Abstract

The invention discloses a preparation method of 602 little smoke agent through mechanical mixing. The preparation method comprises the following steps: processing raw materials, selecting raw materials, weighing raw materials, preparing a nitro-cotton adhesive, dry-mixing a tertiary mixture, controlling the grinding time, wet-drying the tertiary mixture, increasing density, granulating, polishing, drying, batching, mixing, and screening qualified particles. The 602 little smoke agent is composed of 78.5 to 81.5% of lead chromate, 14 to 16% of antimony sulfide, 4.5 to 5.5% of potassium perchlorate, and 0.3 to 0.7% of weak cotton additive. The particle size of the agent is in a range of 9 pores / cm (screen underflow) and 19 pores / cm (oversize product). By adjusting the raw materials and dry-mixing and grinding time, the agent can meet the special time requirements of grenade-6 fuze (5.5 to 9 seconds), 83 artificial rainfall fuze (13 to 17 seconds), 07 artificial rainfall fuze (12 to 17 seconds) and the like. The provided agent can be mixed uniformly, the reliability and stability of the agent are high, and the agent is safe to manufacture.

Description

technical field [0001] The invention belongs to the manufacturing technology of multi-component mixed pyrotechnic agents, in particular to a method for mechanically mixing and preparing multi-component micro-smoke powder. Background technique [0002] The production process of 602 micro-smoke medicine is complex and difficult, and the key control technology relies on years of production technology experience. This technology will affect the reliability and stability of the pharmaceutical performance due to the differences in the density, particle size, dry-mixing and grinding time, wet-mixing time, punching time, and operators of each component, resulting in a lot of waste of manpower and material resources. Contents of the invention [0003] The purpose of the present invention is to provide a 602 micro-smoke drug manufacturing process for the disadvantages of the 602 micro-smoke drug production process, which has the following advantages: uniform mixing of medicaments, i...
