Abstract

(57) [Abstract] [Objective] The present invention is a production fireworks that produces beautiful flames and sparks with a burning time of 10 minutes or more, which is used as a igniter for a candle used for a candle service at an event such as a wedding. Used as. [Structure] Solid pyrotechnic material composed of ammonium perchlorate as an oxidant, low melting point polyester resin as a combustion improver, iron powder and titanium powder as a spark-generating agent, strontium chloride, and copper powder as a flame colorant into the shape shown in FIG. Fireworks that are made by melting and then cooling and solidifying them in a mold.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is used as a firework for ignition used in place of an ignition tool for igniting a candle during a wedding candle service. It is also possible to install multiple lamps on both sides of the virgin road to ignite and use them to create a gorgeous atmosphere.

[0002]

[Prior art]

 In the past, igniters such as candles and gas lighters have been used for such purposes, but such igniters, which have no tremendous power, are not suitable for producing brilliance.

Further, since the duration of combustion of fireworks up to now is usually less than 1 minute, there is an inconvenience that it is necessary to repeatedly ignite a plurality of fireworks in order to use it for such a purpose. .

[0004]

[Problems to be solved by the device]

 In order to create a gorgeous atmosphere when igniting a candle, during the candle service, obtain fireworks that continue to burn for about 10 minutes. And fireworks that can easily ignite candles. And it is a firework that matches the brilliance of the wedding. Fireworks with little smoke and ash.

[0005]

[Means for Solving the Problems]

 The following means were combined in order to burn for a long time. 1. Use particles of oxidizer as they are in relatively large crystal grains. 2. Use resin such as polyester as a burner. 3. Use a relatively inert metal powder as a spark agent. 4. Lightly coat the sides of the fireworks with non-combustible or flame-retardant paint to prevent the spread of combustion. 5. It has an elongated rod shape.

【Example】

 The following ingredients are blended, kneaded by heating at about 100 degrees Celsius, and pressed into a mold to cool and solidify. For the handle, a mixture of resin and calcium carbonate is placed in a mold and solidified at the same time. Ammonium perchlorate 10g (A part of ammonium nitrate is acceptable) Low melting point polyester resin 3.5g Iron powder 0.5g Nickel powder 0.5g (Cobalt powder is acceptable) Titanium powder 0.2g Copper powder 0.05 to 0.2 grams Strontium chloride 0.5 grams

A water-based paint is thinly and uniformly applied to the solidified fireworks except for the ignited portion, and the fireworks are naturally dried. Since this firework has a burning time of about 2 minutes and 15 seconds per 10 centimeters, it is possible to obtain a burning time of 10 minutes or more at 50 centimeters.

If 1 gram of nickel powder is used without using iron powder, the burning time is about 3 minutes per 10 cm, but the effect of fireworks is somewhat diminished.

Further, if half the amount of ammonium perchlorate is replaced with ammonium nitrate, the burning time will be about 4 minutes per 10 cm. As with the above, the effect of fireworks is diminished, but it has the advantage of halving the amount of hydrogen chloride produced.

[0010]

[Effect of device]

 Since this fireworks has a very long burning time, it can be burnt for the duration of carrying between the tables for the candle service. In addition, the length of the flame and the length of the spark do not become so long, and the direction in which the spark spouts does not spread, and there is only one direction, which has the advantage of reducing the risk of carrying it around. Moreover, since both flames and sparks have the beauty of fireworks, the candle service can be brilliantly colored.
