The core of protecting FRP panels after installation lies in preventing physical scratches, chemical corrosion, and UV aging. The focus of protection measures varies depending on the usage scenario (e.g., floor, wall, equipment platform).
The following are specific protection methods and precautions:
I. Physical Protection (Scratch and Impact Protection)
The surface hardness of FRP panels is relatively low, making them easily scratched by sharp objects, affecting aesthetics and corrosion resistance.
1. Setting Up Warnings and Isolation:
Set up clear warning signs in the installation area to remind personnel to take precautions.
* When moving heavy objects or carrying out overlapping construction work, lay rubber mats, wooden boards, or thick cardboard on the FRP surface as a cushioning layer to prevent direct dragging of heavy objects or tools.
2. Walking and Transportation Standards:
Walking on the surface with shoes containing nails is strictly prohibited.
If using handcarts or other transportation tools, ensure that the wheels are made of rubber or nylon to avoid direct running over metal wheels.
II. Chemical Protection (Corrosion Prevention)
Although FRP is inherently corrosion-resistant, prolonged contact with strong acids, alkalis, or organic solvents can still cause damage.
1. Timely Cleaning:
If chemicals (such as acids, alkalis, or oil) are spilled on the surface, immediately rinse with plenty of water and dry with a soft cloth.
* Avoid using strong corrosive chemical solvents (such as concentrated sulfuric acid or acetone) for cleaning.
2. Cleaning Agent Selection:
* For daily cleaning, it is recommended to use a neutral detergent or mild soapy water. Never use metal brushes, steel wool, or other hard objects to scrub.
III. Environmental Protection (Anti-aging)
Ultraviolet radiation is the main factor causing FRP aging. Prolonged exposure to sunlight will cause the surface resin to chalk and the color to fade.
1. Surface Coating Protection:
For FRP panels that are exposed to the outdoors for extended periods, it is recommended to apply a layer of UV-resistant topcoat or gel coat after installation. This will not only effectively delay aging but also maintain vibrant colors.
* Regularly check the coating integrity; repair any peeling immediately.
2. Avoid high-temperature baking:
The heat resistance temperature of fiberglass is typically around 60-100℃ (depending on the resin type). Welding, gas cutting, and other high-temperature operations are strictly prohibited on the surface, as are prolonged placement of high-temperature objects to prevent deformation or combustion.
IV. Regular Inspection and Maintenance
1. Inspection Cycle: A comprehensive inspection is recommended every six months to one year.
2. Inspection Contents:
Surface Condition: Check for cracks, blistering, delamination, or abnormal color.
* Connection Points: Check for loose bolts and clamps, and for aged or cracked sealant.
Structural Deformation: Check for obvious sagging or twisting of the Panel.
3. Maintenance Measures:
For small-area damage (such as scratches or small holes), repair with matching color resin putty.
* For loose connectors, tighten or replace them promptly.
In summary, the key to protecting FRP (fiberglass reinforced plastic) flat panels after installation lies in "prevention first, timely handling." By combining physical isolation, chemical cleaning, and protective coatings, their service life can be significantly extended, maintaining their optimal performance.
