Yazi PLA impahla materials 3D ephrintiwe

amakhasimende amaningi nabangane engibuza PLA kuyinto plastic? Nansi inkulumo anolaka ngalokho kuba PLA namuhla.

PLA yiyona isifinyezo English polylactic acid, okuyinto ibhalwe kanje: polylacticacid. Polylactic acid (PLA) kuyinto inoveli biobased futhi impahla okubolayo ezenziwe ngezinto isitashi eluhlaza ehlongozwayo ngu isitshalo ezivuselelekayo ezifana corn. I isitashi impahla eluhlaza is etholwe saccharification ukuthola glucose, bese glucose futhi uhlobo athile isibilile ukukhiqiza ephezulu msulwa acidosis acid, bese othile isisindo yamangqamuzana polylactic acid is kuhlelwe umqondo ngu zamagama zamakhemikhali. It has biodegradability ezinhle. Ngemva ukusetshenziswa, kungashiwo ngokuphelele ukwehliswa isithunzi nezilwanyana ezincane ngokwemvelo ngaphansi kwezimo ezithile, futhi ekugcineni ukhiqiza carbon dioxide futhi amanzi, okungadingi zingcolisa indawo esizungezile. Lokhu kuzuzisa kakhulu ukuba imvelo futhi libhekwa njengenkondlo impahla imvelo.

Lo mbiko waphetha ngokuthi imiphumela phambili, mercury cadmium, i-chromium, biphenyl, futhi diphenyl ether babe ehambisana engu-11-EU umyalelo ku ukusetshenziswa izinto kuvinjelwe, futhi imiphumela isampula 001 awazange itholiwe. ND is Not dected.

Zonke survey ezingenhla zibonisa ukuthi PLA sisetshenziselwa izinto ezinhle, kodwa yokuphepha kokudla ngempela kuyindaba yokukhathalelwa ngokungathi enkulu kubo bonke, noma uqaphele.

Ngivumele sixoxe ngabanye amaphutha kanye nezingozi ezicashile of PLA. Okokuqala, PLA akuyona amelana lokushisa eliphezulu, futhi ngokuyisisekelo uqala deform azungeze 60 °. Njengoba isikhunta ukudla, kumele kube abandayo ngayo; PLA impahla kungenziwa phansi, okuyinto inzuzo futhi abaphumeleli. Nakuba kuba imvelo, idinga 3D ukunyatheliswa umkhiqizo-grade izinto. Luhlala Isikhathi Eside ibhodi iDemo; enqubeni ukuphrinta, ngoba ephezulu lokushisa ukuncibilika, kuyoba ukuvikela izinhlayiya, nakuba izinhlayiya ngokwabo-non-anobuthi, kodwa lena kancane like PM2.5, ukuphefumula eside noma ezinye umonakalo emaphashini womuntu, Ngakho-ke, isikhala ukuphrinta 3D is okungcono umoya.

Ngakho-ke, PLA kuyinto impahla imvelo ukuthi wonke umuntu angasebenzisa ngokuzethemba.

 Ekugcineni ememeza iziqubulo, ubuchwepheshe sishintsha ukuphila, 3D yokunyathelisa isuka amaphupho ukuba ngokoqobo!
