鋼化玻璃其實是一種預(yù)應(yīng)力玻璃，為提高玻璃的強(qiáng)度，通常使用化學(xué)或物理的方法，在玻璃表面形成壓應(yīng)力，玻璃承受外力時首先抵消表層應(yīng)力，從而提高了承載能力，增強(qiáng)玻璃自身抗風(fēng)壓性，寒暑性，沖擊性等。

In fact, tempered glass is a kind of prestressed glass. In order to improve the strength of glass, it usually uses chemical or physical methods to form pressure stress on the surface of glass. When the glass bears the external force, it first counteracts the stress of the surface, thus improving the bearing capacity, enhancing the anti wind pressure, heat and shock, and so on.
