| 简介 |
The invention concerns a method for dry process manufacturing of pyrotechnical objects from at least one reducing filler selected among guanidine derivatives, metal hydrides, alkaline or alkaline-earth metal hydrides and at least one oxidizing filler selected among alkaline metal nitrates, alkaline-earth metal nitrates of basic metals; at least one of said reducing and oxidizing filler(s) having creeping property. Said method enables pellets and small balls to be directly obtained by compacting/compression; granules, useable as such, to be obtained by compacting followed by granulation; compressed objects to be obtained by compacting, granulating followed by compression. The invention also concerns the resulting efficient pyrotechnical objects. |
