Ua hoʻihoʻi ʻia kahi hale hana mea hale ma Polani i kahi kalaka holoʻokoʻa o ka plywood no ka mea ua kapa ʻia ka palapala hoʻopuka i nā paneli "softwood plywood." ʻO nā panela he birch. He mea maʻalahi ka manaʻo o ka mea kūʻai: inā he māmā ke kala a maʻalahi ka mīkini, pono e hele mai ia mai kahi lāʻau palupalu. ʻO kēlā manaʻo e uku i ka mea hoʻolako i hoʻokahi pule o ka hana ʻana, kahi hoʻopaʻi ukana, a me kahi kelepona paʻakikī. ʻO ka ʻoiaʻiʻo, ʻo ka lāʻau birch he lāʻau lāʻau paʻakikī, a ʻo ka huikau ka mea i loaʻa mai kahi ʻōnaehana inoa ʻaʻohe mea pili i ka paʻakikī o ka lāʻau ma lalo o kahi kui.
Inā ʻoe e kuhikuhi nei i nā panela no nā keʻena keʻena, ka mea hana paʻa, nā hiʻohiʻona i ʻoki ʻia i ka laser, a i ʻole nā pahu hoʻouna, pono kēia ʻokoʻa.

Aia ma lalo iho kahi wehewehe akaka a kūpono mai kahi mea hana e kaomi i ka lāʻau lāʻau birch i kēlā me kēia lā.
Hoʻokaʻawale ʻia ka lāʻau lāʻau birch ma ke ʻano he lāʻau paʻa. ʻO ke kumu he botanical, ʻaʻole kālepa. No ka genus Betula ka lāʻau birch a he lāʻau lau lau ākea. I ka ʻepekema lāʻau, ua kapa ʻia nā lāʻau lau a pau he lāʻau paʻa, a i ʻole he angiosperms. ʻO nā conifers e like me ka pine, spruce, fir, a me ke kedera i kapa ʻia he lāʻau palupalu, a i ʻole gymnosperms. Ma muli o ka ho'oka'awale 'ana o ka plywood mai ka 'ano i ho'ohana 'ia, 'o kēlā me kēia plywood i hana 'ia mai ka birch veneers he lā'au lā'au pa'a.
Pili kēia i kēlā me kēia papa a me ke ʻano hana. Plywood kumu birch piha? Laau paʻa. ʻO ka maka birch a me ke kua me kahi kumu poplar? He lāʻau lāʻau paʻa nō naʻe no ka mea he lāʻau paʻa nā maka. Plywood birch me ke kiʻiʻoniʻoni? ʻO ke kiʻiʻoniʻoni he uhi, ʻaʻole ia he ʻano lāʻau, no laila e mau ka panel i kahi lāʻau paʻa. ʻO ka lāʻau lāʻau birch ʻoi aku ka lahilahi a hiki ke hoʻohana ʻia no ka hana ʻana i nā kumu hoʻohālike e hāʻule i loko o ka ʻāpana lāʻau paʻakikī.
ʻO ka huaʻōlelo "lāʻau paʻa" ʻaʻole ia e pale aku i ka paʻi ʻana o ka hāmare e like me ke kila. ʻO ke ʻano o ka lāʻau mai kahi kumu lāʻau e hua ai i nā ʻanoʻano i loko o ka hua a i ʻole ka pūpū, hāʻule nā lau i ka wā hāʻule, a he mau moku i loko o kona ʻano kelepona. Nānā ʻo Birch i kēlā me kēia pahu.
Lohe ka nui o ka poʻe i ka "lāʻau paʻa" a me ke kiʻi ʻoka, maple, a i ʻole wōnati. Lohe lākou i ka "lāʻau palupalu" a me ke kiʻi pine, spruce, a balsa paha. Ke hana nei ka ʻaoʻao pōkole noʻonoʻo i ka hapa nui o ka manawa, akā hāʻule pinepine ia i mea e hewa ai ke kūʻai ʻana. He lāʻau paʻakikī ka Balsa, akā ʻoi aku ka palupalu ma mua o nā lāʻau palupalu. He lāʻau palupalu ka longleaf pine, akā ʻoi aku ka paʻakikī ma mua o nā lāʻau paʻakikī. ʻO ka ho'āʻo paʻakikī Janka e ana i ke kū'ēʻana i ka niho, aʻokiʻoki i ka māhele botanical.
ʻO Birch ka lāʻau paʻa maoli a me ka lāʻau paʻakikī maoli. Ma ka pālākiō Janka, helu ʻia ka birch melemele ma kahi o 1,260 lbf, ʻoiai ʻo ka paina keʻokeʻo hikina he 420 lbf. ʻO ia hoʻi, ʻoi aku ka paʻa ʻana o ka maka birch plywood i nā niho ma mua o ka maka pine o ka mānoanoa like. ʻO ka hoʻokaʻawale ʻana a me ka hana ʻae ʻana i kēia hihia, akā ʻae like lākou ma ka coincidence, ʻaʻole ma ka wehewehe.
Ke hoʻopaʻa inoa ka mea hoʻolako i kahi papa "lāʻau lāʻau palupalu," ʻo ia ka mea maʻamau i hele mai nā veneers mai kahi conifer. Ke nīnau ka mea kūʻai aku inā he lāʻau palupalu a lāʻau paʻakikī paha ka birch plywood, ʻōlelo pinepine lākou "e maʻalahi anei kēia papa?" He ʻokoʻa ka pane i nā nīnau ʻelua. ʻO Birch plywood ka lāʻau paʻakikī ma nā ʻano a me ka paʻakikī ma ka hana.
Inā makemake ʻoe e hōʻoia i ka hoʻokaʻawale ʻana iā ʻoe iho, e nānā i ka lāʻau, ʻaʻole ka panel. He lau ākea a pālahalaha ka lāʻau Birch me nā ʻaoʻao serrated. Hāʻawi lākou i nā pōpoki, he mau pūʻulu elongated o nā pua. He ʻanoʻano liʻiliʻi, ʻēheu ʻēheu. ʻO kēia nā hiʻohiʻona maʻamau o nā angiosperms, nā mea kanu pua. ʻO nā lāʻau palupalu e like me ka pine a me ka spruce he lau like me ka nila, hua mai nā cones, a hāʻawi i nā ʻanoʻano ʻōlohelohe. Loaʻa i kā lākou lāʻau nā tracheids no ka lawe ʻana i ka wai, ʻoiai ʻo ka lāʻau paʻa nā moku.
Ma lalo o ka leki lima, e hōʻike ana kahi veneer birch i nā pores maikaʻi a i ʻole nā moku i hoʻopuehu ʻia ma ka ʻili. Hōʻike ka lāʻau paina i kahi ʻano like ʻole, ʻano resinous me nā kaula lāʻau mua a me nā kaula latewood. ʻO kēia ʻokoʻa microscopic ke kumu e lawe ai ka birch i ka ʻeleʻele a hoʻopau ʻokoʻa mai ka pine. ʻO ia hoʻi ke kumu e hiki ai ke hoʻolele ʻia i ka lāʻau birch i kahi ʻili maʻemaʻe loa me ka ʻole o ka fuzziness e ʻike ʻia i kekahi manawa ma nā veneer lāʻau palupalu.
ʻO ka Plywood kahi papa hana ʻenekinia i hana ʻia mai nā ʻāpana lahilahi o ka veneer lāʻau, i kapa ʻia ʻo plies, i hoʻopili ʻia me nā ʻaoʻao o ka palaoa. ʻO ke ʻano o ia mau plies e hoʻoholo inā he lāʻau paʻa a i ʻole ka lāʻau palupalu ka papa hope. ʻAʻole hoʻokaʻawale nā mea hana i ka plywood e ka mea hoʻopili, ka uhi kiʻiʻoniʻoni, ka mānoanoa, a i ʻole ka helu o nā plies. Hoʻokaʻawale lākou ma muli o ka lāʻau.
Hoʻomaka ka manaʻo kuhihewa me ka "combi" a i ʻole "mixed" plywood, kahi o ke kumu he lāʻau palupalu e like me ka poplar a ʻo nā maka he birch. Ma ke kālepa, kūʻai pinepine ʻia kēia ma ke ʻano he birch plywood no ka mea he birch nā maka i ʻike ʻia. ʻO ka ʻōlelo koʻikoʻi, he lāʻau paʻa i ke alo me kahi kumu lāʻau palupalu. No nā helu hoʻonohonoho, pono ke kumu. No ka helehelena a me ka paʻakikī o ka ʻili, pono ke alo. E noi mau i ka hana piha inā e lawe ka panel i ka ukana a i ʻole e ʻike ʻia i ka wai.
Hoʻohana ka lāʻau lāʻau birch piha i nā veneers birch a puni. ʻO kēia ka koho ikaika a kūpaʻa loa. ʻO ia hoʻi ka papa i manaʻo ʻia e ka hapa nui o nā mea kūʻai aku ke nīnau lākou e pili ana i ka lāʻau birch. ʻO kahi kikoʻī alakaʻi lāʻau lāʻau birch hiki ke kōkua iā ʻoe e hoʻohālikelike i nā māka maka, nā ʻano kumu, a me nā papa hoʻopili ma mua o kou kau ʻana i kahi kauoha.
Hoʻokahi papa o ka huikau: hoʻohana kekahi mau mea hoʻolako i ka "lāʻau lāʻau paʻa" ma ke ʻano he huaʻōlelo kūʻai no kēlā me kēia plywood hoʻonani, ʻoiai inā he lāʻau palupalu ke kumu.

Inā he birch ka ʻāpana keʻa holoʻokoʻa, he lāʻau lāʻau paʻa ia ma ke ʻano hoʻolālā.
