Yini ukusetshenziswa okuyinhloko kwe-carboxymethyl cellulose?

I-Carboxymethyl Cellulose (CMC), eyaziwa nangokuthi yi-cellulose gum, iyindawo eguquguqukayo ethola izinhlelo zokusebenza kuyo yonke imboni ehlukahlukene ngenxa yezakhiwo zayo ezihlukile ngenxa yezakhiwo zayo ezihlukile ngenxa yezakhiwo zayo ezihlukile ngenxa yezakhiwo zayo ezihlukile ngenxa yezakhiwo zayo ezihlukile ngenxa yezakhiwo zayo ezihlukile ngenxa yezakhiwo zayo ezihlukile.

Isingeniso se-carboxymethyl cellulose (CMC)
I-Carboxymethyl Cellulose iyi-cellulose etholwa ngamanzi etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. Kukhiqizwa ukuguqulwa kwamakhemikhali kwe-cellulose ngokusebenzisa ukwethulwa kwamaqembu e-carboxymethyl (-ch2-cooh) kwi-cellulose backbone. Lokhu kuguqulwa kunikeza izakhiwo ezihlukile ku-CMC, okwenza kube yigugu kuzinhlelo zokusebenza eziningi zezimboni.

Chemistry of carboxymethyl cellulose
Inqubo ye-carboxymetyration ifaka ukusabela kwe-cellulose nge-chlorose acid noma usawoti wayo we-sodium phambi kwe-alkali, ngokujwayelekile i-sodium hydroxide. Lokhu kusabela kuholela ekufakwe esikhundleni samaqembu e-hydroxyl kwi-cellulose backbone enamaqembu e-carboxymethyl, okuholela ekwakhekeni kwe-carboxymethyl cellulose.

Izinga lokufaka esikhundleni (DS), elisho inani elijwayelekile lamaqembu e-carboxymethyls ngeyunithi ye-anhydroglucose e-cellulose, ethonya izakhiwo ze-CMC. Amanani aphezulu we-DS aholele ekukhuliseniseni okukhulayo nokuvunywa emanzini.

Izakhiwo ze-carboxymethyl cellulose
I-Carboxymethyl Cellulose ikhombisa izakhiwo ezimbalwa ezibalulekile ezenza zilungele izinhlelo ezahlukahlukene zokusebenzisa:

I-Solubinity yamanzi: I-CMC incane kakhulu emanzini, yakha izixazululo ezicacile, ezibonakalayo.
I-Viscosity: I-Viscosity yayo ingalawulwa kalula ngokulungiswa kwamapharamitha afana nokuhlushwa, isilinganiso sokufakwa esikhundleni, kanye no-pH.
Ukukhamulwa ifilimu: I-CMC ingakha amafilimu aguqukayo futhi avele obala lapho esomi, okwenza kube lusizo ezingeni lokusebenzisa imali ehlukahlukene.
Umenzeli wokuqina: Kusebenza njenge-ejenti esebenza kahle, ama-emulsions arving kanye nokumiswa kwebanga elibanzi le-PH.
I-Pseudoplallimaity: I-CMC ibonisa indlela yokuziphatha encipha kancane, okusho ukuthi i-viscosity yayo inciphisa ngaphansi kwengcindezi ye-shear, lula izinqubo zokupompa kanye nokwenza uhlelo lokusebenza.
Ukuvumelana: kuyahambelana nezinye izithako ezisetshenziswa kakhulu ekudleni, emikhakheni, kanye nokunakekelwa komuntu siqu.

Ukusetshenziswa okuyinhloko kweCarboxymethyl Cellulose

1.Ngakho imboni yokudla, i-CMC isebenzisa izinhloso eziningi:

Ukuqina kanye nomenzeli wokuzinza: Kusetshenziswa emikhiqizweni yokudla efana nososo, ukugqoka, kanye nemikhiqizo yobisi ukuthuthukisa ukubonakala nokuqina.
I-Tecumeture Modifier: I-CMC ithuthukisa ukuthungwa kwe-ayisikhilimu, i-yogurt, nemikhiqizo yokubhaka ngokulawula ukugcinwa komswakama nokuvimbela i-syneresis.
Ukufakwa esikhundleni samafutha: Ingasetshenziswa njengoMvuselele Onodoti onamafutha amancane noma ancishisiwe wokudla kwamakhalori.
I-Gluten-Free Baking: I-CMC ivame ukuqashwa ekubhaka kwamahhala-i-gluten

I-2.CMC ithola izicelo ezibanzi emkhakheni wezemithi:

I-Agent yethebhulethi ebophayo: Isetshenziswa kakhulu njenge-binder yokwakheka kwethebhulethi ukudlulisa ubumbano futhi kuqinisekisa ubuqotho bethebhulethi.
Umenzeli osomisayo: I-CMC imisa izidakamizwa ezingafakwanga ekwakhiweni koketshezi, iqinisekisa ukusatshalaliswa okufanayo kanye ne-dosing enembile.
I-VisCosity Modifier: Ngokuyaziswa kwezihloko ezinjengamakhilimu kanye nama-lotion, i-CMC isebenza njengesiguquli se-viscosity, ukuthuthukisa ukusakazeka komkhiqizo nokuqina.
Izixazululo ze-Ophthalmic: I-CMC isetshenziswa ngamaconsi wamehlo kanye nezinyembezi zokufakelwa ukuhlinzeka ngokuthambekela futhi kwandise isikhathi sokuxhumana nge-ocular.

3.Imikhiqizo yokunakekelwa komuntu siqu, i-CMC isebenza imisebenzi ehlukahlukene:

I-Shirener: Kuthuthumela ama-shampoos, ama-conditioners, kanye nokuhlanza umzimba, ukuthuthukisa ukuthungwa kwawo kanye nokwenza ngcono ulwazi lomsebenzisi.
I-Emulsion Stabilizer: CMC izinza ama-emulsion kumakhilimu, ama-lotion, kanye nezimonyo, ukuvimbela ukuhlukaniswa kwesigaba nokugcina ukungaguquguquki komkhiqizo.
I-Ejenti Yokumiswa: I-CMC imisa izinhlayiya ezingafakwanga ekwakhiweni kwamazinyo, ukuqinisekisa ukusatshalaliswa okufanayo kwama-abresive agents kanye nezithako ezisebenzayo.

I-4.Beyond The Food, Pharmaceutical, kanye nemikhakha yokunakekelwa komuntu siqu, i-CMC inokusetshenziswa kwezimboni:

Imboni yephepha: I-CMC iqashwa njengesengezo esimanzi esisemaphethelweni sokuthuthukisa amandla ephepha, ukugcinwa kwama-filler kanye nemibala, kanye nokudonsa.
Imboni yendwangu: Isebenza njenge-ejenti yezandla, ihlinzeka nge-studify yesikhashana kwimichilo nezindwangu ngesikhathi sokuluka.
Ukushayela uwoyela: olwela uwoyela wokushayela uwoyela, i-CMC isebenza njenge-viscosifier kanye nokulahleka koketshezi, ukuthuthukisa ukudonsa kahle kanye nokuqina komthombo.
Amapende nezimbozo: I-CMC isetshenziswa njenge-ejenti yokuqina nokuzinza kumapende asuselwa emanzini kanye nokumboza, ngcono ukugeleza kwalo kanye nokuvimbela ukugcwala.
5. Ezinye izinhlelo zokusebenza
Ama-detergents: I-CMC yengezwa ezihlalweni kanye nemikhiqizo yokuhlanza njengomuntu omkhulu kanye ne-Stabilizer, ithuthukisa ukusebenza kwayo nokubukeka kwayo.
Adhesives: Isetshenziswa ekwakhiweni okunamathela ukuguqula i-viscosity, ukuthuthukisa ama-tack, futhi kuthuthukise amandla e-bond.
Ukuthwebula izithombe: Ku-Photographic Film Coatings, i-CMC isebenza njenge-binder, iqinisekisa ukusakazwa okufanayo kwamakhompiyutha abucayi nokukhanya esisekelweni sefilimu.

I-Carboxymethyl Cellulose, ngezakhiwo zayo ezihlukile nezicelo eziguquguqukayo, idlala indima ebalulekile kuyo yonke imboni ehlukahlukene. Ukusuka ekudleni nasemikhakheni emikhiqizweni yokunakekelwa komuntu siqu nezinqubo zezimboni, i-CMC isebenza njengesengezo esibalulekile, ukuthuthukisa ukusebenza komkhiqizo, ukuqina nokusebenza. Ukusetshenziswa kwayo okusakazekile kugcizelela ukubaluleka kwayo njengesithako esibalulekile ekukhiqizweni kwanamuhla kwezenzo. Njengoba ucwaningo nobuchwepheshe kuyaqhubeka ukuqhubekisela phambili, ukusetshenziswa kwe-carboxymethyl celtule
