Cellulosics na-ezo aka na otu ihe ndị sitere na cellulose, nke bụ polymer organic kasị ukwuu na Ụwa na akụkụ bụ isi nke mgbidi cell osisi.Cellulose bụ polysaccharide linear nke mejupụtara nkeji glucose ugboro ugboro jikọtara ya na β(1→4) glycosidic bonds.

Enwere ike kewaa ihe cellulosic n'ụzọ sara mbara ụzọ abụọ: eke na sịntetik.

Cellulosics eke:

1. Osisi osisi: E sitere na eriri osisi, pulp osisi bụ isi iyi nke cellulose eji na ụlọ ọrụ dị iche iche, gụnyere ime akwụkwọ, textiles, na ihe owuwu.
2. Owu: Ajị anụ, nke a na-enweta site na ntutu mkpụrụ nke osisi owu, mejupụtara ihe fọrọ nke nta ka ọ bụrụ cellulose.A na-eji owu na-emepụta ihe n'ọtụtụ ebe n'ihi ịdị nro ya, ume iku ume, na ịmịkọrọ ya.
3. Hemp: eriri hemp, nke ewepụtara site na ị ga-esi na osisi hemp, nwere cellulose ma ejiri ya mee ihe na textiles, mpempe akwụkwọ, na ihe ndị mejupụtara.
4. Bamboo: Fiber bamboo, nke sitere na pulp nke osisi achara, bara ụba na cellulose ma na-arụ ọrụ n'ichepụta akwa, yana n'ichepụta akwụkwọ na ihe ụlọ.

Cellulosics sịntetik:

1. Cellulose eweghachitere: Emepụtara ya site na mgbaze nke cellulose na ihe mgbaze, dị ka cuprammonium hydroxide ma ọ bụ viscose, na-esote extrusion n'ime bath coagulation.Ihe cellulose emegharịrị gụnyere viscose rayon, lyocell (Tencel), na cellulose acetate.
2. Cellulose Esters: Mwepụta cellulose emezigharịrị nke kemịkalụ enwetara site na mmeghachi omume esterification na acid dị iche iche.Esters cellulose nkịtị gụnyere cellulose acetate, cellulose nitrate (celluloid), na cellulose acetate butyrate.Ihe ndị a na-achọta ngwa na mmepụta ihe nkiri, mkpuchi, na plastik.

Ngwa nke Cellulosics:

1. A na-eji akwa akwa: eriri cellulosic, ma eke (dịka ọmụmaatụ, owu, hemp) na nke emegharịrị (dịka, viscose rayon, lyocell), na-eji ọtụtụ ihe na-emepụta akwa maka uwe, akwa ụlọ, na akwa ụlọ ọrụ.
2. Mpempe akwụkwọ na nkwakọ ngwaahịa: Mpekere osisi, nke sitere na isi mmalite cellulosic, na-eje ozi dị ka ihe bụ isi maka imepụta akwụkwọ na ihe nkwakọ ngwaahịa.Eriri cellulosic na-enye ike, nnabata, na ibipụta ngwaahịa akwụkwọ.
3. Ihe eji ewuru ihe: A na-eji ihe cellulosic, dị ka osisi na achara, na-arụ ọrụ maka ihe arụrụ arụ (dịka ọmụmaatụ, osisi, plywood) na ihe ịchọ mma (dịka ọmụmaatụ, ala siri ike, ogwe achara).
4. Ngwaahịa Nlekọta Onwe Onye: A na-eji ihe ndị sitere na cellulose arụ ọrụ na ngwaahịa nlekọta onwe onye, ​​gụnyere nhichapụ, anụ ahụ, na ngwaahịa ịdị ọcha na-amịkọrọ ọnụ, n'ihi ịdị nro ha, ike ha na ihe ndị dị ndụ.
5. Nri na ọgwụ: A na-eji ihe ndị na-emepụta cellulose, dị ka microcrystalline cellulose na carboxymethylcellulose, dị ka ihe ndị na-emepụta nri na ọgwụ maka mmepụta ha siri ike, na-eme ka ha guzosie ike na njide.

Uru nke Cellulosics:

1. Emeghari ohuru na ihe ndi ozo: A na-enweta ihe ndi cellulosic site na isi mmalite osisi a na-emeghari ma di ndu, na-eme ka ha buru uzo ozo na gburugburu ebe obibi na polymers synthetic.
2. Ntughari: Cellulosics na-egosipụta ọtụtụ ihe onwunwe na arụ ọrụ, na-enye ohere maka ngwa dị iche iche n'ofe ụlọ ọrụ, site na textiles na ọgwụ.
3. Nnweta: Cellulose dị ukwuu n'okike, nwere isi mmalite sitere na osisi na owu ruo achara na hemp, na-eme ka ọ bụrụ ihe na-agbanwe agbanwe na ntụkwasị obi maka iji ụlọ ọrụ eme ihe.
4. Biocompatibility: Ọtụtụ ihe cellulosic na-ejikọta ya na ihe na-adịghị egbu egbu, na-eme ka ha dị mma maka iji nri, ọgwụ na ngwa ahụike.

Na nchịkọta, cellulosics gụnyere ihe dị iche iche nke sitere na cellulose, na-enye mgbanwe, nkwado na biocompatibility gafee ngwa dị iche iche na ụlọ ọrụ dị ka textiles, mpempe akwụkwọ, ihe owuwu, nlekọta onwe onye, ​​​​na nlekọta ahụike.
