He 70% o ka ʻili honua he moana. Mai nā uapo moana a hiki i nā alahaka kahakai nani a me ka mahiʻai kai hou, ua hana nā kānaka i nā waiwai he nui ʻole me ka hoʻohana ʻana i kēia moana nui. Eia nō naʻe, he mea nui nā mea hana maikaʻi no ka holomua. ʻO nā mea maʻamau e like me ka lāʻau, ke kila, a me ka sima he nui nā kumukūʻai mālama kiʻekiʻe loa a me nā ola palena. He mea nui ka loaʻa ʻana o kahi mea hou e hiki ke kū i ka pala o ka wai kai, ka ʻike ʻana i ka UV, ka ʻino ʻana o ka nalu, a me ka biofouling i nā wā lōʻihi. Ua puka mai ka polyethylene kiʻekiʻe (HDPE), kahi plastic ʻenekinia, me kāna hana kokoke i ka hemolele, e lilo ana i mea kūpono no ke kūkulu ʻana i nā hale kai.
No ke aha i lilo ai ʻo HDPE i mea kūpono loa?
1. Ke Kūʻē ʻana i ka ʻAi ʻOle: Hōʻike ka HDPE i ke kūpaʻa kiʻekiʻe e kūʻē i nā waikawa, alkalis, a me nā paʻakai, kūʻē i ka ʻai ʻana o ka wai kai, a ʻaʻole e popo e like me ke kila maʻamau a pala paha e like me ka lāʻau.
2. Paʻa a kū i ka hopena: ʻOiai ma -40 degere Celsius,Nā pepa HDPEmālama i ko lākou paʻa, e hōʻoluʻolu pono ana i nā hopena mai nā moku a me ke kūpaʻa ʻana i ka ʻinoʻino lōʻihi mai ka one.
3. Ka Mana Kū'ē i ka Hoʻopili ʻana: ʻO ka ʻili laumania loa o nā pepa HDPE e paʻakikī ai ka hapa nui o nā meaola wai e hoʻopili pono.
4. Māmā a maʻalahi loa: ʻOi aku ka liʻiliʻi o ka nui o nā pepa HDPE ma mua o ka wai, e maʻalahi ai ke kau a me ka lawe ʻana. Hiki ke hoʻohui pono ʻia lākou ma o ka hoʻoheheʻe wela e hana i kahi ʻano paʻa a hoʻohui ʻia.
5. ʻŌmaʻomaʻo a me ke aloha kaiapuni, 100% hiki ke hana hou ʻia:Mea HDPEhe 100% hiki ke hana hou ʻia, e lilo ia i mea ʻōmaʻomaʻo maoli a pili i ke kaiapuni.
6. Ola Hana Lōʻihi a me nā Kumukūʻai Mālama Haʻahaʻa: ʻAʻole koi nā pepa HDPE i ka mālama anti-corrosion a i ʻole ka pale pepeke i ko lākou ola holoʻokoʻa, e hopena ana i nā kumukūʻai mālama haʻahaʻa loa.
Ma hope o kekahi mau makahiki, ua loaʻa i kahi uapo e hoʻohana ana i nā pale lāʻau paʻa ma muli o nā pōʻaiapuni pulu-maloʻo a me ka hoʻoluʻu lōʻihi ʻana i loko o ka wai kai, e pono ai ke hoʻololi pinepine. A laila ua hoʻohana ʻia nā pale HDPE. ʻO kona paʻakikī e hiki ai iā ia ke omo pono a hoʻopuehu i ka ikehu kuʻi mai ka pae ʻana o ka moku, a ʻo kona kūpaʻa i ka pala a me ke kūpaʻa UV e hōʻoiaʻiʻo ana e mālama nā pepa HDPE i ko lākou kala no ka manawa lōʻihi, ʻaʻole pono ka mālama lōʻihi a me ka hoʻemi ʻana i nā kumukūʻai hana o ka uapo.
Ma nā mahiʻai iʻa salmon UK, nui loaPepa HDPEHoʻokumu nā mōlina i nā wahi mahiʻai ākea a me ka maikaʻi o ka wai. ʻAʻole e popopo nā mōlina pepa, a ʻo ko lākou mau ʻili laumania e hoʻopau i ka pono no ka hoʻomaʻemaʻe ʻana i nā waihona.
Mai nā pale o ke awa a hiki i nā hale mahiʻai kai, ua hōʻoia ka mea HDPE i kāna hana maikaʻi loa ma ke ʻano he mea kūpono no ke kaiapuni kai ʻino. Me ka ulu wikiwiki ʻana o ka hoʻokele waiwai kai, ʻo nā pepa HDPE, me ko lākou mau ʻano palekana, ʻoi aku ka paʻa, ʻoi aku ka launa pū me ke kaiapuni, a ʻoi aku ka hoʻokele waiwai, e pāʻani i kahi kuleana nui i ka hoʻokele waiwai polū e ulu ana, me nā kahua photovoltaic ma waho o ka wā e hiki mai ana a me nā awa e pili ana i ke kaiapuni.
