NOVELTY - A lead-mud deepening treatment and reuse method involves taking lead paste in thio acid pool for less than 20 hours, collecting in plastic container, collecting lead mud in a curing chamber, performing three-dimensional storage according to certain temperature and humidity of lead chemical substances, water evaporation, two stage of curing, performing three stages of drying, controlling moisture content, followed by carrying out continuous fifth stage curing and crystallization on the lead mud to obtain crystallized lead mud, which is dried, ground, and sieved to obtain lead powder.    USE - Method for deepening treatment and reuse of lead-mud in a storage battery electrode plate coating process.    ADVANTAGE - The method enables utilizing chemical reaction principle between the lead mud and the paste through an acid-base neutralization reaction, converting lead sulfate component in the lead mud to plastic basic lead sulfate, forming reusable lead paste, realizing lead mud recovery and utilization effect, and saving resmelting linkage of the lead mud.    DETAILED DESCRIPTION - A lead-mud deepening treatment and reuse method involves taking lead paste in thio acid pool for less than 20 hours, collecting in plastic container, collecting lead mud in a curing chamber, performing three-dimensional storage according to certain temperature and humidity of lead chemical substances, water evaporation, two stage of curing, performing three stages of drying, controlling moisture content, where the first stage of curing is carried out at 80 degrees C and humidity of 99.9% for 3 hours using steam or atomized water humidification, the second stage of curing is carried out at 85 degrees C and humidity of 99.9% for 3 hours using steam or atomized water humidification, the third stage drying is performed at 80 degrees C and humidity of 0% for 36 hours, the fourth stage drying is performed at 70 degrees C and humidity of 0% for 1 hour by forbidding humidification, the fifth stage drying is performed at 60 degrees C and humidity of 0% for 1 hour by forbidding humidification. The moisture content of the lead mud after curing and drying steps, is more than 5%, followed by carrying out continuous fifth stage curing and crystallization on the lead mud to obtain crystallized lead mud. The crystallized lead mud is dried, ground, and sieved to particle size of 60 meshes to obtain lead powder. The 2% lead mud is added with the lead powder and placed in lead paste coating plate.
