Zinc alloy products inside polishing wax cause blistering how to improve it

How to improve the electro-galvanized alloy polishing wax cause frothing
Zinc alloy products inside polishing wax cause blistering how to improve it? Nothing less than to proceed from the following three points:
First, the cleaning agent: zinc alloy products require machining before polishing, polishing wax that in addition, there is the oil needs to be cleaned. We currently on the market in addition to wax water except oil ineffective; wax when the blind hole or hole, hole cleaning is not clean angular position. Obviously, zinc alloy wax degreasing cleaning agent selection problem, you should choose efficient, versatile, safe, environmentally friendly zinc alloy wax except oil cleaning agents, such as zinc alloy floating-cleaning wax except oil environmental cleaning agent, in order to thoroughly to remove residual wax and oil;
Second, cleaning equipment: None according to the workpiece oil, wax, shape selected to match cleaning equipment and cleaning agents can not achieve synergies;
Third, the cleaning process: no basis for zinc alloy Molybdenum plate characteristics, the characteristics of the wax, cleaning agents and cleaning equipment optimization of process parameters settings.
From the above analysis we can see that only the cleaning agents, cleaning equipment, cleaning process and choose a suitable match to fully complete the workpiece surface includes blind hole or hole, the hole sharp bit clean. Only pre-treatment been done, then, zinc alloy products will result in blistering internal polishing wax improvement.Thermal shock test The large specimens in a furnace heated to 300 ℃, heat lh, and then quenched in water, the coating may not blistering, peeling separation.
If silver device can withstand the test of the above three methods, indicating that the device is electroplated silver layer adhesion is quite reliable. Of course, there are other testing methods, mainly above four.
