Optimizing glass product quality through a печь для закалки стекла requires precise control over multiple factors, включая температуру, время отопления, скорость охлаждения, и обработка стекла. Оптимирование качества стеклянной продукции через стеклянную печь - это сложный процесс, который включает в себя тщательный контроль и мониторинг нескольких факторов.
1. Предварительные процессы (Перед печью):
Выбор стекла & Качество:
Raw Material Quality: Start with high-quality glass sheets free of inclusions, пузырьки, or surface defects.
Glass Thickness & Type: Ensure the glass type (например, float glass, низкоэмиссионное стекло) is suitable for tempering and that the thickness is within the furnace’s capabilities. Incorrect thickness can lead to uneven heating and tempering.
Чистота: Thoroughly clean the glass before it enters the furnace. Contaminants like dust, нанесите вазелин, or fingerprints can cause uneven heating, spotting, or adhesion issues. Use appropriate glass cleaners and deionized water for rinsing.
Резка & Edge Work:
Accurate Cutting: Precise cutting is crucial for uniform heating and stress distribution. Use automated cutting tables and laser alignment systems for optimal accuracy.
Edge Processing: Smooth, polished, and defect-free edges are critical. Chips, трещины, or sharp edges can act as stress concentrators, leading to breakage during or after tempering. Use grinding, полировальный, or seaming machines to achieve high-quality edges.
Hole Drilling/Notching (если это применимо): Carefully drill or notch holes before tempering. Sharp corners or imperfections around holes are significant stress points. Use CNC machining with precise settings.
Low-E Coating Consideration:
Coating Compatibility: Ensure the low-E coating is compatible with the tempering process. Some coatings may require specific temperature profiles or protective measures.
