. These include3. Open Time Extension HPMC increases the open time of tile adhesive, meaning that the adhesive remains workable for an extended period after application. This feature is crucial for large-scale projects or intricate tiling patterns where precise placement and adjustments are necessary before setting the tiles.
The degree of substitution of hydroxyethyl groups along the cellulose chain significantly affects the solubility of HEC. Higher degrees of substitution generally lead to an increased solubility due to a greater number of hydrophilic sites, enhancing the interaction with water. However, there is a balance; excessively high substitution levels may lead to instability and a decrease in performance due to increased viscosity.
When the dry mortar is added to the water and stirred, the rubber powder particles are dispersed into the water under the action of the hydrophilic protective colloid and mechanical shearing force. The time required for the dispersion of the normal dispersible polymer powder is very shot. For example, in the dry-sprayed concrete repair mortar, the dry mortar with Redispersible Polymer Powder and the water are sprayed only at the end of the nozzle for about 0.1s. To the construction surface, this is sufficient to fully disperse and film the redispersible powder.
