Commonly used in thermal insulation mortars are hydroxypropyl methylcellulose (HPMC), methyl hydroxyethyl (MHEC), redispersible latex powder (RDP), etc.
Main function
▶ Water retention: Cellulose ether has good water retention performance, which can effectively prevent the mortar from evaporating too quickly during the drying process, thereby maintaining the wetness of the mortar, which is conducive to the hardening and strength of the mortar.
▶ Adhesion: Cellulose ether can enhance the adhesion of the mortar, make the mortar better adhere to the base material, and improve the overall stability of the thermal insulation system.
▶ Anti-sagging: Cellulose ether can improve the anti-sagging of the mortar, prevent the mortar from flowing or sagging during the application or construction process, and ensure the construction quality.
▶ Thickening: After dissolving, cellulose ether forms a polymer film in water, which increases the viscosity of the slurry, makes the mortar denser, and is conducive to construction operations.
▶ Air entrainment: Cellulose ether also has a certain air entrainment effect. A small amount of small bubbles are introduced through stirring, which will play a role similar to "ball bearings", increase the uniformity of the slurry, and improve the workability of the mortar.
