He aha ka pulp?

ʻO ka pulp he mea fibrous i loaʻa mai nā mea kanu me nā ʻano hana like ʻole.Hiki ke hoʻokaʻawale ʻia i loko o ka pulp mechanical, ka pulp kemika a me ka pulp mechanical kemika e like me ke ʻano hana;hiki ke hoʻokaʻawale ʻia i loko o ka pulp lāʻau, ka pulupulu mauʻu, ka pulp hemp, ka pulp ʻohe, ka pulp kō, ka pulp ʻohe, ka pulp rag a pēlā aku e like me ka fiber raw material i hoʻohana ʻia.Hiki ke hoʻokaʻawale ʻia i loko o ka pulp hoʻomaʻemaʻe, ka pulp bleached, ka pulp unbleached, ka pulp kiʻekiʻe, a me ka pulp semi-chemical e like me nā maʻemaʻe like ʻole.Hoʻohana maʻamau i ka hana ʻana i ka pepa a me ke kāleka.ʻAʻole hoʻohana wale ʻia ka pulp hoʻomaʻemaʻe no ka hana ʻana i ka pepa kūikawā, akā hoʻohana pinepine ʻia e like me ka mea maka no ka hana ʻana i nā derivatives cellulose e like me cellulose esters a me cellulose ethers.Hoʻohana pū ʻia i nā fibers i hana ʻia e ke kanaka, plastics, coatings, films, gunpowder a me nā māla ʻē aʻe.

ʻO ka pulping kuʻuna e pili ana i ke kaʻina hana o ka hoʻokaʻawale ʻana i nā mea kanu lāʻau i loko o ka pulp kūlohelohe a i ʻole ka bleached e nā ʻano kemika, nā ʻano mechanical a i ʻole ka hui pū ʻana o nā ʻano ʻelua.ʻO ke kaʻina hana maʻamau ʻo ia ka pulverizing, ka kuke ʻana, ka holoi ʻana, ka kānana, ka bleaching, ka hoʻomaʻemaʻe a me ka hoʻomaloʻo ʻana i nā mea kanu fiber maka.Ua hoʻomohala ʻia kahi ʻano pulping biological hou i kēia manawa.ʻO ka mua, hoʻohana ʻia nā bacteria kūikawā (keʻokeʻo keʻokeʻo, ka pala ʻeleʻele, ka pala palupalu) e hoʻoheheʻe pono i ke ʻano o ka lignin, a laila hoʻohana ʻia nā ʻano mechanical a i ʻole kemika e hoʻokaʻawale i ke koena cellulose., ukali ʻia e ka bleaching.Ma kēia kaʻina hana, ua decomposed nā mea ola a wehe i ka hapa nui o ka lignin, a hoʻohana ʻia ke ʻano kemika ma ke ʻano he hana kōkua.Ke hoʻohālikelike ʻia me ke ʻano kuʻuna, ʻoi aku ka liʻiliʻi o nā huahana kemika i hoʻohana ʻia, no laila hiki ke hoʻokuʻu ʻia ka liʻiliʻi a i ʻole ka wai ʻōpala.He ʻano hana pulping ʻoluʻolu., Keʻano pulping maʻemaʻe.
