With the continuous development of modern technology, most of the products have greatly improved, and now Dacromet metal coating has become a new type of anti-corrosion coating that people like very much. Now let's talk about how to distinguish dacromet coating True and false.
First, the selection of good flake zinc powder, is to obtain a good Dacromet coating an important condition. It is at this point that there is a problem with fake Dacromet.
Second, the observation method: Because dacromet coating solution selected zinc, is quite small, non-naked eye can directly see clearly. Therefore, in order to confirm the actual situation of the zinc powder used, we must use tools to analyze and judge. You can use the microscope to observe, do not have to use a microscope with a large magnification, as long as you can see clearly on it. By looking at the washed zinc sinking in the bottom of the cup, you can learn about the choice of coating zinc in the details. Made of flake zinc powder, made, due to the performance of the import is not good, if more solid, large diameter film, or post-processing is not done, will also be observed in the use of water washing, the precipitation soon appeared, The use of this powder for dacromet is not satisfactory and the coating made with this powder is of poorer quality, but such flake powder can be used in other aqueous coatings.
The above is the method of identifying dacromet coating, I hope everyone can grasp, so next time you buy dacromet coating will not be cheated when the problem. Dacromet metal coating effect will be better. Although dacromet paint has many advantages, but some dacromet also contains chromium ions that endanger the human body, so we must also pay attention to use.
