Solar Thermal Oven Belts for Module Assembly
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 (Bullet Points)
√ 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%
