This is due to the difference in polishing and plating process produced by the product grade.
When it comes to sealing oil, there is also a name for “ratchet”. It is another layer of protection outside the electroplating. It can separate the direct contact between the coating and the outside world, greatly improving the safety of the coating.
How to identify the sealing oil of a hardware accessory? First, look at the degree of reflection on the surface of hardware accessories. For example: the difference between the mobile phone before and after the film. That should give you some idea. Of course, only such a method of identification is unscientific and incomplete. Not all of my friends know about this kind of technology, so it’s very abstract. 2. See whether small oil droplets are found on the lower edge of the product. Another example, in the morning, the small drops of water on the leaves, where low to where the flow of the same truth. After sealing the oil, when drying, there will always be excess oil flow to the lower ed
