Sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose(Cmc), tseem hu ua:Lub sodiumCMC, cellulosepos hniav, CMC-NA, yog cellulose ether derivatives, uasyog qhov feem ntau siv thiab ntau tshaj plaws hauv ntiaj teb.Nws yog cellulosdaim icsNrog cov piam thaj flucose polymerization degree ntawm 100 txog 2000 thiab ib tug txheeb ze molecular loj ntawm 242.16. Dawb fibrous lossis granular hmoov. Tsis meej, tsis muaj, hygroscopic, insoluble hauv cov kuab tshuaj organic.

Cmcyog anionic cellulose ete, dawb los yog miluce dawb fibrous hmoov los yog ceev 0.5-0.7 g / cm3, yuav luag tsw, thiab hygroscopic. Yooj yim tawg rau hauv dej rau hauv lub pob tshab gel daws, insoluble hauv cov kuab tshuaj ethanol. Cov PHC ntawm 1% kev daws teeb meem yog 6.5Tom mu8.5. Thaum Ph> 10 lossis <5, lub viscosity ntawm cov kua nplaum yuav txo qis, thiab kev ua tau zoo tshaj plaws thaum ph = 7. Ruaj khov rau tshav kub, lub viscosity nce sai sai hauv qab 20 ° C, thiab hloov maj mam ntawm 45 ° C. Lub sijhawm ntev ntev saum toj no 80 ° C tuaj yeem yeem denature colloid thiab loj txo nws viscosity thiab kev ua tau zoo. Nws yog yooj yim soluble hauv dej thiab kev daws teeb meem yog pob tshab; Nws yog qhov ruaj khov nyob rau hauv kev daws teeb meem alkaline, thiab nws yooj yim hydrolyzed thaum nws ntsib acid. Nws yuav precipitate thaum lub p yog 2-3, thiab nws kuj yuav muaj kev cuam tshuam nrog polyvalent hlau ntsev rau nag lossis daus.

Daim ntawv thov

  1. Khoom Noj Qib CMC

Sodium carboxymethyl cellulose cmcTsis yog tsuas yog emulsion zoo stabilizer thiab cov tuab tuab hauv cov ntawv thov zaub mov, tab sis kuj tseem txhim kho qhov tsw zoo, thiab tuaj yeem txhim kho qhov tsw thiab tuaj yeem txuas lub sijhawm cia. Tus nqi siv nyob rau hauv kua mis kua roj, mis nyuj khov, dej khov, dej haus, thiab cov kaus poom yog li 1% rau 1.5%. CMC kuj tseem tuaj yeem ua ke nrog vinegar, zaub kua txiv, txiv hmab txiv ntoo, thiab lwm yam tshuaj pleev ib ce yog 0.2% mus rau 0.5%. Tshwj xeeb tshaj yog rau tsiaj thiab zaub roj, protein thiab aqueous daws, nws muaj emulsification zoo nkauj ua yeeb yam.

  1. Xab xab npum Qib CMC

Sodium Carboxymethyl Cellulose CMC tuaj yeem siv los ua cov tshuaj tiv thaiv av ntawm hydthetic fiber ntau, uas yog zoo dua li carboxymethyl fiber ntau.

  1. Roj Drilling qib CMC

Sodium Carboxymethyl cellulose CMC yuav siv tau los tiv thaiv cov roj cov roj ua cov av nkos stabilizer thiab dej-tuav tus neeg sawv cev hauv roj drilling. Kev noj ntawm txhua cov roj zoo yog 2.3t rau qhov dej ntiav thiab 5.6t rau cov qhov dej tob;
