Ubume be-sodium carboxymethyl cellulose

I-Methyl cellulosengokuqhelekileyo sisishunqulelo se-sodium carboxymethyl cellulose, eyeyaluhlobo lwekhompawundi yepolyanionic enonyibiliko olulungileyo lwamanzi. Phakathi kwazo, i-methyl cellulose ikakhulu ibandakanya i-methyl cellulose m450, i-methyl cellulose eguquliweyo, iBanga le-methyl cellulose yokutya, i-hydroxymethyl cellulose, njl. Kuyafaneleka ukukhankanya ukuba kwintsimi yesamente, i-methylcellulose inempembelelo ecacileyo yokunciphisa imixube yodaka, nayo ngenxa yesakhiwo esikhethekileyo se-methylcellulose.

Njengomxokelelwano omde othathelwe indawo cellulose, i-sodium carboxymethylcellulose ngokwayo inamalunga nama-27% ~ 32% yamaqela ayo e-hydroxyl ngendlela yamaqela e-methoxy, kunye neqondo lepolymerization yamabanga ahlukeneyosodium carboxymethylcellulosenayo yahlukile. Ubunzima be-molecular ngokuyinhloko bubandakanyeka ukusuka kwi-10,000 ukuya kwi-220,000 Da, kwaye iqondo eliphambili lokutshintshwa linani eliqhelekileyo lamaqela e-methoxy, ahlukeneyo amacandelo e-anhydroglucose axhunyiwe kwikhonkco.

I-sodium carboxymethyl cellulose okwangoku isetyenziswa ngokubanzi kumalungiselelo athile ezihloko, kunye nezithambiso kunye ne-methyl cellulose yokutya, ezidla ngokuba zingenatyhefu, zingavezi kwaye zingacaphukisi. I-Methyl cellulose Su yinto engeyiyo i-caloric,
