Menene bambanci tsakanin CMC da MC?

CMC da MC duka abubuwan da aka samo asali ne na cellulose waɗanda galibi ana amfani da su azaman masu kauri, masu ɗaurewa, da masu daidaitawa a aikace-aikace daban-daban, gami da masana'antar abinci, magunguna, da masana'antar kulawa ta sirri. Koyaya, akwai wasu bambance-bambance tsakanin su biyun da yakamata a lura dasu.

CMC, ko Carboxymethyl Cellulose, shine polymer mai narkewa da ruwa wanda aka samo daga cellulose. An ƙirƙira shi ta hanyar amsawar cellulose tare da sodium chloroacetate da canza wasu ƙungiyoyin hydroxyl akan cellulose zuwa ƙungiyoyin carboxymethyl. Ana amfani da CMC sosai a cikin samfuran abinci, kamar kayan gasa, kayan kiwo, da miya, da kuma a cikin samfuran kulawa na sirri da magunguna.

MC, ko Methyl Cellulose, shi ma polymer ne mai narkewa da ruwa wanda aka samo daga cellulose. An ƙirƙira shi ta hanyar amsawar cellulose tare da methyl chloride da kuma canza wasu ƙungiyoyin hydroxyl akan cellulose zuwa ƙungiyoyin methyl ether. Ana amfani da MC azaman mai kauri, ɗaure, da emulsifier a aikace-aikace daban-daban, gami da samfuran abinci, kamar miya, riguna, da daskararrun kayan zaki, kuma a cikin magunguna da samfuran kulawa na sirri.

Babban bambanci tsakanin CMC da MC shine halayen solubility. CMC ya fi saurin narkewa a cikin ruwa fiye da MC, kuma yana iya samar da bayani mai haske, mai ɗanɗano a ƙananan ƙira. MC, a gefe guda, yawanci yana buƙatar mafi girma taro da/ko dumama don narkar da cikakke cikin ruwa, kuma mafitansa na iya zama mafi duhu ko gajimare.

Wani bambanci shine halayen su a cikin yanayi daban-daban na pH. CMC ya fi kwanciyar hankali a cikin yanayin acidic kuma yana iya jure wa faɗuwar pH fiye da MC, wanda zai iya rushewa kuma ya rasa kaddarorin sa na kauri a cikin yanayin acidic.

Dukansu CMC da MC sune abubuwan haɓakar cellulose masu yawa waɗanda ke da kaddarorin amfani da yawa don aikace-aikace daban-daban. Zaɓin wanda za a yi amfani da shi zai dogara ne akan takamaiman buƙatun aikace-aikacen da halayen aikin da ake so.
