Iyini i-sodium cmc?

I-Sodium Carboxymethyl Cellulose (CMC) iyi-polymer encibilika emanzini etholakala ku-cellulose, okuyi-polysaccharide eyenzeka ngokwemvelo etholakala ezindongeni zamaseli ezitshalo. I-CMC ikhiqizwa ngokwelapha i-cellulose nge-sodium hydroxide ne-monochloroacetic acid, okuholela ekubeni umkhiqizo onamaqembu e-carboxymethyl (-CH2-COOH) anamathiselwe kumgogodla we-cellulose.

I-CMC ivamise ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi ukudla, ezemithi, ukunakekelwa komuntu siqu, kanye nezicelo zezimboni, ngenxa yezakhiwo zayo ezihlukile. Emikhiqizweni yokudla, i-sodium CMC isebenza njenge-ejenti yokuqina, i-stabilizer, ne-emulsifier, ithuthukisa ukuthungwa, ukungaguquguquki, nempilo yeshalofu. Kwezemithi, isetshenziswa njenge-binder, disintegrant, kanye ne-viscosity modifier kumaphilisi, okokumiswa, namafutha okugcoba. Emikhiqizweni yokunakekelwa komuntu siqu, isebenza njenge-thickener, moisturizer, kanye ne-ejenti eyenza ifilimu kuzimonyo, ama-lotions, kanye nomuthi wokuxubha. Ezinhlelweni zezimboni, i-sodium CMC isetshenziswa njenge-binder, i-rheology modifier, kanye ne-ejenti yokulawula ukulahlekelwa uketshezi kumapende, okokuhlanza, izindwangu, noketshezi lokumba uwoyela.

I-Sodium CMC ikhethwa ngaphezu kwezinye izinhlobo ze-CMC (ezifana ne-calcium CMC noma i-potassium CMC) ngenxa yokuncibilika kwayo okuphezulu nokuzinza ezixazululweni ezinamanzi. Itholakala emabangeni ahlukahlukene kanye nama-viscosities ukuze ivumelane nezinhlelo zokusebenza ezahlukene kanye nezidingo zokucubungula. Sekukonke, i-sodium CMC iyisengezo esisebenza ngezindlela eziningi nesisetshenziswa kabanzi esinezinhlelo zokusebenza eziningi kuzo zonke izimboni ezahlukahlukene.
