The invention discloses a plate
drying process, which comprises the following steps of: when plates are grooved, uniformly loosening the negative plates piece by piece, directly placing the negative plates on a
steel frame, and placing the whole
steel frame in a pure water tank; after the grooving of the negative plates is finished, hoisting all the negative plates on the frame to a
pool by using a traveling crane, and rinsing the negative plates from top down by using
tap water, wherein supplied water and discharged water form
counter current, and a pH value of the plate rinsing water is 5 to 7; after the rinsing is finished, feeding the plates into a
boric acid pool, and impregnating the plates by using
boric acid solution with the density of 1.025 to 1.045 g / cm<3> at 65 DEG C for 15 to 20 minutes; after the
boric acid impregnation is finished, placing all the plates on the frame below an axial flow fan blowing air from top to down, and performing air blowing for 30 to 60 minutes in summer and 45 to 90 minutes in winter; and after the air-
drying is finished, placing the plates into a Zhongnan
drying kiln and performing drying for 40 minutes, wherein the temperatures of three drying stages are 160 DEG C, 150 DEG C and 120 DEG C respectively. The process provided by the invention is used for treating the negative plates, increases the
lead metal content of the negative plates, avoids the pates being oxidized in storage and reduces the labor intensity of workers in the plate drying process.
