How Do Large UHPC Panels Achieve a Continuous Stone Vein Effect on the Surface? Qinglong UHPC Stone Vein Effect Production Technology

The continuous stone-grain effect on the surface of large UHPC panels is achieved through CNC-engraved molds, multi-layer coloring technology, and surface treatment processes. A five-axis CNC engraving machine engraves stone textures onto the mold (depth 0.5-3mm); through the dual process of through-body coloring plus surface coloring, followed by stone-imitation treatment, the stone-grain effect runs through the panel thickness, leaving no exposed base after wear.

In the specific process, Qinglong UHPC has developed specialized technologies: mold engraving precision of 0.1mm perfectly replicates natural stone textures; through-body coloring with inorganic mineral pigments (dosage 3%-5%) ensures lasting color; the surface is treated with stone-imitation coating to achieve realistic texture restoration. In a commercial complex project, the largest panel size reached 6m×3m, with natural and smooth stone-grain joints and color difference ΔE≤2.0, achieving an effect indistinguishable from real stone.

Mold Engraving Technology

Five-axis CNC engraving, precision 0.1mm; texture depth 0.5-3mm; these technologies precisely replicate stone grain.

Coloring Process Control

Through-body coloring with pigment dosage 3%-5%; surface coloring with strong layering; these processes ensure lasting color.

Surface Treatment Technology

Stone-imitation coating with realistic texture; wear-resistant treatment for long service life; these technologies enhance the effect.

Joint Effect Control

Texture alignment error ≤1mm; color difference ΔE≤2.0; these controls ensure overall integrity.

The stone-grain effect requires comprehensive technology. Qinglong UHPC's proprietary processes deliver a realistic and durable effect.
