ʻO ka pilina ma waena o ka maikaʻi o ka fiber a me nā waiwai fiberboard

 

 

(1) Ka pilina ma waena o ka fiber morphology a me ka maikaʻi o ka huahana

 

E pili ana i ke ʻano maoli o ka fiber, nui nā ʻokoʻa ma waena o nā mea maka.No ka laʻana, ʻo ka awelika o ka lōʻihi o nā tracheids fiber o ka lāʻau coniferous he 2-3 mm, a ʻo ka lākiō hiʻohiʻona he 63-110;ʻO ka awelika o ka lōʻihi o ka fiber tracheids a me ka lāʻau paʻakikī o ka lāʻau ākea ākea he 0.8-1.3 mm, a ʻo ka lākiō hiʻohiʻona he 35-110 58;e like me ka mauʻu fiber maka mea, ka awelika lōʻihi o ka fiber tracheids wale 0.8-2.2 mm, ka hiʻona lākiō o 30-130, a me ka maʻiʻo o ka non-fiber pūnaewele mea kiʻekiʻe.

 

Mai ka hiʻohiʻona o ka lōʻihi o ka fiber a me ka ratio hiʻohiʻona, ʻoi aku ka maikaʻi o ka fiberboard i hana ʻia me nā fiberwood softwood.Eia naʻe, ua hōʻike ʻia ʻo ka hana o ka fiberboard i kaomi ʻia e nā mea coniferous a pau ʻaʻole pono ka maikaʻi.ʻO kēia no ka mea he tubular ka mānoanoa o nā tracheids fiber o nā mea coniferous, a ʻoi aku ka nui o ka mānoanoa o ka paia cell ma mua o ka laulā o nā fibers.ʻOi aku ka liʻiliʻi o ka huina pili.ʻO ka mea ʻē aʻe, ʻo nā tracheids fiber, nā wili lāʻau paʻakikī, a me nā ʻaukā o ka lāʻau lau ākea, he paia lahilahi a me ke ʻano o ke ʻano, no laila ua nui ka wahi hoʻopili ma waena o nā fiber, a maikaʻi ka waiwai interweaving.ʻO ka huahana fiberboard me ke kiʻekiʻe kiʻekiʻe a me ka ikaika.

 

ʻO ka ikaika maoli o ka fiber pono'ī kekahi mana i ka ikaika o ka huahana fiberboard.Ua hoʻohana kekahi i ke ʻano hoʻoluʻu no ka hoʻāʻo ʻana i nā hoʻāʻo ʻana a me ka tensile hemahema o ka fiberboard paʻakikī, a nānā ʻia ma lalo o ka microscope, ua ʻike ʻia he 60% a 70% o nā fibers hoʻokahi i pōʻino.Mai ka hopena o ka hoʻāʻo ʻana, ua manaʻo ʻia ʻo ka ikaika o ka monomer fiber ponoʻī ʻaʻohe hopena i ka ikaika o ka fiberboard palupalu me ka nui o 0.25-0.4g/cm3.Loaʻa iā ia kahi hopena ʻoi aku ka ʻike ma ka ikaika o ka fiberboard density me ka nui o 0.4-0.8g/cm3.E loaʻa iā ia ka hopena nui aʻe i ka ikaika o nā fiberboards kiʻekiʻe me ka nui o ka nui ma mua o 0.9g/cm3.ʻO kēia no ka mea, pili ka ikaika maoli o ka fiber hoʻokahi i ka lōʻihi o ke kaula cellulose (ʻo ia hoʻi, ke degere o ka polymerization), a hiki i ka haʻihaʻi ʻana o ka fiber hoʻokahi ke hiki i 40000Pm.Ma hope o ka paʻi ʻia ʻana o nā fibers a hoʻokumu ʻia i mau papa, aia ka hoʻonohonoho ʻokoʻa i ke ʻano o ka hoʻopuehu ʻia a me ka ʻole.Ma hope o ka hoʻopau ʻana i ka mana o nā kumu ʻē aʻe, me ka manaʻo ʻana ʻo ka awelika haʻihaʻi lōʻihi o ka fiber hoʻokahi he 20 000 Pm, a laila helu ʻia e like me ka helu conservative o 40%, ka fiber hoʻokahi Hiki i ka lōʻihi o ka haki ke hiki i 8 000 Pm.Hiki ke ʻike ʻia ka pilina ma waena o ka ikaika maoli o ka fiber ponoʻī a me ka ikaika o ka huahana fiberboard.

 

(2) ʻO ka pilina ma waena o ke degere o ka hoʻokaʻawale ʻana i ka fiber a me ka maikaʻi o ka fiberboard

 

ʻO ke kiʻekiʻe o ka hoʻokaʻawale ʻana o ka fiber e pili ana i ke kiʻekiʻe o ka hoʻokaʻawale ʻana o ka fiber ma hope o ka defibration, ʻo ia kahi hiʻohiʻona e hōʻike pololei ʻole i ka maikaʻi o nā fiber.ʻO ka ʻoi aku ka maikaʻi o ka hoʻokaʻawale ʻana i ka fiber, ʻoi aku ka nui o ka ʻāpana kikoʻī o ka fiber, a ʻoi aku ka ʻilihune o ka hoʻokahe wai a me ka permeability o ka ea.ʻO ka ʻoi aku ka maikaʻi o ka kānana wai a me ka hikiwawe o ka ea o ka fiber, akā ʻoi aku ka mānoanoa o ka fiber i kēia manawa a ʻoi aku ka liʻiliʻi o ka ʻili kiko o ka fiber.Ma hope o ka hoʻokaʻawale ʻana i ka fiber, ʻokoʻa ka ʻāpana ili o ka fiber i ka hoʻokahe wai.ʻOi aku ka nui o ka ʻili o ka ʻili, ʻoi aku ka maikaʻi o nā fiber, a ʻoi aku ka ʻino o ka hoʻokahe wai o ka fiber.Poor puluniu kaawale degere Coarse puluniu (28 ~ 48 mesh) he uuku ea kū'ē, oiai kiʻekiʻe puluniu kaawale degere a me ka maikai puluniu i nui kiko'ī ili āpana (100 ~ 200 mesh), ilihune ea permeability o ka pulupulu, maikaʻi slab hoʻopiha, akā nui ea. kūʻē.ʻO ka ʻoi aku ka nui o ka ʻili kiko o ka fiber, ʻoi aku ka liʻiliʻi o ka leo o ka fiber, a me ka hope.No laila hiki ke hoʻoholo i ka kānana, ka ea permeability a me ka leo o ka fiber a pau i kekahi pilina me ke degere o ka hoʻokaʻawale ʻana o ka fiber.No laila, hiki ke ʻōlelo ʻia he hōʻailona koʻikoʻi ka degere o ka hoʻokaʻawale ʻana i ka fiber no ka maikaʻi o ka fiber pulp, e pili pono ana i ke kaʻina hana fiber a me ka maikaʻi o ka huahana.Ua hōʻike pū ʻia ka hoʻomaʻamaʻa ʻana i loko o kekahi ʻano, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka hoʻokaʻawale ʻana i ka fiber, ʻo ia hoʻi, ʻoi aku ka maikaʻi o nā fibers, ʻoi aku ka maikaʻi o ka hoʻopili ʻana ma waena o nā fibers o ka papa, a me ka ikaika, ka wai a me ka nui o ka huahana o ka fiberboard. mahuahua no hoi.

 

Eia kekahi, ua hoʻoholo ʻia mai ka ʻike hana pono e hoʻomalu ʻia ka degere o ka hoʻokaʻawale ʻana i ka fiber i loko o kahi kikoʻī ma ke kumu o ka hoʻopaʻa ʻana i ka maikaʻi o ka huahana e like me nā ʻano huahana like ʻole a me nā ʻano hana.

 

(3) Ka pilina ma waena o ka waiwai kānana fiber a me ka maikaʻi o ka fiberboard

 

ʻO ke ʻano o ka fiber, ka lōʻihi o ka fiber, a me ka lākiō mānoanoa o ka fiber o nā ʻano like ʻole o ka fiber raw material e loaʻa i nā pae like ʻole o ka hopena i ka maikaʻi o ka fiberboard.ʻO ke ʻano o ka hoʻāʻo ʻana i ka maikaʻi o ka fiber ʻo ia ka hoʻohana ʻana i ka hoʻokaʻawale fiber (fiber freeness DS a me ka fiber percussion degree SR).No ka mea he ʻokoʻa loa ka fiber ponoʻī, paʻakikī pinepine ka noʻonoʻo ʻana i ke ʻano o ka maikaʻi o ka fiber ma ke ana ʻana i ke degere o ka hoʻokaʻawale ʻana o nā fiber wale nō.I kekahi manawa, ua like ka waiwai kūʻokoʻa o nā fiber ʻelua, akā ʻokoʻa ka lōʻihi a me ka mānoanoa o nā fiber.No laila, ua hoʻonui ʻia e ka hoʻāʻo ʻana i ka waiwai sieving fiber e nānā i ka maikaʻi o ka fiber i hoʻokaʻawale ʻia.

 

He mea koʻikoʻi ka waiwai kānana fiber i ka hana maoli.Hiki ke hoʻomaikaʻi i ke ʻano o ka fiber a me nā waiwai slurry i ka hoʻoponopono ʻana i ka waiwai o ka fiber slurry, a laila e hoʻomaikaʻi ai i ka maikaʻi o nā huahana fiberboard.ʻO ka noiʻi e pili ana i ka hopena o ka waiwai screening fiber i ka maikaʻi o ka fiberboard ua lōʻihi ka nānā ʻana, a ua loaʻa ke kumu ʻenehana maʻamau.Hoʻopili nui ʻia ka fiber morphology e ke ʻano mea a me ke ʻano o ka hoʻokaʻawale ʻana i ka fiber.ʻOi aku ka maikaʻi o ka lāʻau coniferous ma mua o ka lāʻau lau ākea.ʻOi aku ka maikaʻi o ke kaʻina hana kemika ma mua o ke ʻano mīkini hoʻomehana (ʻo ia hoʻi, ke ʻano wili wela), a ʻoi aku ka maikaʻi o ke ʻano mīkini maʻemaʻe.ʻilihune.
