Gelled chromium acetate cross-linked aqueous slurry type salt explosives, and manufacture
Gelled aqueous slurry salt type explosives are described in which the gelation agent is guar gum crosslinked with a chromium acetate at pH levels lower than heretofore, viz, at 4.5 to 5.4. Crosslinking the guar gum in this pH range is accomplished with a chromium acetate of the group of chromium hydroxy acetate, chromium triacetate, and mixtures thereof, in the presence of calcium nitrate, which constitutes at least part of the oxidizer salt. Heretofore, guar gum/chromium acetate gelation agents for the above explosives have been available only at higher pH levels with accompanying impairment of gel strength and stability, water resistance, viscosity characteristics, and stability of certain ingredients of the explosive.
