Black Powder
Kayaku Japan produces black powder made
from potassium nitrate, sulfur, and charcoal
by carefully repeating the processes of
mixing, pressurization, and grinding. Black
power thus produced is used for the launch
of fireworks, ensuring ignition of fireworks
especially star, and quarrying of massive
stones, etc. and provides good performance.
Grain black powder
Shape Grain with a diameterof 0.4-1.2mm.
Characteristics / Applications
- Suitable foruse as l ifting charge of fireworks shell.
- Careful kneading together of saltpeter, sulfur, and charcoal, followed by high pressurization and forming, produces a high power.
- Appropriate grain size provides easier handling.
Black powder for toy fireworks
Shape Grainwith a diameterof 0.4-2.0mm.
Characteristics / Applications
- Designed as l ifting charge of toy roman candles.
- The power is weaker than grain black powder.
- Appropriate grainsize provides easier handl ing.
Mealed black powder
Shape Power with a diameter of 0.1mm or less.
Characteristics / Applications
- Suitable foruse for ensuring ignition of star, igniting paper, and other transfer charges.
- Good ignitability.
- Strong force and fast burning velocity.
- A fine and even grain size.
Black powder for hunting
Shape Grain with a diameter of 0.4-1.2mm. The surface has fine gloss with graphite finishing.
Characteristics / Applications
- Suitable for use as hunting gun powder.
- Buming residue is less and bullet velocity is kept at a fixed level.
Blasting powder
Shape Grain with a diameter of 3-7mm. The surface has fine gloss with graphite finishing.
Characteristics / Applications
- Suitable for quarrying of massive stones for example, extraction of masslve granlte.
- Bulk density is 0.85-1 .05, so loading to the blast hole is smooth and the powder is ignited only with fuse.
