1. Improve the surface finish of glass products

Shenhua brand glass compound clarifier introduced the raw materials rich in li20 from Australia. Li20 has the function of good melting aid and improving the brightness of the products. Under the same melting process, the melting speed of the mixture is obviously accelerated, and the melting time is 15-20min shorter than that of other clarifiers, which correspondingly prolongs the time of clarification and homogenization. It also reduces the viscosity of the liquid glass at high temperature, so as to facilitate the clarification and homogenization of the liquid glass The average ratio can improve the melting quality of the glass, thus the surface finish of the glass products can be improved obviously.
