Abstract
This application relates to the art of pyrotechnics and specifically concerns an improvement in the process for preparing granulated pyrotechnic compositions.
Claims1
A process for producing strong, uniform granules of a pyrotechnic composition consisting of a mixture of at least one inorganic oxidizing agent, an aromatic carboxylic acid salt, water, and optional adjuvants, which comprises:
- (1) mixing approximately 4.0 to 7.0 parts of dextrin, approximately 0.1 to 3.0 parts of guar gum and approximately 8 to 15 parts of water with 100 parts of said pyrotechnic composition, (2) intimately blending the resulting mixture under conditions of at least moderate shear until the granules are relatively uniform in size, and (3) drying the water-wet granules to the desired water content.
