Dịka ọmụmaatụ, na ihe ọṅụṅụ oyi, ngwaahịa mmiri ara ehi na condiments, MHEC nwere ike gbanwee viscosity nke nri, meziwanye uto ya na ọdịdị ya, ma mee ka ngwaahịa ahụ dịkwuo mma.
6. Ụlọ ọrụ akwa na akwụkwọ
N'ime ụlọ ọrụ textile, enwere ike iji MHEC dị ka onye na-agba ume na stabilizer maka pulp textile iji nyere aka melite ire ụtọ na nkwụsi ike nke textiles. N'ime ụlọ ọrụ akwụkwọ, MHEC na-ejikarị eme ka ike na ịdị nro nke akwụkwọ dịkwuo mma ma melite arụmọrụ mbipụta akwụkwọ.
7. Ogige ndị ọzọ
A na-ejikwa MHEC na kemịkalụ mmanụ, ọgwụ pesticides, ngwa eletrọnịkị na mpaghara ndị ọzọ. Dịka ọmụmaatụ, na kemịkalụ mmanụ, MHEC na-eji dị ka onye na-eku ume na mmiri mmiri na-ebelata mmiri mmiri iji nyere aka ịchịkwa viscosity na njirimara rheological nke mmiri mmiri. N'ime usoro ọgwụgwọ pesticide, a na-eji MHEC mee ihe dị ka ihe na-ekpo ọkụ ma na-ekesa iji nyere aka kesaa ihe ndị na-egbu ihe na-egbu egbu ma mee ka ọ dị ogologo oge.
Methyl hydroxyethyl cellulose (MHEC) bụ ihe nrụpụta cellulose nwere ọmarịcha arụmọrụ. N'ihi ịdị mma ya nke ọma, njide mmiri, imepụta ihe nkiri na nkwụsi ike, ejirila ya mee ihe n'ọtụtụ ụlọ ọrụ dịka ihe owuwu ụlọ, mkpuchi, ihe ịchọ mma, na ọgwụ. Site na imeziwanye arụmọrụ na ịdị mma nke ngwaahịa, MHEC na-arụ ọrụ dị mkpa na mmepụta na ntinye nke ụlọ ọrụ dị iche iche.
