No ke aha e ʻoi aku ka lahilahi o ka mānoanoa pā o ke kīʻaha thermos

E hoʻomaka ana i ka makahiki 2017, ua hoʻomaka nā kīʻaha māmā i ka mākeke kīʻaha wai, a ma hope koke iho, ua hoʻomaka nā kīʻaha ultra-māmā i ka mākeke. He aha ke kīʻaha māmā? He aha ke ana kīʻaha ultra-māmā?

ʻO ka lawe ʻana i kahi kīʻaha thermos stainless steel 500 ml ma ke ʻano he laʻana, ʻo ke kaumaha o ka ʻupena i hana ʻia e like me nā hana kuʻuna ma waena o 220g a me 240g. Ke noho like ka hale a like ka uhi, aia ke kaumaha o ke kīʻaha māmā ma waena o 170g a me 150g. ʻO ke kaumaha o ke kīʻaha māmā ma waena o 100g-120g.

Pehea e hana ʻia ai nā kīʻaha ana māmā a māmā?

I kēia manawa, ʻano like nā kaʻina hana i lawe ʻia e nā hui like ʻole, ʻo ia hoʻi, ʻo ke kino kīʻaha i loaʻa ke kaumaha maʻamau e like me ke kaʻina hana kuʻuna e hana hou ʻia ma o ke kaʻina hana lahilahi. Ma muli o ke ʻano o ka huahana, hiki ke loaʻa nā mānoanoa lahilahi ʻokoʻa. Ma hope o ka wehe ʻana i ka mea i ʻoki ʻia i loko o ke ʻano i ʻae ʻia e ke kaʻina hana, e maʻalahi ke kino kīʻaha i kēia manawa.

ʻAe, ua hana mākou i kahi kaulana hou o nā kīʻaha māmā i ka wā ma mua. I kēia manawa, ke pane nei mākou i ka nīnau no ke aha ka lahilahi o ka mānoanoa o ka paia o ke kīʻaha thermos, ʻoi aku ka maikaʻi o ka hopena insulation. Nui nā ʻatikala mua i haʻi i ke kaʻina hana o ka insulation thermal o nā kīʻaha thermos. No laila, ma muli o ka loaʻa ʻana o ka insulation thermal ma o ke kaʻina ʻawaʻawa, pehea ka pili ʻana i ka mānoanoa o ka pā kīʻaha? Ke hoʻohana ʻia ke kaʻina hana like a like like nā ʻenehana ʻenehana o ka hoʻoheheʻe ʻana, ʻo ka mānoanoa o ka pā o ke kīʻaha thermos e hoʻolōʻihi i ka wela, a ʻoi aku ka nui o nā mea pā mānoanoa i ka wela, no laila e hoʻopau ka wela. e wikiwiki. He liʻiliʻi ka puʻupuʻu hoʻopaʻa wela o ke kīʻaha thermos pā lahilahi, no laila e lohi ka wela.

Akā, pili kēia nīnau. ʻAʻole hiki ke ʻōlelo ʻia ʻo ke kīʻaha thermos me ka paia lahilahi e hoʻokaʻawale loa. ʻOi aku ka maikaʻi o ka hopena insulation i ka maikaʻi o ka ʻenehana hana a me nā kūlana o ka hoʻokele kaʻina hana. I ka manawa like, ʻaʻole kūpono nā kīʻaha wai a pau no ke kaʻina hana milo. Aia kekahi mau huahana me ka mana nui e like me nā ʻōmole thermos 1.5-lita. ʻOiai inā hiki i kā lākou hoʻolālā ke hoʻokō i ka hana ʻana o ke kaʻina hana spin-thinning, ʻaʻole pono e hoʻohana i ka ʻenehana spin-thin. ʻAʻole paipai ʻia ka ʻenehana spin-thin. Pono nō hoʻi ka mānoanoa o ka pā i loko o kahi ākea kūpono.

Inā lahilahi ka mānoanoa o ka pā, ʻoi aku ka haʻahaʻa o ka ikaika tensile e hiki ke kū ma mua o ka ikaika suction i hana ʻia e ka hoʻoheheʻe ʻana, a ʻo ka hopena liʻiliʻi ka deformation o ka paia kīʻaha. I nā hihia koʻikoʻi, e paʻi ka pā i loko a me ka pā i waho, i ʻole e hoʻokō ʻia ka hopena mālama wela. ʻOi aku ka ikaika o ka hoʻomohu ʻana e ke kīʻaha thermos nui a i ʻole ke kīʻaha thermos ma hope o ka hoʻokuʻu ʻia ʻana ma mua o ke kīʻaha wai liʻiliʻi. ʻO ka pā o kahi kīʻaha wai liʻiliʻi e hiki ke hoʻokō i ka paʻa ma hope o ka hoʻoheheʻe ʻia ʻana e hoʻololi ʻia ma kahi ipu nui.
