| abstract | 524,162. Blasting explosives. WILLIAMS, V. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 23, 1939, No. 2321. [Class 9 (ii)] In a process for the manufacture of gelatinous blasting explosives containing nitric esters gelatinised with water-wet nitrocellulose (containing about 35 per cent. by weight of water) the proportion of nitrocellulose used is such that the total quantity of free water in the final composition, if not removed, would substantially exceed 1 per cent. by weight and a dehydrating agent compatible with the explosive in its hydrated form is incorporated so that the proportion of free water in the final composition does not exceed 1 per cent. by weight. Suitable dehydrating agents are vegetable carbonaceous materials such as woodmeal dried to a moisturecontent of from 1 per cent-2 per cent. and hydrated non-deliquescent mineral salts, such as anhydrous sodium sulphate, magnesium sulphate, barium chloride, borax, ammonium oxylate and potassium oxylate. The wet nitrocellulose may be passed through a sieve, mixed with the dehydrating agent and the mixture then treated with the nitric ester or the nitrocellulose and nitric ester may be mixed directly and the dehydrating agent incorporated into the jelly thus formed, any other ingredients then being added. Examples are given in the Specification. Specification 416,586 is referred to. |
