Ese PLA ishobora kwangirika?
•Aside ya polylactic, izwi kandi nka PLA, imaze imyaka myinshi ihari. Ariko, abakora PLA bakomeye baherutse kwinjira ku isoko nyuma yo kubona inkunga iturutse ku bigo binini bishishikajwe no gusimbuza pulasitiki zikozwe mu nganda. None se, PLA ishobora kwangirika?
•Nubwo igisubizo kitari cyoroshye, twahisemo gutanga ibisobanuro no gusaba ababyifuza ko basoma byinshi. PLA ntabwo ibora, ariko ibora. Enzymes zishobora gusenya PLA ntiziboneka cyane mu bidukikije. Proteinase K ni enzyme itera kwangirika kwa PLA binyuze mu gushonga kwa hydrolysis. Abashakashatsi nka Williams mu 1981 na Tsuji na Miyauchi mu 2001 basuzumye ikibazo cyo kumenya niba PLA ishobora kwangirika. Ibisubizo byabo byaganiriweho mu gitabo Biomaterials Science: An Introduction to Medical Materials kandi byatanzwe mu nama y'Umuryango w'Uburayi wa Biomaterials. Dukurikije ayo makuru, PLA igenzurwa ahanini na hydrolysis, ititaye ku bintu byose bikomoka ku binyabuzima. Nubwo abantu benshi bashobora gutekereza ko PLA ishobora kwangirika, ni ngombwa kubigeraho.
•Mu by’ukuri, hydrolysis ya PLA hifashishijwe poroteyine K ni gake cyane ku buryo idahagije kugira ngo iganirweho byinshi mu bumenyi bw’ibinyabuzima. Twizere ko ibi bisobanuye neza ibibazo bijyanye no kwangirika kwa PLA kandi tuzakomeza gushyira imbaraga mu gutanga ibisubizo byiza ku byo ukeneye bya pulasitiki idafite ingaruka ku bidukikije kandi ishobora kwangirika.
IUmwanzuro:
PLA ni pulasitiki ishobora kubora ikoreshwa cyane mu bintu bya buri munsi nko mu mifuka n'ibikombe bikoreshwa rimwe. Ariko, ishobora kwangirika gusa mu nganda zikora ifumbire cyangwa ahantu hadakoreshejwe umwuka, bigatuma kwangirika mu bidukikije bisanzwe bigorana. Ubushakashatsi bwemeje ko PLA ibora gato mu bidukikije byo mu mazi.
