ʻO nā mea plastik maʻamau a me ka hoʻohana ʻana

I kēia lā, e hoʻomau wau e lawe iā ʻoe e hoʻomaopopo i nā inoa a me ka hoʻohana ʻana i kekahi mau mea maʻamau maʻamau i ke ola o kēlā me kēia lā, a kōkua iā ʻoe e hoʻokaʻawale a hoʻokaʻawale i ke ola o kēlā me kēia lā.

PVC: ʻO PVC paha kekahi o nā mea plastik i hoʻohana nui ʻia, mai nā puka plastik a me nā puka makani i ke ola o kēlā me kēia lā i nā paipu wai, nā auwai, nā kāmaʻa, ka insulation cable, nā mea pāʻani, nā huahana i hoʻoheheʻe ʻia, nā kino ʻālohilohi, nā huahana extruded, a me ka hui aniani. , nā kāleka hōʻaiʻē, a me nā mea ʻē aʻe, loaʻa kona ʻano i nā wahi a pau, a ʻo ka mea PVC kekahi o nā mea ʻilika maʻalahi.He maʻalahi, maʻalahi ke kala, he ʻano paʻakikī ke koho mai, hiki ke hoʻokuʻu ʻia, hoʻolei ʻia a hoʻoheheʻe ʻia, hiki ke hoʻoikaika ʻia me ka fiber aniani, hiki ke mālama i kona mau hiʻohiʻona i nā haʻahaʻa haʻahaʻa, hiki ke paʻi ʻia, hana hou. a he kū'ē maika'i ke kū'ē i ka waimaka a me ka abrasion, maika'i ka lā a me ka wai kai kū'ē, maika'i ka aila a me ke kinikini.

PU: He mea ʻili ka PU, hiki iā ia ke hanu a kikoo, akā hiki ke hoʻoheheʻe ʻia i nā ʻano o nā mānoanoa like ʻole.Ua hoʻohana mua ʻia kēia mau hiʻohiʻona i nā ʻoihana lapaʻau a me nā ʻoihana plastik, a ua hoʻohana ʻia e like me nā mea cushion no nā maʻi ma nā halemai.He maikaʻi ka puʻupuʻu puʻupuʻu, ea permeability, ikaika hoʻihoʻi ikaika, maʻalahi e hui pū me nā mea hoʻonaninani, hoʻoheheʻe ikaika i ka haʻalulu, kaomi ikaika absorption, hiki ke hoʻololi i ka paʻakikī, elasticity kiʻekiʻe, ʻaʻohe mae, paʻa, ʻaʻole hoʻonāukiuki i ka ʻili, a hiki ke hoʻolei ʻia.

PC: Ma ke ʻano he mea hou, hoʻohana ʻia ʻo PC i kēia huahana e wehewehe i kahi mea maʻamau a me ke ʻano.ʻAʻole hoʻohana kēia huahana i ka lāʻau, akā ua hana ʻia i kahi mea hou i kūpono loa no kēia hana.He paʻakikī ka PC e like me nā polymers ʻē aʻe, akā māmā ke kaumaha, a hiki ke hāʻawi i nā ʻano kala like ʻole a me nā hopena ma hope o ka hoʻoponopono ʻana.Ma ke ʻano he lālā o ka ʻohana thermoplastic ʻōpio, ʻo PC, e like me nā mea plastik ʻē aʻe, ua ʻike ʻole ʻia e General Electric i nā makahiki 1950.Uaʻikeʻia kēia mea no ka māmā a me ka ikaika nui, a hoʻohana pinepineʻia e pani i ke aniani i nā noi e like me ka māmā a me ka maʻalahi.Hiki iā ia ke hāʻawi i kahi moʻo o ke kala kala, nā kaʻina hana maʻalahi a me ke kūpaʻa hopena maikaʻi loa.Hiki iā ia ke hāʻawi i nā hopena hiʻohiʻona piha, translucent a opaque.ʻOiai i nā wela kiʻekiʻe, ʻoi aku ka ikaika o kona kūpaʻa dimensional, kiʻekiʻe ka pale ʻana i ka mahana a hiki i 125C, pale ahi, ʻo ka pale radiation ka lōʻihi, recyclable a me nā mea ʻawaʻawa.

He ʻokoʻa nā mea plastik, haʻahaʻa ke kumu kūʻai, a lawe mai i ka ʻoluʻolu nui i ke ola kanaka.Me ka ʻike maʻamau o nā mea, hiki iā ʻoe ke koho maikaʻi i nā pono o kēlā me kēia lā i kou ola.
