What should I do if I want to change the size of the glass after tempering?
钢化玻璃以其安全性成为目前最流行的玻璃之一。它的使用范围非常广泛,有很多人希望在购买钢化玻璃后将其切割成合适的尺寸进行使用。可是遗憾的是,钢化玻璃的特性决定了它并不适合切割处理。Tempered glass has become one of the most popular glass due to its safety. It has a very wide range of applications, and many people hope to cut it into a suitable size for use after buying tempered glass. Unfortunately, the characteristics of tempered glass determine that it is not suitable for cutting.
一、为什么钢化玻璃不能切割处理 Why can't tempered glass be cut?
钢化玻璃又称为安全玻璃。为了提高玻璃的性能,我们通过物理或化学方法加工普通玻璃,使其具有安全性、耐冲击力和热稳定性,处理后的玻璃,我们称之为钢化玻璃。Tempered glass is also called safety glass. In order to improve the performance of glass, we process ordinary glass through physical or chemical methods to make it safe, impact-resistant and thermally stable. The processed glass is called tempered glass.
钢化玻璃强度较之普通玻璃性能提高数倍,抗弯强度是普通玻璃的3~5倍;抗冲击强度是普通玻璃5~10倍;同时,钢化玻璃相比于普通玻璃更加安全。其承载能力加大,改善了玻璃易碎的特质,即使钢化玻璃被损坏,也会变成没有尖锐棱角的小碎片,大大降低人体受到伤害的可能性。钢化玻璃的耐温差性是普通玻璃的2~3倍,一般可承受150℃以上的温差变化,可防止玻璃因温差过大而发生自爆。The strength of tempered glass is several times higher than that of ordinary glass, and its bending strength is 3 to 5 times that of ordinary glass; the impact strength is 5 to 10 times that of ordinary glass; at the same time, tempered glass is safer than ordinary glass. Its load-bearing capacity is increased, which improves the fragile nature of glass. Even if the toughened glass is damaged, it will become small fragments without sharp edges and corners, which greatly reduces the possibility of human injury. The resistance of the temperature difference of tempered glass is 2 to 3 times that of ordinary glass, and it can generally withstand temperature changes above 150℃, which can prevent the glass from exploding due to excessive temperature difference.
正因为钢化玻璃具有上述特性,导致玻璃在钢化后不能再进行切割和加工,需要在普通玻璃钢化前就将其加工成需要的尺寸和形状,再进行钢化处理。Because of the above-mentioned characteristics of tempered glass, the glass cannot be cut and processed after tempering. It is necessary to process ordinary glass into the required size and shape before tempering, and then temper it.
二、玻璃进行钢化处理后还想改尺寸,怎么办? What should I do if I want to change the size of the glass after tempering?
如果玻璃已经完成钢化处理,再想改尺寸和形状,通常只能把原来的钢化玻璃作废,重新加工一块。因此,只有在订购钢化玻璃前确认好尺寸,才能节省成本。If the glass has been tempered, and then want to change the size and shape. IT CANT. Therefore, the cost can be saved only by confirming the size before ordering tempered glass.
