I ka hiki ʻana i nā kiʻiʻoniʻoni plastik, ʻelua mau koho kaulana i ka mākeke:HDPE(High-Density Polyethylene) aLDPE(Polyethylene Haʻahaʻa Haʻahaʻa).Hoʻohana maʻamau ʻia nā mea ʻelua i ka hoʻopili ʻana, ka mahiʻai, a me nā ʻoihana kūkulu.Eia nō naʻe, manaʻo nui nā mea kūʻai a me nā ʻoihana ʻoi aku ka maikaʻi ma waena o HDPE a me LDPE.Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa ma waena o nā mea ʻelua a kūkākūkā i kā lākou pono a me nā hemahema.
ʻO ka mea mua, e nānā kākou i ka LDPE.ʻO ka LDPE he mea maʻalahi a māmā hoʻi i hoʻohana mau ʻia i ka hana ʻana i nā kiʻi ʻoniʻoni ʻiʻo lahilahi a ʻōlohi.Hoʻohana pinepine ʻia ʻo LDPE no ka hoʻopaʻa ʻana, e like me ka hana ʻana i nā ʻeke plastik, shrink wraps, a me nā kiʻiʻoniʻoni mahiʻai.ʻIke ʻia ʻo LDPE no kona kūpaʻa maikaʻi ʻana i ka makū a me nā kemika, kūpono ia no nā noi e koi ana i kahi kiʻekiʻe o ka maʻalahi a me ka lōʻihi.Hoʻopuka pinepine nā mea hana kiʻiʻoniʻoni LDPE i kahi ākea o nā huahana e hoʻokō i nā pono like ʻole o kā lākou mea kūʻai.
Ma ka ʻaoʻao ʻē aʻe, ʻo ka HDPE kahi mea ʻoi aku ka ikaika a me ka ikaika i hoʻohālikelike ʻia me LDPE.Hoʻohana maʻamau ʻia ʻo HDPE i nā noi e koi ana i nā kiʻi ʻoniʻoni paʻa paʻa a paʻa, e like me ka hana ʻana i nā ʻeke kaumaha, tarpaulins, a me nā laina ʻoihana.ʻO ke kiʻiʻoniʻoni plastik HDPEʻike ʻia no kona ikaika tensile maikaʻi loa a me ke kūʻē ʻana i nā kemika, e lilo ia i koho kūpono no nā noi waho a me nā hana kaumaha.Nā mea hana kiʻiʻoniʻoni HDPEhana i ka nui o nā huahana e hoʻokō i nā noi ʻoihana a me nā ʻoihana.
I kēia manawa, e hoʻohālikelike kākou i nā mea ʻelua e pili ana i ko lākou mau waiwai a me nā ʻano.ʻIke ʻia ʻo LDPE no kona maʻalahi a me ka elasticity, i kūpono ia no nā noi e koi ana i ka stretchability a me ka conformability i nā huahana i hoʻopaʻa ʻia.Ma ka lima ʻē aʻe, ʻike ʻia ʻo HDPE no kona rigidity a me ka paʻakikī, kahi e kūpono ai i nā noi e koi ai i ka ikaika a me ka lōʻihi.I ka hiki ʻana mai i ke kūʻē kemika, hōʻike ʻo LDPE a me HDPE i ke kūpaʻa maikaʻi ʻana i ka makū a me nā kemika, e kūpono ana iā lākou no ka hoʻopili ʻana a me nā noi hoʻopaʻa.
Ma ke ʻano o ka hopena o ke kaiapuni, ʻo LDPE a me HDPE nā mea hiki ke hana hou ʻia.Eia nō naʻe, ʻae ʻia ʻo HDPE no ka hana hou ʻana i nā kaiāulu hou aʻe i hoʻohālikelike ʻia me LDPE.ʻO kēia no ka mea he kiʻekiʻe ka waiwai o HDPE i ka mākeke recycling ma muli o kāna mau waiwai ikaika a paʻa.ʻO ka hopena, makemake pinepine ʻia ʻo HDPE e nā mea kākoʻo kaiapuni a me nā mea kūʻai aku i ka hoʻomau.
I ka hopena, pili ka koho ma waena o HDPE a me LDPE i nā koi kikoʻī a me nā noi o ka mea hoʻohana.He kūpono ʻo LDPE no nā noi e koi ana i ka maʻalahi a me ka stretchability, ʻoiai ʻo HDPE kūpono no nā noi e koi ana i ka rigidity a me ka ikaika.Loaʻa i nā mea ʻelua kā lākou mau pono ponoʻī a me nā hemahema, a he mea nui i nā ʻoihana a me nā mea kūʻai aku e kūkākūkā me LDPE aNā mea hana kiʻiʻoniʻoni plastik HDPEe hoʻoholo i ka mea maikaʻi loa no kā lākou mau pono kikoʻī.ʻO ka hope loa, he kuleana koʻikoʻi nā mea ʻelua i ka hoʻokō ʻana i nā pono like ʻole o ka ʻeke, ka mahiʻai, a me nā ʻoihana kūkulu.
