Description

technical field [0001] The invention relates to an emulsion matrix stability detection device, which is used for the emulsion matrix stability detection of emulsion explosives. Background technique [0002] Since the patented technology of emulsion explosives invented by American H.F Bloom in the 1960s, due to the excellent water resistance and explosive performance of the explosives, it has concentrated the advantages of ammonium oil explosives, slurry explosives, and water-gel explosives. attention from all countries. The emulsification process is an important link in the production of emulsion explosives. In the production process of emulsion explosives, the quality of the emulsified matrix directly determines the quality of the emulsion explosives. The emulsifying matrix belongs to the category of emulsion, and emulsion is a thermodynamically unstable system. The aqueous phase of the emulsification matrix has a tendency to crystallize, and the resulting crystal growth ...
