1. Nānā o ke kaulahao ʻoihana:
ʻO ka inoa piha o ka polylactic acid he poly lactic acid a i ʻole poly lactic acid. ʻO ia kahi mea polyester molecular kiʻekiʻe i loaʻa ma ka polymerization me ka lactic acid a i ʻole ka lactic acid dimer lactide e like me ka monomer. Aia ia i kahi mea molekala kiʻekiʻe synthetic a loaʻa nā hiʻohiʻona o ke kumu biological a me ka degradability. I kēia manawa, ʻo ka polylactic acid he plastic biodegradable me ka ʻoihana ʻoi loa, ka mea nui loa a me ka hoʻohana nui ʻia i ka honua. ʻO ke kiʻekiʻe o ka ʻoihana polylactic acid nā ʻano kumu kumu kumu āpau, e like me ka kulina, ke kō, ke kō, ke kō, a me nā mea ʻē aʻe, ʻo ka waena waena ka hoʻomākaukau ʻana i ka waika polylactic, a ʻo ka lalo ka mea nui o ka noi ʻana o ka polylactic acid, me ka mālama ʻana i ke kaiapuni. papaʻaina, hoʻopili palekana kaiapuni, etc.
2. ʻOihana i luna
I kēia manawa, ʻo ka mea maka o ka ʻoihana polylactic acid home he lactic acid, a ʻo ka lactic acid ka mea i hoʻomākaukau nui ʻia mai ka palaoa, ke kō, ke kō a me nā huahana mahiʻai ʻē aʻe. No laila, ʻo ka ʻoihana kanu mea kanu i hoʻomalu ʻia e ka kulina ka ʻoihana upstream o ka polylactic acid industrial chain. Mai ka hiʻohiʻona o ka hua kulina o Kina a me ka wahi kanu, e hiki aku ana ka hua kanu kulina o Kina i ka 272.55 miliona tons ma 2021, me ka nui nui, a ua paʻa ka wahi kanu ma 40-45 miliona mau ʻeka no nā makahiki he nui. Mai ka hoʻolako ʻana i ke kulina i ka wā lōʻihi ma Kina, hiki ke manaʻo ʻia e kūpaʻa ka lako kulina i ka wā e hiki mai ana.
No nā mea waiwai ʻē aʻe i hiki ke hoʻohana ʻia no ka hana ʻana i ka waikawa lactic, e like me ke kō a me ke kō, ʻo ka huina o Kina i ka makahiki 2021 he 15.662 miliona tons, ʻoi aku ka haʻahaʻa ma mua o nā makahiki i hala, akā aia nō i ka pae maʻamau. A ke ʻimi nei nā ʻoihana a puni ka honua i nā ala hou e hoʻomākaukau ai i ka lactic acid, e like me ka hoʻohana ʻana i ke kumu kō i loko o nā fila lāʻau e like me ka mauʻu a me ka sawdust e hoʻomākaukau ai i ka lactic acid a i ʻole ke ʻimi ʻana i ke ʻano o ka hoʻohana ʻana i ka methane e hana i ka lactic acid. Ma ka holoʻokoʻa, ʻo ka hoʻolako ʻana i ka ʻoihana upstream o ka polylactic acid e paʻa mau i ka wā e hiki mai ana.
3. ʻoihana waena
Ma ke ʻano he mea biodegradable holoʻokoʻa, hiki i ka polylactic acid ke hoʻopau i ka waiwai maka i loko o ka ʻōnaehana regeneration a me recycling, nona nā pono i loaʻa ʻole i nā mea waiwai. No laila, ke hoʻonui nei ka hoʻohana ʻana o ka polylactic acid i ka mākeke home. ʻO ka hoʻohana ʻana i ka home ma 2021 he 48071.9 tons, kahi hoʻonui o 40% makahiki-ma-makahiki.
Ma muli o ka haʻahaʻa haʻahaʻa o ka polylactic acid ma Kina, ʻoi aku ka nui o ka nui o ka waika polylactic i Kina ma mua o ka nui o ka lawe ʻana aku. I nā makahiki i hala iho nei, ua piʻi wikiwiki ka nui o ka lawe ʻana mai o ka polylactic acid e ka noi home. I ka makahiki 2021, hiki i ka lawe ʻana mai o ka polylactic acid i 25294.9 tons. ʻO ka hoʻokuʻu ʻana i ka waika polylactic i holomua nui i ka makahiki 2021, a hiki i 6205.5 tons, hoʻonui i ka makahiki i ka makahiki o 117%.
Hōʻike e pili ana: hōʻike e pili ana i ka nānā ʻana i ke ʻano hoʻomohala a me ka wānana ʻana i ka hoʻomohala ʻana o ka ʻoihana huahana polylactic acid o Kina mai 2022 a 2028 i hoʻopuka ʻia e Zhiyan consulting
4. ʻOihana lalo
I nā noi lalo, ua hoʻohana ʻia ka polylactic acid i nā kula he nui me kona biocompatibility kūʻokoʻa a me ka biodegradability. I kēia manawa, ua hoʻohana nui ʻia i ka hoʻopili ʻana i ka pae kiʻekiʻe o ka meaʻai, ka papa ʻaina, ka ʻeke ʻeke kiʻiʻoniʻoni a me nā huahana ʻē aʻe a me nā māla. No ka laʻana, hiki ke hoʻohaʻahaʻa loa ʻia ka kiʻi ʻoniʻoni i hana ʻia me ka polylactic acid a nalowale ma hope o ka hōʻiliʻili ʻana i nā mea kanu, ʻaʻole ia e hōʻemi i ka nui o ka wai a me ka momona o ka lepo, akā e pale pū i nā uku hana a me nā hana e pono ai no ka hoʻihoʻi ʻana o ʻO ke kiʻiʻoniʻoni plastik, ʻo ia ke ʻano maʻamau o ka hoʻomohala ʻana i ka kiʻiʻoniʻoni plastik ma Kina i ka wā e hiki mai ana. ʻO ka wahi i uhi ʻia e ka kiʻiʻoniʻoni plastik ma Kina ma kahi o 18000 mau ʻeka, a ʻo ka hoʻohana ʻana i ka kiʻiʻoniʻoni plastik ma 2020 he 1357000 tons. Ke hiki ke hoʻolaha ʻia ke kiʻi ʻoniʻoni degradable, ʻo ka ʻoihana polylactic acid kahi wahi nui no ka hoʻomohala ʻana i ka wā e hiki mai ana.
