The glass is one of the delicate material that can be easily broken it couldn’t handle the pressure so several types of glass can be used for strengthening purpose. Thermal glass tempering and Chemical Strengthening are two primary methods for increasing the strength and durability of all glass based materials. Let’s have a quick comparative view of these two processes
Let’s talk about Chemical strengthening first. This is an ideal approach where optical distortion should be kept the minimum. Chemical strengthening process would harden soda lime and other glass surfaces. Such type of process has higher strength and durability. It is also maintaining higher surface quality which is approximate 80/50 and up to 60/40 for lower applications. Chemical Strengthening can create high-quality glass with minimum distortion. Chemical strengthening has to implement on thinner glass than conventional heat tempering. If we talk about its benefit that includes an extensive range of property that would suit best. The chemically strengthening process is robust and can be utilized in harsh environments.
Thermal Glass tempering has the same functionality like technical ceramics chemical strengthening. There would be variation in the tension levels of several layers of glass. Tempering process superheats the glass, but it will quickly cool down the glass. When it is heated glass expands, and with the rapid cool down I will contract with the same speed. Such type of process is quite commonly being utilized in high pressure and high temperature in diverse industrial environments. Get to know this point that core of the glass would retain heat for a long period.
These two processes are being widely used in each everything whether you take household items or aerospace applications as well.
