As we all know, Xinyang perlite by acidic volcanic glassy lava broken pre hotmelt burn is made hydrophobic perlite Kay developed of emulsion explosives physical sensitized material of choice. Perlite main chemical ingredient is SiO2, Al2O3, CaO, Appearance: White porous loose particles, no visible impurities. Kay's invention hydrophobic perlite physical properties of the stable, insoluble in water and organic solvents, slightly soluble in high concentrations of ammonium nitrate solution.
Domestic powdered explosives are divided into expanded ammonium nitrate explosive and modified ammonium nitrate explosives, the two the ammonium oils explosives relative to the old ammonium antimony based explosives has been significantly improved resistance to hardening caking, hot and humid in the south the season anti hardening caking is still widespread, especially coal products.
Perlite, does not participate in the chemical reaction of the explosives, no influence on the oxygen balance of the explosives. The porous structure of a hot-sensitized, improve powder explosive the explosion transfer sensitivity, and to improve the sensitivity of explosives. Mixed with ammonium nitrate, the particles blocking the formation of ammonium nitrate between polymorphs "salt bridge". Can be adjusted by use of expanded perlite, change the the powder explosive compatibility status parameters, improve of powder explosive anti-hardened caking and product performance are to have a positive effect.
