ʻO ka hopena o ka fiber morphology i nā waiwai pulp a me ka maikaʻi

I ka ʻoihana pepa, ʻo ka fiber morphology kekahi o nā kumu nui e hoʻoholo ai i nā waiwai pulp a me ka maikaʻi o ka pepa hope. Hoʻopili ʻia ka morphology fiber i ka lōʻihi awelika o nā fiber, ka lakio o ka mānoanoa o ka paia o ka fiber cell i ke anawaena o ke kelepona (i kapa ʻia ʻo ka ratio wall-to-cavity), a me ka nui o nā heterocytes non-fibrous a me nā pūpū fiber i loko o ka pulp. Hoʻopili kēia mau mea i kekahi i kekahi, a pili pū i ka ikaika paʻa o ka pulp, ka maikaʻi dehydration, ka hana kope ʻana, a me ka ikaika, ka paʻakikī a me ka maikaʻi o ka pepa.

1) Ka lōʻihi o ka fiber
ʻO ka lōʻihi maʻamau o nā fiber kekahi o nā hōʻailona koʻikoʻi o ka maikaʻi o ka pulp. Hoʻokumu nā fiber lōʻihi i nā kaulahao pūnaewele lōʻihi i loko o ka pulp, e kōkua ana i ka hoʻoikaika ʻana i ka ikaika paʻa a me nā waiwai tensile o ka pepa. Ke piʻi aʻe ka lōʻihi o ka lōʻihi o nā fiber, piʻi ka helu o nā kiko i ulana ʻia ma waena o nā fibers, e ʻae ana i ka pepa e hoʻopuehu maikaʻi i ke koʻikoʻi ke hoʻokau ʻia i nā mana o waho, pēlā e hoʻomaikaʻi ai i ka ikaika a me ka paʻakikī o ka pepa. No laila, ʻo ka hoʻohana ʻana i nā fiber lōʻihi lōʻihi, e like me ka spruce coniferous pulp a i ʻole ka pulupulu a me ka pulp olonā, hiki ke hana i ka ikaika kiʻekiʻe, ʻoi aku ka paʻakikī o ka pepa, ʻoi aku ka maikaʻi o kēia mau pepa no ka hoʻohana ʻana i ka pono o nā waiwai kino kiʻekiʻe o ka manawa. e like me nā mea hoʻopili, paʻi pepa a pēlā aku.
2) ʻO ka lakio o ka mānoanoa o ka paia o ka fiber cell i ke anawaena o ka lua (wall-to-cavity ratio)
ʻO ka lākiō pā-a-cavity kekahi mea nui e pili ana i nā waiwai pulp. ʻO ka lākiō haʻahaʻa pā-i-cavity, ʻo ia hoʻi, ʻoi aku ka lahilahi o ka pā fiber cell a ʻoi aku ka nui o ka cell cavity, no laila ʻoi aku ka maʻalahi o nā pulupulu i ka pulping a me ka hana pepa e hoʻomoʻa i ka wai a palupalu, kūpono i ka hoʻomaʻemaʻe ʻana i nā fibers, dispersion. a hui pū. I ka manawa like, ʻoi aku ka maikaʻi o ka hoʻololi ʻana a me ka foldable i ka wā e hana ai i ka pepa, i kūpono i ka pepa no ka hana paʻakikī a me ka hana ʻana. ʻO ka ʻokoʻa, hiki i nā fibers me ka pā kiʻekiʻe o ka pā-a-cavity ratio hiki ke alakaʻi i ka pepa paʻakikī nui, ʻaʻole kūpono i ka hana a me ka hoʻohana ʻana.
3) Maʻiʻo o nā heterocytes non-fibrous a me nā pūpū fiber
ʻO nā pūnaewele non-fibrous a me nā pūpū fiber i loko o ka pulp he mau kumu maikaʻi ʻole e pili ana i ka maikaʻi o ka pepa. ʻAʻole e hōʻemi wale kēia mau mea haumia i ka maʻemaʻe a me ka like ʻole o ka pulp, akā i loko o ke kaʻina hana pepa e hana ai i nā knots a me nā hemahema, e pili ana i ka maʻalahi a me ka ikaika o ka pepa. Hiki i nā heterocytes non-fibrous ke kumu mai nā ʻāpana non-fibrous e like me ka ʻili, ka resin a me nā ʻāʻī i loko o ka mea maka, ʻoiai ʻo nā pūpū fiber he mau fiber aggregates i hoʻokumu ʻia ma muli o ka hiki ʻole o ka mea maka ke wehe pono i ka wā o ka hoʻomākaukau ʻana. No laila, pono e hoʻoneʻe ʻia kēia mau mea haumia e like me ka hiki i ka wā o ka pulping e hoʻomaikaʻi i ka maikaʻi o ka pulp a me ka hua pepa.
