Cellugul etherE kwesịrị iji mgbanwe ikuku nke ọma na-abawanye ike nke ngwa agha na ahịhịa na-eme ka ọ dị mma, na-eme ka usoro mkpuchi na ngwa agha dị mma. Oditu mmetụta nke cellose ether nwere ike mụbaa otu ihe na ihe mgbochi ciment nke ọhụrụ, iji gbochie stratification, nke a na-agba ya na eriri, mmiri dị n'okpuru mmiri.
Cellugul etherNa-abawanye viscosity nke ihe ndị sitere na ihe ndị dabeere site na viscosity nke sel eat. A na - ejikarị "viscosis" a na - enyocha ihe ngosi Ether, viscosis nke cellulose evether (ọkara) na oke oke (ma ọ bụ na-agbagharị ọsọ, dịka 20) Ọnọdụ RPM), site na ndokwa nke ngwa eji a na-eji a sere, dịka ndị na-ebugharị viccositio n'ụkpụrụ viscositing. Visaitis bụ ihe dị mkpa nke ịtụle arụmọrụ nke celcilose ether, ka ọ dị elu na viser na ihe ndị dị mkpa, Ma ọ bụrụ na viscosity karịrị akarị, nwere ike imetụta ciment ntọala na-agagharị na mgbatị ahụ (dị ka owuwu nke ngwa ngwa ngwa akwa). Ya mere, viscosity nke sel other ejiri ya na ngwa agha a gwakọtara na-abụkarị 15,000 ~ 60,000. S-1, na viscosity nke cellose ether dị ala maka ngwa agha nke onwe ya na kọmputa nke onwe na nke nwere ihe na-akpata ya. Ke adianade do, mmetụta nke cellose eth ga-abawanye mmiri nke ihe ndị sitere na ihe ndị dabeere, site na ịbawanye mmepụta nke ngwa agha. Njeghari nke Ether Ether na-adabere na akwara polymeranzation (ma ọ bụ ogo polymeranzation) na ịta nke cellulose eart, ngwọta okpomọkụ, ọnụego ya, na usoro nnwale. Ogo polymerizations nke cellose eart, ibu oke molecular, onye dị elu na viscosity nke ya; Olu dị elu (ma ọ bụ itinye uche) nke cellulose eart, ndị dị elu na viscosis ya, ma na-a toa ntị na nhọrọ nke usoro onunu ogwu kwesịrị, ka ọ ghara ịgwakọta oke na ihe mgbochi; Dị ka ọtụtụ mmiri, viscosity nke sellulose a ga - agbada na mmụba nke okpomọkụ, na elu ịta akwara mkpụrụ osisi cellose, ka uto nke okpomọkụ; Ngwọta Ethether na-abụkarị anụ pseudoplastic na ala nke shirning.
