Uyini umehluko phakathi kwe-starch ether ne-cellulose ether?

I-ether yesitashi ne-cellulose ether yizo zombili izinhlobo zokuphuma kwe-ether ezisetshenziswa ezimbonini ezihlukahlukene, ikakhulukazi ekwakheni nasekuhlanganiseni. Nakuba zabelana ngokufana okuthile mayelana nokuba ama-polymers ancibilika emanzini anezakhiwo ezijiyayo neziqinisayo, kunomehluko oyisisekelo phakathi kwawo, ikakhulukazi emthonjeni wawo kanye nesakhiwo samakhemikhali.

Isitashi i-Ether:

1. Umthombo:
- Imvelaphi Yemvelo: Isitashi ether sisuselwa kusitashi, okuyi-carbohydrate etholakala ezitshalweni. Isitashi sivame ukukhishwa ezitshalweni ezifana nommbila, amazambane, noma umdumbula.

2. Isakhiwo Samakhemikhali:
- I-Polymer Ukwakheka: Isitashi yi-polysaccharide eyakhiwe amayunithi e-glucose axhunywe amabhondi e-glycosidic. Ama-ether esitashi aphuma kokunye okuguquliwe kusiitashi, lapho amaqembu e-hydroxyl ku-molecule yesitashi athathelwa indawo ngamaqembu e-ether.

3. Izinhlelo zokusebenza:
- Imboni Yokwakha: Ama-ether esitashi avame ukusetshenziswa embonini yezokwakha njengezithasiselo emikhiqizweni esekwe ku-gypsum, osimende, nezinto ezisekelwe kusimende. Banomthelela ekwenzeni ngcono ukusebenza, ukugcinwa kwamanzi, nokunamathela.

4. Izinhlobo Ezivamile:
- I-Hydroxyethyl Isitashi (HES): Olunye uhlobo oluvamile lwe-starch ether isitashi se-hydroxyethyl, lapho amaqembu e-hydroxyethyl ethulwa khona ukuze kulungiswe isakhiwo sesitashi.

I-Cellulose Ether:

1. Umthombo:
- Umsuka Wemvelo: I-Cellulose ether itholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli zezitshalo. Iyingxenye enkulu yezindonga zamaseli ezitshalo futhi ikhishwa emithonjeni efana ne-wood pulp noma ukotini.

2. Isakhiwo Samakhemikhali:
- I-Polymer Composition: I-Cellulose iyi-polymer eqondile ehlanganisa amayunithi e-glucose axhunywe ngamabhondi e-β-1,4-glycosidic. Ama-cellulose ether aphuma ku-cellulose, lapho amaqembu e-hydroxyl ku-molecule ye-cellulose eshintshwa ngamaqembu e-ether.

3. Izinhlelo zokusebenza:
- Imboni Yezokwakha: Ama-cellulose ether athola ukusetshenziswa kabanzi embonini yezokwakha, afana ne-starch ethers. Asetshenziswa emikhiqizweni esekwe kusimende, izinto zokunamathisela amathayela, kanye nodaka ukuze kuthuthukiswe ukugcinwa kwamanzi, ukusebenza kahle, nokunamathela.

4. Izinhlobo Ezivamile:
- I-Hydroxyethyl Cellulose (HEC): Olunye uhlobo oluvamile lwe-cellulose ether i-hydroxyethyl cellulose, lapho amaqembu e-hydroxyethyl ethulwa khona ukuze kulungiswe isakhiwo se-cellulose.
- I-Methyl Cellulose (MC): Olunye uhlobo oluvamile i-methyl cellulose, lapho amaqembu e-methyl ethulwa khona.

Umehluko Obalulekile:

1. Umthombo:
- Isitashi i-ether sisuselwa kusitashi, icarbohydrate etholakala ezitshalweni.
- I-Cellulose ether itholakala ku-cellulose, ingxenye enkulu yezindonga zamaseli ezitshalo.

2. Isakhiwo Samakhemikhali:
- I-polymer eyisisekelo ye-starch ether isitashi, i-polysaccharide eyakhiwe amayunithi e-glucose.
- I-polymer eyisisekelo ye-cellulose ether yi-cellulose, i-polymer eqondile eyakhiwe amayunithi e-glucose.

3. Izinhlelo zokusebenza:
- Zombili izinhlobo zama-ether zisetshenziswa embonini yezokwakha, kodwa izinhlelo zokusebenza ezithile kanye nokwakheka kungase kuhluke.

4. Izinhlobo Ezivamile:
- I-Hydroxyethyl isitashi (HES) ne-hydroxyethyl cellulose (HEC) ziyizibonelo zalezi ziphuma ether.

kuyilapho isitashi ether kanye ne-cellulose ether kokubili kungama-polymers ancibilika emanzini asetshenziswa njengezithasiselo ezisetshenziswa ezihlukahlukene, umthombo wawo, i-polymer eyisisekelo, kanye nezakhiwo zamakhemikhali ezithile ziyahluka. Lo mehluko ungaba nomthelela ekusebenzeni kwawo ekwakhiweni nasekusetshenzisweni okuthile.
