Industry sets off class and individual sets off class product, has clear stipulaties to various product dose allowance and firing altitude, specialty is seted off
Class is usually used in holding the ceremony of magnificence, and individual sets off class and is used for wedding among the people, funeral, celebrating articles for use.The pyrotechnics structure with firecracker in fact
Similar, its structure all includes black powder and efficacy-enhancing ingredient, and pyrotechnics is filled with to reach preferably performance effect and is largely used to send out
The gunpowder penetrated and exploded.Such as：Standard regulation specialty sets off class combination fireworks display B levels minimum altitude and is not less than 35 meters.Individual's combustion
Put not less than 10 meters outburst effects of class combination C levels fireworks display, and the projectile in these design effects and set off central point laterally away from
It it is 20 meters from C levels, B levels are 30 meters.
The setting of existing firework display launching chamber：
The first kind, it is in outer coil paper cylinder product, is closed in fact from outer barrel bottom by mud base pressure, with showing naturally for outer barrel internal diameter
Shape body is emission cavity, directly inserts inner cylinder in outer tube inner chamber, 1-1.5 millimeters gap is left between outer barrel and inner cylinder and uses paper washer
Sealing is so that outer barrel is isolated with inner cylinder.So virtually add the volume of emission cavity.In addition outer cylinder body is drilled with one or two
It is individual connection both ends inner cylinder fairlead, a large amount of gases are released when lighting transmitting, cause launch nitre dosage it is big, (using 30MM internal diameters as
Single dosage 3.2g-4g of example or so)；And cause not of uniform size can reduce the propulsion effect of propellant powder during lead hole drilling, cause
It is inconsistent and produce a large amount of smog to set off firing altitude, be Jin Liangnian Spring Festival environmental administrations report air quality 2.5PM values most
Great misfortune hand.
Second class, it is molded case fireworks display, though the problem of inner cylinder fairlead loses heart is improved, but still using outer barrel internal diameter as hair
Chamber (by taking 30MM internal diameters as an example, single-shot dose is also not less than 2.2-2.5g) is penetrated, still unresolved dose largely releases after producing gas
The problem of, substantial amounts of energy is consumed, and substantial amounts of smog is produced, it is not reaching to the energy-saving and emission-reduction optimum state of country's promotion.
