ʻO OSB (OrientedStrandBoard) kekahi ʻano lāʻau i hana ʻia e like me ka papa ʻāpana, ma ka hoʻohui ʻana i nā ʻāpana o nā kaula lāʻau (flakes) i kahi ʻano kikoʻī e hana i kahi mea hoʻopili a laila kaomi i ka lāʻau.
Ua hana ʻia i ka makahiki 1963 e Armin Elmendorf o Kaleponi. Hiki i ka OSB ke ʻano ʻano ʻokoʻa a ʻokoʻa ka ʻili, me nā ʻāpana pākahi ma kahi o 2.5 knm x 15 cm (1.0 x 5.9 in) i kau ʻole ʻia ma waena o kekahi, a ma nā ʻano like ʻole a me nā mānoanoa.

Ke kumu o OSB

ʻO ka OSB kahi mea me nā waiwai mechanical maikaʻi, kūpono loa ia no nā noi haʻahaʻa i ke kūkulu ʻana.
ʻOi aku ka kaulana i kēia manawa ma mua o ka plywood, ʻo ia ka 66% o ka mākeke panel structural. ʻO ka hoʻohana maʻamau e like me ka sheathing no nā paia, nā papahele a me nā pā hale.
No ka hoʻohana ʻana i ka pā o waho, hiki ke hoʻopaʻa ʻia nā panela me kahi pale kukui ma kekahi ʻaoʻao; maʻalahi kēia i ka hoʻokomo ʻana a hoʻomaikaʻi i ka hana ikehu o ka envelop hale. Hoʻohana ʻia ʻo OSB i ka hana hale.

Ka hana ʻana i nā Papa OSB

ʻO nā ʻano resins adhesive i hoʻohana ʻia e OSB: urea-formaldehyde (OSB type 1, non-structural, non-waterproof); nā mea hoʻopili isocyanate (a i ʻole PMDI polymethylene diphenyl diisocyanate-based) ma nā wahi o loko me ka melamine-urea-formaldehyde a i ʻole phenol-formaldehyde Resin glue ma ka ʻili (OSB type 2, structural, surface waterproofing); phenolic resin (OSB ʻano 3 a me 4, ʻano hoʻolālā, no nā kaiapuni wai a me waho).

Hoʻokumu ʻia nā papa ma ka ʻoki ʻana i ka lāʻau i loko o nā ʻāpana i pale ʻia a laila hoʻonohonoho ʻia ma ke kāʻei a i ʻole ka uea. Hana ʻia nā cushions ma kahi laina molding. Hoʻopili ʻia nā papa lāʻau o ka ʻaoʻao o waho me ka axis ikaika o nā panela, ʻoiai ʻo ka ʻaoʻao o loko e kū pololei. ʻO ka helu o nā papa i kau ʻia ma kahi ʻāpana o ka mānoanoa o ka panel, akā ua kaupalena ʻia e nā mea hana i hoʻokomo ʻia ma ke kahua hana. Hiki ke ʻokoʻa ka mānoanoa o kēlā me kēia papa no ka hāʻawi ʻana i nā mānoanoa panel i hoʻopau ʻia (ma ka maʻamau, ʻo kahi papa he 15 knm (5.9 in) e hāʻawi i ka mānoanoa panel 15 mm (0.59 in). Hoʻokomo ʻia ka moena i loko o kahi paʻi wela e hoʻopaʻa i nā ʻili a hoʻopaʻa iā lākou ma ka hoʻōla ʻana a me ka hoʻōla ʻana i ka resin i uhi ʻia ma nā ʻāpana. A laila ʻoki ʻia nā panela pākahi mai ka moena a hiki i ka nui i hoʻopau ʻia. Hana ʻia ka hapa nui o ka OSB o ka honua i nā hale hana nui ma United States a me Kanada.

Nā Huahana Pili

Ua hoʻohana ʻia nā mea ʻē aʻe ma waho o ka lāʻau e hana i nā huahana like me OSB. ʻO ka papa mauʻu i kūkulu ʻia he papa ʻenekinia i hana ʻia ma ka ʻoki ʻana i ka mauʻu, hoʻohui i ka P-MDI adhesive, a me ke kaomi wela i ka papa mauʻu ma kahi kuhikuhi kikoʻī. Hiki ke hana ʻia ka papa liʻiliʻi mai ka bagasse.
