摘要

We have now found that associative thickeners may be used in emulsions for use in explosive compositions, which associative thickeners provide for rapid and reversible changes in emulsion viscosity. Associative thickeners provide explosives emulsions having the desirable characteristics of (1) significant reduction in viscosity during pumping and (2) reestablishment of relatively high viscosity when pumping is terminated without damage to the emulsion components. It is believed that the associative thickener provides a network of physical linkages throughout the emulsion which network can be reversibly broken down.
