Gịnị bụ ụzọ igbari cellulose ether?

Ịgbasa ethers cellulose nwere ike ịbụ nzọụkwụ dị mkpa na ụlọ ọrụ dị iche iche dị ka ọgwụ, nri, textiles, na ihe owuwu.Cellulose ethersA na-eji ya eme ihe n'ọtụtụ ebe n'ihi njirimara ha dị ka ịgba, njide, imepụta ihe nkiri, na nkwụsi ike. Otú ọ dị, adịghị ike ha na ọtụtụ ihe mgbaze nkịtị nwere ike ịkpata nsogbu. E mepụtala ọtụtụ ụzọ iji gbazee ethers cellulose nke ọma.

Ihe mgbaze organic:

Mmanya na-aba n'anya: mmanya na-egbu egbu dị ala dị ka ethanol, methanol, na isopropanol nwere ike igbari ethers cellulose ruo n'ókè ụfọdụ. Otú ọ dị, ha nwere ike ọ gaghị adị mma maka ụdị cellulose ethers niile ma nwee ike ịchọ okpomọkụ dị elu.
Ngwakọta mmanya na-aba n'anya: A na-ejikarị ngwakọta nke diethyl ether na ethanol ma ọ bụ methanol eme ihe iji gbazee ethers cellulose. Ihe mgbaze ndị a na-enye ezigbo solubility ma na-ejikarị na ntọala ụlọ nyocha.
Ketones: Ụfọdụ ketones dị ka acetone na methyl ethyl ketone (MEK) nwere ike igbari ụfọdụ ụdị cellulose ethers. A na-eji acetone eme ihe n'ọtụtụ ebe n'ihi ọnụ ahịa dị ala na ịdị irè ya.
Esters: Esters dị ka ethyl acetate na butyl acetate nwere ike igbari cellulose ethers nke ọma. Agbanyeghị, ha nwere ike ịchọ ikpo ọkụ iji nweta mgbasa zuru oke.

Ihe ngwọta mmiri:

Ngwọta Alkaline: Enwere ike ịgbaze ethers cellulose na ngwọta alkaline dị ka sodium hydroxide (NaOH) ma ọ bụ potassium hydroxide (KOH). Ihe ngwọta ndị a hydrolyze cellulose ethers na-etolite alkali metal salts, nke soluble.
Ngwọta Amonia: A pụkwara iji ngwọta Amonia (NH3) mee ihe iji gbazee ethers cellulose site n'ịkpụ ammonium salts nke ether.
Hydroxyalkyl Urea Solutions: Hydroxyalkyl urea Solution, dị ka hydroxyethyl urea ma ọ bụ hydroxypropyl urea, nwere ike igbari cellulose ethers nke ọma, karịsịa ndị nwere obere ogo nke nnọchi.

Mmiri Ionic:

Mmiri mmiri ion bụ nnu organic nke bụ mmiri mmiri na obere okpomọkụ, na-adịkarị n'okpuru 100 Celsius. Achọpụtala ụfọdụ mmiri mmiri ion na-agbari ethers cellulose nke ọma na-enweghị mkpa ọnọdụ siri ike. Ha na-enye uru dị ka mgbanwe dị ala, nkwụsi ike nke okpomọkụ dị elu, na mweghachi.

Ngwakọta Ngwakọta Ihe mgbaze:

Ijikọta ihe mgbaze dị iche iche nwere ike mgbe ụfọdụ ịkwalite solubility nke ether cellulose. Dịka ọmụmaatụ, ngwakọta nke mmiri nwere ihe mgbaze dị ka dimethyl sulfoxide (DMSO) ma ọ bụ N-methyl-2-pyrrolidone (NMP) nwere ike imeziwanye ihe mgbaze.
A na-ejikarị echiche Hansen Solubility Parameters arụ ọrụ iji chepụta sistemu ihe mgbaze agwakọta dị mma maka igbari ethers cellulose site na ịtụle paramita solubility nke ihe mgbaze onye ọ bụla na mmekọrịta ha.

Ụzọ anụ ahụ:

Mechanical Shearing: High-shiee Ịgwakọta ma ọ bụ sonication nwere ike inye aka na-achụsasị cellulose ethers na ihe mgbaze na melite mgbasa kinetics.
Njikwa okpomọkụ: Okpomọkụ dị elu nwere ike ịkwalite solubility nke cellulose ethers na ụfọdụ ihe mgbaze, ma a ghaghị ịkpachara anya iji zere mmebi nke polymer.

Mgbanwe kemịkalụ:

N'ọnọdụ ụfọdụ, mgbanwe kemịkalụ nke cellulose ethers nwere ike imeziwanye ihe ndị na-edozi ahụ. Dịka ọmụmaatụ, iwebata otu hydrophobic ma ọ bụ ịbawanye ogo nke nnọchi nwere ike ime ka ethers cellulose na-agbaze na ihe mgbaze organic.

Ngwọta Micellar:

Surfactants nwere ike na-etolite micelles na ngwọta, nke nwere ike solubilizecellulose ethers. Site n'imezigharị ntinye uche na ọnọdụ ngwọta, ọ ga-ekwe omume igbari ethers cellulose nke ọma.
N'ikpeazụ, nhọrọ nke usoro maka igbasa cellulose ethers na-adabere na ihe ndị dị ka ụdị cellulose ether, solubility chọrọ, echiche gburugburu ebe obibi, na ngwa a chọrọ. Usoro ọ bụla nwere uru na njedebe ya, ndị nchọpụta na-aga n'ihu na-enyocha ụzọ ọhụrụ iji meziwanye mgbasa nke ethers cellulose na ihe mgbaze dị iche iche.
