Abstract

A colour electrooptical firecracker is composed of sounding part and fuse. Said sounding part contains powdered lead red, copper oxide, Al-Mg alloy and wheat flour, and said fuse is made of potassium nitrate, charcoal powder and sulfur. Said firecracker is mechanically formed by one pass through a cracker machine, and features high productivity, low cost and high safety and reliability.

Description

Special safe and colour electrooptical firecrackers

The present invention relates to new prescription of a kind of firecrackers and working method.

Traditional firecrackers are to adopt explosive chemical substances such as Repone K to form, waste residue is many when setting off, the smoke of gunpowder is dense, smell is pungent, and even more serious is produces, transport, dangerous when setting off, and causes fire and explosion hazard easily, and utilize manual operations, effect is low, cost is high.New by looking into, some novel firecrackers appear in the market, and be to adopt saltpetre, sulphur, aluminium powder as novel electric light big gun 86107448 patents; Safety colour ball flashing firecrackers 89100283 patents adopt red lead powder, cupric oxide, aluminum magnesium alloy, potassium perchlorate, nitrate of baryta, resol, 3-chlorinated benzene to cooperate and form, all have few cigarette, no waste residue, operate, transport, set off safety, but all be to adopt manual operations, effect is low, sound is little when setting off, and poor continuity still can not reach the ideal effect.For the safety that reaches operation, transports, sets off, improve the purpose of effect, the present invention has changed the prescription and the manual operations of traditional firecrackers, adopt mechanize to replace manual operations the compound for preparing, make the firecrackers once shaped, it is fast to reach operation, transports, sets off and be perfectly safe, and improve more than 100 times of effect.

The present invention is prescription and the working method that changes tradition and present novel firecrackers, and the present invention adopts pharmaceutical chemicals such as red lead, cupric oxide, aluminum magnesium alloy, saltpetre, wood charcoal powder, sulphur and flour thereof, cotton yarn, adopts mechanical once shaped to go out product.The firecrackers of producing beat no quick-fried sound in 500 ℃ of temperature or iron hammer, make production, transport, safe ready when setting off.When setting off, product do not have paper scrap, few cigarette, and harmless.

Enforcement of the present invention, special safe and colour electrooptical firecrackers is formed by ringing son and introduction.Ring proportioning red lead powder 49, cupric oxide 20, aluminum magnesium alloy 30, the flour 1 of son, the proportioning saltpetre 50 of introduction, wood charcoal powder 26, sulphur 24.Sound, introduction mixture that proportioning is good respectively stir, sieve, and make then and ring son, introduction pill.Put into the funnel on the firecrackers machine after the sound pill made and introduction pill mixed together in 7: 10 ratio simultaneously, make the yarn that rings on son, introduction and the chessboard of funnel enter the firecrackers mould simultaneously by transmission mechanism, mould varies, be from φ 6--φ 14, die change more according to demand, from the once one-tenth rope form firecrackers that mould comes out, the dipping lacquer packing just becomes product again.Sound reaches 140 decibels when setting off, few cigarette, and no residue, safety improve more than 100 times of effect.

Preparation technology:

1. ring son,, use the 100--120 mesh sieve aluminum magnesium alloy, cupric oxide, red lead powder mixing and stirring.The flour that takes a morsel adds the water accent scattered paste shape of heating, the flour of the three kinds of powder mixs of aluminum magnesium alloy, cupric oxide, red lead powder that sieve and furnishing scattered paste shape is stirred, the compound that stirs is put on the 16--18 order steel sieve granulates, remaining pill is spread a little chemical mixing powder, with sieving rock and roll repeatedly, make it rock and roll till become the garden type, make like this and ring sub-pill.

2. introduction is pulverized saltpetre earlier, uses 100 mesh sieves, in proportion wood charcoal powder, sulphur is added the saltpetre powder, and by stirring, 80 mesh sieves enter 40 mesh sieves again and granulate.

3. after will ringing sub-pill and introduction pill and mixing, fully stir.

4. will ring sub-pill and introduction pill and stir the conical hopper that the firecrackers machine is gone up in the back, pill enters moulding in the firecrackers mould (φ 6--φ 14) simultaneously by the yarn on funnel and the yarn dish, according to own required and modeling footpath.

5. japanning, printing, packing.

Claims

A kind of prescription and manual special safe and colour electrooptical firecrackers that changes traditional firecrackers is to ring son, introduction.Its proportioning of ringing son is aluminum magnesium alloy 30, cupric oxide 20, red lead powder 49, flour 1, introduction proportioning saltpetre 50, wood charcoal powder 25, sulphur 24, flour 1, to ring son, pill made in introduction, stir evenly the firecrackers machine that enters in 7: 10 ratios, once become rope form (φ 6--φ 14) firecrackers by firecrackers machine mould (φ 6--φ 14).
