preparation example Construction

[0017] A method for preparing an electric igniting powder, comprising a step of dipping the electric igniting powder. The step of dipping the electric igniting powder is specifically: according to the mass percentage content of each preparation raw material in the above-mentioned igniting powder, weigh the stacked Nirazide nickel and a binder whose content is 80-110% times that of nickel azide are mixed to obtain the first mixed agent, and the heating element in the electric ignition powder head is dipped with the first mixed agent, and then Perform the first drying treatment on the heating element dipped in the medicine until the water content of the first mixed medicine dipped on the heating element is ≤1%;

[0018] Weighing and mixing potassium picrate and a binder whose content is 80-110% of potassium picrate to obtain a second mixed agent, and using the second mixed agent to dip the heating element after the first drying treatment , and then perform a second drying treatm...

Embodiment 1

[0032] The preparation method of the electric ignition tip of this embodiment sequentially includes the steps of comb tooth stamping, injection molding, shaping, welding bridge wire, dipping in medicine (drying the tip containing the medicine), and butt-welding the lamp. Wherein, the step of dipping the medicine is specifically: in terms of mass percentage, weigh and mix 20% nickel azide nickel and an adhesive whose content is 80% times that of nickel azide, and mix them to obtain the first mixed medicine. The medicine machine dips the heating element in the electric ignition powder head with the first mixed medicine, and then uses the dryer to perform the first drying treatment on the heating element dipped in the medicine until the first heating element dipped on the heating element The water content of the mixed medicament is ≤1%. After the first drying treatment, use the first mixed medicament to dip the heating element for the second time. After the second dipping, continu...

Embodiment 2

[0035] The preparation method of the electric ignition tip of this embodiment sequentially includes the steps of comb tooth stamping, injection molding, shaping, welding bridge wire, dipping in medicine (drying the tip containing the medicine), and butt-welding the lamp. Wherein, the step of dipping the medicine is specifically: in terms of mass percentage, weigh and mix 30% nickel azide nickel and an adhesive whose content is 90% times that of nickel azide, and mix to obtain the first mixed medicine, and use the dipping method to obtain the first mixed medicine. The medicine machine dips the heating element in the electric ignition powder head with the first mixed medicine, and then uses the dryer to perform the first drying treatment on the heating element dipped in the medicine until the first heating element dipped on the heating element The water content of the mixed medicament is ≤1%. After the first drying treatment, use the first mixed medicament to dip the heating elem...

Abstract

Te invention relates to an ignition charge, an electric ignition fuse head and a preparation method of the electric ignition fuse head. The ignition charge provided by the invention is prepared from the following preparation raw materials in percentage by mass: 60 to 80 percent of potassium picrate, 20 to 40 percent of nickel hydrazine azide and the balance of binder, wherein the content of the binder is 80 to 110 percent times the sum of the contents of the potassium picrate and the nickel hydrazine azide. According to the ignition charge, the electric ignition fuse head and the preparation method of the electric ignition fuse head, the advantages that the firing precision and the production safety can be improved are realized.

Description

technical field [0001] The invention relates to the technology of electric ignition components, in particular to an ignition agent, an electric ignition agent tip and a preparation method thereof. Background technique [0002] The electric ignition charge refers to the pyrotechnic element that plays the role of ignition under the action of the heating element. As the core component of the electric detonator, the electric ignition element plays a vital role in the ignition performance of the electric detonator. The electric ignition agent is coated with the electric ignition agent. The current electric ignition agent is usually a mixture of oxidant and combustible agent, which has the problem of poor ignition consistency; there are also trinitroresorphthalate lead single-substance primers as the ignition agent. , although the firing accuracy is high, the safety risk in the production and use process is high. Contents of the invention [0003] The technical problem to be s...
