Chemically Strengthened Glass

Chemically strengthened glass, also known as chemically toughened glass，is a special type of glass that is immersed in molten potassium salts to cause an ion replacement reaction on the glass surface to enhance its strength and scratch resistance. Compared with ordinary annealed glass, chemically strengthened glass shows better impact resistance and temperature difference adaptability, which makes it widely used in construction, automobiles, aerospace and other fields.

Chemical strengthening of glass is a simple and interesting process. It mainly changes the characteristics of ordinary glass through ion exchange on the glass surface, thereby achieving the purpose of strengthening the glass. The following is its main production process:

Before chemical treatment, the cleaned glass needs to be cut to the size we need.

Soak the cut glass in a potassium nitrate salt bath at about 400 ℃ to wait for ion exchange to occur.

The sodium ions on the surface of the glass are replaced with potassium ions in the salt bath. This process usually takes 6 hours or more to complete. The glass is then removed and cooled to room temperature to complete the entire chemical strengthening process.

Chemically strengthened glass is 3 to 8 times stronger than ordinary float glass, allowing it to withstand greater impact.

Chemically strengthened glass has good thermal stability and can withstand temperature changes above 150°C.

As the strength of glass increases, the scratch resistance of chemically strengthened glass has also been significantly improved compared to untreated glass.

Compared with thermally tempered glass, chemically strengthened glass has excellent advantages in maintaining the flatness of the glass surface.

As we all know, thermal tempering is only suitable for tempering flat glass, while chemical strengthening can process glass of various shapes. This makes it play an irreplaceable role in many fields.

Since chemical strengthening requires a long chemical reaction time, its cost is much higher than thermal tempering.

When chemically strengthened glass is damaged, it will break into large sharp pieces, which will increase the chance of human injury, so regular chemically strengthened glass is not safety glass.
