Abstract

The invention relates to an energetic material flash point test method and equipment thereof. The method comprises the steps of placing an energetic material to be tested into an inner sample tank, and placing the inner sample tank into an outer sample tank; placing the outer sample tank on a heater; forming a test system through the heater, the sample tanks, a temperature sensor, a flash fire detection ring and a test module jointly, wherein the test module is connected with a control module through a data flat cable. The test system is separated from the control module, and the test system and the control module are separately arranged in different rooms and are separated through an explosion-proof wall. By means of separation operation and reducing the test sample amount, the energetic material flash point test is achieved; the essential security of a test process is improved through separated operation and by reducing the test sample amount, the casualty in a dangerous process is effectively avoided, and the damage to the equipment in the test process is also effectively reduced.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for the flash point of energetic materials. Background technique [0002] Flash point is one of the safety technical indicators of flammable liquid materials, indicating the possibility of burning or explosion, which is of great significance to the safety protection during transportation, storage and use. Some liquid raw materials used for liquid propellants and solid propellants (such as nitrate ester binders) have low boiling points, high volatility, and low flash points, and are more likely to burn or explode in the air. Hydrogen fuels, excipient propellants, etc. also require flash point testing. In view of the explosion hazard of energetic materials, there are no relevant literature reports on the flash point test method, test technology and equipment of energetic materials. The flash point test method of energetic materials is manual face-to-face operation. Large dose testin...
