What Steps Does the UHPC Exterior Wall Decorative Line Production Process Include — Detailed Analysis and Key Step Guide

In the field of contemporary architectural decoration, UHPC exterior wall decorative lines are becoming the "finishing touch" of high-end building facade design thanks to their outstanding mechanical properties and artistic expressiveness. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical advantages to systematically explain the standardized manufacturing process of UHPC exterior wall decorative lines, revealing how to give concrete a "sculpture-grade" texture.

I. UHPC Material Properties and Process Prerequisites: Precision Control from Formulation to Design

As a third-generation cement-based composite material, UHPC (Ultra-High Performance Concrete) has a manufacturing process whose core lies in deeply matching material properties with design requirements. Before production, Qinglong Group optimizes the material mix ratio (steel fiber content of 1.5–2%, silica fume replacing 15–20% of cement), pushing the material's compressive strength beyond 150MPa and flexural strength above 25MPa, ensuring that decorative lines combine slim, lightweight characteristics (thickness down to 30mm) with structural safety. During the detailed design stage, BIM technology and parametric modeling (such as Rhino+Grasshopper) are used to convert architectural drawings into producible component models, while reserving installation nodes and shrinkage joints to avoid later cracking risks.

II. Five Key Processes in UHPC Decorative Line Manufacturing: Qinglong's Full-Process Quality Control Standards

1. Mold Preparation: The Foundation for Replicating Design Precision
High-precision steel molds or fiberglass molds (GRP material) are used, with mold surfaces polished to a mirror finish to ensure the smoothness of the line surfaces. Qinglong Group's independently developed mold temperature control system keeps the temperature difference of the pouring environment within ±2°C, avoiding surface defects caused by thermal stress.

2. Material Mixing and Pouring: Homogeneity as the Guarantee of Performance
A double-shaft compulsory mixer is used, with strict control of the water-binder ratio (0.18–0.22) and mixing time (≥5 minutes) to ensure uniform dispersion of steel fibers. During pouring, vacuum-assisted molding technology removes air bubbles; for complex-shaped components, layered pouring and vibration techniques are applied to ensure density.

3. Curing Process: Key Enhancement of Strength and Durability
A combined "steam curing + natural curing" process is adopted: within 24 hours after pouring, 90°C steam curing accelerates the hydration reaction; the material then undergoes 28 days of natural curing for steady strength growth. Qinglong's dedicated curing kilns enable precise control of humidity above 95% and a temperature gradient of ≤5°C/h, preventing surface carbonation.

4. Surface Treatment: The Transformation from Industrial Component to Artwork
Different texture requirements are achieved through sandblasting, acid washing, or manual polishing; antique-style lines use a special coloring process with color uniformity deviation controlled at ΔE≤3. Qinglong's original nano-scale protective coating technology gives the lines a self-cleaning function and improves weather resistance by more than 50%.

5. Quality Inspection and Installation Adaptation: Full Life-Cycle Assurance
Each batch of products must pass 12 tests covering flexural strength, elastic modulus, freeze-thaw cycles (200 cycles) and other indicators. Before installation, 3D scanning and trial assembly are performed with errors controlled within ±2mm, and the accompanying stainless steel connector system accommodates an installation adjustment range of ±30mm, ensuring on-site construction precision.
