He aha ka mea degradable PLA maka mea noIpu Kopa Pepa Pla?
ʻO ka PLA kahi ʻano hou o ka bio based a me ka mea hiki ke hoʻololi hou ʻia, i hana ʻia me ka starch mai nā kumu mea kanu hiki ke hoʻololi ʻia (e like me ke kulina, ka ʻoki, etc.). Hoʻopili ʻia ka mea maka o ka starch no ka loaʻa ʻana o ka glucose, a laila hoʻoheheʻe ʻia ka glucose a me kekahi mau kānana i mea e hana ai i ka waikawa lactic maʻemaʻe kiʻekiʻe, a laila hoʻohui ʻia ka polylactic acid me kekahi kaumaha molekala e ke ʻano synthesis kemika.
ʻO ka PLA kahi ʻano hou o ka bio based a me ka mea hiki ke hoʻololi hou ʻia, i hana ʻia me ka starch mai nā kumu mea kanu hiki ke hoʻololi ʻia (e like me ke kulina, ka ʻoki, etc.). Hoʻopili ʻia ka mea maka o ka starch no ka loaʻa ʻana o ka glucose, a laila hoʻoheheʻe ʻia ka glucose a me kekahi mau kānana i mea e hana ai i ka waikawa lactic maʻemaʻe kiʻekiʻe, a laila hoʻohui ʻia ka polylactic acid me kekahi kaumaha molekala e ke ʻano synthesis kemika.
He biodegradability maikaʻi ko PLA. Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaʻahaʻa ʻia e nā microorganism i ke ʻano ma lalo o nā kūlana kikoʻī, a i ka hopena e hoʻopuka i ka carbon dioxide a me ka wai, ʻaʻole ia e hoʻohaumia i ke kaiapuni. He mea maikaʻi loa ia i ka pale ʻana i ke kaiapuni a ʻike ʻia ʻo ia he mea pili i ke kaiapuni noʻO nā kīʻaha biodegradable.
He koho maikaʻi ia e hana i ka High Quality Kraft Pla Pepa Salaa kīʻaha hoʻolele a meIpu Pepa Pla.
He kūpaʻa wela maikaʻi ka PLA, ka mahana hana 170 ~ 230 ℃, a me ke kūpaʻa ʻana i ka solvent. ʻO ke kīʻaha pepa i uhi ʻia a me ka uhi kīʻaha i hana ʻia me ka polylactic acid he biocompatibility maikaʻi, gloss, transparency, paʻa a me ka pale wela, a me kekahi mau bacterial resistance, flame retardancy and UV resistance.
