Classification of fireworks products

Classification of fireworks products
Products are classified into the following 14 categories according to their structure and the form of movement after being set off.

Fireworks classification chart

1. . Sparklers
   Spray fireworks are products that are mainly sprayed with fire and sparks when they are set off. This kind of products usually use black powder as the launching agent, the fuse ignites the black powder, and the black powder then ignites the coloured beads. At the same time, the black powder burns to produce a large number of gases to the jet hole, which has been lit out of the barrel of the coloured beads launched to a certain height, resulting in a variety of colour and light effects. The production process of this type of fireworks is generally the first clay jet hole, and then install the fuse. The size of the injection hole should be appropriate, large spray is not high, small will explode, generally for the inner diameter of the cylinder shell 1/4 ~ 1/3
2. . Rotating class
   Rotating fireworks refers to the main body of its own rotation but not lift off the product. Rotating products are the use of pyrotechnic burning gas produced by the outward jet to generate thrust, thus rotating around an axis.
3. Lift-off
   Lift-off type fireworks is the main body of the product is directed to lift-off. Lift-off category is the use of power agents (such as black powder) ignited to produce a large number of gases from the bottom of the mud hole spray, by the reaction force and lift-off. Such as rocket fireworks, the key to the production of rockets is to make the power agent layer by layer combustion, if the power agent column pressure is not tight, or cracks in the column, there may be a low explosion.
4. Rotating lift-off category
   Rotating fireworks refers to the products that rotate and lift themselves into the air when they are set off.
5. Spitball
   Spitball fireworks, also known as magic bullet, refers to the same tube from the regular launch of a number of coloured beads, coloured flowers, sound and other effects of the product. Spit bead fireworks structure is grouped, each group puts a layer of effect medicine (such as coloured beads, etc.) and a layer of launching black powder. The upper group and the next group with clay and cardboard away from the next group, usually using a fuse to pass the fire. If the isolation is not good, there will be a rapid succession of fire.
   The simple shell and clay bottom must be firm, and a paper with high tensile strength should be used for the tube shell; the simple shell should be tight and resistant to tension, otherwise it will blow up the tube. If the clay bottom is not firm, it will punch the bottom and hurt people. Installation effect bright beads should pay attention to safety, because the bright beads from the mouth of the tube press down, the drug and the wall of the tube strong friction, high sensibility of the drug may catch fire.
6. Thread incense
   Wire incense class fireworks refers to the use of decorative paper or thin paper tube parcel mounted pyrotechnic drugs, or in the wire bamboo poles, wooden poles or pieces of paper coated with pyrotechnic drugs to form the product.
7. Smoke
   Smoke fireworks refers to the fireworks to produce smoke effects of the main products.
8. Modelling toys
   Modelling toy fireworks refers to the product shell made of a variety of shapes, burning or burning can be imitated after the creation of the image or action; or the appearance of the product is not modelling, but burning or burning can produce a certain image of the product.
9. Friction Fireworks
   Friction fireworks refers to the use of impact, friction and other ways to ignite the main body of the product, such as pulling the gun class, rubbing the gunpowder head class.
10. Small Salute
    Small fireworks are placed on the ground when the fireworks, from the main body of the launch (single tube diameter <76 mm) and burst in the air out of the beads, sound, flute or float and other effects of the product.
11. Shells
    Shell fireworks refers to the projectile from the special launch tool (launch tube diameter > 76 mm) launched into the air can burst out of a variety of light colours, flower patterns into other effects of the product. Shells are generally ignited by the lead, the launch box, the launching drug, the delay lead, the shell, the opening drug, bright beads or effect pieces, rope, etc..
12. Frame fireworks
    Shelf fireworks refers to the position of the fireworks fixed by the frame, the direction of fireworks products
13. Firecrackers
    Firecracker fireworks refers to a single firecracker product or a combination of multiple firecrackers into the product
14. Combination fireworks

Combination of fireworks refers to a combination of multiple single tube, when fired, produce sound, light, colour, floats and other effects of ground fireworks products, divided into a single category of combination of fireworks and multi-class combination of two kinds of fireworks.This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/classification-of-fireworks-products/ This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/classification-of-fireworks-products/
