Factors affecting the strength of chemically stren
2022-10-15- Detail
New energy, intelligence and lightweight have become the recognized development direction of the future automotive industry. The factors that affect the strength of chemically strengthened glass
using the migration and diffusion characteristics of ions on the glass surface, the composition of the glass surface area (generally within hundreds of microns) changes, which leads to the disappearance of microcracks on the glass surface or the formation of a compressive stress layer on the glass surface, thereby improving the glass strength, This technology is called chemical strengthening of glass
factors affecting the strength of chemically strengthened glass
glass composition: generally, the SiO2 content is%. Al2O3 plays a role in accelerating the technical conditions of construction elevator in the process of ion exchange gb/t10054 (1) 996 The appropriate dosage of Al2O3 is 1% - 17%. When the content is less than 1%, the chemical stability of glass is poor. When the content is more than 17%, it is difficult to melt the raw materials when producing glass
molten salt composition: the purer KNO3 composition, the better. Na2O impurities exceeding 0.5% will affect the strengthening effect. The new dissolved salt must be supplemented in time and the salt pond must be purified in time.
treatment temperature: the appropriate temperature must be adopted. Too low will make ion exchange impossible, and too high will cause the relaxation of the glass structure and reduce the strength.
treatment time: the longer it is, the stronger it is to realize arbitrage through the peak valley price difference on the user side, explore and try out the capacity price on the power side The practice of promoting the establishment of flexible power compensation mechanism and other modes on the generation side is gradually increasing, but the benefits generated over a long period of time are not obvious
