No laila, ua hoʻomohala a hana nā hui Kina i ka ʻenehana biodegradation photo-oxygen no nā mea polymer (e like me ka plastics, rubber, a me nā fibers kemika), hiki ke hoʻokō i ka biodegradation landfill a me ka compost degradation.

ʻO ka photo-oxygen biodegradable masterbatch ka ʻenehana biodegradation kokoke loa i ka hoʻohaʻahaʻa wikiwiki ʻana i ke kaiapuni kūlohelohe.Hiki i ka hoʻohui o 1% ke hoʻokō i ka hoʻohaʻahaʻa wikiwiki me ka ʻole o ka hoʻololi ʻana i nā mea, nā lako hana, nā kaʻina hana a me ka hana holoʻokoʻa o ka mea.

Eia nō naʻe, ke piʻi aʻe nei ke kumukūʻai o ka polylactic acid PLA, PBAT, PBS, PHA a me nā ʻenehana biodegradable ʻē aʻe ma ka liʻiliʻi o 100% a 200%, a ʻaʻole hiki i ka hana holoʻokoʻa ke hōʻea i ka hana o nā plastics kuʻuna, no laila nā mea, nā lako hana a me nā kaʻina hana. pono e hoololi.

Hiki ke hoʻohana ʻia ka ʻenehana biodegradation photo-oxygen biodegradation no nā kiʻiʻoniʻoni plastik e like me PE a me sarin i ka hana ʻana i ka pepa i uhi ʻia i ka meaʻai wikiwiki i ka mākeke Kina.#PE ʻōwili pepa i uhi ʻia

ʻIke loea o ka ʻenehana biodegradation photo-oxygen

ʻO ke kiʻiʻoniʻoni kiʻiʻoniʻoni kiʻi-oxidative biodegradation ʻenehana o ka hui Kina he ʻano ʻenehana hou e hoʻoheheʻe piha ʻia ma muli o ke kiʻiʻoniʻoni i hoʻolei ʻia i ke kaiapuni kūlohelohe.Hoʻolālā ʻia ka ʻenehana no ka mālama ʻana i kona ola pono ma ke ʻano he waiwai a me kona mechanical, mechanical, barrier, transparency a me nā waiwai kalepa ʻē aʻe i loko o kona pōʻai ola, a hiki i nā kiʻiʻoniʻoni plastik ke biodegrade ma lalo o nā kūlana kūlohelohe ma hope o ka hoʻolei ʻia ʻana.

ʻO ka ʻenehana ka hoʻohui ʻana i ka masterbatch biodegradable photo-oxygen biodegradable i ke kiʻiʻoniʻoni i mea e hana ai ia ma ke ʻano he kiʻiʻoniʻoni kiʻiʻoniʻoni biodegradable photo-oxygen biodegradable plastic olefin.E hoʻomaikaʻi i ka wikiwiki i hoʻokomo ʻia nā ʻātoma oxygen i loko o nā kaulahao polymer o nā polymers plastic.Ua haki ʻia nā polymers plastic i loko o nā mea molekala liʻiliʻi i loko o kahi kaiapuni aerobic, a laila decomposed e nā microorganism ma nā wahi āpau i ke kaiapuni kūlohelohe.#Pepa i uhi ʻia i lalo o ka pepa

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana hoʻohaʻahaʻa o nā kiʻiʻoniʻoni plastik me ka hoʻohana ʻana i ka ʻenehana biodegradation photo-oxygen i ʻelua mau pae.
ʻO ka pae mua: ʻO ka kiʻiʻoniʻoni i hoʻohui ʻia me ka photo-oxygen biodegradable masterbatch e pane me ka oxygen i ka lewa, e hoʻoulu ai ka mea hoʻohui i ke kaulahao kalapona o ka polymer, a ua hoʻoheheʻe ʻia ka iwi kuamoʻo kalapona e hana i nā ʻāpana molekala me kahi mole mole pili. liʻiliʻi ma mua o 10,000 a i ʻole ka liʻiliʻi ( Ke manaʻoʻiʻo nei nā ʻepekema ma ʻEulopa a me Iapana e hiki ke ale ʻia e nā microorganisms me ka nui o ka molecular pili ma lalo o 400,000).

I kēia pae, he hana abiotic ka hoʻohaʻahaʻa ʻana, e hāpai ana i ka hoʻokomo ʻana o nā ʻātoma oxygen i loko o ka iwi kuamoʻo kahi e haki ai ka polymer e hana i nā pūʻulu hana like ʻole (e like me ka carboxylic acids, esters, aldehydes, a me nā waiʻona).

Hoʻololi ka polymer molecular kiʻekiʻe mai kahi kaulahao macromolecule hydrophobic i kahi kaulahao liʻiliʻi liʻiliʻi hydrophilic, kahi e maʻalahi ai nā ʻāpana o ke kaulahao molekala e hoʻopau ʻia a ʻeli ʻia e ka bacteria.# Pepa kīʻaha pepa mea maka

ʻO ka lua o ka pae: ʻo nā microorganisms maʻamau (bacteria, fungi a me nā algae) ma ke ʻano e hoʻoheheʻe i ka kiʻiʻoniʻoni ma ke ʻano he kumu meaʻai, a hope loa e decompose i carbon dioxide, ka wai a me ka biomass.Ua kapa ʻia ka hoʻohaʻahaʻa ʻana i kēia kaʻina hana biodegradation.

Ho'āʻo a me nā kūlana

Inā ma ka lewa a i ʻole ma ka hale hana, hiki i ka helu degradation o kēia ʻenehana ke piʻi ma mua o 60%.I koʻu ʻāina ʻāina ʻo GB/T 20197-2006 a me GB/T 19277.1-2011, ʻo nā koi hoʻāʻo kiʻekiʻe loa no ka biodegradation rate he 60%.

I ka mokuʻāina ʻo Laboratory, no nā kiʻiʻoniʻoni me ka mānoanoa o lalo o 15 μm, hiki iā lākou ke komo i ka pae biodegradation ma hope o ka hoʻohālikelike ʻana i 3 mau mahina o ka ʻelemakule maoli.Hiki i ka ʻelemakule simulated ke koho i ka ʻelemakule UV a i ʻole ka ʻelemakule kukui xenon.

Ke komo nei i ka pae biodegradation, ʻo ka maʻamau degradation polyolefin kiʻekiʻe loa ma ka honua (PAS 9017: 2020) koi i ka helu degradation ʻoi aku ma mua o 90% i loko o 730 mau lā, ʻoi aku ka kiʻekiʻe ma mua o ke kūlana aupuni ma koʻu ʻāina.

ʻO ka pae ʻenehana o ka ʻenehana biodegradation photo-oxidative o ka kiʻiʻoniʻoni plastik i ʻoi aku ma mua o ka maʻamau o ke aupuni, ʻo ia ka laina me ka maʻamau degradation polyolefin kiʻekiʻe loa i ka honua (PAS 9017: 2020).

Ma hope o ka hoʻohui ʻana i ka masterbatch biodegradable photo-oxygen i loko o nā resins plastik e like me PE a me sarin, nā huahana i hana ʻia he mau waiwai biodegradable, a hiki i kā lākou 180-lā biodegradation rate hiki ke hiki i 60%, e hoʻokō ana i ka maʻamau maʻamau GB / T 38082- 2019 koi ʻia biodegradation rate.Hiki ke hoʻopau piha ʻia ma lalo o nā kūlana o ka wehe ʻana i ka ea, ka ʻāina a i ʻole ka hoʻopuehu aerobic.# Pepa pepa i uhi ʻia e PE

Hiki i ka ʻenehana biodegradation photo-oxygen ke hele i ka hoʻāʻo ʻana o nā kūlana aupuni Kina: GB/T 20197-2006, GB/T 19277.1-2011, GB/T 38082-2019.E like me ke kulekele kalapona ʻelua a me ke akeakamai.

Ke koho ʻana i nā ala ʻenehana Biodegradation no nā uhi like ʻole

ʻOi aku ka maikaʻi o ka uhi ʻana o EVA a me ka uhi PP no ka ʻenehana biodegradation o ka hui Kina (anaerobic + marine), ʻoiaʻiʻo, hiki ke hoʻohana pū ʻia ka ʻenehana photo-oxygen biodegradation o ka hui Kina.

ʻOi aku ka maikaʻi o ka resin sarin, LLDPE, LDPE a me nā ʻāpana ʻē aʻe no ka ʻenehana biodegradation photo-oxygen o nā hui Kina.ʻOiaʻiʻo, hiki nō ke hoʻemi i ka wela heheʻe ma lalo o 310 °C e hoʻomaʻamaʻa i ka hoʻohana ʻana i ka ʻenehana biodegradation (anaerobic + marine).#Nanning Dihui Paper Products Co., Ltd.
