Ammonium nitrate 65 Water 2.5
Mannitol nitrate 0.25 4
2.5 carboxamide foam stabilizer (N- dodecyl -β- propanol sodium salt of iminodiacetic ) 0.25
Aluminum powder ( atomized , where 72% +325 mesh, 28% -325 mesh ) 25 thickener 1.2
Preparation and dosage formulations described above , the sodium nitrate , 20g of ammonium nitrate , formamide , water and mannitol with a steam jacketed mixer impeller and heated to 92 ℃, then add 25g of crushed explosive grade ammonium nitrate particles ( 53% of +100 mesh, 47% -100 mesh ) to make starting material 36r/min speed mixer mixing the drug , the mixture was heated to 93 ~ 98 ℃, become crushed spice nitrate solution dilute slurry. Aluminum slurry was added further , followed by stirring at the speed 18r/min, 1-fold speed increase financial stirred 1min, break the mixture clumps. Drug material held in 93 ~ 98 ℃, and then stirred at 12r/min adding additional pieces 20g ammonium nitrate . Mixing was continued at 93 ℃, spices until softened thick uniform slurry , heating was stopped , was added with stirring at 12r/min 30s. In 18r/min speed thickener was added with stirring (0.2g Gul gum , 0.2g Gul partially crosslinked rubber is dispersed in 0.8g of ethylene glycol ) , mixed 30s. Then the slurry was mixed under 24r/min make hydrated gel , the hold signal coming foam stabilizer clip bubbles . The final slurry was maintained at 91 ℃. Filled with a slurry in the vessel was cooled , the salt was dissolved in a sufficient amount of precipitated out of solution . Into a solid . Curing temperature of about 71 ℃. The explosive in the case of the presence of a sufficient amount of hot water , the ingredients were mixed together and made of cast explosive mixture of the drug is called legal .
