化学钢化工艺对薄玻璃性能影响

Effect of Chemical Toughening Process on the Properties of Thin Glass

薄玻璃由于其优越的性能广泛用于电子显示领域,为了增加其抗弯强度、抗冲击强度、使用安全性能和维氏硬度,需要对其进行化学钢化处理。化学钢化分为一次化学钢化和二次化学钢化两种工艺,采用二次化学钢化工艺制备的玻璃性能明显提高,钢化支架影响被钢化玻璃的质量,通过在支架上缠绕两层不同直径的高硅氧玻璃纤维丝,隔绝玻璃与钢化支架的直接接触,减少钢化后玻璃表面缺陷的产生,提高化学钢化的成品率和质量。

Thin glass is widely used in the field of electronic display due to its superior performance. In order to increase its bending strength, impact resistance, safety performance and Vickers hardness, chemical toughening process must be carried out on it. The chemical toughening process is divided into two procedures, primary and secondary toughening procedures. The performance of glass prepared by secondary toughening procedure is improved significantly. The toughening support will affects the quality of toughened glass. By winding two layers of high silica glass fiber wires with different diameters on the support to avoid direct contact between glass and support,which can reduce the surface defects of toughened glass and improve the yield and quality of finished product.
