China Suppliers Factory for High-Quality Solar Thermal Oven Belts and PV 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

Frequently Asked Questions
Q1: What materials are used in Huada solar drying oven mesh belts?
Our belts are manufactured using high-grade 316L stainless steel with a specialized anti-static coating, ensuring maximum chemical resistance and durability in PV production environments.
Q2: How does the belt reduce wafer breakage rates?
The design features rounded edge guides and an ESD-safe surface (10⁶-10⁹Ω resistance), which protects thin wafers (down to 160μm) and reduces breakage rates to less than 0.05%.
Q3: Are these drying belts resistant to acidic cleaning agents?
Yes, the electropolished 316L structure is engineered to withstand 1-10% HF and HNO3 residuals, passing 1,000-hour salt spray tests for superior corrosion resistance.
Q4: What makes the drying process 30% faster than standard belts?
The 85% open area design allows for optimal laminar airflow, while the mirror-polished surface minimizes water adhesion, leading to significantly faster moisture removal.
Q5: Can these belts be used for TOPCon or monocrystalline cell production?
Absolutely. They are specifically engineered for high-efficiency cell lines like TOPCon, where zero metal contamination (
