During the entire lifespan of UV boards, scientific maintenance extends durability, while prompt fault diagnosis ensures optimal performance. Regular care, inspections, and repairs keep UV boards in top condition.
I. Daily Maintenance Guidelines
1. Cleaning Best Practices
Use soft damp cloths for daily cleaning; avoid abrasive tools. For tough stains, apply diluted neutral detergents (pH 7 – 8). Proper cleaning maintains ≥90% gloss over 5 years, according to testing.
2. Environmental Adaptation
Prevent exposure to extreme heat (>60℃) or humidity (>85%). In a southern residence case, dehumidifiers reduced mildew occurrence by 90% and deformation by 80%.
II. Periodic Maintenance Protocols
1. Semi – Annual Inspections
Check joint sealants for cracks, especially in wet areas. Use hygrometers to monitor humidity behind boards; take measures if over 70%.
2. Annual Professional Servicing
Hire experts for surface polishing and scratch repair. Apply anti – rust agents to metal trims, extending lifespan by 3 – 5 years.
III. Common Fault Diagnosis and Repair
1. Local Coating Peeling
- Cause: Incomplete curing or impact damage.
- Fix: Touch up with matching UV paint and cure with a small UV lamp for 3 – 5 minutes.
2. Surface Yellowing
- Cause: Poor UV resistance or sunlight exposure.
- Fix: Polish for mild cases; re – coat for severe yellowing.
3. Joint Cracking
- Cause: Substrate movement or sealant failure.
- Fix: Refasten the base, replace with elastic sealant (displacement capacity ≥25%), fill to 1/2 joint depth.
IV. Advanced Longevity Strategies
1. Seasonal Protection
Install sun protection films on south – facing UV boards in summer, reducing surface temperature by 10 – 15℃. In winter, manage indoor – outdoor temperature differences to prevent condensation.
2. Intelligent Monitoring
Deploy sensors for temperature, humidity, and displacement. A commercial complex using this system achieved 95% fault prediction accuracy and 30% maintenance cost savings.
