Ihe Mgbanwe Agbanwe Agbanwe Injection Na-emebi Ihe

Ọtụtụ ụzọ ụlọ ọrụ nwere ike iji ya mee ihe (ya bụ oke molekul) PLA. A na-eji monomers abụọ eme ihe: lactic acid, na cyclic di-ester, lactide. Ụzọ a na-emekarị na-aga PLA bụ mgbanaka-mepe polymerization nke lactide nwere ihe dị iche iche metal catalysts (na-emekarị tin octoate) na ngwọta ma ọ bụ dị ka nkwusioru. Mmeghachi omume nke metal-catalyzed na-eme ka ịgba ọsọ nke PLA, na-ebelata stereoregularity ya tụnyere ihe mmalite (na-emekarị starch ọka).

PLA na-agbaze n'ọtụtụ ihe mgbaze organic. Ethyl acetate, n'ihi na ọ dị mfe ịnweta ya na obere ihe ize ndụ nke iji, bụ nke kachasị mmasị. Ihe nbipute PLA 3D filament na-agbaze mgbe etinyere ya na ethyl acetate, na-eme ka ọ bụrụ ihe mgbaze bara uru maka ihicha isi ebipụta extruder 3D ma ọ bụ wepụ ihe nkwado PLA. Ebe a na-esi esi nke ethyl acetate dị ala iji mee ka PLA dị nro n'ime ọnụ ụlọ, dị ka iji acetone vapor na-eme ka ABS dị nro.

Ihe mgbaze ndị ọzọ dị mma ị ga-eji gụnyere propylene carbonate, nke dị mma karịa ethyl acetate mana ọ siri ike ịzụta na azụmaahịa. Enwere ike iji Pyridine agbanyeghị nke a adịghị mma karịa ethyl acetate na propylene carbonate. O nwekwara isi ajọ azụ dị iche.
