Embodiment 1
[0054] The present embodiment provides a method for detecting the surface roughness of RDX particles, the method comprising the following steps:
[0055] Step 1, refining the crude RDX granules, the specific refining process is as follows:
[0056] At 25°C, under stirring, add RDX into acetone in five equal parts, the mass ratio between RDX and acetone is 40:100, after RDX is completely dissolved, cool down to -10°C, Crystals were precipitated, filtered and dried to obtain refined RDX particles;
[0057] Step 2, determine the sampling length L 取样 =0.1mm, evaluation length L 评定 =0.3mm;
[0058] Step 3, measure the surface roughness of the sample to be tested:

Abstract
The invention discloses a hexogen particle surface roughness measurement method. The hexogen particle surface roughness measurement method comprises the steps that hexogen crude product particles are refined, the sampling length and the evaluation length are determined, the surface roughness of a sample to be measured is measured, an outline arithmetic average deviation average and an outline arithmetic average deviation indication error are calculated, and finally reporting and expression are carried out. According to the hexogen particle surface roughness measurement method, testing is carried out through the optical method, lossless and non-contact testing is achieved, the hexogen particle surface roughness height is quantized, and therefore high-quality hexogen is analyzed and evaluated.
Description
technical field [0001] The invention belongs to the field of explosives, relates to RDX, in particular to a method for detecting the surface roughness of RDX 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. Among them, the cont...
