Isi echiche na nhazi nke cellulose ether

Mkpụrụ osisi e nwere polmers sitere na cellose, nke na-eme polsackide na-ahụ na mgbidi cells. A na-eji usoro ndị ọrụ Cellugul n'ọtụtụ ụlọ ọrụ dị iche iche n'ihi ihe ndị ha pụrụ iche, nke gụnyere imegharị, ebe a na-eme ihe nkiri, na idozi ikike. Nke a bụ echiche dị mkpa na ọkwa nke sel:

Isi echiche:

1. Ihe Owulu Cellulose:
   • Mkpụrụ osisi na-ejikọ mkpụrụ osisi glucose jikọtara ọnụ site na Β (1 → 4) Glycosidic Agbụ. Ọ na-etolite ogologo oge, ahịrị ahịrị nke na-enye nkwado nhazi nke ịkọ mkpụrụ ndụ.
2. Ether:
   • A na-emepụta usoro mmepụta nke mkpụrụ osisi cellulose site na iwebata Other (-Och2Hah2oh) na hydroxyl nke celdlose molekuse molulu.
3. Ọrụ:
   • Okwu mmeghe nke ndị otu Eelt na-agbanwe kemịkal na anụ ahụ nke cellulose, na-enye ndị na-eme ihe nkiri pụrụ iche na-arụ ọrụ dị ka ị ga - agbasa, viscosity, vines, na usoro ihe nkiri.
4. Biodegrad:
   • Ahymers cellosuse bụ poodegrable polymers, nke pụtara na enwere ike imebi site na microorganisms na gburugburu ebe obibi, na-eduga na ngwaahịa ndị na-adịghị emerụ ahụ.

Nkewa:

A na-ekewapụta ndị na-eme ihe nkiri Cellulose dabere na ụdị Ether na-emepụtara na Cellulose moleku na ogo ha. A na-ejikarị evethers cellugul gụnyere:

1. Methyl cellulose (mc):
   • A na-emepụta methy cellulose site na iwebata Methyl (-och3) na-aga cellulose molekuse.
   • Ọ na-agbanye na mmiri oyi ma na-edobe usoro, ngwọta vious. A na-eji MC dị ka nke na-agba, sie ike, na ihe nkiri gara aga na ngwa dị iche iche.
2. Hydroxyethythythythythyth Cellulose (HEC):
   • A na-enweta hydroxyythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythyth na-ewebata hydroxyethyl (-Och2OH9OH) ndị otu cellulose.
   • Ọ na-egosipụta ụdị njigide mmiri siri ike na ihe ndị dị mma, na - eme ya kwesịrị ekwesị maka ojiji na eserese, adhesives, ịchọ mma, na ọgwụ.
3. Hydroxypylthylthth methyl cellulose (hpmc):
   • Hydroxypylthylthyl methyl cellulose bụ copolulymer nke methyl cellulose na hydroxyppyyl cellose.
   • Ọ na-enye nguzozi nke Njirimara dị ka mmiri mmiri, njikwa viscosit, na ihe nkiri. A na-eji HPMC mee ihe n'ọtụtụ ụlọ, ọgwụ na ngwaahịa nlekọta onwe ya.
4. Celloxymymym cellulose (cmc):
   • A na-emepụta cellulose celloxythylythythythythythylythyl (-och29) Otuto na-ahụ maka cellulose molulu.
   • Ọ na-agbanye mmiri na mmiri ma na-agbanwe agbanwe viscous na ezigbo ndị nwere ezigbo ike ma na-edozi edozi. A na-eji cmc nri, ọgwụ na ngwa ọrụ.
5. Ethyl Hydroxyethythyth Cellulose (ehec):
   • A na-enweta sellythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythy na-ewebata Ethyl na Hydroxyethyyl na Cellulose molulu.
   • Ọ na-egosipụta njigide mmiri, sie ike, na ihe ndị na-ada na rheulo na-atụnyere HEC. A na-eji ehec na ihe owuwu na ngwaahịa nlekọta onwe ya.
