Cellulose ether- Thickening da Thixotropy
Cellulose etherya ba da rigar turmi tare da ingantacciyar danko, wanda zai iya haɓaka mannewa tsakanin rigar turmi da Layer tushe, haɓaka aikin rigakafin kwararar turmi, kuma ana amfani da shi sosai a cikin plastering turmi, yumbu tile bonding turmi, da tsarin rufin bango na waje.A thickening sakamako na cellulose ether kuma iya ƙara anti watsawa ikon da uniformity na sabo ne kayan, da kuma hana abu stratification, rabuwa, da seepage.Ana iya amfani da shi don simintin ƙarfafa fiber, simintin ruwa na karkashin ruwa, da kuma kankare kanka.
