Ib qho yooj yim Soluble hauv dej 9004-32-4 Zaub Mov Qib Sodium Carboxymethyl Cellulose (CMC)
Product details
MF: C8H16NaO8
CAS: 9085-26-1 Nr
1.Sodium carboxymethylcellulose (CMC) yog carboxymethylated derivative ntawm cellulose, tseem hu ua cellulose kua nplaum.Nws belongs rau anionic cellulose chemicalbook vitamin ether thiab yog qhov tseem ceeb tshaj plaws ionic cellulose kua nplaum.Nws feem ntau yog ib qho anionic polymer compound npaj los ntawm cov tshuaj tiv thaiv ntawm ntuj cellulose nrog caustic soda thiab monochloroacetic acid.Qhov hnyav molecular ntawm qhov sib xyaw ua ke ntawm ntau txhiab mus rau lab.
2.CMC yog dawb los yog milky fibrous hmoov los yog hais, nrog ib tug ceev ntawm 0.5-0.7 g / cubic centimeter, yuav luag odorless, tasteless, thiab hygroscopic.Nws yog ib qho yooj yim rau disperse nyob rau hauv dej mus rau hauv lub pob tshab colloidal tov thiab insoluble nyob rau hauv cov organic solvents xws li ethanol.pH ntawm 1% aqueous tov yog 6.5 ~ 8.5.Thaum ph> 10 lossis <5, viscosity ntawm slurry txo qis, thiab qhov ua tau zoo yog qhov zoo tshaj plaws thaum ph = 7.Rau thermal stability, viscosity nce sai dua 20chemical phau ntawv ℃, thiab hloov maj mam ntawm 45 ℃.Lub sijhawm ntev cua sov siab tshaj 80 ℃ tuaj yeem ua rau nws cov colloid thiab txo nws cov viscosity thiab cov khoom.Soluble nyob rau hauv dej, pob tshab kua;Nws yog ruaj khov heev nyob rau hauv alkaline kua, thiab nws yog ib qho yooj yim rau hydrolyze nyob rau hauv cov ntaub ntawv ntawm acid.Cov dej nag yuav tshwm sim thaum tus nqi pH yog 2-3, thiab nag lossis daus kuj yuav tshwm sim nyob rau hauv rooj plaub ntawm cov ntsev ntau ntau.Khoom CMC yog qhov ruaj khov rau lub teeb thiab chav tsev kub, thiab tuaj yeem khaws cia rau lub sijhawm ntev hauv qhov chaw qhuav.
Daim ntawv thov
1.Sodium carboxymethyl cellulose tuaj yeem siv ua thickener, stabilizer thiab emulsifier.Cov ntawv thov tshwj xeeb yog raws li hauv qab no: 1 Daim Ntawv Thov CMC hauv cov khoom noj khoom haus CMC muaj cov yam ntxwv ntawm thickening, emulsifying, shaping, dej tuav, stability thiab lwm yam.
2. Ntxiv CMC rau cov zaub mov tuaj yeem txo cov nqi ntawm cov khoom noj, txhim kho qib ntawm cov zaub mov, txhim kho cov saj ntawm cov zaub mov, thiab txuas ntxiv lub sij hawm lav zoo ntawm cov zaub mov.Nws yog ib qho khoom noj khoom haus zoo tshaj plaws hauv kev lag luam zaub mov.Nws tuaj yeem siv dav hauv txhua yam khoom siv thiab cov dej haus, cov kaus poom, khoom qab zib, khoom qab zib, nqaij khoom, biscuits, instant noodles, yob noodles, ceev boiled zaub mov, ceev-kub tsw khoom noj txom ncauj, soymilk, yogurt, txiv laum huab xeeb, txiv hmab txiv ntoo tshuaj yej. Cov kua txiv hmab txiv ntoo thiab lwm yam khoom noj.
3.CMC muaj ntau hom kev siv thiab ntau npaum hauv cov khoom noj sib txawv.
