The hardware weaving chain of exporting auxiliary materials requires environmental protection electroplating. Unclear classification of electroplating. Hope to answer! Thanks!

Environmental protection electroplating = cyanocytic plating? Is it environmentally friendly? Who are those heavy metals in my electroplating fluid to find? Who do I find? Now people's understanding is really avant -garde.
The definition of environmental protection electroplating is currently changing. If the plating that is completely harmless to the human body is environmentally friendly, then there is no environmental protection electroplating, and the standard of ROHS will change. Environmental protection, it is estimated that the role of technical barriers is greater, so it can only be said that it is to develop electroplating systems that are beneficial to human survival as much as possible.
Is for more advanced electroplating, I do n’t know what you mean by high -level, newly developed? Or is the cost higher? In fact, this is not comparable. The application of each electroplating system has his practical significance. Darkro also has his disadvantages, such as poor abrasion resistance, high cost, and he also uses hexavalent chromium. The vacuum has also been plated for decades, and it has less color, but it is environmentally friendly. The current plating process is relatively mature and the cost is stable, and it is impossible to comprehensively replace it at all.
For the classification of electroplating, it is generally divided by plating, such as galvanizing, nickel plating, chrome plating, etc., and there are also categories according to application, such as wheel electroplating, plastic plating, PCB electroplating plating, PCB plating plating and many more.
The electroplating is a method of surface treatment. There are many other methods, such as heat plating, chemical plating, electrical casting, physical deposition, anode oxidation, etc. Strictly speaking, vacuum plating does not belong to Plating category. LZ, let's look at related books. There is also that hexavalent chromium is not environmental protection is not because it does not meet the ROHS standard, and ROHS is also set by people. It is a tool for being used.
The last wishes that the host is smooth. I don't know which one you are plating? Is it silver or gold for jewelry? Those who try to find the acid system as much as possible, avoid cyanide, and use triple valence; if it is galvanized, it is similar.
Environmental electroplating is cyanide -free electroplating.
The alkaline -free copper -free copper -plated process developed in 2003 has a leading domestic level. To obtain mirror gloss on the electroplating of iron, copper, and copper alloy matrix, it can shorten the total time of electroplating; the coordination force of the plating layer is good, without pinch, no crispyness; Primer. As a result, the toxic cyanide copper plating is effectively replaced.
It has been developed one after another u003Csupporting hanging plating>, steel pieces without cyanoptin, copper -soaked tin u003Ccan replace copper plating direct nickel plating>, cyanomy -free salt and other series of environmental protection products And all have been successfully pushed to the market.
The chromium -plated chromium, three -valent chromium is environmentally friendly, but hexavalent chromium is not because it cannot meet the requirements of ROHS. You just said that the more advanced plating than environmentally friendly electroplating is vacuum electroplating.
1. Electroplating and environmentally friendly nickel is soaked in chemical ingredients. It has the advantages of not deforming the product.
2. The ordinary electroplating method is divided into plating and rolling plating. The possibility of deformation of the product.
The upstairs are good, but there are some one -sided, cyanide -free electroplating is one aspect, and environmental protection is also required in post -treatment. Secondly, it cannot contain trace prohibited metals in the electroplating layer, such as lead, mercury, hexavalent chromium, and so on.
The is better than environmentally friendly plating, Darklo processing, vacuum electroplating, etc., but these processing methods are costly!
Environmental electroplating generally refers to the requirements of the electroplating product to meet the requirements of ROHS. More environmentally friendly than hydration is vacuum -plated!
