Abstract
The invention relates to the formulation of a high-energy safety silent blasting agent, which is prepared from magnesite powder 45-55 parts, aluminum powder 220-280 parts, copper oxide 540-660 parts, ferric oxide 85-105 parts, powdered activated carbon 4-6 parts through mixing. The preparing process of the formulation comprises, mixing magnesite powder and aluminum powder, grinding and passing through 1000 mesh sieve, then mixing copper oxide, ferric oxide and powdered activated carbon with a wood mill and fully mixing, finally stirring and mixing the two kinds of powder. The prepared blasting agent can improve disrupting efficiency and realize environmental protection.
Description
Technical field
The present invention relates to formula of high energy safety microsound blasting agent and technology, relate to a kind of safety of dynamite component, the blasting agent prescription and technology of environmental protection of not containing specifically.
Technical background
At present, the blasting agent on the market often contains dynamite component, and when destroying concrete and rock, noise is big, dust is many, vibrations are violent, and safety coefficient is little, should not be used near dwelling house or densely populated place.And owing to contain dynamite component, unstable properties is dangerous in storage, the use, even causes serious demolition accident.So use and very inconvenient when take care of.For preventing that demolition accident from taking place, must make each link of blasting operation that the careful management of special messenger's specialty is all arranged.Therefore, the manning requirement has been proposed in the enterprise that carries out blasting operation.In addition, owing to very easily produce environmental pollution due to composition and the blasting effect, be unfavorable for environmental protection.Along with restriction and the environmental protection requirement that explosive uses, the blasting agent that uses easy, safe, shockproof, the no slungshot of whole process, no dust, noiselessness, no poison gas to pollute more and more is subjected to people's favor.
Summary of the invention
The object of the present invention is to provide a kind of use, preservation, easy, safe, shockproof, the no slungshot of transportation, no dust, noiselessness, free of contamination formula of high energy safety microsound blasting agent and technology.
The object of the present invention is achieved like this:
Formula of high energy safety microsound blasting agent is characterized in that pressing row weight part proportioning and mixes:
Magnesium powder 45-55 part aluminium powder 220-280 part
Cupric oxide 540-660 part ferric oxide 85-105 part
Powdered carbon 4-6 part.
High energy safety microsound blasting agent technology is characterized in that following these steps to preparation:
1, earlier magnesium powder, aluminium powder mixed grinding are crossed 1000 mesh sieves;
2, cupric oxide, ferric oxide, powdered carbon mix, with ligneous barreling mill, and thorough mixing;
Two kinds of mixed powders that 3, will grind stir and mix and promptly get high energy safety microsound blasting agent.
Described high energy safety microsound blasting agent outward appearance is the Dark grey pressed powder;
Using method is to prepare jewel hole on the object of removing with boring bar tool earlier, then toward the hole
The middle blasting agent of filling inserts fuse, and energising is ignited.
The present invention compared with prior art, convenience, safety, low, shockproof, the no slungshot of cost, no dust, noiselessness, no poison gas pollute, in the big gun hole, produce the tensile strength that huge bulging force (3000kg/cm square) is far longer than various rocks (50-250kg/cm square) and concrete (30-50kg/cm square), various rocks and concrete moment are burst.Safe distance is a 10-20 rice, and quiet distance is a 30-50 rice.Under area of can concentrate personnel, buildings is intensive or the special conditions such as indoor materials such as concrete, reinforced concret and rock are implemented explosion.Simultaneously, this product does not belong to danger rule product, not controlled by security administration department.Can consign by ordinary goods (air transport, land transportation, water transport, train transportation etc. all can, not limited by various forms of transport).Improved working efficiency and environmental.

Embodiment 4
The performance test of the foregoing description 1 gained high energy safety microsound blasting agent:
Outward appearance: Dark grey pressed powder;
Bursting force test: a: ignite in air with fuse, moment is produced temperature 3500 degree; B: ignite in borehole with fuse, moment produces 3000 kilograms per centimeter
2
Using method: with boring bar tool jewel hole on the object of preparing dismounting, fill blasting agent then in the hole earlier, insert fuse, energising is ignited;
Observe blasting result: object is broken rapidly, does not produce shockwave, the fragment that disperses do not occur;
The explosion sound test: the sound, vibrations slightly promptly be can't hear outward for 30 meters;
Safe distance: 10 meters;
The safety index test: match, cigarette, lighter, ignitron, detonator, nichrome wire, safety fuse and heating 1000 degree high temperature iron staffs insert and all it can not be ignited;
