What Is the GRC Production Process? A Detailed Look at Qinglong's GRC Manufacturing Technology System

The GRC production process mainly consists of four key stages: batching, mixing, molding, and curing. High-quality GRC ensures stable product performance through precise process control. With automated production lines and strict quality control, Qinglong GRC achieves a first-pass yield of 99.2%.

In terms of production technology, Qinglong GRC uses advanced equipment: a German BHS mixer (batching accuracy of 0.1%); a robotic spray system (even fiber distribution); and intelligent curing kilns (temperature and humidity control of ±1°C). This precise control keeps the product strength coefficient of variation within 5%, far below the 15% required by industry standards.

Batching Process Precision Control

An automatic batching system with 0.1% accuracy is used; raw material feeding is fully automated; and a formula management system ensures accurate proportions. These form the foundation of quality.

Mixing Process Optimization

Planetary mixers are used with linear speed controlled at 3 m/s; mixing time of 4-6 minutes; and fiber dispersion uniformity ≥95%. These ensure workability.

Molding Process Innovation

Spray molding provides precise thickness control; vacuum dewatering improves compactness; and vibration compaction eliminates air bubbles. These processes enhance quality.

Scientific Curing Regime

Curing in molds for 24 hours; humidity ≥90%; and water curing for 7 days after demolding. These ensure strength development.

The production process requires precise control. Through its comprehensive process system, Qinglong GRC ensures outstanding product quality.
