OSB papa
ʻO ka oriented strand board (OSB) kahi ʻano lāʻau i hana ʻia e like me ka particle board, i hana ʻia me ka hoʻohui ʻana i nā mea hoʻopili a laila kaomi i nā papa o nā kaula lāʻau (flakes) i nā kuhikuhi kikoʻī.
ʻO ka OSB kahi mea me nā waiwai mechanical maikaʻi e kūpono loa ia no nā noi lawe ukana i ke kūkulu ʻana.ʻOi aku ka kaulana i kēia manawa ma mua o ka plywood, e kauoha ana i 66% o ka mākeke panel structural.ʻO nā mea hoʻohana maʻamau e like me ka sheathing ma nā paia, ka papahele, a me ka hoʻopā hale.No ka hoʻohana ʻana i ka pā o waho, loaʻa nā panela me kahi ʻāpana radiant-barrier laminated i kekahi ʻaoʻao;ʻoluʻolu kēia i ka hoʻokomo ʻana a hoʻonui i ka hana ikehu o ka envelop hale.
Manaʻo ʻia nā huahana Phenol-formaldehyde he mea pōʻino ʻole.Hoʻohana nā ʻano hou o OSB i nā resins isocyanate i loaʻa ʻole formaldehyde a manaʻo ʻia he nonvolatile ke hoʻōla ʻia.Manaʻo nā hui kālepa ʻoihana ʻo ka hoʻokuʻu ʻana o ka formaldehyde mai ʻAmelika ʻAmelika OSB he "ʻole a ʻaʻole ʻole".
ʻO nā pono o ka papa OSB
1) Ke kūkulu paʻa a me ka ikaika kiʻekiʻe
2) ʻO ka wili liʻiliʻi, decontamination a i ʻole warping
3) ʻAʻohe popopo a palaho paha, ikaika i ka ʻino a me ke ahi
4) Hōʻoiaʻiʻo wai, kūpaʻa i ka wā e ʻike ʻia ai i loko o ke ʻano kūlohelohe a pulu paha
5) Haʻahaʻa haʻahaʻa formaldehyde
6) ʻO ka ikaika nailing maikaʻi, maʻalahi ke ʻoki ʻia, kui ʻia, wili ʻia, grooved, planed, filed or polished.
7) ʻO ka wela maikaʻi a me ke kani ʻana, maʻalahi ke uhi ʻia
