Can UHPC Shape Colors Achieve Gradient Effects? Qinglong Gradient Technology and Color Assurance

The color of UHPC shapes can fully achieve gradient effects. Through three core technologies—"integral coloring, coating gradients, and mold zoning"—diverse effects such as single-color gradients, multi-color gradients, and partial gradients can be realized. With its inorganic pigment formulation and precise process control, Qinglong Group achieves natural and smooth gradient transitions with a color difference of ΔE≤2.0. Projects such as Hainan Poly Peninsula No. 1 and the Nanning Liyuan Hotel have verified its technical strength.

1. Integral Coloring Gradient: Deep Penetration, Long-lasting Stability

Layered pigment addition: During production, different colored inorganic pigments are added in layers into the UHPC mix according to the designed gradient ratio, and dual-shaft mixing achieves natural color blending. The ocean blue gradient shapes of Qinglong's Hainan Poly Peninsula No. 1 transition naturally from light blue to dark blue with no obvious dividing lines. Gradient placing process: A multi-compartment placing machine feeds material sequentially in gradient order, with placing speed (0.5-1m/min) coordinated with mixing speed to ensure uniform gradients. The red-orange gradient decorative panels of a Qinglong commercial complex achieved smooth transitions through gradient placing, with gradient lengths ≥3m. Advantages and applicable scenarios: Color penetration depth ≥5mm, wear-resistant and UV-resistant, fading rate ≤2%/10 years, suitable for large outdoor shapes; Qinglong's Hainan project gradient shapes have been in use for 5 years with no degradation in gradient effect.

2. Coating Gradient: Flexible and Controllable, Adaptable to Complex Shapes

Base color + gradient coating: First the UHPC base color (single color) is produced, then a gradient coating (fluorocarbon paint, real stone paint) is applied by spraying or brushing, with a coating thickness of 30-50μm. The colored carved pattern gradient at Qinglong's Nanning Liyuan Hotel uses a white base color with a coating achieving a pink-purple gradient, with exquisite details. Mask spraying technology: Hollow-out masks are used to control gradient areas, and transitions in color depth are achieved by adjusting spray gun distance (20-30cm) and spraying pressure (0.3-0.5MPa). A Qinglong art sculpture using mask spraying achieved precise partial gradient effects with clear boundaries. Advantages and applicable scenarios: Flexible color adjustment, capable of partial gradients, adaptable to complex carved and hollow-out shapes; the partial gradient on light-transmitting panels at Qinglong's Shanghai New World echoes the light and shadow effects.

3. Mold Zoning Gradient: Precise Zone Control, Multi-color Coordination

Mold zoning design: The mold is divided according to gradient areas, with each area pre-coated with the corresponding color pigment or fitted with color paste strips; after UHPC casting, the colors naturally diffuse into gradients. A Qinglong municipal landscape shape used a mold divided into 3 areas, achieving a green-yellow-orange three-color gradient with natural transitions. Color paste penetration control: Special inorganic color pastes are selected, with concentration (50%-70%) matched to casting speed (0.2-0.3m³/h) to ensure consistent color penetration depth; the color penetration depth of Qinglong's mold zoning gradients is ≥3mm, with uniform gradients. Advantages and applicable scenarios: Excellent multi-color gradient effects, adaptable to regular geometric shapes; the UHPC gradient parquet flooring at a Qinglong plaza achieved a four-color gradient through mold zoning, with high aesthetic appeal.

4. Qinglong's Durability Assurance and Project Verification for Gradient Effects

Durability assurance: Inorganic pigments are used (weather resistance ≥1000h xenon lamp aging), and gradient areas are coated with fluorocarbon coatings (thickness ≥35μm) for UV and rain erosion resistance; Qinglong's gradient shapes have a 10-year fading rate ≤2% and color retention ≥90%. Project verification: Hainan Poly Peninsula No. 1 (ocean blue integral gradient) has been used outdoors for 5 years with seamless gradient transitions and a fading rate of 1.2%; the Nanning Liyuan Hotel (pink-purple coating gradient) has been used indoors for 8 years with the gradient effect still intact; a municipal landscape (green-yellow-orange mold zoning gradient) has been used outdoors for 6 years with no color bleeding or fading. Technical advantages: Natural gradient transitions (ΔE≤2.0), customizable colors (full Pantone color card coverage), adaptable to different shapes (flat, curved, hollow-out), and strong durability.

The gradient effects of UHPC shapes are achieved through diverse technologies, with the core being pigment selection, process control, and mold adaptation. With its gradient technology strength and durability assurance, Qinglong Group makes UHPC shapes richer in color and more artistic. Choosing a manufacturer with gradient technology capability is key to realizing color creativity in UHPC shapes.
