ʻO ka ʻokoʻa ma waena o nā ʻeke plastik biodegradable piha a me nā ʻeke plastik maʻamau

I kēia manawa ua iho mai ke kauoha palena wikiwiki no nā ʻeke plastik, ʻo nā hale kūʻai liʻiliʻi maʻamau a i ʻole nā ​​​​hale kūʻai ma ke alanui, ʻo ia nā ʻeke plastik maʻamau, pp, pe, etc. .ʻAʻole hoʻohana iki ka hoʻohui ʻana o nā mea hoʻohaʻahaʻa i kekahi mau ʻāpana palaka, a e loaʻa mau ana ka hopena o nā molekala i hoʻoheheʻe ʻia i ke kaiapuni.
Eia nō naʻe, hoʻohana kekahi mau hale kūʻai nui a me nā hale kūʻai kūʻai i nā ʻeke hiki ke hoʻopau ʻia, i hana ʻia me nā mea maka i hoʻololi ʻia e ka pbat, pla a me ka cornstarch.Hiki ke hoʻohaʻahaʻa ʻia kēia ʻano ʻeke a ʻaʻole i emi kona paʻakikī i nā ʻeke plastik maʻamau..E hoʻohaʻahaʻa loa ia i carbon dioxide a me ka wai ma kahi o 3 mau mahina ma ka lepo, a hiki ke mālama ʻia no 9 a 12 mau mahina i loko o kahi hale kūʻai maloʻo.
ʻO ka ʻokoʻa ma waena o nā ʻeke plastik biodegradable piha a me nā ʻeke plastik maʻamau

1. Nā mea likeʻole

Hana ʻia nā ʻeke plastik biodegradable piha (ʻo ia hoʻi, nā ʻeke plastik pili i ke kaiapuni) me nā PLA, PHA, PBA, PBS a me nā mea polymer ʻē aʻe.ʻO nā ʻeke plastik maʻamau maʻamau ʻaʻole hiki ke hoʻohaʻahaʻa ʻia he mau mea ʻilika ʻē aʻe e like me PE.

2. Nā kūlana hana likeʻole

Pono nā ʻeke plastik biodegradable e hoʻokō i ke kūlana aupuni GB/T21661-2008, i hōʻea i ke kūlana palekana kaiapuni.ʻAʻole pono nā ʻeke plastik maʻamau ʻole degradable e hoʻokō i kēia maʻamau.

3. He okoa ka manawa decomposition.ʻO ka maʻamau, hiki ke hoʻoheheʻe ʻia nā ʻeke plastik piha biodegradable i loko o hoʻokahi makahiki, a hiki i nā ʻeke plastik palekana palekana 'Olumepika ke hoʻomaka e decompose 72 mau lā ma hope o ka hoʻolei ʻia ʻana.He 200 mau makahiki no ka hoʻohaʻahaʻa ʻana i nā ʻeke plastik maʻamau maʻamau.

Nā pōmaikaʻi o ka hoʻohana ʻana i nā ʻeke plastik biodegradable piha

1. Ka palekana o ke kaiapuni: Hiki i ka hoʻohana ʻana i nā ʻeke plastik biodegradable piha ke hoʻemi nui i ka pilikia o ka haumia keʻokeʻo i hana ʻia e ka hiki ʻole o nā ʻeke plastik maʻamau maʻamau e decompose.

2. Hana maikaʻi loa: ʻO ka ʻeke plastik biodegradable piha ka hoʻohana ʻana i ka starch ma ke ʻano he kumu nui, ʻoi aku ka maikaʻi o ka degradation ma mua o nā mea ʻē aʻe, ʻoi aku ka lōʻihi o ka lawelawe ʻana ma mua o ka ʻeke pepa, a ʻoi aku ke kumukūʻai ma mua o ka ʻeke pepa. .

3. Ka nani a me ka maʻalahi: ʻO ka ʻeke plastik biodegradable piha a me ka ʻeke plastik maʻamau ka hana like koe wale nō nā ʻāpana a me nā mea like ʻole.Hiki iā lākou ke paʻi nani, haʻahaʻa ka nui, a hiki ke hoʻopaʻa i nā huahana he nui.

4. Recycling: ʻO ka ʻeke plastik biodegradable piha nā hiʻohiʻona o ka palupalu, ke kūpaʻa ʻana, ka foldability a me ke ʻano maikaʻi, a lōʻihi ka manawa hana hou.
