He aha ka plywood

ʻO Plywood kahi ʻano papa lāʻau i hana ʻia e ke kanaka e ʻākoakoa hou ʻia e ka ʻili.

Hana ʻia ʻo Plywood e ka ʻoki ʻana i nā veneers nui ākea i ke kuhikuhi o nā apo makahiki. Ma hope o ka hoʻomaloʻo ʻana a me ka hoʻopaʻa ʻana, hana ʻia ia e like me ke kūlana o ke kū ʻana o ka hua mahogany kū i luna o nā mea wili pili.
ʻO ka helu o nā papa nui he helu maʻamau o nā papa, maʻamau ʻekolu a ʻumikūmākolu mau papa, a ʻo ka helu maʻamau o nā papa he ʻekolu mau papa, ʻelima mau papa, ʻeiwa mau papa, a me 13 mau papa (ʻo ka mākeke kūʻai aku i kapa ʻia he ʻekolu plywood, ʻelima plywood, ʻeiwa plywood, ʻumikūmākolu kenimika). ʻO ka veneer o mua o ka papa waho ka mea i kapa ʻia ka panela mua, kapa ʻia ka hope i ka peʻa hope, a ʻo ka papa i loko i kapa ʻia ka papa nui.

ʻAno ka plywood 1 i nā kūlana maikaʻi o ke aniau kūpale, kūpale ʻana i ka wai, kūpaʻa, kūpaʻa wela kiʻekiʻe, a me nā kūpaʻa mahu.

ʻO kēia mau ʻano pipe he plywood wai ʻole, hiki ke pulu i ka wai anuanu a me ka wai wela i kahi manawa pōkole.

ʻO ka 3 plywood he plywood wai ʻole, i hiki ke komo ʻia i loko o ka wai anuanu no kahi manawa pōkole, kahi kūpono no ka mahana o ka lumi i loko o ka lumi. Nā pono hana a me nā pono hana kūkulu maʻamau;
ʻAno 4 plywood ka waiū-hoʻopale plywood, i hoʻohana mau ʻia i loko o ka hale. Hoʻohana pinepine ʻia ka plywood me ka birch, eucalyptus, a me ka poplar.

Hoʻohana nui ʻia ka Plywood i nā kūlana waho, e like me ke kūkulu ʻana i nā mea hoʻonani o waho a me ka formwork paʻa. I nā mea hoʻonaninani, hoʻohana nui ʻia ia i nā kaupaku, nā pale o ka paia, a me nā pale o ka papahele.

Ke kumu o ka haku mele ʻana o ka plywood

I mea e hoʻomaikaʻi ai i ka anisotropy o ka lāʻau kūlohelohe e like me ka hiki, hiki i ka plywood ke ʻano like a me ke ʻano paʻa. ʻO ka mea maʻamau, pono ka pīpī e hāhai i ʻelua mau kumu maʻamau i ka hanana: hoʻokahi symmetrical; ʻo ka mea ʻē aʻe e pili pono ana nā ʻōnaehana optika pā hoʻokahi. 

ʻO ke kumumanaʻo o ka symmetry e koi ʻia ka plywood ma nā ʻaoʻao ʻelua o ka mokulele waena o ka plywood, me ka nānā ʻole i ke ʻano o ka wahie, ka mānoanoa o ka plywood, ka helu o nā papa, ka ʻaoʻao o ka fiber, a me ka waiū. pono ka symmetrical o kekahi i kekahi. 

I loko o ka plywood hoʻokahi, hiki ke hoʻohana i nā kumulāʻau a me nā veneers o ka mānoanoa, a i ʻole nā ​​veneers o nā ʻano lāʻau like ʻole a me nā mānoanoa e hoʻohana ʻia; Eia nō naʻe, ʻelua mau papa o nā kumu lāʻau veneer like symmetrical a me nā mānoanoa ma nā ʻaoʻao ʻelua o ka mokulele waena symmetry. 

I mea e hoʻokō ai i ke ʻano o ka plywood i nā kumu kumu ʻelua i luna, pono ʻē ka helu o nā papa. 

No laila, mahele pinepine ʻia ka plywood i ʻekolu mau papa, ʻelima mau papa, ʻehiku mau papa a me nā ʻano ʻē ʻē aʻe.

ʻO ka inoa o ka papa plywood: kapa ʻia ka veneer o ka papa i ka papaʻaina, ua kapa ʻia ka veneer o loko ka papa nui; ua kapa ʻia ka ʻaoʻao mua i ka papa, a ʻo ka ʻaoʻao hope i kapa ʻia ʻo ka ʻaoʻao hope. i ka papa kumu, kūlike ke kuhikuhi fiber i ka panela. 

Kapa ʻia ia papa lōʻihi lōʻihi a i ʻole papa waena.

Nā pōmaikaʻi o ka plywood
ʻO nā mea maikaʻi o ka wīlī i ka hiki i ka ikaika, ʻaʻole maʻalahi e deform a kūlou, ʻaʻole maʻalahi e haki, a me ka hoʻonui liʻiliʻi. He hiki i ka papa multilayer ke hoʻololi i ka mahana o ka hale a me ka momona. ʻO ka papa o ka papa multilayer he lāʻau kūlohelohe. ʻO ka palaoa wahie kokoke loa i ke ʻano a nui ka hōʻano. ʻO nā mea maikaʻi o nā papa multi-layer maʻalahi e wehe. Hoʻohālikelike ʻia me ka wahie paʻa lāʻau, pale ka papa nunui-papa i kekahi mau kīnā kūlohelohe o ka lāʻau kūlohelohe, e like me ka stutter, ka laulā, deformation, a me ke kūmau kūpikipiki maikaʻi ʻole.

ʻOi aku ka maikaʻi o nā papa multi-layer ma mua o ka lāʻau kūlohelohe i ke kumukūʻai. Ma muli o ke kālailai hou ʻana a me ka hoʻonohonoho hou ʻana o nā papa multi-layer, ʻoi aku ka maikaʻi o ka ʻoi aku o ka maikaʻi ma mua o nā papa lāʻau lāʻau paʻa.

Nā mea maikaʻi ʻole o ka papa multilayer
Hana ʻia ka papa multi-layer i ka papa kumu lāʻau kūlohelohe ma o ka mahana kiʻekiʻe a me ke kaomi kiʻekiʻe e kaomi ana i kahi kaomi wela me kahi mea hoʻopili. No laila, e pili ana i ka pale o ke kaiapuni, e hoʻokuʻu ʻia kekahi formaldehyde. Akā kokoke ia i ka lāʻau kūlohelohe a ʻo ia hoʻi ka papa hana ʻino ʻoluʻolu loa.

Ka ʻike ʻana i ka plywood maikaʻi a maikaʻi ʻole paha
ʻO ka mea mua, e nānā i ka pālahalaha o ka panela. Mai kēia kiko, hiki iā mākou ke ʻike i nā mea o loko o ka papa. Ke nānā mākou i kahi papa, hiki iā mākou ke hoʻopā iā ia me ko mākou mau lima a manaʻo inā he kaulike ʻole paha. Inā aia, ʻo ia hoʻi ʻaʻole maikaʻi ka ʻili pae.

ʻO ia paha ʻaʻole maikaʻi nā mea papa nui a haʻihaʻi ʻia nā mea. I ka pōkole, ʻaʻole koi ʻia e kūʻai i ka mea kaulike ʻole.

ʻO ka lua, e nānā i ke ʻano o ka hierarchy o ka papa multilayer. ʻO ka mānoanoa o ka papa, ʻoi aku ka maʻalahi o ka ʻike ʻana i ka papa o ka papa multi-layer. Inā hana ʻia kēlā me kēia papa o nā mea monolithic, e mōakāka loa nā papa a ʻaʻohe hanana keʻa. Inā maikaʻi ʻole nā ​​mea, nui nā ʻōpala.

Ma muli o ka hopena o ke kaomi, e ʻoi aku ka maikaʻi o ka pae ma hope o ke kaomi ʻana o kekahi i kekahi.
