1. Cleaning of etching partsAfter the etching is completed, the etching parts should be washed in time. If necessary, use the diluted neutralization solution to neutralize it, because the etching solution is a very corrosive liquid. If it is residual on the surface of the etching workpiece, it will

1. Oil on the surfaceAfter the metal workpiece is processed, transported, and inventory, the surface is stained with different processing oil or rust -proof oil, etc., and it must be completely cleaned. Not good, the paint film is soaked in the etching solution to bubble or break, causing the surfac

In November, Hot Sales, 240 pcs etching zinc plates are packed for delivering to our customer in Nigeria. High quality zinc etching plates with good packaging.Galvanized plate refers to a steel plate plated with a layer of zinc. Galvanizing is an economical and useful anti -corrosion method adopted.

Improve the uniformity of the etch rate across the board surfaceThe etching uniformity of the upper and lower sides of the board and each part of the board is determined by the uniformity of the etchant flow on the board surface. During the etching process, the etching rates of the upper and lower p

In the chemical etching process method, the parts or parts that have been coated with a graphic anti-corrosion layer are placed in the corrosive solution for corrosion, and the corrosion is continued until the metal thickness reaches the requirements or the graphic depth reaches the requirements. In

After etching, the product is the original color of the metal, and many require subsequent surface coloring treatment: surface color whitening treatment; surface mirror bright treatment; surface coloring treatment. 1. Surface whitening treatment: During the processing of precision etched products,

Etching of metal products, whether it is copper, aluminum, stainless steel, nickel sheets,etc. after the material manufacturer produces metal materials, some will apply a layer of anti-rust oil on the surface, and some will only attach a layer of protective film to the surface. The surface of the pr

Before metal etching plates become exquisite handicrafts, they all need to undergo precise processing technology, so how are metal plates etched?1. Inspection of metal materials:When the metal plate of the raw material needs to be etched, it must be inspected first, that is, the work we need to do i
