Mmepụta nke mkpụrụ ndụ cellosuse gụnyere n'ụzọ kemịlị na-agbanwe agbanwe nke cellulose, nke sitere na osisi pulp ma ọ bụ owu, site na usoro mmeghachi omume kemịkal. A na-ahụkarị ụdị mkpụrụ osisi cell na-ahụkarị methyl cellulose (mc), hydroxyethythyl methyl methyl cellulose (hpmcyl), coulboxymythylylym cellulose (cmc), na ndị ọzọ. Usoro kpọmkwem nwere ike ịdị iche iche dabere na mkpụrụ osisi mkpụrụ osisi mkpụrụ osisi ahụ, mana usoro niile dị ka. Nke a bụ atụmatụ dị mfe:

General Nzọụkwụ maka ịme ndị eyers cellugul:

1. Isi mmalite:

• Ihe mbido bu sellose, na-enwetakarị ya na osisi pulp ma ọ bụ owu. The cellulose na-abụkarị n'ụdị mkpụrụ osisi na-acha ọcha.

2. Alkalization:

• A na-emeso cellulose na ngwọta alkaline, dịka sodium hydroxide (NaOh), iji mee ka otu Hydropose yie. Nzọụkwụ alkalization a dị oke mkpa maka ọzọ derivatization.

3. Ekele:

• A na-ewebata ogo Alkalation, ebe a na-ewebata otu dị iche iche na Cellulose Backbone. Typedị nke Ether akọwapụtara (Methyl, hydroxyethyl, hydroxyyl, carroxyyyl, carboxythyl, wdg) dabere na cellose ether chọrọ.
• Usoro e nwere ihe a ga-eme bụ mmeghachi omume nke cellose nwere ndị kwesịrị ekwesị, dịka:
  • Maka methyl cellulose (mc): ọgwụgwọ na duasfate sulfate ma ọ bụ methyl chloride.
  • Maka hydroxyethyth Cellulose (HEC): Ọgwụ na Ethlene Oxide.
  • Maka hydroxyylthyl methyl cellulose (hpmc): ọgwụgwọ na proslene oxide na methyl chloride.
  • Maka celloxythythythythylythym Cellulose (cmc): ọgwụgwọ na sodium chlorocetate.

4..

• Mgbe nzere gwụchara, ihe na-esite na Cellulose deeditive na-anọpụ iche iji wepu alkali ọ bụla. A na-asacha ngwaahịa ahụ iji kpochapụ adịghị ọcha na ngwaahịa.

5. Ọkụ na igwe:

• Efere celdigose ether a na-akpọnwụ iji wepu oke mmiri wee banye na ntụ ntụ. Enwere ike ịchịkwa nha uru sitere na ngwa achọrọ.

6. Njikwa dị mma:

• Ngwakọta Cellligose Ether na-agbanwe agbanwe iji hụ na ọ na-emezu nkọwapụta ụfọdụ, gụnyere viscesse, ihe nkesa, na akụrụngwa ndị ọzọ dị mkpa.

Ọ dị mkpa iburu n'uche na mmepụta nke ndị na-emepụta ọrụ pụrụ iche na-eji usoro achịkwa. Ọnọdụ, ndị na-eme ihe nkiri, na akụrụngwa eji nwere ike ịdị iche site na akụrụngwa achọrọ nke cellulose eather na ngwa ahụ chọrọ. Ọzọkwa, usoro nchekwa dị mkpa n'oge usoro mgbanwe kemịkalụ.
