Nitroguanidine Manufacturer & Supplier | Nitroguanidine For Sale

The processes for making weapon and rocket propellants differ in at least one important respect, namely in the number and size of particles produced. Weapon propellant processes are designed to produce a large number of relatively small particles, ranging in size and configuration from small spheres, flakes or cylinders for small arms to very large cylinders, tubes and squares for cannon and mortar loading. Rocket pellets can be much larger. For example, a single particle can be cast and refined in situ in the rocket engine of a tactical or strategic missile or in the propulsion engine for a spacecraft.
Standard propellants for weapons and small rockets are most often made by a solvent extrusion batch process. Procedures vary slightly depending on whether the product is a single, double or triple base propellant. However, a generalized procedure starts with a suitably dehydrated, alcohol-wet NC. If nitroguanidine is to be added for the ternary base, half the required amount is initially mixed with the NC. If the product is a double or triple base, this blended mixture is wetted with a nitroglycerin-acetone solution and then blended again. In the case of a ternary base, the other half of the nitroguanidine is added together with the other components of the formulation. Sufficient solvent is used to make a colloid that will extrude properly. Different processes are performed before extruding. First of all, the colloid must be pressed. Then comes the condensation process. The extruded strips are separated according to their length. Finally, they are coated with graphite and ready.
