ʻO wai ka maikaʻi: ka papahele ʻohe a i ʻole ka papahele lāʻau?

Papa ʻohe ʻoi aku ka maikaʻi o ke kaiapuni ma mua o ka papahele lāʻau.

Loaʻa i ka ʻohe nā waiwai mālama i ka ikehu a me ke kaiapuni, e wehe pono ana i nā mea ʻino mai ka lewa a hoʻomaikaʻi i ka maikaʻi o ka ea i loko. Hiki i ka ʻohe ke oʻo i 4-6 mau makahiki, ʻoiai he 60-kapuaʻi ka lāʻau i 60 mau makahiki e ola hou ai, ʻo ia hoʻi, hoʻokahi kumu lāʻau liʻiliʻi no kēlā me kēia lāʻau i hoʻohana ʻia. He 59 lā wale nō ka lōʻihi o ka lāʻau ʻohe. ʻO ka hoʻohana ʻana i ka papahele ʻohe kōkua e hōʻemi i ka hoʻohana ʻana i ka lāʻau, e hāʻawi ana i kahi hana pili i ke kaiapuni e pili ana i ka hoʻohana ʻana i nā kumuwaiwai o ka honua. ʻO ka papahele lāʻau paʻa e ʻae ʻia e kaohi ʻia e nā kumu waiwai a lilo i mea waiwai no ka liʻiliʻi o nā kānaka. ʻO nā huahana ʻohe nā huahana ʻōmaʻomaʻo pili i ke kaiapuni; ʻO ka hoʻohana ʻana i ka ʻohe ma kahi o ka lāʻau he hana kūpono ia e pale ai i nā kumulāʻau ulu lāʻau.

ʻOi aku ka maikaʻi o ka papahele ʻohe ma mua o ka papahele lāʻau.

ʻO ka ʻohe he kumu waiwai hou, ʻoiai ʻo ka lāʻau paʻa he kumu waiwai ʻole ia. ʻO ka hoʻonui ʻana i ka hoʻohana ʻana i ka papahele ʻohe he mea maikaʻi no ka mālama ʻana i ke kaiapuni. ʻOi aku ke kumukūʻai o ka papahele lāʻau hiki ʻole ke hoʻololi hou ʻia ma mua o ka papahele ʻohe. Ke kū nei ʻo Kina i ka hemahema o ka lāʻau, a me nā wahi nui o nā kumulāʻau ululāʻau i luku ʻia, ʻo nā kumulāʻau ʻohe ke koho maikaʻi loa. No laila, ma ke ʻano o ke kumukūʻai, ʻoi aku ka maikaʻi o ka papahele ʻohe ma mua o ka papahele lāʻau.

ʻOi aku ka olakino o ka papahele ʻohe ma mua o ka papahele lāʻau.

ʻO ka papahele ʻohe he mau mea mālama wela, he mahana i ka hoʻoilo a ʻoluʻolu i ke kauwela. ʻO ka hoʻohana ʻana i ka papahele ʻohe hiki ke hōʻemi i ka ulu ʻana o nā maʻi e like me ka rumatika, ka maʻi o ka naʻau, a me ka maʻi puʻuwai, pale i ka hānō maʻi, a hoʻopau i ka luhi, ma waena o nā hana ʻē aʻe. ʻO ka papahele ʻohe nō hoʻi ka leo absorption, ke kani ʻana o ke kani, a me ka hoʻohaʻahaʻa ʻana i ke kani ʻana o ke kani, e ʻoi aku ka mālie o ka nohona, a ʻoi aku ka maikaʻi o ke ola kino a me ka noʻonoʻo ma mua o nā huahana lāʻau.

ʻOi aku ka pale ʻana o ka papahele ʻohe ma mua o ka papahele lāʻau paʻa.

ʻO ke kūpaʻa ʻana o ka papahele ma muli o ka paʻakikī o kāna mea ʻili. ʻO ka papahele lāʻau paʻa a me ka papahele ʻohe he paʻi pena ma ko lākou ʻili, akā ʻoi aku ka paʻakikī o ka papahele ʻohe ma mua o ka papahele lāʻau paʻa. No laila, ma hope o ka lōʻihi o ka hoʻohana ʻana, ke pau ka pena o ka ʻili, ʻoi aku ka lōʻihi o ka papahele ʻohe ma mua o ka papahele lāʻau paʻa.

ʻOi aku ka pale o ka wai a me ka makū o ka papahele ʻohe ma mua o ka papahele lāʻau.

Aia kahi hoʻokolohua liʻiliʻi: e hoʻoinu i kahi ʻāpana papahele ʻohe a me kahi ʻāpana papa lāʻau paʻa i ka wai no 24 mau hola. E ʻike ʻoe i ka hoʻonui ʻana o ka papahele lāʻau paʻa i ʻelua o kona nui mua, ʻoiai ʻaʻohe loli o ka papahele ʻohe. No laila hiki i ka papahele ʻohe ke kū i ke kaomi ʻoi aku. He maikaʻi loa ka papahele ʻohe ʻo韧性 (ʻoʻoleʻa) a ʻoluʻolu loa ke hele.

ʻOi aku ka lōʻihi o ke ola o ka papahele ʻohe ma mua o ka papahele lāʻau.

ʻO ka papahele ʻohe ma kahi o 20 mau makahiki. ʻO ka hoʻohana kūpono a me ka mālama ʻana he kī nui ia e hoʻolōʻihi i ke ola o ka papahele ʻohe. He 8-10 mau makahiki ke ola o ka lāʻau composite.

ʻOi aku ka pale ʻana o ka papahele ʻohe ma mua o ka papahele lāʻau.

ʻO nā ʻāpana liʻiliʻi liʻiliʻi, ma hope o ka puhi ʻana a me ka carbonization kiʻekiʻe, ua hoʻopau loa ʻia nā meaʻai āpau i loko o ka ʻohe, no laila e hoʻopau ai i ka nohona ola no ka bacteria. Hana ʻia ka papahele lāʻau a hoʻomaloʻo ʻia i nā ʻāpana holoʻokoʻa, akā ʻaʻole pono ka mālama ʻana, no laila hiki ke maʻalahi i ka infestation insect.

ʻOi aku ka ikaika flexural o ka papahele ʻohe ma mua o ka papahele lāʻau.

Hiki ke piʻi ka ikaika flexural o ka papahele ʻohe i 1300 kg/cm³, ʻo ia ka 2-3 mau manawa o ka papahele lāʻau. ʻO ka hoʻonui a me ka hoʻololi ʻana o ka papahele lāʻau he pālua ia o ka papahele ʻohe. ʻO ka ʻohe ponoʻī kekahi elasticity, hiki ke hoʻohaʻahaʻa maikaʻi i ka ʻumekaumaha ma nā wāwae a hoʻopau i ka luhi i kekahi ʻano. Paʻa ka maikaʻi o ka papahele ʻohe. He mea hoʻonani kiʻekiʻe no nā hale noho, nā hōkele, a me nā keʻena.

ʻOi aku ka ʻoluʻolu o ka papahele ʻohe ma mua o ka papahele lāʻau.

Ma keʻano o kaʻoluʻolu, hiki ke'ōleloʻia he mahana i ka hoʻoilo a me ke anuanu i ke kauwela. ʻO kēia ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa o ka lāʻau a me ka ʻohe, e ʻae ana i ka poʻe e hele mālie me ke kamaʻa ʻole ma luna o lākou me ka nānā ʻole i ke kau.

He liʻiliʻi ka waihoʻoluʻu o ka papahele ʻohe ma mua o ka papahele lāʻau.

ʻO ke ʻano ʻohe kūlohelohe, hou, nani, a nani hoʻi ka waihoʻoluʻu, ʻo ia ka mea i makemake ʻia i ka papahele papahele no ka hana ʻana i kahi home pastoral hou, kūpono loa me ka makemake o ka poʻe e hoʻi i ke ʻano. ʻO ka leo kala he hou a nani, me nā puʻupuʻu ʻohe i hoʻopili ʻia, e hōʻike ana i kahi ʻano hanohano a me ka lewa moʻomeheu. ʻOi aku ka maikaʻi o ka waihoʻoluʻu ma mua o ka papahele lāʻau, e hana ana i kahi hopena hoʻonaninani kūlohelohe.

ʻOi aku ka paʻa o ka papahele ʻohe ma mua o ka papahele lāʻau.

ʻO ka ʻohe i loko papahele ʻohe he ʻano ʻano pōhaku lepo, hoʻonui nui i ka ikaika tensile a me ka ikaika compressive. ʻO ka papahele lāʻau kahi papahele i hana pololei ʻia mai ka lāʻau, a ʻo ia ke ʻano kuʻuna a kahiko loa.
