CMC (sodium carboxymethyl cellulose) da HPMC (hydroxypropyl methyl cellulose) su ne nau'ikan cellulose guda biyu da aka saba amfani da su, waɗanda ake amfani da su sosai a masana'antu daban-daban. Amma wanne ne ya fi kyau, ya dogara da takamaiman yanayin aikace-aikacen da buƙatun.
1. Chemical Properties
CMC wani fili ne mai narkewar ruwa na anionic wanda aka samu ta hanyar magance cellulose na halitta tare da sodium chloroacetate a ƙarƙashin yanayin alkaline. An gabatar da ƙungiyoyin Carboxymethyl a cikin sarkar kwayoyin halitta, wanda ke sa ya sami ingantaccen ruwa mai narkewa da kauri.
HPMC shine ether cellulose maras ionic wanda aka samu ta hanyar amsawa da amsa cellulose tare da methyl chloride da propylene oxide. Ƙungiyoyin methoxy da hydroxypropoxy a cikin tsarin kwayoyin halitta na HPMC suna ba shi kyakkyawan kauri, kwanciyar hankali da riƙewar ruwa, da kuma kyawawan abubuwan gel na thermal.
2. Filin aikace-aikace
Masana'antar abinci: Ana amfani da CMC sau da yawa a cikin abinci azaman mai kauri, stabilizer, wakili mai dakatarwa da emulsifier, da sauransu, kuma ana samun su a cikin yogurt, ice cream, jelly, abubuwan sha da kayan gasa. Zai iya inganta yanayin abinci kuma ya tsawaita rayuwar shiryayye. Kodayake ana amfani da HPMC a masana'antar abinci, galibi ana amfani da shi azaman ƙari ga fiber na abin da ake ci, musamman a wasu samfuran marasa alkama.

Kaddarorin sa marasa ionic da kyakkyawan yanayin rayuwa suna ba shi fa'idodi na musamman a cikin tsarin isar da magunguna. Hakanan ana amfani da CMC a cikin masana'antar harhada magunguna, amma ƙari azaman mai kauri da mannewa ga magunguna.
Masana'antar gine-gine da sutura: Ana amfani da HPMC sosai a cikin kayan gini, musamman a busassun turmi, gypsum, da foda, saboda kyakkyawan riƙewar ruwa, kauri da kaddarorin hana zamewa. Hakanan CMC yana da wasu aikace-aikace a cikin masana'antar sutura, amma an fi amfani dashi azaman mai kauri don suturar tushen ruwa.
Kayan shafawa da kulawar mutum: Ana amfani da HPMC sau da yawa a cikin kayan kwalliya, musamman a cikin kayan shafawa, creams, shampoos da goge goge, azaman mai kauri, emulsion stabilizer da moisturizer. Hakanan ana amfani da CMC a aikace-aikace iri ɗaya, amma tasirin sa mai ɗanɗano ba shi da kyau kamar HPMC.
3. Halayen ayyuka
Ruwa mai narkewa: Ana iya narkar da CMC da kyau a cikin ruwan sanyi da ruwan zafi, yayin da HPMC ke saurin narkewa a cikin ruwan sanyi, amma ba a narkewa a cikin ruwan zafi kuma yana da gelation thermal. Don haka, HPMC ya fi dacewa da samfuran da ke buƙatar kaddarorin gelation na thermal a wasu aikace-aikace, kamar allunan da aka sarrafa-saki a cikin magani.
Ikon danko: CMC yana da ɗan ɗanko kaɗan kuma yana da sauƙin sarrafawa, yayin da HPMC yana da kewayon ɗanko mai faɗi kuma ya fi dacewa. HPMC na iya samar da danko mafi girma kuma ya kasance barga a yanayin zafi daban-daban, wanda ke sa ya fi fa'ida a aikace-aikacen da ke buƙatar madaidaicin kulawar danko.
Kwanciyar hankali: HPMC yana da mafi kyawun kwanciyar hankali fiye da CMC. Yana nuna kwanciyar hankali mai kyau a cikin yanayin acidic ko alkaline, yayin da CMC na iya raguwa a cikin karfi acid ko tushe mai karfi.
4. Farashin da farashi
Gabaɗaya, CMC yana da ɗan arha kuma ya dace da manyan aikace-aikacen masana'antu, yayin da HPMC yana da ɗan tsada saboda tsarin samar da sarkar sa da tsada. CMC na iya zama mafi kyawu a yanayi inda ake buƙatar adadi mai yawa kuma farashi yana da mahimmanci. Koyaya, a wasu fagagen da ke da manyan buƙatun aiki, kamar magani da kayan kwalliya masu tsayi, HPMC har yanzu ana amfani da ita sosai saboda fa'idodin aikinta na musamman duk da tsadar sa.
5. Kariyar muhalli da aminci
Dukansu CMC da HPMC suna da kyakkyawan yanayin halitta da kariyar muhalli, kuma suna da ɗan tasiri akan muhalli yayin amfani. Dukansu ana ɗaukar lafiyayyen abinci da ƙari na ƙwayoyi, kuma ana iya amfani da su cikin aminci a cikin samfuran daban-daban bayan tsananin kulawa da takaddun shaida.
CMC da HPMC suna da nasu fa'ida da rashin amfani, kuma ba zai yiwu a ce kawai wanne ya fi kyau ba. Don aikace-aikacen da ke buƙatar ƙarancin farashi, samarwa mai girma, kamar masana'antar abinci na gabaɗaya da buƙatun kauri mai sauƙi, CMC zaɓi ne mai tsada. A cikin filayen da manyan buƙatun aiki, kamar tsarin sakin sarrafa magunguna, kayan gini na ƙarshe da kayan kwalliya na zamani, HPMC na iya zama mafi dacewa saboda kyakkyawan aikin sa. Sabili da haka, zaɓin abin da aka samo asali na cellulose ya dogara da ƙayyadaddun buƙatun aikace-aikacen, bukatun aiki da la'akari da farashi.
