Inzira yo gukora methyl selulose ether

Gukoramethyl selulose etherbirimo guhindura imiti ya selile binyuze muri etherification reaction. Methyl selulose (MC) ni amazi ya elegitoronike ya selile ikoreshwa cyane mubikorwa bitandukanye. Dore muri rusange incamake yuburyo bwo gukora methyl selulose ether:

1. Guhitamo Cellulose Inkomoko:

• Inzira itangirana no gutoranya isoko ya selile, mubisanzwe ikomoka kumiti cyangwa ipamba. Inkomoko ya selile yatoranijwe hashingiwe kubiranga ibyifuzo bya nyuma ya methyl selile.

2. Gusunika:

• Inkomoko yatoranijwe ya selile ikora pulping, inzira igabanya fibre muburyo bukoreshwa neza. Gusunika birashobora kugerwaho hakoreshejwe uburyo bwa mashini cyangwa imiti.

3. Gukora Cellulose:

• Cellulose isunitswe noneho ikorwa mukuvura umuti wa alkaline. Iyi ntambwe igamije kubyimba fibre ya selile, bigatuma irushaho gukora mugihe gikurikiraho etherification.

4. Igisubizo cya Etherification:

• Cellulose ikora ikora etherification, aho amatsinda ya ether, muriki gihe, methyl matsinda, yinjizwa mumatsinda ya hydroxyl kumurongo wa polymer.
• Imyitwarire ya etherification ikubiyemo gukoresha imiti ya methylating nka sodium hydroxide na methyl chloride cyangwa dimethyl sulfate. Imiterere yimyitwarire, harimo ubushyuhe, umuvuduko, nigihe cyo kubyitwaramo, bigenzurwa neza kugirango ugere kurwego rwifuzwa rwo gusimburwa (DS).

5. Kutabogama no Gukaraba:

• Nyuma ya etherification reaction, ibicuruzwa bitagira aho bibogamiye kugirango bikureho alkali irenze. Intambwe zo gukaraba zirakorwa kugirango imiti isigara hamwe n’umwanda.

6. Kuma:

• Cellulose isukuye kandi methylated yumye yumishijwe kugirango ibone ibicuruzwa bya methyl selile ya nyuma muburyo bwa poro cyangwa granules.

7. Kugenzura ubuziranenge:

• Uburyo butandukanye bwo gusesengura, harimo na magnetiki resonance (NMR) spekitroscopi, Fourier-transform infrared (FTIR) spekitroscopi, na chromatografiya, ikoreshwa mugucunga ubuziranenge. Urwego rwo gusimbuza (DS) nikintu gikomeye gikurikiranwa mugihe cyo gukora.

8. Gutegura no gupakira:

• Methyl selulose ether noneho ikorwa mubyiciro bitandukanye kugirango ihuze ibisabwa byihariye bya porogaramu zitandukanye. Impamyabumenyi zitandukanye zirashobora gutandukana mubwiza bwazo, ingano yingingo, nibindi bintu.
• Ibicuruzwa byanyuma bipakiye kugirango bikwirakwizwe.

Ni ngombwa kumenya ko imiterere yihariye na reagent zikoreshwa muri reaction ya etherification irashobora gutandukana bitewe nuburyo nyirubwite akora hamwe nibintu byifuzwa bya methyl selulose. Methyl selulose isanga porogaramu mubikorwa byibiribwa, imiti, ubwubatsi, nizindi nzego bitewe nubushobozi bwayo bwo gukemura amazi nubushobozi bwo gukora firime.
