Eteri ya selulosi

Eteri ya selulosiikorwa muri selulosi binyuze mu gukora eteri ya eteri imwe cyangwa nyinshi hamwe no gusya byumye. Dukurikije imiterere itandukanye y'ibinyabutabire bya eteri, eteri za selulosi zishobora kugabanywamo eteri za anionic, cationic na nonionic. Eteri za selulosi za ionic zirimo ahaninieteri ya carboxymethyl cellulose (CMC)eteri za cellulose zitari ionic zirimo ahaninieteri ya methyl cellulose (MC),eteri ya hydroxypropyl methyl cellulose (HPMC)na eteri ya hydroxyethyl cellulose.Eteri ya Chlorine (HC)n'ibindi. Eteri zitari ionic zigabanyijemo eteri zishonga mu mazi na eteri zishonga mu mavuta, naho eteri zitari ionic zishonga mu mazi zikoreshwa cyane cyane mu bintu bya morti. Iyo hari iyoni za kalisiyumu, eteri ya cellulose ya ionic ntabwo ihindagurika, bityo ntikunze gukoreshwa mu bintu byumye bivanze na morti bikoresha sima, lime yaciwe, nibindi nk'ibikoresho byo gusima. Eteri zitari ionic zishonga mu mazi zikoreshwa cyane mu nganda z'ibikoresho by'ubwubatsi kubera ko zihamye kandi zigafata amazi.

Imiterere ya shimi ya eteri ya selulosi

Buri eteri ya selulosi ifite imiterere y'ibanze ya selulosi - imiterere ya Anhydroglucose. Mu gihe cyo gukora eteri ya selulosi, fibre ya selulosi ibanza gushyushywa mu gisubizo cya alkaline, hanyuma igaterwa umuti uvura. Umuti wa fibre urasukurwa ugaseswa kugira ngo ukore ifu imwe ifite ubugari runaka.

Mu ikorwa rya MC, methyl chloride ni yo yonyine ikoreshwa nk'ikintu gihindura etherification; uretse methyl chloride, propylene oxide nayo ikoreshwa mu kubona amatsinda asimbura hydroxypropyl mu ikorwa rya HPMC. Ether zitandukanye za cellulose zifite methyl na hydroxypropyl substitution ratios zitandukanye, ibyo bigira ingaruka ku bufatanye bw'ibinyabuzima n'ubushyuhe bwa gelation bw'ibisubizo bya cellulose ether.
