Lead-positive electrode mud silver (also known as lead mud) refers to the silver products obtained by electrolytic refining of lead-positive electrolyte containing a certain amount of silver. This product is widely used in the production of lead-containing silver alloy materials. In the process of using lead-positive mud silver, what should be paid attention to?
In general, in the use of lead-positive mud silver, attention should be paid to the following points:
First of all, it is necessary to select reasonable lead mud silver production technology and equip suitable sewage treatment equipment. In the process of lead mud silver production, a large amount of wastewater and other wastes need to be produced, because a large amount of lead ions, sulfide and other heavy metal ions cannot be discharged directly into the environment. Therefore, reasonable selection of lead mud silver production technology, as well as reasonable design and selection of sewage treatment equipment, will help protect the environment and reduce pollution.
In addition, it is also necessary to pay attention to the reasonable proportion of raw materials in the process of making lead-positive mud silver. In general, the lead-positive to silver-containing ratio is usually 1:1, which is conducive to obtaining high-grade lead-positive mud silver products. Of course, the proportion of raw materials needs to be adjusted according to the richness of silver in the electrolyte to achieve the best effect.
Whats more, we should also pay attention to the electrolyte temperature. In the process of producing lead mud silver, the electrolyte temperature will directly affect the reduction efficiency of silver ions and the overall output of silver products. Therefore, in order to increase the output of silver products, the temperature of electrolyte should be controlled. Generally, the electrolyte temperature should be controlled between 20-30℃.
Finally, it is also necessary to control the time in the process of electrolytic refining. If the electrolytic time is too long, silver will be lost due to oxidation and precipitation, resulting in a decrease in silver products. Therefore, how to control the electrolytic time reasonably is also a very important issue.
The above are the matters needing attention in the use of lead-positive mud silver. In order to obtain better lead-positive mud silver products, we must control the raw material proportion, electrolyte temperature, electrolytic time and other production process parameters in strict accordance with the requirements of the production process.
