Optical glass strengthening is to exchange sodium ions on the glass surface with potassium ions in potassium nitrate molten salt. Because the radius of potassium ions is larger than that of sodium ions, potassium ions replace the sodium ions in the glass, causing the surface to'crowded' and expand. , Forming a compressive stress layer, so as to achieve the purpose of increasing the strength of the glass surface. In the glass strengthening process, the purity of potassium nitrate has a great influence on ion exchange. If the purity of potassium nitrate is not enough, there will be more impurities such as sodium, calcium and money. It will interfere with potassium and sodium ion exchange and affect the glass strengthening effect. Therefore, potassium nitrate for optical glass requires very high purity.

Our company adopts self-developed one-step potassium nitrate production technology to produce high-quality chemically toughened potassium nitrate, the main content of which is over 99.9%, the impurities are extremely low, and sodium, calcium, and iron ions are all less than 40ppm. Excellent quality and powerful performance can improve the salt bath activity, increase the depth of strengthening, shorten the strengthening time, extend the service life, improve the flexural strength, surface hardness and other properties. The high-purity quality is better than other similar products.

We can provide glass strengthening technology solutions, according to the glass reading brand, composition, thickness recommended temperature, time and different accelerators and protective agents, according to different brands of glass to provide corresponding composite strengthening solutions to ensure good quality and long furnace life.
