Glass surface technology chemical reinforcement ( Toughened)

Chemical reinforcement ( Toughened)

to ion exchange process is also called chemical glass surface strengthening, the commonly used method is molten salt method and spray method.

molten salt method. To solute in the small radius of ion exchange in the glass radius of ions, or small to solute the radius of ion radius of ion in the glass, the glass surface compressive stress, to raise resistance to internal pressure strength, high hardness of the processed products. Wear resistance, the strength of the products will not be reduced because of long time using.

spraying method. Spraying chemical tempered with enhancement effect is good, the production and use of safety, high efficiency and low cost of production, from the perspective of comprehensive evaluation on the analysis, can yet be regarded as a kind of ideal enhancement technology at present.

in order to improve the effect of spraying chemical tempered and adaptation and technology features, studies should choose ideal glass chemical composition, the basis of basic glass chemical composition, spraying, spraying liquid additive formula also should make corresponding adjustment;

spraying chemical tempered in every process, will important influence on its final enhancement effect, therefore, must grasp two stages of the process parameters: the first stage, the formation of the solid phase reagent layer must be good control of spray temperature, solution concentration, spray time, spray droplet size, the thickness of the solid phase reagent layer, density and other parameters; The second phase, heat treatment, Ion diffusion and exchange) Must control the temperature. The method can make the strength of glass containers has reached around 2 times the original value, enhanced products in the transportation and machinery in the process of filling the original value of the loss is reduced to about 13, through spraying chemical tempered glass has the very good gloss and commodity appearance.
