防火玻璃是通過特殊化學處理在高溫狀態下進行二十多小時離子交換，替換了玻璃表面的金屬鈉，形成化學鋼化應力層，同時通過物理處理后，玻璃表面形成高強的壓應力，大大提高了抗沖擊強度，當玻璃破碎時呈現微小顆粒狀態，減少對人體造成傷害，強度是普通玻璃的6-12倍，是鋼化玻璃的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.
