The technological parameter closed, the most economical and the most practical to various novel carriers founding exploratory developments, it is also difficult to meet higher condition and want
Ask.
And invention disclosed patent CN 201473467 has related to a kind of medicine device that is fused and mixed, inventor devises two tank bodies and divides
Not Cun Chu TNT and too peace (PETN), prepare the most serial medical instrument that detonates of ladder by this mixing melting device.This device have man-machine isolation,
The features such as simple operation.But only for TNT series of products, temperature requirement aspect is difficult to meet the requirement that novel carriers is fused and mixed, and
And product category is more single, it is impossible to meet the demand of multiple types small batch research.
Owing to lacking applicable process equipment, manually-operated wrong road is returned again in various novel carriers founding exploratory developments
On.On the one hand, personnel keep Long Term Contact with various poisonous dangerous explosive raw materials, easily cause serious harm function of human body,
Labor intensity weight, stress is big, buries potential safety hazard.On the other hand, founding is affected greatly by anthropic factor, process
Controlling relatively difficult to achieve, product quality fluctuates greatly, and randomness is strong, has deviated from the original intention of scientific research.
It is thus desirable to a kind of small-sized melt-blended device of castexplosive, the use being used for meeting in the research of castexplosive Process Exploration is wanted
