Description

Industrial detonator housing and with the detonator of its making

Technical field

The utility model relates to the blast equipment, particularly relates to a kind of industrial detonator housing and with the detonator of its making.

Background technology

Detonator is the higher a kind of product of induced detonation sensitivity in the industrial explosive material, and therefore, its production, packing, transportation and storage process all need higher technical requirements, otherwise will bring potential safety hazard.

At present, the production technique of industrial detonator is: the explosive of packing in metal, inner chamber bottom made of paper or plastic casing, the plumbous stamen of delay powder, with strengthening cap explosive, the plumbous stamen of delay powder are compressed then, and the plumbous stamen of location, card middle part of the side delay powder, the bayonet socket sealing gets final product.There is following unsafe factor in this technology:

1, the detonator with metal shell housing is to adopt mechanical stamping to make, in process of production, because the wearing and tearing of mould are bigger, though product generally can both be in positive and negative worker's difference, but the dipolar product of positive and negative worker's difference, when using at the same time, the difference of precision can make the density and the build-in function assembly of explosive in the pipe labile factor occur, causing the capsular bursting force and the second of millisecond pipe to be measured can not be up to standard, all brings adverse influence for the quality of product and safety in production;

2, the detonator with metal shell housing generally uses mechanical stamping moulding, pickling, rotproofing, copper facing or technology such as zinc-plated in process of production, and this technology is bigger to the pollution of environment, and technology makes cumbersomely, and material price is higher, causes the waste of resource easily;

3, the material hardness of detonator with metal shell housing is higher, in detonator making processes, card waist, bayonet socket kick the beam and do not reach processing requirement, overweight then can causing the capsular built-in part pushed modification and poorly sealed, cause the qualification rate of product to reduce, simultaneously, this bayonet socket technology is concerning the higher detonator of induced detonation sensitivity, having very big potential safety hazard, is one of higher production process of detonator manufacturing enterprise accident rate;

4, detonator shell made of paper, because of material is limit, its intensity and moisture resistance can be relatively poor, simultaneously, also there are 2 comparatively outstanding potential safety hazards in housing made of paper: the one, and the inwall of paper tube housing is rough, when the compacting strengthening cap, easily produce and turn over cap, bulge, danger such as broken pipe, the 2nd, the paper tube housing is twice pressing with when once pressing strengthening cap, because the body precision is not high, the mouth of pipe easily produces burr, and the mouth of pipe infilters floating medicine after the powder charge, when bayonet socket, greatly dangerous, as certain detonator manufacturing enterprise, inferior surplus big minor casualty just took place 10 in this procedure production process, caused personnel's permanent disability and property damage;

5, original plastic detonator shell owing to lack the immature of functional design and use antistatic technology, adopts traditional processing technology aborning substantially, can not embody its due advantage.Therefore, be difficult to extensively promote.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of effective raising industrial detonator production security is provided, and reduces production costs, and beautifies the detonator shell of product;

Another purpose of the present utility model provides the industrial detonator of making of this detonator shell.

The purpose of this utility model is achieved through the following technical solutions:

A kind of industrial detonator housing is characterized in that this housing is by the injection molded barrel of ABS modified plastics that adds static inhibitor, and its bottom is provided with sockets for collecting energy, and sealing part is provided with Baltimore groove;

The short delay detonator that the above-mentioned housing of a kind of usefulness is made, comprise detonator shell and successively pressurization enter intravital one explosive of shell, two road explosives, priming charge, strengthening cap and igniting and seal plastic column, it is characterized in that: described igniting is sealed plastic column and is provided with the localized convex platform that can match with the Baltimore groove on the detonator shell.

The terpolymer that the used ABS modified plastics of the utility model is made up of vinyl cyanide, divinyl, vinylbenzene, it has the machinability of styrenic thermoplastic plastics, the rubber toughness of divinyl, the chemical resistance of vinyl cyanide.

The used HDC-103 plastic static inhibitor of the utility model is a kind of nonionic surface active agent, is white or light yellow particle and powder, and this product can significantly reduce surface of plastic products resistance, makes it reach 10 ^8-9Ω, anti-static high efficiency is lasting, and is suitable with resin compatible, do not influence the processing and the use properties of goods, is dissolved in organic solvents such as ethanol, acetone, chloroform, and its technical indicator comprises: working substance content: 〉=99%

Amine value: 60-80mgKOH/g

Fusing point: 50 ℃ of decomposition temperatures: more than 300 ℃

Toxicity: LD ₅₀This product of＞5000mg/kg (acute toxicity test in mice) can be used as goods such as polyolefins plastics, nylon in add the type static inhibitor, be used for making antistatic macromolecule material, as film, sheet material, container, packing bag (case), the mining two anti-plastics guipures of PE and PP, use and nylon shuttle and such as polypropylene fiber.

The utility model industrial detonator housing and have following technical characterstic with the detonator of its making:

1, the utility model adopts the ABS modified plastics added static inhibitor, and the utilization injection molding process is made housing and bottom integrated, makes it reach the functional requirement of detonating and the production standard of industry.

2, housing of the present utility model and built-in plastics strengthening cap, built-in plastics spacer ferrule and supporting igniting are sealed plastic column and are used simultaneously, finish the improvement of detonator production technique, each build-in function spare all can be produced voluntarily, to reach safety in production, the purpose that reduces cost.

3, the utility model housing inside and outside smooth, toughness is moderate, compares with other original housing, the free-running property that is used as medicine is splendid, after build-in function spare is gone into pipe, matches accurately, does not need machinery card compression set position, makes security of products can obtain whole the lifting.

4, the sealing part of the utility model housing is provided with the twice concave groove and seals twice convex platform on the plastic column with igniting, and is all linked with one another when sealing, and double seal has been guaranteed millisecond pipe second amount accurately.

5, the utility model housing is compared with the detonator with metal shell body, and price reduces by more than 50, and adds removing and the raising of product percent of pass of the card middle part of the side and bayonet socket operation, and its economic benefit is considerable.
