Carboxymethylcellulose (CMC) da methylcellulose (MC) duka abubuwan da aka samo asali ne na cellulose, polymer na halitta da ake samu a bangon tantanin halitta.Waɗannan abubuwan haɓaka suna samun amfani mai yawa a masana'antu daban-daban saboda keɓaɓɓen kaddarorinsu.Duk da raba kamanceceniya, CMC da MC suna da bambance-bambance daban-daban a cikin tsarin sinadarai, kaddarorinsu, aikace-aikace, da amfanin masana'antu.
1. Tsarin Kemikal:
Carboxymethylcellulose (CMC):
CMC an haɗa shi ta hanyar etherification na cellulose tare da acid chloroacetic, wanda ya haifar da maye gurbin kungiyoyin hydroxyl (-OH) akan kashin baya na cellulose tare da ƙungiyoyin carboxymethyl (-CH2COOH).
Matsayin maye gurbin (DS) a cikin CMC yana nufin matsakaicin adadin ƙungiyoyin carboxymethyl a kowace naúrar glucose a cikin sarkar cellulose.Wannan siga yana ƙayyade kaddarorin CMC, gami da solubility, danko, da halayen rheological.
Methylcellulose (MC):
Ana samar da MC ta hanyar maye gurbin ƙungiyoyin hydroxyl a cikin cellulose tare da ƙungiyoyin methyl (-CH3) ta hanyar etherification.
Hakazalika da CMC, kaddarorin MC suna tasiri ta hanyar matakin maye gurbin, wanda ke ƙayyade girman methylation tare da sarkar cellulose.
2. Solubility:
Carboxymethylcellulose (CMC):
CMC yana narkewa a cikin ruwa kuma yana samar da madaidaiciya, mafita mai danko.
Solubility yana dogara da pH, tare da mafi girma solubility a cikin yanayin alkaline.
Methylcellulose (MC):
Hakanan MC yana narkewa cikin ruwa, amma narkewar sa ya dogara da yanayin zafi.
Lokacin da aka narkar da cikin ruwan sanyi, MC yana samar da gel, wanda zai sake narkewa akan dumama.Wannan dukiya ta sa ya dace da aikace-aikacen da ke buƙatar gelation mai sarrafawa.
3. Dangantaka:
CMC:
Yana nuna babban danko a cikin maganin ruwa, yana ba da gudummawa ga kaddarorin sa.
Ana iya canza dankowar sa ta hanyar daidaita abubuwa kamar maida hankali, matakin maye gurbin, da pH.
MC:
Yana nuna halin danko mai kama da CMC amma gabaɗaya ba shi da ɗanko.
Hakanan ana iya sarrafa dankowar hanyoyin MC ta hanyar canza sigogi kamar zafin jiki da maida hankali.
4. Samuwar Fim:
CMC:
Yana samar da fina-finai a sarari, masu sassauƙa lokacin da aka jefa su daga mafita mai ruwa.
Wadannan fina-finai suna samun aikace-aikace a cikin masana'antu kamar kayan abinci da magunguna.
MC:
Hakanan yana iya ƙirƙirar fina-finai amma yana da ƙaranci idan aka kwatanta da fina-finan CMC.
5. Masana'antar Abinci:
CMC:
Ana amfani da shi sosai azaman stabilizer, thickener, da emulsifier a cikin samfuran abinci kamar ice cream, miya, da riguna.
Ƙarfinsa don gyara nau'i da jin daɗin kayan abinci yana sa ya zama mai daraja a cikin tsarin abinci.
MC:
Ana amfani dashi don dalilai iri ɗaya kamar CMC a cikin samfuran abinci, musamman a aikace-aikacen da ke buƙatar samuwar gel da daidaitawa.
6.Magunguna:
CMC:
An yi amfani da shi a cikin ƙirar magunguna azaman ɗaure, rarrabuwa, da gyare-gyaren danko a masana'antar kwamfutar hannu.
Har ila yau, ana amfani da shi a cikin kayan shafawa kamar creams da gels saboda halayen rheological.
MC:
Yawanci ana amfani dashi azaman mai kauri da gelling a cikin magunguna, musamman a cikin magungunan ruwa na baka da maganin ido.
7.Kayayyakin Kulawa na Kansu:
CMC:
Ana samun su a cikin abubuwan kulawa daban-daban kamar man goge baki, shamfu, da magarya azaman abin ƙarfafawa da mai kauri.
MC:
An yi amfani da shi a cikin aikace-aikace iri ɗaya kamar CMC, yana ba da gudummawa ga rubutu da kwanciyar hankali na tsarin kulawa na sirri.
8. Aikace-aikacen masana'antu:
CMC:
Aiki a cikin masana'antu kamar su yadi, takarda, da yumbu don ikonsa na aiki azaman ɗaure, mai gyara rheology, da wakili mai riƙe ruwa.
MC:
Ana samun amfani da shi a cikin kayan gini, fenti, da mannewa saboda kaurin sa da ɗaure shi.
yayin da carboxymethylcellulose (CMC) da methylcellulose (MC) duka biyun cellulose ne tare da aikace-aikacen masana'antu daban-daban, suna nuna bambance-bambance a cikin tsarin sinadarai, halayen solubility, bayanan danko, da aikace-aikace.Fahimtar waɗannan bambance-bambancen yana da mahimmanci don zaɓar abin da ya dace don takamaiman amfani a masana'antu daban-daban, kama daga abinci da magunguna zuwa kulawa na sirri da aikace-aikacen masana'antu.Ko ana buƙatar mai kauri mai saurin pH kamar CMC a cikin samfuran abinci ko wakilin gelling mai ɗaukar zafin jiki kamar MC a cikin ƙirar magunguna, kowane abin da aka samo asali yana ba da fa'idodi na musamman waɗanda ke dacewa da takamaiman buƙatu a sassa daban-daban.
