Wu Siji former Soviet Union -å¡æ•è¯ºå“¥å°”Trask electrical lead zinc conglomerate zinc plant is to replace Cu-Cd precipitation process slag a centrifugal reactor, the production process shown in Figure 1.
Figure 1 Tungstensky-Kaminnogorsk electric zinc plant processing copper cadmium slag production process
The centrifugal reaction separator has a cylindrical shape and a hollow shaft at the center. The shaft is equipped with a special structure separation disc, and the rotation speed of the hollow shaft reaches 3000r/min.
The rate of displacement of the precipitate in the centrifugal reactor was more than 300 times the precipitation rate of the general displacement sedimentation tank, and the productivity per liter volume reached 200 L/h. The low-cadmium cotton obtained in the second-stage centrifugal reactor is dissolved with zinc waste electrolyte, heated to 343K, and the final pH of the reaction is 4.5-5.5, and then purified by KMnO 4 to remove the ruthenium , and then sent to the centrifugal reactor for replacement. cadmium.
Aluminum machining is the use of CNC machining out, including: drilling, boring, cutting, turning, screw. Product material are: aluminum6061,6061-T6,6063,6083,7075.5052,2017 .In the high-speed machining out of the workpiece has a good finish. Aluminum machining product surface treatment has anode, electroplating, sand blasting, laser engraving LOGO, mechanical drawing, rolling flower, according to the requirements of the drawings on the product anode all kinds of colors such as color, black, red, blue, yellow. We have a special inspection department to carry out inspection, to ensure that each size of products meet the requirements of the drawings, machining aluminum(cnc aluminum) is the most common in mechanical processing, low density, not easy deformation, high precision products. So it is widely used in various industries.
