Kodi sodium cmc ndi chiyani?

Sodium Carboxymethyl Cellulose (CMC) ndi polima wosungunuka m'madzi wochokera ku cellulose, yomwe ndi polysaccharide yachilengedwe yomwe imapezeka m'makoma a maselo a zomera. CMC imapangidwa pochiza cellulose ndi sodium hydroxide ndi monochloroacetic acid, zomwe zimapangitsa kuti pakhale chinthu chokhala ndi magulu a carboxymethyl (-CH2-COOH) omangiriridwa ku msana wa cellulose.

CMC imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala, chisamaliro chaumwini, ndi ntchito zamafakitale, chifukwa cha mawonekedwe ake apadera. Muzinthu zopangira chakudya, sodium CMC imagwira ntchito ngati chowonjezera kukhuthala, chokhazikika, ndi chowonjezera, kukonza kapangidwe, kusinthasintha, komanso nthawi yosungira. Muzinthu zopangira mankhwala, imagwiritsidwa ntchito ngati chomangirira, chochotsa, komanso chosintha kukhuthala m'mapiritsi, zosungunulira, ndi mafuta odzola. Muzinthu zopangira chisamaliro chaumwini, imagwira ntchito ngati chokhuthala, chonyowetsa, komanso chopangira filimu muzodzola, mafuta odzola, ndi mano otsukira mano. Muzinthu zopangira mafakitale, sodium CMC imagwiritsidwa ntchito ngati chomangirira, chosintha rheology, komanso chowongolera kutayika kwa madzi mu utoto, sopo, nsalu, ndi madzi obowola mafuta.

Sodium CMC imakondedwa kuposa mitundu ina ya CMC (monga calcium CMC kapena potassium CMC) chifukwa cha kusungunuka kwake kwakukulu komanso kukhazikika kwake m'madzi. Imapezeka m'mitundu yosiyanasiyana komanso m'magawo osiyanasiyana kuti igwirizane ndi zofunikira zosiyanasiyana pakukonza. Ponseponse, sodium CMC ndi chowonjezera chogwiritsidwa ntchito mosiyanasiyana komanso chogwiritsidwa ntchito kwambiri chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana.
