Ọdịiche dị n'etiti CMC na MHEC
Carboxymethylcellulose (CMC) na Methyl hydroxyethyl cellulose (MHEC) bụ ụdị abụọ a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche. Ha na-ekerịta ụfọdụ myirịta na nhazi kemịkalụ ha na akụrụngwa anụ ahụ, mana ha nwekwara ụfọdụ isi dị iche iche na-eme ka ha dabara maka ngwa dị iche iche. N'edemede a, anyị ga-enyocha ọdịiche dị n'etiti CMC na MHEC.
Ọdịdị Chemical
Ma CMC na MHEC bụ ihe nrụpụta cellulose bụ polymers soluble mmiri. A na-enweta CMC site na cellulose site n'imeghachi ya na chloroacetic acid iji webata otu carboxymethyl, ebe MHEC sitere na cellulose site na ime ya na ethylene oxide na methyl chloride iji webata methyl na hydroxyethyl otu.
Solubility
Otu n'ime isi ihe dị iche n'etiti CMC na MHEC bụ solubility ha na mmiri. CMC na-agbaze nke ukwuu na mmiri ma nwee ike ịmepụta ngwọta doro anya, viscous ọbụna na obere mkpokọta. N'ụzọ dị iche, MHEC bụ obere soluble na mmiri karịa CMC ma na-achọkarị iji ihe mgbaze, dị ka ethanol ma ọ bụ mmanya isopropyl, gbazee kpamkpam.
Viscosity
Ma CMC na MHEC nwere ike mee ka ihe ngwọta na-eme ka mmiri sie ike ma nwekwuo viscosity. Otú ọ dị, CMC nwere viscosity dị elu karịa MHEC, ọ pụkwara ịmepụta ihe na-eme ka gel-dị ka mgbe ọ gbazere na mmiri. Nke a na-eme ka CMC dị mma maka ojiji na ngwa ebe achọrọ ịgbari ma ọ bụ gelling, dị ka n'ụlọ ọrụ nri maka ịme sauces na uwe. MHEC, n'aka nke ọzọ, nwere viscosity dị ala karịa CMC ma na-ejikarị eme ihe dị ka thickener ma ọ bụ rheology modifier na ngwa ebe a chọrọ obere viscous ngwọta.
pH kwụsie ike
CMC na-akwụsikarị ike karịa oke pH karịa MHEC. CMC kwụsiri ike na gburugburu acidic na alkaline, nke na-eme ka ọ dị mma maka iji ya na ụlọ ọrụ nri, ebe ụkpụrụ pH nwere ike ịdị iche iche. N'ụzọ dị iche, MHEC kwụsiri ike na obere acidic na gburugburu pH na-anọpụ iche ma nwee ike ịkụda na ụkpụrụ pH dị elu.
Okpomọkụ kwụsie ike
Ma CMC na MHEC kwụsiri ike karịa oke okpomọkụ, mana enwere ọdịiche dị na nkwụsi ike okpomọkụ ha. CMC kwụsiri ike karịa MHEC ma nwee ike idowe akụrụngwa ya na okpomọkụ dị elu. Nke a na-eme ka CMC dị mma maka ojiji na ngwa ebe okpomọkụ dị elu na-etinye aka, dị ka n'ichepụta ngwaahịa esi nri. MHEC, n'aka nke ọzọ, nwere nkwụsi ike dị ala karịa CMC ma nwee ike ịkụda na okpomọkụ dị elu.
Ngwa
A na-eji ma CMC na MHEC mee ihe n'ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche. A na-ejikarị CMC eme ihe dị ka thickener, stabilizer, na emulsifier na ụlọ ọrụ nri maka ngwaahịa dị ka ice cream, sauces, na uwe. A na-ejikwa ya na ụlọ ọrụ na-emepụta ọgwụ dị ka onye na-ekekọta, ihe na-agbaji, na nkwụsịtụ. A na-ejikarị MHEC eme ihe dị ka ihe ngbochi, njide, na rheology modifier na ụlọ ọrụ ihe owuwu maka ngwaahịa dị ka agba, mkpuchi, na nrapado. A na-ejikwa ya na ụlọ ọrụ na-emepụta ọgwụ dị ka ihe na-ekekọta, ihe na-agbasa, na onye na-ahapụ ya.
N'ikpeazụ, CMC na MHEC bụ mkpụrụ ndụ cellulose abụọ na-ekerịta ụfọdụ myirịta na usoro kemịkal ha na ihe anụ ahụ ha mana ha nwere ọdịiche dị iche na solubility ha, viscosity, pH nkwụsi ike, nkwụsi ike okpomọkụ, na ngwa.
