Ke ʻimi nei ʻoe i kahi mea ʻē aʻe i ka plastic a me ka hoʻopili ʻana i ka ʻaila?Ke neʻe nui nei ka mākeke o kēia lā i nā huahana biodegradable a me nā huahana eco-friendly i hana ʻia mai nā kumuwaiwai hou.

Ua lilo koke nā huahana PLA i hoʻokahi o nā koho biodegradable kaulana loa i ka mākeke.Ua ʻike ʻia kahi noiʻi 2017 ʻo ka hoʻololi ʻana i nā plastics-based petroleum me nā plastics-based bio-based hiki ke hōʻemi i ka hoʻokuʻu ʻia ʻana o ke kinoea hoʻomehana honua ma 25%.

He aha ka PLA?

ʻO ka PLA, a i ʻole polylactic acid, ua hana ʻia mai kekahi kōpaʻa fermentable.Hana ʻia ka hapa nui o ka PLA mai ke kulina no ka mea ʻo ka kulina kekahi o nā mea koʻikoʻi loa a loaʻa i ka honua.Eia nō naʻe, ʻo ke kō, ka aʻa tapioka, ka ʻuʻuku, a me ka pulp beet sugar kekahi mau koho ʻē aʻe.

E like me ka nui o nā mea pili i ke kemika, paʻakikī loa ke kaʻina hana o ka hana ʻana i ka PLA mai ka kulina.Eia nō naʻe, hiki ke wehewehe ʻia i kekahi mau ala pololei.

Pehea e hana ʻia ai nā huahana PLA?

ʻO nā ʻanuʻu kumu e hana ai i ka polylactic acid mai ka kulina penei:

1. Pono e ho'ololi 'ia ka mākiko kulina mua i kō ma o ke ka'ina hana i kapa 'ia ka wili pulu.ʻO ka wili pulu e hoʻokaʻawale i ka starch mai nā kernels.Hoʻohui ʻia ka ʻakika a i ʻole nā ​​enzyme ke hoʻokaʻawale ʻia kēia mau ʻāpana.A laila, hoʻomehana ʻia lākou e hoʻololi i ka mākiko i dextrose (aka sugar).

2. A laila, ua fermented ka dextrose.ʻO kekahi o nā ʻano fermentation maʻamau e pili ana i ka hoʻohuiLactobacillusbacteria i ka dextrose.ʻO kēia ka mea e hana ai i ka waikawa lactic.

3. A laila, hoʻololi ʻia ka ʻakika lactic i lactide, he dimer ʻano apo o ka waikawa lactic.Hoʻopili pū kēia mau molekala lactide e hana i nā polymers.

4. ʻO ka hopena o ka polymerization he mau ʻāpana liʻiliʻi o ka polylactic acid plastic plastic i hiki ke hoʻololi ʻia i ʻāpanaNā huahana plastik PLA.

Nā pōmaikaʻi o ka ʻeke meaʻai:

• ʻAʻole like ko lākou ʻano hoʻohui kemika ʻino e like me nā huahana kumu ʻaila
• E like me ka ikaika e like me nā plastics maʻamau
• Palekana-palekana
• Hiki i nā kīʻaha ke mālama i nā mahana a hiki i 110°F (hiki i nā mea PLA ke mālama i nā mahana a hiki i 200°F)
• Non-toxic, carbon-neutral, a 100% hiki ke hana hou

Hoʻohana ʻia ka PLA, kūpono ke kumu kūʻai, a paʻa.ʻO ka hoʻololi ʻana i kēia mau huahana he hana koʻikoʻi ia i ka hōʻemi ʻana i ka wāwae kalapona o kāu ʻoihana meaʻai.

Hiki i ka hui JUDIN ke hāʻawi i ka uhi PLAkīʻaha pepa, pahu pepa,ipu salakeke pepaa me nā mea ʻoki ʻoki PLA,PLA kīʻaha ʻālohilohi.
