[0013] Embodiment 1: making of red shiny beads. Including the following steps:

[0014] In the first step, the inner core drug and the outer coating drug required for preparing the bright pearl, by weight,

[0015] Inner core medicine: 30% magnesium powder, 27% strontium sulfate, 40% ammonium perchlorate, 3% binder;

[0016] Outer package medicine: 25% of potassium nitrate, 15% of magnesium aluminum alloy powder, 52% of military nitrate powder, 5% of phenolic resin, and 3% of binder; said binder is such as water-soluble starch (superglue powder).

[0017] The components are mixed uniformly according to the general method.

[0018] In the second step, by weight ratio, potassium dichromate is added in the inner core medicine, and the addition is 5% of the inner core medicine; by weight ratio, potassium dichromate is added in the outer coating medicine, The addition amount is 8% of the outer package medicine;

[0019] The third step is to use water as the solvent in the drum ...

Embodiment 2

[0021] In the fifth step, after the wrapping of the outer-coated medicine is completed, the wet bright beads are taken out and dried to obtain the finished bright beads. Embodiment 2: making blue light bright beads. Including the following steps:

Abstract

The invention discloses a bright pearl manufacturing method. By means of the bright pearl manufacturing method, two granulating and drying processes are not needed, one-time forming is achieved in a facility for granulating, and finished product bright pearls can be obtained through one-time drying. An effective isolation effect is finally achieved through adding of potassium dichromate, interinfiltration between inner core medicine and outer package medicine under the action of hydrosolvent is eliminated, and the burning performance of bright pearl medicine is stabilized. Meanwhile, based on the dissolution common-ion effect of potassium dichromate and other oxides, the drying speed of the manufactured bright pearls is accelerated, the bright pearl structure is more dense, and larger impact force can be borne. The stability of the bright pearls is good based on the surface passivation action on live wave metal by the potassium dichromate, quality is stable, and the quality consistency of the bright pearls is good. In this way, the bright pearl quality and stability are effectively improved, the firing effect is guaranteed, the production process is simplified, the production cycle is shortened, potential safety hazards are reduced, and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a bright bead for fireworks and firecrackers. Background technique [0002] In the production of fireworks and firecrackers, the particles formed by granulation of pyrotechnic drugs are called bright beads. The lighting effects of the beads are various. Generally, it includes two parts: the inner core drug that produces the corresponding effect and the outer coating drug that mainly plays the role of ignition. The outer coating medicine is generally pyrotechnic powder, and the mixed-effect bright pearl outer coating medicine includes pyrotechnic powder and other effect medicines at the same time. For certain types of fireworks pearls, such as red light effect pearls, green light effect pearls, blue light effect pearls, flickering effect pearls, ring pearls, etc., the core medicine must be granulated with water as a solvent to produce relatively strong Good firing effect. However, if water is also used as a solvent for the o...
