9. Uru na ọghọm nke MHEC

Uru:

Ntughari: MHEC nwere otutu oru dika ndi nkpu, njide mmiri, nkwusioru, emulsification, wdg, ma nwee otutu ngwa.

Enyi na gburugburu ebe obibi: MHEC bụ ihe na-emebi emebi nwere obere mmetọ gburugburu ebe obibi.

Nkwụsi ike siri ike: Ọ na-egosi nkwụsi ike dị mma n'okpuru pH dị iche iche na ọnọdụ okpomọkụ.

Ihe ọghọm:

Ọnụ ego dị elu: E jiri ya tụnyere ụfọdụ ihe ọkụkụ ọdịnala, ọnụ ahịa mmepụta nke MHEC dị elu.

Ndakọrịta na ụfọdụ kemịkalụ: N'ụdị ụfọdụ, MHEC nwere ike ịnwe okwu ndakọrịta na ụfọdụ kemịkalụ.

N'ihi ọmarịcha anụ ahụ na kemịkal ya, a na-eji methyl hydroxyethyl cellulose (MHEC) eme ihe n'ọtụtụ ụlọ ọrụ dịka ihe owuwu, mkpuchi, mmanụ ala, nri, ọgwụ na imepụta akwụkwọ. Dị ka onye na-agba agba, onye na-ejide mmiri, ihe nkedo na stabilizer, ọ na-enye nkwado ọrụ isi maka ngwaahịa na usoro na mpaghara dị iche iche. Otú ọ dị, na ngwa ndị bara uru, a ghaghị ịtụle nkwekọ ya na ihe ndị ọzọ na ihe ndị na-eri ego. N'ọdịnihu, na ọganihu nke nkà na ụzụ na mgbanwe nke ahịa ahịa, mpaghara ngwa nke MHEC nwere ike gbasaa ọzọ.
