1 Mmiri mmiri

Cellulose ether nwere mmetụta dị ukwuu na njide mmiri, nkwụsi ike na ịrụ ọrụ nke ngwa agha.Karịsịa dị ka ngwa agha na-edozi onwe ya, mmiri mmiri bụ otu n'ime isi ihe na-egosi iji nyochaa arụmọrụ nke onwe.Enwere ike ịhazigharị mmiri nke ngwa agha site na ịgbanwe ọnụọgụ cellulose ether n'okpuru ebe a na-ahụ maka nhazi nkịtị nke ngwa agha.Ọdịnaya dị elu ga-ebelata mmiri mmiri nke ngwa agha, ya mere, ekwesịrị ịchịkwa ọnụọgụ cellulose ether n'ime oke ezi uche.
