The Basic Process Nickel plating is similar to other electroplating processes that employ soluble metal anodes. It requires the passage of direct current between two electrodes that are immersed in a conductive, aqueous solution of nickel salts. The flow of direct current causes one of the
The electroplating process uses an anode and a cathode. In electroplating, the metal dissolved from the anode can be plated onto the cathode. The anode is provided with direct current, oxidizing and dissolving its metal atoms in the electrolyte solution. At the cathode, the dissolved metal ions are decreased and the metal is placed on the product.
S. tanning production. Figure 9.15-1 presents a general flow diagram for the leather tanning and finishing process. Trimming, soaking, fleshing, and unhairing, the first steps of the process, are referred to as the beamhouse operations. Bating, pickling, tanning, wringing, and splitting are referred to as tanyard processes.
A process flow diagram (PFD), also known as a flowsheet, is a type of flowchart used by chemical and process engineers to illustrate high-level processes. You should create your process flow diagram so that it focuses on major plant processes and not show minor details.
A process flow chart is the first step in any process improvement effort. A process flow chart shows graphically how the various inputs, outputs and tasks within a process are related. In order to systematically plan or examine any process, it is necessary to record the series of events and activities, stages and decisions, into a manner which
