[0006] (2) The above method is based on the time required for the fluid to completely flow into a plane as the basis for evaluating its fluidity. When the above method is used for melt-cast explosives, it will solidify before it completely flows into a plane, so it cannot be used. time as a criterion

Embodiment 1

[0027] Select explosive B as the sample, pour the slurry into the slurry storage bin and adjust the temperature of the slurry to 90°C, 100°C, and 110°C respectively; Outlet, test the leveling area of ​​the slurry, and the test results are shown in Table 1.

[0028] Table 1B Leveling test of explosives

[0029]

[0030] It can be seen from the test results that the temperature of the contact surface has a significant impact on the leveling of B explosive, and the increase of the temperature of the slurry itself has a certain effect on the improvement of the leveling.

Embodiment 2

[0032] Select Octol explosive as the sample, pour the slurry into the slurry storage bin and adjust the temperature of the slurry to 90°C, 100°C, and 110°C respectively; Outlet, test the leveling area of ​​the slurry, and the test results are shown in Table 2.

[0033] Table 2 Leveling test of Octol explosive

[0034]

[0035] It can be seen from the test results that it is more consistent with the test results of B explosive, the temperature of the contact surface has a significant impact on the leveling of Octol explosive, and the increase of the temperature of the slurry itself also has a certain effect on the improvement of leveling .

Abstract

The invention discloses a fusion cast explosive levelability determinator, which solves the problem that the existing conventional levelability determining method is not applicable to fusion cast explosives. The flowing expansion process of explosive slurry in a material collecting tank (7) is recorded through a high-definition camera (6). Through the processing and the calculation on a video image in the explosive slurry flowing expansion process, the final leveling area of the explosive slurry can be obtained, and can be used as an evaluation index of the fusion cast explosive levelability. The device provided by the invention can be used for testing the leveling areas of the fusion cast explosive slurry with different temperatures on the leveling surface with different temperatures. The fusion cast explosive levelability determinator can be used in the technical field of fusion cast explosive technical study, and has important significance on guiding the fusion cast explosive recipe design and optimization and improving the filling quality of the fusion cast explosives in warheads.

Description

technical field [0001] The invention belongs to the technical field of melting and casting explosive technology research, and relates to a leveling tester for melting and casting explosives. Background technique [0002] Leveling is the ability of the fluid to automatically flow into a plane. By measuring the leveling property of fused-cast explosives, process researchers can predict whether it can fully fill the warhead cavity with complex structures, thereby further guiding the formulation design and development of fused-cast explosives. Charging process design. [0003] At present, the leveling test at home and abroad is mainly used in coatings, inks and other materials, and the testing standards are mainly GB / T1750-1979 paint leveling test method and JB / T3998-1999 paint leveling scratch test method. The test principle of the above method is to smear the tested material on a flat plate, use a scraper to scrape marks on the tested material, and record the time required fo...
