The invention discloses a production method of partitioned independent
powder-charged post-dyed graphic
fireworks. A graphic firework structure and a post-dyed graphic firework production method are included. The graphic firework structure comprises lattice structural bodies, the lattice structural bodies are filled with firework base color
powder and connected with simultaneous launchers, the simultaneous launchers are connected with a simultaneous ignition bin, and the simultaneous ignition bin is filled with simultaneous ignition
powder and connected with a lift-off
rocket. The post-dyed graphic firework production method comprises a
dyeing salt solution, a
dyeing device and a
dyeing method, wherein the dyeing method comprises designing graphic sample manuscripts, contacting the dyeing
salt solution with the firework base color powder through the dyeing device, enabling the dyeing
salt solution to permeate into the firework base color powder according to rule limitation, mixing, removing liquid components, performing full
drying, and displaying desired colors after the original firework base color powder is lighted. The production method is simple in implementation and convenient to produce, inventory is not needed, and the graphic
fireworks can be dyed before leaving factories and be dyed by users through free combination after being purchased.
