Problems solved by technology

[0002] In the early 1950s, explosive spraying technology first appeared in the United States and was put into production. However, due to the technical blockade, the technical party only provided the service of preparing coatings for users, and did not sell the technology and equipment.
The coating area formed by each explosion is limited, the efficiency is low, and the production cost is high
[0004] After searching, there are no relevant reports at home and abroad on the realization of explosive spraying based on explosive energy

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The invention uses explosives as an energy source, and utilizes the shock wave generated by the explosion of the explosives to drive the metal powder to spray on the surface of the metal substrate. The present invention comprises the following components for realizing detonation spraying: detonation mechanism 1, flake charge 2, charge box 3, metal powder 4 for spraying, thin paper sheet 5, support pad 6, metal substrate 7 and wooden backing plate 8 .

[0020] The specific steps of the present invention are as follows: a. place the wooden backing plate horizontally, place the metal substrate on it, and place a support pad on the surface of the metal substrate; b. place the thin paper sheet on the support pad, calculate and weigh according to the coating thickness requirements Spread the metal powder for spraying evenly on the surface of the thin paper sheet; c...

Abstract

The invention discloses an explosion spraying method based on explosive explosion effect, and solves the problem that the energy utilization rate is low, the efficiency is low, the cost is high and large-area sheet metal surface cannot be processed since gas fuel is taken as an energy source in a traditional explosion spraying technology. The device consists of a detonating mechanism (1), sheet explosive (2), an explosive box (3), metal powder for spraying (4), a thin paper sheet (5), a support gasket (6), a metal base plate (7) and a wood base plate (8), and explosion spraying can be realized by triggering the explosive through the detonating mechanism (1). The explosive with large energy density is taken as the energy source, so that the energy utilization rate and production efficiency are improved, the production cost is reduced, and the method is suitable for explosion spraying processing on planes.

Description

technical field [0001] The invention belongs to the technical field of material surface, and mainly relates to a thermal spraying technology, which is mainly applied to the surface treatment of metal plates. Background technique [0002] In the early 1950s, explosive spraying technology first appeared in the United States and was put into production. However, due to the technical blockade, the technical party only provided the service of preparing coatings for users, and did not sell the technology and equipment. By the 1960s, the former Soviet Union began to study explosive spraying technology and made certain breakthroughs. After the disintegration of the Soviet Union in the 1990s, Ukraine and China cooperated in the development of explosive spraying technology, making the technology public. Subsequently, Russia and Ukraine began to sell the technology and equipment to the outside world. Due to the large difference between domestic and foreign technical levels, most of t...
