A. He aha ka PBAT
ʻO ka PBAT kahi plastic biodegradable thermoplastic.ʻO ia ka Poly (butyleneadipate-co-terephthalate).Loaʻa iā ia nā hiʻohiʻona o PBA a me PBT.Loaʻa iā ia ka ductility maikaʻi a me ka elongation i ka wā haki.Loaʻa iā ia ka wela maikaʻi a me ka hopena hopena;Eia kekahi, loaʻa iā ia ka biodegradability maikaʻi loa a ʻo ia kekahi o nā mea ikaika loa a me ka mākeke-degradable mea i loko o ka noiʻi plastics biodegradable.
B. He aha ka hiʻona o PBAT
1) 100% biodegradable, hoʻohaʻahaʻa ʻia i loko o ka wai a me ka carbon dioxide i loko o 6 mau mahina ma lalo o nā kūlana composting ʻoihana, e like me nā kūlana EN13432 a me ASTM D6400
2) Ma muli o ka PBAT i hoʻololi ʻia i nā mea biodegradable holoʻokoʻa, me ka ʻole o ka starch, me ke kaʻina hana maikaʻi, ka ikaika mechanical a me ka hoʻihoʻi.
3) Me ke kiʻekiʻe o ka hoʻokumu ʻana i nā mea kūlohelohe, e hōʻemi ana i nā kumu waiwai a me nā kalapona kalapona
4) Nā waiwai kino a me nā mīkini maikaʻi.
5) Hoʻonui i ka wā hana, ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana, hoʻemi nui ʻia ka ʻike wela
6) Hiki ke hana ʻia ma ka wikiwiki kiʻekiʻe ma nā mea extrusion maʻamau maʻamau, me ka ʻole o ka maloʻo ʻana ma mua o ka hana ʻana
7) Me nā mea hoʻololi hoʻololi hoʻohuihui ʻoihana, hiki ke hoʻololi i nā hoʻonā huahana e like me nā pono noi noi
8) ʻOi aku ka maikaʻi o ka hana ʻana o ka huahana, ʻoi aku ka lōʻihi o ke ola
9) ʻO ke kūpaʻa paʻa o ka hoʻonā wela wela, maikaʻi ka hoʻihoʻi hou ʻana o nā mea, hiki ke kū i nā mahana kiʻekiʻe a me ka ʻoki ikaika.
10) ʻAʻole i loko o nā plasticizers e like me ka glycerin, ka hoʻoili ʻana a me ke kaʻina hoʻokomo ʻaʻole pili, ʻaʻole ʻaila.
11) Hiki ke hālāwai me FDA, EC2002 a me nā koi pili meaʻai ʻē aʻe
12) ʻOi aku ka lōʻihi o ke ola o ka huahana kiʻiʻoniʻoni ma mua o ka mea i hoʻokumu ʻia i ka starch, hiki i ka 10-20 micron film ke loaʻa kahi ola o 8-12 mau mahina ma lalo o nā kūlana wela o ka lumi kūlohelohe;ʻO ka huahana papa o 20 micron a i ʻole hiki ke hiki i 12-18 mau mahina papa.
13) PBAT-based blended modified products, and other biodegradable materials like PBS, PLA, PHA, PPC, starch, etc.
14) ʻAʻole kūpono nā polyolefins kuʻuna e like me PE, PP, PO a me nā mea ʻē aʻe, ʻaʻole hiki ke hoʻohui ʻia.Pono e mālama kaʻawale mai kēia mau mea i ka wā o ka hana a me ka hana.
15) Hiki ke hoʻohana ʻia nā mea biodegradable non-starch no ka hana ʻana i kēia mau ʻeke piha degradable: ʻeke kūʻai, ʻeke ʻeke, ʻeke ʻōwili, ʻeke ʻōpala, ʻeke palahalaha, ʻeke lima, ʻeke ʻeke lima, ʻeke meaʻai, ʻeke lima, ʻeke ʻeke. , Nā ʻeke ʻōpala holoholona, ʻeke feces pet, ʻeke ʻōpala kīhini, ʻeke paʻa ponoʻī, ʻeke lole, ʻeke ʻeke, mulch mahiʻai, kiʻiʻoniʻoni, mīkina lima, etc.
