A cikin masana'antar abinci, ana amfani da methylcellulose sosai a cikin sutura ko tsarin shirya fim, musamman a cikin sabbin kayan adana kayan marmari, kayan lambu da sauran abinci. Ta hanyar samar da fim na bakin ciki, methylcellulose yana jinkirta asarar danshi kuma yana kare abinci daga yanayin waje.
5. Tsayawa da emulsification
Methylcellulose na iya samar da babban danko bayani lokacin da aka narkar da shi a cikin ruwa, wanda yana da ƙarfafawa da sakamako masu tasiri. Wannan kadarar tana da mahimmanci musamman a masana'antu irin su sutura, fenti, kayan kwalliya da shirye-shiryen magunguna. A cikin fenti da fenti, methylcellulose na iya tabbatar da tarwatsawar pigments, hana daidaitawa, da inganta haske da daidaituwa na sutura; a cikin kayan kwaskwarima, methylcellulose yana aiki azaman emulsifier don daidaita tsarin gauraye na ruwa da mai kuma ya hana Stratification faruwa.
A cikin shirye-shiryen magunguna, ana amfani da methylcellulose akai-akai don kauri da daidaita shirye-shiryen ruwa na baka kuma azaman mai ɗaukar magunguna. Dankowar sa da abubuwan samar da fina-finai na iya taimakawa a saki miyagun ƙwayoyi a hankali, tsawaita lokacin tasirin miyagun ƙwayoyi, da haɓaka haɓakar ƙwayar cuta.
6. Thermal gelling Properties
Wani muhimmin abu na jiki na methylcellulose shine halayen gelling na musamman na thermal, inda ya juya zuwa gel lokacin zafi. Wannan halayyar ta sa ba za a iya maye gurbinsa ba a cikin wasu ƙirar masana'antu na musamman. Misali, a cikin masana'antar abinci, ana amfani da methylcellulose don sarrafa abinci mara nauyi. Gel da aka kafa bayan dumama yana da dandano mai kama da mai, yana barin abinci maras nauyi don kula da dandano mai kyau da laushi. A cikin masana'antar gine-gine, wannan kayan gelling na thermal yana inganta dorewa da kwanciyar hankali na kayan gini a cikin yanayin zafi mai zafi.
7. Biocompatibility da muhalli abokantaka
Methylcellulose, a matsayin fili da aka samu ta halitta, yana da kyakkyawar dacewa da yanayin muhalli. Wannan ya sa ya ƙara shahara a cikin ƙirar masana'antu na zamani, musamman a wuraren da ke da mafi girman buƙatun kare muhalli, kamar gine-ginen kore, rufin muhalli da kayan marufi masu lalacewa. Methylcellulose na iya lalacewa ta dabi'a, yana rage nauyin muhalli da kuma dacewa da yanayin masana'antu na ci gaba mai dorewa.
8. Inganta aikin sarrafawa
A cikin samar da masana'antu, methylcellulose na iya inganta ingantaccen aiki. Alal misali, a cikin kayan gini, methylcellulose na iya inganta yawan ruwa da ruwa na kayan aiki, ta yadda za a inganta sauƙi da inganci na ginin; a cikin kayan shafawa da shirye-shiryen magunguna, methylcellulose na iya inganta kwanciyar hankali na dabaru da rage hazo. da delamination, don haka tsawaita rayuwar samfurin. Waɗannan kaddarorin suna ba da damar methylcellulose don haɓaka haɓakar samarwa sosai yayin haɓaka ƙirar masana'antu.
A matsayin ƙari na multifunctional, ana amfani da methylcellulose a yawancin masana'antu irin su gine-gine, abinci, magani, kayan shafawa, sutura, da dai sauransu saboda yawancin kaddarorinsa irin su thickening, riƙewar ruwa, haɗin gwiwa, samar da fim, ƙarfafawa, emulsification da gelling thermal. yana taka muhimmiyar rawa a fagen. Ba wai kawai zai iya haɓaka kaddarorin jiki na ƙirar masana'antu ba, amma kuma inganta haɓakar samarwa da biyan buƙatun masana'antu iri-iri. A lokaci guda kuma, haɓakar haɓakawa da abokantakar muhalli na methylcellulose kuma sun sa ya zama kyakkyawan abu wanda ya dace da buƙatun ci gaba mai dorewa. Ta hanyar yin amfani da methylcellulose a hankali a cikin ƙirar masana'antu, ba zai iya inganta ingancin samfurin kawai ba, amma kuma yana inganta ci gaba da haɓaka fasahar masana'antu.
