ما مدى فعالية حالات التعاون مع مصنع GRC؟ دراسة عملية للأداء الهندسي لمصنع تشينغلونغ لـ GRC

The application performance of GRC products in actual projects needs to be verified through the long-term service conditions of completed projects. Qinglong, a GRC manufacturer, establishes tracking archives for finished projects, collecting long-term product performance data through regular follow-up visits and testing, providing empirical support for material application.

A follow-up visit conducted 5 years after completion of the Shenzhen Yirui Biotechnology Building project showed: GRC curtain wall panels retained over 95% of their surface color, with no cracking or weathering, and a flexural strength retention rate of 96%. In the Wuhan Hanxiu Theater project, red GRC panels after 8 years of use showed a color change of ΔE≤3.2, fully within the acceptable range. At a coastal project in Hainan, after 8 years of exposure to the marine environment, components showed a carbonation depth of only 0.3mm and a chloride ion diffusion coefficient of 1.2×10⁻¹²m²/s. These long-term data strongly verify the durability of GRC and provide strong support for the promotion and application of the material.

Appearance Retention

Surface color remains stable over the long term, with no obvious staining or weathering. Joints are uniform and neat, with no deformation. This appearance has been well recognized.

Structural Performance Stability

Bearing capacity remains stable with no degradation. Connection joints are reliable with no loosening. Waterproofing performance is long-lasting with no leakage. This stability reflects the advantages of the material.

Functional Completeness

Design functional requirements are met, with convenient maintenance and low cost. Durability exceeds expectations; this performance strengthens user confidence.

User Satisfaction Feedback

Owners are satisfied with the performance, willing to choose GRC again, and actively recommend it to other projects. Such recognition is the most convincing.

Long-term service performance is the best proof. It is recommended to focus on projects completed more than 3 years ago to understand their real in-use performance.
