I ka hana pepa hou, ʻo ka mea i hoʻohana nui ʻia he pepa ʻōpala a me ka pulp puʻupaʻa, akā i kekahi manawa ʻaʻole i loaʻa ka pepa ʻōpala a me ka pulp puʻupaʻa i kekahi wahi, paʻakikī ke kiʻi a i ʻole ke kumu kūʻai aku, ma kēia hihia, hiki i ka mea hana ke noʻonoʻo e e hoʻohana i ka mauʻu palaoa ma ke ʻano he mea maka no ka hana ʻana i ka pepa, ʻo ka mauʻu palaoa ka mea maʻamau o ka mahiʻai, maʻalahi ke loaʻa, nui ka nui a emi ke kumu kūʻai.
Ke hoʻohālikelike ʻia me ka fiber lāʻau, ʻoi aku ka maʻalahi o ka ʻōpala palaoa a nāwaliwali, ʻaʻole maʻalahi ke hoʻomaʻemaʻe keʻokeʻo, no laila, ma ka hapanui o nā hihia, ʻoi aku ka maʻamau o ka mauʻu palaoa e hana i ka pepa fluting a i ʻole ka pepa corrugated, kekahi wili pepa i hui pū ʻia me ka ʻōpala palaoa. ʻO ka pulp puʻupaʻa a i ʻole ka pepa ʻōpala no ka hana ʻana i ka pepa kiko haʻahaʻa haʻahaʻa a i ʻole ka pepa keʻena, akā ʻo ka pepa fluting a i ʻole ka pepa corrugated i manaʻo ʻia ʻo ia ka huahana punahele loa, no ka mea, maʻalahi ke kaʻina hana. emi mai.
No ka hana ʻana i ka pepa, pono e ʻoki mua ʻia ka mauʻu palaoa, ʻoi aku ka lōʻihi o 20-40mm, ʻoi aku ka maʻalahi o ka hoʻololi ʻana i ka mauʻu a hui pū ʻia me nā kemika kuke, noi ʻia kahi mīkini ʻoki mauʻu palaoa e hana i ka hana, akā me ka hoʻololi ʻana. ʻoihana mahiʻai hou, ʻohi pinepine ʻia ka palaoa e nā mīkini, i kēia hihia, ʻaʻole pono ka mīkini ʻoki. Ma hope o ka ʻoki ʻana, e hoʻoneʻe ʻia ka mauʻu palaoa e hui pū me nā kemika kuke, hoʻohana mau ʻia ke kaʻina hana kuke ʻana i ka soda caustic i kēia kaʻina hana, e kaupalena i ke kumukūʻai kuke, hiki ke noʻonoʻo ʻia ka wai pōhaku lime. Ma hope o ka hui maikaʻi ʻia ʻana o ka mauʻu palaoa me nā kemika kuke, e hoʻoneʻe ʻia ia i kahi digester spherical a i ʻole ka ʻauʻau kuke ʻana ma lalo o ka honua, no ka liʻiliʻi o ka ʻai meaʻai, ʻoi aku ka maikaʻi o ka ʻauʻau kai lalo, ke kūkulu ʻia ʻana o ka hana kīwila, emi ke kumu kūʻai, akā haʻahaʻa ka maikaʻi. No ka hana kiʻekiʻe, pono e noʻonoʻo e hoʻohana i ka spherical digester a i ʻole nā mea kuke ʻai contiguous, ʻoi aku ka maikaʻi o ka kuke ʻana, akā ʻoiaʻiʻo, ʻoi aku ka kiʻekiʻe o ke kumukūʻai. Hoʻopili ʻia ka loko ʻauʻau ma lalo o ka honua a i ʻole ka digester spherical me ka mahu wela, me ka piʻi ʻana o ka mahana i loko o ka moku a i ʻole ka pahu a me ka hui pū ʻana o ka mea kuke, e hoʻokaʻawale ʻia ka lignin a me ka fiber me kekahi. Ma hope o ke kaʻina kuke ʻana, e hoʻokuʻu ʻia ka mauʻu palaoa mai ka moku kuke a i ʻole ka pahu kuke i kahi pahu puhi a i ʻole ka pahu sediment mākaukau e unuhi i ka fiber, ʻo ka mīkini maʻamau ka mīkini bleaching, ka mīkini holoi pulp wikiwiki kiʻekiʻe a i ʻole bivis extruder, a laila ka mauʻu palaoa. e unuhi piha ʻia ka fiber, ma hope o ka hoʻomaʻemaʻe ʻana a me ka nānā ʻana, e hoʻohana ʻia ia 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 ʻia ʻana o ka pā hua manu.
