E pili ana i nā mea plastik, aia nā ʻano koho like ʻole ma ka mākeke e koho ai. Loaʻa i kēlā me kēia mea kona mau pono pono'ī a me nā noi, no laila he mea nui e hoʻomaopopo i nāʻokoʻa a koho i nā mea kūpono no kāu mau pono kiko'ī. Ma kēia pou blog, e kūkākūkā mākou i ka ʻokoʻa ma waenaPepa PPa me ka papa PP, ʻelua mau mea plastik kaulana i hoʻohana nui ʻia i nā ʻoihana like ʻole.
Hana ʻia ka pepa PP a me ka papa PP me ka polypropylene, kahi polymer thermoplastic me nā waiwai maikaʻi loa. ʻIke ʻia no kona kūpaʻa ʻana i ka luhi a me ke kūpaʻa wela maikaʻi loa, kūpono ka polypropylene no nā noi e koi ana i ka lōʻihi a me ke kūpaʻa wela kiʻekiʻe.
ʻO ka ʻokoʻa nui ma waena o ka pepa PP a mepapa PPaia i ko lakou mau waiwai kino.Pepa PPhe pepa ʻilika lahilahi me ka ikaika tensile kiʻekiʻe a me ka ikaika o ka ʻili. Hoʻohana pinepine ʻia lākou no ka hoʻopaʻa ʻana no ka mea hāʻawi lākou i ka pale maikaʻi loa a kūʻē i ka lole a me ka oxidation. Ua ʻike ʻia nā pepa PP no ko lākou kūpaʻa kiʻekiʻe kiʻekiʻe, e kūpono iā lākou no nā noi i ka ʻoihana kemika.
Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka mānoanoa o ka papa PP ma mua o ka pepa PP. Hoʻohana pinepine ʻia lākou i nā noi e koi ana i ka ikaika kiʻekiʻe a me ka paʻakikī, e like me nā hōʻailona, hōʻike a me nā mea hana. ʻO ka papa PP hoʻi ke kūlou i ka luhi luhi a me ka pale wela maikaʻi, e like me ka pepa PP.
ʻOiai ʻo ka pepa ʻelua PP a mepapa PPloaʻa i kekahi mau hiʻohiʻona maʻamau, pono e hoʻolohe i nā ʻokoʻa i kā lākou mau palena. He mea maʻalahi ka pepa PP i ka haʻahaʻa haʻahaʻa a ʻaʻohe pale i ka wā. He mea paʻakikī nō hoʻi lākou no nā varnish a me nā glues, ʻaʻole hiki ke welded me ke alapine kiʻekiʻe. Ma ka ʻaoʻao ʻē aʻe, loaʻa i nā panela PP kēia mau palena a me nā pilikia i ka pena ʻana a me ka hoʻopaʻa ʻana.
Ke koho nei ma waena o ka pepa PP a me ka papa PP, he mea nui e noʻonoʻo i kāu mau koi kikoʻī a me ka noi i manaʻo ʻia. Inā makemake ʻoe i kahi mea lahilahi a maʻalahi me ke kūpaʻa kemika maikaʻi loa, ʻo ka pepa PP ke koho maikaʻi loa. Ma ka ʻaoʻao ʻē aʻe, inā makemake ʻoe i kahi mea ikaika me ka ikaika kiʻekiʻe a me ka paʻakikī,papa PPe ʻoi aku ka kūpono.
I ka pōkole, ʻeluaPepa PPa ʻo ka papa PP he mau mea palaka maʻamau me kā lākou mau waiwai ponoʻī a me nā noi. ʻOiai kaʻana like lākou i nā waiwai maʻamau, e like me ke kū'ē ʻana i ka luhi a me ka wela, pono e noʻonoʻo i ko lākou mau palena i ka wā e hoʻoholo ai. Ma ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o ka pepa PP a me ka papa PP, hiki iā ʻoe ke hana i kahi koho ʻike a koho i nā mea kūpono loa no kāu mau pono kikoʻī.
