1. Hydration at Swelling Ang unang hakbang sa mekanismo ng pagpapalapot ng HEC ay ang hydration. Kapag ang HEC ay nilagay sa tubig, ang mga hydroxyl group (–OH) sa mga molekula nito ay nakikipag-ugnayan sa mga molekula ng tubig. Ito ay nagiging sanhi ng pagsipsip ng tubig at pagbubuo ng isang gel-like na estruktura. Ang prosesong ito ay nagpapalaki sa laki ng mga HEC particles, na nagreresulta sa pagtaas ng viscosidad ng solusyon.

Factors Influencing Solubility
Once the raw materials are selected, the next step is emulsion polymerization. In this process, the selected monomers are dispersed in water with the help of surfactants. The mixture is then subjected to heat and initiators, which catalyze the polymerization reaction. As the reaction progresses, polymer chains begin to form, resulting in a stable emulsion of fine polymer particles suspended in water. The stability of this emulsion is critical, as it ensures that the powder can be redispersed effectively later on.
Another advantage of HPMC is its resistance to sagging. When tiles are applied to walls or ceilings, it is essential that the adhesive holds the tiles in place without slipping. HPMC-enhanced tile adhesives have a thixotropic nature, which means they can maintain their shape under gravitational forces, providing a stable hold for tiles during the installation process. This characteristic not only enhances safety but also improves the overall aesthetic of the finished project.
