He aha ka plywpod

PlywoodʻO ia kekahi o nā mea hana maʻamau no nā mea hana hale, a he ʻano papa lāʻau. Hoʻopili pinepine ʻia kahi hui veneers e like me ke kuhikuhi ʻana o ka lāʻau o nā papa pili e kū pono ana kekahi i kekahi. Hoʻonohonoho like ʻia nā papa ʻāpana he nui 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 ka mea maʻamau ka hoʻohana ʻana i nā papa multi-layer e like me ka papa ʻekolu a me ka papa ʻelima. Hiki i nā papa multilayer ke hoʻomaikaʻi i ka hoʻohana ʻana i ka lāʻau a he ala nui ia e mālama ai i ka lāʻau. Hiki ke hoʻohana ʻia i mea waiwai no nā mokulele, nā moku, nā kaʻaahi, nā kaʻa, ke kūkulu ʻana a me nā pahu pahu.
ʻO ka Plywood, ka mea i kapa ʻia ʻo ʻekolu-plywood a me ʻekolu-ply board, he mau inoa like ʻole no nā papa like ʻole. Wahi a ka mānoanoa o 3-9 cm, hiki ke kapa ʻia ʻo 3-9 cm papa. ʻO kāna mau mea maikaʻi a me nā hemahema e hilinaʻi nui ʻia i nā mea maka. ʻO ke kumukūʻai o kēlā me kēia papa 1.2 * 4m o Liu Anxin he 10-20 yuan. A ʻoi aku ka maikaʻi o ka mahogany a me ka poplar.
ʻO ka mea nui i hoʻohana ʻia i ka hoʻonaninani hale ʻo ia ka plywood veneer, ʻo ia hoʻi, ua hoʻopili ʻia ka veneer lāʻau paʻa lahilahi ma luna o ka lāʻau i loko o ka hale hana. He maʻalahi ka hoʻohana ʻana i ka veneer plywood, a ʻoi aku ka liʻiliʻi o ke kumukūʻai ma mua o ke kūʻai ʻana i ka veneer iā ʻoe iho a ʻae i ka hui kūkulu hale e hoʻopili iā ia.
ʻO nā kikoʻī o ka plywood ua like ia me nā mea o ka hale maʻamau, ma ke ʻano: 1220 × 2440mm, a ʻo nā kikoʻī mānoanoa e like me: 3, 5, 9, 12, 15, 18mm, etc. ʻO nā ʻano lāʻau nui: camphor, willow, poplar, eucalyptus a pēlā aku.
