Abstract
The invention discloses dedicated gunpowder blocks of a kind of image-text firework dot matrix emitter and preparation method thereof, including gunpowder block, the gunpowder block is set as columnar gunpowder block, and the columnar gunpowder block is made up of fireworks transmitting block and fireworks displaying block of combustion-supporting adhesive sheet bonding；The combustion-supporting adhesive sheet includes adhesive sheet and the adhesive that is arranged on adhesive sheet；The fireworks transmitting block is that the fireworks propellant powder that industry routine fireworks and firecrackers launches mixes and manufactured fireworks transmitting block with ignition performance reinforcing agent and organic bond.The gunpowder block that the present invention is arranged is integrally formed by fireworks transmitting block and fireworks displaying block by combustion-supporting adhesive sheet, not only make fireworks transmitting block and fireworks displaying block clearly demarcated, and it is connected firmly and is not readily separated, and increased adhesive sheet helps to slow down igniting of the fireworks displaying block in transmitting, and the ignition performance reinforcing agent due to adding in gunpowder block and passivator can aid in the igniting of fireworks transmitting block and slows down the burning velocity of fireworks displaying block.
Description
Technical field
The present invention relates to image-text firework field more particularly to a kind of dedicated gunpowder block of image-text firework dot matrix emitter and its systems
Preparation Method.
Background technique
Fireworks are to form color when setting off, pattern, generate acoustics, the product based on visual effect.Originally, cigarette
Flower is to specialize in the noble powerful rich to contend for supremacy the pastime product for struggling against luxurious, has arrived bright, clear, and pyrotechnics manufacturing technology has new development, is increasingly becoming
The gift in red-letter day.Whenever the Spring Festival, the Lantern Festival and other occasions, it will let off fireworks and add to the fun.
The pyrotechnics a multitude of names in China, designs and varieties are quite miscellaneous.Wherein, chrysanthemum type is people's flower pattern the most favorite.Pyrotechnics
After injecting high-altitude, the five colours continued confused photo etching burning before this, after but one by one with opening with the parachute fallen, pyrotechnics overlapping, the night sky
It is beautiful round and round, constitute the pattern of various beauties, become the target that people watch in 15 Lantern Festival of the first month of the lunar year.It is this written in water
Large-scale pyrotechnics, cost are very high.The pyrotechnics that general county town, small towns are put is both grand and restraining, to reach ornamental
Purpose pushes to a new high festive air for target." fiery trees and silver flowers all night with lights turned on " is exactly the real picture of this landscape.However, by
Want high more relative to common fireworks price in the market in the fireworks of picture and text can be formed on high, therefore, before this very
The image-text firework of rare batch is sold, and is typically subscribed by government or enterprise.
Nowadays with the improvement of living standards, the amusement of people requires and consumption eye is also constantly being promoted, fireworks are
A kind of old brand product having continued more than one thousand years, it is lasting, countless celebrating and happy, differentiation thousand, cigarette are added for people
Colored broad categories, have derived many classic products, but with the development of science and technology, original mode also basic development to top,
Difficulty has little progress, has not caught up with the demand of people, and society is upper there is an urgent need to more high-grade, more good-looking, can popularize, that everybody consumes
Novel firework product, in terms of large-scale activity, such as Olympic Games, the countless fireworks group picture of people, with a large amount of personnel and very much
Computer manipulates simultaneously, middle on high to generate footprint figure, but the method needs a large amount of manpower and material resources, and expense is high, and must be repeatedly
Exercise for coordination, old friends are difficult to replicate, it is also difficult to bear such consumption, also have Some Enterprises and individual in image-text firework at present
On done a little trials and research, these people and enterprise have: straight river, straight triumphant, Liuyang City Yu environmental technology fireworks plant, remaining
Training just, Yu Benyou, Liuyang City Dahu Fireworks Displaying Group Co., Ltd, Liuyang City's celebration fireworks culture group it is limited
Company etc. has also applied for patent tens, but its Research idea and technological improvement do not get rid of original development framework yet, does not there is weight
There is a large amount of manufacturings in practical applications, packed and transported, set off, the picture and text various aspects such as simply in quantum jump, and at
This is high, bulky, inconvenient for use, it is difficult to be applied clinically and popularized with popular use, the key for manufacturing image-text firework is picture and text cigarette
Flower lattice structure and the gunpowder block for being assemblied in lattice structure body, the point that the cost of manufacture, unit area include
Number, production efficiency and the reliability emitted simultaneously of lattice point only solve the problems, such as lattice structure and its gunpowder block, figure
Literary fireworks can just accomplish simple and practical in structure, easy to make, suitable high-volume efficiently production, low in cost, be suitble to popular make
With allowing everybody to want to be afforded to use with also just usable.
