2026-01-30

Ke koho mākou i kahi ʻōmole shampoo i hoʻohana pinepine ʻia, aia kahi lepili PET ma lalo o ka ʻōmole, e hōʻike ana he ʻōmole PET kēia huahana. Hoʻohana nui ʻia nā ʻōmole PET i ka ʻoihana mālama pilikino a he nui ka nui o ka mana. ʻO nā ʻōmole PET he mau ipu plastik i loaʻa ma ka hana ʻana i nā mea plastik PET ma o nā ʻano hana hoʻokahi a ʻelua paha. Loaʻa i ka plastik PET nā ʻano o ka māmā, ʻike maopopo loa, a kūpaʻa i ka hopena a me ka wāwahi.

ʻO PET, a i ʻole polyethylene terephthalate, ua ʻike ʻia hoʻi ʻo polyester. ʻO kona inoa Pelekania ʻo Polyethylene Terephthalate, i hana ʻia e ka hopena polymerization (condensation) o ʻelua mau mea maka kemika: terephthalic acid (PTA) a me ethylene glycol (EG). ʻO nā preforms he mau mea i hoʻoheheʻe ʻia i ka injection. Ma ke ʻano he huahana semi-finished waena no ka hoʻolōʻihi biaxial ma hope a me ka hoʻoheheʻe ʻana i ka puhi, ua hoʻohālikelike ʻia ka ʻāʻī o ka preform i ka wā o ke kahua hoʻoheheʻe ʻana i ka injection, a ʻaʻole e loli kona nui i ka wā o ka hoʻomehana ʻana a me ka hoʻolōʻihi / hoʻoheheʻe ʻana i ka puhi. ʻO ka nui, ke kaumaha, a me ka mānoanoa o ka paia o ka preform nā mea e pono ai ke nānā pono i ka wā o ke kaʻina hana hoʻoheheʻe ʻana o ka ʻōmole.

I ka hoʻomākaukau ʻana i nā ʻōmole i hoʻoheheʻe ʻia, hoʻokomo mua ʻia nā ʻāpana PET i loko o ka preform. Pono ʻia ʻaʻole e kiʻekiʻe loa ka nui o nā mea hana hou ʻia (emi ma mua o 5%), a ʻaʻole e ʻoi aku ka manawa hana hou ʻana ma mua o ʻelua. ʻAʻole pono e haʻahaʻa loa ke kaumaha molekala a me ka mānoanoa (kaumaha molekala 31,000 - 50,000, mānoanoa kūloko 0.78 - 0.85 cm³/g). Wahi a ke Kānāwai Palekana Meaʻai Lahui, ua pāpā ʻia ka hoʻohana ʻana i nā mea hana hou ʻia no ka ʻōpala meaʻai a me nā lāʻau lapaʻau. Pono e mālama ʻia nā preform i hoʻoheheʻe ʻia no nā hola he 24 ma mua o ka hoʻohana ʻana. Pono e mālama ʻia nā preform i hoʻohana ʻole ʻia ma hope o ka hoʻomehana ʻana no nā hola he 48 ma mua o ka hoʻomehana hou ʻana. ʻAʻole pono e ʻoi aku ka manawa mālama o nā ʻōmole ma mua o ʻeono mahina. ʻO ke ʻano o ka preform e hilinaʻi nui ʻia i ka maikaʻi o ka mea PET, no laila pono e koho i nā mea i maʻalahi ke hoʻopiha a hana, a e hoʻomohala i kahi kaʻina hana hoʻoheheʻe preform kūpono. Ua hōʻike ʻia nā hoʻokolohua he maʻalahi ke puhi ʻia nā preforms i hana ʻia mai nā mea maka i lawe ʻia mai me ka mānoanoa like ma mua o nā mea i hana ʻia mai nā mea maka kūloko. Eia nō naʻe, no ka pūʻulu like o nā preforms, pono paha nā lā hana like ʻole i nā kaʻina hana puhi ʻokoʻa. ʻO ke ʻano o ka preform e hoʻoholo ai i ka paʻakikī o ke kaʻina hana puhi. ʻO nā koi no ka preform he maʻemaʻe, transparency, ʻaʻohe haumia, ʻaʻohe kala, ka lōʻihi kūpono o ka injection, a me kahi halo a puni.

He mau kala paʻa ka hapa nui o nā ʻōmole mea PP a me PE, ʻoiai ʻo nā mea PETG, PET, a me PVC he moakāka a i ʻole kala ʻia me ka helehelena moakāka a translucent, a ʻaʻole i hoʻohana pinepine ʻia nā kala paʻa. Hiki ke pena ʻia nā ʻōmole mea PET. Aia kahi kiko convex ma lalo o ka ʻōmole i hoʻoheheʻe ʻia, ʻoi aku ka mālamalama ma lalo o ka mālamalama. Aia ka lalo o ka ʻōmole i hoʻoheheʻe ʻia me ka injection-blow i kahi laina hoʻopaʻa. ʻO nā mea pono nui no nā ʻōmole i hoʻoheheʻe ʻia me nā mea pani o loko (hoʻohana pinepine ʻia no nā mea PP a me PE), nā pāpale o waho (hoʻohana pinepine ʻia no PP, ABS, a me acrylic, a loaʻa pū kekahi i nā electroplated, electro-galvanized, a me nā mea pena ʻia, hoʻohana pinepine ʻia no nā ʻōmole toner), nā uhi poʻo pamu (hoʻohana pinepine ʻia no ka essence a me ka lotion), nā pāpale flip, a me nā pāpale snap (hoʻohana nui ʻia i nā laina kemika o kēlā me kēia lā).
