Title: Innovations of Yongquan Ma in Lead Oxide Recycling
Introduction
Yongquan Ma is a notable inventor based in Changxing, China, recognized for his contributions to the field of recycling lead oxide-containing materials. With a total of two patents to his name, he has developed innovative methods that significantly enhance the efficiency and sustainability of lead recovery processes.
Latest Patents
Yongquan Ma's latest patents include a method for recycling lead oxide-containing waste material. This method involves several steps: first, the lead oxide-containing waste material is contacted with a desulphurizer under specific reaction conditions, followed by solid-liquid separation to obtain a filtrate and filtration residue. The filtration residue is then subjected to a conversion reaction at temperatures between 350-750°C to convert lead-containing components into lead oxide. The product is subsequently treated with an alkaline solution to dissolve the PbO, leading to the crystallization of PbO crystals. This innovative approach not only reduces energy consumption but also improves the overall efficiency of the recycling process.
Another significant patent by Yongquan Ma is a method for directly recovering lead oxide used for lead-acid battery cathodes from waste lead paste. This method also involves contacting waste lead paste with a barium-containing desulphurizer and performing solid-liquid separation. The filtration residue undergoes a conversion reaction at similar temperatures to convert lead components into lead oxide. This method effectively achieves the direct recovery of lead oxide raw material, significantly decreasing recovery costs and energy consumption while enhancing the comprehensive utilization of waste lead paste.
