Qib Kev Hloov Chaw (DS tus nqi): Qib Kev Hloov Chaw (DS) yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm CMC. Nws sawv cev rau tus lej nruab nrab ntawm cov carboxymethyl hloov chaw hauv txhua chav glucose. Feem ntau, tus nqi DS yuav tsum nyob nruab nrab ntawm 0.6-1.2. Tus nqi DS qis dhau yuav cuam tshuam rau qhov dej yaj thiab cov nyhuv ua kom tuab ntawm CMC.

Qhov acidity lossis pH tus nqi: Tus nqi pH ntawm CMC kua feem ntau yuav tsum nyob nruab nrab ntawm 6-8. Tus nqi pH qis dhau lossis siab dhau yuav cuam tshuam rau kev ruaj khov thiab kev siv cov nyhuv ntawm CMC.

Cov ntsiab lus tshauv: Cov ntsiab lus tshauv yog cov ntsiab lus ntawm cov khoom inorganic hauv CMC, uas feem ntau yuav tsum tsis pub tshaj 5%. Cov ntsiab lus tshauv siab dhau yuav cuam tshuam rau qhov solubility ntawm CMC thiab qhov zoo ntawm daim ntawv thov kawg.

Kev yaj: CMC yuav tsum yaj tag nrho hauv dej ntawm chav tsev kub kom tsim tau cov kua pob tshab, uas raug ncua. CMC uas yaj tsis zoo yuav muaj cov khoom tsis yaj lossis cov cellulose tsis zoo.

Cov hlau hnyav uas muaj: Cov hlau hnyav uas muaj nyob hauv AnxinCel®CMC yuav tsum ua raws li cov qauv hauv tebchaws lossis cov qauv kev lag luam. Feem ntau yuav tsum muaj cov hlau hnyav tag nrho uas muaj tag nrho cov hlau hnyav tsis pub tshaj 0.002%.

Cov cim qhia txog kab mob me me: CMC yuav tsum ua tau raws li cov qauv txwv tsis pub muaj kab mob me me. Nyob ntawm seb siv li cas, CMC hauv qib zaub mov, CMC hauv qib tshuaj, thiab lwm yam yuav tsum tau tswj hwm cov kab mob me me xws li cov kab mob me me, pwm, thiab E. coli kom nruj.

3. Cov qauv siv ntawm CMC

Cov teb sib txawv muaj cov kev cai sib txawv rau CMC, yog li ntawd yuav tsum tau tsim cov qauv siv tshwj xeeb. Cov qauv siv feem ntau suav nrog:

Kev lag luam zaub mov: CMC qib zaub mov yog siv rau kev ua kom tuab, ruaj khov, emulsification, thiab lwm yam, thiab yuav tsum ua kom tau raws li cov qauv kev nyab xeeb zaub mov, xws li tsis muaj tshuaj lom, tsis muaj teeb meem, tsis ua xua, thiab muaj dej zoo solubility thiab viscosity. CMC kuj tseem siv tau los txo cov rog thiab txhim kho qhov saj thiab kev ntxhib los mos ntawm zaub mov.

Kev lag luam tshuaj: Raws li cov tshuaj siv ntau, cov tshuaj CMC hauv kev lag luam tshuaj yuav tsum tau tswj hwm cov khoom tsis huv, cov ntsiab lus microbial, tsis muaj tshuaj lom, tsis ua xua, thiab lwm yam. Nws cov haujlwm tseem ceeb suav nrog kev tso tawm tshuaj, thickening, adhesives, thiab lwm yam.

Cov tshuaj txhua hnub: Hauv cov tshuaj pleev ib ce, cov tshuaj ntxuav thiab lwm yam tshuaj txhua hnub, CMC yog siv los ua cov khoom siv tuab, stabilizer, suspending agent, thiab lwm yam, thiab yuav tsum muaj dej zoo solubility, viscosity thiab stability.

Kev lag luam ua ntawv: CMC yog siv los ua cov nplaum, cov neeg sawv cev txheej, thiab lwm yam hauv cov txheej txheem ua ntawv, xav tau viscosity siab, ruaj khov thiab qee qib ntawm kev tswj cov dej noo.

Kev siv roj av: CMC yog siv los ua cov kua ntxiv rau hauv cov kua dej hauv cov roj av kom ua rau viscosity thiab txhim kho fluidity. Cov ntawv thov no muaj cov kev xav tau siab rau CMC solubility thiab viscosity-nce peev xwm ntawm.

Nrog rau kev txhim kho tas mus li ntawm kev tshawb fawb thiab thev naus laus zis,CMC, ua ib yam khoom siv polymer ntuj, yuav txuas ntxiv nthuav nws cov cheeb tsam siv. Thaum tsim cov qauv zoo ntawm cov ntaub ntawv CMC, ntxiv rau kev xav txog nws cov khoom siv lub cev thiab tshuaj, nws tseem tsim nyog los xav txog nws cov kev xav tau daim ntawv thov kom ntseeg tau tias nws tuaj yeem ua tau raws li cov kev xav tau ntawm ntau qhov chaw lag luam. Kev tsim cov qauv kom ntxaws thiab meej yog ib txoj hauv kev tseem ceeb los xyuas kom meej tias cov khoom AnxinCel®CMC zoo thiab siv tau zoo, thiab nws tseem yog qhov tseem ceeb rau kev txhim kho kev sib tw ua lag luam ntawm cov ntaub ntawv CMC.
