III. Nā mea hana a me ka hana ʻana o ka uhi uhi
ʻO ka uhi uhi kīʻaha he papa pale e pale ai i loko o nā kīʻaha pepa hau. ʻO nā ʻano mea i hoʻohana mau ʻia e like me kēia.
A. ʻO ke ʻano o nā mea i hoʻohana ʻia no ka uhi ʻana o nā kīʻaha pepa, e like me ka polyester, polyethylene, etc.
1. Polyethylene
Hoʻohana nui ʻia ka Polyethylene i ka uhi ʻana o nā kīʻaha pepa no ka maikaʻi o ka wai a me ka ʻaila kūpaʻa waiwai, a me kona kumu kūʻai haʻahaʻa. Hana ia i mea kūpono no ka hana ʻana i nā kīʻaha pepa ice cream nui.
2. Polyester
Hiki i nā pale polyester ke hāʻawi i nā pae kiʻekiʻe o ka pale. No laila, hiki iā ia ke pale i ka ʻala, ke komo ʻana o ka momona, a me ke komo ʻana o ka oxygen. No laila, hoʻohana maʻamau ka polyester i nā kīʻaha pepa kiʻekiʻe kiʻekiʻe.
3. PLA (ʻakika polylactic)
ʻAʻole maikaʻi ka hana wai ʻole o ka PLA, akā pili ia me ka pale o ke kaiapuni a hoʻohana nui ʻia i kekahi mau mākeke kiʻekiʻe.
B. Hoʻokomo i ka hana hana, e like me nā ʻenehana hoʻopili kūikawā a me ka welding
ʻO ke kaʻina hana o ka uhi uhi no nā kīʻaha pepa penei:
1. ʻenehana pale kūikawā
I ke kaʻina hana o nā kīʻaha pepa, hoʻohana nui ʻia ka uhi uhi e hōʻoia i ka hopena wai a me ka ʻaila o nā kīʻaha. ʻO ke ʻano o ka hōʻoia ʻana i ka māhele like ʻana o ka uhi i loko o ke kīʻaha holoʻokoʻa e hoʻohana i ka ʻenehana injection hou. ʻO ka mua, hopu ʻia ka sediment i hana ʻia a hoʻomākaukau ʻia, a laila hoʻokomo ʻia i loko o ke kīʻaha pepa.
2. wiliwili
I kekahi mau hihia, ʻaʻole pono nā uhi ʻenehana kūikawā. I kēia hihia, hiki i ka uhi o loko o ke kīʻaha pepa ke hoʻohana i ka ʻenehana wela sealing (a i ʻole welding). He kaʻina hana kēia o ke kaomi ʻana i nā ʻāpana he nui o nā mea like ʻole, e hoʻopaʻa paʻa i ka uhi o loko a me ke kino kīʻaha. Ma ka hāʻawiʻana i kahi pale pale hilinaʻi, e hōʻoia kēia kaʻina hana i ka lōʻihi o ke kīʻaha pepa a hikiʻole ke kahe.
ʻO ka mea i luna nei he hoʻolauna i nā ʻano mea a me nā kaʻina hana no ka uhi ʻana o nā kīʻaha pepa. Nā mea e like meʻO ka polyethylene a me ka polyester ka mea kūpono no nā māka like ʻole o ke kīʻaha pepas. Aʻo kaʻenehana hoʻopili kūikawā a me nā kaʻina hana hana welding hiki ke hōʻoia i ka maikaʻi a me ka hana o ka uhi kīʻaha pepa.
