Cellulose Acetate Butyrate, nke akpọchiri dị ka CAB, nwere usoro kemịkal (C6H10O5) n na ịdị arọ molekụla nke nde mmadụ. Ọ bụ ntụ ntụ siri ike dị ka ihe na-agbaze na ụfọdụ ihe mgbaze organic, dị ka acetic acid na acetic acid. Solubility ya na-abawanye na okpomọkụ na-abawanye. Cellulose acetate butyrate nwekwara ụfọdụ nkwụsi ike nke okpomọkụ na ọ naghị adị mfe ire ere na ụlọ okpomọkụ.

Cellulose Acetate Butyrate nwere ihe ndị magburu onwe ya dị ka mmiri na-eguzogide mmiri, nguzogide UV, nguzogide oyi, mgbanwe, nghọta, na mkpuchi eletrik, ma nwee ezigbo ndakọrịta na resins na nnukwu ihe na-esi ísì ụtọ.

Na mgbakwunye, ọ nwekwara ezigbo bioacompatibility na ọ gaghị enwe mmetụta ọjọọ na ahụ mmadụ ma ọ bụ gburugburu ebe obibi.

Aro maka iji cellulose acetate butyrate

Mgbe ị na-eji cellulose acetate butyrate, e nwere ụfọdụ aro na ịkpachara anya nke nwere ike inye aka rụọ ọrụ ya nke ọma. Nke mbụ, cellulose acetate butyrate kwesịrị ka a mịrị amị tupu ejiri ya mee ka ọ dịkwuo mma na nkwụsi ike ya. Nke abuo, n'oge nhazi, a ga-ezere okpomọkụ dị elu na ọnọdụ acidic iji gbochie mmebi na mmebi nke cellulose. Tụkwasị na nke a, a ghaghị ịgbaso ụkpụrụ na iwu ndị dị mkpa n'oge eji eme ihe iji hụ na nrubeisi na nchekwa nke ihe ndị ahụ.
