Polyhydroxyalkanoate PHA

ʻO ka Polyhydroxyalkanoate i hoʻopau ʻia e like me PHA, he huaʻōlelo maʻamau no ka papa o nā polyesters kaumaha molekala kiʻekiʻe i hoʻohui ʻia e nā microorganism. Hana ʻia ka PHA mai ka kulina, ka ʻuala a me nā biomass e pili ana i ka starch a i ʻole straw cellulose ma ke ʻano he mea maka, fermented e hana i ka lactic acid, a hoʻomaʻemaʻe hou ʻia a polymerized no ka hoʻomākaukau ʻana i ka PLA maʻemaʻe kiʻekiʻe, ʻo ia ka mea pili i ke kaiapuni, non-toxic, antibacterial, lapalapa. hiki ke pale a me ka biocompatibility maikaʻi.

PHA injection molding grade, blister grade, blow film grade, foam grade, a me nā mea biodegradable piha loa ma ka laina holoʻokoʻa. ʻO nā PHA kekahi ʻano o nā mea polyhydroxyalkanoates (PHA), ʻo ia kahi mea biopolymer i hoʻopili pololei ʻia e ka microbial fermentation i nā microorganism. Loaʻa i nā PHA nā waiwai waiwai nui e like me ka biocompatibility, biodegradability, a me nā waiwai piezoelectric. Loaʻa iā lākou ka maikaʻi o ka hoʻohana ʻana a me ka hoʻoponopono ʻana i nā waiwai, a ua like ko lākou mau waiwai kumu me ka polypropylene. Hiki iā lākou ke hana ʻia a hoʻoheheʻe ʻia me ka hoʻohana ʻana i nā mea hana plastik maʻamau e like me ka injection molding, extrusion, film blowing, wire drawing, and molding, a hiki ke hoʻololi i ka hapa nui o nā plastic petroleum based. Hiki ke hoʻomalu ʻia ka helu biodegradation o nā PHA e ka haku ʻana o kā lākou copolymers e like me nā pono noi like ʻole.
