Frequently Asked Questions
Q1
What material is used in Jiangsu Huada's drying oven belts?
The belts are constructed from premium 316L electropolished stainless steel with an anti-static coating, specifically engineered for PV backsheet E-coating and pre-lamination drying processes.
Q2
How does the mesh belt perform under acidic washdown conditions?
It provides superior chemical resistance, withstanding 1-10% HF and HNO3 residuals while successfully passing the 1,000-hour ASTM B117 salt spray test.
Q3
How does the belt achieve faster and more uniform drying?
The belt features an 85% open area design that enables laminar airflow and a mirror-polished surface (Ra ≤0.4μm) to minimize water adhesion, resulting in 30% faster drying cycles and ±1.5% RH drying uniformity.
Q4
What protection does the conveyor system offer for fragile, thin wafers?
The system provides ESD safety (surface resistance 10⁶-10⁹Ω), a standoff structure to reduce contact area, and rounded edge guides that lower breakage rates down to 0.03% on 160μm wafers.
Q5
What residual moisture and contamination levels can be expected?
The conveyor system achieves < 5ppm residual moisture verified by FTIR analysis and zero metal contamination with ICP-MS testing below 0.1ppb.
Q6
What cost and efficiency benefits have TOPCon cell manufacturers realized?
Customers have achieved a reduction in wafer breakage rate from 0.18% to 0.03%, annual LN2 cost savings of €75,000, and zero corrosion after 3-year DH2000 reliability testing.
