Optimizing glass product quality through a horno de templado de vidrio requires precise control over multiple factors, incluyendo la temperatura, heating time, cooling rate, and glass handling.Optimizing glass product quality through a glass tempering furnace is a complex process that involves careful control and monitoring of several factors.
1. Pre-Tempering Processes (Before the Furnace):
Glass Selection & Calidad:
Raw Material Quality: Start with high-quality glass sheets free of inclusions, bubbles, or surface defects.
Glass Thickness & Type: Ensure the glass type (p.ej., float glass, vidrio de baja emisividad) is suitable for tempering and that the thickness is within the furnace’s capabilities. Incorrect thickness can lead to uneven heating and tempering.
Limpieza: Thoroughly clean the glass before it enters the furnace. Contaminants like dust, aplicar vaselina, or fingerprints can cause uneven heating, spotting, or adhesion issues. Use appropriate glass cleaners and deionized water for rinsing.
Corte & 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, grietas, or sharp edges can act as stress concentrators, leading to breakage during or after tempering. Use grinding, pulido, or seaming machines to achieve high-quality edges.
Hole Drilling/Notching (si es aplicable): 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.
