What Are the Surface Decoration Treatment Methods for UHPC Exterior Wall Panels? A Complete Guide to Qinglong UHPC Surface Treatment Technologies

The surface decoration treatment technologies for UHPC facade panels mainly include five major categories: polishing treatment (roughness Ra≤0.8μm), sandblasting treatment (roughness Ra=3.2-12.5μm), acid pickling treatment (forming a stone-like texture), fluorocarbon spraying (coating thickness≥35μm), and stone-imitation coatings (simulation degree≥95%). Through different surface treatment processes, UHPC can achieve a variety of decorative effects ranging from mirror smoothness to rugged stone grain, meeting the needs of different architectural styles.

Qinglong UHPC adopts advanced CNC surface treatment equipment to ensure treatment precision and consistency. Among them, mechanical polishing can achieve a surface finish of over 90°, suitable for modern minimalist styles; sandblasting treatment can create a uniform textured surface with good slip resistance; acid pickling treatment can expose aggregates to form a natural stone texture. A high-end commercial project adopted stone-imitation treated UHPC panels that were hard to distinguish from natural stone, while reducing cost by 40% and weight by 60%.

Polishing Treatment Technical Indicators

Surface roughness Ra≤0.8μm; gloss≥90GU; these indicators achieve a mirror effect.

Sandblasting Treatment Process Parameters

Emery grit size 80-120 mesh; jetting pressure 0.4-0.6MPa; these parameters control the texture.

Acid Pickling Treatment Key Points

Acid pickling concentration 3%-5%; duration 5-8 minutes; these key points affect the effect.

Coating Treatment Performance Requirements

Fluorocarbon coating weather resistance≥20 years; these requirements ensure durability.

Surface treatment determines the aesthetic effect. Qinglong UHPC offers multiple processes to meet personalized needs.
