Abstract

"MéTODO DE PREPARAR UM EXPLOSIVO SENSIBILIZADO". A presente invenção refere-se a um método de preparar um explosivo sensibilizado compreendendo as etapas de fornecer termicamente microesferas expansíveis que, quando expandidas, são adequadas para reduzir a densidade de um explosivo e misturar as microesferas com vapor para causar expansão térmica das microesferas e para fornecer um fluxo resultante de microesferas expandidas úmidas. O fluxo resultante de microesferas expandidas úmidas é então introduzido em um explosivo para fornecer um explosivo sensibilizado.
