Uyini umehluko phakathi kwe-CMC ne-MC?

I-CMC kanye ne-MC kokubili okuphuma ku-cellulose okuvame ukusetshenziswa njengama-thickeners, ama-binders, kanye neziqinisi ezinhlelweni ezisetshenziswayo ezihlukahlukene, okuhlanganisa izimboni zokudla, ezekhemisi, nezokunakekela komuntu siqu. Nokho, kunomehluko othile phakathi kwalokhu okubili okufanele ukuphawulwe.

I-CMC, noma i-Carboxymethyl Cellulose, i-polymer encibilika emanzini etholakala ku-cellulose. Idalwe ngokuphendula i-cellulose nge-sodium chloroacetate futhi iguqule amanye amaqembu e-hydroxyl ku-cellulose abe amaqembu e-carboxymethyl. I-CMC isetshenziswa kakhulu emikhiqizweni yokudla, njengezimpahla ezibhakwayo, imikhiqizo yobisi, namasoso, kanye nemikhiqizo yokunakekelwa komuntu siqu kanye nemithi.

I-MC, noma i-Methyl Cellulose, nayo iyi-polymer encibilika emanzini etholakala ku-cellulose. Idalwa ngokuphendula i-cellulose nge-methyl chloride futhi iguqule amanye amaqembu e-hydroxyl ku-cellulose abe amaqembu e-methyl ether. I-MC isetshenziswa njenge-thickener, binder, kanye ne-emulsifier ezinhlelweni ezihlukene, okuhlanganisa emikhiqizweni yokudla, njengamasoso, okokugqoka, nama-dessert afriziwe, nasezikhiqizweni zemithi nemikhiqizo yokunakekelwa komuntu siqu.

Umehluko owodwa obalulekile phakathi kwe-CMC ne-MC izici zabo zokuncibilika. I-CMC incibilika kalula emanzini kune-MC, futhi ingakha isixazululo esicacile, esibonakalayo ekugxilweni okuphansi. I-MC, ngakolunye uhlangothi, ngokuvamile idinga ukugxila okuphezulu kanye/noma ukushisisa ukuze incibilike ngokuphelele emanzini, futhi izisombululo zayo zingase zingabonakali noma zibe namafu.

Omunye umehluko ukuziphatha kwabo ezimweni ze-pH ezihlukene. I-CMC izinze kakhulu ezimeni ezine-asidi futhi ingabekezelela ububanzi be-pH ebanzi kune-MC, engabhidlika futhi ilahlekelwe izici zayo zokujiya ezindaweni ezine-asidi.

Kokubili i-CMC kanye ne-MC kukhona okuphuma ezintweni ezihlukahlukene kwe-cellulose okunezinto eziningi eziwusizo zezinhlelo zokusebenza ezihlukahlukene. Ukukhetha ukuthi iyiphi ozoyisebenzisa kuzoncika ezidingweni ezithile zohlelo lokusebenza kanye nezici zokusebenza ezifiselekayo.
