防火玻璃是通过特殊化学处理在高温状态下进行二十多小时离子交换，替换了玻璃表面的金属钠，形成化学钢化应力层，同时通过物理处理后，玻璃表面形成高强的压应力，大大提高了抗冲击强度，当玻璃破碎时呈现微小颗粒状态，减少对人体造成伤害，强度是普通玻璃的6-12倍，是钢化玻璃的1.5-3倍！

The fireproof glass is treated by special chemical treatment at high temperature for more than 20 hours ion exchange, replacing the metal sodium of the glass surface, forming a chemical steel stress layer. At the same time, after physical treatment, the glass surface forms a high-strength compressive stress, which greatly improves the impact strength and presents tiny particles when the glass is broken. State, reduce damage to human body, intensity is 6-12 times of ordinary glass, 1.5-3 times of tempered glass.
