Pehea e hana ai i ka ʻōpala palaoa no ka hana pepa

I ka hana pepa hou, ʻo ka mea maka i hoʻohana nui ʻia he pepa ʻōpala a me ka pulp puʻupaʻa, akā i kekahi manawa ʻaʻole loaʻa ka pepa ʻōpala a me ka pulp puʻupaʻa ma kekahi mau wahi, paʻakikī ke loaʻa a pipiʻi paha ke kūʻai, i kēia hihia, hiki i ka mea hana ke noʻonoʻo e hoʻohana i ka ʻōpala palaoa ma ke ʻano he mea maka e hana ai i ka pepa, ʻo ka ʻōpala palaoa kahi huahana maʻamau o ka mahiʻai, he maʻalahi ke loaʻa, nui ka nui a emi ke kumukūʻai.

Ke hoʻohālikelike ʻia me ka olonā lāʻau, ʻoi aku ka palupalu a me ka palupalu o ka olonā mauʻu palaoa, ʻaʻole maʻalahi ke hoʻokeʻokeʻo i ke keʻokeʻo, no laila i ka hapa nui o nā hihia, hoʻohana pinepine ʻia ka mauʻu palaoa e hana i ka pepa fluting a i ʻole ka pepa corrugated, ua hui pū kekahi wili pepa i ka pulp mauʻu palaoa me ka pulp puʻupaʻa a i ʻole ka pepa ʻōpala e hana i ka pepa ʻiʻo haʻahaʻa a i ʻole ka pepa keʻena, akā ua manaʻo ʻia ka pepa fluting a i ʻole ka pepa corrugated ʻo ia ka huahana punahele loa, no ka mea he maʻalahi ke kaʻina hana a he emi ke kumukūʻai hana.

No ka hana ʻana i ka pepa, pono e ʻoki mua ʻia ka ʻōpala palaoa, makemake ʻia ka lōʻihi o 20-40mm, ʻoi aku ka maʻalahi o ka hoʻoili ʻana i ka ʻōpala a i ʻole ke kāwili ʻana me nā kemika kuke, noi ʻia kahi mīkini ʻoki ʻōpala palaoa e hana i ka hana, akā me ka loli o ka ʻoihana mahiʻai hou, ʻohi pinepine ʻia ka palaoa e nā mīkini, i kēia hihia, ʻaʻole manaʻo ʻia he pono ka mīkini ʻoki. Ma hope o ka ʻoki ʻana, e hoʻoili ʻia ka ʻōpala palaoa e hui pū me nā kemika kuke, hoʻohana pinepine ʻia ke kaʻina hana kuke soda caustic i kēia kaʻina hana, no ka palena ʻana i ke kumukūʻai kuke, hiki ke noʻonoʻo ʻia ka wai pōhaku lime. Ma hope o ka hui maikaʻi ʻana o ka ʻōpala palaoa me nā kemika kuke, e hoʻoili ʻia i kahi digester poepoe a i ʻole ka loko kuke ma lalo o ka honua, no ka kuke ʻana i ka mea maka liʻiliʻi, ʻōlelo ʻia ka loko kuke ma lalo o ka honua, kūkulu ʻana i ka hana kīwila, emi ke kumukūʻai, akā haʻahaʻa ka pono. No ka hiki ke hana kiʻekiʻe, pono e noʻonoʻo e hoʻohana i ka digester poepoe a i ʻole ka mea kuke pili, ʻo ka pono o ka kuke ʻana, akā ʻoiaʻiʻo, e kiʻekiʻe nō hoʻi ke kumukūʻai o nā lako. Hoʻopili ʻia ka loko kuke ma lalo o ka honua a i ʻole ka digester poepoe me ka mahu wela, me ka piʻi ʻana o ka mahana i loko o ka ipu a i ʻole ka pahu a me ka hui pū ʻana o ka mea kuke, ka lignin a me ke olonā e hoʻokaʻawale ʻia kekahi i kekahi. Ma hope o ke kaʻina kuke ʻana, e hoʻokuʻu ʻia ka ʻōpala palaoa mai ka ipu kuke a i ʻole ka pahu kuke i kahi pahu puhi a i ʻole ka pahu sediment e mākaukau e unuhi i ka fiber, ʻo ka mīkini maʻamau i hoʻohana ʻia he mīkini bleaching, ka mīkini holoi pulp wikiwiki kiʻekiʻe a i ʻole ka extruder bivis, a hiki i kēlā manawa e unuhi piha ʻia ka ʻōpala palaoa, ma hope o ke kaʻina hana o ka hoʻomaʻemaʻe ʻana a me ka kānana ʻana, e hoʻohana ʻia e hana i ka pepa. Ma waho aʻe o ka hana pepa, hiki ke hoʻohana ʻia ka ʻōpala palaoa no ka hoʻoheheʻe ʻana i ka pā lāʻau a i ʻole ka hoʻoheheʻe ʻana i ka pā hua manu.
