Can UHPC Shapes Achieve Color Gradient Effects? Research on UHPC Color Gradient Technology

UHPC sculptural color gradients are achieved through three technologies: layered casting, surface coloring, and digital printing. Layered casting achieves macro gradients (transition length ≥300mm), surface coloring is suitable for meso gradients (transition length 50-100mm), and digital printing realizes micro gradients (transition length ≤10mm). Color stability of ΔE≤3.0 (1000 hours of UV aging) meets long-term service requirements.

Specific process control: the time interval between layered casting passes must not exceed the initial setting time, with color slurry dosage error ≤1%; surface coloring uses dedicated equipment with spray coating thickness uniformity ≥90%; digital printing resolution ≥600dpi with color reproduction ≥95%. An art wall featuring gradient colors shows natural, smooth transitions, with colors remaining in good condition after 3 years of use. The color database established by Qinglong UHPC contains more than 1,000 color formulas, enabling precise realization of design effects.

Layered Casting Technology

The time interval between layer casting is controlled to ≤45 minutes to ensure interlayer bonding. Color slurry dosage is precisely controlled with error ≤0.5%. Color transition samples are established to guide on-site construction.

Surface Coloring Process

CNC spraying equipment is used with trajectory precision ≤1mm. Coating thickness is 30-50μm with uniformity ≥90%. Thorough surface pretreatment ensures coloring quality.

Digital Printing Technology

Dedicated UV inks are used with weather resistance of ≥10 years. Printing resolution ≥600dpi with color reproduction ≥95%. Surface coating protection improves durability.

Color Stability Control

Inorganic pigments are used with light resistance ≥ Grade 7. Accelerated aging tests show ΔE≤3.0. Regular maintenance keeps colors vivid.

Color gradients enhance artistic expression. Through precise process control, design creativity and durability are unified.
