Mmetụta ọdịnaya methoxy na ọdịnaya hydroxypropoxy na HPMC

Ọdịnaya methoxy na ọdịnaya hydroxypropoxy dị na Hydroxypropyl Methylcellulose (HPMC) na-emetụta njirimara ya na arụmọrụ ya na ngwa dị iche iche.Nke a bụ otu paramita ọ bụla si emetụta HPMC:

1. Ọdịnaya Methoxy:
   • Ọdịnaya methoxy na-ezo aka n'ogo ngbanwe (DS) nke otu methoxy dị n'ọkpụkpụ azụ cellulose.Ọ na-ekpebi mkpokọta hydrophobicity nke HPMC.
   • Ọdịnaya methoxy dị elu na-eduga n'ịdị elu mmiri solubility na ala gelation okpomọkụ.HPMC nwere ọdịnaya methoxy dị elu na-agbaze ngwa ngwa na mmiri oyi, na-eme ka ha dabara maka ngwa ebe achọrọ hydration ngwa ngwa.
   • Ọdịnaya methoxy na-emetụta ike ịgbara HPMC.N'ozuzu, DS dị elu na-ebute viscosity dị elu na obere mkpokọta.Ngwongwo a bara uru na ngwa ndị dị ka adhesives, ebe a na-achọ njigide mmiri dị mma na viscosity.
   • Ọdịnaya methoxy dị elu nwekwara ike imetụta ihe na-emepụta ihe nkiri, nrapado, yana ndakọrịta na ihe ndị ọzọ.Ọ nwere ike inye aka n'ịmepụta ihe nkiri na-agbanwe agbanwe na nke jikọrọ ọnụ na ngwa dịka mkpuchi na mbadamba ọgwụ.
2. Ọdịnaya Hydroxypropoxy:
   • Ọdịnaya hydroxypropoxy na-ezo aka n'ogo ngbanwe (DS) nke otu hydroxypropyl na ọkpụkpụ azụ cellulose.Ọ na-ekpebi mkpokọta hydrophilicity na njigide mmiri nke HPMC.
   • Ịba ụba ọdịnaya hydroxypropoxy na-akwalite ikike njide mmiri nke HPMC.Ọ na-eme ka ike HPMC na-ejigide mmiri n'ụdị usoro, na-ebute ogologo ọrụ na-arụ ọrụ yana mma mmachi na ihe cimenti, dị ka ngwa agha na taịlị.
   • Ọdịnaya Hydroxypropoxy na-emetụtakwa okpomọkụ gelation na ihe na-emepụta ihe nkiri nke HPMC.DS dị elu nke otu hydroxypropyl na-ebelata okpomọkụ gelation ma nwee ike iduga n'ichepụta ihe nkiri ka mma na ntinye na mkpuchi na ngwa ọgwụ.
   • Oke nke ọdịnaya methoxy na ọdịnaya hydroxypropoxy na-emetụta nguzozi nke akụrụngwa hydrophilic na hydrophobic na HPMC.Site n'ịgbanwe nha a, ndị na-emepụta nwere ike ịhazi arụmọrụ nke HPMC iji mezuo ihe achọrọ ngwa ngwa, dị ka viscosity, njide mmiri, na nhazi ihe nkiri.

Na nchịkọta, ọdịnaya methoxy na ọdịnaya hydroxypropoxy nke HPMC na-arụ ọrụ dị oke mkpa n'ịchọpụta solubility ya, ike njupụta, njide mmiri, okpomọkụ gelation, ihe na-emepụta ihe nkiri, nrapanye, na ndakọrịta na ihe ndị ọzọ.Site n'ịchịkwa parampat ndị a, ndị na-emepụta nwere ike mepụta HPMC nwere ọtụtụ akụrụngwa dabara adaba maka ngwa dị iche iche na ụlọ ọrụ dị ka ihe owuwu, ọgwụ, nri, ihe ịchọ mma na nlekọta onwe onye.
