1. Thickening Effect: HPMC possesses long molecular chains capable of forming a three-dimensional network structure within water, thereby increasing the viscosity of the mortar. This facilitates easier handling during transportation and construction, effectively prevents water evaporation, and enhances the mortar’s workability.
2. Water Retention Effect: HPMC exhibits excellent water-retention properties, effectively delaying the setting time of the mortar. This minimizes the occurrence of drying shrinkage cracks during transportation and application, thereby improving the mortar’s overall durability.
3. Suspension Effect: HPMC provides effective suspension capabilities, preventing the aggregates within the mortar from settling. This ensures that the mortar remains free from segregation during use, thereby maintaining its structural uniformity.
4. Bonding Effect: HPMC demonstrates strong bonding capabilities, enhancing the adhesion between the mortar and the substrate. This prevents the mortar from detaching during construction, thereby improving its overall adhesion strength.
5. Film-Forming Effect: The film formed by HPMC possesses excellent toughness and durability, which serves to enhance both the waterproofing performance and the long-term durability of the mortar.
