Introduction to biaxially oriented polylactic acid BOPLA

ʻO ke kiʻiʻoniʻoni Biaxially oriented poly (lactic acid) (BOPLA) he ʻano kiʻi kiʻi bio-based kiʻekiʻe kiʻekiʻe i loaʻa ma hope o ka lōʻihi a me ka transverse o ka polylactic acid material a me ka crystallization.ʻO ke kaʻina hana hoʻolōʻihi Biaxial e pili ana i ka Step-stretching, 2. Mechanical simultaneous stretching a m LISIM simultaneous stretching, e like me ka mea i hōʻike ʻia ma ka Figure 1. Ke hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe, hoʻolaha ka biaxial stretching process i ka molecular orientation o nā mea PLA, hāʻawi i nā mea PLA me ka ikaika kiʻekiʻe a pale wela kiʻekiʻe, a hoʻemi i ka mānoanoa o nā huahana e hoʻokō i ka hoʻohana maikaʻi ʻana i nā mea.Loaʻa i ka BOPLA nā mea maikaʻi o nā waiwai mechanical vertical a horizontal, kiʻekiʻe transparency, kiʻekiʻe permeability a me ka paʻi maikaʻi.Hiki iā ia ke hoʻololi nui i ka kiʻiʻoniʻoni i hoʻohana ʻia i kēia manawa i ka logistic e-commerce, nā meaʻai kiʻekiʻe, nā huahana uila, ka lamination pepa-plastic a me nā māla ʻē aʻe.

Kiʻi 1. Diagram o ke kaʻina hoʻolōʻihi biaxial

Loaʻa iā BOPLA ʻekolu mau pono i ka noi mākeke.

ʻO ka mea mua, ʻo BOPLA ka kiʻi ʻoniʻoni ʻoniʻoni bio-based ʻoi loa ma ka mākeke.Mahalo i nā hiʻohiʻona waiwai a me ka machinability o PLA, ʻoi aku ka liʻiliʻi o ka BOPLA i nā hana hana a me ka liʻiliʻi o ka paʻakikī, a loaʻa iā ia nā pōmaikaʻi o ka wai ʻole a me ka paʻi ʻana o ka kiʻiʻoniʻoni polymer kuʻuna, kahi e loaʻa ai ka manaʻo nui i ke kahua o ka noi kiʻi ʻoniʻoni.

ʻO ka lua, loaʻa iā BOPLA nā hiʻohiʻona degradable controllable.Ma lalo o nā kūlana mālama maʻamau, hiki i ka BOPLA ke mālama i ka hana maikaʻi e hōʻoiaʻiʻo i ke ola o nā huahana a pale aku i ka pōkole o ke ola o nā huahana terminal ma muli o ka wikiwiki degradation.Ma lalo o nā kūlana compost, hiki i ka BOPLA ke hoʻokō i ka mānoanoa kiʻiʻoniʻoni lahilahi ma lalo o nā waiwai mechanical like, i hiki ai ke hoʻohaʻahaʻa wikiwiki i ka honua compost.

ʻO ke kolu, hoʻokō ʻo BOPLA i nā koi o ka warehousing maʻamau a me ka lawe logistic, a loaʻa ke kumu o ka noi ʻoihana.I ka BOPLA's accelerated aging test (FIG.2), 4.5% ka pohō wale no ka ikaika tensile ma hope o 1 makahiki a me 5.2% ma hope o 2 makahiki.ʻO ka ikaika sealing wela e hoʻonui i ka 12.8% ma hope o 1 makahiki, e kūpono ana i nā koi o ka hana hoʻopaʻa wela.Ma nā ho'āʻo kai BOPLA (Xiamen-Antwerp, FIG. 3), ʻaʻohe loli nui i nā waiwai kiʻiʻoniʻoni a me nā hiʻohiʻona.

ʻO ka hoʻāʻo ʻelemakule wikiwiki ʻo BOPLA
