A cikin masana'antar sinadarai, CMC (Carboxymethyl Cellulose Sodium) kuma ana kiransa CMC. CMC shine muhimmin tushen cellulose wanda aka samu ta hanyar sinadarai na gyaggyarawa na halitta cellulose. Musamman, tsarin kwayoyin halitta na CMC shine cewa ana shigar da ƙungiyoyin carboxymethyl a cikin kwayar halitta ta cellulose, wanda ke ba shi sabbin abubuwa masu yawa na jiki da sinadarai, don haka ana amfani dashi sosai a cikin sinadarai, abinci, magani da sauran masana'antu.
1. Tsarin sunadarai da kaddarorin CMC
CMC wani fili ne na ether cellulose da aka samu ta hanyar amsawar cellulose da chloroacetic acid, kuma ainihin tsarin sa shine β-1,4-glucose zobe. Ba kamar cellulose na halitta ba, ana gabatar da ƙungiyoyin carboxymethyl a cikin tsarin kwayoyin halitta na CMC, wanda ke ba shi damar samar da maganin colloidal danko a cikin ruwa. Za'a iya daidaita nauyin kwayoyin CMC bisa ga matakin amsawa, kuma CMCs na nau'i daban-daban na kwayoyin halitta suna nuna nau'i daban-daban da kuma danko a aikace-aikace. Solubility da danko na CMC suna shafar matakin maye gurbin (wato, adadin masu maye a kan kwayoyin cellulose). CMC tare da babban mataki na canji yawanci yana da mafi girman solubility da danko. CMC yana da babban kwanciyar hankali na sinadarai, yana da takamaiman haƙuri ga mahallin acid da alkali, ba mai guba ba ne kuma mara lahani, kuma ya sadu da kariyar muhalli da ka'idodin kiwon lafiya.
2. Tsarin samar da CMC
Tsarin samarwa na CMC ya ƙunshi matakai uku: alkalization, etherification da bayan jiyya.
Alkalization: Cellulose (yawanci daga kayan halitta irin su auduga da ɓangaren litattafan almara) ana bi da su tare da sodium hydroxide don haɓaka aikin hydroxyl na cellulose, wanda ya dace da halayen da suka biyo baya.
Etherification: Ana ƙara sodium chloroacetate zuwa cellulose alkalized, kuma ana gabatar da ƙungiyoyin carboxymethyl ta hanyar mayar da cellulose zuwa carboxymethyl cellulose.
Bayan-jiyya: CMC da aka samar ta hanyar amsawa ba ta daɗe, tacewa, bushewa da niƙa don a ƙarshe samun samfuran ƙayyadaddun bayanai daban-daban. Matsayin maye gurbin da nauyin kwayoyin halitta na samfurin za'a iya daidaita shi ta hanyar sarrafa yanayin amsawa, ƙaddamar da albarkatun ƙasa da lokacin amsawa, don samun samfuran CMC tare da viscosities daban-daban da kaddarorin solubility.
3. Ayyukan ayyuka na CMC
A matsayin mai ingantacciyar kauri, stabilizer, tsohon fim da mannewa, CMC yana da halaye masu zuwa:
Kyakkyawan solubility na ruwa: CMC yana da sauƙin narkewa a cikin ruwa kuma yana iya samar da maganin colloidal na gaskiya, kuma tsarin rushewa yana da sauƙi da sauƙi don aiki.
Strong thickening sakamako: CMC iya muhimmanci ƙara danko na bayani a wani m taro, wanda ya sa shi da high aikace-aikace darajar a lokuta da dama inda thickening effects ake bukata.
Kwanciyar hankali: CMC yana da babban haƙuri ga acid, alkali, haske, zafi, da dai sauransu, kuma yana da kwanciyar hankali mai kyau.
Amintacce kuma mara guba: CMC ana amfani dashi sosai a abinci, magunguna da sauran masana'antu. Yana da aminci kuma mara guba kuma ya dace da kayan tuntuɓar abinci kai tsaye ko kaikaice.
4. Filin aikace-aikacen CMC
Masana'antar abinci: Ana amfani da CMC sosai azaman mai kauri, emulsifier, stabilizer, da sauransu a cikin masana'antar abinci. Ana iya amfani da shi a cikin ice cream, jam, condiments, abubuwan sha, kayan kiwo, da dai sauransu don inganta ingantaccen rubutu, dandano da kwanciyar hankali na abinci. Misali, CMC a matsayin mai kauri a cikin ice cream zai iya hana samuwar lu'ulu'u na kankara yadda ya kamata kuma ya sa dandanon ice cream ya yi laushi.
Masana'antar harhada magunguna: A cikin fannin harhada magunguna, ana iya amfani da CMC azaman manne don allunan, matrix don man shafawa, da mai kauri ga wasu magungunan ruwa. CMC kuma yana da wasu mannewa da abubuwan ƙirƙirar fim, waɗanda zasu iya haɓaka tasirin sakin da aka sarrafa na kwayoyi da haɓaka kwanciyar hankali da ƙimar ɗaukar kwayoyi.
Masana'antar sinadarai ta yau da kullun: A cikin kayan kwalliya da samfuran kulawa na mutum, ana amfani da CMC sosai a cikin kayan shafawa, creams, shampoos da sauran samfuran azaman mai kauri da daidaitawa. Kyakkyawan narkewar ruwa na CMC da abubuwan samar da fim suna ba shi damar daidaita tsarin kayan kwalliya da haɓaka laushin samfur.
Masana'antar man fetur: CMC tana taka rawar mai kauri da tacewa wajen hako ruwa, karyewar ruwa da slurry na siminti, yadda ya kamata yana rage haɗarin ruwa da toshewa yayin hakowa, da haɓaka haɓaka hakowa da aminci.
Masana'antar masana'anta da masana'anta: CMC za a iya amfani da shi azaman wakili na sikelin sikelin, kayan aikin gamawa da ƙari na takarda a cikin filayen yadi da takarda, wanda zai iya inganta ƙarfin yarn da haɓaka juriya na ruwa da ƙarfi na takarda.
5. Bukatar kasuwa da ci gaban ci gaban CMC
Tare da saurin haɓakar tattalin arzikin duniya da ci gaban fasaha, buƙatun kasuwa na CMC yana haɓaka. Musamman a cikin masana'antun abinci da magunguna, yayin da masu amfani suka fi mai da hankali kan lafiya da aminci, kauri na halitta da mara lahani CMC a hankali ya maye gurbin wasu sinadarai na roba. A nan gaba, ana sa ran buƙatun kasuwar CMC za ta ci gaba da faɗaɗa, musamman a cikin hasashen aikace-aikacen masu kaurin abinci, ruwan hakowa, dillalan sakin magunguna, da sauransu.
Tunda tushen albarkatun ƙasa na CMC shine mafi yawan cellulose na halitta, tsarin samarwa yana da ƙarancin muhalli. Domin samun bunkasuwar ci gaban masana'antar sinadarai masu kore, tsarin samar da CMC shi ma yana ci gaba da inganta, kamar rage fitar da gurbatacciyar iska a harkar samar da kayayyaki, inganta amfani da albarkatu, da dai sauransu, da kokarin ganin samar da CMC ya cimma burin da aka sa a gaba. na ci gaba mai dorewa.
A matsayin muhimmin abin da aka samu na cellulose, sodium carboxymethyl cellulose (CMC) an yi amfani dashi sosai a masana'antu da yawa kamar sinadarai, abinci, magani, sinadarai na yau da kullum, man fetur, yadi da takarda saboda rashin ruwa na musamman, kauri da kwanciyar hankali. Tare da ci gaban fasaha da karuwar buƙatun kasuwa, tsarin samarwa da filayen aikace-aikacen CMC suna ci gaba da haɓakawa, kuma yana da muhimmiyar damar ci gaba a fannonin masana'antar sinadarai na kore da aikace-aikacen manyan ayyuka a nan gaba.
