Ethyl cellulose bụ polymer dị iche iche nwere ngwa ngwa dị iche iche, sitere na ọgwụ na mkpuchi na ihe mgbakwunye nri. Ngwongwo ya nwere ike ịdị iche iche dabere na ọkwa ya, nke a na-ekpebi site na ihe ndị dị ka ịdị arọ molekụla, ogo nke nnọchi, na nkesa nha nha.
1. Okwu Mmalite Ethyl Cellulose
Ethyl cellulose bụ ihe sitere na cellulose, polymer eke dị na mgbidi cell osisi. A na-emepụta ya site na ethylation nke cellulose, ebe a na-eji otu ethyl dochie ìgwè hydroxyl dị na azụ azụ cellulose. Mgbanwe a na-enye ethyl cellulose ihe pụrụ iche, gụnyere ezigbo ike imepụta fim, nguzogide kemịkalụ, na nkwụsi ike ọkụ.
2.Ọ dị ala ruo Ọkara Ọkara Akara Molecular:
Akara ule ndị a na-enwekarị ihe ọ̀tụ̀tụ̀ molekụla sitere na 30,000 ruo 100,000 g/mol.
A na-eji njirimara viscosity ha dị ala yana ọnụego mgbasa ngwa ngwa ma e jiri ya tụnyere akara ule dị elu nke molekụla.
Ngwa:
Mkpuchi: A na-eji ya dị ka ihe eji eme ihe na mkpuchi maka mbadamba nkume, mkpụrụ ọgwụ na granules na ọgwụ.
Mwepụta a na-achịkwa: A na-arụ ọrụ na sistemụ nnyefe ọgwụ na-achịkwa ebe achọrọ mgbasa ngwa ngwa.
Ink: A na-eji ya eme ihe dị ka ndị na-emepụta ihe na ndị na-emepụta ihe nkiri n'ime akwụkwọ ink.
3.High Molecular arọ akara ule:
Akara ule ndị a nwere ihe dị arọ nke na-akarị 100,000 g/mol.
Ha na-egosiputa viscosity dị elu yana ọnụego mgbasa nwayọ nwayọ, na-eme ka ha dabara adaba maka usoro mwepụta na-adịgide adịgide.
Ngwa:
Mwepụta na-adịgide adịgide: Ọ dị mma maka imepụta ụdị usoro ntọhapụ na-adịgide adịgide na ụlọ ọgwụ, na-enye mwepụta ọgwụ ogologo oge.
Encapsulation: Ejiri ya na teknụzụ mkpuchi mkpuchi maka ntọhapụ nke ekpomeekpo, ísì ụtọ na ihe ndị na-arụ ọrụ.
Ihe nkiri mgbochi: A na-arụrụ ya ọrụ dị ka mkpuchi mgbochi na nkwakọ ngwaahịa nri iji kwalite ndụ adịkwa ma gbochie ọbịbịa mmiri.
4.Degree nke nnọchi (DS) iche iche:
Ethyl cellulose nwere ike inwe ogo dị iche iche nke nnọchi, na-egosi nkezi ọnụọgụ ethyl otu n'otu anhydroglucose n'ime agbụ cellulose.
Akara ule nwere ụkpụrụ DS dị elu nwere otu ethyl karịa otu cellulose, na-ebute mmụba hydrophobicity na mbelata mmiri solubility.
Ngwa:
Mgbochi mmiri: A na-eji akara DS dị elu mee ihe na mkpuchi na ihe nkiri ebe mmiri na-eguzogide dị oké egwu, dị ka ihe mgbochi mmiri maka mbadamba nkume na capsules.
Nguzogide mgbaze: Kwesịrị ekwesị maka ngwa chọrọ iguzogide ihe mgbaze organic, dị ka ink na mkpuchi maka mbipụta na nkwakọ.
5. Akụkụ dị iche iche nha nha:
Ethyl cellulose dị na nkesa nha nha nha nha dị iche iche, sitere na ụmụ irighiri ihe dị ka micrometer ruo nanometer ntụ ntụ.
Ọma urughuru nha na-enye uru dị ka mma dispersibility, smoother mkpuchi, na enwekwukwa ndakọrịta na ndị ọzọ Efrata.
6. Ngwa:
Nanoencapsulation: A na-eji ahụ nanoscale ethyl cellulose eme ihe na nanomedicine maka nnyefe ọgwụ, na-eme ka nnyefe ezubere iche na ịkwalite nrụpụta ọgwụgwọ.
Mkpuchi Nano: A na-eji ntụ ntụ ethyl cellulose dị mma na mkpuchi ọpụrụiche, dị ka mkpuchi mkpuchi maka ngwa eletrọnịkị na-agbanwe agbanwe na ngwaọrụ biomedical.
Ethyl cellulose bụ polymer na-agbanwe agbanwe nwere ngwa dị iche iche n'ofe ụlọ ọrụ, na akara ule ya dị iche iche na-enye ihe eji eme ya iji zute ihe ndị chọrọ nhazi. Site na akara ule dị ala ruo elu dị elu ruo n'ụdị dị iche iche dabere na ogo ngbanwe na nkesa nha, ethyl cellulose na-enye ọtụtụ nhọrọ maka ndị na-emepụta ihe na-achọ ihe ngwọta na nnyefe ọgwụ, mkpuchi, mkpuchi, na karịa. Ịghọta njirimara nke ọkwa ọ bụla dị oke mkpa maka ịkwalite arụmọrụ yana nweta nsonaazụ achọrọ na ngwa dị iche iche.
