Can UHPC Shapes Achieve Gradient Color Effects? Qinglong's Multi-Gradient Process and Color Control Solutions

UHPC shapes can fully achieve gradient color effects. Through three core processes—integral coloring, surface coating, and module splicing—it is possible to create diverse effects such as single-color transitions, multi-color gradients, and texture gradients, meeting 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.

1. Integral Coloring Gradient: Full-Body Penetration, Long-Lasting Stability

Core process: During the UHPC batching stage, inorganic mineral pigments are added in layers according to preset proportions, achieving natural color transitions through gradient dosing. The pigments fully blend with the base material, resulting in 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. In the Hainan Poly Peninsula No. 1 UHPC double-curved panel project, this process created an ocean blue gradient effect that blends perfectly with the seaside environment. Key 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 abrupt breaks.

2. Surface Coating Gradient: Fine Transitions, Flexible Adjustment

Core process: By applying gradient coatings on the surface of UHPC shapes through spraying and brushing processes, fine color transitions can be achieved. The coating thickness is 30-50μm, and fluorocarbon paint is 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. In the Shanghai New World UHPC wood-grain translucent panel project, a brown-to-white gradient was achieved through surface coating, combined with wood grain textures for a realistic finish. Key technical points: intelligent spraying equipment is used to control spraying pressure (0.3-0.5MPa) and gun travel speed, ensuring uniform coating thickness. Qinglong's surface coating gradient transitions smoothly, with no obvious color difference boundaries.

3. Module Splicing Gradient: Large Shapes, Precise and Controllable

Core process: UHPC modules of different colors are spliced in gradient sequence, with module color deviation of ≤ΔE2.0 and splicing gaps of ≤±0.5mm. The overall gradient effect is achieved through sealant filling and finishing. 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. In the Nanning Wuxiang China Resources MixC One UHPC curtain wall project, a rainbow gradient was achieved through module splicing, creating strong visual impact. Key technical points: module production uses unified molds and processes, achieving 98% color consistency, and matching-color sealant is applied at splicing joints. Qinglong's module splicing gradient presents a coordinated overall effect with no obvious splicing traces.

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

Precise color simulation: Gradient effects are simulated using software such as Photoshop and Rhino to generate detailed color parameter tables that 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 a 1000h xenon lamp aging test, the color retention rate is ≥90%. Qinglong's gradient UHPC shapes have a 10-year fading rate of ≤2%, suitable for long-term outdoor use. Strong customization capabilities: 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 solutions annually on average.

5. Project Evidence and Application Recommendations

Project evidence: The ocean blue gradient UHPC panels at Hainan Poly Peninsula No. 1 have shown no obvious color fading after 5 years of use; the brown-white gradient translucent panels at Shanghai New World remain intact in gradient effect despite sun exposure and rain; the rainbow gradient curtain wall at Nanning Wuxiang China Resources MixC One has become an urban commercial landmark. Application recommendations: For outdoor projects, 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 shapes, balancing precision and efficiency.

The color gradient effects of UHPC shapes can be achieved through multiple processes. With precise color control, advanced production technology, 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.
