Ese PLA ibora ibinyabuzima?
•Acide Polylactique, izwi kandi nka PLA, imaze imyaka myinshi. Nyamara, abatunganya ibicuruzwa bikomeye bya PLA binjiye mumasoko nyuma yo kubona inkunga mumasosiyete manini ashishikajwe no gusimbuza plastike yubukorikori. None, PLA irashobora kubora?
•Mugihe igisubizo kitari cyoroshye, twahisemo gutanga ibisobanuro tunasaba gukomeza gusoma kubabishaka. PLA ntabwo ishobora kwangirika, ariko irashobora kwangirika. Enzymes zishobora gusenya PLA ntizikunze kuboneka mubidukikije. Proteinase K ni enzyme itera kwangirika kwa PLA binyuze muri hydrolysis. Abashakashatsi nka Williams mu 1981 na Tsuji na Miyauchi mu 2001 bakoze ubushakashatsi ku kibazo cyo kumenya niba PLA idashobora kwangirika. Ibisubizo byabo byaganiriweho mu gitabo cyitwa Biomaterials Science: Intangiriro y'ibikoresho by'ubuvuzi kandi bitangwa mu nama y'umuryango w’iburayi w’ibinyabuzima. Nk’uko aya masoko abivuga, PLA igenzurwa cyane na hydrolysis, idashingiye ku binyabuzima byose. Nubwo abantu benshi bashobora gutekereza ko PLA idashobora kwangirika, ni ngombwa kubimenya.
•Mubyukuri, hydrolysis ya PLA na proteinase K ni gake cyane kuburyo atari ngombwa bihagije kuganirwaho mubumenyi bwibinyabuzima. Turizera ko ibi bisobanura neza ibibazo bijyanye na biologiya ya PLA kandi tuzakomeza imbaraga zacu kugirango dutange ibisubizo byiza kubidukikije byangiza ibidukikije kandi byangiza ibidukikije.
In umwanzuro:
PLA ni plastiki ibora ikoreshwa cyane mubintu bya buri munsi nkimifuka ikoreshwa hamwe nibikombe. Nubwo bimeze bityo ariko, irashobora gutesha agaciro ifumbire mvaruganda cyangwa anaerobic igogorwa ryibiryo, bigatuma kwangirika mubidukikije bisanzwe bigoye. Ubushakashatsi bwemeje ko PLA itesha agaciro ibidukikije byo mu nyanja.
