Uyini umehluko phakathi kwe-CMC nesitashi?

I-Carboxymethylcellulose (CMC) kanye nesitashi womabili ama-polysaccharides, kodwa anezakhiwo ezihlukene, izakhiwo kanye nokusetshenziswa kwawo.

Ukwakheka kwamangqamuzana:

1. I-Carboxymethylcellulose (CMC):

I-Carboxymethylcellulose iphuma ku-cellulose, i-polymer eqondile eyakhiwe amayunithi e-glucose axhunywe ngamabhondi e-β-1,4-glycosidic.Ukuguqulwa kwe-cellulose kuhilela ukwethulwa kwamaqembu e-carboxymethyl ngokusebenzisa i-etherification, ukukhiqiza i-carboxymethylcellulose.Iqembu le-carboxymethyl lenza i-CMC incibilike emanzini futhi inikeze izakhiwo ezihlukile ze-polymer.

2. Isitashi:

Isitashi icarbohydrate eyakhiwe amayunithi eglucose axhunywe amabhondi e-α-1,4-glycosidic.Kuyi-polymer yemvelo etholakala ezitshalweni ezisetshenziswa njengenhlanganisela yokugcina amandla.Ama-molecule esitashi ngokuvamile akhiwa izinhlobo ezimbili zama-polymer e-glucose: i-amylose (amaketanga aqondile) kanye ne-amylopectin (izakhiwo zamaketango egatsha).

Izinto ezibonakalayo:

1. I-Carboxymethylcellulose (CMC):

Ukunyibilika: I-CMC iyancibilika emanzini ngenxa yokuba khona kwamaqembu e-carboxymethyl.

I-Viscosity: Ibonisa i-viscosity ephezulu ekuxazululeni, iyenze ibe yigugu ezinhlelweni ezihlukahlukene ezifana nokucubungula ukudla kanye nemithi.

Ukungafihli: Izixazululo ze-CMC zivame ukuba sobala.

2. Isitashi:

Ukunyibilika: isitashi somdabu asincibiliki emanzini.Kudinga i-gelatinization (ukushisa emanzini) ukuze incibilike.

I-Viscosity: I-starch paste ine-viscosity, kodwa ngokuvamile iphansi kune-CMC.

Ukungafihli: Okunamathiselwe isitashi kuvame ukufiphala, futhi izinga lokungabonakali lingahluka kuye ngohlobo lwesitashi.

umthombo:

1. I-Carboxymethylcellulose (CMC):

I-CMC ngokuvamile yenziwa nge-cellulose emithonjeni yezitshalo efana ne-pulp yokhuni noma ukotini.

2. Isitashi:

Izitshalo ezinjengommbila, ukolweni, amazambane kanye nelayisi kunothe ngesitashi.Kuyisithako esiyinhloko ekudleni okuningi okuyisisekelo.

Inqubo Yokukhiqiza:

1. I-Carboxymethylcellulose (CMC):

Ukukhiqizwa kwe-CMC kuhilela ukusabela kwe-etherification kwe-cellulose ne-chloroacetic acid endaweni ye-alkaline.Lokhu kusabela kuholela ekushintshweni kwamaqembu e-hydroxyl ku-cellulose ngamaqembu e-carboxymethyl.

2. Isitashi:

Ukukhishwa kwesitashi kuhilela ukudiliza amaseli ezitshalo nokuhlukanisa ama-starch granules.Isitashi esikhishiwe singabhekana nezinqubo ezihlukahlukene, okuhlanganisa ukuguqulwa kanye ne-gelatinization, ukuthola izakhiwo ezifiselekayo.

Inhloso kanye nesicelo:

1. I-Carboxymethylcellulose (CMC):

Imboni yokudla: I-CMC isetshenziswa njenge-thickener, stabilizer kanye ne-emulsifier ekudleni okuhlukahlukene.

Ezemithi: Ngenxa yezakhiwo zayo ezibophayo nezihlukanisayo, ithola ukusetshenziswa ekwakhiweni kwemithi.

Ukumba Kawoyela: I-CMC isetshenziswa oketshezini lokumba uwoyela ukulawula i-rheology.

2. Isitashi:

Imboni yokudla: Isitashi siyingxenye eyinhloko yokudla okuningi futhi sisetshenziswa njenge-ejenti yokuqina, i-gelling agent kanye ne-stabilizer.

Imboni yezindwangu: Isitashi sisetshenziswa ekulinganisweni kwezindwangu ukunikeza ukuqina ezindwangu.

Imboni yamaphepha: Isitashi sisetshenziswa ekwenzeni iphepha ukuze kwandiswe amandla ephepha futhi kuthuthukiswe izindawo ezingaphezulu.

Nakuba i-CMC nesitashi kokubili kuyi-polysaccharides, kunomehluko ekubunjweni kwamangqamuzana, izakhiwo zomzimba, imithombo, izinqubo zokukhiqiza kanye nokusetshenziswa.I-CMC iyancibilika emanzini futhi i-viscous kakhulu futhi ivame ukuthandwa ezinhlelweni ezidinga lezi zakhiwo, kuyilapho isitashi siyi-polysaccharide esebenza ngezindlela eziningi esetshenziswa kabanzi ezimbonini zokudla, zendwangu kanye nezamaphepha.Ukuqonda lo mehluko kubalulekile ekukhetheni i-polymer efanelekile yezinhlelo zokusebenza ezithile zezimboni nezentengiso.
