Microcrystalline Cellulose (MCC) |9004-34-6
Ibicuruzwa bisobanura
Microcrystalline selulose ni ijambo ryibiti bitunganijwe neza kandi bikoreshwa nkibikoresho byandika, imiti igabanya ubukana, umusemburo wamavuta, emulisiferi, umugozi, hamwe numukozi wibyimbye mukubyara ibiryo.Uburyo bukunze gukoreshwa muburyo bwa vitamine cyangwa ibinini.Irakoreshwa kandi muburyo bwa plaque yo kubara virusi, nkuburyo bwa carboxymethylcellulose.Mu buryo bwinshi, selile ikora ibintu byiza.Ubusanzwe polymer ibaho, igizwe na glucose ibice bihujwe na 1-4 beta glycosidic.Iminyururu ya selulose igizwe hamwe nkuko microfibril izunguruka hamwe murukuta rw'utugingo ngengabuzima.Buri microfibril yerekana urwego rwo hejuru rwimiterere-itatu yimbere ihuza imiterere ya kristaline idashobora gushonga mumazi kandi idashobora kwihanganira reagent.Hariho, ariko, ibice bigabanutse cyane bya microfibril hamwe no guhuza imbere imbere.Ibi byitwa uturere twa amorphous ariko byitwa neza dislocations kuva microfibril irimo imiterere yicyiciro kimwe.Agace ka kristalline kari mu bwigunge kugirango gatange microcrystalline selile.
