In dry mixed mortar products, due to the addition of cellulose ether(HPMC/ Hydroxypropyl Methylcellulose), a certain amount of small, uniform and stable air bubbles will be introduced into the fresh plastering mortar. Due to the bubble ball effect, the mortar has good construction properties- reduce the shrinkage of mortar and crack and improve the output rate of mortar. Depending on the strength and consistency of.. read more →

Properties of Cellulose Ether in Mortar

0 Comment

The most important characteristic of cellulose ether (Hydroxypropyl Methylcellulose(HPMC) is its water retaining capacity in building materials. As water also plays a role of lubrication and mixing in the inorganic composition, sufficient moisture can meet the requirement of construction. Thus thin layer of sand mortar can be easy to card or repeatedly plaster to be leveled. In addition, due.. read more →

Anti-dispersion is an important technical indicator to measure the quality of anti-dispersion agents. Hydroxypropyl Methylcellulose(HPMC) is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer, which can increase the viscosity of mixed water by increasing the consistency of the mixture. It is a hydrophilic polymer substance that can form a solution or dispersion after dissolving.. read more →

The Water Retention Functions and Principles of Hydroxypropyl Methylcellulose The HPMC mainly plays a role in water retention and thickening, able to effectively improve the bond force and sag resistance of slurry. Air temperature, humidity, wind pressure and other factors will affect the evaporation rate of water in cement mortar and gypsum-based products. Therefore, in.. read more →
