Description
Technical field
The invention belongs to commercial explosive technical fields, and in particular to a kind of novel bulk emulsifying explosive and preparation method thereof.
Background technique
Emulsion is a kind of effect by emulsifier, make the droplet of oxidant salts solution be dispersed in containing
Disperse in the oily phase continuous media of the porous masses such as bubble or hollow glass micropearl, the emulsion state for forming a kind of water-in-oil type is fried
Medicine is a new type of industrial explosive to grow up the 1970s.
By packaged form point, emulsion can be divided into packaging emulsion and bulk emulsifying explosive.Packaging emulsification at present is fried
Medicine is all made of plastic film packaging material substantially and gluey medicine body is dressed up the fixed powder stick of shape, by powder stick be fitted into bag, then will in
Bag puts into carton or woven bag, completes packaging emulsion packaging.Package-type emulsion is convenient for handling, transhipment and stores,
It is that can form production unit, circulation unit and the emulsion kind using sale, dealing between unit in the market.This product
By the fixed production line production of factory, have the following problems:
1, safety problem.From the perspective of production technology, the emulsion after sensitization belongs to explosive, powder charge and packaging
Process is more, more complicated will increase the online dose of production line and line personnel, insecurity greatly increase.
2, cost problem.The equipment and construction investment for not talking production line powder charge and packaging, it is existing in terms of concentrating the talk of production cost
The packaging material of emulsion be powder stick film, powder stick bayonet, hot melt adhesive, middle coating, carton, strap etc., which increase creams
Change explosive cost.
3, using problem.Package-type emulsion can only use manual charging, low efficiency；It can not achieve coupling charging, big gun
Hole utilization rate is low；Explosion using effect and the more on-site mixed emulsion of economy are poor.
On-site mixed emulsion is the water oil phase for preparing earth station or emulsion matrix, together with sensitized material and its
His additive is transported to bursting work scene, and a kind of bulk emulsifying explosive of production is blended by site mixed emulsified explosive car,
It is blended again the blast hole projectile filling mode of mechanical filling using scene, there is higher loading rate and matter compared to packaging emulsion
Amount, and without packing cost.
The water phase transported in the tank body of site mixed emulsified explosive car compartment loads in mixture automobile-used emulsion matrix and can pass through joint
It is 5.1 oxidisability that the 8th group of test of state's " Dangerous Goods Transport recommendation-test and standard manual (the 5th revised edition) ", which delimited,
Material management and can be used tank body transport, transit link danger classes lower than packaging emulsion, have certain safety.
On-site mixed emulsion is at bursting work scene in use, scene is blended the pump of risk material involved in process
It send or even closed emulsifier or sensitizing device high speed shear, dispersion and mixing, one loads in mixture cream from the perspective of production technology
Change the explosive production line that explosive truck is equal to a shortening process flow, and bursting work scene is from security protection condition, safety
Management level, safe emergency measure etc. and packaging explosive production line and earth station's gap are larger, although the product after being blended
The mixed loading emulsion explosive truly is just formed after 10~15min, but material is still fallen within after all during being blended
Risk material, once safety interlocking failure, faulty operation etc. still have the possibility that safety accident occurs, the Yongping of Jiangxi in 2013 copper
" 321 " site mixed emulsified explosive car explosion accidents are exactly sadness case to mine.As it can be seen that on-site mixed emulsion bursting work
Scene is blended the safety used and is worth noting.
At home, what on-site mixed explosives truck transported belongs to explosive raw material or semi-finished product, and Policy Conditions only can be by explosion
Work unit production and use cannot sell and circulate as packaging explosive, in addition on-site mixed explosives truck and its breed system
System investment is high, so that the large size blasting engineering project such as the exploitation of on-site mixed explosive large-scale mine, Hydroelectric Project Construction, thus limit existing
The application range of field mixed explosive.Meanwhile this also causes accounting of the domestic on-site mixed explosive in commercial explosive dosage not high,
The requirement of " commercial explosive based on package-type to bulk type and on-site mixed explosive direction from developing " this policy guidance is not met.
Thus, develop one kind that a kind of safety is more preferable, can satisfy the market demand, meets technical progress of industry direction
Novel bulk emulsifying explosive has very important significance.
Summary of the invention
For above-mentioned deficiency present in existing Emulsion Explosive Production application technology, the purpose of the present invention is to provide one kind
Novel bulk emulsifying explosive and preparation method thereof solves existing packaging emulsion and on-site mixed emulsion in safety
Property, economy, service performance or the scope of application etc. there are the problem of.
To achieve the above object, the invention provides the following technical scheme:
A kind of novel bulk emulsifying explosive, including emulsion matrix and sensitized material, which is characterized in that the emulsion matrix by
