Abstract

522,989. Explosives. WILLIAMS, V. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 22, 1938, No. 37340. [Class 9 (ii)] In a method of producing a low-density blasting explosive free from self-explosive sensitizers such as nitric esters or aromatic nitro-compounds, ammonium nitrate is incorporated in the presence of water with a lowdensity woodmeal or pithmeal obtained by comminuting a low-density wood or pith having in the undisintegrated state a bulk density not exceeding 0.25 gram per cc. so that the ammonium nitrate is at least partly impregnated into the carbonaceous material and the mixture after being dried at a raised temperature to a moisture content not exceeding 2 per cent. is granulated so that the particles will pass through a sieve having apertures of about 0.11 inch square. Balsa wood, bongo wood, bagasse, megasse or cornstick pith may be used for the production of the meal. The mixture is carried out at a raised temperature not exceeding 120‹C. and other ingredients such as cooling or flame quenching' materials may be. included. Granulation may be effected while in paste form or the material may be allowed to set and is then broken up mechanically. It is packed at a low pressure into thin tin-plate or waterproof containers and in boreholes 'not exceeding two inches diameter, the composition can be initiated by a No. 7 detonator without an additional primer.
