He aha ke kalapona?

ʻO PLA kekahi o nā huahana plastic degradable mainstream. ʻO ka polylactic acid kahi polymer i hoʻopili ʻia mai ka lactic acid ma ke ʻano he kumu kumu. I kēia manawa, ʻo ia ka mea ʻoi loa, ka nui a me ka hoʻohana nui ʻia o ka plastic biodegradable ma ka honua.

ʻElua mau ala no ka hana PLA, ʻo ia ka polymerization ring-open lactide a me ka polycondensation pololei, kahi i hoʻohana nui ʻia ai ka polymerization ring-open lactide. I ka lactide ring-open polymerization, ʻo ka synthesis a me ka hoʻomaʻemaʻe ʻana o ka lactide waena ka ʻenehana kumu a me ka paʻakikī i ka hana. He paʻakikī nā kūlana hopena, paʻakikī ke kaʻina hana, kiʻekiʻe nā koi ʻenehana, a kiʻekiʻe ke kumukūʻai hana.
