Product introductionOptical 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 purityOur company adopts the selfdeveloped onestep potassium nitrate production technology to produce highquality chemically tempered potassium nitrate with a main content of more than 999 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 productsWe 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
