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 ke kūʻai aku, i kēia hihia, hiki i ka mea hana ke noʻonoʻo e hoʻohana i ka mauʻu palaoa i mea maka no ka hana ʻana i ka pepa, ʻo ka mauʻu palaoa he mea maʻamau o ka mahiʻai, maʻalahi ke kiʻi a emi ke kumu kūʻai.
Ke hoʻohālikelike ʻia me ka fiber lāʻau, ʻoi aku ka palupalu a nāwaliwali o ka ʻōpala palaoa, ʻaʻole maʻalahi ke hoʻomaʻemaʻe keʻokeʻo, no laila i 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, ʻo kekahi mea wili pepa i hui pū ʻia me ka pulp puʻupaʻa a i ʻole ka pepa ʻōpala e hana i ka pepa kiko haʻahaʻa a i ʻole pepa keʻena, akā ʻo ka pepa fluting a i ʻole ka pepa keʻena e manaʻo ʻia ke kumu kūʻai maʻalahi. 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 mauʻu e hoʻoneʻe ʻia a hui pū ʻia me nā kemika kuke, noi ʻia ka mīkini ʻoki ʻoki palaoa e hana i ka hana, akā me ka hoʻololi ʻana o ka ʻoihana mahiʻai hou, ʻohi 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 kiʻekiʻe a i ʻole bivis extruder, a laila e unuhi piha ʻia ka ʻōpala palaoa, ma hope o ke kaʻina hana o ka hoʻomaʻemaʻe a me ka nānā ʻana, e hoʻohana ʻia e hana 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.
