Sodium carboxymethyl cellulose

Sodium Carboxymethyl cellulose (CMC-NA) yog carboxymethylated derivative ntawm cellulose ntawm cov pos hniav. Sodium Carboxymethyl cellulose feem ntau yog anionic polymer compound npaj npaj los ntawm kev rov ua kom lub cev nqaij tawv nqaij tawv nqaij, nrog lub cev hnyav dua los ntawm ntau txhiab rau lab. CMC-NA yog dawb fibrous los yog granular hmoov los yog tsw, hygroscopic, yooj yim rau tawg hauv dej los ua ib qho kev daws teeb meem pob tshab colloidal.

2. Lub cev thiab tshuaj lom neeg

CMC-NA rau luv luv, dawb rau daj ntseg hmoov, granrous tshuaj, yooj yim soluble hauv dej, yooj yim solroscise kua thaum nws yog nruab nrab lossis alkaline. Ruaj khov rau cov tshuaj, lub teeb thiab kub. Txawm li cas los xij, cov cua sov yog txwv rau 80 ° C, thiab yog tias rhuab ntev saum toj no 80 ° C, lub viscosity yuav poob thiab nws yuav insoluble hauv dej. Nws tus txheeb ze ceev yog 1.60, thiab cov txheeb ze ntom ntawm flakes yog 1.59. Cov indexoral index yog 1.515. Nws hloov xim av thaum rhuab rau 190-205 ° C, thiab carbonizes thaum rhuab rau 235-248 ° C. Nws solubility hauv dej nyob ntawm cov qib hloov pauv. Insoluble hauv acid thiab dej cawv, tsis muaj nag los xij nyob rau hauv rooj plaub ntawm. Nws tsis yooj yim rau ferment, muaj cov zog emulsifying zog rau cov roj thiab siv quav ciab, thiab tuaj yeem khaws cia ntev ntev.
3. Daim ntawv thov tseem ceeb

Dav siv nyob rau hauv cov roj kev lag luam khawb cov khoom lag luam, cov tshuaj txhuam dej thiab cov khoom siv dej ua ke rau cov khoom lag luam flourment, thiab lwm yam. Mas siv nyob rau hauv dej kom huv sludge kev kho mob, uas tuaj yeem nce cov ntsiab lus zoo ntawm cov lim ncuav mog qab zib.

Sodium Carboxymethyl cellulose kuj yog ib hom tuab. Vim nws cov khoom siv ua haujlwm zoo, nws tau siv dav hauv kev lag luam khoom noj khoom haus, thiab nws kuj tau nce qib kev lag luam kom zoo thiab noj qab haus huv rau qee yam. Piv txwv li, vim nws qee yam thickening thiab emulsifying cov nyhuv, nws tuaj yeem siv los ua kom muaj cov dej khov yogurt ntawm yogurt system; Vim hais tias ntawm nws tej yam hydrophilicity thiab cov khoom siv nyiaj rov qab, nws tuaj yeem siv los txhim kho kev noj cov nplej zom xws li mov ci thiab ci ci. Zoo, Rub lub neej ua kom tiav ntawm cov khoom noj ntawm cov nplej zom, thiab txhim kho lub saj; Vim tias nws muaj qee qhov nyhuv gel, nws yog conducive rau kev tsim kom zoo dua ntawm gel hauv cov zaub mov, yog li nws tuaj yeem siv los ua jelly thiab jam; Nws kuj tseem siv tau ua cov txheej txheem ua yeeb yaj kiab cov khoom siv tau sib xyaw ua ke, thiab vim nws yog cov khoom noj zoo tshaj plaws, nws yuav tsis ua rau muaj kev cuam tshuam zoo rau tib neeg kev noj qab haus huv. Yog li ntawd, cov khoom noj khoom haus Cmc-na, raws li cov zaub mov zoo tshaj plaws ntxiv, yog siv dav hauv cov zaub mov ua khoom noj.
