Introduction to plywood.

ʻO ka Plywood kahi mea ʻekolu-papa a i ʻole multi-layer papa-like i hana ʻia me nā ʻāpana lāʻau i ʻili ʻia i loko o nā veneers a i ʻoki ʻia i loko o ka lāʻau lahilahi, a laila hoʻopili ʻia me nā mea hoʻopili. ʻO ka maʻamau, hoʻohana ʻia nā veneers helu ʻē aʻe, a hoʻohana ʻia nā ʻāpana pili o nā veneers. Hoʻopili ʻia nā ʻaoʻao fiber e pili pono ana kekahi i kekahi.

ʻO ka Plywood kekahi o nā mea hoʻohana maʻamau no nā lako, a ʻo ia kekahi o nā papa nui ʻekolu o nā paneli kumu lāʻau. Hiki ke hoʻohana ʻia no nā mokulele, nā moku, nā kaʻaahi, nā kaʻa, nā hale a me nā pahu pahu. Hoʻohui pinepine ʻia kahi hui o nā veneers a hoʻopili ʻia e like me ke kuhikuhi ʻana o ka hua lāʻau o nā papa pili e kū pono ana kekahi i kekahi. ʻO ka mea maʻamau, ua hoʻonohonoho like ʻia ka papa ʻili a me ka papa o loko ma nā ʻaoʻao ʻelua o ka papa waena a i ʻole ke kumu. ʻO ka papa i hana ʻia i ka veneer ma hope o ka hoʻopili ʻana e hoʻopili ʻia e like me ke kuhikuhi ʻana o ka hua lāʻau, a kaomi ʻia ma lalo o ka hoʻomehana ʻana a i ʻole ka wela ʻole. He helu ʻokoʻa ka helu o nā papa, a he mau helu like kekahi. He liʻiliʻi ka ʻokoʻa o ke kino a me ka mechanical i ka ʻaoʻao kū a me ka pae. ʻO nā ʻano lāʻau i hoʻohana mau ʻia, ʻo ia ka papa ʻekolu, ka papa ʻelima a pēlā aku. Hiki i ka Plywood ke hoʻomaikaʻi i ka hoʻohana ʻana i ka lāʻau a he ala nui ia e mālama ai i ka lāʻau.

I mea e hoʻomaikaʻi ai i nā waiwai anisotropic o ka lāʻau maoli e like me ka hiki, i ʻano like nā ʻano o ka plywood a paʻa ke ʻano, pono ke ʻano o ka plywood maʻamau i nā kumu kumu ʻelua: ʻo ka symmetry; ʻo ka ʻokoʻa ʻē aʻe, ʻo nā ʻili o nā ʻāpana pili o ka veneer e kū pono ana kekahi i kekahi. ʻO ke kumu o ka symmetry, ʻo ia ke koi ʻana i nā veneers ma nā ʻaoʻao ʻelua o ke kikowaena kikowaena symmetrical o ka plywood e like me kekahi i kekahi me ka nānā ʻole i ke ʻano o ka lāʻau, ka mānoanoa o ka veneer, ka helu o nā papa, ke kuhikuhi o ka nā pulupulu, a me ka mākū. I loko o ka plywood hoʻokahi, hiki ke hoʻohana ʻia nā veneers o kahi ʻano hoʻokahi a me ka mānoanoa, a i ʻole nā ​​veneers o nā ʻano like ʻole a me ka mānoanoa; akā naʻe, ʻo kēlā me kēia ʻāpana ʻelua o nā veneers i hoʻohālikelike ʻia kekahi i kekahi ma nā ʻaoʻao ʻelua o ka mokulele kikowaena symmetrical pono ke ʻano like a me ka mānoanoa. ʻAʻole ʻae ʻia nā ʻaoʻao o ke alo a me ke kua i nā ʻano lāʻau like.

No ka hoʻokō ʻana i ke ʻano o ka plywood i nā kumu kumu ʻelua ma luna aʻe i ka manawa like, pono ke ʻano o kona helu o nā papa. No laila, hana mau ʻia ka plywood i mau papa helu ʻē aʻe e like me ʻekolu papa, ʻelima papa, a ʻehiku papa. ʻO nā inoa o kēlā me kēia papa o ka lāʻau: ua kapa ʻia ka ʻili o ka ʻili ʻo ka papa ʻili, ʻo ka ʻili o loko i kapa ʻia ʻo ka papa kumu; kapa ʻia ka papa mua ʻo ka papa, a ʻo ka papa hope i kapa ʻia ʻo ka papa hope; i loko o ka papa kumu, ua like ka ʻaoʻao fiber me ka papa Ua kapa ʻia ka papa lōʻihi a i ʻole ka papa waena. I ka hana ʻana i nā papa o ka lua, pono ke alo i waho o ka mua a me ke kua.
