Mea Hoʻopaʻa Kalipuna a me ka Zinc
Me ka hoʻonui ʻana o ka ʻike palekana kaiapuni ma nā ʻāina āpau o ka honua, ua hoʻomaikaʻi mālie ʻia nā kānāwai a me nā lula palekana kaiapuni, ʻoiai nā koi maʻemaʻe no nā huahana plastik e like me ka lāʻau lapaʻau, ka hana ʻana i ka meaʻai, nā mea pono o kēlā me kēia lā, a me nā plastik mea pāʻani. E pani piha ʻia nā mea hoʻopaʻa paʻakai kēpau a me ka cadmium e nā mea hoʻopaʻa PVC ʻona ʻole. . ʻO ka hana ʻana o nā mea hoʻohui plastik haole e lilo i mea nui a kūikawā, mahalo nui ʻia nā koi palekana kaiapuni, a kūpono a multi-functional. Ua lilo ka noiʻi a me ka hoʻomohala ʻana i nā mea hoʻopaʻa PVC aloha kaiapuni a ʻona ʻole i mea hiki ʻole ke pale ʻia. ʻO ke kuhikuhi ʻona ʻole o nā mea hoʻopaʻa wela PVC e kālele nui ʻia ma nā ʻano ʻelua o ka organotin a me nā mea hoʻopaʻa wela calcium-zinc, a ua holomua nui nā mea ʻelua. Hōʻike nui ʻia ia ma ka noiʻi holomua a me ka hoʻohana nui ʻana i nā mea hoʻopaʻa wela organotin i hōʻike ʻia e ʻAmelika Hui Pū ʻIa, a me ka hoʻolaha ʻana a me ka hoʻohana ʻana i nā mea hoʻopaʻa wela calcium-zinc ʻona ʻole i hōʻike ʻia e ʻEulopa, akā ʻoi aku ke kumukūʻai o ka organotin. E kūkulu hope ka mea hoʻopaʻa hui calcium-zinc i ka ʻōnaehana hoʻopaʻa PVC ʻona ʻole o nā ʻāina āpau o ka honua.
Hoʻohana ʻia i loko o nā paipu, nā ʻikepili, nā mea hoʻopili paipu, nā papa, ka hoʻoheheʻe ʻana i ka injection, ka ʻoniʻoni hoʻoheheʻe puhi, nā mea uwea a me nā huahana plastik ʻē aʻe;

1. Mea hoʻopaʻa palekana kaiapuni ʻōmaʻomaʻo maoli;
2. Kūlana kūpaʻa wela maikaʻi loa;
3. Hāʻawi i ka mea hoʻopihapiha i ka hoʻolaha maikaʻi a hoʻomaikaʻi i nā waiwai mechanical o ka huahana;
4. E hōʻemi i ka ʻaʻahu mechanical a hoʻolōʻihi i ke ola lawelawe o nā lako;
5. Hiki ke hoʻohana ʻia no nā huahana moakaka a hāʻawi i nā huahana i ka permeability maikaʻi.
