    Hollow Glass Microspheres HN20

    Thin-walled hollow glass beads from sodium borosilicate material with a special process, closed the tiny sphere, the sphere inside the parcel certain amount of gas, its specific density, low thermal conductivity, low oil absorption, particle size and chemical composition controllable superior performance, which makes it very suitable as emulsion explosives sensitizers.

    Density modifier:When filling 2%- 4% of microspheres (mass ratio), it can effectively regulate the product’s density, playing the true role as a density regulator.

    Sensitizer:hollow glass microspheres can evenly distribute into the emulsion explosive, which formed numerous tiny bubbles with a stable space. Due to the effect of external impulse, the temperature of each microsphere rises rapidly. The burning point of oil is reached as the combustion occurs, resulting in the decomposition of oxidants, so as to achieve the effect of explosion.

    Dimensional Stability:For emulsion explosives, internal media is oversaturated solution with a high density; external media is the oil film with a relatively low density. After adding hollow glass microspheres into the explosives, each spherical surface closes with a number of oil droplets surrounding which hold the spheres afloat, resulting in a stabilized explosive.
