Among a wide variety of pyrotechnic products, firecrackers deserve special attention from amateurs. Their appearance is familiar to anyone who has ever encountered pyrotechnic products. Being a classic of the genre, firecrackers are the most popular of all groups of devices for fireworks. In a wide assortment of products on the pyrotechnic market, the corsair firecrackers are especially highly recommended.
What is a product?
Firecrackers "Corsair" are small pyrotechnic devices that are convenient to use at any holiday or celebration. The name “firecracker” comes from the French word ropeter, which means “bursting with a bang.”
What types of firecrackers are there?
Depending on the ignition method and its design, the following types of firecrackers are distinguished:
- Grater. Their ignition is performed using friction on a matchbox. ("Corsair 4").
Wick. For their ignition there is a special fire-conducting cord. ("Corsair 8").
Depending on the reproduced effect, the corsair firecrackers are divided into two types:
- Ordinary. Consist of a cardboard sleeve filled with a pyrotechnic mixture. Simple firecrackers are characterized by a bright flash and a very loud bang. Other effects from the explosion are absent.
- Combined, or compound. The explosion of firecrackers is accompanied, in addition to the standard flash and pop, by additional effects: rotation, whistling, the emission of colorful sparks and smoke. The breaking process is performed in several series. After ignition of the head of the firecracker, the pyrotechnic agent comes into disordered movement. Then, after a piercing whistle, the explosion itself occurs. Those who seek to achieve such effects are advised to purchase corsair-12 firecrackers. The use of this series of products will give brightness to any holiday.
The performance characteristics of large megapetards
Series 12 pyrotechnic products are sold individually in one package:
- The length of the firecracker is 135 mm.
- The diameter of the product is 35 mm.
- The retarder is designed for 8 seconds.
- “Corsair 12” is considered a grater firecracker.
- The effect of use is one powerful light-noise gap.
The composition of the firecracker "Corsair
A paper firecracker sleeve is stuffed with a pyrotechnic mixture that uses powdered magnesium and potassium perchlorate. These chemicals, when burned, are capable of generating high pressure, which is necessary in order to break the cardboard shell. The process ends with a loud bang. In any form of firecrackers, fire is necessary to launch them. If the product is a wick type, then the wick comes into contact with fire. According to the moderator, which is a special chemical composition that gives the exploding time in order to discard the firecracker, the fire is already transferred to the pyrotechnic component of the product itself (magnesium and potassium perchlorate). The photo below the corsair firecracker gives an idea of their general appearance and design features.
The explosion occurs due to the excess pressure formed in the firecracker, which appears as a result of burning of magnesium and potassium. The passage of fire through the moderator takes several seconds. During this time, you need to have time to discard the lit firecracker. The moderator is intended for the safety of consumers of pyrotechnic products.
Making firecrackers at home
Many craftsmen, having free time, often wonder how to make the corsair firecracker yourself?
Before you begin to work, you must acquire the following materials:
- Ballpoint pen with paste.
- Lighter.
- Two pieces of paper. A firecracker and a wick will be made of it in the future.
- Pack of firecrackers "Corsair-1". Due to its low price, this species is very popular among many consumers. One package contains 60 grater firecrackers. They are in the form of sticks 40 mm long.
- Scotch tape.
- Glue PVA.
In order for the manufacturing process of the pyrotechnic product to be intense, it is recommended that all work be performed in stages.
Stages
To make two cases for firecrackers and wicks. This can be done using a ballpoint pen on which two prepared pieces of paper are wound. The diameter of the firecracker can be any. It all depends on the amount of pyrotechnic substance.
Fix the paper wound on the ballpoint pen with PVA glue. The work should be done in such a way that there is a bottom at one end of the firecracker.
Tape the prepared workpiece with tape. This will prevent sticking of the structure.
Fill the created firecracker with pyrotechnic substance. It can be taken from the finished Corsair-1 branded products.
Using paste from a ballpoint pen and paper, make a wick. Work is done in the same way as a firecracker body.
Connect the wick with a makeshift pyrotechnic product. For reliability, it is advisable to use tape.
Nuances in the work
The pyrotechnic substance contained in firecrackers (Corsair-1) is recommended to be kept separately from the fuse, which has the appearance of a pink powder.
During the filling of a makeshift firecracker body, only the substance that is removed from the firecracker should be used. Pink ignition powder can not be poured into the body of homemade firecrackers. It is used only for filling the wick.
The filling of firecrackers with pyrotechnic substance must be performed gradually. After a small amount of powder is poured into the housing, tamping should be performed. This is necessary so that the created firecracker during the explosion does not become a sparkler: when set on fire, it must explode, emitting a loud pop, and not sparkle.
Using pink powder for filling the wick, it is very important to compress everything. The better the igniter is tamped, the longer the wick will burn, which means that the one who will blow up the firecracker has more chances to escape away.
Safety regulations
When using any pyrotechnic means, it is necessary to adhere to safety precautions:
- The explosion radius is up to ten meters. Therefore, the corsair firecrackers should be blown up on an open area specially prepared for this purpose.
- If the firecracker suddenly did not work, you can’t immediately approach it. This can be done after twenty minutes. Most likely, the unexploded product will be defective. Nevertheless, it is recommended to fill it with water.
