Which electrode and lining are selected for electroplating wastewater?
Electroplating wastewater is a very complex medium.How to choose the flow meter?The electromagnetic flow meter is preferred because of its conductivity, high accuracy and reliable performance.So how do I choose electrodes and linings?
First of all, we need to know what electroplating wastewater is. The composition of electroplating wastewater is very complex. Except for the wastewater containing cyanide (CN-) and acid-base wastewater, heavy metal wastewater is a potentially hazardous wastewater category in the electroplating industry.Classify them according to heavy metal elements contained in heavy metal wastewater, it can be generally divided into chromium (Cr) wastewater, nickel (Ni) wastewater, cadmium (Cd) wastewater, copper (Cu) wastewater, and zinc (Zn) wastewater. , gold (Au) wastewater, silver (Ag) wastewater, etc.In general, water is acidic and a small amount is alkaline,and the heavy metal content varies with surfactants, brighteners, and production processes.In other words, it is unstable.
First,we can choose polytetrafluoroethylene (PTFE) as the lining of the electromagnetic flow meter.Because of its excellent corrosion resistance and heat resistance,, it can resist almost all chemical media, including concentrated nitric acid and aqua regia.Secondly,for the choice of electrodes, tantalum (Ta) electrodes can be selected because of its strong corrosion resistance, which can withstand the corrosion of almost all chemical media except hydrofluoric acid.
The HHD electromagnetic flow meter developed by Huahai is a kind of inductive instrument that measures the volume flow of conductive medium in the pipe according to Faraday's law of electromagnetic induction. It adopts the embedded technology of single chip microcomputer to realize digital excitation,and adopts CAN field bus in electromagnetic flow meter. It is the first in China and its technology has reached the domestic leading level.

</a> Commonality simply meant that the three F-35 variants would share portions of high-cost components like the airframe, the avionics, and the engines. This was supposed to help ensure that the plane was âaffordableââa term that the company and Defense Department managers invoked with the frequency of a Vajrayana chant. But commonality did not really come to pass. The original plan was that about 70 percent of all the parts on the airplanes would be common; the actual figure today is about 25 percent. Commonality, even at this reduced level, has unintended consequences. When a crack in a low-pressure turbine blade was discovered in an air-force F-35A engine earlier this year, Pentagon officials took the only responsible course, given that the part is used in all models: they grounded the entire fleet of F-35s, not just the ones flown by the air force. In his June testimony, the Pentagonâs Dr. Gilmore revealed another, less public grounding of the entire F-35 test fleet, which occurred in March 2013 after the discovery of âexcessive wear on the rudder hinge attachments.â
