Ka laula o ka hale hānai: 1m-2m, hiki ke hoʻopili ʻiaʻa hoʻonui ʻia i 10m, 20m a ʻoi aku paha.
Mea hoʻolale moʻomeheu: uea nylon, polyethylene, uea thermoplastic.
ʻO ka ulana hale: ka ulana maʻamau, me nā mea maikaʻi o ke kaumaha māmā, ke ʻano nani, ka waikawa a me ke kūpaʻa alkali, ka pale ʻana i ka corrosion, ventilation, hoʻomaʻemaʻe maʻalahi, ke kaumaha māmā a me ke kumu kūʻai haʻahaʻa.ʻ
Nā hiʻohiʻona o nā hīnaʻi aquaculture: ʻO ka huahana he kūʻē i ka corrosion, pale ʻaila, pale wai, etc.
ʻO ke kala o ka hīnaʻi hānai;maʻamau uliuli/'ōmaʻomaʻo, hiki ke hoʻopilikino ʻia nā kala ʻē aʻe.ʻ
Hoʻohana ʻia i ka Cage: hoʻohana ʻia i loko o nā mahiʻai, mahiʻai rana, mahiʻai bullfrog, mahiʻai loach, mahiʻai eel, mahiʻai kai, mahi ula, mahi pāpaʻi, etc. Hiki ke hoʻohana ʻia i ʻupena meaʻai a me nā ʻupena pepeke.
ʻAʻole ʻono ka polyethylene, ʻaʻohe mea ʻawaʻawa, manaʻo e like me ka wax, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi loa (hiki ke piʻi ka mahana hana haʻahaʻa -100 ~ -70°C), paʻa kemika maikaʻi, a hiki ke pale aku i ka nui o ka waika a me ka erosion alkali (ʻaʻole kū i ka ʻakika kūlohelohe oxidation).ʻAʻole hiki ke hoʻoheheʻe ʻia i nā solvents maʻamau i ka lumi wela, me ka haʻahaʻa haʻahaʻa o ka wai a me ka insulation uila maikaʻi loa.
