Njirimara na iji hydroxyethythythythythyth Cellulose (HEC)

1. Njirimara nke hydroxyethythyth Cellulose
Hydroxyethythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythythyghyyth cellulose) bụ polymen-soluble people na-enwetara site na ngbanwe kemịkal nke sellose. Ihe owuwu ya mejuputara ihe eji eme ihe eji eme ihe eji eme β-1,4-glycosididic. A na-ewebata otu hydroxyethyy (ch2CH9OH2OH) na hydroxyeth molecuse molecuse molecuse, nke jikọta ya na ìgwè hydroxy na mmeghachi omume kemịkal. N'ihi ngbanwe a, hec nwere ọtụtụ ihe dị iche iche site na cellosuo mbụ.
