  • One of the key advantages of redispersible polymer powders is their ability to improve the performance of cementitious composites. When these powders are added to concrete or mortar, they form a film around the cement particles, reducing their surface tension and improving their dispersion. This results in a more uniform distribution of cement throughout the mixture, leading to improved strength and durability. Additionally, the films formed by the redispersible polymer powders help to reduce water evaporation, which can lead to faster setting times and reduced cracking.
  • Firstly, it is crucial to understand that HPMC is generally recognized as safe for use in food, pharmaceuticals, and cosmetics by regulatory bodies such as the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). Despite this recognition, proper handling and usage guidelines must still be adhered to.
  • The synthesis of HEC involves the substitution of hydroxyl groups in cellulose with hydroxyethyl groups. The most common method for synthesizing HEC is the alkali hydrolysis of cellulose followed by ethoxylation. In this process, cellulose is treated with sodium hydroxide to disrupt its crystalline structure, making it more susceptible to chemical modification. The resulting alkali cellulose is then reacted with ethylene oxide in the presence of a catalyst to introduce hydroxyethyl groups. The degree of substitution (DS), which refers to the average number of hydroxyethyl groups per glucose unit in HEC, can be controlled by adjusting the reaction conditions.
