Tempered glass screen display

Nanjing Fu Rui Glass Industrial Co., Ltd. specializing in the production of chemical tempered glass screen. Chemically strengthened glass is a kind of prestressed glass, to enhance the strength of the glass, usually using chemical or physical methods, the glass surface compressive stress is formed, when the surface of the glass to withstand external force first counteract stress, thus improving the carrying capacity and enhance the glass itself wind pressure resistance, cold and heat resistance, impact resistance and so on. The main advantage of chemically tempered glass there are two, the first is several times greater than ordinary glass strength, bending strength is 3-5 times that of ordinary glass, impact strength is 5 to 10 times of ordinary glass, while also increasing the strength improved security. The use of safety glass is the second major advantage, its carrying capacity is increased to improve the fragile nature. Good thermal shock and chemical properties than ordinary glass glass of 2 to 3 fold increase in general can withstand temperature changes over 300LC, to prevent heat burst had a significant effect chemically strengthened glass is manufactured using low-temperature ion exchange process, and The so-called low temperature system refers to the range of switching temperature of not higher than the glass transition temperature, with respect to high-temperature ion exchange process at above the transition temperature, the softening point or less in terms of the temperature range. Low-temperature ion exchange process simple principle in an alkaline salt solution is about 400 ℃, and the glass surface of the solution ionic radius smaller radius larger ion exchange, such as glass and a lithium-ion solution of potassium or sodium ion exchange of sodium ions in the glass with the solution of potassium ion exchange, the use of alkali ions difference on volume embedded in the glass surface to form a compressive stress. Surface stress is proportional to the number of large ions crowded embedded glass surface, so the number of ion-exchanged with skin depth exchange is a key indicator enhancement effect. Different stress distribution and physical tempered glass ion exchange, the smaller the thickness of the former surface compressive stress layer, its internal tensile stress is not balanced, which is chemically tempered glass internal tensile stress layer is also not to destroy the physical steel As the reason broken into small pieces of glass. Since the ion exchange layer is thin, so thin chemically tempered glass method for enhancing the effect of significantly enhance the effect of the thick glass of the not so obvious, especially for enhanced 2 ~ 6mm thick glass Hotline: 025-51193415
