Why does Silk Screen Printed Glass need to be tempered at high temperature during the production process?

Silk Screen Printed Glass is a process that uses screen printing technology to print various patterns, texts or colors on the surface of glass. This technology is widely favored for its high precision, multi-color printing capabilities and good adaptability to complex patterns. After printing, the glass usually undergoes a series of subsequent treatments to enhance its physical properties and aesthetics.
High-temperature heat tempering treatment forms a compressive stress layer on the surface of the glass by rapid cooling, which greatly enhances the bending strength and impact resistance of the glass. When tempered glass is subjected to external forces, it is not easy to break, and even if it breaks, it will form smaller, relatively harmless fragments, thereby improving its toughness. Tempering treatment can significantly improve the thermal stability of glass, making it less likely to deform or break in an environment with sudden temperature changes. When tempered glass breaks, the fragments formed are smaller and the edges are smoother, which greatly reduces the risk of injury to the human body and improves the safety of the product.
The Silk Screen Printed Glass is sent to the tempering furnace and heated to a temperature close to its softening temperature. The purpose of this step is to make the molecular structure inside the glass looser in preparation for the subsequent rapid cooling. When the glass is heated to a predetermined temperature, it is quickly sent into a cooling medium (usually air or water) for rapid cooling. This step forms a compressive stress layer on the surface of the glass and a tensile stress layer inside. As the temperature gradually decreases, the stress inside the glass gradually tends to balance. At this time, the surface compressive stress layer will exist for a long time, providing a lasting strengthening effect for the glass.
High-temperature heat tempering treatment usually does not have a significant impact on the screen-printed pattern, so the integrity and clarity of the printed pattern can be ensured. The tempered Silk Screen Printed Glass not only has stronger physical properties and higher safety, but also maintains its original beauty and practicality. This makes it an ideal choice for high-end furniture, advertising counters, company front desk decoration and other fields. Through high-temperature heat tempering treatment, the performance of Silk Screen Printed Glass is significantly improved, thereby improving its market competitiveness and added value.
