What Effect Can Surface Acid Pickling Achieve on UHPC Panels? Qinglong UHPC Acid Pickling Treatment Technology

Acid pickling treatment on UHPC panel surfaces can expose aggregates, creating a texture similar to natural granite while improving surface wear resistance. With a pickling depth of 0.5-2mm, surface hardness is increased by 15%, and the anti-slip coefficient (BPN) is ≥75, making it suitable for pedestrian flooring, exterior walls, and other applications.

In terms of process control, Qinglong UHPC uses eco-friendly pickling agents (pH 1-2), controlling pickling time to 3-8 minutes, followed by neutralization treatment after water rinsing. After pickling, the surface forms a micro-rough texture with a roughness of Ra=6.3-12.5μm, which is not only aesthetically pleasing but also offers excellent anti-slip performance. A metro station project using acid-pickled UHPC flooring showed only 0.1mm of wear after 3 years of use, demonstrating lasting results.
