Ni ubuhe bwoko bwa eteri ya Cellulose?

Eteri za selulosi ni itsinda ry’ubwoko butandukanye bwa polimeri zikomoka kuri selulosi, polysaccharide karemano iboneka mu bimera. Zikoreshwa cyane mu nganda zitandukanye, harimo ubwubatsi, imiti, ibiribwa, amavuta yo kwisiga, no kwita ku buzima bwite, bitewe n’imiterere yazo yihariye n’uburyo zikoreshwa mu buryo butandukanye. Dore amwe mu moko asanzwe ya eteri ya selulosi:

1. Selirulose ya Methyl (MC):
   • Selulosi ya Methyl ikorwa binyuze mu kuvura selulosi hifashishijwe methyl chloride kugira ngo amatsinda ya methyl ashyirwe ku mugongo wa selulosi.
   • Irashongeshwa mu mazi akonje kandi ikora ibisubizo bisobanutse kandi bitose.
   • MC ikoreshwa nk'ikintu gikomeza ubushyuhe, gifata, kandi gikomeza ibintu mu buryo butandukanye, harimo ibikoresho by'ubwubatsi (urugero: mortiers zishingiye kuri sima, plasters zishingiye kuri gypsum), ibiryo, imiti, n'ibikoresho byo kwita ku buzima bw'umuntu ku giti cye.
2. Selirulose ya Hydroxyethyl (HEC):
   • Hydroxyethyl cellulose ikorwa binyuze mu guhuza cellulose na ethylene oxide kugira ngo itsinda rya hydroxyethyl rishyirwe ku mugongo wa cellulose.
   • Irashongesha mu mazi akonje kandi ikora ibisubizo bisobanutse neza kandi bitose kandi bifite ubushobozi bwiza bwo kubika amazi.
   • HEC ikunze gukoreshwa nk'ikintu gikomeza ubushyuhe, gihindura imiterere y'amaraso, kandi gihindura filime mu marangi, kole, ibikoresho byo kwiyitaho, ndetse n'imiti.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Hydroxypropyl methyl cellulose ikorwa binyuze mu gushyira hydroxypropyl na methyl groups ku mugongo wa cellulose.
   • Igaragaza imiterere isa na methyl cellulose na hydroxyethyl cellulose, harimo gushonga kw'amazi, ubushobozi bwo gukora filime, no kubika amazi.
   • HPMC ikoreshwa cyane mu bikoresho by'ubwubatsi (urugero: kole z'amatafari, sima, ibintu byigenga), ndetse no mu miti, ibiryo, n'ibikoresho byo kwiyitaho.
4. Selilulose ya karboksimetili (CMC):
   • Selulosi ya karuboksimeti ikomoka kuri selulosi mu kuyitera umuti wa sodiyumu hidroksidi na aside monokloroasetike kugira ngo hashyirwemo amatsinda ya karuboksimeti.
   • Irashongesha mu mazi kandi ikora ibisubizo bisobanutse neza, binanutse kandi bifite ubushobozi bwiza bwo gukurura, gutuza no kubika amazi.
   • CMC ikoreshwa cyane nk'ikintu gihindura imiterere y'ibiryo, imiti, imyenda, impapuro, n'ibindi bikoresho by'ubwubatsi.
5. Selirulose ya Ethyl (EC):
   • Selulosi ya ethyl ikorwa binyuze mu guhuza selulosi na ethyl chloride kugira ngo itsinda rya ethyl rishyirwe ku mugongo wa selulosi.
   • Ntishongera mu mazi ariko ishongera mu bintu bishongera ibinyabuzima nka ethanol na chloroform.
   • EC ikunze gukoreshwa nk'ikintu gikoreshwa mu gukora filime, gufunga no gusiga irangi mu miti, mu biribwa, mu mavuta yo kwisiga, no mu nganda.

Izi ni zimwe mu moko ya eteri ya selulosi ikoreshwa cyane, buri imwe itanga imiterere n'inyungu zidasanzwe ku bikorwa bitandukanye. Hari n'izindi eteri za selulosi zihariye, zijyanye n'ibikenewe mu nganda zitandukanye.
