Touchscreen Grade Potassium Nitrate

Optical glass strengthening is to exchange sodium ions on the glass surface with potassium ions in molten potassium nitrate salt, because the radius of potassium ions is larger than that of sodium ions, and potassium ions replace the sodium ions in the glass, causing the surface to "crowd" and expand , forming a compressive stress layer, so as to achieve the purpose of increasing the strength of the glass surface.

Product description

Product introduction

Optical glass strengthening is to exchange sodium ions on the glass surface with potassium ions in molten potassium nitrate salt, because the radius of potassium ions is larger than that of sodium ions, and potassium ions replace the sodium ions in the glass, causing the surface to "crowd" and expand , forming a compressive stress layer, so as to achieve the purpose of increasing the strength of the glass surface. In the process of glass strengthening, 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 the self-developed one-step potassium nitrate production technology to produce high-quality chemically tempered potassium nitrate with a main content of more than 99.9%, extremely low impurities, and sodium, calcium, and iron ions are all lower than 40ppm. Excellent quality and powerful performance can improve salt bath activity, increase strengthening depth, shorten strengthening time, prolong service life, improve flexural strength, surface hardness and other properties, high purity quality, better than other similar products.

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