Ua hana pū mākou i nā lako i hana ʻia me nā mea ʻē aʻe ma waho o nā lāʻau, me ka lāʻau a me nā papa manamana lima, akā i kēia manawa ke hana wale nei mākou i ka lāʻau me ka hoʻohana ʻana i kēia mau mea: E0, E1, a me E2 e pili ana i nā kūlana kaiapuni me nā pae palena o ka hoʻokuʻu formaldehyde.E2（≤ 5.0mg/L）、E1（≤1.5mg/L）、E0（≤0.5mg/L）
ʻO E1 kahi koi kumu no ka plywood kalepa e kū ai i nā kūlana ola.Me ka piʻi ʻana o ka makemake no nā huahana,
Ke hoʻonui nui nei ka lāʻau paʻa paʻa i ka pae i ka E0.
Pehea e hoʻokaʻawale ai i ka maikaʻi o ka plywood, hiki ke hoʻokaʻawale ʻia mai nā mea aʻe:
ʻO ka mea mua, maikaʻi ka ikaika paʻa;ʻOi aku ka maikaʻi o kēlā me kēia ʻano o ka ikaika adhesive, ʻo ia hoʻi, ʻo ka ikaika adhesive ka mea e pono ai.ʻO ka mea mua, e nānā inā ʻike ʻia nā ʻano ʻano hoʻopaʻa ʻana a puni a inā he mau ʻōhū ma ka ʻili.ʻO ka lua, ma ke kaomi lima ʻana a me ke kaomi ʻana i ka puʻu, lohe ʻoe i kekahi walaʻau.ʻOiaʻiʻo, inā he walaʻau, ʻaʻole paha ma muli o ka maikaʻi ʻole o ka hoʻopili.Ma muli paha o ke kumu ʻole a i ʻole nā mea ʻilihune i hoʻohana ʻia no ka papa kumu, akā e hōʻike ana nā mea a pau ʻaʻole maikaʻi ka maikaʻi.
ʻO ka lua, maikaʻi ka palahalaha;Mai kēia wahi, hiki ke ʻike ʻia ua hoʻohana ʻia nā mea i loko o ka papa.Ke nānā nei mākou i kahi papa, hoʻopā mākou me ko mākou mau lima e ʻike inā loaʻa kahi ʻole.Inā loaʻa kekahi, hōʻike ia i ʻelua mau kiko: ʻaʻole maikaʻi ke one o ka ʻili, a i ʻole ka papa kumu i hana ʻia me nā mea ʻilihune, i ʻoki ʻia.
ʻO ke kolu, ʻo ka mānoanoa o ka papa, ʻoi aku ka maʻalahi o ka ʻike.No ka laʻana, hana ʻia kahi plywood multi-layer 18cm ma ke kaomi ʻana i 11 papa o ka papa kumu.Inā hana ʻia kēlā me kēia papa me nā mea holoʻokoʻa, akaka loa nā papa a ʻaʻohe mea e ʻike ʻia ai nā papa hili.Inā ʻaʻole hoʻohana maikaʻi ʻia nā mea a he nui nā mea i ʻoki ʻia, ma muli o ke kaomi ʻana, e uhi ʻia nā papa a hana ʻole i ka ʻili.
ʻO ka hā, ʻaʻole deform ka papa maikaʻi;ʻO ke kiʻekiʻe o ka deformation e pili nui ana i nā waiwai kino o ka lāʻau ponoʻī, kona ʻano maʻamau, a me ke aniau.ʻO ka mea hiki iā mākou ke hoʻomalu ʻo ia ka moisture content.Hiki iā mākou ke koho i ka lāʻau me ka liʻiliʻi o ka deformation.
ʻO ka lima, inā paha i loko o ka laulā maʻamau ka mānoanoa;ʻO ka ʻōlelo maʻamau, ʻo ka mānoanoa o nā papa maikaʻi i loko o ka laulā o nā kūlana aupuni.
Ua like ka mua o ka papa manamana me ko ka plywood multi-layer.ʻO ka papa manamana lima ka papa i hana ʻia ma ka hoʻopili ʻana i ka ʻōpala i koe ma hope o ka hoʻoponopono ʻana i ka lāʻau maka, a ʻo ka papa multi-layer kahi papa e ʻoki ai i ka papa lāʻau kumu i ʻāpana lahilahi a laila hoʻopili pū.Ua like nā kumukūʻai o nā mea ʻelua, akā ma muli o ka nele o ka waiho ʻana i ka papa manamana lima, ʻoi aku ka maʻalahi o ka deformation i hoʻohālikelike ʻia me ka multi-layer plywood.
ʻAʻole i like ka nui o ka hoʻohana ʻana o nā papa ami manamana lima e like me ka nui o nā papa ʻāpana.No ka laʻana, inā hoʻohana ʻia kekahi mau mea elongated me nā papa ami manamana lima, ʻaʻole maikaʻi ko lākou haʻahaʻa haʻahaʻa e like me ka nui o ka plywood, a ua maʻalahi lākou i ka haki ʻana ma lalo o kekahi ʻano o ka ikaika o waho.Hoʻohana mau ʻia nā papa manamana lima e hana i nā pani puka nui a me nā papa.A hiki ke hana ʻia kēia mau lāʻau paʻipaʻi nui, no laila ʻaʻole mākou e hoʻohana i nā papa hui manamana lima i kēia manawa.
