كيف نجري صيانة GRC؟ تحليل شامل لنظام الصيانة العلمي من تشينغلونغ لـ GRC

Scientific maintenance of GRC products is key to ensuring their long-term performance. As an industry leader with 28 years of GRC R&D and manufacturing experience, Qinglong GRC has established a comprehensive maintenance system of "prevention first, combining prevention with treatment" based on extensive engineering practice data. According to follow-up surveys, GRC projects with scientific maintenance can have their service life extended by more than 30%, with maintenance costs reduced by 40%.

In the Shenzhen Yirui Biotechnology Building project, the specialized maintenance plan Qinglong developed for its GRC curtain wall system has achieved remarkable results. The plan includes a multi-level maintenance mechanism of quarterly inspections, annual testing, and triennial overhauls. Over 5 years of operation, quarterly drone inspections have promptly identified and addressed 3 potential issues; annual comprehensive testing combines infrared thermal imaging with the tapping method to systematically check for hollowing and cracks; the three-year overhaul focuses on aging joint sealant. This systematic maintenance has kept the building's GRC curtain wall at over 98% integrity to date, with maintenance costs at only 0.8% of construction cost per year, far below the industry average.

Regular Inspection System

Establish a quarterly inspection mechanism, focusing on key areas such as joints and anchoring points. Drones equipped with HD cameras are used for large-area inspections, improving efficiency by 5 times. Annual comprehensive testing should include load-bearing capacity verification and material performance testing. This preventive inspection can promptly identify hidden dangers.

Cleaning and Maintenance Standards

Perform routine cleaning every 6 months using pH-neutral specialized cleaning agents. After sandstorms or acid rain, clean promptly to prevent corrosion. Water pressure during cleaning should be controlled at 3-4MPa, with water temperature not exceeding 60°C. These standards prevent secondary damage.

Repair Handling Standards

Cracks with a width of ≤0.2mm are treated with low-pressure grouting. Localized hollowing with an area of ＜0.1㎡ can be locally reinforced. Loose anchors must be replaced immediately. These standards ensure repair quality.

Enhanced Protection Measures

Reapply protective coating every 5 years to improve stain resistance. Coastal areas require increased frequency of anti-corrosion treatment. Important areas can be fitted with anti-collision protection devices. These measures extend service life.

Scientific maintenance requires systematic planning. It is recommended to develop a detailed maintenance manual and select a professional team for execution. Qinglong GRC provides comprehensive after-sales maintenance guidance services.
