Abstract:
A process of forming a nitrocellulose film on a carrier includes the steps of (i) atomizing a nitrocellulose solution to form a plurality of fine nitrocellulose particles and (ii) evenly spraying the nitrocellulose particles on the carrier to form the nitrocellulose film. The film has a predetermined thickness. The nitrocellulose solution is atomized by an ultrasonic spraying nozzle to control a size of each of the nitrocellulose particles to be sprayed on the carrier. The nebulizer can be air-assisted by inert air to control characteristics of the nitrocellulose spray pattern.
