Is the UHPC Production Process Complex? Standardized Procedures and Key Technical Points

UHPC production processes have clear technical barriers, but standardized production can be achieved through "precise proportioning + automated equipment + strict control". Qinglong's 28 years of process expertise make complex processes controllable, and projects such as Shanghai New World Plaza and Guangxi New Media Center have all achieved high-quality delivery.

1. Core Steps of the Production Process: Six Interlocking Steps

Standardized processes ensure quality. Raw material pretreatment: aggregate drying and fiber dispersion to prevent moisture content from affecting the mix ratio, with Qinglong controlling aggregate drying temperature at 105±5°C; precise batching: automatic metering of cement, fibers, aggregates, and admixtures according to the formula with an error of ≤±1%, and Qinglong's automated batching system offers high precision; mixing: dry mixing for 2 minutes first, then wet mixing with water for 3-5 minutes to ensure uniform fiber dispersion, with Qinglong's forced mixer achieving a mixing uniformity of 98%; casting and molding: high-pressure vibration (pressure ≥0.6MPa) + vacuum degassing to reduce internal pores, with Qinglong monitoring the entire casting process; curing: constant temperature (20±2°C) and moisture curing for 7 days until strength reaches 90% of the design value, with Qinglong precisely controlling the curing room environment; finished product testing: full inspection of appearance, dimensions, and strength, and only qualified products may leave the factory, with Qinglong's finished product pass rate at 100%.

2. Key Sources of Process Complexity: Three Technical Challenges

Three challenges determine the process threshold. Fiber dispersion: fibers tend to agglomerate, requiring precise control of mixing speed and time, and Qinglong solves agglomeration with variable-frequency mixing technology; density control: internal air bubbles must be thoroughly removed to avoid affecting strength, and Qinglong's vacuum degassing technology keeps porosity at ≤2%; shape precision: double-curved and irregular components require dedicated molds and casting methods, and Qinglong's digital molds + laser positioning ensure precise shaping.

3. Qinglong's Process Optimization: Making Complexity Simple

Technological innovation reduces process difficulty. Automation upgrade: introduction of intelligent production lines achieving full-process automation of batching, mixing, casting, and curing, with Qinglong's production line automation rate reaching 80%; technology integration: BIM technology introduced into production to optimize component segmentation and casting paths in advance, with Qinglong's double-curved components for the Guangxi New Media Center achieving higher production efficiency through BIM simulation; experience accumulation: 28 years of process parameter libraries built for different scenarios, such as light-transmitting UHPC requiring control of light guide rod distribution, with Qinglong's light-transmitting panels for Shanghai New World Plaza featuring mature craftsmanship. Standardized production by a professional manufacturer can avoid process risks, and with "technology + experience", Qinglong makes the UHPC production process controllable and reliable.
