Delay composition with long-term healing per second and production method of delay composition

Abstract

The invention discloses a delay composition with long-term healing per second and a production method of the delay composition, and aims at solving the problems that the existing delay composition with long-term healing per second is generally poor in precision and complex in preparation process. The delay composition comprises the following components in percentage by weight: 30%-40% of molybdenum powder, 50%-60% of barium chromate, 5%-15% of potassium perchlorate and 3%-8% of calcium fluoride. The production method of the delay composition has the advantages of a simple production process, a high yield, energy conservation and environmental friendliness, less wastewater produced in the process, and the like. Meanwhile, the delay composition with long-term healing per second disclosed by the invention has the characteristics of a wide delay time range, precise delay, good storage performance and the like, and has a wide application and development prospect in the military and civilian fields at home and abroad.

Description

technical field

[0001] The invention relates to a detonating device, in particular to a detonator detonating device, in particular to a long-second quantity delay drug and a production method thereof. Background technique

[0002] At present, in the blasting process of various mine projects, the long-delay detonator has become an indispensable detonating device. It plays an extremely important role in blasting shock absorption, reducing large block rate, and increasing tunneling speed in mine engineering. As the technical core of the long-delay detonator, the long-second delay drug has a decisive impact on the performance of the long-delay detonator.

[0003] At present, various types of long-duration delay drugs currently available mainly include: tungsten-based, molybdenum-based, and silicon-copper oxide-based delay drugs. The production methods mainly include mechanical wet mixing, co-precipitation, etc., but the prepared long-duration delay drugs Medicines generally ha...
