鋼化玻璃是將平板玻璃加熱到接近玻璃軟化溫度，并立即急劇冷卻而制成的。鋼化玻璃表面形成均勻的壓應(yīng)力，內(nèi)層呈現(xiàn)相應(yīng)的張應(yīng)力，所以鋼化玻璃是一種高強(qiáng)度的安全玻璃?？箯潖?qiáng)度和抗沖擊強(qiáng)度是普通玻璃的四倍以上。且破碎后，其碎片呈顆粒狀，提高了產(chǎn)品的使用安全性，因此，鋼化玻璃是目前應(yīng)用最廣泛的首選安全玻璃。

Tempered glass is made of plate glass heated to nearly glass transition temperature,and cooled immediately and rapidly.Due to even compressive stress on toughened glass surface, and the corresponding tensile stress in inner layer,toughened galass is a sort of high strength safety glass.Bending strength and shock strength are four times higher than common glass.When toughened glass is broken,the debris is granular and safe.Therefore, toughened glass is the first choice sagety galss with wide application at present.
