  Redispersible polymer powders are white, free-flowing powders produced by spray-drying polymer dispersions. When these polymer powders are mixed with water, they can re-disperse and form polymer dispersions with the same properties as the original dispersion.   Redispersible polymer powders are added to mortar to increase the flexibility and cohesiveness of mortar. This forms a continuous polymer film that helps improve water retention, enhance the bond strength of mortar, and improve the workability of dry mix mortar.   Production Process of Redispersible Polymer Powder (RDP) Redispersible polymer powder  is produced from latex emulsions through a process of spray-drying macromolecular dispersions under specific conditions. To prevent the latex particles from bonding together during production, polyvinyl alcohol is added. These polymer powders are typically based on acrylic polymers, polyvinyl acetate, copolymers of vinyl acetate with vinyl versatate, or with ethylene.   RDPs consis

  Hydroxyethyl Cellulose: A Versatile Chemical Compound   Hydroxyethyl Cellulose  is a white, free-flowing granular powder derived from alkali cellulose and ethylene oxide (or ethylene chlorohydrin) through etherification. It belongs to the category of non-ionic soluble cellulose ethers, soluble in both hot and cold water.   This compound boasts an array of beneficial properties, including excellent thickening, suspending, dispersing, emulsifying, film-forming, and water-protecting capabilities. It also serves as a protective colloid. Due to these qualities, Hydroxyethyl Cellulose finds extensive applications across various industries such as oil exploitation, coating, building, medicine, food, textile, papermaking, and polymerization.   In the realm of daily chemical products like toothpaste, soap, lotion, cosmetics, and ointments, Hydroxyethyl Cellulose plays crucial roles as a thickener, dispersing agent, binder, and stabilizer. It enhances product density, lubrication, and merceriz
