Hydroxyethyl cellulose ne matsakaici zuwa high danko sa na cellulose ether, amfani da matsayin thickener da stabilizer for ruwa tushen coatings, musamman a lokacin da ajiya danko ne high da aikace-aikace danko ne low. Cellulose ether yana da sauƙin watsawa a cikin ruwan sanyi tare da darajar pH ≤ 7, amma yana da sauƙi don haɓakawa a cikin ruwa na alkaline tare da darajar pH ≥ 7.5, don haka dole ne mu kula da dispersibility na cellulose ether.
Fasaloli da amfani na hydroxyethyl cellulose:
1. Anti-enzyme non-ionic ruwa thickener, wanda za a iya amfani da a fadi da kewayon pH darajar (PH=2-12).
2. Sauƙi don tarwatsawa, ana iya ƙara shi kai tsaye a cikin nau'i na busassun foda ko a cikin nau'i na slurry lokacin da ake niƙa pigments da fillers.
