كيف يتم الحفاظ على GRC؟ تحليل كامل لمنظومة الصيانة العلمية

Scientific maintenance of GRC products is the 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 tracking surveys, GRC projects that undergo scientific maintenance have a 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 achieved remarkable results. The plan includes a multi-level maintenance mechanism consisting of quarterly inspections, annual testing, and triennial overhauls. Over the project's 5 years of use, quarterly drone inspections promptly identified and addressed 3 potential issues; annual comprehensive inspections combine infrared thermal imaging with the tapping method to systematically check for hollowing and cracks; and the triennial overhaul focuses on addressing aging of joint sealants. This systematic maintenance has kept the building's GRC curtain wall at an integrity rate above 98% 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 anchor points. Use drones equipped with high-definition cameras for large-area inspections, improving efficiency 5-fold. Annual comprehensive testing should include load-bearing capacity verification and material performance testing. Such preventive inspections can promptly identify hidden risks.

Cleaning and Maintenance Standards

Perform routine cleaning every 6 months using pH-neutral specialized cleaning agents. Clean promptly after sandstorms or acid rain to prevent corrosion. During cleaning, water pressure should be controlled at 3-4 MPa and water temperature should not exceed 60℃. These standards prevent secondary damage.

Repair Processing Standards

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

Protection Enhancement Measures

Reapply protective agents every 5 years to improve stain resistance. Coastal areas require more frequent anti-corrosion treatment. Impact protection devices can be installed at critical locations. These measures extend service life.

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