Mai ka waena -kenekulia 20, ua lilo koke nā huahana plastik i mea waiwai nui i ka nohona o kēia wā ma muli o ko lākou mau pono hana. ʻO kā lākou mau waiwai māmā, lōʻihi, kumu kūʻai -makemake, a maʻalahi hoʻi-e hana i mea hiki ʻole ke hoʻololi iā lākou i nā pā he nui.
ʻO ka mea mua, ʻo ke ʻano māmā o nā huahana plastik e hōʻemi nui i ka lawe ʻana a me nā kumukūʻai mālama. Ke hoʻohālikelike ʻia me nā mea kahiko e like me ka metala a me ke aniani, ʻoi aku ka haʻahaʻa o ka plastics, e hōʻemi nui ana i ke kaumaha o ka huahana a, no laila, ka hoʻohana ʻana i ka ikehu. He ʻoiaʻiʻo kēia i nā ʻoihana e like me ka automotive a me ka mokulele, kahi i hoʻohana nui ai ka hoʻohana ʻana i nā plastics i ka hoʻomaikaʻi maikaʻi ʻana i ka wahie. Eia kekahi, hiki ke ho'ohana 'ia no ka wā lō'ihi -i loko o nā kaiapuni 'o'ole'a, me ka 'ole o ka 'ele a me ka ho'ouka 'ana i ke kino, no laila kūpono ia no nā hana ko'iko'i e like me nā ipu kemika a me ka paipu.
ʻO ka lua, hāʻawi nā huahana plastic i ka plasticity maikaʻi loa a me ka hiki ke hoʻololi. Ma o nā kaʻina hana e like me ka injection molding, blow molding, a me ka extrusion, hiki ke hana ʻia nā plastics i nā ʻano like ʻole a me nā nui e hoʻokō ai i nā pono o nā ʻoihana like ʻole. Mai nā mea i kēlā me kēia lā e like me nā ʻeke plastik a me nā mea ʻokiʻoki i nā mea lapaʻau paʻakikī a me nā hale mea uila, hiki ke hoʻololi ʻia nā plastics. Eia kekahi, ʻoi aku ka maʻalahi o ka plastics i ka hana ʻana a ʻoi aku ka maikaʻi i ka wā i hana ʻia ma ke ʻano nui, e hiki ke loaʻa iā lākou i nā miliona o nā hale.
Loaʻa i nā plastik nā waiwai uila a me ka wela wela, e pāʻani ana i kahi hana koʻikoʻi i nā mea uila a me ka insulation hale. Hiki ke pani i kekahi mau mea metala, e ho'okō ana i nā koi ikaika -ki'eki'e no ka ikaika a me ka lō'ihi, e like me nā mea ka'a a me nā mea aerospace.
ʻOiai ka nui o ka hopohopo e pili ana i ka plastics, ʻo ka holomua ʻenehana ke alakaʻi nei i ka hoʻomohala ʻana i nā hopena biodegradable a me recyclable. ʻO ka holoʻokoʻa, noho mau ka plastics i mea koʻikoʻi i ka ʻoihana hou a me ke ola o kēlā me kēia lā, mahalo i kā lākou versatility, affordability, a me ka hoʻohana.
