TFT-LCD 溢流法玻璃 G6～G8.5 核心技术特点
Core Technical Features of TFT-LCD Overflow Down-Draw Glass (G6–G8.5)
⸻
一、高温熔融与均质控制技术
1. High-Temperature Melting and Homogenization Control
我司采用多区段精密温控系统，确保玻璃原料在约1600°C的高温下均匀熔融。
通过优化熔池流场与搅拌设计，有效消除气泡、条纹及成分偏析，保证大尺寸基板的成分稳定与光学均匀性。
Our company applies multi-zone precise temperature control to ensure uniform melting of raw materials at around 1600°C. By optimizing the melt flow field and stirring design, bubbles and striations are minimized, ensuring stable composition and optical uniformity for large-size substrates.

二、对称溢流槽设计（Isothermal Symmetric Overflow Trough）
2. Symmetrical Overflow Trough Design
我司采用白金铱合金制造的高精度溢流槽，玻璃熔体自中央溢出后双侧对称下流并在下方汇合成片。
此设计可保持流速、温度及厚度一致，防止因重力或冷却差异造成的厚度偏差与应力集中。
We utilize a high-precision platinum-iridium overflow trough, allowing molten glass to flow symmetrically down both sides. This design maintains uniform flow rate, temperature, and thickness, minimizing stress and thickness deviation caused by gravity or cooling imbalance.

三、非接触成形技术确保表面品质
3. Non-Contact Forming for Superior Surface Quality
在成形过程中，玻璃表面完全不接触任何固体模具，可直接获得原子级平整度（Ra < 0.5 nm）。
该特性确保TFT曝光、刻蚀等制程的精确对位，无需后续研磨或抛光处理。
During forming, the glass surface never contacts any solid mold, achieving atomic-level flatness (Ra < 0.5 nm). This ensures precise alignment in TFT processes such as exposure and etching, eliminating the need for post-polishing.

四、应力与冷却梯度精密控制
4. Precision Stress and Cooling Gradient Control
我司采用多段退火与区域冷却控制技术，透过张力及温差分布优化，有效降低热应力集中。
该技术使大尺寸玻璃在切割、搬运及后制程中保持结构稳定与高机械强度。
Our multi-zone annealing and cooling control technology optimizes tension and thermal gradients to minimize internal stress. This ensures high dimensional stability and mechanical strength during cutting, handling, and subsequent processing.

五、低碱高强度玻璃组成技术
5. Alkali-Free, High-Strength Glass Composition Technology
我司采用低碱铝硼硅系统（Alumino-borosilicate），具备低热膨胀、高硬度及高耐热特性。
优点包括：
• 避免碱离子污染导致TFT迁移率下降；
• 热膨胀系数与a-Si及IGZO材料匹配；
• 具备支撑G8.5世代以上大尺寸基板的结构强度。
We adopt an alumino-borosilicate alkali-free system with low thermal expansion, high hardness, and excellent heat resistance. Advantages include:
– Preventing alkali ion contamination that affects TFT mobility;
– Thermal expansion matching with a-Si and IGZO materials;
– High structural strength suitable for G8.5 and above large-size substrates.
