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-polymers eglucose: i-amylose (amaketanga aqondile) kanye ne-amylopectin (izakhiwo zamaketanga 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 kwesitashi 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 nezicelo. 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.
