Technical Strength of Manufacturers Capable of Producing Colored UHPC — Qinglong's UHPC Color Technology Advantages

Colored UHPC production technology includes three processes: integral coloring, surface coloring, and composite coloring. Premium manufacturers can achieve color stability of ΔE≤3.0 and weather resistance of ≥20 years. Qinglong UHPC adopts matrix coloring + surface protection technology, achieving color stability of ΔE≤2.0 and long-lasting aesthetics without fading for 50 years.

Technical implementation: inorganic mineral pigments (lightfastness grade 8), through-body coloring depth ≥10mm, and fluorocarbon coating (thickness ≥35μm) protection. The colored UHPC curtain wall of a cultural center project showed a color difference of ΔE=1.2 after 5 years of use, with its color remaining as vibrant as new. The Qinglong UHPC color database contains over 1,000 standard colors and supports custom color matching.

Coloring Process Comparison

Integral coloring: consistent color throughout with good wear resistance; surface coloring: vivid colors at lower cost; composite coloring: combines the advantages of both for the best results. Choose the appropriate process based on the application area.

Color Stability Control

Pigment lightfastness ≥ grade 7 and weather resistance ≥ grade 5; pigment dosage of 3%-5%, uniformly dispersed; optimized curing regime to avoid color changes; protective treatment to improve color retention. Color stability control is the technical key.

Color Consistency Assurance

Raw material batch stability control; precise mix proportion measurement; stable production process parameters; online color monitoring and adjustment. Full-process control ensures batch-to-batch consistency.

Achieving Special Effects

Stone-like texture is achieved through aggregate exposure; metallic effects through metallic pigments; pearlescent effects through mica pigments; gradient effects through layered casting. Special effects enhance decorative appeal.

Rich colors open up design possibilities. Qinglong UHPC's advanced technology brings creative visions to life.
