How is the surface of the stainless steel filter treated?

The reason why the etching filter is named is mainly because of this special production process, the stainless steel sheet is chemically etched to obtain the ambition of the pattern or the mesh. It has: the mesh is round, evenly placed, and the filtering effect is uniform. In addition to the extensive use of the etching filter in the filtering profession, the electronic profession also uses the process to carry out data.

Planning and messy columnars to machine bumpy metal products. It is widely used in integrated circuit printing, fluorescent screen electronic grid, accurate filtering, micro-electrode components and so on. No matter what kind of occupation is used, the appearance of the etched net is always a special light. There are three ways to deal with the appearance first.

Appearance whitening treatment; fine etching products in the process of processing, through the coiling, burring, welding or through the artificial appearance of fire baking treatment, black scale. This sturdy gray-black oxide scale is primarily composed of two EO4 components, NiCr2O4 and NiF, which were once removed by strong corrosion using hydrofluoric acid and nitric acid. However, this method is costly, pollutes the environment, is harmful to the human body, and is highly corrosive, and is gradually being screened.

     External mirror finish treatment; depending on the level of clutter of the fine etching product and the user's requirements, mechanical polishing, chemical polishing, electrochemical polishing, etc. can be used to achieve the specular gloss. This is a kind of external treatment that uses more than ***. In addition to the brightness of the exterior, it is also possible to perform exterior coloring.

     Fine etching products not only impart various colors to finely etched products, but also add a variety of fine etching products, and improve the wear resistance and corrosion resistance of the products. Used to make exquisite artwork, household items, and decorations.
