Galvanized sealer
Galvanized sealer is a water-soluble sealer, used with water, easy to operate, low cost, does not contain silicate and resin, environmentally friendly and non-toxic, the protective film is easy to remove, and is easy to use. The processed workpiece can form a dense protective film with strong resistance to salt spray (neutral salt spray test can last up to 1 hour).
Operating process
Open the cylinder with pure water, concentration %
Temperature ℃
Soak for seconds, dry slightly and then dry directly (strongly recommended not to wash with water)
Dry Temperature ℃
. The time is about minutes
Operation process: electroplating, water washing, passivation, sealing and drying (don’t wash, just shake it lightly, you can also drip dry) drying and packaging
(Pay attention to the color of the blue zinc and colored zinc after sealing It will turn white and yellow respectively. In order to achieve a better color, it is recommended to dry it and then seal it.)
Note that the concentration is %. If it is too low, color spots will appear and the ability to resist salt spray will decrease. If the concentration is too high, White rust is prone to appear in the salt spray test (white rust is also prone to occur if the sealer film is not completely cured). The curing time of the sealing film is hours. Therefore, in order to achieve the best salt resistance, salt spray should be applied after hours of drying. test. It is recommended to use it on small workpieces. It is not recommended to be used on large workpieces. White spots may appear when used on large workpieces. Please use with caution.
Fault phenomenon and solution
Fault phenomenon
Cause analysis
Solution
The salt spray time is too short, or the workpiece has colored spots.
The concentration is too low
Add appropriately, but not more than %, otherwise the workpiece will turn white after two or three days.
There are white spots or white patches on the surface of the workpiece.
It has been used for too long. Too much, or contaminated. The workpiece liquid becomes cloudy and corroded, or there are white patches on the edge of the melter.
Replace the workpiece fluid, clean the white liquid on the container, and restart the cylinder.
There are spots on the surface of the plated parts
There are sediments in the workpiece fluid
Replace or filter the working fluid
The color is normal on the first day, but the color turns white after a few days,
Concentration Too high, the value is low and the temperature is low
Reduce the temperature to %, (use analytical pure or chemically pure ammonia to increase the temperature to ℃
There is whitening after the salt spray test
The air drying temperature is too high, The workpiece is not completely cured
The temperature should be lowered to below ℃, and the salt spray test should be performed an hour after the workpiece is processed.
If the requirements for salt spray resistance are particularly high, it is recommended to operate according to the following method
After sealing The workpiece is first air-dried at a temperature of about ℃, and then kept at a temperature below ℃ for minutes.
Attached is the concentration detection method.
Please use a hydrometer when grooving, record the value, and test at least once a day. When adding Just add according to the specific gravity count value when grooving. The hydrometer value generally reaches this range by increasing or decreasing the concentration. When it exceeds the hydrometer value, please add pure water. If it is below, please add pure water. It is recommended to control it within the ideal range. .
Packing kg/barrel
In addition, it is specially stated that this product is environmentally friendly and non-toxic, but the hexavalent chromium will exceed the standard when tested by the boiling method. This is because this product will cause chromium to be dissolved under the conditions of the boiling method. The valent chromium is reduced to hexavalent chromium. If the customer requires the boiling method to detect the hexavalent chromium content, please use it with caution
