1, the glass in the syrup soak time of 20 to 50 minutes, soak duration of the etching depth and fullness of Bingleng have greater influence on a long time is etched deep and profound Bing Leng, and vice versa shallow and delicate, so according to the Glass performance requirements to determine the soaking time.
2, syrup used for some time, the concentration will be reduced, etching deep enough, may be appropriate to extend the soaking time, If the result is not obvious, we should consider adding ice syrup.
3, syrup used for a period of time will produce some white precipitate should regularly clean up, otherwise it will affect the Bingleng effect, resulting in white edge. Clean-up after the white precipitate produces white edge solutions for the etching liquid to add 2% of the total weight of the water used to dilute the concentration of impurity ions in the liquid, and then add the etching agent; such as etching effect is still good, only a small amount of white border, simply by adding water, no need to add the etchant.
4, add the method for 10% of the total drug add water etching agent stock solution, stir well and make it at room temperature for 2 hours or so aging.
5, using the process of syrup sealed as much as possible in order to reduce evaporation syrup.
