He aha ka plywood?
Nā mea
ʻO nā papa lāʻau a i ʻole "pepa" he ʻekolu a ʻoi aʻe paha nā ʻāpana lahilahi o ka lāʻau maoli i hoʻopili ʻia.
Ua kapa ʻia nā papa he "layers", no laila ka inoa "plywood". E like me ke kānāwai, ʻoi aku ka mānoanoa o ka plywood, ʻoi aku ka nui o nā papa.
He mea maʻalahi ia me ka nui o nā noi, mai ka pā a me ka uhi papahele a hiki i nā ʻōpala paʻa, nā lako mea hoʻolālā a me ka hoʻopili.
ʻOi aku ka ikaika o ka lāʻau lāʻau ma mua o kekahi mau mea lau ʻē aʻe e like me ka medium density fibreboard (MDF).
E ʻike i kā mākou ʻaoʻao He aha ka MDF?, no ka 'ike hou aku ma Medium Density Fibreboard.
ʻO ka ikaika o ka plywood ma muli o ke ʻano o ke kuhikuhi ʻana o nā fiber o kēlā me kēia papa e pili ana i nā papa pili.
ʻO ka hoʻololi ʻana o ka ʻaoʻao palaoa o kēlā me kēia papa, i kapa ʻia ʻo ka palaoa keʻa, he 90 degere (he kihi ʻākau). ʻO ia ke ʻano o ka ʻai o kēlā me kēia ʻāpana i ka ʻaoʻao hoʻokahi, a ua hoʻonohonoho ʻia ka papa ma kahi kihi 90 degere ma waena o lākou. Eia nō naʻe, hiki i ke kihi o ka huli ʻana ke haʻahaʻa i 30 degere. I kekahi mau plywood mānoanoa, hiki ke hoʻonohonoho ʻia ʻehiku papa ma ke kaʻina ma nā kihi o 0, 30, 60, 90, 120, 150, a me 180 degere).
He nui nā pōmaikaʻi o ka rotating grain. ʻO kēia:
Hoʻemi i ka manawa o ka māhele ʻana i ka wā e kui ʻia ai nā lau i nā kihi
Hoʻemi i ka hoʻonui a me ka hoʻohaʻahaʻa ʻana no ke kūpaʻa ʻoi aku ka maikaʻi
Hāʻawi ka plywood i ka ikaika paʻa i nā ʻaoʻao āpau a puni ka papa.
He Moolelo Pokole no ka Plywood
ʻYplelo kahiko
ʻO nā huahana lāʻau i hana ʻia ma ʻAigupita kahiko ma kahi o 3500 BC ʻo ia nā hiʻohiʻona mua loa o ka hoʻohana ʻana i ka plywood. Hana ʻia lākou mai ka ʻili ʻili i hoʻopaʻa ʻia i ke keʻa, e like me ka plywood hou.
Kina, ʻEnelani a me Farani
Ma kahi o 1,000 makahiki aku nei, Ua hoʻolālā ka Pākē i ka lāʻau a hoʻopili ʻia e hana i nā lako.
Ua hana nā Pelekāne a me Palani i nā paneli ma ke kumu maʻamau mai ka plywood i nā kenekulia 17 a me 18.
Mai ka hale a hiki i ke kūkulu ʻana
ʻO nā hiʻohiʻona mua o ka plywood, ka mea maʻamau i hana ʻia mai nā lāʻau paʻa hoʻonaninani, i hoʻohana pinepine ʻia i ka hana ʻana i nā mea hale e like me nā keʻena keʻena, nā pahu, nā countertops, a me nā puka.
Ua ʻike ʻia ka lāʻau palapaʻa palupalu no ke kūkulu ʻana i ke kenekulia 20.
He aha ka mea i hoʻohana ʻia?
Nui o nā noi
ʻO ke ʻano o ka hoʻohana ʻana i ka lāʻau plywood, i loko a i waho, ʻike ʻia he pau ʻole. I ke kūkuluʻana, hiki ke hoʻohanaʻia i nā paia, nā papahele, nā kaupaku a me nā alapiʻi; ma ke ʻano he formwork (ʻano o ke ʻano) e hoʻopaʻa ʻia i ka wā e hoʻonohonoho ai; a i loko o kahi kiʻi no ka hoʻomoe ʻana i nā pōhaku lepo a i ʻole nā pohaku i ka wā e hoʻonohonoho ai i nā puka pio.
Nā lako
Hoʻohana nui ʻia ka Plywood i ka hana hale.
Hoʻopili ʻia, hoʻohālike a me nā ʻili kiʻi
ʻO nā noi ʻē aʻe e pili ana i ka ʻeke paʻa, nā hāmeʻa a me nā mea pāʻani, a me nā kino o kekahi mau kaʻa a me nā mokulele māmā.
Hoʻohana pinepine ʻia ka lāʻau ʻeleʻele i ka hana hoʻohālike, a pena kekahi poʻe pena kiʻi ma hope o ka uhi ʻana iā ia me ka plaster, kahi mea hoʻopaʻa e hāʻawi ai i kahi ʻili ʻāʻī e paʻa pono ai i ka pena.
Hoʻolālā ʻia no nā kumu kūikawā
Hoʻolālā ʻia nā ʻano lāʻau plywood no nā kumu kikoʻī. No ka la'ana, ua ho'ohana 'ia ka plywood ikaika i hana 'ia mai ka mahogany a/a i 'ole ka birch i ka hana 'ana i kekahi mau mokulele o ke Kaua Honua II, a 'o ka plywood moana i hana 'ia mai ke alo ikaika a me loko o ka veneers me ka li'ili'i o nā hemahema, 'oi aku ka maika'i o ka hana 'ana ma ka pulu a me ka wai.
Nāʻano
Nā pūʻali koa
He ikaika ka Plywood, maʻamau ka pale ʻana i ka pōʻino, maʻalahi, a maʻalahi hoʻi e ʻoki a "hana" me nā mea hana.
He mea maikaʻi loa ia ma ke ʻano he lau no ka hana ʻana a uhi ʻana paha i ka nui, pālahalaha, sloping a i ʻole nā ʻano like ʻole e like me nā paia, nā papahele, kekahi ʻano o nā hale a me nā ipu nui.
Pono no ka hana paʻakikī
ʻO kekahi mau ʻano o ka lāʻau paʻa he kūpono ia no ka hana paʻakikī, e like me ka hana ʻana i nā hiʻohiʻona, nā puʻupuʻu lāʻau, a me nā pahu liʻiliʻi.
Hoʻopili koke nā paneli nui i nā wahi nui
Ma muli o ka loaʻa ʻana o ka lāʻau plywood i nā panela nui, hiki ke uhi ʻia nā wahi nui me ka liʻiliʻi liʻiliʻi o ka hoʻohui ʻana, a ʻo ke koho ākea o nā mānoanoa e kūpono ia no nā ʻano noi like ʻole mai ka papa manoanoa a hiki i ka pale lahilahi.
Pehea i hana ʻia ai ka lāʻau plywood?
No ka hana 'ana i ka plywood, 'o ia ho'i nā lā'au i kapa 'ia 'o "hullers" 'oi aku ka nui o ke anawaena a 'oi aku ka pololei ma mua o ka lā'au ma'amau i 'oki 'ia ai ka lā'au.
Wehe ʻia ka ʻili ma mua o ka wela ʻana o ka mea ʻili a hoʻomoʻi ʻia no 12 a 40 mau hola ma mua o ka ʻoki ʻana.
A laila kau ʻia i loko o kahi mīkini peeling nui a hoʻohuli ʻia a puni kona axis lōʻihi ...
… ʻoiai e hoʻokaʻawale ka lau lōʻihi i kahi lau a i ʻole ka papa mai ka lāʻau. 
Ua ʻoki ʻia ka pepa lōʻihi i nā ʻāpana o ka lōʻihi a me ka laulā mua, a nānā ʻia nā ʻili no nā hemahema. 
Hoʻopili ʻia nā papa a hoʻopili pū ʻia, a ʻoki ʻia nā papa hopena i ko lākou mau ʻāpana hope.
ʻO ka hana hope loa ʻo ia ka wili - leveling - papa. Ua uhi ʻia kekahi mau papa (e like me ka melamine a i ʻole acrylic) a ua hoʻopaʻa ʻia ko lākou mau ʻaoʻao.
He aha nā ʻano o ka plywood?
Nui loa ka laula o ka plywood. Eia kekahi o nā ʻano nui i loaʻa. E kamaʻilio me kāu mea kūʻai hale kūkulu hale a nānā paha ma ka pūnaewele inā ʻoe e ʻimi nei i kahi mea kikoʻī loa e hoʻokō i kahi pono kikoʻī.
Plywood coniferous
He ʻano maʻamau kēia o ka plywood i hoʻohana nui ʻia i ke kūkulu ʻana a me nā noi ʻoihana.
Plywood lāʻau paʻa
ʻOi aku ka ikaika a me ka rigidity o kēia ʻano. ʻO kona kū'ēʻana i kaʻino a me kaʻaʻahu e kūpono ia no nā kaiapuni paʻakikī e like me nā papahele a me nā paia.
lāʻau lāʻau pāpū
Hana ʻia mai ʻAsia, ʻApelika a me ʻAmelika Hema, ʻoi aku ka maikaʻi o kēia plywood ma mua o ka lāʻau palupalu ma muli o kona ikaika nui a me ka palahalaha o nā plies. ʻO ia ka koho i makemake nui ʻia e nā mea he nui i ka ʻoihana kūkulu. ʻO kekahi mau hiʻohiʻona he hiʻohiʻona maikaʻi loa a me ka waihoʻoluʻu, kūpono lākou no ka hoʻohana ʻana i kekahi ʻano mea lako.
Pākē kaʻino
Hana ʻia mai ka mahogany a i ʻole birch, a pinepine nā mea ʻelua, ua hoʻopili ʻia kēia plywood ikaika kiʻekiʻe me kahi mea hoʻopili e kūpaʻa loa i ka wela a me ka wai. Ua hoʻohana ʻia no kekahi mau mokulele i ka wā o ke Kaua Honua II a hoʻohana ʻia i kēia lā i nā ʻano noi like ʻole e koi ana i ka ikaika like a me ka lōʻihi.
Plywood kāhiko
He papa lāʻau paʻakikī maikaʻi kēia no ka hoʻohana ʻana i nā lako, ka pā a me nā noi "kiʻekiʻe" ʻē aʻe. ʻO nā ʻano ʻano ʻē aʻe o ka papa waho hoʻonaninani ʻo ia hoʻi ka mold a me ka resin impregnated pepa.
plywood hikiwawe
Ua ho'ohana 'ia ka plywood ma'alahi, i kekahi manawa i kapa 'ia he "hat plywood" ma muli o kona ho'ohana 'ana i nā pāpale "chimney" i ka wā Victorian, no ka hana 'ana i nā ki'i pi'o.
lāʻau lāʻau kai
ʻO ka plywood moana, e like me kona inoa e hōʻike nei, ʻo ia ke koho no nā waʻa a me nā noi ʻē aʻe he nui kahi e kū ai nā kūlana pulu a pulu. He kūpaʻa ia i ka hoʻouka kaua a me ka delamination - i ka wā e hoʻomaka ai nā papa e delaminate, ma muli o ka ʻike ʻana i ka dampness. ʻO ka ʻaoʻao haʻahaʻa, ʻoi aku ka nui o ke kumukūʻai ma mua o nā ʻano lāʻau plywood ʻē aʻe.
Plywood pale ahi
ʻO kēia ka lāʻau plywood i mālama ʻia me nā kemika e hoʻonui ai i ke kūpaʻa ahi.
Plywood laminated me phenol
Hoʻoheheʻe ʻia ka laminate wela ma luna o ka ʻili o kēia plywood. A laila hiki ke waiho paheʻe ka ʻili no ka hana hana—e laʻana, he poʻi no nā hale paʻa a i ʻole kahi hale kūʻokoʻa e paʻa ai i nā pā pōhaku a me nā ʻano ʻano ʻē aʻe a hiki i ka hoʻonohonoho ʻana o ka mortar-a i ʻole ke kaomi ʻia i loko o ia mea no ka paheʻe ʻole a i ʻole ka hoʻonaninani. hoʻopau. Nā noi.
He aha nā nui i loaʻa?
ʻO ka nui a me ka liʻiliʻi liʻiliʻi e hilinaʻi pinepine ʻia i ke ʻano o ka plywood, akā ʻo ka nui maʻamau maʻamau ʻo 4ft a 8ft (1220mm x 2440mm). Loaʻa pinepine ʻia nā pepa nui a liʻiliʻi, maʻamau i ka hoʻonui 1 kapuaʻi (300 mm).
'Oko'a ka mānoanoa o ka lā'au mai ka 1/16" (1.4mm) a i ka 1" (25mm), 'oiai aia nā pepa mānoanoa no kekahi mau noi kūikawā.
Pehea e hoʻokaʻawale ʻia ai ka lāʻau plywood?
Hoʻokaʻawale ʻia nā ʻano lāʻau like ʻole, ma muli o ke ʻano o ka lāʻau i hana ʻia mai lākou a i ʻole ka ʻāina kumu. ʻO ka loiloi e pili ana i ka maikaʻi o ka lāʻau i hoʻohana ʻia, inā he liʻiliʻi a he nui paha nā hemahema i hoʻokahi a i ʻole nā papa ʻelua a ʻelua paha, a inā ua wehe ʻia kekahi mau hemahema i ka wā o ka hana ʻana.
No ka laʻana, nā pahu lāʻau birch:
Papa S (kiʻekiʻe) - nā mea liʻiliʻi wale nō a me nā hiʻohiʻona
Papa BB (medium) - hoʻokomo ʻia nā ʻāpana oval i hoʻololi i nā puʻupuʻu nui a me nā hemahema.
Papa WG (lalo) - wehe ʻia nā kīnā ma nā puʻupuʻu liʻiliʻi me kekahi mau puʻupuʻu nui i hoʻoponopono ʻia.
Papa C (haʻahaʻa) - ʻae ʻia nā hemahema hāmama
Aia pū kekahi ʻo Brazilian, Chilean, Finnish, Russian, Swedish a me nā ʻano ʻē aʻe. Ma mua o ke kūʻai ʻana, e nānā i ka papa lāʻau e hōʻoia i ka hoʻokō ʻana o ka lāʻau i nā koi no ka hana.
He aha nā kūlana no ka plywood?
Aia nā kūlana like ʻole - ʻEulopa a me BS (British Standards) - no ka plywood i hoʻohana ʻia i nā ʻano hana like ʻole.
No ka laʻana, i ka ʻoihana kūkulu, ʻo ke kūlana ʻEulopa no nā paneli kumu lāʻau EN 13986 e koi i ka plywood i hoʻohana ʻia i ka ʻoihana kūkulu e hālāwai me kekahi o nā papa hana ʻekolu i loko o EN 636, a pono nā mea hoʻolako e hāʻawi i ka hōʻoia o kēia.
Hoʻokumu ʻia nā papa hana i ke kūpaʻa ʻana o ka wai o ka lāʻau i hoʻohana ʻia i nā ʻāpana like ʻole o nā hale e like me nā hale, nā ʻāpana, nā papahele, a me nā paia o waho i kālai ʻia i ka lāʻau.
Hoʻohui kekahi mau ʻano i ke kūpaʻa maikaʻi o ka wā a me nā waiwai ikaika o waho e hoʻokō i nā kūlana kikoʻī e like me BS 1088 (plywood no ka hoʻohana ʻana i ke kai), aʻo ke code standard structural BS 5268-2:2002 pili i ka ikaika plywood, i hoʻohana ʻia i ka hana hana. He manaʻo maikaʻi ia e nānā inā ʻo ka lāʻau paʻa āu e kūʻai nei he maʻamau kūpono ia no ka hoʻohana ʻana.
