Isi Atụmatụ:
A na-ejikarị eriri ether na-ejikarị ya na njikọta methy cellulose ether, nke na-egosi mmetụta dị mma n'etiti abụọ. Na-agbakwunye ego nke starch eat to methy cellulose eather nwere ike ime ka nguzogide ndagide na ngọngọ nke ngwa agha, ya na nguzogide nke ngwa agha, ya na ngọngọ.
(2) na-agbakwunye ọnụego Starch EET na ngwa agha na Mether nwere ike ịbawanye na-agbanwe agbanwe nke ngwa agha ma melite ọnya ahụ, na-eme ka owuwe ihe dị nro na ihe ọ scraping.
(3) ịgbakwunye ego kwesịrị ekwesị na ngwa agha nke nwere methy cellulose ether nwere ike iwepụta mmiri iji nweta mmiri nke ngwa agha ma mee ka oge gboo a na-emeghe.
