Uyini umehluko phakathi kwe-CMC (carboxyboxylyellulose) kanye ne-stack ether?

1. Ukwakheka nokwakheka:

CMC (carboxboxyylcellulose):

I-CMC iyisisulu se-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo.
Ama-molecule we-cellulose abhekana nenqubo yokuguqulwa kwamakhemikhali ebizwa nge-carboxmetylation, lapho amaqembu e-carboxymethyl (-CH2-COOH) angeniswa khona emhlane we-cellulose.
Izinga lokufakwa esikhundleni (DS) limelela inani lamaqembu e-carboxymethyl ngamunye uphiko lwe-glucose ku-cellulose chain.

Isitashi:

Isitashi i-carbohydrate ehlanganiswe ama-glucose amayunithi axhumeke ndawonye ngama-α-1,4-glycosidic bond.
Kuyinto polysaccharide lelo molekyule oyinhloko yokugcina amandla ezitshalweni.
Isitashi senziwe ngezinto ezimbili eziyinhloko: ama-amylose (amaketanga aqondile ama-glucose amayunithi) kanye ne-amylopectin (amaketanga ahlanganisiwe).

2. Umthombo:

Sodium carboxymethyl cellulose:

I-CMC ivame ukuthathwa kwimithombo yezitshalo ecebile enezindawo ezinjenge-solip pulp, ukotini, noma ezinye izitshalo ze-fibrous.
Inqubo ye-carboxymetylation iguqula iselula ibe amakhompiyutha angenamanzi ancibilikayo futhi ahlukahlukene.

Isitashi:

Isitashi sitholakala ngamanani amakhulu ezitshalweni ezahlukahlukene, kufaka phakathi okusanhlamvu (isib. Ummbila, ukolweni, ilayisi) kanye nezilimo eziyizigaxa (isib., Amazambane).
Inqubo yokukhishwa ifaka ukwephula izindonga zeseli ukudedela ama-granules wesitashi.

3. I-Solubity:

Sodium carboxymethyl cellulose:

I-CMC incane kakhulu ngenxa yokwethulwa kwamaqembu e-carboxymethyl, enikeza i-hydrophicity ku-molecule.
Yakha izixazululo ezicacile, ezi-viscous emanzini futhi ilungele izinhlelo ezahlukahlukene zezinsizakusebenza ezifana nokudla, amakhamishini kanye nezimonyo.

Isitashi:

Isitashi ngokuvamile singenakufakwa emanzini abandayo.
Kodwa-ke, ukufudumeza isitashi emanzini kubangela ukuvuvukala futhi ekugcineni kwakhiwe, kwakha ukumiswa kwe-colloidal.

Izakhiwo ze-4.Rhelogical:

Sodium carboxymethyl cellulose:

I-CMC ibonisa indlela yokuziphatha ye-Pseudoplastic, okusho ukuthi i-visa yayo yehla nge-shear stress.
Le mpahla ibalulekile ekusetshenzisweni kwezicelo lapho ukulawulwa khona kwe-viscosity kubaluleke kakhulu, njengokuqanjwa kwamapende, ukunamathela kanye nemikhiqizo yokudla.

Isitashi:

Izinhlelo ezisuselwa eStarch zingakwazi ukwenza i-gelatiinize, yakha ama-gels nge-Rheological Properties eyingqayizivele.
Ama-Grash Gels abalulekile embonini yokudla yezicelo zokuqina kanye ne-gelling.

Isicelo se-5.Industrial:

Sodium carboxymethyl cellulose:

Kusetshenziswe kabanzi embonini yokudla njengomuntu omkhulu, ozinzile kanye nokuzithoba.
Isetshenziswa kakhulu emithi yezemithi ngenxa yezakhiwo zayo zokubopha kanye nokuhlukaniswa kwezimpawu zokuqanjwa kwethebhulethi.
Kutholakala emikhiqizweni ehlukahlukene yokunakekelwa komuntu siqu efana namazinyo namazinyo kokhokhi.

Isitashi:

Isithako esiyinhloko embonini yokudla, inemiphumela yokuqina, ukucekelwa phansi kanye nemiphumela.
Kusetshenziswe ekukhiqizweni kwamapulasitiki angenakubonwa futhi njengomthombo woshukela ovuthayo ekukhiqizeni i-ethanol.
Ukuthambisa nokuhlanganisa embonini yamaphepha.

I-6. I-BiodeGreade:

Sodium carboxymethyl cellulose:

I-CMC iyi-biodegradable futhi ngenxa yalokho inezakhiwo ezinobungane bemvelo.
Ukusetshenziswa kwayo ezimbonini ezahlukahlukene kuhambisana nesidingo esikhulayo sezinto ezizinzile nezemvelo.

Isitashi:

Isitashi futhi sine-biodegradable, sikwenza kube ukukhetha okufanele kwezicelo ezinobungane bemvelo.
I-biodegradeabilibility yezinto ezisetshenziselwa isitashi zisiza ukunciphisa umthelela wezemvelo.

7. Ukusebenza okwakha amafilimu:

Sodium carboxymethyl cellulose:

I-CMC ingakha amafilimu ngamandla amahle emishini nokuvumelana nezimo.
Le mpahla isetshenziswa ekukhiqizweni kwamafilimu adliwayo nokumboza ukudla.

Isitashi:

Ifilimu lesitashi lenziwa ngenqubo ye-gelatinization.
Lawa mafilimu athola uhlelo lokusebenza ekupakisheni, lapho kukhethwa khona izinto ze-biodegradable.

8. Ukuqhutshwa:

Sodium carboxymethyl cellulose:

Izixazululo ze-CMC zibonisa izinga elithile lokuqhutshwa ngenxa yokuba khona kwamaqembu e-carboxyl.
Le mpahla iyaxhashazwa kuzinhlelo ezithile, njengezimboni ze-electrochemical.

Isitashi:

Isitashi asinakho okuphambili kukagesi.

9. Isiphetho:

I-CMC ne-Starch yehluka ngesakhiwo, imvelaphi, izakhiwo kanye nezinhlelo zokusebenza. I-CMC isuselwa ku-cellulose, ingukuphazanyiswa kwamanzi, inendlela yokuziphatha ye-pseudoplastic, futhi isetshenziswa kabanzi kwizimboni zokudla, ezenza imithi kanye nezimboni. Isitashi yi-polysaccharide engafakwanga emanzini abandayo kepha ama-gels lapho efudumele, okwenza kubalulekile ekudleni, emaphepheni nasezimbonini ezipakisha. Kokubili i-CMC nesitashishi kufaka isandla ekwakhiweni kwezinto ezizinzile nezinama-bioderhradable, ngokuhambisana nokugcizelelwa kwembulunga yonke kwizixazululo ezinobungane bemvelo. Ukuqonda lokhu kwehluka kungakusiza wenze izinqumo ezinolwazi lapho ukhetha izinto ezifanele zohlelo oluthile lwezimboni.
