Methylcellulose (MC) da Carboxymethyllulose (CMC) sune abubuwan da aka lalata guda biyu, ana amfani dasu a cikin abinci, maganin, gini, masana'antar sunadarai da sauran filayen. Duk da cewa duk ana gyara su ne masu emoliyuwa na halitta, akwai mahimman bambance-bambance a cikin tsarin sunadarai, na jiki da kayan sunadarai, da aikace-aikace.
1. Tsarin sunadarai da tsari na shiri
Methylcellulose ne ya samar da shi ta hanyar maido da selulose tare da methyl chloride (ko methanol) a ƙarƙashin yanayin alkaline. A yayin wannan tsari, wani ɓangare na ƙungiyoyin hydroxyl (-Oh) a cikin kwayoyin selulose an maye gurbinsu da ƙungiyoyi methoxy (-Och₃) don samar da methylcelse. Matsayi na maye (DS, yawan masu maye gurbin kowane yanki na glucose) na methylcelluloes na zahiri da sunadarai, kamar kayayyakin da danko.
Carboxymethylcelcelcellulose ana samar da shi ta hanyar maido da selulose tare da chloro sanetic acid a karkashin alkaline yanayin, kuma an maye gurbin ƙungiyar hyboxyl (-ch₂coohyl). Matsayi na canzawa da kuma digiri na polymerization (DP) na CMC yana shafar ƙima da danko a cikin ruwa. CMC yawanci yana wanzu a cikin nau'in gishiri na sodium, wanda ake kira ƙwayar sodium carboxymethylcelce (nacmc).
2. Kayan jiki da sunadarai
Sallasio: Methylcellulose ya narke a cikin ruwan sanyi, amma ya rasa Skillility da kuma samar da gel a cikin ruwan zafi. Wannan mai sauraro na zafi yana bawa damar amfani da shi azaman mai kauri da wakili a cikin sarrafa abinci. CMC mai narkewa a cikin ruwan sanyi da ruwan zafi, amma danko na maganin yana raguwa kamar yadda zafin jiki ya karu.
Danko: danko na duka biyun ya shafi matsayin canji da taro na bayani. Dalicin MC farko yana ƙaruwa sannan kuma yana raguwa kamar yadda zafin jiki ya karu, yayin da danko na CMC yana raguwa kamar yadda zafin jiki yake ƙaruwa. Wannan yana ba su damar nasu a aikace-aikacen masana'antu daban-daban.
Juyawar PH: CLC ta kasance mai tsayayyen yanayi akan babban yanki, musamman a ƙarƙashin yanayin alkaline, wanda ya sa ya shahara sosai a matsayin mai ƙwanƙwasa da magawa. MC yana da tabbaci a karkashin tsaka tsaki da yanayin alkaline, amma zai lalata cikin karfi acid ko alkalis.
3. Yankunan aikace-aikace
Masana'antar abinci: methylcellulose ana amfani dashi a cikin abinci a matsayin mai kauri, emulsifier da maimaitawa. Misali, zai iya kwaikwayon dandano da kayan kitse lokacin samar da abinci mai mai. Ana amfani da Carboxethylculo da yawa a cikin abubuwan sha, kayan da aka gasa da kayayyakin kiwo a matsayin mai kauri da mai kauri don hana rabuwa da ruwa da inganta dandano.
Ana amfani da masana'antu na magunguna: methylcellulose ana amfani dashi a cikin shirye-shiryen allunan kantin magunguna a matsayin mai ba da labari, kuma a matsayin mai kare mai kariya, kamar a cikin ido a matsayin madadin. Ana amfani da CMC sosai a cikin magani saboda kyakkyawan tarihinsa, kamar yadda shirye-shiryen kwayoyi masu saki da adheruves a cikin saukad da a ido saukad da.
Tsarin masana'antar sunadarai: MC an yi amfani da MC sosai a cikin kayan gini a matsayin mai kauri, wakilin ruwa da masarautar ciminti da gypsum. Zai iya inganta aikin aikin gini da ingancin kayan. Ana amfani da cmc sau da yawa a cikin laka a cikin ma'adinan ma'adinan mai, slurry a cikin buga bugawa da abin da ake girka, shafi na takarda, da sauransu.
4. Aminci da kare muhalli
Dukansu ana ɗaukarsu lafiya don amfani da aikace-aikacen abinci da magunguna, amma hanyoyinsu da kuma hanyoyin samarwa na iya samun tasiri daban-daban akan yanayin. Ana samun albarkatun ƙasa na MC da CMC daga Cel na halitta kuma sune tsirara, don haka suna yin abubuwa da kyau dangane da muhalli. Koyaya, tsarin samar da su na iya haɗawa da kayan shayarwa da reagents, wanda na iya samun wasu tasiri a kan yanayin.
5. Farashi da Bukatar Kasuwa
Saboda matakan samarwa daban-daban, samar da kudin methylcellullue yawanci yafi girma, don haka farashin kasarta kuma shine ya fi akwatin carboxyllulose. CMC gabaɗaya yana da buƙatun kasuwa mafi girma saboda yawan aikace-aikacen sa da ƙananan farashin kayayyaki.
Duk da cewa methylcellulose da carboxcellulose da carboxcellulose ne duka biyu na selulose na silfa, suna da mahimman bambance-bambance a tsari, kaddarorin, aikace-aikace da bukatun kasuwa. Ana amfani da methylcellulo galibi a cikin filayen abinci, magani da kayan gini saboda mai juyawa na narkewarsa na musamman da kuma ikon ƙarfafa. An yi amfani da Carboxymose na Carboxymose na Carboxymethyl sosai a cikin abinci, magani, petrochemical, tarko da sauran masana'antu saboda kyakkyawan sigari, daidaituwar gani da kuma gaba ɗaya daidaiton ph. Zaɓin sel ya dogara da takamaiman aikin aikace-aikacen da buƙatun.
