we-cellulose ether.

2. Ukuphamba:

• I-cellulose ifakwa ezinqubweni zokuphamba ukudiliza imicu ibe yifomu elilawulwa ngokwengeziwe. Lokhu kungafaka izindlela zokwelapha noma zamakhemikhali.

3. Ukuhlanza:

• I-cellulose ihlanjululwa ukususa ukungcola, i-lignin, nezinye izinto ezingezona ze-cellulosic. Lesi sinyathelo sokuhlanza sibalulekile ekutholeni impahla esezingeni eliphakeme.

4. Ukuphendula okuthe xaxa:

• I-cellulose ehlanziwe ithola ukusheshisa, lapho kwethulwa khona amaqembu e-ether emaqenjini ama-hydroxy ku-cellulose polymer chain. Ukukhethwa komenzeli we-ejenti kanye nezimo zokuphendula kuya ngomkhiqizo oyifunayo we-cellulose ether.
• Ama-ejenti athe xaxa aphenyathi afaka i-ethylene oxide, i-propelly oxide, i-sodium chlororetate, i-methyl chloride, nabanye.

5. Ukulawulwa kwamapharamitha wokuphendula:

• Ukusabela kokusheshisa kulawulwa ngokucophelela ngokuya ngamazinga okushisa, ingcindezi, kanye no-pH ukufeza izinga olufunayo lokufaka esikhundleni (DS) futhi ugweme ukusabela okuseceleni.
• Izimo ze-Alkaline zivame ukuqashwa, futhi i-PH yengxube yokusabela ibhekwe kakhulu.

6. Ukungathathi hlangothi nokugeza:

• Ngemuva kokuphendula ukusheshisa, umkhiqizo uvame ukungathathi hlangothi ukuze ususe ama-reagents ngokweqile noma ngemikhiqizo. Lesi sinyathelo silandelwa ngokugeza ngokuphelele 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 aqashwa ngokulawulwa kwekhwalithi, kufaka phakathi i-pucletic magnetic resonance (NMR) Spectroscopy, i-Four-Transform infrared (ftir) spectroscopy, ne-chromatography.
• Izinga lokufaka esikhundleni (DS) liyipharamitha ebucayi ebhekwe ngesikhathi sokukhiqiza ukuze kuqinisekiswe ukuvumelana.

9. Ukuqanjwa kanye nokupakisha:

• I-cellulose ether isenziwa ngamamaki ahlukene ukufeza izidingo ezithile zezicelo ezahlukahlukene. Imikhiqizo yokugcina ihlanganiswe ukusatshalaliswa.

Ukulungiswa kwe-Cellulose TETERS kuyinqubo eyinkimbinkimbi yamakhemikhali edinga ukulawula ngokucophelela kwezimo zokuphendula ukuze kufinyelelwe kwizakhiwo ezifiselekayo. Ukuguquguquka kwezimali ze-cellulose zivumela ukusetshenziswa kwazo ezinhlotsheni eziningi zezicelo kuyo yonke imboni, kufaka phakathi amakhemikhali, ukudla, ukwakhiwa, ukumboza, nokuningi.
