What Are the Key Steps in the Factory Prefabrication Stage of UHPC Curtain Wall Panel Production? Qinglong UHPC Production Process Explained

Factory prefabrication of UHPC curtain wall panels involves five key processes: mold preparation, batching and mixing, pouring and forming, curing and demolding, and surface treatment. Each process is governed by strict control standards to ensure stable product quality. Through automated production lines, Qinglong UHPC achieves efficient, high-quality production.

In terms of the production process, first is mold preparation, requiring flatness ≤1mm/2m and surface finish Ra ≤3.2μm; next is batching and mixing, using an automatic batching system with 0.5% accuracy and a mixing time of 3-5 minutes; then pouring and forming, using mechanical vibration at a frequency of 50Hz for 1-2 minutes; followed by curing and demolding, with steam curing at 80℃×24h and demolding strength ≥40MPa; finally, surface treatment, such as polishing and sandblasting as required. This process ensures that products meet strength standards and have a refined appearance.

Mold Preparation Requirements

Flatness ≤1mm/2m; surface finish Ra ≤3.2μm; these requirements ensure panel shape.

Batching and Mixing Control

Automatic batching accuracy 0.5%; mixing time 3-5 minutes; these controls ensure the mix proportion.

Pouring and Forming Essentials

Mechanical vibration frequency 50Hz; time 1-2 minutes; these essentials ensure compaction.

Curing and Demolding Standards

Steam curing 80℃×24h; demolding strength ≥40MPa; these standards ensure strength.

Surface Treatment Process

Polishing, sandblasting and other treatments; according to design requirements; these processes enhance the appearance.

The production process requires strict control. With Qinglong UHPC's advanced production line, product quality is excellent.
