He aha ka Cellulose fiber?

ʻO ka fiber cellulosehe mea fibrous i loaʻa mai ka cellulose, he polysaccharide kūlohelohe i loaʻa i loko o nā paia cell o nā mea kanu. ʻO Cellulose ka polymer organik nui loa ma ka Honua a lawelawe ʻo ia ma ke ʻano he kumu kumu mua o nā pā hale mea kanu, hāʻawi i ka ikaika, rigidity, a me ke kākoʻo i nā ʻiʻo mea kanu. Hoʻohana nui ʻia ka fiber cellulose i nā ʻoihana like ʻole no kona ikaika, versatility, a me ka biodegradability. Eia kahi hiʻohiʻona o ka fiber cellulose:

Nā Puna o ka Cellulose Fiber:

1. Mea kanu: ʻO ka fiber Cellulose ka mea i loaʻa mai nā kumu mea kanu, me ka lāʻau, ka pulupulu, ka hemp, ka ʻohe, ka jute, ke olonā, a me ke kō. Aia nā ʻano mea kanu like ʻole a me nā ʻāpana like ʻole ka nui a me nā ʻano o nā fiber cellulose.
2. Nā Mea Hana Hou: Hiki ke kiʻi ʻia ka fiber cellulose mai ka pepa i hana hou ʻia, ka pahu pahu, nā lole lole, a me nā mea ʻōpala i loaʻa i ka cellulose ma o nā kaʻina hana mechanical a kemika.

Nā ʻano hana:

1. Mechanical Pulping: Hoʻohana ʻia nā ʻano mīkini, e like me ka wili, hoʻomaʻemaʻe, a wili paha, e hoʻokaʻawale i nā fiber cellulose mai nā mea kanu a i ʻole ka pepa hana hou. Mālama ka pulping mīkini i ke ʻano kūlohelohe o nā fiber akā hiki ke hopena i ka lōʻihi o ka fiber pōkole a me ka maʻemaʻe haʻahaʻa.
2. Pulping Kemika: ʻO nā hana kemika, e like me ke kaʻina hana kraft, ke kaʻina sulfite, a i ʻole ke kaʻina organosolv, e pili ana i ka mālama ʻana i nā mea kanu me nā kemika e hoʻopau i ka lignin a me nā mea ʻē aʻe non-cellulosic, e waiho ana ma hope o nā fiber cellulose maʻemaʻe.
3. Enzymatic Hydrolysis: Hoʻohana ka Enzymatic hydrolysis i nā enzymes e wāwahi i ka cellulose i loko o nā kō i hiki ke hoʻoheheʻe ʻia i loko o nā biofuels a i ʻole nā ​​​​mea biochemical ʻē aʻe.

ʻO nā pono o ka Cellulose Fiber:

1. Ka ikaika: Ua ʻike ʻia nā fibers Cellulose no ko lākou ikaika tensile kiʻekiʻe, ʻoʻoleʻa, a me ka lōʻihi, e kūpono ana iā lākou no nā noi hoʻolālā i nā ʻoihana like ʻole.
2. Absorbency: Loaʻa i nā fibers Cellulose nā mea hoʻoheheʻe maikaʻi loa, e ʻae iā lākou e hoʻopaʻa a mālama i ka makū, nā wai, a me nā mea ʻala. ʻO kēia ka mea kūpono no ka hoʻohana ʻana i nā mea hoʻoheheʻe, e like me nā kāwele pepa, nā holoi holoi, a me nā huahana maʻemaʻe.
3. Biodegradability: ʻO ka fiber cellulose he biodegradable a me ke kaiapuni, no ka mea, hiki ke wāwahi ʻia e nā microorganism i nā mea ʻino ʻole, e like me ka wai, carbon dioxide, a me nā mea ola.
4. Thermal Insulation: Loaʻa i nā fiber cellulose nā waiwai insulating thermal, e kūpono iā lākou no ka hoʻohana ʻana i ke kūkulu ʻana i nā huahana insulation, e like me ka cellulose insulation, e kōkua ana i ka hoʻomaikaʻi ʻana i ka ikehu a hoʻemi i nā kumukūʻai hoʻomehana.
5. Hoʻololi Kemika: Hiki i nā fiber cellulose ke hana i ka hoʻololi kemika e hoʻolauna i nā hui hana a hoʻololi paha i kā lākou mau waiwai no nā noi kikoʻī, e like me cellulose ethers, esters, a me nā derivatives i hoʻohana ʻia i nā lāʻau lapaʻau, nā mea hoʻohui meaʻai, a me nā noi ʻoihana.

Nā noi o ka Cellulose Fiber:

1. Ka Pepa a me ka Packaging: ʻO ka fiber cellulose ka mea mua no ka hana pepa, i hoʻohana ʻia e hana i nā ʻano pepa like ʻole a me nā huahana pahu pahu, me ka pepa paʻi, nā mea hoʻopili, pepa kiko, a me ka papa corrugated.
2. Nā lole a me nā lole: Hoʻohana ʻia nā fiber cellulose, e like me ka pulupulu, ke olonā, a me ka rayon (viscose), i ka hana textile e hana i nā lole, nā wili, a me nā mea lole, me nā pālule, nā lole, nā jeans, a me nā kāwele.
3. Nā Mea Hana Hana: Hoʻohana ʻia ka cellulose fiber i ka hana ʻana i nā huahana lāʻau i hana ʻia, e like me ka particleboard, fiberboard, oriented strand board (OSB), a me ka plywood, a me nā mea insulation a me nā mea hoʻohui.
4. ʻO Biofuels a me Energy: ʻO ka fiber cellulose he mea hānai no ka hana biofuel, me ka ethanol, biodiesel, a me nā pellet biomass, a me nā mea kanu cogeneration no ka hana wela a me ka mana.
5. Meaʻai a me nā lāʻau lapaʻau: Hoʻohana ʻia nā derivatives cellulose, e like me methylcellulose, carboxymethylcellulose (CMC), a me microcrystalline cellulose (MCC), e like me nā mānoanoa, stabilizers, binders, a me nā mea hoʻopiha i nā huahana meaʻai, nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā mea mālama pilikino.

Ka hopena:

ʻO ka fiber cellulose he mea maʻalahi a hoʻomau me ka nui o nā noi ma nā ʻoihana, me ka hana pepa, textiles, kūkulu, biofuels, meaʻai, a me nā lāʻau lapaʻau. ʻO kona nui, hoʻohou, a me ka biodegradability e lilo ia i koho maikaʻi no nā mea hana e ʻimi nei i nā mea eco-friendly a kiʻekiʻe. Ke hoʻomau nei nā ʻoihana i ka hoʻomau ʻana a me ka mālama ʻana i ke kaiapuni, manaʻo ʻia ka cellulose fiber e hana koʻikoʻi i ka hoʻololi ʻana i kahi hoʻokele waiwai ʻoi aku ka maikaʻi.
