Inzira yo gukora methyl selulose ether

Gukora methyl selulose ether bikubiyemo uburyo bwo guhindura imiti ikoreshwa kuri selile, polymer karemano ikomoka kurukuta rwibimera.Methyl selulose (MC) iboneka mugutangiza amatsinda ya methyl mumiterere ya selile.Inzira isanzwe ikubiyemo intambwe zikurikira:

Ibikorwa byo gukoraMethyl Cellulose Ether:

1. Ibikoresho bito:

• Inkomoko ya Cellulose: Cellulose iboneka mu biti cyangwa ku bindi bimera.Ni ngombwa gutangirana na selile nziza yo mu rwego rwo hejuru nkibikoresho fatizo.

2. Umuti wa Alkali:

• Cellulose ikorerwa alkali (alkalisation) kugirango ikore ingoyi ya selile.Ibi bikunze gukorwa hakoreshejwe sodium hydroxide (NaOH).

3. Igisubizo cya Etherification:

• Methylation Reaction: Cellulose ikora noneho ikorerwa methylation reaction, aho methyl chloride (CH3Cl) cyangwa dimethyl sulfate (CH3) 2SO4 ikoreshwa cyane.Iyi reaction itangiza amatsinda ya methyl kumurongo wa selile.
• Imiterere yimyitwarire: Igisubizo gikorwa mubushyuhe bugenzurwa nubushyuhe bwumuvuduko kugirango wizere ko urwego rusimburwa (DS) no kwirinda ingaruka.

4. Kutabogama:

• Uruvangitirane ruvanze rudafite aho rubogamiye kugirango rukureho alkali irenze ikoreshwa mugihe cyo gukora na methylation intambwe.Mubisanzwe bikorwa wongeyeho aside.

5. Gukaraba no kuyungurura:

• Ibicuruzwa bivamo byogejwe neza kandi birayungurura kugirango bikureho umwanda, imiti idakozwe, nibindi bicuruzwa.

6. Kuma:

• Methyl selulose itose noneho irumishwa kugirango ibone ibicuruzwa byanyuma muburyo bwifu.Hafashwe ingamba zo kugenzura uburyo bwo kumisha kugirango hirindwe kwangirika kwa selile.

7. Kugenzura ubuziranenge:

• Ingamba zo kugenzura ubuziranenge zishyirwa mubikorwa mugihe cyose kugirango harebwe ibimenyetso byifuzwa bya selile ya methyl, harimo urugero rwo gusimbuza, uburemere bwa molekile, nibindi bintu bifatika.

Ibitekerezo by'ingenzi:

1. Impamyabumenyi yo gusimburana (DS):

• Urwego rwo gusimbuza bivuga impuzandengo y'amatsinda ya methyl yatangijwe kuri anhydroglucose murwego rwa selile.Nibintu bikomeye bigira ingaruka kumiterere yibicuruzwa bya methyl ya nyuma.

2. Ibisabwa:

• Guhitamo reaction, ubushyuhe, umuvuduko, nigihe cyo kubyitwaramo bigenzurwa neza kugirango ugere kuri DS wifuza no kwirinda ingaruka zitifuzwa.

3. Ibicuruzwa bitandukanye:

• Inzira yo gukora irashobora guhindurwa kugirango itange methyl selulose ifite ibintu byihariye bigenewe porogaramu zitandukanye.Ibi birashobora kubamo gutandukana muri DS, uburemere bwa molekile, nibindi bintu.

4. Kuramba:

• Ibikorwa bigezweho byo gukora akenshi bigamije kubungabunga ibidukikije, urebye ibintu nkisoko ya selile, gukoresha imiti yangiza ibidukikije, no gucunga imyanda.

Ni ngombwa kumenya ko amakuru arambuye yuburyo bwo gukora ashobora gutandukana hagati yabayikora kandi ashobora kuba arimo intambwe yihariye.Byongeye kandi, kugenzura no gutekereza ku mutekano ni ngombwa mu gutunganya imiti ikoreshwa muri gahunda.Ababikora mubisanzwe bakurikiza amahame yinganda ningamba zo kugenzura ubuziranenge kugirango barebe umusaruro uhoraho kandi wizewe wa methyl selulose ether.
