Problems solved by technology

[0002] The main components of existing emulsion explosives include ammonium nitrate and sodium nitrate. However, the addition of sodium nitrate makes the production cost of emulsion explosives remain high due to the high price on the one hand, and the labor load of workers is also relatively large.
