كيف ننظف أسطح GRC المتسخة؟ دليل تقني احترافي للتنظيف من تشينغلونغ لـ GRC

Scientific cleaning of GRC surfaces is a crucial part of maintaining their aesthetics and functionality. Differentiated cleaning solutions are required depending on the type of dirt and the degree of contamination. Based on 28 years of maintenance experience, Qinglong GRC has developed a professional cleaning technology system tailored to different contamination scenarios.

In a cultural center project in Beijing, the GRC curtain wall was heavily polluted by smog. Qinglong adopted a three-stage cleaning plan: pretreatment using a neutral cleaning agent to soften attached deposits; main cleaning with low-pressure steam (0.3MPa, 50°C) combined with soft-bristle brushes; and post-treatment by spraying an anti-fouling coating. This solution removes stubborn stains while keeping the material damage rate below 0.1%. For carved texture areas in particular, ultrasonic atomization cleaning technology was used, perfectly preserving the detail features. After cleaning, the color difference of the project was ΔE≤2, meeting museum-grade cleaning standards.

Routine Dust Cleaning

Remove surface dust monthly with a soft brush or vacuum cleaner. Each quarter, rinse with a neutral cleaning agent (pH6-8) and clean water at a pressure ≤3MPa. Wipe key areas with a cotton cloth to avoid scratching the surface.

Stubborn Stain Treatment

For oil stains, soak with a special emulsifier for 10 minutes before washing. Treat rust spots by spot-applying oxalic acid solution (concentration ≤3%). For biological fouling, pretreat with an anti-mold agent followed by physical removal. These methods specifically address special stains.

Deep Cleaning Process

Carry out a thorough cleaning every 2-3 years using steam cleaning equipment. Use ultrasonic cleaning technology for intricate carved areas. After cleaning, a hydrophobic agent must be sprayed to form a protective film. This deep cleaning restores the material's natural color.

Cleaning in Special Environments

Coastal areas require an additional desalination step to prevent chloride ion corrosion. Industrial zones need focused treatment of acid rain marks. In northern regions, pay attention to the timing of cleaning during freeze-thaw periods. These location-specific measures ensure effective cleaning.

Professional cleaning requires scientific methods. Qinglong GRC provides cleaning technical guidance and cleaning agent supply services.
