Analysis of Forming Difficulty for Double-Curved GRC Panels of Different Thicknesses: Qinglong GRC Thickness Adaptability Technology

The forming difficulty of double-curved GRC panels increases exponentially with thickness. When panel thickness is ≤15mm, warping deformation is likely to occur; 15-25mm is the optimal forming range; at ≥25mm, shrinkage stress increases and internal defects are prone to form. Through mix proportion optimization (fiber content 2.5%-3.5%), process adjustment (vacuum degree -0.06 to -0.10MPa), and curing control (heating rate ≤10°C/h), high-quality forming of panels at different thicknesses can be achieved.

Technical countermeasures: For thin panels (≤15mm), increase the number of fiberglass mesh layers (2-3 layers) and control slump ≥200mm; for thick panels (≥25mm), adopt layered casting with interval time ≤ initial setting time, and set up temperature monitoring points. In a gradient-thickness panel (12-30mm) project, differentiated control achieved a forming pass rate ≥95%. Qinglong GRC thickness adaptation technology meets diverse needs.

Thin Panel Forming Technology

Increase fiber content to improve toughness; control flowability to avoid segregation; strengthen curing to prevent cracking; use formwork adsorption to reduce deformation. Thin panels require special care.

Key Control Points for Medium-Thick Panels

Optimize the mix proportion to reduce shrinkage; vibrate moderately to avoid over-vibration; monitor temperature to prevent thermal cracking; demold at the right time when strength is appropriate. Medium-thick panels balance difficulty and performance.

Technical Challenges of Thick Panels

Layered casting to control temperature rise; cooling systems to reduce core temperature; shrinkage compensation by adding expansion agents; slow curing to reduce stress. Thick panels require comprehensive measures.

Thickness Transition Treatment

Gradual design to avoid abrupt changes; reinforced bars to prevent cracks; special molds for precise control; enhanced inspection to ensure quality. Transition areas require special attention.

Different thicknesses require differentiated solutions. Qinglong GRC professional technology handles all kinds of challenges.
