How to Use Viaduct Blackbox in Manufacturing
Prepare Your Mixing Equipment
Ensure the mixer (ribbon, plough, or high-speed blender) is clean, dry, and free from previous batch residues.
Measure the Required Raw Materials
Weigh cement, fillers, and additives as per the prescribed formulation included in the Blackbox technical sheet.
Open the Blackbox Polymer System
Carefully open the sealed Blackbox and confirm that the material is moisture-free and ready for use.
Add the Polymer to Dry Materials
Introduce the Blackbox polymer into the mixer along with the pre-weighed raw materials in the recommended ratio.
Begin Dry Mixing
Start the mixer and allow the materials to blend uniformly for the time specified in the formulation guide to ensure even dispersion.
Perform Mixing Consistency Check
Stop the mixer briefly and visually inspect texture, colour uniformity, and flow characteristics as per QC guidelines.
Complete the Final Blend
Run the mixer for the remaining prescribed time to achieve a fully homogeneous Tile Adhesive Type 2 powder.
Conduct QC Verification
Check bulk density, mixing density, flow, retention, and basic adhesion benchmarks to ensure the batch meets Type 2 specifications.
