Small investment for e SZ-HGL Coating Chemical Furnace is professional for tempering thin glass with perfect flatness. I. Chemical toughened glass As some special glass can not be physically toughened, such as thin glass thickness less than 2mm, Hyperboloid bent glass for express train, big bus, etc, or strict flatness re for glass, for example special glass for copier, these special glass must be chemically toughened. The the theory of chemical toughening, At a certain temperature, make the bigger metallic ions( such as K ions) exchange the smaller Na ions in the glass surface, the stress will be formed on the glass surface when glass cools down, thereby the strength of glass is increased.
