Features:
1. Enhanced Mechanical Strength: Tempered processing ensures surface hardness ≥7H (Mohs scale) and excellent impact resistance, preventing breakage from outdoor impacts (e.g., hail, debris).
2. Superior Light Transmittance: ≥90% (low-iron type ≥93%) visible light transmittance maximizes solar energy absorption, boosting the heating efficiency of solar water heater systems.
3. Exceptional Weather Resistance: Advanced coating and premium glass material resist UV radiation, extreme temperatures (-30℃ to +350℃), humidity, and salt spray, maintaining performance for ≥10-15 years outdoors.
4. Safety Compliance: Fully tempered structure breaks into small, blunt-edged fragments (no sharp shards), meeting international safety glass standards (ASTM C1048/EN 12150) for safe installation.
Application:
1. Commercial Solar Hot Water Projects: Applied in hotels, hospitals, schools, office buildings, and shopping malls. It supports large-scale solar water heating systems to supply hot water for public areas (e.g., hotel guest rooms, hospital wards, school dormitories), reducing energy costs and carbon emissions.
2. Industrial Solar Thermal Utilization: Used in industrial production processes that require medium-temperature hot water (e.g., food processing, textile dyeing, chemical production). It integrates with industrial solar collector systems to provide stable, low-cost thermal energy, replacing traditional fossil fuel heating.
