What Are the Steps in Producing UHPC Exterior Wall Decorative Lines? Qinglong UHPC Decorative Line Process Explained

The production of UHPC exterior wall decorative profiles involves five key processes: design, mold making, production, curing, and surface treatment. Through refined process control, Qinglong UHPC achieves product precision of ±0.5mm, with surface textures available in a variety of effects such as stone-look, wood-look, and metal-look finishes.

Specific process flow: First, 3D scanning and BIM technology are used for detailed design, optimizing the structure (thickness 15-20mm) and connection joints; then CNC machining of molds (tolerance ≤0.3mm); in the production stage, the spraying process is used (fiber content 5%), along with vacuum dewatering (reducing moisture content to 18%); steam curing (80℃×24h) ensures strength development; finally, surface treatment (sandblasting, acid pickling, coating, etc.). Compared with natural stone, UHPC profiles are 60% lighter (surface density 30kg/㎡), 3 times stronger, allow larger cantilevers (up to 1.5m), and cost 70% less to maintain.

Design Optimization Stage

3D scanning captures precise data; BIM optimizes the structure (thickness 15-20mm); joint design (connector spacing ≤600mm). These optimizations ensure quality.

Mold Making Process

CNC machining (tolerance ≤0.3mm); surface treatment (finish Ra≤3.2μm); these ensure profile precision.

Production Process Control

Spraying process (fiber content 5%); vacuum dewatering (moisture content 18%); these controls guarantee quality.

Surface Treatment Technology

Sandblasting (roughness Ra 6.3-12.5μm); coloring treatment (penetration depth 2-3mm); these techniques enrich the finishes.

Refined craftsmanship ensures product quality. Qinglong UHPC decorative profiles are exquisite and durable, widely acclaimed.
