The monolithic cesium-potassium fire-retardant glass is subjected to special chemical treatment for more than 20 hours of ion exchange at a high temperature, replacing the metal sodium on the glass surface to form a low-expansion silicate glass with an expansion coefficient of 1.8*10-6/0F. (3.24*10-6/K), so it has high heat resistance. At the same time, after physical treatment, high compressive stress is formed on the surface of the glass, which greatly improves the impact strength. When the glass breaks, it shows a state of tiny particles, reducing the The human body causes damage! The strength of a single piece of yttrium-potassium fire-resistant glass is 6-12 times that of ordinary glass and 1.5-3 times that of tempered glass!
