Eia ka pane iā ʻoe. ʻO ka emi ʻana o ka ʻelepani ʻelepani i ka hopena o ke kenekulia 19 a me ka hoʻomaka ʻana o ke kenekulia 20, me ka hoʻomohala ʻana o ka hahai holoholona nui a me ke kālepa niho, ua hoʻokumu ʻia kahi pono no nā mea ʻē aʻe. ʻO ka hopena, ua hoʻomaka nā mea noiʻi he nui e ʻimi i nā mea hiki ke hoʻohana ʻia no ka hana ʻana i nā ʻili paʻakikī a maʻalahi o ka dentine artificial. Ua alakaʻi ʻia kēia mau hopena i ka hana ʻana o nā plastics.
ʻO ka hoʻomohala hou o nā plastics

He aha ka mea hou loa i ka makahiki 1970, ʻo nā ʻeke kūʻai ʻilika i kēia manawa he huahana puni honua, me ka trillion o lākou i hana ʻia i kēlā me kēia makahiki ma kēlā me kēia kihi o ka honua.
Ka nānā 'ana i nā huahana plastic o kā mākou hui
Nui nā ʻano o ka plastic, a ʻo kā mākou hui he mea hana i nā ipu plastik no nā mea hoʻonaninani, ʻoihana, nā mea uila, nā mea pāʻani puhi, nā waiwai i hoʻohana ʻia i kēlā me kēia lā e hoʻohui i ka hoʻomohala ʻana, hoʻolālā a kūʻai aku. ka pāpale omole, ke poʻo pump a me nā huahana plastik ʻē aʻe. Aia i loko o ka hoʻokele waiwai i kūkulu ʻia ʻo Pearl River Delta, hauʻoli mākou i ka lawe ʻana i ka ʻāina a me ka wai, hoʻopaʻa i nā lako hana kiʻekiʻe egplastic molding machines, nā mīkini puhi ʻōmole, nā mīkini paʻi kiʻi ʻoniʻoni, nā mīkini gilding, a ua hoʻonui i ka nui o ka hana.
Hāʻawi mākou i nā lawelawe ʻoihana hoʻokahi me ka hoʻolālā huahana, hoʻomohala, puhi, paʻi siliki, lepili, gilding, sanding a me ka lawe ʻana. ʻO ka mana hana o kā mākou mīkini pahu pahu pahu kiʻekiʻe mai 10ml a 5000ml, hiki ke hoʻokō i nā koi o nā mea hoʻohana. Ua hana mua ʻia ka plastic no ka pale ʻana i nā elepani, akā i kēia manawa ua hoʻopōʻino ʻole ʻia ka plastic i nā holoholona, ke kaiapuni a me nā kānaka. Kokoke ka poino i hanaia e ka plastic
