Sodium carboxymethyl cellulose tau lees paub tias yog khoom noj khoom haus zoo.Nws tau txais hauv kuv lub teb chaws hauv xyoo 1970 thiab tau siv dav hauv xyoo 1990.Nws yog qhov siv ntau tshaj plaws thiab ntau tshaj plaws ntawm cellulose hauv ntiaj teb niaj hnub no.
Kev siv yooj yim
Nws yog siv los ua cov thickener hauv kev lag luam khoom noj khoom haus, ua cov khoom siv tshuaj hauv kev lag luam kws tshuaj, thiab ua cov ntawv khi thiab cov tshuaj tiv thaiv kev hloov pauv hauv kev lag luam tshuaj niaj hnub.Nyob rau hauv kev lag luam luam ntawv thiab dyeing, nws yog siv los ua ib qho kev tiv thaiv colloid rau sizing tus neeg saib xyuas thiab luam ntawv muab tshuaj txhuam, thiab lwm yam. Nws tuaj yeem siv los ua cov roj fracturing kua hauv kev lag luam petrochemical.Nws tuaj yeem pom tias sodium carboxymethyl cellulose muaj ntau yam kev siv.
Kev siv CMC hauv Khoom Noj
Kev siv cov ntshiab CMC hauv cov zaub mov tau pom zoo los ntawm FAO thiab WHO.Nws raug pom zoo tom qab nruj heev kev tshawb fawb lom thiab tshuaj lom neeg thiab kev sim.Kev noj qab haus huv thoob ntiaj teb tus qauv (ADI) yog 25mg / (kg·d), uas yog, txog 1.5 g / d rau ib tus neeg.Nws tau raug tshaj tawm tias tsis muaj cov tshuaj tiv thaiv kab mob toxic thaum qhov kev xeem tau nce mus txog 10 kg.CMC tsis yog tsuas yog ib qho zoo emulsion stabilizer thiab thickener nyob rau hauv daim ntawv thov zaub mov, tab sis kuj muaj zoo heev khov thiab melting stability, thiab tuaj yeem txhim kho qhov tsw ntawm cov khoom thiab ntev lub sij hawm cia.Qhov ntau npaum li cas ntawm cov kua mis, ice cream, ice cream, jelly, dej haus thiab cov kaus poom yog li 1% mus rau 1.5%.CMC kuj tuaj yeem tsim kom muaj kev ruaj khov emulsion dispersion nrog vinegar, soy sauce, zaub roj, kua txiv hmab txiv ntoo, gravy, kua zaub, thiab lwm yam. Qhov ntau npaum li cas yog 0.2% mus rau 0.5%.Hauv particular, nws muaj emulsifying zoo heev rau tsiaj thiab zaub roj, proteins thiab aqueous daws, ua rau nws tsim ib homogeneous emulsion nrog cov khoom ruaj khov.Vim tias nws txoj kev nyab xeeb thiab kev ntseeg tau, nws qhov ntau npaum li cas tsis txwv los ntawm lub teb chaws cov zaub mov kev nyiam huv tus qauv ADI.CMC tau tsim kho tsis tu ncua hauv cov khoom noj khoom haus, thiab nyob rau xyoo tas los no, kev tshawb fawb txog kev siv sodium carboxymethyl cellulose hauv kev tsim cawv kuj tau ua.
