english What should the temperature be controlled at when applying protective film to colored steel plates

Protective Film Application Guidelines for Colored Steel Plates
The optimal temperature range for applying protective film to colored steel plates is between 5°C and 35°C, as verified by practical experience.
Low Temperature Effects (Below 5°C)
When the temperature is too low:
- The adhesive layer loses activity due to low temperature
- Viscosity drops significantly
- Film struggles to adhere closely to the plate surface
- Microscopic gaps form, allowing water vapor penetration
- Later temperature increases cause thermal expansion differences
- Edges may warp or partially detach
Northern Winter Warning: Without proper temperature control, large-scale filming failures may occur during cold weather.
High Temperature Effects (Above 35°C)
When the temperature is too high:
- Adhesive softens and becomes overly fluid
- Glue may overflow during application
- Potential surface contamination when removing film
- High temperatures accelerate adhesive oxidation
- Premature aging and brittleness may occur
Important Considerations
- Surface temperature may differ from ambient by 5-10°C
- Direct sunlight can dramatically increase surface temperature
- Avoid midday application in outdoor settings
Recommended Application Times:
Summer: Before 10 AM or after 4 PM
Winter: 3 hours before/after noon
Extreme Temperature Solutions
For unavoidable extreme temperature work:
-
Use specialized films:
- Low-temperature film (-10°C to 5°C)
- High-temperature resistant film (35°C to 50°C)
- Always conduct small-area tests first
- Verify adhesive adaptation to temperature conditions
