Electrolytic manganese metal present is generally used Pb-Sb-Sn-Ag four yuan together as anode, the anode and the simultaneous analysis of MnO 2 O 2 Analysis of two competing reactions: As can be seen from the figure, both temperature rises φ 2 and φ 1 decrease, and the φ 2 - φ 1 potential difference increases, indicating that high temperature favors the preferential precipitation of MnO 2 . A Rifle Scope sight mounted on top of a rifle that helps improve one's aim by magnifying and pinpointing a target you can increase your fun and skill and accuracy with a long range rifle scope or close combat scope specifically designed for your caliber and target requirements. We have variety of scope reticle types, magnification levels, and range finding reticle patterns available to accommodate hunting, target shooting and tactical combat needs. We have rifle scopes with high magnification for extremely long ranges and low magnification scopes with a wider field of view for tactical close combat shooting. We have scopes for low light shooting conditions and they are high quality rifle scopes featuring fully multi-coated optics for light transmission. Some of our scopes have big objective diameters at the front of the scope for the best light gathering capability in low light conditions. We also offer a large variety of scope mounting options for hunting rifles and tactical rifles. We have a full line of Picatinny Rail systems and two-ring Scope Mounts designed to give you accuracy and handle heavy-duty recoil resistance.

For the electrolytic manganese anode process, it is required to produce MnO 2 (also known as anode mud) as little as possible to reduce the consumption of Mn 2+ and the turbidity of the selected electrolyte, so the application of low temperature, low [SO 4 2- ]T and high Technical conditions such as anode current density are advantageous for metal precipitation.
