When choosing honeycomb panels, environmental protection is key! To determine its environmental protection level, mainly look at these three points: formaldehyde emission level, surface treatment, and authoritative certification. Let me help you quickly grasp the key points:
Formaldehyde Emission Level: The Most Core Hard Indicator
This is the gold standard for judging environmental protection and directly relates to indoor air quality.
The most stringent level: ENF level (≤0.025mg/m³) or E0 level (≤0.050mg/m³), the first choice for healthy homes.
Common level: E1 level (≤0.124mg/m³), meets national standards, but ENF/E0 is better.
How to obtain: Check the formaldehyde emission level value on the product testing report or official certification label.
Surface Treatment: The Key to Long-Term Environmental Protection and Durability
Good treatment can effectively prevent the release of harmful substances and ensure the long-lasting beauty of the panels.
Superior Craftsmanship: Major brands typically use a coating process, resulting in a tight bond between the coating and the aluminum material, making it environmentally friendly and corrosion-resistant. The back coating uses imported anti-rust coatings, guaranteeing no rust for over 20 years.
Ordinary Craftsmanship: The coating is thin, easily peels off, and may lead to formaldehyde release, rusting, and discoloration, resulting in poor environmental performance.
