Claims17
A process for producing double base casting powder, comprising:
- mixing ethanol-wet nitrocellulose and additives to form an ethanol-wet nitrocellulose mixture with additives;
- adding to the ethanol-wet nitrocellulose mixture with additives, a nitroglycerine solution comprising nitroglycerine and 2-NDPA dissolved in acetone and further mixing to form a nitroglycerine mixture;
- adding ethanol to the nitroglycerine mixture and further mixing to form a nitroglycerine mixture with increased ethanol content;
- adding ethanol and diethyl ether to the nitroglycerine mixture with increased ethanol content to from a resultant mixture;
- and
- post-processing the resultant mixture to form the double base casting powder.
