بررسی فرآیند ریخته‌گری مذاب مواد منفجره حاوی تری نیتروتولوئن TNT(علمی-ترویجی)
Authors
Abstract:
In this article charging of explosives through casting has been investigated. Melt casting of TNT-based explosives is one of the most common techniques to economic and mass production of explosives. TNT is the only molten explosive at low temperature (80.4 C), so it is a convenient matrix for casting. Shrinkage of TNT in amount of 11-12% during solidification causes some problems in melt casting. In this article a description of different aspects of melt casting including material, common formulations, Meisner process, numerical simulation and comparison of advantages and disadvantages have been discussed. Studies show that the melt casting is a simple and feasible technique which can be safely used at industrial scale.

The purpose of this paper is to review the effect of polymer additives on the final viscosity of PBX slurry and viscosity reduction mechanism. Variables related to the formulation and manufacturing process affects PBX viscosity. PBX viscosity directly affects the process of mixing and charging of these materials and hence it is necessary that the viscosity values to be low in order to facilitat...

Plastic Bonded Explosives with inert binder despite having good mechanical properties and low sensitivity, because of containing inert materials, have low energy level. So investigations for replacing inert binder system with energetic binder system and high exploding components in the making of these materials are performing. It seems using energetic polymers and materials like Cyclotetramethy...
