Description

Technical Field

[0001] The utility model relates to the field of water reducing agent drying, and more specifically to a drying device for powdered polyhydroxy acid high-impermeability water reducing agent. Background Art

[0002] Polycarboxylic acid high-performance water-reducing agent has a high water-reducing rate and can significantly improve the fluidity of mortar; it can increase the fluidity of grouting material or cement mortar, improve work efficiency, improve plasticity retention ability, increase early and late strength, and prevent or reduce shrinkage cracking after mortar hardening. It can be used exclusively for the production of grouting materials and powder mortar, and is suitable for non-shrinkage grouting materials, cement-based building premixed mortar, cement-based floor mortar, thermal insulation mortar, and waterproof mortar. In the document with publication number CN216558128U, a drying device for powdered polyhydroxy acid high-performance water-reducing agent is proposed. While drying, a stirring rod is used to evenly stir the water-reducing agent, so that the water-reducing agent can be evenly dried to avoid uneven drying.
