Kusuka I-AIMPLAS, Technological Institute of Plastics of Spain, ngesikhathi sokubamba iqhaza kwayo kuphrojekthi yaseYurophu I-InnOREX, kube nokwenzeka ukuthuthukisa inqubo entsha yokuthola intambo ye-PLA ezithuthukisa kakhulu izakhiwo zayo zomshini, ngaleyo ndlela ivumele ukusetshenziswa ukwenziwa kweziqukathi ezijojowe esikhundleni se-polypropylene. Njengoba kushiwo, ubusha bangempela bukhona ekusetshenzisweni kwe-extruder entsha njenge-reactor yokukhiqiza i-polylactic acid, i-PLA, evela ku-lactide.
Ngenxa yokusetshenziswa kwalobu buchwepheshe obusha, singakwazi ukukhipha izakhi zensimbi futhi sisebenzise ngqo amandla ahlukile ukwenza ngcono i-kinetics yokuphendula. Konke lokhu, ngokusho kwenani elikhulu lezifundo ezenziwe ukuthi izakhiwo zokugcina ze-biopolymer ziguqulwa kanjani, kuholele ekwakhiweni kwe intambo eguquguqukayo ye-PLA kuze kufike ku-200% enamandla kumthelela kunomunye osetshenziswe ngendlela ejwayelekile.
I-AIMPLAS iyasimangaza ngokwethulwa kwento entsha ye-PLA intambo yokwenziwa kokupakisha kokudla.
Lokhu kuthuthuka kufinyelelwe ngemuva kwezinyanga eziningi zocwaningo, lapho ebefuna khona ukuhlanganisa i- a i-catalyst entsha yemvelo enobungani ukuze kuvuselele i-polymerization ye-lactide, kufinyelele inqubo enamandla yokuguqulwa okuphezulu ukuthola i-PLA yesisindo samangqamuzana aphezulu kanye ne-polydispersity enhle yokuhlanzeka okuphezulu kokukhanya.
Njengoba ucabanga impela, phakathi kwezinzuzo esizithola ekusetshenzisweni kwale ntambo entsha, gqamisa, ngokwesibonelo, ukususwa kwezinhlayiya zensimbi kunqubo, okuzoholela ngqo ekuthuthukisweni kwemvelo kanye nokuphepha okukhulu kwabasebenzi. Ngakolunye uhlangothi, le nto entsha, ngenxa yokuthuthuka kwezakhiwo zayo, ingasetshenziswa ekwenziweni ngomjovo nange-thermoforming yokupakisha kokudla esikhundleni se-polypropylene. Ngenxa yalokhu, ukusetshenziswa kwepulasitiki ejwayelekile kuzoncishiswa, kuvuna ukusetshenziswa kwemithombo ebolayo.
