In the phlegmatisation of crystalline explosives, e.g. octagen, hexagon or PETN, or combinations with partic. non-explosives, e.g. powdered Al, by wet granulation with water, a minor proportion of the phlegmatisation or binder agent is replaced by oxazolin wax. The wax is dissolved in a solvent (e.g. trichloroethane or methyl chloroform) and agitated with the granulation suspension at which time the solvent is driven off. This causes the wax to be deposited on the particle surfaces before the phlegmatisation agent proper or the binder is added and deposited by continued agitation and temp. regulation of the suspension. Pref. amt. of oxazolin wax is 0.01-0.1% on wt. of solid particulates. Process is also useful before coating with plastics binders. |
