(3) The process of melting lead, casting plate and lead parts in the production process of lead batteries should be carried out in a closed workshop, the parts that produce smoke should be equipped with local negative pressure facilities, and the collected waste gas will enter the waste gas treatment facilities. Depending on the type of product, the gravitation casting grid manufacturing technology of continuous casting and rolling, continuous punching, drawing, die casting or centralized lead supply (referring to the use of one lead melting furnace to supply lead to more than two casting machines) should be used. The preparation and melting process of lead alloys encourages the use of lead slag reducer to reduce the amount of lead slag produced.

(4) The lead powder manufacturing process should use fully automatic sealed lead powder machine; The paste process (including feeding) should use automated equipment and be produced in a closed state; Coating plate and plate transfer process should be equipped with waste liquid automatic collection system; The production of tubular plates should use automatic paste extruder or closed automatic negative pressure powder filling machine.

(5) The sub-plate and brush plate (ear) process should be located in a closed workshop, using mechanical sub-plate and brush plate (ear) equipment to maintain production under local negative pressure conditions; The packaging, weighing, assembly and welding processes are encouraged to use automated equipment, and maintain production under local negative pressure conditions, and encourage the use of lead-free solder.

(6) The acid supply process shall adopt automatic acid dispensing, closed acid conveying and automatic acid irrigation; Automatic liquid waste collection systems should be equipped for recovery or disposal.
