PLA ò nwere ike imebi emebi?
•Adịla adịla kemgbe ọtụtụ afọ. Agbanyeghị, ndị na-emepụta PLA bụ isi abatala n'ahịa n'oge na-adịbeghị anya mgbe ha nwetara ego n'aka nnukwu ụlọ ọrụ ndị chọrọ ịgbanwe plastik sịntetik. Ya mere, PLA ò nwere ike ire ere?
•Ọ bụ ezie na azịza ya adịghị mfe, anyị kpebiri inye nkọwa ma kwado ịgụkwu ihe nye ndị nwere mmasị. PLA abụghị ihe a na-apụghị ịgbagha agbagha, mana ọ na-emebi emebi. A naghị ahụkarị Enzymes ndị nwere ike imebi PLA na gburugburu ebe obibi. Proteinase K bụ enzyme nke na-akwalite mmebi nke PLA site na hydrolysis. Ndị nchọpụta dịka Williams na 1981 na Tsuji na Miyauchi na 2001 lere anya na okwu ma PLA nwere ike ịgbagha agbagha. A tụlere nsonaazụ ha n'akwụkwọ Biomaterials Science: An Introduction to Medical Materials ma gosipụta ya na nzukọ nke European Biomaterials Society. Dịka isi mmalite ndị a si kwuo, a na-achịkwa PLA site na hydrolysis, n'adabereghị na ihe ọ bụla metụtara ndụ. Ọ bụ ezie na ọtụtụ mmadụ nwere ike iche na PLA nwere ike ịgbagha agbagha, ọ dị mkpa ịghọta nke a.
•N'eziokwu, mmiri nke PLA site na proteinase K dị oke ụkọ nke na ọ dịghị mkpa ka a tụlee ya nke ọma na sayensị ihe gbasara ihe. Anyị nwere olileanya na nke a ga-eme ka nsogbu ndị gbara PLA gburugburu ghara ịdị irè doo anya, anyị ga-agakwa n'ihu na mbọ anyị na-agba iji nye azịza kacha mma maka mkpa plastik gị nke na-adịghị emebi gburugburu ebe obibi na nke na-emebi emebi.
In mmechi:
PLA bụ plastik a na-ere ere nke a na-ejikarị eme ihe kwa ụbọchị dịka akpa na iko a na-atụfu atụfu. Agbanyeghị, ọ nwere ike ire ere naanị na nhazi nke ihe ndị e ji emepụta ihe ma ọ bụ gburugburu ebe a na-agbaze nri nke na-eme ka mmebi na gburugburu ebe obibi ndị e kere eke sie ike. Nnyocha egosila na PLA na-ere ere nke ukwuu na gburugburu ebe obibi mmiri.
