Le filament yePLA entsha ilungele ukupakishwa kokutya

Intambo yePLA

Ukusuka IINJONGO, I-Instituto Tecnológico del Plástico de España, kwithuba lokuthatha inxaxheba kwiprojekthi yaseYurophu YOKWENZAKuyenzeka ukuba kuphuculwe inkqubo yokufumana ifilament yePLA ephucula kakhulu iipropathi zayo zoomatshini, ngaloo ndlela ivumela ukusetyenziswa kwayo ukuveliswa kwezikhongozeli ezitofelweyo ukutshintsha ipolypropylene. Njengoko sele kukhankanyiwe, eyona nto intsha ilele kukusetyenziswa kwesicatshulwa esitsha njengesixhobo sokuvelisa i-polylactic acid, i-PLA, evela kwi-lactide.

Enkosi ngokusetyenziswa kwale teknoloji intsha, sinokuhambisa ngezinto zentsimbi kwaye sisebenzise ngokuthe ngqo amandla ongezelelweyo ukuphucula i-kinetics yempendulo. Konke oku, ngokwexabiso elikhulu lezifundo ezenziweyo malunga nendlela iipropathi zokugqibela ze-biopolymer eziguqulweyo ngayo, zikhokelele ekudalweni kwe I-filament ye-PLA eguquguqukayo kunye ne-200% yomelele kwimpembelelo kunaleyo isetyenziswa ngendlela eqhelekileyo.

I-AIMPLAS iyasimangalisa ngentetho yentsingiselo entsha yePLA yokwenza imveliso yokupakisha.

Olu phuhliso lufezekisiwe emva kweenyanga ezininzi zophando, apho belufuna ukuhlanganisa a i-catalyst entsha enobume bendalo Ukuze kulungiswe i-polymerization ye-lactide, ukufezekisa inkqubo enamandla yokuguqulwa okuphezulu ukufumana i-PLA yobunzima beemolekyuli kunye ne-polydispersity elungileyo yokucoceka okuphezulu.

Njengoko ucinga ngokuqinisekileyo, phakathi kwezibonelelo esizifumanayo ekusebenziseni le filament intsha, gqamisa, umzekelo ukususwa kwamasuntswana enkcenkce kwinkqubo, eya kuthi ikhokelele ngokuthe ngqo kuphuculo lokusingqongileyo kunye nokhuseleko olukhulu lwabasebenzi. Kwelinye icala, le nto intsha, enkosi ekuphuculeni iipropathi zayo, inokusetyenziselwa ukwenziwa ngenaliti kunye nokubumba ukutya ngokupakishwa ukutshintsha ipolypropylene. Ndiyabulela koku, ukusetyenziswa kweplastiki eqhelekileyo kuya kuncitshiswa, kulungiselelwe ukusetyenziswa kwemithombo enokuboliswa yintsholongwane.
