TH1100B - Stabilized ammonium nitrate or stabilized product with high ammonium nitrate content And how to produce these products - Google Patents

Abstract

This invention involves ammonium nitrate or products with high ammonium nitrate content. Both of these substances have been Stabilization against blistering and disintegration when received Changes in temperature and is related to this method of production include porous particles with a surface area of 150-400 square meters per gram. and a pore size of 100-300 angstrom into the product at a rate of 0.05-1.0% wt. For the particles it is proposed to use silicon dioxide particles. Porous species with a surface area of 250-350 square meters per gram. and has a pore size of 100-250 Angstroms. This product is made by Start by drying the ammonium nitrate or products with high ammonium nitrate content, granules or granules. Then coat them with porous particles. and may also be added with a dust fixing agent and/or anti-caking agent. Such modified ammonium nitrate is characterized by both Stable and porous as required for use in making explosives appropriately, and in addition, it has the so-called eye properties. that the substances used in the tropics must contain fertilizers High ammonium nitrate is made according to this method of invention. There will be a number of better coagulation. and tend to Less dust is produced because the water contained in it is fixed in the hole. the porosity of the pretreatment
