Method for improving porosity of positive plate

A method for improving the porosity of a positive plate comprises the following steps between a plate coating process and a curing and drying process: a, placing a coated positive unformed plate on a plate conveying roller, sequentially arranging a licker-in, a spraying mechanism and a flattening roller above the plate conveying roller, and distributing hole pricking needles on the licker-in; b, rolling the positive unformed plate by the licker-in, and pressing micropores in the positive unformed plate; c, enabling the positive unformed plate subjected to hole pressing to pass through the spraying mechanism, and evenly spraying a sodium bicarbonate solution with the concentration being 3%-10% to the positive unformed plate through the spraying mechanism; and d, flattening the sprayed positive unformed plate through the flattening roller. Sodium bicarbonate can be ensured to enter the unformed plate, so that the unformed plate reacts in the subsequent curing, drying and formation stages ...
