The higher the viscosity, the more obvious the thickening effect of the mortar, but it is not proportional. The higher the viscosity. The more sticky the wet mortar will be. During construction. It will stick to the scraper and have high adhesion to the substrate. But it does little to increase the structural strength of
For the same product, the viscosity results measured by different methods are very different, and some even double the difference. Therefore, when comparing viscosity, be sure to do it between the same test methods, including temperature, rotor, etc. For particle size, the finer the particle, the better the water retention. After the large particles of
The Chinese name of HPMC is hydroxypropyl methylcellulose, which is non-ionic. It is often used as a water-retaining agent in dry-mixed mortar and is the most commonly used water-retaining material in mortar. The production process of HPMC is mainly a polysaccharide ether product produced by alkalization and etherification of cotton fiber (domestic). It has no
