40 results about "Flash powder" patented technology

Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly and if confined produces a loud report. It is widely used in theatrical pyrotechnics and fireworks (namely salutes, e.g., cherry bombs, M-80s, firecrackers, and cap gun shots) and was once used for flashes in photography.

Process for dispersing hot-melt adhesive fillers

The invention relates to a method for dispersing hot-melt adhesive filler. The method comprises the following steps that: filler and other components of hot-melt adhesive are evenly mixed by granulation equipment; or part of the filler and other components of the hot-melt adhesive are evenly mixed and granulated by granulation equipment, and then the left over filler is evenly mixed with the granulated mixture. Other components of the hot-melt adhesive comprise main body resin, tackifying resin and a diluent agent; the filler comprises toner, flash powder, calcium carbonate, micro silicon powder, talc powder, white carbon black, light white carbon black, metal nitride, metal oxide and metal nitride or metal oxide; moreover, extruding granulation adopts a single screw extruder or a double screw extruder. The method has the advantages that: the addition of a poisonous and harmful dispersing agent is reduced to protect the environment; the filler is evenly mixed through a physical method, and manufacturing technique is simplified to reduce cost; and because a granular material contains less air volatile matter, the product is not easy to generate air bubbles, thereby ensuring product quality.
