Abstract:

A cure mechanism of Fluid Ball powder and triethylene glycoldinitrate was conducted. The objective was to determine if all the ball powder was completely dissolved during the current process or if most of the cure was by gelation. Experimental results showed that ball powder spheres were discrete after normal cure time and temperature. Fluid Ball powder will completely dissolve in triethylene glycoldinitrate if the powder is made from low nitration level nitrocellulose.Penetration of plasticizer and cure rate increase with temperature. Powder particles can be observed as round and oval objects in cured propellant compositions by microscopy and radiography. Cure mechanism is by gelation and swelling of Fluid Ball powder by the plasticizer with a small amount of the powder spheres being completely dissolved. Author
