Navutec Co., Ltd. mass-produces large-sized nano heat-strengthened glass.
Chemical tempered glass manufacturing method ion exchange method
A technique to replace the sodium factor in the basic composition of glass with
the potassium factor. Technology in which potassium
dissolved in a strengthening furnace replaces a certain portion of the glass
surface material.
This is a technology in which the potassium factor, which has a large ionic radius and volume, is substituted for sodium, and the free factor on the surface naturally causes a compression effect, causing compressive stress to exist on the surface.
A constant temperature is essential to prevent combustion of other elements in the glass composition, and in the substitution technique, strong surface hardness is maintained by uniform substitution through surface treatment at a certain depth.
Industrial Effect
Transmittance
Improved transmittance
Surface treatment component is replaced from sodium to potassium component
Smoothness
Improved smoothness
Effect of improving bending rate/polarization through vertical manufacturing method
Strength
Increased strength
Strength is improved by about 2 times compared to existing tempered glass (heat strengthened) (10 times that of regular glass)
Reprocessing
Can be reprocessed
Cutting and cutting are possible, resulting in savings in logistics costs and raw materials.
