Gutegura eteri za selulose

Imyiteguro yaeteri za selulosebikubiyemo guhindura cellulose karemano ya polymer binyuze mu buryo bwa shimi binyuze mu buryo bwa etherification. Ubu buryo bushyira amatsinda ya ether ku matsinda ya hydroxyl y'urunigi rwa polymer ya cellulose, biganisha ku ikorwa rya ether za cellulose zifite imiterere yihariye. Ether za cellulose zikunze gukoreshwa cyane zirimo Hydroxypropyl Methylcellulose (HPMC), Carboxymethyl Cellulose (CMC), Hydroxyethyl Cellulose (HEC), Methyl Cellulose (MC), na Ethyl Cellulose (EC). Dore incamake rusange y'uburyo bwo gutegura:

1. Gushakisha Selilulosi:

• Iyi gahunda itangirira ku gushaka selulosi, ubusanzwe ikomoka ku giti cyangwa ipamba. Guhitamo isoko ya selulosi bishobora kugira ingaruka ku miterere y'umusaruro wa nyuma wa selulosi.

2. Gutera ibinure:

• Selulosi ikoreshwa mu gusya imigozi kugira ngo ishobore kuyigabanyamo ibice. Ibi bishobora kuba birimo uburyo bwo kuyisya hakoreshejwe ikoranabuhanga cyangwa imiti.

3. Gusukura:

• Selulosi irasukurwa kugira ngo ikureho imyanda, lignin, n'ibindi bice bitari selulosi. Iyi ntambwe yo gusukura ni ingenzi kugira ngo ubone ibikoresho bya selulosi byiza cyane.

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

• Selulosi isukuye inyura mu buryo bwa etherification, aho amatsinda ya ether yinjizwa mu matsinda ya hydroxyl ari ku muyoboro wa polymer wa selulosi. Guhitamo ibikoresho bitanga etherization n'imiterere y'ibizamini biterwa n'umusaruro wa ether wa selulosi wifuza.
• Ibintu bisanzwe bikoreshwa mu gushyushya umwuka birimo ethylene oxide, propylene oxide, sodium chloroacetate, methyl chloride, n'ibindi.

5. Kugenzura Ibipimo by'Uburyo bwo Gusubiza:

• Uburyo bwo gupima ubushyuhe, igitutu, na pH bigenzurwa neza kugira ngo hagerwe ku rugero rwifuzwa rwo gusimbuza (DS) no kwirinda ingaruka mbi.
• Imiterere y'ibinyabutabire ikunze gukoreshwa, kandi pH y'uruvange rw'ibinyabutabire ikurikiranwa neza.

6. Kugabanya no gukaraba:

• Nyuma yo gushya, icyo gicuruzwa gikunze gukurwaho kugira ngo gikureho ibintu bidafite akamaro cyangwa ibindi bikomokaho. Iyi ntambwe ikurikirwa no kozwa neza kugira ngo haveho imiti n'imyanda bisigaye.

7. Kumisha:

• Selulosi isukuye kandi ikozwe mu buryo bwa eteri yumishwa kugira ngo haboneke umusaruro wa nyuma wa selulosi mu buryo bw'ifu cyangwa granular.

8. Igenzura ry'Ubuziranenge:

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

9. Uburyo bwo gukora no gupakira:

• Hanyuma, eteri ya selulosi ikorwa mu byiciro bitandukanye kugira ngo ihuze n'ibisabwa byihariye mu bikorwa bitandukanye. Ibicuruzwa bya nyuma bipakirwa kugira ngo bikwirakwizwe.

Gutegura eteri za selulosi ni inzira igoye cyane isaba kugenzura neza imiterere y’ibisubizo kugira ngo ugere ku miterere wifuza. Uburyo eteri za selulosi zikoreshwa mu buryo butandukanye butuma zikoreshwa mu nganda zitandukanye, harimo imiti, ibiribwa, ubwubatsi, irangi, n'ibindi.
