China Suppliers Solar Thermal Oven Belts Factory for Efficient Module Assembly and Wafer Drying Solutions
Products Description
Our solar drying oven mesh belts use 316L stainless steel with anti-static coating, designed for PV backsheet E-coating and pre-lamination drying. Chemical-resistant structure withstands acid washdown.
Jiangsu Huada’s PV cell drying oven belts are engineered for critical moisture removal in monocrystalline/polycrystalline silicon production. Our 316L stainless steel conveyor systems deliver:
- < 5ppm residual moisture (verified by FTIR analysis)
- 30% faster drying cycles vs. conventional mesh belts
- Zero metal contamination (ICP-MS tested to <0.1ppb)
Key Applications:
- Post-texturing cleaning drying
- PSG removal rinse drying
- Edge isolation process drying
Technical Advantages
Superior Chemical Resistance
- Withstands 1-10% HF / HNO3 residuals
- Passes 1,000-hour salt spray test (ASTM B117)
Optimized Drying Performance
- 85% open area design for laminar airflow
- Mirror-polished surface (Ra ≤0.4μm) minimizes water adhesion
Thin Wafer Protection
- ESD-safe (surface resistance 10⁶-10⁹Ω)
- Rounded edge guides reduce breakage to <0.05%
