ʻOka vs Birch Plywood ikaika: ʻoi aku ka ikaika no kāu kūkulu ʻana

ʻOi aku ka ikaika o ka lāʻau lāʻau Birch ma mua o ka lāʻau ʻoka

Ke nīnau mai ka mea hoʻolālā, ka mea hana hale kākela, a i ʻole ka mea hana ʻaelike inā ʻoi aku ka ikaika o ka lāʻau ʻoka a i ʻole ka birch plywood, ʻo ka pane kūpono ʻo birch - ma ka mānoanoa like, a i ka wā i hana maoli ʻia ka papa birch full-birch. ʻO ka lāʻau ʻoka paʻa ʻaʻole hiki ke hōʻole ʻia he lāʻau paʻakikī. Akā ʻo ka lāʻau ʻoka i kūʻai ʻia no nā lako, loko, a me ka hana maʻamau, he mea maʻamau ka maka ʻoka lahilahi ma luna o kahi kumu haʻahaʻa o ka poplar, pine, a i ʻole lāʻau hui ʻia. ʻO ka piha-birch plywood, ma ke ʻano like, kūkulu ʻia mai nā veneers birch i kēlā me kēia papa: ka maka, ke kua, a me ke kumu. ʻO kēlā ʻokoʻa hoʻokahi e hoʻololi kokoke i kēlā me kēia waiwai hoʻolālā e pili ana i kahi papa.

Ma nā ʻāpana 18 mm, hiki i ka lāʻau piha birch piha i kahi modulus o ka elasticity ma kahi o 12,000 N/mm² a me kahi modulus o ka haki ma kahi o 75 N/mm². He 6,800 N/mm² no ka elasticity a me 42 N/mm² no ka nahae. ʻAʻole kēia nā ʻokoʻa cosmetic. Hiki ke hoʻokaʻawale ʻia ke kai kūʻono, ʻoi aku ka liʻiliʻi o ka pale ʻana o ka papa hana ma lalo o ka ukana, a hiki ke wehe ʻia, hoʻomaʻemaʻe, a hoʻohana hou ʻia ka papa hana ma mua o ka haki ʻana o kona mau kihi.

Pono ka pane i hoʻokahi hōʻailona: "ʻoak plywood" ʻaʻole ia he huahana hoʻokahi. Inā he birch a i ʻole ke kumu lāʻau paʻa ʻē aʻe i ka papa ʻoka, hiki i kona ikaika ke hoʻokokoke piha piha. ʻO ka hoʻohālikelike kūpono ʻaʻole ia he ʻoka ma ke ʻano he ʻano kūʻē i ka birch ma ke ʻano he ʻano, akā ʻo ke kūkulu ʻana i ka ʻoka e kūʻē i ka hana piha-birch. ʻO nā mea a pau ma lalo nei e wehewehe i ke kumu o ka hoʻohālikelike ʻana i nā helu like ʻole, a pehea e hōʻoia ai i ka panel āu e kūʻai nei.

Pili ka ikaika o ka Plywood ma ke kūkulu ʻana, ʻaʻole ma luna o nā ʻano lāʻau wale nō

ʻO kahi papa lāʻau plywood kahi mea i hana ʻia. ʻAʻole ia e kulou a puʻunaue i ka ukana no ka mea ua hoʻopaʻa ʻia kēlā me kēia veneer ma kahi o 90 degere a hiki i ka mea ma lalo iho, a ua hoʻopaʻa ʻia ka waihona holoʻokoʻa ma lalo o ka wela a me ke kaomi. ʻOi aku ka liʻiliʻi o nā ʻano mea i paʻi ʻia ma ka ʻikepili ma mua o ke ʻano ma hope. ʻEhā mau mea e hoʻoholo ai i ka mea hiki ke kākoʻo maoli i kahi panel:

• ʻO ke kumu nui. ʻO nā lālā lāʻau e lawe i ka ukana. He 650 a 700 kg/m³ ka mānoanoa malo'o o nā veneer birch. ʻO Poplar, ka mea maʻamau maʻamau i nā paneli ʻoka-maka, hāʻule kokoke i 400 a 450 kg/m³. ʻO ke kumu haʻahaʻa haʻahaʻa ka liʻiliʻi o nā mea i hoʻokahi kenimika cubic e pale aku ai i ka piʻo ʻana a me ke kaomi.
• ʻO ka maikaʻi a me ka mānoanoa. Hoʻohana ʻia ka lāʻau lāʻau birch i kūkulu ʻia i ka 1.2 a 1.5 mm i nā veneers birch a puni ka hale. Hoʻohana ʻia nā panina ʻoka hoʻonaninani i ka maka ʻoka he 0.4 a 0.6 mm ma luna o nā cores i kūkulu ʻia mai ka lāʻau mānoanoa, haʻahaʻa haʻahaʻa a i ʻole nā ​​ʻāpana lāʻau paʻa. He mea liʻiliʻi ke ʻano o nā veneers maka lahilahi a palupalu i ka ʻoʻoleʻa o ka papa.
• Ka helu o nā papa kuʻekuʻe. He 18 mm ka piha-birch panel he 11 a 15 plies. Hoʻopau kēlā me kēia papa ʻāpana keʻa i ka hoʻolaha ʻana o ka māwae a hoʻemi i ka manaʻo o ka panel e kīʻaha, wili, a kolo paha ma lalo o ka ukana hoʻomau. Hoʻohana pinepine ʻia nā panela ʻoka i ka 5 a 9 wale nō i ka mānoanoa like.
• ʻO ka maikaʻi paʻa a me ke kaomi. Hoʻololi ka ʻōnaehana resin i ka ukana ma waena o nā veneers. Phenolic, melamine, a i ʻole WBP marine adhesives e mālama i ka paʻa paʻa i ka makū a me ka hoʻouka ʻana, ʻoiai e nalowale ana ka ikaika o ka urea adhesives i loko o ka piʻi ʻana o ka haʻahaʻa. ʻO ka hiki ke kūkulu ʻia e pili ana i ka paʻa, ʻaʻole ma ka lāʻau wale nō.

E noʻonoʻo i kahi papa maʻalahi. He 1,000 mm ka lōʻihi i hana ʻia mai ka 18 mm piha-birch plywood e hoʻohuli i ka liʻiliʻi ma mua o ka panel i kūkulu ʻia me ka poplar core, a hoʻi ia i kona kūlana mua ke wehe ʻia ka ukana. Ke hoʻomau nei ka ʻaoʻao birch i ka lawe ʻana i ka ukana inā e noho ana kahi paona koʻikoʻi ma kahi kokoke i ke kikowaena, no ka mea e puʻunaue ana nā veneers paʻa i ka ikaika ma nā ʻāpana he nui ma mua o ke koʻikoʻi ʻana o ka laina adhesive. ʻO ia ke kumu e hiki ai ke hoʻohana ʻia ka hana papa like e lawelawe ana i nā kupapaʻu kupapaʻu no nā papa scaffolding a i ʻole ka papahele kaʻa, ʻoiai ʻaʻole hiki ke hoʻohana ʻia nā panela i ke alo ʻoka.

He aha ka mea i kūʻai ʻia ma ke ʻano he "Oak Plywood": ʻEhā Hana Hana, ʻEhā Papa ikaika

Ma mua o ka hoʻohālikelike ʻana i ka ʻikepili hoʻāʻo, e wehewehe i ka lepili. ʻO ka lāʻau lāʻau ʻoka ma ka mākeke e hāʻule pinepine i hoʻokahi o nā hana ʻehā:

ʻO nā ʻano kumu lāʻau palupalu a me MDF-core ka mea i hoʻohālikelike ʻia me ka lāʻau birch no ka mea ʻoi aku ka nui o nā lako hale kūʻai a me nā mea hoʻonaninani o loko. Aia ko lākou mau maka ʻoka i ka helehelena, ʻaʻole ke ʻano. ʻO ka mana o ka hardwood-core he papa hana kūpono, akā i kēlā hihia ke kumu - ʻaʻole ke alo oak - e hana kokoke ana i nā hana āpau.

Helu Paʻa: ʻOka Plywood vs Birch Plywood Hōʻike Waiwai

Hōʻuluʻulu ka papa ma lalo i nā waiwai i ana ʻia no nā panela 18 mm. Loaʻa nā waiwai mai nā hōʻike hoʻāʻo maʻamau EN 636, EN 789, a me GB/T 17657 a hiki ke hoʻololi iki ʻia e ka mea hana, ka maikaʻi veneer, a me ka hoʻopili. E hoʻohana iā lākou e like me nā helu hoʻolālā, ʻaʻole ma ke ʻano he pani no ka palapala hōʻoia o ka mea hoʻolako.

Hōʻike nā pakuhi ʻelua ma lalo i nā hoʻohālikelike hoʻohālikelike koʻikoʻi mai ka papa. Hoʻohālikelike ʻia nā waiwai āpau i ka mea ikaika loa i kēlā me kēia pakuhi.

ʻElua mau manaʻo e kū nei. ʻO ka mea mua, he 45% ka liʻiliʻi o ka ʻoʻoleʻa a ma kahi o 44% ka nāwaliwali o ke kulou ʻana ma mua o ka lāʻau lāʻau piha birch ma ka mānoanoa like. ʻO ka lua, ʻoi aku ka paʻakikī o ka ʻoka keʻokeʻo paʻa ma mua o ka lāʻau birch, akā ʻo ka hoʻohālikelike ʻana i nā panela he plywood me ka plywood. Inā makemake ʻoe i ka ikaika oak ʻoiaʻiʻo i loko o kahi huahana lau, pono ka panel i kahi kumu lāʻau paʻa, ʻaʻole he alo ʻoka wale nō.

He aha ke ʻano o kēlā me kēia waiwai ikaika ma kahi papahana maoli

He mea nui wale nā helu hoʻāʻo ke unuhi ʻia i loko o ke ʻano i ʻike ʻia ma ka pūnaewele a i ʻole ka hale hana. Eia ke ʻano o nā ʻokoʻa ma luna no ka hoʻohana ʻana i kēlā me kēia lā.

Loaʻa pū kekahi pono ikaika-i-kaumaha. ʻOi aku ka māmā o ka lāʻau lāʻau birch piha ma 680 kg/m³ i kēlā me kēia mika square ma mua o ka lāʻau ʻoka paʻa, akā ʻoi aku ka ʻoi aku o kona ʻoʻoleʻa i kēlā me kēia kilokika ma mua o kēlā me kēia papa kumu lāʻau palupalu. Hoʻohui pū ʻia me ke kūpaʻa dimensional mai ka cross-band, pili kēia mea kaumaha i nā ʻāpana prefabricated i hāpai ʻia me ka lima, ma nā puka keʻena e pono e noho palahalaha ma luna o nā ili nui, a ma ka lawelawe ʻana i nā mea kahi e pili pono ai ke kaumaha o ka panel i ke kumukūʻai hoʻonohonoho.

Inā ʻoe e ʻōlelo nei no kahi noi hoʻolālā a i ʻole semi-structural, e nānā i ka MOE a me MOR o ka panel ma mua o ka hilinaʻi ʻana i ka lepili ʻano maka. Mālama ka MOE kiʻekiʻe i ka panel ma lalo o ka ukana; ʻO kahi MOR kiʻekiʻe e pale aku i ka hāʻule ʻole ʻana. ʻOi aku ka manaʻo o nā mea ʻelua i ka hana piha-birch ma mua o nā panela i hoʻonani ʻia i ka ʻoka. No ka loiloi ʻaoʻao i kahi e ʻike ʻia ai kēia mau mea maikaʻi, e ʻike i ka nā pono ʻenehana o ka plywood birch i ka ikaika a me ka paʻakikī i hoʻohālikelike ʻia me nā lāʻau ʻē aʻe .

Kahi e hōʻike ʻia ai ka pōmaikaʻi ikaika o Birch Plywood i ka hoʻomaʻamaʻa

ʻOi aku ka maʻalahi o nā pono kūpono o ka birch plywood i nā noi kikoʻī i kēlā me kēia lā:

• ʻO nā kupapaʻu a me nā papa lako. Hoʻopaʻa nā paneli piha piha i nā wili hinge ma hope o nā makahiki o ka wehe ʻana a me ka pani ʻana, e kūʻē i ka hāʻule ʻana o ke keʻena ma nā ʻaoʻao ākea ākea, a me ka mīkini maʻemaʻe no nā hui dowel, biscuit, a me domino. Hoʻopuka pū ke kumu ʻaʻahu i ka hoʻopaʻa ʻana i nā lihi kūʻokoʻa a me ka liʻiliʻi o ka haehae ʻana a puni nā awāwa i hele ʻia.
• Nā papa hana a me nā lako hana. He 27 mm a i ʻole 30 mm ka papa hana birch e paʻa paʻa ma lalo o ke kaomi ʻana, lawe i ka hāmare kaumaha me ka ʻole o ka haki ʻana, a hiki ke alo hou ʻia me ka ʻili ʻana me ka wehe ʻole ʻana i nā hakahaka. ʻO nā panela lāʻau palupalu ʻoʻaʻa e pili ana i nā ʻīlio noho a me nā ʻauwae hope, a me nā hakahaka ma ke kelepona nui ma hope o kekahi mau makahiki o ka hoʻohana ʻana i ka hale hana.
• Paʻa paʻa. He koho maʻamau no nā kolamu, nā paia, a me nā ʻaoʻao pāpaʻi no ka mea ʻoi aku ka maikaʻi o ka haʻalulu ʻana o ke kumu birch paʻa i ka wā o ka hoʻokomo ʻana a ola mau i ka wehe ʻana a me ka hoʻomaʻemaʻe. ʻO nā helu hoʻohana maʻamau mai ka 20 a hiki i ka 40 a ʻoi aʻe ka ninini ʻana me ka mea hoʻokuʻu kūpono a me ke sila ʻana o ka lihi, ʻoiai ʻo nā paneli puka kumu lāʻau palupalu e hoʻomaka maʻamau i ka delaminate ma nā ʻaoʻao ma mua.
• Nā papahele halihali a me nā papa ukana. Hoʻohana ʻia ka lāʻau lāʻau Birch i nā moena kaʻa, nā hale kaʻahele, a me ka papahele pahu ma 21 a 27 mm ka mānoanoa no ka mea e hui pū ana i ka ikaika piʻi kiʻekiʻe me ke kūʻē ʻana i nā ukana mai nā wāwae pallet, nā huila forklift, a me nā lako paʻa.
• CNC milling a me ka ʻoki ʻana i ka laser. ʻOki ʻokiʻoki birch paʻa, ʻaʻohe kīnā ʻole me kahi ʻaoʻao maʻemaʻe. No ka hana laser, ʻo ke ʻano like ʻole o nā veneers birch e mālama i ka laula kerf a me ka wikiwiki o ka ʻoki ʻana, ʻo ia ke kumu e kuhikuhi ai nā mea hoʻohālike kikoʻī a me nā hale kūʻai make-papa i ka birch ma mua o nā panela composite i ke alo oak.

ʻO ka Plywood Birch Premium me ka B/BB maʻemaʻe a me ka S/BB No ka hale keʻena ʻike ʻia a me ka hoʻopau ʻana, hāʻawi kēia ʻano lāʻau birch kiʻekiʻe i kahi maka one maʻemaʻe me ka ikaika like ʻole, kūpono no nā lako a me nā hana o loko. Nānā Huahana →

No nā maka keʻena a me nā keʻena keʻena i ʻike ʻia, hāʻawi nā panela birch kiʻekiʻe me B-BB a i ʻole S-BB i ke ʻano kumu like me ka lāʻau lāʻau birch ʻoihana me ka hāʻawi ʻana i kahi maka maʻemaʻe a me ke one no ka pena pena ʻana, a i ʻole ka hoʻopau ʻana. No ka hana kūkulu ʻana i ke kūlana kiʻekiʻe o ka helehelena, loaʻa ke kūkulu ʻia ʻana o ka panel ma nā papa waena ma ke kumu kūʻai haʻahaʻa.

ʻO ka Plywood Birch Kiʻiʻoniʻoni no ka maʻu a me nā noi waho ʻO kēia lāʻau lāʻau birch pale i uhi ʻia e kūʻē i ka wai a me ka ʻaʻahu, e hana ana ia i ke koho i manaʻo ʻia no ka formwork, hoardings, a me nā kūlana ʻike koi ʻē aʻe. Nānā Huahana →

Ke komo ka ʻoihana i ka makū, ka lepo, a i ʻole ka hoʻolaha ʻana i waho, hoʻohui ʻia ka lāʻau lāʻau birch kiʻi ʻoniʻoni i ke kumu kiʻekiʻe like me ka phenolic a i ʻole ka melamine overlay e kūʻē i ka hoʻoheheʻe ʻana i ka wai, ka hoʻouka kemika, a me ka ʻaʻahu o luna. ʻO kēlā hui ʻana ka pane maʻamau no ka formwork, hoardings, a me nā hale kūwaho waho.

Ke Kūʻai ʻoi aku ka maikaʻi o ka lāʻau ʻoak

Ua lanakila ʻo Birch ma ke kūkulu ʻana, akā ʻaʻole kakaikahi ke koho ʻana i ka plywood e pili ana i ka hale wale nō. ʻOi aku ka maikaʻi o nā panela o ka alo i nā ʻano he nui:

• Nā papahana hoʻonanea. Hāʻawi ʻo ʻOak veneer i nā ʻano huapalaoa i ʻōlelo ʻia i nā kiʻi ʻoka keʻokeʻo, ʻoka ʻulaʻula, a me nā kiʻi i ʻoki ʻia. He ʻoi aku ka māmā o ka leo Birch, ʻoi aku ka lōʻihi o ka leo me kahi huaʻai mālie. Ke hōʻike nei ka pōkole hoʻolālā i kahi aesthetic oak, ʻaʻole hiki ke hoʻololi ʻia ka birch me ka ʻole o ka veneering.
• ʻO ka pale ʻana i ka paia a me nā mea lako i mua. ʻO nā panela e ʻoki ʻia i loko o nā puka, fascias, a i ʻole nā ​​​​panela paia a noho ma lalo o nā haʻahaʻa māmā ʻaʻole pono ke kumu hoʻolālā. ʻO kahi papa ʻoka me kahi kumu lāʻau palupalu ma 12 a i ʻole 15 mm e ʻoi aku ka māmā o ka papahana.
• ʻO ka hana hoʻoponopono kālā. Inā pena ʻia, uhi ʻia, a hoʻololi ʻia paha ka paneli i loko o kekahi mau makahiki, ʻaʻole kūpono ka uku ʻana i kahi kumu birch piha. Hiki ke ʻae ʻia nā panela me ka poplar maʻemaʻe no ka lawe ʻole ʻana i ka ukana.
• Kahi e pono ai ka helehelena a me ka ikaika. Hoʻohui ʻia nā panela birch-core o ka alo o ka ʻoka i ka nani oak me ka hana ʻana o ka birch. Ua kūʻai ʻia lākou ma waena o nā paneli piha piha a me nā panela oak-core, a ʻo ia ka kikoʻī pololei inā ʻike ʻia ka hua ʻoka a me ka ikaika wānana ma ka papa inoa koi.

Pehea e hōʻoia ai i ka ikaika o ka Panel ma mua o kou kauoha

Hoʻomaka ka nānā ʻana me ka ʻikepili, ʻaʻole me ka maka panel. ʻO ka papa inoa ma lalo nei e kōkua i ka pale ʻana i nā hewa kikoʻī maʻamau:

1. E hōʻoia i ka ʻano kumu ma ke kākau ʻana. E noi i ka mea hoʻolako e hōʻike i ke ʻano kumu ma ka ʻōlelo a i ʻole ka ʻikepili ʻenehana. "ʻOak plywood" me ka ʻole o kahi kikoʻī kikoʻī ʻaʻole lawa ka ʻike no kahi papahana hoʻolālā.
2. E helu i nā pā ma ka ʻaoʻao o ka panel. He 11 a ʻoi aʻe paha nā veneers ma kahi papa piha-birch maoli 18 mm. He 5 a 9 ka mānoanoa like o ka mānoanoa o ka lāʻau ʻoʻa maka.
3. E nānā i ka papa hoʻopili. No ka loko maloʻo, ʻoi aku ka liʻiliʻi o nā mea hoʻopili urea i loko akā kūpono ke ʻano. No nā lako, ka lawe ʻana, a me ke kūkulu ʻana, e kuhikuhi i ka WBP, phenolic, a i ʻole melamine adhesive, a i ʻole kahi panel i hōʻoia ʻia i ka papa EN 314-2 3. Hōʻike koke nā pōʻai wai i nā paʻa nāwaliwali.
4. E hōʻoia i ka nui ma ka ʻikepili. Pono e hōʻike ka lāʻau lāʻau birch i ka nui o ka panel ma kahi o 650 a 720 kg/m³. Inā hōʻike ka ʻikepili ma lalo o 600 kg/m³ i ka wā i kapa ʻia ai ka huahana "birch", ua hui pū ʻia ke kumu me ka lāʻau palupalu. Ma muli o ka hoʻokumu ʻana o ke kino i ka ikaika, ʻo ka mismatch density kahi hōʻailona hōʻailona.
5. E noi i nā hōʻike hoʻāʻo kūlou. EN 789, GB/T 17657, a i ʻole ASTM D1037 hōʻike e hāʻawi i nā waiwai MOE a me MOR maoli. Hiki i ka mea hoʻolako hana i ka lāʻau lāʻau birch structural ke hoʻolako i kēia mau mea me ka kali ʻole. E mālama i ka hōʻike no ka mālama ʻana i ka maikaʻi ma ka lawe ʻana.
6. E hoʻohālikelike i ka pae ʻili i ka hoʻohana hope. Hoʻopili ʻia nā maka B-BB a me S-BB i ke one, paʻi ʻia, a kūpono hoʻi no nā keʻena keʻena ʻike ʻia. ʻO BB-BB a me BB-CP nā māka hana maʻamau me nā hemahema liʻiliʻi i ʻae ʻia. ʻO CP-CP a me nā haʻahaʻa haʻahaʻa no nā noi ʻoihana, hale kūʻai, a huna paha. ʻAʻole hoʻololi ka papa hiʻohiʻona i ka ikaika kumu, akā hoʻololi nui ia i ke kumukūʻai.

ʻO Birch Plywood no nā papahana kūkulu hale kūʻai I ka lua o ka helehelena maka, hāʻawi kēia mau panela BB/BB a me BB/CP i ka kūpaʻa birch hilinaʻi ma ke kumukūʻai haʻahaʻa, kūpono no nā noi kūkulu huna a me ka hoʻohana ʻana i loko. Nānā Huahana →

Hoʻokahi hoʻomaʻamaʻa ʻē aʻe e pale i nā hewa he nui: ʻo ka ʻokoʻa ma waena o ka lāʻau lāʻau piha piha a me ka lāʻau combi-birch. Hoʻohana nā panela hui-birch i nā maka birch ma luna o kahi mea palupalu i loko, e hoʻohaʻahaʻa ana i ke kumukūʻai akā e hōʻemi ana hoʻi i ka ikaika mechanical. Inā pili ka papahana i nā waiwai ikaika ma kēia ʻatikala, e kuhikuhi i ka hana piha-birch ma mua o ka hui ʻana. A piha-birch vs combi-birch hoʻonaʻauao ʻoihana hōʻike pololei i ka nui o ka hoʻopili ʻana o nā papa o loko i ka hana o ka panel.

ʻOka vs Birch Plywood: Nīnau pinepine ʻia

ʻO ke koho o ka laina lalo no ka ikaika

Ke lawe ka panel i ka haawe, pale i ka hopena, paʻa i ka lakohana, a i ʻole ke kū ʻana i ka lawelawe pinepine ʻana, e kuhikuhi i ka lāʻau lāʻau birch piha a hōʻoia he birch ke kumu mai ka ʻikepili. Ke loaʻa mua ka panel e hōʻike i kahi hua ʻoka, ua ʻae ʻia kahi papa ʻoka - akā ʻaʻole e hoʻololi ka ikaika o ka ʻoka paʻa i kahi panel me kahi kumu lāʻau palupalu. E nānā i ke kumu, e helu i nā plies, e hōʻoia i ka papa adhesive, a noi i nā waiwai hoʻāʻo ma mua o ke kauoha ʻana. Hoʻopau kēlā kaʻina i nā kumu maʻamau o ka hāʻule ʻana o nā pale, nā ʻūlū hāʻule, a me ka hemahema o ka hana mua.
