Embodiment 1

[0058] The present embodiment provides a method for detecting the surface roughness of Octogen particles, the method comprising the following steps:

[0059] Step 1, refining the crude Octogen particles so that Octogen particles do not aggregate; the specific refining process is as follows:

[0060] At 25°C, under stirring, Octogen was added to DMSO in five equal parts, the mass ratio between Octogen and DMSO was 55:100, and Octogen was After it was completely dissolved, the temperature was lowered to -10°C, crystals were precipitated, filtered, and dried to obtain the refined Octogen.

[0061] Step 2, determine the number of samples to be tested that need to be drawn, and extract the samples to be tested according to the random number table:

[0062] Determine a sample of Octogen particles with a total of 562, and number each Octogen particle in the sample according to M>N 1 / 3 , where M is the number of samples to be tested, N is the total number of samples of Octojin sampl...

Abstract

The invention discloses a detection method for surface roughness of HMX particles. In the method, through purification of HXM coarse particles, the number of to-be-detected samples which need to be sampled is determined; according to a random numerical table, the to-be-detected samples are sampled and the surface roughness of the to-be-detected samples is measured and then a profile arithmetic mean-deviation mean value and a profile arithmetic mean-deviation indication error are calculated; and at last, report and representation are performed. The detection method for the surface roughness of the HMX particles adopts an optical method for testing and realizes a nondestructive and non-contact test and quantizes the surface roughness of the HMX particles and analyses and evaluates high-quality HMX on the basis.

Description

technical field [0001] The invention belongs to the field of explosives and relates to Octogen, in particular to a method for detecting the surface roughness of Octogen particles. Background technique [0002] For the detection and evaluation of surface roughness, the earliest people used standard samples or samples to make qualitative detection and evaluation of surface roughness through experience (eye view or hand touch). In 1929, German Schmalz first measured the depth of surface microscopic unevenness. In 1936, American Alter successfully developed the first surface roughness profiler for workshops. In 1940, the British Taylor-Hobson Company successfully developed a surface roughness measuring instrument. After that, various countries have successively developed a variety of instruments for measuring surface roughness. The current productized surface roughness measuring instruments can generally be divided into two types: contact type and non-contact type, as shown i...
