Okwu Mmalite nke polylactic acid BOPLA dabere biaxally
Ihe nkiri Biaxial Oriented poly (lactic acid) (BOPLA) bụ ụdị ihe nkiri ihe nkiri siri ike bio dabere na ogologo oge na ntụgharị transverse nke ihe polylactic acid na crystallization.Usoro ịgbatị Biaxial gụnyere nzọụkwụ-agbatị, 2. Mechanical simultaneous agbatị na m LISIM n'otu oge na-agbatị, dị ka e gosiri na Figure 1. N'iji ya tụnyere usoro nhazi ndị ọzọ, usoro ịgbatị biaxial na-akwalite nhazi molecular nke ihe PLA, na-enye ihe PLA nwere ike dị elu na elu okpomọkụ na-eguzogide, na-ebelata ọkpụrụkpụ nke ngwaahịa iji nweta kasị mma itinye n'ọrụ nke ihe.BOPLA nwere uru nke ihe nrụzi kwụ ọtọ na nke kwụ ọtọ, nghọta dị elu, ikike dị elu na ezigbo mbipụta.Ọ nwere ike dochie ihe nkiri ugbu a na e-azụmahịa lọjistik, nri dị elu, ngwaahịa eletrọnịkị, lamination mpempe akwụkwọ na mpaghara ndị ọzọ.

BOPLA nwere uru atọ na ngwa ahịa.
Nke mbụ, BOPLA bụ ihe nkiri doro anya dabere na bio na ahịa.N'ihi njirimara ihe onwunwe na machinability nke PLA, BOPLA nwere obere mmepụta usoro na obere nhazi ihe isi ike, ma nwee uru nke mkpuchi mmiri na mbipụta nke ihe nkiri polymer omenala, nke na-eme ka ọ nwee atụmanya dị ukwuu n'ọhịa nke ngwa ihe nkiri dị mkpa.
Nke abuo, BOPLA nwere njiri mara mmebi.N'okpuru ọnọdụ nchekwa ọdịnala, BOPLA nwere ike ịnọgide na-arụ ọrụ nke ọma iji kwe nkwa ndụ ngwaahịa ma zere ịbelata ndụ nchekwa nke ngwaahịa njedebe n'ihi oke mbibi oke.N'okpuru ọnọdụ compost, BOPLA nwere ike nweta ọkpụrụkpụ ihe nkiri dị gịrịgịrị n'okpuru otu ihe eji arụ ọrụ, nke mere na ọ nwere ike imebi ngwa ngwa na gburugburu compost.
Nke atọ, BOPLA na-emezu ihe achọrọ nke ụlọ nkwakọba ihe na njem ụgbọ njem, ma nwee ntọala nke ngwa ụlọ ọrụ mmepụta ihe.Na nnwale ịka nká nke BOPLA (FIG.2), ike tensile na-emebi naanị 4.5% mgbe otu afọ gachara yana 5.2% mgbe afọ 2 gachara.Ike mkpuchi okpomọkụ na-ebelata 12.8% mgbe afọ 1 gachara, nke na-emezu ihe achọrọ nke ịrụ ọrụ mkpuchi okpomọkụ.Na ule mmiri BOPLA (Xiamen-Antwerp, FIG. 3), ọ dịghị mgbanwe dị ịrịba ama na ihe nkiri na ọdịdị dị.
