Description
The product represented by this dataset is emulsion matrix, a key intermediate that links upstream and downstream in the industrial explosive industry chain. Its characteristics are high energy, excellent water resistance, and good storage stability (in the unsensitized state). Its upstream key raw materials are basic chemical products (ammonium nitrate, sodium nitrate, fuel oil), and downstream it is used to produce all types of emulsion explosives (such as on-site bulk-mixed emulsion explosives and packaged emulsion explosives). The system boundary of this dataset covers the entire process from the entry of purchased chemical raw materials into the emulsion-matrix preparation area, through aqueous-phase/oil-phase formulation, emulsification, and cooling, until the output of qualified emulsion-matrix semi-finished product. Specifically, it includes the consumption of all main raw and auxiliary materials and energy (electricity, steam) in the above processes, as well as the very small amounts of waste and cleaning wastewater generated in the process. Infrastructure such as the manufacturing of production equipment and the construction of plants is not included within the dataset boundary. The data inventory is formed by merging data from multiple sources.
Activity Description
This data set covers the entire process of preparing emulsion matrix products from chemical raw materials. The main inputs are ammonium nitrate, sodium nitrate, water, fuel oil (such as mineral oil), emulsifiers and a small amount of additives; the main output is emulsion matrix. The main process units include in sequence: water phase preparation (heating and dissolving ammonium nitrate, sodium nitrate, etc. in aqueous solution and keeping warm); oil phase preparation (mixing fuel oil with emulsifier, etc. and keeping warm); high-speed shear emulsification of water phase and oil phase in an emulsification device (such as colloid mill, static mixer) in precise proportions to form a stable water-in-oil emulsion; cooling and temporary storage of the emulsified matrix.
Process Description
Emulsion matrix (also known as emulsion explosive matrix) is a key intermediate semi-finished product in the manufacture of emulsion explosives. It is a water-in-oil (W/O) emulsion system, primarily prepared by subjecting an oxidizer salt aqueous solution (the continuous phase, typically an aqueous solution of ammonium nitrate, sodium nitrate, etc.), fuel oil (the dispersed medium), and emulsifiers (e.g., Span-80) to high-shear emulsification. The product itself is non-cap-sensitive. Its main application is as a raw material, which is converted into various cap-sensitive emulsion explosives through subsequent physical or chemical sensitization processes (e.g., incorporation of glass microspheres or chemical foaming), or alternatively, it can be directly used in on-site mixing and charging truck operations.
