Nā Mea Maʻamau maʻamau i ka hana pepa: He alakaʻi piha

ʻO ka hana pepa he ʻoihana hoʻohanohano manawa e hilinaʻi nei i nā ʻano mea maka e hana i nā huahana pepa a mākou e hoʻohana ai i kēlā me kēia lā. Mai ka lāʻau a i ka pepa hana hou ʻia, loaʻa i kēlā me kēia mea nā hiʻohiʻona kūʻokoʻa e pili ana i ka maikaʻi a me ka hana o ka pepa hope. Ma kēia alakaʻi, e ʻimi mākou i nā mea maka maʻamau i ka hana pepa, ko lākou waiwai fiber, nā hua pulp, a me nā noi.

ʻO Wood: The Traditional Staple

ʻO ka lāʻau kekahi o nā mea maka i hoʻohana nui ʻia i ka hana pepa, me ʻelua mau ʻāpana: ka lāʻau palupalu a me ka lāʻau paʻa.

Laau palupalu

• Ka lōʻihi o ka fiber: Mai ka 2.5 a hiki i ka 4.5 mm.
• Hua'ai Pulp: Ma waena o 45% a me 55%.
• Nā hiʻohiʻona: He lōʻihi a hiki ke maʻalahi nā fiberwood no ka hana ʻana i ka pepa ikaika loa. ʻO ko lākou hiki ke hana i nā interlocks ikaika ka hopena i ka pepa me ka paʻa maikaʻi a me ka ikaika tensile. Hoʻolilo kēia i ka lāʻau palupalu i mea waiwai maka no ka hana ʻana i ka pepa kākau, paʻi pepa, a me nā mea hoʻopihapiha ikaika kiʻekiʻe.

Laau paʻa

• Ka lōʻihi o ka fiber: Ma kahi o 1.0 a 1.7 mm.
• Hua'ai Pulp: Maʻa mau 40% a 50%.
• Nā hiʻohiʻona: He pōkole ka lāʻau paʻa i ka lāʻau palupalu. ʻOiai lākou e hana i ka pepa me ka ikaika haʻahaʻa haʻahaʻa, ua hui pinepine ʻia lākou me ka pulp lāʻau palupalu e hana i ka pepa paʻi haʻahaʻa a me ka pepa kiko.

Nā mea mahiʻai a me nā mea kanu

Ma waho aʻe o ka lāʻau, waiwai nui nā huahana a me nā mea kanu i ka hana pepa, e hāʻawi ana i ka hoʻomau a me ka maikaʻi o ke kumukūʻai.

Mauʻu a me ka Palaoa

• Ka lōʻihi o ka fiber: Ma kahi o 1.0 a 2.0 mm.
• Hua'ai Pulp: 30% a 40%.
• Nā hiʻohiʻona: Loaʻa kēia mau mea i loaʻa a me nā kumu kūʻai kūpono. ʻOiai ʻaʻole kiʻekiʻe loa kā lākou hua pulp, kūpono lākou no ka hana ʻana i ka pepa moʻomeheu a me ka pepa pepa.

ʻOhe

• Ka lōʻihi o ka fiber: Mai ka 1.5 a 3.5 mm.
• Hua'ai Pulp: 40% a 50%.
• Nā hiʻohiʻona: He mau waiwai ko ka laau ohe me ka ikaika maikai. ʻO ka mea hou aku, he pōkole ka ulu ʻana o ka ʻohe a me ka hoʻololi hou ʻana, e lilo ia i mea koʻikoʻi i ka lāʻau. Hiki ke hoʻohana ʻia no ka hana ʻana i nā pepa like ʻole, me ka pepa moʻomeheu a me ka pepa paʻi.

Bagasese

• Ka lōʻihi o ka fiber: 0.5 a 2.0 mm.
• Hua'ai Pulp: 35% a 55%.
• Nā hiʻohiʻona: Ma ke ʻano he ʻōpala mahiʻai, waiwai nui ka bagasse i nā kumuwaiwai. He ʻokoʻa ka lōʻihi o kona fiber, akā ma hope o ka hana ʻana, hiki ke hoʻohana ʻia e hana i ka pepa paʻi a me ka pepa kiko.

Pepa ʻōpala: He koho mau

He kuleana koʻikoʻi ka pepa ʻōpala i ka hoʻokele waiwai o ka ʻoihana hana pepa.

• Ka lōʻihi o ka fiber: 0.7 mm a 2.5 mm. No ka laʻana, pōkole nā fibers i loko o ka pepa ʻōpala keʻena, ma kahi o 1 mm, ʻoiai ʻoi aku ka lōʻihi o nā mea i loko o kekahi pepa ʻōpala.
• Hua'ai Pulp: Nā ʻano like ʻole ma muli o ke ʻano, ka maikaʻi, a me ka ʻenehana hana o ka pepa ʻōpala, maʻamau mai 60% a 85%. Hiki ke loaʻa i nā ipu hao kahiko (OCC) ka hua pulp ma kahi o 75% a 85% ma hope o ka mālama pono ʻana, ʻoiai ʻo ka pepa ʻōpala o ke keʻena i hui pū ʻia he 60% a 70%.
• Nā hiʻohiʻona: ʻO ka hoʻohana ʻana i ka pepa ʻōpala ma ke ʻano he mea maka he mea ʻoluʻolu ke kaiapuni a he kiʻekiʻe ka hua pulp. Hoʻohana nui ʻia ia i ka hana ʻana i ka pepa recycled a me ka pepa corrugated, e hāʻawi ana i ka mālama waiwai a me ka hōʻemi ʻana i ka ʻōpala.

Nā memo hoʻoponopono kī

He mea nui e hoʻomaopopo he ʻokoʻa nā kaʻina hana pulping no nā mea maka.Pono e kuke ka lāʻau, ka ʻohe, ka mauʻu, a me ka ʻōpala palaoai ka pulping. Ke hoʻohana nei kēia kaʻina hana i nā kemika a i ʻole ka wela kiʻekiʻe a me ke kaomi e wehe i nā ʻāpana non-fibrous e like me ka lignin a me ka hemicellulose, e hōʻoia ana ua hoʻokaʻawale ʻia nā fibers a mākaukau no ka hana pepa.

ʻO ka ʻokoʻa, ʻaʻole pono ke kuke ʻana i ka pulping pepa ʻōpala. Akā, pili ia i nā kaʻina hana e like me ka deinking a me ka screening e wehe i nā haumia a hoʻomākaukau i nā fibers no ka hoʻohana hou ʻana.

He mea nui ka hoʻomaopopo ʻana i nā waiwai o kēia mau mea maka no nā mea hana pepa e koho i nā mea kūpono no kā lākou huahana kikoʻī, ke kaulike ʻana i ka maikaʻi, ke kumukūʻai, a me ka hoʻomau. Inā ʻo ka ikaika o nā fiberwood a i ʻole ka ʻoluʻolu o ka pepa ʻōpala, hāʻawi kūʻokoʻa kēlā me kēia mea maka i ka honua like ʻole o nā huahana pepa.
