Background technology
Fireworks and firecrackers belongs to inflammable explosive article, and the ultimate challenge faced from producing to consuming is exactly safety problem, either
The person of setting off or manufacturing enterprise, if not produced or being seted off according to pertinent regulations, security incident will be likely to result in
Occur.In the past few years, fireworks and crackers safety production accident frequently occurs, Guangxi Pubei, Hebei Xinji, and Yichun of Heilongjiang Province etc. is successive
Occur especially great fireworks and firecrackers explosion accident, wherein Yichun of Heilongjiang Province is most representative and typicalness, personnel caused by accident
Injures and deaths and economic loss are heavy.
Folks of china just has the custom of " enabling firecracker " from ancient times, i.e., when the new year arrives, every household opens the door the
Something is exactly firecracker of setting off fireworks, and is cleaned away the dirt and the old of the past year and usher in the new in Pi crack noise of firecrackers.After noise of firecrackers, it is broken it is red completely, be referred to as " full
Hall is red ".Completely it is broken it is red be exactly fireworks and firecrackers after explosion by fried fragmented cylinder.
The raw material of traditional fireworks cylinder are mainly paper, and when fireworks are ignited or after explosion, its cylinder also can be therewith
Situation about lighting happens occasionally, and the cylinder and cylinder fragment that ignite are scattered everywhere, and in case of combustible easily triggers fire, safety is hidden
Trouble is well imagined.Further, since fireworks and firecrackers itself determined the characteristics of inflammable and explosive its must stored dry, if air is wet
Spend big or imprudence to be soaked, fireworks and firecrackers just can not reuse, and turn into a pile waste product, not only waste of resource, and right
Consumer and the enterprise producer will be an economic losses.
