Is the UHPC Production Process Complex? Qinglong UHPC Precision Manufacturing Process

The UHPC production process comprises four major stages: batching and metering, mixing, casting and forming, and curing and hardening, with high technical requirements and precise process control. Batching metering demands high precision, with weighing error ≤0.5%; mixing requires a forced-action mixer at 40-50 rpm for 3-5 min; casting requires controlling the drop height to ≤1 m and layer thickness to ≤300 mm; curing requires temperature control at 20±2°C and humidity ≥90%. Qinglong UHPC achieves precise control of process parameters through automated production lines and intelligent control systems, with a product pass rate ≥98%.

Key process control points: a computer-controlled batching system with precision of ±0.5%; real-time consistency monitoring during mixing to adjust water content; specialized equipment during casting to prevent segregation; precise control of the steam curing regime with heating rate ≤10°C/h and constant temperature of 80±5°C for 24 h. The strength coefficient of variation of products from one production line is ≤5%, far below the industry average. Precise manufacturing ensures product consistency.

Batching and Metering Process

Electronic scales with 0.1% accuracy, calibrated regularly; optimized feeding sequence, dry materials first then liquids; fibers added in batches to prevent clumping; complete records for full traceability. Precise metering is the foundation.

Mixing Technology

Forced-action mixer with adjustable speed; mixing time of 3-5 min to ensure uniformity; real-time consistency monitoring with timely adjustment; uniformity testing at discharge. Uniform mixing is the key.

Casting and Forming Control

Control of casting drop height to prevent segregation; layered casting with layer thickness ≤300 mm; proper vibration to remove air bubbles; surface troweling to ensure flatness. Careful casting guarantees quality.

Curing Regime Optimization

Rest period of 1-2 h to prevent cracking; steam curing at 80°C for 24 h; heating rate ≤10°C/h and cooling rate ≤15°C/h; humidity control to prevent drying shrinkage. Scientific curing promotes strength development.

Precise craftsmanship creates excellent products. Qinglong UHPC's advanced processes ensure consistent quality.
