Can UHPC Shaped Elements Achieve Gradient Color Effects? Qinglong's Multi-Gradient Process and Color Control Solution

The color of UHPC shapes can fully achieve gradient effects. Through three core processes—integral coloring, surface coating, and module splicing—you can create diverse effects such as single-color transitions, multi-color gradients, and texture gradients to meet artistic and creative needs. With 28 years of color R&D experience, Qinglong Group has delivered UHPC shapes with natural gradient transitions and stable colors in projects such as Hainan Poly Peninsula No.1 and Shanghai New World, with a 10-year fading rate of ≤2%, far exceeding the industry average.

I. Integral Coloring Gradient: Full-Body Penetration, Long-Lasting and Stable

Core process: During the UHPC batching stage, inorganic mineral pigments are added in layers according to preset proportions, with gradient dosages achieving natural color transitions. The pigments fully integrate with the base material, giving uniform color throughout the body with no risk of surface peeling. Qinglong's integral coloring uses highly weather-resistant inorganic pigments with dosage precisely controlled at 5%-8%, and a gradient transition width of ≥50mm. Application scenarios: small and medium-sized artistic sculptures and decorative lines. The Hainan Poly Peninsula No.1 UHPC specially-shaped double-curved panel project used this process to create an ocean-blue gradient effect that blends perfectly with the seascape environment. Technical points: a twin-shaft forced mixer is used with mixing time extended to 4-5 minutes to ensure uniform pigment distribution. Qinglong's integral coloring gradient has a color difference of ΔE≤1.5, with natural transitions and no visible breakpoints.

II. Surface Coating Gradient: Fine Transitions, Flexible Adjustment

Core process: Gradient coatings are applied to the surface of UHPC shapes through spraying and brushing processes, achieving fine color transitions. The coating thickness is 30-50μm, with fluorocarbon paint used to enhance weather resistance and gloss. Qinglong's surface coating uses imported fluorocarbon resin with excellent UV aging resistance. Application scenarios: large curtain wall panels and commercial space decorative shapes. The Shanghai New World UHPC wood-grain translucent panel project achieved a brown-to-white gradient through surface coating, paired with wood grain textures for a realistic look and feel. Technical points: intelligent spraying equipment controls spray pressure (0.3-0.5MPa) and gun travel speed to ensure uniform coating thickness. Qinglong's surface coating gradient transitions smoothly with no obvious color difference boundaries.

III. Module Splicing Gradient: Large-Scale Shapes, Precise and Controllable

Core process: UHPC modules of different colors are spliced in gradient sequence, with module color deviation ≤ΔE2.0 and splicing gaps ≤±0.5mm. Sealant filling and finishing achieves the overall gradient effect. Qinglong's module splicing uses BIM modeling to optimize layout, ensuring precise color transitions. Application scenarios: exterior walls of large landmark buildings and landscape corridors. The Nanning Wuxiang China Resources MixC One UHPC curtain wall project achieved a rainbow gradient through module splicing with strong visual impact. Technical points: module production uses unified molds and processes with color consistency reaching 98%, and color-matched sealant is used at splicing points. Qinglong's module splicing gradient delivers a coordinated overall effect with no obvious splicing marks.

IV. Qinglong's Gradient Process Advantages and Color Control Technology

Precise color simulation: Gradient effects are simulated using software such as Photoshop and Rhino, generating detailed color parameter tables to guide production. The color difference between Qinglong's color simulations and actual finished products is ΔE≤2.0, with a reproduction rate of 95%. Weather resistance assurance: UV inhibitors and anti-aging agents are added; after 1000h xenon lamp aging tests, color retention is ≥90%. Qinglong's gradient UHPC shapes have a 10-year fading rate of ≤2%, suitable for long-term outdoor use. Strong customization capability: Any gradient effect can be customized according to customer needs—from single-color transitions to multi-color gradients, from linear gradients to circular gradients—all precisely achievable. Qinglong completes over 50 customized gradient schemes annually on average.

V. Project Evidence and Application Recommendations

Project evidence: The ocean-blue gradient UHPC panels at Hainan Poly Peninsula No.1 show no obvious color degradation after 5 years of use; the brown-white gradient translucent panels at Shanghai New World remain intact in gradient effect despite sun and rain exposure; the rainbow gradient curtain wall at Nanning Wuxiang China Resources MixC One has become a city commercial landmark. Application recommendations: Outdoor projects should prioritize integral coloring or fluorocarbon coating gradients to enhance weather resistance; indoor projects can choose surface coating gradients to reduce costs; module splicing gradients are recommended for large-scale shapes, balancing precision and efficiency.

The color gradient effects of UHPC shapes can be achieved through various processes. With precise color control, advanced production processes, and strict quality inspection, Qinglong Group creates high-quality gradient works. Choosing a manufacturer with core color gradient capabilities is key to achieving creative expression in UHPC artistic shapes.
