Description
Technical field
The present invention relates to fireworks and firecrackers preparation technical fields, and in particular to a kind of production method of fireworks casing.
Background technique
Fireworks are also known as firework, pyrotechnics, fireworks, are more early invented by Chinese working people, are usually used in grand ceremony or performance
In.Fireworks are in fact similar with the structure of firecracker, and structure all includes black powder and efficacy-enhancing ingredient.For the performance effect reached, flame
The gunpowder for being largely used to emit and explode is filled in fire and display shell, for example, the display shell that a diameter is 20 centimetres exists
After transmitting, to rise to general 200 meters of high-altitude can just explode, and the radius that these are fragmentarily covered can about have 80 meters
Left and right.
In firework structure, the fireworks casing for wrapping up lead, gunpowder and soil is particularly significant, and the structure of fireworks casing is steady
It is qualitative very big for the storage of fireworks and the release safety effects of fireworks, therefore, for the structural soundness of fireworks casing
Suitable promotion be the problem of many fireworks enterprises all pay close attention to.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of producer of more stable safe fireworks casing of structure
Method.
The technical scheme is that providing a kind of production method of fireworks casing, comprising the following steps:
S1, it selects filler: selecting poplar sawdust, a scrap of paper, stalk and chitin fiber silk as shell filler；
S2, screening are rinsed: poplar sawdust, a scrap of paper being screened, stalk is rinsed, by the straw after rinsing well
Stalk is placed under sunlight drying of being sufficiently exposed to the sun；
S3, filler crush: the stalk after a scrap of paper, chitin fiber silk and cleaning-drying is carried out cutting powder respectively
It is broken；
S4, mixing: poplar sawdust and smashed a scrap of paper, chitin fiber silk, stalk are carried out sufficient
It is mixed, adhesive is added in mixing process, mixed shell filler is bonded；
S5, compression molding: the shell filler after mixing bonding is pressed and molded, columnar fireworks casing is pressed into；
S6, drying process: fireworks casing after molding is dried；
S7, internal layer roughening: being placed in the inner wall of tubular fireworks casing using iron wire ball, pulls iron wire ball friction fireworks back and forth
The inner sidewall of shell 5~10 minutes；
S8, outer layer are reinforced: it be coated with adhesive-layer on the lateral wall of fireworks casing, flexible reinforcing mat is bonded on adhesive-layer,
Then the flexible reinforcing mat of package is clinged around the circle of fireworks casing one using plastic film.
Specifically, by making fireworks after selecting poplar sawdust, a scrap of paper, stalk and chitin fiber silk to be pulverized and mixed
Shell, cooperation adhesive are sufficiently mixed so that the cost of manufacture of fireworks casing is lower, and shell mechanism is very firm, during storage
Safety is good.
Further, in step s 4, in the shell filler of mixing, the crushing shredded paper of 30~50 parts by weight is taken
Piece, the poplar sawdusts of 30~45 parts by weight, 8~15 parts by weight crush chitin fiber silk, 15~30 parts by weight
Crushing straw.
Further, the crushing a scrap of paper, the poplar sawdust of 35 parts by weight, 12 weights of 35 parts by weight are taken in shell filler
Measure the crushing straw for crushing chitin fiber silk, 20 parts by weight of number.
Further, before step S6 dries fireworks casing, using in moisture tester measurement fireworks casing
Water content,
When water content is less than 7%, paper is placed in 35~45 degree of environment and is preheated 10~15 minutes, then to paper into
The drying of row high temperature, drying condition continue 20~22 minutes at 55~65 degree；
When water content is in 7%~12%, paper is placed in 40~50 degree of environment and is preheated 18~25 minutes, then is right
Paper carries out high temperature drying, and drying condition continues 40~50 minutes at 65~70 degree；
When water content is greater than 12%, paper is placed in 48~54 degree of environment and is preheated 15~20 minutes, then to paper
High temperature drying is carried out, drying condition continues 70~90 minutes at 70~80 degree；
The fireworks casing dried finally is placed in natural cooling under cool environment.
Further, in step s 8, the flexible reinforcing mat is degreasing cotton gauze.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
The present invention provides a kind of production methods of fireworks casing, comprising the following steps:
S1, it selects filler: selecting poplar sawdust, a scrap of paper, stalk and chitin fiber silk as shell filler；
S2, screening are rinsed: poplar sawdust, a scrap of paper being screened, stalk is rinsed, by the straw after rinsing well
Stalk is placed under sunlight drying of being sufficiently exposed to the sun；
S3, filler crush: the stalk after a scrap of paper, chitin fiber silk and cleaning-drying is carried out cutting powder respectively
It is broken；
S4, mixing: poplar sawdust and smashed a scrap of paper, chitin fiber silk, stalk are carried out sufficient
It is mixed, adhesive is added in mixing process, mixed shell filler is bonded；
S5, compression molding: the shell filler after mixing bonding is pressed and molded, columnar fireworks casing is pressed into；
S6, drying process: fireworks casing after molding is dried；
S7, internal layer roughening: being placed in the inner wall of tubular fireworks casing using iron wire ball, pulls iron wire ball friction fireworks back and forth
The inner sidewall of shell 5~10 minutes；
S8, outer layer are reinforced: it be coated with adhesive-layer on the lateral wall of fireworks casing, flexible reinforcing mat is bonded on adhesive-layer,
