Focus on Cellulose ethers

Koodu nhazi ọkwa cellulose ether na teknụzụ chọrọ

Cellulose bụ ihe akụrụngwa nwere ike imeghari n'ụwa kachasị ukwuu. Ọ na-abịa site na akwụkwọ ndụ akwụkwọ ndụ terrestrial na okpuru mmiri okpuru mmiri na bụ isi akụkụ nke osisi fiber cell mgbidi. Ewezuga obere nje bacteria anụmanụ na ihe ndị dị n'oké osimiri, cellulose na-adịkarị na osisi ndụ ndụ. Site photosynthesis, osisi nwere ike synthesize 155Gt cellulose kwa afọ, nke 150Mt si elu osisi; cellulose pulp osisi bụ ihe dịka 10Mt; cellulose owu 12Mt; chemical (grade) 7Mt nke cellulose, ebe nnukwu osisi (ihe dịka 500Mt cellulose) ka na-eji dị ka mmanụ ụgbọala ma ọ bụ akwa akwa.
cellulose eke dị iche iche na ịdị ọcha. Owu bụ eriri osisi nwere ọdịnaya cellulose kachasị elu na okike, ọdịnaya cellulose ya na-adịkarị karịa 95%. A na-eji ihe eji eme akwa akwa ogologo owu. A na-akpọ eriri dị mkpirikpi nke Linter pulp, nke bụ ihe dị mkpa maka mmepụta nke mmepụta cellulose.
