Methylcellulose (MC) bụ cellulose emezigharịrị kemịkalụ, polymer soluble mmiri nke enwetara site na akụkụ methylation nke cellulose. N'ihi njirimara physicochemical pụrụ iche ya na biocompatibility, methylcellulose na-ejikarị eme ihe na nri, ọgwụ, ihe ụlọ, ihe ịchọ mma na ubi ndị ọzọ.
1. Mmiri solubility na gel-akpụ ike
Methylcellulose nwere ezigbo mmiri solubility ma nwee ike ịmepụta ngwọta colloidal transperent na mmiri oyi. Mgbe okpomọkụ na-ebili, ngwọta a ga-enweta gelation thermal iji mepụta gel siri ike. Ngwongwo a na-eme methylcellulose n'ọtụtụ ebe na ice cream, ude, jelii na ngwaahịa ndị ọzọ dị ka thickener, stabilizer na emulsifier na ụlọ ọrụ nri. Na mgbakwunye, na nkwadebe ọgwụ, enwere ike iji ya chịkwaa ọnụego ntọhapụ nke ọgwụ ma melite akụrụngwa anụ ahụ nke mbadamba.
2. Usoro viscosity
Enwere ike imezi viscosity nke ngwọta methylcellulose site n'ịgbanwe nhazi ya, ịdị arọ molecular na okpomọkụ. Ngwongwo a na-eme methylcellulose ka ọ bụrụ ezigbo ihe na-eme ka ọ bụrụ ihe na-edozi ahụ, nke a na-ejikarị eme ihe na mmepụta ihe ụlọ dị ka ciment na gypsum iji mee ka arụ ọrụ ya na ịdịte aka. N'otu oge ahụ, a pụkwara iji ya dị ka onye na-ahụ maka nchịkwa rheology maka ibipụta inks na mkpuchi iji melite arụmọrụ mkpuchi na nkwụsi ike nke ngwaahịa ahụ.
3. Ihe nkiri na-emepụta ihe
Methylcellulose nwere ikike imepụta ihe nkiri mara mma ma nwee ike mepụta otu ihe nkiri na-enweghị atụ nke nwere ike arụ ọrụ. Ihe nkiri a nwere ezigbo ikuku ikuku na njigide mmiri, a na-ejikwa ya na ihe nkiri nri nri, ihe mkpuchi ọgwụ, na ihe mkpuchi ihu na ihe ịchọ mma. Ihe ndị na-emepụta ihe nkiri ya abụghị nanị na-echebe ngwaahịa ahụ site na mmetọ nke mpụga, kamakwa na-achịkwa mgbanwe nke mmiri na gas nke ọma.
4. Biocompatibility na nchekwa
Dị ka cellulose gbanwetụrụ site na isi mmalite, methylcellulose nwere ezigbo bioocompatibility na nchekwa, ọ naghị ebutekarị mmeghachi omume nfụkasị ma ọ bụ mmetụta nsị. Ya mere, na nkwadebe ọgwụ, a na-eji methylcellulose mee ihe n'ọtụtụ ebe na mmepụta nke mbadamba nkume, capsules na ọgwụ ophthalmic iji hụ na nchekwa na ịdị irè nke ọgwụ. N'ime ụlọ ọrụ nri, methylcellulose, dị ka ihe mgbakwunye nri, kwadoro dị ka ihe nchebe site n'aka ụlọ ọrụ nchekwa nri n'ọtụtụ mba ma na-ejikarị eme ihe na nri dị mma dị ka nri ndị na-enweghị calorie na nri ndị na-enweghị gluten.
5. Nkwụsi ike na chemical inertness
Methylcellulose nwere ezigbo nkwụsi ike kemịkalụ ma nwee ike ịnọgide na-arụ ọrụ ya na gburugburu acidic na alkaline. Nke a na-enye ya ohere ịnọgide na-arụ ọrụ n'okpuru ọnọdụ dị oke egwu ma na-ejikarị eme ihe na mmepụta mmepụta ihe. Tụkwasị na nke ahụ, kemịkalụ kemịkalụ nke methylcellulose na-eme ka ọ ghara imeghachi omume na ihe ndị ọzọ, a pụkwara iji ya mee ihe dị ka ihe nkpuchi ma ọ bụ stabilizer na ihe ndị mejupụtara iji gbasaa ndụ ndụ nke ngwaahịa ma melite arụmọrụ ngwaahịa.
6. Mwepu mmiri na ihe na-eme ka mmiri dị nro
Methylcellulose nwere ezigbo mmịnye mmiri na ihe na-eme ka mmiri dị mma, ọ pụkwara ịmịkọrọ mmiri nke ya ugboro ugboro. Ya mere, na ụlọ ọrụ nri, a na-eji methylcellulose mee ihe dị ka ihe na-eme ka nri dị nro ma dị ọhụrụ. Na ngwaahịa nlekọta onwe onye, a na-eji methylcellulose mee ihe na ude akpụkpọ anụ, shampoos na ngwaahịa ndị ọzọ iji nyere akpụkpọ ahụ na ntutu aka ijide mmiri ma nye mmetụta na-ekpo ọkụ.
7. Nkwụsi ike na nkwusioru
Methylcellulose nwere ike ịbawanye viscosity nke ngwọta n'ụzọ dị irè, nke mere na a na-akwụsịtụ ihe ndị siri ike n'ime mmiri mmiri iji gbochie mmiri ozuzo na stratification. Njirimara a na-eme ka ọ nwee uru ngwa dị mkpa n'ịkwadebe ngwaahịa dị ka ihe ọṅụṅụ, condiments, na nkwụsị ọgwụ. N'otu oge ahụ, ọ nwekwara ike imeziwanye uto nke nri mmiri mmiri ma kwalite ahụmịhe uto nke ndị ahịa.
8. Nkwụsi ike nke okpomọkụ na oke okpomọkụ na-eguzogide
Methylcellulose nwere ezigbo nkwụsi ike na oke okpomọkụ ma nwee ike ịnọgide na-arụ ọrụ ya n'oge a na-eme achịcha na kpo oku. Ya mere, a na-eji ya eme ihe n'ọtụtụ ebe na-emepụta ihe ndị a na-eme achịcha na ihe oriri dị njikere dị ka ihe na-esi ísì ụtọ na mmiri mmiri iji hụ na àgwà na uto nke nri n'oge nhazi.
9. Eco-enyi na enyi
Methylcellulose, dị ka ihe na-emebi emebi, adịghị emerụ gburugburu ebe obibi ma na-egbo mkpa nchekwa gburugburu ebe obibi ọgbara ọhụrụ. Enwere ike imebi ya site na microorganisms na gburugburu ebe obibi, na-ebelata mmetụta na gburugburu ebe obibi. Ya mere, a na-ewere methylcellulose dị ka ihe ọkụkụ na-acha akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi, karịsịa na mpaghara nke ihe owuwu ụlọ na nkwakọ ngwaahịa, ebe ngwa ya nwere mkpa gburugburu ebe obibi.
10. Ntọhapụ na-achịkwa ọgwụ ọjọọ
Methylcellulose nwere mmetụta ntọhapụ a na-achịkwa dị mkpa na nkwadebe ọgwụ. N'ihi na ọ nwere ike ịmepụta gel viscous na tract gastrointestinal, ọ nwere ike jiri nwayọọ nwayọọ hapụ ọgwụ ọjọọ, mee ka ogologo oge nke ọgwụ na-arụ ọrụ, ma melite irè ọgwụ. A na-ejikarị Methylcellulose akwadebe mbadamba ihe na-adịgide adịgide na mkpuchi microcapsule iji kwalite usoro ntọhapụ nke ọgwụ, belata ugboro ọgwụ, ma kwalite ahụmahụ ọgwụ ndị ọrịa.
N'ihi njirimara ọrụ ya pụrụ iche, a na-eji methylcellulose eme ihe n'ọtụtụ ebe. Ọ bụghị naanị ihe mgbakwunye na-arụ ọrụ dị mkpa na nri na ụlọ ọrụ ọgwụ, ma na-arụkwa ọrụ dị mkpa na mpaghara mmepụta ihe dị ka ihe owuwu na ihe ịchọ mma. Site na ọganihu na-aga n'ihu nke nkà na ụzụ na mgbasawanye nke ngwa, a ga-anọgide na-amụ ihe na-arụ ọrụ nke methylcellulose na ịmepụta ihe ngwọta ọhụrụ maka ụlọ ọrụ dị iche iche.
