There are many ways in which the surface of a metal material can be treated industrially, and the processing techniques covered therein are physical, chemical, and the like. Industrial keyboards are also made of stainless steel, so here’s a quick overview of how to handle industrial keyboard surfaces.
1 Dacromet way
Taking the panel of the industrial keyboard as an example, the Dacromet method is made by immersing the chemical substance of zinc chrome film with the industrial keyboard panel, and then placing the industrial keyboard panel in a heating furnace for baking. The furnace usually maintains about 300. The temperature is grilled for one hour until the surface of the industrial keyboard forms Dacromet (another name for zinc-chromium film). In this way, even in the future, even if it is corrosive, it will not directly corrode the surface of the industrial keyboard, and this layer of Dacromet also plays an important role in the oxidation resistance.
2 Mechanical method
Taking the buttons of the industrial keyboard as an example, the buttons of the mechanical degree are placed in the drum, and the metal particle material, the medium and the water are mixed together, and the roller is operated at a high speed for about 60 minutes until the surface of the button is pressed. The zinc plating layer is formed, so that the surface of the button can be protected, and the surface of the button can be made metallic and the hand feels better.
3 Plating method
Taking the panel of the industrial keyboard as an example, this method is relatively mild, and only the industrial keyboard panel needs to be placed in the electric solution. After the power is turned on, the surface metal of the panel and the mineral element of the electric solution are chemically reacted, and finally the metal formed on the surface of the panel is formed. A protective film containing an alloy of copper, zinc, nickel, or the like. However, the plating method reduces the strength of the industrial keyboard panel in part because the hydrogen embrittlement in the plating method causes a decrease in strength. The above are the surface treatment methods of three common industrial keyboards, each of which achieves a long life effect. If the work intensity is ranked, the Dacromet method is the best and the plating method is second.
