What Role Does Cellulose Ether For Coating Play in Dry-mix Mortar?

In dry-mix mortar, cellulose ether plays the role of water retention, thickening and thixotropy, air entrainment, and slow setting. Good water retention makes cement hydration more complete, which can improve the wet viscosity of wet mortar, increase the bonding strength of mortar, and increase the open time and adjustment time in tile bonding mortar. Adding cellulose ether to mechanical spray mortar can improve the structural strength of mortar. It can prevent sedimentation, segregation and stratification in self-leveling. Therefore, cellulose ether is being widely used as an important additive in dry-mix mortar. In order to give full play to the application of cellulose ether in dry-mix mortar, it is also crucial to choose the type of cellulose ether and determine its application range.
