Veneer

** ʻŌlelo Aʻo Nui:** He kikokikona waihona mōʻaukala kēia, ʻaʻole he maʻamau o kēia manawa, kikoʻī ʻenehana a i ʻole manual hana. Pono e nānā ʻia nā hōʻailona, nā ana, nā ʻae, ka hoʻokaʻawale ʻana, nā mea hoʻopili a me nā waiwai ʻenehana ʻē aʻe e like me nā kūlana kūpono, nā palapala a ka mea hana a me nā koi o ka papahana.

ʻAʻole kēia kikokikona he wehewehe no kahi huahana ʻokoʻa i ka hāʻawi ʻana o Savo Kusić. ʻO ka hāʻawi ʻana i kēia manawa e kau ʻia ma nā puka makani, nā puka a me nā hoʻonā e pili ana.

Nā ʻano o ka veneer a me ka plywood

ʻElua ʻano o ka veneer: ʻoki a ʻoki ʻia. Hoʻohana ʻia ka veneer i kālai ʻia no ka hana ʻana i ka plywood no nā puka, nā papa kamanā, nā papa, nā kūkulu hale, nā lako, a me nā mea ʻē aʻe.  He ʻekolu a ʻoi aʻe paha nā ʻāpana lahilahi o ka lāʻau i ʻili ʻia i hoʻopaʻa ʻia i mea e kū pono ai nā ʻili o kekahi me nā kaula o kekahi.

Hana ʻia ka lāʻau mai ka birch, alder, lehu, elm, ʻoka, beech, linden, aspen, pine, spruce, kedera a me ka fir. Ua kapa ʻia nā ʻaoʻao o waho o ka lāʻau pāpaʻi a kapa ʻia nā papa o loko i waena. Ke like ka helu o nā papa, a laila pono e loaʻa i nā papa waena ʻelua ka ʻaoʻao fiber parallel. E pili ana i ka pale ʻana i ka wai, ua hana ʻia ka plywood me nā ʻano like ʻole: FSF plywood me ka hoʻonui ʻana i ke kūpaʻa wai, i hoʻopili ʻia me nā mea hoʻopili ʻano phenol-formaldehyde; FK a me FBA - ka plywood me ke kūpaʻa wai maʻamau, hoʻopili ʻia me ka carbamide a i ʻole albumin casein glues; Plywood FB me ka pale wai liʻiliʻi, i hoʻopili ʻia me nā glues protein. Ma muli o ke ʻano o ka hoʻoponopono ʻana i nā lau o ka ʻili, hiki ke hoʻopaʻa ʻia i ka plywood ma kekahi ʻaoʻao a i ʻole nā ​​ʻaoʻao ʻelua. Hāʻawi ʻia nā ana nui o ka plywood ma ka pākaukau.

Ana o ka Plywood

Ua ana ʻia ka lōʻihi o hoʻokahi ʻāpana lāʻau ma ke ʻano o nā ʻili o nā lau o waho. Hana ʻia ka Plywood me ka mānoanoa o 1,5; 2,0; 2,5; 3; 4; 5; 6; 8; 9; 10 a me 12 mm. ʻO ka mānoanoa liʻiliʻi loa o ka lāʻau birch a me ka lāʻau alder i hoʻoholo ʻia ʻo 1,5 mm, a me nā ʻano lāʻau ʻē aʻe - 2,5 m. Ua ʻae ʻia nā ʻokoʻa o ka plywood i hoʻopaʻa ʻole ʻia e ka mānoanoa i mm: No ka manoanoa plywood i mm 

• 1,5; 2,0 a me 2,5 - ± 0,2
• 3,0 - ± 0,3
• 4,5 a me 6,0 - ± 0,4
• 8,0; 9,0 a me 10,0 - ± 0,4 ia 0,5
• 12,0 - ± 0,6

I ka wā e hoʻoneʻe ai i ka lāʻau ʻala, ʻaʻole pono e ʻoi aku ka emi ʻana o kona mānoanoa ma kekahi ʻaoʻao (me ka noʻonoʻo ʻana i nā ʻae ʻia) ma mua o 0,2 mm, ma nā ʻaoʻao ʻelua 0,4 mm. Wahi a ka maikaʻi, hana ʻia ka veneer no ka plywood i nā ʻano penei: A, A1, AB, AB1, B, BB, C. Hāʻawi ʻia nā ʻikepili no ke koho ʻana i nā lau i ka papaʻaina. 4.

Ke koho ʻana i nā lau a me ka maikaʻi o ka gluing

ʻO nā ʻāpana lāʻau lahilahi i puʻunaue like ʻia (e like me ka mānoanoa o ka plywood) pono ke ʻano like o ka lāʻau a me ka mānoanoa like.

Plywood pono e hoʻopili paʻa ʻia, me ka ʻole o nā ʻōhū, ʻAʻole pono e hoʻokaʻawale i ka wā e kulou ana. Hāʻawi ʻia ka ikaika ʻoki hope loa i kēlā me kēia papa o ke kāpili ma ka papaʻaina.5.  

ʻO ka hāʻawi ʻana i ka plywood e like me nā ana, nā papa, nā hōʻailona, ​​​​nā ʻano o ka lāʻau, ke kuhikuhi ʻana o nā fila lāʻau i nā lau a me ke ʻano o ka hana ʻana e like me nā kikoʻī o ka mea kūʻai. Loaʻa ʻia ka lāʻau koʻa ma ke ʻano o ka lāʻau ma luna o nā mīkini kūikawā no ka hoʻopili ʻana i ka lāʻau a hoʻohana ʻia i mea uhi no nā huahana lāʻau.

Nā ʻano ʻoki ʻoki

Hoʻokaʻawale ʻia ka veneer sanded i radial, semi-radial, tangential a me tangential - mua, i loaʻa mai nā kumu lāʻau (tab.6).

Ua maheleia ka Plywood i ekolu papa e like me ka maikai o ka laau: I, II a me III. 

ʻO nā ana, ka haʻahaʻa a me ka maikaʻi hoʻopau o ka veneer

Hoʻohana ʻia ka veneer mai ka ʻoka, beech, walnut, maple, maple, lehu, elm, chestnut, sycamore, Amur velvet, pear, apple, poplar, cherry, acacia, birch, alder and hornbeam.

ʻO ka lōʻihi o ka radial, semi-radial a me ka tangential veneers hele mai 1,0 m a kiʻekiʻe; tangential - mua - mai 0,3 a ʻoi aʻe me ka piʻi ʻana mai 0,1 m.

ʻO ka mānoanoa o ka veneer no nā ʻano se - 0,8; 1,0; 1,2; 1,5 mm.

ʻAe ʻia nā ʻae ʻana mai nā ana mānoanoa i kuhikuhi ʻia (ma mm):

• No ka mānoanoa veneer 0,8 mm - ± 0,05 
• No ka mānoanoa veneer 1,0 mm - ± 0,08
• No ka mea hoolele 1,2 - 1,5 mm - ± 0,1

ʻO 10 ± 2% ka haʻahaʻa o ka veneer.

Ma ke ʻano o ka maikaʻi o ka lāʻau, pono ka veneer e hoʻokō i nā koi o ke kūlana e kū nei. Pono ka ʻili palahalaha maʻemaʻe o nā lau Veneer, me ka ʻole o ka ʻala, nā ʻōpala, nā māwae a me nā ʻili metala.
