Gabaɗaya, methylcellulose yana da ƙarancin narkewa, musamman a cikin ruwan sanyi, kuma sau da yawa yana da mahimmanci a dumama ruwan don haɓaka narkewar sa. MC ɗin da aka narke yana da ɗanko mafi girma, wanda kuma muhimmin fasali ne a aikace-aikace da yawa na masana'antu.
Narkewar HPMC: Sabanin haka, HPMC yana da ingantaccen narkewar ruwa saboda shigar da hydroxypropyl. Yana iya narkewa da sauri a cikin ruwan sanyi, kuma saurin narkewarsa ya fi MC sauri. Saboda tasirin hydroxypropyl, narkewar HPMC ba wai kawai yana inganta a cikin ruwan sanyi ba, har ma da kwanciyar hankali da bayyana bayan narkewa suna inganta. Saboda haka, HPMC ya fi dacewa da aikace-aikacen da ke buƙatar narkewa cikin sauri.
3. Daidaiton zafi
Daidaiton zafin jiki na MC: Methylcellulose yana da ƙarancin kwanciyar hankali na zafi. Narkewa da dankonsa za su canza sosai a yanayin zafi mai yawa. Lokacin da zafin ya yi yawa, aikin MC yana iya shafar ruɓewar zafi cikin sauƙi, don haka amfani da shi a yanayin zafi mai yawa yana ƙarƙashin wasu ƙuntatawa.

Aikin HPMC yana da kwanciyar hankali a yanayin zafi mafi girma, don haka yana iya kiyaye sakamako mai kyau a cikin kewayon zafin jiki mai faɗi. Kwanciyar Hankalinsa yana ba da damar amfani da shi sosai a wasu yanayi masu zafi mai yawa (kamar sarrafa abinci da magunguna).
4. Halayen ɗanko
Danko na MC: Methyl cellulose yana da danko mafi girma a cikin ruwan da ke cikinsa kuma yawanci ana amfani da shi a yanayi inda ake buƙatar danko mai yawa, kamar masu kauri, masu canza sinadarai, da sauransu. Dankonsa yana da alaƙa da yawan sinadarin, zafin jiki da kuma matakin methylation. Babban matakin methylation zai ƙara danko na maganin.
Danko na HPMC: Danko na HPMC yawanci yana da ɗan ƙasa da na MC, amma saboda yawan narkewar ruwa da ingantaccen kwanciyar hankali na zafi, HPMC ya fi MC kyau a yanayi da yawa inda ake buƙatar ingantaccen sarrafa danko. Danko na HPMC yana shafar nauyin kwayoyin halitta, yawan ruwan da ke cikinsa da zafin narkewar sa.
5. Bambance-bambance a cikin filayen aikace-aikace
Amfani da MC: Ana amfani da Methyl cellulose sosai a gine-gine, shafa, sarrafa abinci, magani, kayan kwalliya da sauran fannoni. Musamman a fannin gini, wani abu ne da ake amfani da shi wajen ƙara kauri, inganta mannewa da inganta aikin gini. A masana'antar abinci, ana iya amfani da MC a matsayin mai kauri, mai narkewa da kuma mai daidaita jiki, kuma ana samunsa a cikin kayayyaki kamar jelly da ice cream.
Amfani da HPMC: Ana amfani da HPMC sosai a fannin magunguna, abinci, gini, kayan kwalliya da sauran masana'antu saboda kyawun narkewar sa da kuma kwanciyar hankali na zafi. A fannin magunguna, ana amfani da HPMC a matsayin maganin rage radadi ga magunguna, musamman a fannin shirye-shiryen baki, a matsayin maganin fim, mai kauri, wakili mai dorewa, da sauransu. A fannin abinci, ana amfani da HPMC a matsayin mai kauri da kuma mai tsarkake abinci ga abinci mai ƙarancin kalori, kuma ana amfani da shi sosai a cikin miyar salati, abinci mai daskarewa da sauran kayayyaki.
6. Kwatanta wasu kadarori
Bayyanar Gaskiya: Mafita ta HPMC yawanci tana da babban bayyananniyar hanya, don haka sun fi dacewa da aikace-aikacen da ke buƙatar bayyanar haske ko haske. Mafita ta MC yawanci ba ta da tsari.
Rashin lalacewa da aminci: Dukansu suna da kyakkyawan lalacewar halittu, muhalli na iya lalata su ta halitta a ƙarƙashin wasu yanayi, kuma ana ɗaukar su a matsayin masu aminci a aikace-aikace da yawa.
