Cellulose ethers nuburyo bwo gutanga kimwe

Umusaruro waselile ethersikubiyemo urukurikirane rwimiti ihindura selile, bivamo ibikomoka kumiterere yihariye.Ibikurikira nubusobanuro rusange bwuburyo bukoreshwa mugukora selile ya selile:

1. Guhitamo Inkomoko ya Cellulose:

• Ether ya selile irashobora gukomoka ahantu hatandukanye nko gutema ibiti, kumpamba, cyangwa ibindi bikoresho bishingiye ku bimera.Guhitamo isoko ya selile irashobora guhindura ibiranga ibicuruzwa bya selile ya nyuma.

2. Gusunika:

• Inkomoko ya selile ikora kunyunyuza imitsi kugirango ikorwe neza.Gusunika birashobora kugerwaho hifashishijwe imashini, imiti, cyangwa guhuza uburyo bwombi.

3. Kwezwa:

• Cellulose isunitswe ikoreshwa muburyo bwo kweza kugirango ikureho umwanda, lignine, nibindi bikoresho bitari selile.Isuku ningirakamaro kugirango ubone ibikoresho bya selile nziza.

4. Gukora Cellulose:

• Cellulose isukuye ikora mukubyimba mumuti wa alkaline.Iyi ntambwe ningirakamaro kugirango selile irusheho kwitwara mugihe cya etherification ikurikira.

5. Igisubizo cya Etherification:

• Cellulose ikora ikora etherification, aho amatsinda ya ether yinjizwa mumatsinda ya hydroxyl kumurongo wa selile ya polymer.Ibikoresho bisanzwe bya etherifingi harimo okiside ya Ethylene, oxyde ya propylene, sodium chloroacetate, methyl chloride, nibindi.
• Igisubizo gikunze gukorwa mubihe bigenzurwa nubushyuhe, umuvuduko, na pH kugirango ugere kurwego rwifuzwa rwo gusimburwa (DS) no kwirinda ingaruka.

6. Kutabogama no Gukaraba:

• Nyuma ya reaction ya etherification, ibicuruzwa akenshi bidafite aho bibogamiye kugirango bikureho reagent zirenze cyangwa nibindi bicuruzwa.Intambwe zo gukaraba zirakorwa kugirango ikureho imiti isigaye n’umwanda.

7. Kuma:

• Cellulose isukuye kandi ya etherifile yumishijwe kugirango ibone ibicuruzwa bya selile ya nyuma ya poro cyangwa ifu ya granular.

8. Kugenzura ubuziranenge:

• Uburyo butandukanye bwo gusesengura, harimo na magnetiki resonance (NMR) spekitroscopi, Fourier-transform infrared (FTIR) spekitroscopi, na chromatografiya, ikoreshwa mugucunga ubuziranenge.DS ikurikiranirwa hafi kugirango ihamye.

9. Gutegura no kubishyira mu bikorwa:

• Ether ya selile noneho ikorwa mubyiciro bitandukanye kugirango ihuze ibisabwa byihariye bya porogaramu zitandukanye.Ethers zitandukanye za selile zikwiranye ninganda zitandukanye, nkubwubatsi, imiti, ibiryo, impuzu, nibindi byinshi.

Ni ngombwa kumenya ko uburyo bwihariye nibisabwa bishobora gutandukana ukurikije ibicuruzwa bya selile yifuza na progaramu igenewe.Ababikora akenshi bakoresha uburyo bwihariye kugirango babyaze selile selile ifite imitungo yihariye ijyanye no gukenera inganda zitandukanye.
