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 drawings.

[0019] The invention uses explosives as energy sources, and uses shock waves generated by the explosives to drive metal powder to spray the surface of the metal substrate. In order to realize explosive spraying, the present invention includes the following components: initiating mechanism 1, flake charge 2, charge box 3, metal powder 4 for spraying, thin cardboard 5, support frame 6, metal base plate 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, place a support frame on one side of the metal substrate, and the support frame is higher than the surface of the metal substrate; b. Place one end of the thin cardboard on the support frame, One end is placed on the metal substrate to form a certain angle with the metal substrate, and the spraying metal powder ...

Abstract

The invention discloses an exploding spraying method for a metal sheet. The method aims to solve the problems that due to the fact that gas fuel is used as an energy source in the traditional exploding spraying technology, the energy utilization rate and efficiency are low, cost is high, and the surface of the large-area metal sheet can not be machined. A detonating mechanism (1), flaky propellant (2), a propellant box (3), metal powder (4) for spraying, a thin paperboard (5), a supporting frame (6), a metal base plate (7) and a wooden base plate (8) are involved in the method. The detonating mechanism triggers explosive materials to achieve exploding spraying. A certain angle is formed between the metal powder (4) for spraying and the metal base plate (7), which is beneficial for improving the quality of coatings. According to the method, the explosive materials large in energy density are used as an energy source, the energy utilization rate is increased, the production efficiency is improved, the production cost is reduced, and the method is suitable for spraying large-area planes in an exploding mode.

Description

Technical field [0001] The invention belongs to the technical field of material surface, mainly relates to a thermal spraying technology, and 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 side only provided users with coating preparation services and did not sell the technology and equipment. By the 1960s, the former Soviet Union began to study explosive spraying technology and achieved certain breakthroughs. After the disintegration of the Soviet Union in the 1990s, Ukraine and China collaborated on the development of explosive spraying technology and made the technology public. Subsequently, Russia and Ukraine began to sell the technology and equipment. Due to the large difference between domestic and foreign technology levels, most of the explosive spraying equipmen...
