كيف تنظف سطح GRC المتسخ؟ دليل فني مهني لتنظيف GRC

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

In a cultural center project in Beijing, the GRC curtain wall was severely contaminated by smog, so Qinglong adopted a three-stage cleaning solution: pre-treatment using neutral detergent to soften attached deposits; main cleaning with low-pressure steam (0.3MPa, 50℃) combined with a soft brush; 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 textured areas in particular, ultrasonic atomization cleaning technology was used, perfectly preserving the detail features. After cleaning, the project's color difference was ΔE≤2, meeting museum-grade cleaning standards.

Daily Dust Cleaning

Remove surface dust monthly with a soft brush or vacuum cleaner. Every quarter, rinse with neutral detergent (pH6-8) combined with clean water at a pressure of ≤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. Rust stains are treated by spot-applying oxalic acid solution (concentration ≤3%). Biological dirt is pre-treated with a mildew inhibitor before physical removal. These methods specifically address special stains.

Deep Cleaning Process

A thorough cleaning is performed every 2-3 years using steam cleaning equipment. Ultrasonic cleaning technology is used for intricately carved areas. After cleaning, a hydrophobic agent must be sprayed to form a protective film. This deep cleaning restores the material's original color.

Cleaning in Special Environments

Coastal areas require additional desalination procedures to prevent chloride ion corrosion. Industrial areas should focus on treating acid rain marks. In northern regions, attention should be paid to the timing of cleaning during freeze-thaw periods. These site-specific measures ensure effective cleaning results.

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