ما هي عملية إنتاج GRC؟ تحليل شامل لعملية تصنيع تشينغلونغ لـ GRC

The GRC production process directly affects product performance and consistency. High-quality GRC adopts processes such as spraying, premixing, and mesh laying, selecting the optimal solution according to product requirements. Through 28 years of process optimization, Qinglong GRC has developed a precision production system.

In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, Qinglong adopted an improved spraying process to produce double-curved GRC panels: automatic spraying via robotic arms keeps the fiber content controlled at 4.5%-5% with distribution uniformity above 95%; vacuum dewatering reduces the water-cement ratio to 0.30, improving density; low-temperature steam curing (65℃±2℃) optimizes strength development. This process achieves a product flexural strength of 25MPa, with the strength coefficient of variation controlled within 5%. The online inspection system adopted in the project monitors process parameters in real time to ensure stable product quality. This precision control kept the dimensional errors of tens of thousands of shaped panels within ≤2mm.

Batching Process Control

The electronic weighing system has a precision of ±0.1%. Dry materials are premixed for 2 minutes to ensure uniformity. Fibers are added in three batches to prevent clumping. The water-cement ratio is controlled at 0.30-0.33. These controls ensure accurate mix proportions.

Forming Process Selection

The spraying process offers good fiber orientation, suitable for complex components. The premix process is highly efficient, suitable for standard panels. The mesh-laying process enhances directional reinforcement, suitable for special areas. Each of these processes has its own advantages.

Curing Regime Optimization

A resting period of 2-3 hours prevents plastic cracks. A heating rate of ≤15℃/h avoids thermal stress. 24 hours of constant-temperature curing ensures strength development. A cooling rate of ≤20℃/h prevents shrinkage cracks. This regime optimizes performance.

Post-Treatment Process

After demolding, products undergo 7 days of water curing to promote strength development. Surface treatment improves durability. Quality inspection covers 100% of products. These procedures ensure factory quality.

Advanced processes require precision control. Qinglong GRC ensures process stability through automated production lines.
