What is a chemical glass tempering furnace? What applications are chemical glass tempering furace?

A glass tempering furnace is a device that can improve the strength of glass. Generally, tempering furnaces are divided into two types based on different tempering methods: physical tempering furnace and chemical glass tempering furnace. The tempering method of physical tempering furnace does not change the chemical composition of glass, but improves the strength of glass from a physical level. Chemical glass tempering furnace improves the strength of glass through chemical means. Below, we will introduce what a chemical tempering furnace is and its application areas.

1. What is a chemical glass tempering furnace

As a type of galss tempering furnace, the main purpose of chemical tempering furnace is to improve the strength of glass. Unlike physical tempering furnace, chemical tempering furnace improves the strength of glass by changing the chemical composition of the glass surface. The main methods used include surface dealkalization, alkali metal ion exchange, etc. This tempering method does not change the physical properties of glass, but only the chemical composition of glass.

Specifically, the tempering principle of chemical tempering is to place glass in molten alkali salt, allowing ions with smaller radii in the surface of the glass to exchange with ions with larger radii in the molten salt, and forming a compressive stress layer on both surfaces of the glass. This compressive stress layer can improve the mechanical strength and impact resistance of the glass.

Tempered glass processed by chemical tempering furnace has high strength, good thermal stability, and is not prone to surface deformation. It also has no self explosion phenomenon and can be cut appropriately. This tempering method overcomes the shortcomings of previous tempering techniques, not only improving the strength of glass, but also not affecting its optical properties.

2. Application fields of chemical glass tempering furnaces

2.1. Electronic product glass

The glass made by using a chemical glass tempering furnace is more suitable for protecting mobile phone screens and protective films, because chemically tempered glass is more sturdy and the mobile phone screen is thin, which is not very suitable for other types of glass.

2.2. Home appliance glass

Chemically tempered glass can be used on the surface of glass in household appliances such as scanner glass, printer glass, cabinet glass, and disinfection cabinet glass.

2.3. Optical glass

Some items require high transparency and strength during use, requiring high optical properties. In this case, chemically tempered glass can be used, such as eyeglass lenses, tempered ultra-thin glass, clock glass, etc. Chemical tempered glass can ensure that they do not experience optical distortion when scratched.

The above is a brief introduction to what chemical glass tempering furnaces are and their application areas, hoping to be helpful to you. The application of chemical glass tempering furnaces is quite extensive, and the glass produced has high performance. Our company can provide you with various glass tempering furnaces.
