كيف نجري صيانة GRC؟ دليل تشينغلونغ للصيانة العلمية لـ GRC

As a high-performance building material, the maintenance of GRC products directly affects their service life and aesthetic appearance. Based on 28 years of engineering practice, Qinglong GRC has developed a scientific maintenance system. Through regular inspections, professional cleaning, timely repairs, and preventive protection, GRC products can remain in good condition for the long term.

In the Shenzhen Yirui Biotechnology Building project, the maintenance plan implemented by Qinglong achieved remarkable results: two comprehensive inspections per year, with drone-assisted surveying of high-altitude areas; professional cleaning once per quarter using neutral cleaning agents and soft tools; and the establishment of digital maintenance records documenting each maintenance activity. Over 5 years of operation, the GRC curtain wall system has remained like new with no degradation in strength performance, and maintenance costs have been reduced by 30% compared to expectations. In particular, to address the rainy southern climate, anti-mold treatment and water seepage detection were added, effectively preventing common problems.

Key Points for Regular Inspection and Maintenance

A comprehensive inspection is recommended every six months, focusing on joint sealing, surface coating integrity, and fastener security. Use the tapping method to check for hollow spots and mark any issues immediately. Establish an inspection record sheet to track problem resolution progress.

Standard Procedure for Professional Cleaning

Cleaning frequency depends on environmental conditions, generally once per quarter. Use a pH-neutral specialized cleaning agent together with a soft brush or sponge. Keep high-pressure water gun pressure between 50-80 Bar, with the nozzle at least 30cm from the panel surface. After cleaning, check that the drainage system is unobstructed.

Preventive Maintenance Measures

Consider using anti-fouling coatings in heavily polluted areas. Coastal areas require enhanced anti-salt-spray treatment. Regularly check the integrity of the waterproofing layer and reapply protective agents promptly. Establish a preventive maintenance plan to eliminate problems at an early stage.

Requirements for Professional Maintenance Teams

Maintenance personnel must receive professional training and be familiar with GRC characteristics. Workers performing tasks at heights must be certified and equipped with safety protection gear. Establish an emergency maintenance mechanism with responses to sudden problems within 24 hours.

Scientific maintenance can significantly extend the service life of GRC. It is recommended to develop a detailed maintenance plan and implement it strictly to maximize investment value.
