Uburyo bwo gukora eteri ya methyl cellulose

Gukoraeteri ya methyl celluloseBikubiyemo guhindura selulosi hakoreshejwe uburyo bwo gukwirakwiza eteri. Selulosi ya Methyl (MC) ni selulosi ishongeshwa n'amazi ikoreshwa cyane mu nganda zitandukanye. Dore incamake rusange y'uburyo bwo gukora eteri ya methyl selulosi:

1. Guhitamo aho Selilulosi Ituruka:

• Igikorwa gitangirana no guhitamo isoko ya selulosi, ikunze gukomoka ku giti cyangwa ipamba. Isoko ya selulosi itoranywa hashingiwe ku miterere y’umusaruro wa nyuma wa selulosi ya methyl.

2. Gutera ibinure:

• Isoko ya selulosi yatoranijwe inyura mu gusya, inzira igabanya imigozi mu buryo bworoshye bworoshye kuyitunganya. Gusya bishobora kugerwaho hakoreshejwe uburyo bwa mekanike cyangwa ubwa shimi.

3. Gukora kwa Selulose:

• Hanyuma selulose ikozwe mu buryo bwa pulped irakora ikoresheje umuti wa alkaline. Iyi ntambwe igamije kuzura imigozi ya selulose, bigatuma irushaho gukora neza mu gihe cy'ihinduka rya etherification.

4. Uburyo bwo guhindura imiterere y'amaraso mu buryo bwa etherization:

• Selulosi ikora inyura mu buryo bwa etherification, aho amatsinda ya ether, muri iki gihe, amatsinda ya methyl, yinjizwa mu matsinda ya hydroxyl ari ku muyoboro wa polymer wa selulosi.
• Uburyo bwo guhindura imiterere y'ibintu hakoreshejwe imiti nka sodium hydroxide na methyl chloride cyangwa dimethyl sulfate. Imiterere y'uburyo ibintu bikorwamo, harimo ubushyuhe, igitutu, n'igihe ibintu bikorwamo, bigenzurwa neza kugira ngo hagerwe ku rugero rwifuzwa rwo gusimbuza (DS).

5. Kugabanya no gukaraba:

• Nyuma yo gushya, icyo gikoresho kirakurwamo alkali nyinshi. Intambwe zo gukaraba nyuma zikorwa kugira ngo haveho imiti n'imyanda bisigaye.

6. Kumisha:

• Selulosi isukuye kandi ifite methyl yumishwa kugira ngo haboneke umusaruro wa nyuma wa methyl cellulose ether mu buryo bw'ifu cyangwa utubumbe.

7. Igenzura ry'Ubuziranenge:

• Uburyo butandukanye bwo gusesengura, harimo spectroscopy ya nuclei magnetic resonance (NMR), spectroscopy ya infrared ya Fourier-transform (FTIR), na chromatography, bukoreshwa mu kugenzura ubuziranenge. Igipimo cyo gusimbuza (DS) ni igipimo cy'ingenzi gikurikiranwa mu gihe cyo gukora.

8. Uburyo bwo gukora no gupakira:

• Hanyuma, eteri ya methyl cellulose ikorwa mu byiciro bitandukanye kugira ngo ihuze n'ibisabwa mu buryo butandukanye. Ibyiciro bitandukanye bishobora gutandukana mu buryo bworoshye, ingano y'uduce, n'ibindi bintu biyiranga.
• Ibicuruzwa bya nyuma bipakirwa kugira ngo bikwirakwizwe.

Ni ngombwa kumenya ko imiterere yihariye n'ibisubizo bikoreshwa mu gukora etherification bishobora gutandukana bitewe n'imikorere y'uruganda ndetse n'imiterere yifuzwa y'umusaruro wa methyl cellulose. Methyl cellulose ikoreshwa mu nganda z'ibiribwa, imiti, ubwubatsi, n'izindi nzego bitewe n'ubushobozi bwayo bwo gushonga mu mazi no gukora filime.
