UHPC Production Process Precision Control System — Qinglong's UHPC Manufacturing Technology Advantages

The UHPC production process comprises four key steps: precise raw material metering (error ≤0.5%), efficient mixing (3-5min), precision forming and casting, and scientific curing and hardening (temperature 20±2°C). High-quality UHPC production requires batching accuracy of ±0.5%, mixing uniformity ≥95%, and precisely controlled curing regimes. Qinglong UHPC has introduced fully automated German production lines, achieving batching accuracy of ±0.1%, mixing uniformity ≥98%, and a first-pass product qualification rate ≥99%.

Precise control of process parameters: loss-in-weight scale metering system with 0.1% accuracy; twin-shaft forced mixer at 45-50rpm; vacuum dewatering process at -0.08 to -0.1MPa; steam curing regime of 80°C×24h with heating rate ≤10°C/h. After a new production line was commissioned, the product strength dispersion coefficient dropped from 8% to 3%, with quality stability leading the industry.

Batching and Metering Process

Electronic scales with 0.1% accuracy, regularly calibrated and verified; optimized feeding sequence, dry materials first then liquid materials; fibers added in batches to avoid clumping; complete recording system for full traceability. Precise metering is the foundation of quality.

Mixing Technology

Forced mixer with precisely adjustable speed; mixing time of 3-5min to ensure uniform blending; real-time consistency monitoring with timely ratio adjustments; uniformity testing at discharge as the first quality checkpoint. Uniform mixing is the key step.

Forming Process Control

Casting drop height controlled ≤1m to avoid material segregation; layered casting thickness ≤300mm to ensure compactness; proper vibration techniques to remove internal air bubbles; fine surface treatment to ensure appearance quality. Careful forming guarantees quality.

Curing Regime Optimization

Resting period of 1-2h to prevent plastic cracking; scientific steam curing regime to promote strength development; heating rate ≤10°C/h to prevent thermal stress; humidity control ≥90% to ensure full hydration. Scientific curing determines final performance.

Advanced processes create outstanding products. Qinglong UHPC's precision control system ensures stable and reliable quality.
