ʻO ka hoʻoponopono ʻana i ka cellulose e pili ana i nā ʻano hana like ʻole e unuhi a hoʻomaʻemaʻe iā ia mai kona kumu kūlohelohe, ʻo ia hoʻi nā mea kanu. ʻO ka cellulose, he polysaccharide, ka mea i hoʻokumu ʻia i ka ʻāpana o nā paia cell i nā mea kanu a ʻo ia ka polymer organik nui loa ma ka Honua. He mea koʻikoʻi kāna hana ʻana i nā ʻoihana mai ka pepa a me ka textile i ka meaʻai a me nā lāʻau lapaʻau.
1. Ke kiʻi ʻana i nā lako maka:
Hoʻokumu mua ʻia ka cellulose mai nā mea kanu, me ka lāʻau a me ka pulupulu ke kumu maʻamau. ʻO nā kumu ʻē aʻe he hemp, flax, jute, a me kekahi mau algae. Loaʻa i nā mea kanu ʻokoʻa nā ʻano cellulose e pili ana i ka pono o ka unuhi a me ka hana ʻana.
2. Hana mua:
Ma mua o ka lawe ʻana i ka cellulose, hoʻomaʻamaʻa mua ʻia nā mea maka e wehe i nā mea cellulosic ʻole e like me ka lignin, hemicellulose, a me ka pectin. Hoʻonui kēia ʻanuʻu i ka pono o ka lawe ʻana i ka cellulose. ʻO nā ʻano hana hoʻomaʻamaʻa mua e pili ana i ka wili mīkini, ka mālama kemika (e laʻa, ka waikawa a i ʻole ka alkali hydrolysis), a me nā kaʻina ola (e laʻa, enzymatic digestion).
3. ʻO ka unuhi ʻana o ka cellulose:
Ma hope o ka hoʻomaʻamaʻa mua ʻana, lawe ʻia ka cellulose mai ka mea kanu. Hoʻohana ʻia kekahi mau ala no kēia kumu:
Nā Kūlana Mecharity: Nā Kūlana Mecharity e pili ana i keʻano o keʻano o ka mea kanu e hoʻokuʻu i nā mea kanu e hoʻokuʻu i nā fibers collulose. Hiki i kēia ke komo i ka wili, wili, a kaomi paha.
Nā Hana Kemika: ʻO nā ʻano hana kemika e pili ana i ka mālama ʻana i ka mea kanu me nā kemika e hoʻoheheʻe a hoʻohaʻahaʻa paha i nā ʻāpana non-cellulosic, e waiho ana ma hope o ka cellulose. Hoʻohana pinepine ʻia nā ʻano hana kemika i ka hydrolysis acid a me ka mālama alkaline.
Nā Hana Enzymatic: Hoʻohana nā ʻano Enzymatic i nā enzyme cellulase e wāwahi i ka cellulose i loko o kāna mau kō. ʻOi aku kēia kaʻina hana i ke koho a me ke kaiapuni i hoʻohālikelike ʻia me nā ʻano kemika.
4. Hoomaemae a Hoomaemae:
Ke lawe ʻia, hoʻomaʻemaʻe a hoʻomaʻemaʻe ʻia ka cellulose e wehe i nā haumia a loaʻa nā waiwai i makemake ʻia. Hiki i kēia ke komo i ka holoi ʻana, kānana, a me ka centrifugation e hoʻokaʻawale i nā fiber cellulose mai nā koena kemika a i ʻole nā mea ʻē aʻe.
5. Ka hoʻokumu ʻana a me ka hana ʻana:
Ma hope o ka hoʻomaʻemaʻe ʻana, hiki ke hana ʻia ka cellulose i nā ʻano like ʻole ma muli o kāna noi i manaʻo ʻia. Aia nā ʻano maʻamau:
Pulp: Hoʻohana ʻia ka pulp cellulose i ka ʻoihana pepa a me ka pepa pahu. Hiki ke hoʻomaʻemaʻe ʻia no ka loaʻa ʻana o nā pae like ʻole o ka mālamalama.
Nā Fibers: Hoʻohana ʻia nā fiber cellulose i nā lole a me nā lole. Hiki ke wili ʻia a ulana ʻia i lole.
Nā Kiʻiʻoniʻoni a me nā Membranes: Hiki ke hana ʻia ka cellulose i nā kiʻiʻoniʻoni ʻoniʻoni a i ʻole nā membrane i hoʻohana ʻia i ka hoʻopili ʻana, nā noi biomedical, a me ka kānana.
Nā Derivatives Kemika: Hiki ke hoʻololi kemika i ka cellulose e hana i nā derivatives me nā waiwai kikoʻī. ʻO nā laʻana he cellulose acetate (hoʻohana ʻia i ke kiʻi paʻi kiʻi a me nā textiles) a me carboxymethyl cellulose (hoʻohana ʻia i nā huahana meaʻai a me nā lāʻau lapaʻau).
Nanocellulose: Nanocellulose pili i cellulose fibers a i ole kristal me nanoscale ana. Loaʻa iā ia nā waiwai kūʻokoʻa a hoʻohana ʻia i nā noi holomua like ʻole e like me nā nanocomposites, nā mea biomedical, a me nā mea uila.
6. Nā noi:
Loaʻa ka cellulose i hana ʻia i nā noi ākea ma nā ʻoihana:
Pepa a me ka Packaging: ʻO ka Cellulose kahi mea waiwai nui i ka hana ʻana i ka pepa, ka pepa pahu, a me nā mea hoʻopili.
Textiles: ʻO ka pulupulu, kahi kumu o ka cellulose, hoʻohana nuiʻia i kaʻoihana lole no nā lole, nā lole home, a me nā loleʻoihana.
Meaʻai a me nā lāʻau lapaʻau: Hoʻohana ʻia nā derivatives Cellulose e like me nā mānoanoa, stabilizers, a me nā emulsifiers i nā huahana meaʻai a me nā mea hoʻoponopono lāʻau.
Nā Hoʻohana Biomedical: Hoʻohana ʻia nā mea i hoʻokumu ʻia i ka cellulose i nā ʻaʻahu ʻeha, nā scaffolds no ka ʻenekinia kiko, nā ʻōnaehana lawe lāʻau, a me nā implants olakino.
Hoʻoponopono Kaiapuni: Hiki ke hoʻohana ʻia nā mea pili i ka cellulose no ka hoʻoponopono ʻana i ke kaiapuni, e like me ka mālama ʻana i ka wai a me ka hoʻomaʻemaʻe ʻana i ka ʻaila.
Hiki ke hoʻololi hou i ka ikehu: Cellulose biomass hiki ke hoʻololi ʻia i biofuels e like me ka ethanol ma o nā kaʻina hana e like me ka fermentation a me ka hydrolysis enzymatic.
7. Nā Manaʻo Kaiapuni:
Loaʻa i ka hoʻoili ʻana o ka cellulose ka hopena o ke kaiapuni, e pili ana i ka hoʻohana ʻana i nā kemika a me ka ikehu. Ke hoʻomaka nei nā hoʻoikaika ʻana e hoʻomohala i nā ʻano hana hoʻomau e like me ka hoʻohana ʻana i nā kumu ikehu hou, hoʻemi i ka hoʻohana ʻana i ke kemika, a me ka hoʻokō ʻana i nā ʻōnaehana pani pani no ka wai a me ka hana hou ʻana.
8. Nā loina e hiki mai ana:
ʻO nā ʻano o ka wā e hiki mai ana i ka hana cellulose e pili ana i ka hoʻomohala ʻana i nā mea holomua me nā waiwai i hoʻonui ʻia, e like me nā plastic biodegradable, textiles akamai, a me nā nanocomposites. Ke piʻi aʻe nei ka hoihoi i ka hoʻohana ʻana i ka cellulose ma ke ʻano he mea hou a hoʻomau i nā mea i hoʻokumu ʻia i ka fossil i nā noi like ʻole.
ʻO ka hana cellulose e pili ana i nā ʻanuʻu, me ka unuhi ʻana, ka hoʻomaʻemaʻe, a me ka hana ʻana, e hana i nā ʻano huahana like ʻole me nā noi ʻoihana ākea. ʻO ka hoʻoikaika ʻana i ka hoʻoikaika ʻana i nā ʻano hana hana a me ka hoʻomohala ʻana i nā mea i hoʻokumu ʻia i ka cellulose hou e alakaʻi nei i ka holomua ma kēia kahua, me ka nānā ʻana i ka hoʻomau a me ke kuleana kaiapuni.
