●Kaʻina hana pepa pulp ʻohe
Mai ka holomua ʻana o ka ʻoihana a me ka hoʻohana ʻana i ka ʻohe, nui nā kaʻina hana hou, nā ʻenehana a me nā huahana no ka hana ʻohe i puka mai kekahi ma hope o kekahi, kahi i hoʻomaikaʻi nui ai i ka waiwai hoʻohana o ka ʻohe. ʻO ka hoʻomohala ʻana o ka ʻenehana pulping mechanized China ua haki ma o ke ʻano hana lima kuʻuna a ke hoʻololi nei i kahi ʻano hana ʻenehana a me ka hana ʻenehana. ʻO nā kaʻina hana hana pulp bamboo kaulana i kēia manawa he mechanical, chemical and chemical mechanical. ʻO ka pulupulu ʻohe o Kina ka nui o nā kemika, ʻo ia ka helu ma kahi o 70%; ʻoi aku ka liʻiliʻi o ka mechanical mechanical, emi ma mua o 30%; ʻo ka hoʻohana ʻana i nā ʻano hana mechanical e hana ai i ka pulp bamboo i kaupalena ʻia i ka pae hoʻokolohua, ʻaʻohe hōʻike ʻoihana nui.
1.Mechanical pulping ala
ʻO ke ʻano o ka pulping mechanical ʻo ka wili ʻana i ka ʻohe i loko o nā fiber e nā ʻano hana me ka hoʻohui ʻole i nā mea kemika. Loaʻa iā ia nā pōmaikaʻi o ka pollution haʻahaʻa, kiʻekiʻe pulping rate a me ka hana maʻalahi. Ma lalo o ke kūlana o ka hoʻomalu ʻana i ka pollution ikaika a me ka nele o nā kumuwaiwai pulp lāʻau i ka ʻāina, ua hoʻomaikaʻi ʻia ka pulp mechanical bamboo e nā kānaka.
ʻOiai ka maikaʻi o ka pulping mechanical i ka helu pulping kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, hoʻohana nui ʻia i ka pulping a me ka ʻoihana hana pepa o nā mea coniferous e like me ka spruce. Eia naʻe, ma muli o ke kiʻekiʻe o ka lignin, ka lehu, a me ka 1% NAOH extract i loko o ke kinikini o ka ʻohe, ʻilihune ka maikaʻi o ka pulp a paʻakikī ke hoʻokō i nā koi o ka pepa kalepa. He kakaikahi ka noi ʻenehana a aia ka hapa nui ma ke kahua o ka noiʻi ʻepekema a me ka ʻimi ʻenehana.
2.Chemical pulping ala
Hoʻohana ke ʻano pulping kemika i ka ʻohe ma ke ʻano he mea maka a hoʻohana i ke ʻano sulfate a i ʻole ke ʻano sulfite e hana ai i ka pulp ʻohe. Hoʻopili ʻia nā mea maka o ka ʻohe, holoi ʻia, hoʻomaʻemaʻe ʻia, kuke ʻia, causticized, kānana, holoi ʻia countercurrent, pani pani ʻia, deligification oxygen, bleaching a me nā hana ʻē aʻe e hana ai i ka pulp bamboo. Hiki i ke ʻano pulping kemika ke pale i ka fiber a hoʻomaikaʻi i ka helu pulping. ʻO ka pulp i loaʻa he maikaʻi maikaʻi, maʻemaʻe a palupalu, maʻalahi i ka bleach, a hiki ke hoʻohana ʻia e hana i ka pepa kākau kiʻekiʻe a me ka pepa paʻi.
Ma muli o ka lawe ʻia ʻana o ka nui o ka lignin, ka lehu a me nā ʻano ʻokoʻa like ʻole i ke kaʻina hana pulping o ke ʻano pulping kemika, ʻoi aku ka haʻahaʻa o ka pulping o ka pulping bamboo, maʻamau 45% ~ 55%.
3. Kemimi Mechanical Pulping
ʻO ka Pulping Mechanical Chemical kahi ʻano pulping e hoʻohana ana i ka ʻohe ma ke ʻano he mea maka a hoʻohui i kekahi mau hiʻohiʻona o ka pulping kemika a me ka pulping mechanical. ʻO ka Pulping Mechanical Chemical me ke ʻano semi-kemika, ke ʻano mechanical mechanical a me ke ʻano thermomechanical kemika.
No ka pulupulu ʻohe a me ka hana pepa, ʻoi aku ka kiʻekiʻe o ka pulping o ka pulping mechanical mechanical ma mua o ka pulping kemikal, hiki ke piʻi i ka 72% ~ 75%; ʻoi aku ka kiʻekiʻe o ka pulp i loaʻa i ka pulping mechanical ma mua o ka pulping mechanical, hiki ke hoʻokō i nā koi maʻamau o ka hana pepa huahana. I ka manawa like, ʻo ke kumukūʻai o ka hoʻihoʻi ʻana i ka alkali a me ka mālama ʻana i ka wai ma waena o ka pulping kemikal a me ka pulping mechanical.
▲Laina Hana Hana Pulping Bamboo
● Lako Hana Pepa Pulp Bamboo
ʻO nā mea hana o ka ʻāpana hana o ka laina hana hana pepa pulp bamboo he mea like ia me ka laina hana pulp lāʻau. ʻO ka ʻokoʻa nui loa o nā mea hana pepa pulp ʻohe aia ma nā ʻāpana hoʻomākaukau e like me ka ʻoki ʻana, ka holoi ʻana a me ka kuke ʻana.
No ka mea, ʻo ka ʻohe, he ʻokoʻa nā mea ʻoki ʻoki me ko ka lāʻau. ʻO nā mea hana maʻamau i hoʻohana ʻia i ka ʻoki ʻohe, ka mea ʻoki ʻohe disc a me ka ʻoki pahu. He kiʻekiʻe ka maikaʻi o ka hana ʻana i nā mea ʻoki ʻohe Roller a me nā ʻoki ʻohe diski, akā ʻaʻole maikaʻi ka maikaʻi o nā ʻōpala ʻohe i hoʻoponopono ʻia (ke ʻano ʻohe ʻohe) e like me ka maikaʻi o nā ʻōpala pahu. Hiki i nā mea hoʻohana ke koho i nā mea hana ʻoki (fllaking) kūpono e like me ke kumu o ka pulp bamboo a me ke kumukūʻai hana. No nā mea kanu ʻohe liʻiliʻi a me ka liʻiliʻi liʻiliʻi (puka <100,000 t/a), lawa nā lako ʻoki ʻohe i ka home no ka hoʻokō ʻana i nā pono hana; no nā mea kanu pulu ʻohe nui (hua hoʻopuka ≥100,000 t/a), hiki ke koho ʻia nā mea hana ʻoki nui (fllaking) kiʻekiʻe o ka honua.
Hoʻohana ʻia nā mea holoi ʻohe e wehe i nā haumia, a ua hōʻike ʻia nā huahana patented he nui ma Kina. ʻO ka mea maʻamau, hoʻohana ʻia nā mea holoi pulp vacuum, nā mea holoi pulupulu kaomi a me nā mea holoi pulp kāʻei. Hiki i nā ʻoihana liʻiliʻi a me nā ʻoihana nui ke hoʻohana i nā mea holoi pulupulu paʻi pālua-roller hou a i ʻole nā mea holoi pulu wai ikaika.
Hoʻohana ʻia nā mea kuke kīʻaha ʻohe no ka hoʻomaʻemaʻe ʻana i ka ʻohe a me ka hoʻokaʻawale kemika. Hoʻohana nā ʻoihana liʻiliʻi a liʻiliʻi i nā ipu kuke kūpaʻa a i ʻole nā mea kuke hoʻomau mau. Hiki i nā ʻoihana nui ke hoʻohana i nā mea kuke hoʻomau ʻo Camille me ka holoi diffusion e hoʻomaikaʻi i ka hana hana, a e hoʻonui ʻia ka hua pulp e like me ia, akā e hoʻonui i ke kumukūʻai hoʻokahi manawa.
ʻO 1.Bamboo pulp papermaking he mana nui
Ma muli o ka noiʻi ʻana i nā kumu waiwai ʻohe o Kina a me ka nānā ʻana i ke kūpono o ka ʻohe ponoʻī no ka hana pepa, ʻo ka hoʻomohala ikaika ʻana i ka ʻoihana pulping ʻohe ʻaʻole hiki ke hoʻopau wale i ka pilikia o nā kumu lāʻau paʻa i ka ʻoihana pepa o Kina, akā he ala maikaʻi hoʻi e hoʻololi ai. ʻO ke ʻano kumu waiwai o ka ʻoihana hana pepa a hoʻemi i ka hilinaʻi ʻana i nā ʻāpana lāʻau i lawe ʻia mai. Ua ʻimi kekahi poʻe naʻauao he 30% ka haʻahaʻa o ke kumukūʻai o ka pulp bamboo no kēlā me kēia ʻāpana ma mua o ka pine, spruce, eucalyptus, etc.
2. ʻO ka hoʻohui ʻana o ka nahele-pepa he kuhikuhi hoʻomohala koʻikoʻi
Ma muli o ka wikiwiki o ka ulu a me ka hoʻoponopono hou ʻana o ka ʻohe, e hoʻoikaika i ka mahi ʻana i nā ululāʻau ʻohe kūikawā e ulu wikiwiki ana a me ka hoʻokumu ʻana i kahi kumu hana pulp bamboo e hoʻohui i ka nahele a me ka pepa e lilo i alakaʻi no ka hoʻomohala mau ʻana o ka pulp a me ka ʻoihana hana pepa o Kina, e hōʻemi ana. ka hilinaʻi ʻana i nā ʻāpana lāʻau a me ka pulp, a me ka hoʻomohala ʻana i nā ʻoihana aupuni.
ʻO 3.Cluster bamboo pulping he mea hiki ke hoʻomohala nui
I ka ʻoihana hana ʻohe o kēia manawa, ʻoi aku ma mua o 90% o nā mea maka i hana ʻia me ka moso bamboo (Phoebe nanmu), i hoʻohana nui ʻia e hana i nā mea hale a me nā mea hana. Hoʻohana nui ka ʻohe pulp papermaking i ka moso bamboo (Phoebe nanmu) a me ka cycad bamboo ma ke ʻano he kumu waiwai, e hana ana i kahi kūlana hoʻokūkū maka a ʻaʻole kūpono i ka hoʻomohala mau o ka ʻoihana. Ma ke kumu o nā ʻano ʻohe maka i kēia manawa, pono e hoʻomohala ikaika ka ʻoihana pulp pulp papermaking i nā ʻano ʻano ʻohe no ka hoʻohana ʻana i nā mea maka, e hoʻohana piha i ka ʻohe cycad kumu kūʻai haʻahaʻa, ʻohe deragona nunui, ʻohe huelo phoenix, dendrocalamus latiflorus a me nā ʻohe ʻē aʻe no ka pulping a me ka hana pepa, a hoʻomaikaʻi i ka hoʻokūkū mākeke.
