Comprehensive Guide to Aluminum Plate Protective Film Application
Proper use of protective film on aluminum plates requires standardized operations from preparation through installation, maintenance, and removal to ensure optimal protection.
Film Selection
Choose film based on aluminum plate purpose: scratch-resistant for processing, UV-resistant for outdoor use. Match viscosity to surface roughness:
| Surface Type | Recommended Viscosity |
|---|---|
| Smooth Surface | 30-50g low viscosity |
| Rough Surface | 50-80g medium viscosity |
Surface Preparation
Thoroughly clean with alcohol and lint-free cloth to remove oils, dust, and moisture. Use specialized cleaners if needed to ensure optimal bonding surface.
Installation
Maintain 15-30°C temperature and 40-70% humidity. Peel backing from one corner while using a rubber squeegee to smooth from center outward, eliminating bubbles.
Maintenance
Avoid sharp objects that could scratch film. Clean only with damp cloth - no corrosive cleaners. Store away from light/moisture with ≤1.5m stacking height.
Removal Guidelines
- Maximum application time: 3 months (reduce to 1 month in high heat)
- Remove at 20-25°C ambient temperature
- Use hair dryer on low heat (≤60°C) to soften adhesive
- Peel slowly at 45° angle to minimize residue
- For remaining glue: use isopropyl alcohol or specialized remover (test first)
Critical Safety Note:
Always test cleaning solutions and removal methods on a small, inconspicuous area of the aluminum plate before full application to verify compatibility and prevent surface damage.
Key Recommendations
- Select film type based on intended use and surface characteristics
- Ensure perfect surface preparation before application
- Maintain proper environmental conditions during installation
- Follow recommended maintenance and storage practices
- Remove film within specified timeframes using proper techniques
By following these comprehensive guidelines for protective film selection, application, maintenance, and removal, you can ensure maximum protection for aluminum plates while maintaining surface quality throughout the entire process lifecycle.
