1. How to Use Gypsum Retarder?
Mix the gypsum retarder evenly with dry gypsum powder before adding water. Ensure thorough blending for uniform retardation. In industrial production, it can be added directly into the dry-mix process or the slurry preparation stage, depending on the production setup.
2. What Is the Recommended Dosage of the Gypsum Retarder?
The optimal dosage typically ranges from 0.05% to 0.3% of the total gypsum weight, depending on the raw material type, temperature, and desired setting time. It’s recommended to conduct small-scale testing to determine the best dosage for specific formulations.
3. How to Slow Down the Setting of Gypsum?
To extend gypsum setting time, use a high-performance gypsum retarder such as the Think-Do HN Series. Adjust the dosage gradually while maintaining proper mixing and temperature control. Avoid adding excessive water, as it may weaken the final strength and surface quality.
