Pehea ka hana ʻana o ka Lole RPET?

ʻO ka RPET he polyethylene terephthalate i hana hou ʻia, he mea pili kaiapuni.

Hana ʻia ke kaʻina hana o RPET mai nā fiber polyester i hoʻolei ʻia, e like me nā ʻōmole palaka ʻōpala. ʻO ka mea mua, e hoʻomaʻemaʻe pono i ka ʻōpala a wehe i nā haumia. A laila e ʻoki a wela e hoʻololi i nā ʻāpana liʻiliʻi. A laila, hoʻoheheʻe ʻia nā ʻāpana a hoʻōla hou ʻia, hoʻohui ʻia ka pauka kala, a hoʻopololei ʻia a hoʻomaʻemaʻe ʻia ma o ka mīkini wili fiber e hana i nā fibers RPET.

Hiki ke hoʻokaʻawale ʻia ka hana ʻana o nā pālule rPET i ʻehā mau loulou nui: ka hana hou ʻana i nā mea maka → hoʻōla hou i ka fiber → ulana lole → ka hoʻoponopono ʻana i ka mākaukau.

1. Hoʻihoʻi hou a me ka hoʻoponopono mua ʻana

• ʻOhi ʻōmole palaki: E hōʻiliʻili i nā ʻōmole PET ʻōpala ma o nā wahi hana hou ʻana o ke kaiāulu, nā hale kūʻai kūʻai hoʻihoʻi logistic a i ʻole nā ​​ʻoihana hoʻomaʻamaʻa ʻoihana (ma kahi o 14 miliona mau tona o nā ʻōmole PET e hana ʻia i kēlā me kēia makahiki, a he 14% wale nō o ia mea i hana hou ʻia).

• Hoʻomaʻemaʻe a me ka ʻoki ʻana: Hoʻokaʻawale ʻia nā ʻōmole plastik recycled me ka lima/mechanically (wehe i nā haumia, nā mea non-PET), wehe i nā lepili a me nā pāpale (ka hapa nui o nā mea PE / PP), holoi a wehe i nā koena wai a me nā stains, a laila e wāwahi iā lākou i nā ʻāpana 2-5cm.

2. Hoʻoulu hou i ka fiber (RPET yarn production)

• Hoʻoheheʻe heheʻe: Ma hope o ka maloʻoʻana, hoʻomehanaʻia nā'āpana PET i 250-280 ℃ e hoʻoheheʻe, e hoʻoheheʻe i ka polymer viscous.

• Ka wili ʻana: Hoʻokuʻu ʻia ka heheʻe i loko o kahi kahawai maikaʻi ma o ka pā pāpaʻi, a ma hope o ka hoʻomaloʻo ʻana a me ka hoʻōla ʻana, hana ia i kahi fiber pōkole polyester i hana hou ʻia (a i ʻole wili pololei ʻia i loko o kahi filament mau).

• Milo: hana ʻia nā kaula pōkole i ʻili RPET ma o ka hui ʻana, ka ʻili ʻana, ka ʻili koʻikoʻi, ka ʻili maikaʻi a me nā kaʻina hana ʻē aʻe (e like me ke kaʻina hana wili PET mua, akā ua hana hou ʻia ka mea maka).

3. Ka ulana lole a me ka hana lole

• Ka ulana lole: Hana ʻia ka ʻili RPET i ka lole i ulana ʻia ma o ka ulana ʻana i ka mīkini pōʻai / transverse machine (e kūlike me ke kaʻina hana o ka lole polyester maʻamau), hiki ke hana ʻia i nā ʻiʻo like ʻole e like me ka plain, pique, ribbed, etc.

• Ka hana hope a me ka humuhumu: like me nā pālule maʻamau, e like me ke kala, ʻokiʻoki, paʻi ʻana, humuhumu (ʻāʻī ʻāʻī/kaʻe), hao a me nā ʻanuʻu ʻē aʻe, a me ka hana hope ʻana i nā pālule RPET.

ʻO ka pālule RPET kahi huahana pae ʻāina maʻamau o ka "plastic recycling economy". Ma ka hoʻololi ʻana i ka palaka ʻōpala i ʻaʻahu, e noʻonoʻo ana i nā pono palekana kaiapuni a me ka waiwai kūpono.
