Problems solved by technology

[0002] At present, the nickel hydrazine nitrate primer synthesized by the conventional method always has some fine dusts that cannot be loaded into the normal detonator; and the fine dust of the nickel hydrazine nitrate primer adheres to equipment, walls, floors and other areas, which is brought about by the detonator filling process. security risk
Specifically, the tiny crystals of nickel hydrazine nitrate fly everywhere due to air flow, and will adhere to equipment and tooling due to electrostatic adsorption. There are factors such as friction and impact during the operation of equipment tooling, which will bring safety risks; and The fine nickel hydrazine nitrate agent has poor fluidity, which will lead to uneven charge during the production and filling process, which will also bring product quality risks

Abstract

The invention discloses a water-suspension granulation method of nickel hydrazine nitrate primer, which belongs to the technical field of pyrotechnics. Stir and granulate to obtain spherical polycrystals, and finally sieve to obtain the product; the hydrazine nitrate nickel priming liquid suspension granulation technology of the present invention not only greatly improves the fluidity of the hydrazine nickel nitrate priming charge, but also changes the crystal shape of the product. Reduced chemical dust; the suspension granulation process of nickel hydrazine nitrate priming chemical solution of the present invention not only improves the intrinsic safety of the product, but also reduces the safety risk for subsequent filling due to the reduction of chemical dust, and meets the clean and economical development of pyrotechnic agents , Safe development requirements.

Description

technical field [0001] The invention relates to the technical field of pyrotechnic agents, in particular to a water suspension granulation method for nickel hydrazine nitrate primer. Background technique [0002] At present, the nickel hydrazine nitrate primer synthesized by the conventional method always has some fine dusts that cannot be loaded into the normal detonator; and the fine dust of the nickel hydrazine nitrate primer adheres to equipment, walls, floors and other areas, which is brought about by the detonator filling process. security risk. Specifically, the tiny crystals of nickel hydrazine nitrate fly everywhere due to air flow, and will adhere to equipment and tooling due to electrostatic adsorption. There are factors such as friction and impact during the operation of equipment tooling, which will bring safety risks; and The fine nickel hydrazine nitrate agent has poor fluidity, which will lead to uneven charge during the production and filling process, which...
