Kedu ihe bụ cellulose fiber?

Cellulose eriribụ ihe fibrous nke sitere na cellulose, polysaccharide na-emekarị nke a na-achọta na mgbidi cell nke osisi. Cellulose bụ polymer organic kasị ukwuu n'ụwa ma na-eje ozi dị ka akụkụ bụ isi nke mgbidi cell osisi, na-enye ike, isi ike, na nkwado maka anụ ahụ osisi. A na-eji eriri cellulose eme ihe n'ọtụtụ ebe na ụlọ ọrụ dị iche iche maka ike ya, ọdịdị ya, na biodegradability. Nke a bụ nkọwa nke eriri cellulose:

Isi mmalite nke cellulose fiber:

1. Ihe ọkụkụ: A na-enweta fiber cellulose nke ọma site na isi ihe ọkụkụ, gụnyere osisi, owu, hemp, bamboo, jute, flax, na akpa okpete. Ụdị osisi na akụkụ dị iche iche nwere ọnụọgụ dị iche iche na ụdị cellulose fibers.
2. Ihe eji emeghari: A nwekwara ike nweta eriri cellulose site na mpempe akwụkwọ, kaadiboodu, textiles, na ihe mkpofu ndị ọzọ nwere cellulose site na usoro nhazi ma ọ bụ kemịkalụ.

Ụzọ nhazi:

1. Mechanical Pulping: A na-eji usoro eji arụ ọrụ, dị ka egweri, nnụcha, ma ọ bụ igwe nri, kewapụ eriri cellulose na ihe osisi ma ọ bụ akwụkwọ emegharịrị. Ntugharị igwe na-echekwa usoro okike nke eriri ahụ mana ọ nwere ike ibute ogologo eriri ogologo yana obere ịdị ọcha.
2. Kemịkalụ kemịkalụ: Usoro kemịkalụ, dị ka usoro kraft, usoro sulfite, ma ọ bụ usoro organosolv, gụnyere iji kemịkal na-agwọ ihe osisi iji gbarie lignin na ihe ndị ọzọ na-abụghị cellulosic, na-ahapụ n'azụ eriri cellulose dị ọcha.
3. Enzymatic Hydrolysis: Enzymatic hydrolysis na-eji enzymes gbarie cellulose ka ọ bụrụ shuga soluble, nke enwere ike ịgbanye n'ime mmanụ ndị dị ndụ ma ọ bụ ihe ndị ọzọ dị ndụ.

Njirimara nke Cellulose Fiber:

1. Ike: A maara eriri cellulose maka ike ha dị elu, isi ike, na ịdịte aka, na-eme ka ha dị mma maka ngwa nhazi na ụlọ ọrụ dị iche iche.
2. Absorbency: eriri cellulose nwere ihe ndị na-adọrọ adọrọ nke ọma, na-enye ha ohere ịmịnye ma na-ejigide mmiri, mmiri mmiri, na ísì. Nke a na-eme ka ha dị mma maka iji ihe ndị na-amị amị, dị ka akwa nhicha akwụkwọ, ihicha, na ngwaahịa ịdị ọcha.
3. Biodegradability: eriri cellulose bụ ihe na-emebi emebi na gburugburu ebe obibi, ebe ọ bụ na ụmụ nje nwere ike ịkụda ya ka ọ bụrụ ihe na-adịghị emerụ ahụ, dị ka mmiri, carbon dioxide, na ihe ndị dị ndụ.
4. Ihe mkpuchi okpomọkụ: Fiber cellulose nwere ihe mkpuchi ọkụ dị n'ime ya, na-eme ka ọ dị mma maka iji wuo ngwaahịa mkpuchi, dị ka mkpuchi cellulose, nke na-enyere aka melite arụmọrụ ike ma belata ụgwọ ọkụ na oyi.
5. Mmeghachi omume kemịkalụ: Fiber cellulose nwere ike ime mgbanwe kemịkalụ iji webata otu ndị na-arụ ọrụ ma ọ bụ gbanwee akụrụngwa ha maka ngwa akọwapụtara, dị ka cellulose ethers, esters, na usoro eji eme ọgwụ, ihe mgbakwunye nri na ngwa ụlọ ọrụ.

Ngwa nke Cellulose Fiber:

1. Akwụkwọ na Nkwakọ ngwaahịa: Cellulose fiber bụ ihe bụ isi ihe eji eme akwụkwọ, nke a na-eji na-emepụta akwụkwọ dị iche iche na ngwaahịa kaadiboodu, gụnyere akwụkwọ obibi akwụkwọ, ihe nkwakọ ngwaahịa, akwụkwọ anụ ahụ, na bọọdụ mkpọda.
2. A na-eji akwa akwa na uwe: A na-eji eriri cellulose, dị ka owu, linen, na rayon (viscose), na-emepụta akwa ákwà, yarns, na uwe, gụnyere uwe elu, uwe, jeans, na akwa nhicha.
3. Ihe eji arụ ọrụ: A na-eji eriri cellulose na-emepụta ihe ndị e ji osisi rụọ, dị ka particleboard, fiberboard, oriented strand board (OSB), na plywood, nakwa dị ka ihe mkpuchi na ihe mgbakwunye ihe.
4. Biofuels na Energy: Cellulose fiber na-eje ozi dị ka nri nri maka mmepụta biofuel, gụnyere ethanol, biodiesel, na biomass pellets, nakwa dị ka osisi cogeneration maka okpomọkụ na ike ike.
5. Nri na ọgwụ: A na-eji ihe ndị na-emepụta cellulose, dị ka methylcellulose, carboxymethylcellulose (CMC), na microcrystalline cellulose (MCC), dị ka thickeners, stabilizers, binders, and fillers in food products, pharmaceuticals, cosmetics, and personal care things.

Mmechi:

Fiber cellulose bụ ihe na-adịgide adịgide yana ngwa dị iche iche n'ofe ụlọ ọrụ, gụnyere ịde akwụkwọ, textiles, Construction, biofuels, food, and pharmaceuticals. Uba ya, mmeghari ohuru, na biodegradability na-eme ka ọ bụrụ nhọrọ mara mma maka ndị na-emepụta ihe na-achọ ihe omume gburugburu ebe obibi na arụmọrụ dị elu. Dị ka ụlọ ọrụ na-aga n'ihu na-ebute nkwado nkwado na nlekọta gburugburu ebe obibi, a na-atụ anya na eriri cellulose ga-arụ ọrụ dị mkpa na mgbanwe gaa na gburugburu akụ na ụba na-arụ ọrụ nke ọma.
