Description
Technical field
The present invention relates to the detection in a kind of gunpowder heating process, harvester, and in particular to one kind can on-line synchronous inspection
Detection, harvester in the gunpowder heating process of the loss of fire detecting medicine heating quality.
Background technology
In current existing technology, mass change of the measurement gunpowder in heating process with the following method is generally adopted：First
Gunpowder is put into baking oven and heated, is taken out gunpowder after a period of time to be heated, and be cooled to after room temperature；Then balance is passed through
Gunpowder quality after measurement is heated, so as to obtain heating the change of forward and backward gunpowder quality.On the other hand, in order to analyze gunpowder
The gas of release/decomposition in heating process；During gunpowder is heated, the gas in baking oven is extracted by air pump, so as to adopt
The gas decomposed in collection Thermal Decomposition of Propellants gasification.
Not only efficiency is low for the method for measuring mass change in gunpowder heating process this at present, and when gunpowder is by baking oven
Take out, cool down, then into balance during measurement, gunpowder high and low temperature alternative, ambient humidity change, when such as removing from air
Influence can be produced to the degree of accuracy of actual data by absorbing moisture etc., caused measurement data to be difficult to authentic and valid reaction gunpowder and added
Mass loss in thermal process.
Further, since during gunpowder is heated, the gas in baking oven is extracted by air pump, to gather Thermal Decomposition of Propellants
The gas decomposed in gasification, will thus form air flow in baking oven；And electronic weighing device（Such as electronic balance）
Weighing precision it is high, and the mass change amount originally very little in gunpowder heating process, the air flow of baking oven will influence whether electricity
