Abstract

The invention discloses a coating metal plate, comprising a base plate, a chemical processing layer on the front face of the base plate, a conductive coating on the back face of the base plate, and a paint layer outside the chemical processing layer, wherein, the side of at least one opposite side of the front face of the coating metal plate is provided with a conductive belt having exposed chemical processing layer. The coating metal plate of the invention is used for processing the shell of the products such as a computer case needing the electromagnetic interference test and the like.

Description

technical field [0001] The invention relates to a coated metal plate, in particular to a coated metal plate used for an electric appliance housing that needs to be tested for electromagnetic interference of the whole machine. Background technique [0002] Existing coated sheet metal, see figure 1 . The existing coated metal sheet includes a base plate 11, and the base plate 11 can be made of steel plates such as cold-rolled plates, electro-galvanized plates, hot-dip galvanized plates, and galvanized plates. A front chemical treatment layer 12 and a back chemical treatment layer 14 are respectively provided on the front and back of the substrate 11 . The outer layer of the front chemical treatment layer 12 has a paint protection layer 13 . The backside chemical treatment layer 14 has a back paint layer 15 on its outer layer. [0003] Because the existing coated metal plate is non-polluting to the environment, it is widely used in the manufacture of shells of household app...
