Uyini umehluko phakathi kwe-CMC nesitashi?

I-Carboxymethylcelcelcellellulose (CMC) kanye nesitashi zombili ama-polysaccharides, kepha zinezinhlaka ezahlukahlukene, izakhiwo kanye nezinhlelo zokusebenza.

Ukwakheka kwama-molecular:

1. I-Carboxymethylcellellulose (CMC):

I-Carboxymethylcellellellulose ingukususelwa kwe-cellulose, i-polymer eqondile ehlanganiswe ama-glucose amayunithi axhunywe ngamabhondi angu-β-1,4-glycosidic. Ukuguqulwa kwe-cellulose kufaka phakathi ukwethulwa kwamaqembu e-carboxymethyl ngokusebenzisa ukusheshisa, ukukhiqiza i-carboxymethylcellellulose. I-Carboxymethyl Group yenza amanzi e-CMC ancibilike futhi anikeze izakhiwo ezihlukile ze-polymer.

2. Isitashi:

Isitashi i-carbohydrate ehlanganiswe ama-glucose amayunithi axhumeke ama-α-1,4-glycosidic bond. Kuyi-polymer yemvelo etholakala ezitshalweni ezisetshenziswa njengendawo yokugcina amandla. Ama-molecule e-starch ngokuvamile akhiwa ngezinhlobo ezimbili zama-polymers we-glucose: ama-amylose (amaketanga aqondile) ne-amylopectin (izakhiwo ze-chanathi ezihlanganisiwe).

Izakhiwo ezibonakalayo:

1. I-Carboxymethylcellellulose (CMC):

I-Solubinity: I-CMC incane amanzi ngenxa yokuba khona kwamaqembu e-carboxymethyl.

I-Viscosity: Ibonisa i-viscosity ephezulu ngesixazululo, okwenza kube yigugu kuzicelo ezahlukahlukene ezifana nokusebenza kokudla kanye nemithi.

Ukusobala: Izisombululo ze-CMC zivame ukucaca.

2. Isitashi:

I-Solubinity: Isitashi sendabuko siyafakwa emanzini. Kudinga i-gelatinization (ukufudumeza emanzini) ukuze kuncibilike.

I-Viscosity: I-Starch Paste inokuqonda, kepha ngokuvamile iphansi kune-CMC.

Ukusobala: Ama-starch pastes avame ukuba opaque, futhi izinga le-opacity lingahluka ngokuya ngohlobo lwesitashi.

Umthombo:

1. I-Carboxymethylcellellulose (CMC):

I-CMC yenziwe ngokujwayelekile kusuka ku-cellulose kusuka kwimithombo yezitshalo enjenge-solip yokhuni noma ukotini.

2. Isitashi:

Izitshalo ezinjenge-corn, ukolweni, amazambane nelayisi zicebile ngesitashi. Kuyisithako esiyinhloko ekudleni okuningi okuyisisekelo.

Inqubo yokukhiqiza:

1. I-Carboxymethylcellellulose (CMC):

Ukukhiqizwa kwe-CMC kufaka phakathi ukuhanjiswa kwe-etherhation of cellulose nge-chlorosetic acid ku-alkaline medium. Lokhu kusabela kuphumela ekushintshelweni kwamaqembu e-hydroxyl eCellulose enamaqembu e-carboxymethyl.

2. Isitashi:

Ukukhishwa kwesitashi kuhilela ukwehlisa amaseli wezitshalo nokuhlukanisa ama-granule wesitashi. Isitashi esikhishwe ngaphandle kwezinqubo ezahlukahlukene, kufaka phakathi ukuguqulwa kanye ne-gelatinization, ukuthola izakhiwo ezifiselekayo.

Inhloso kanye nesicelo:

1. I-Carboxymethylcellellulose (CMC):

Imboni yokudla: I-CMC isetshenziswa njengesikhulu, i-stabilizer kanye ne-emulsifier ekudleni okuhlukahlukene.

Izemithi: Ngenxa yokubopha kwayo okubophayo kanye nokugqashuka kwezakhiwo, kuthola ukusetshenziswa ekwakhiweni kwemithi.

Ukushayela uwoyela: I-CMC isetshenziswa uketshezi lokumba uwoyela ukulawula i-RHEOLOGY.

2. Isitashi:

Imboni yokudla: isitashi yingxenye eyinhloko yokudla okuningi futhi isetshenziswa njenge-ejenti yokuqina, i-ejenti ye-gelling ne-stabilizer.

Imboni yendwangu: Isitashi sisetshenziswa kuzincwadi zezindwangu ukuhlinzeka ngamandla ezindwangu.

Imboni yamaphepha: Isitashi sisetshenziswa emaphaketheni ukwandisa amandla ephepha futhi sithuthukise izakhiwo ezingaphezulu.

Yize i-CMC kanye nesitashi zombili ama-polysaccharides, anomehluko ekubumbeni kwamangqamuzana, izakhiwo ezibonakalayo, imithombo, izinqubo zokukhiqiza kanye nezinhlelo zokusebenza. I-CMC ingukuncibilika kwamanzi futhi i-viscous kakhulu futhi ivame ukuthandwa kuzicelo ezidinga lezi zindawo, ngenkathi isitashi siyinto eguquguqukayo esetshenziswa kabanzi kwizimboni zokudla, ezindwangu nezephepha. Ukuqonda lo mehluko kubalulekile ekukhetheni i-polymer efanelekile yezicelo ezithile zezimboni nezentengiso.
