Embodiment Construction

[0016] The present invention will be further explained below in combination with specific embodiments.

[0017] (1) Surface pretreatment of the heat insulation layer: Clean the surface of the engine heat insulation layer with solvents such as ethyl acetate or acetone to remove small molecular substances attached to the surface of the heat insulation layer, so that the surface is moderately swollen and the heat insulation layer is softened.

[0018] (2) Up-cut milling treatment on the surface of the heat insulation layer: according to the surface treatment requirements, select a milling cutter with a suitable specification. Under the speed of 2200r / min-2800r / min, the milling cutter plans the walking path according to the surface shape, and performs up-cut milling treatment on the surface of the heat insulation layer. . There is a height difference of 0.1mm between the profiler and the milling cutter installed coaxially with the milling cutter, and the height difference is used ...

Abstract

The invention relates to a technological method for treating a heat insulation layer surface of an engine. The technological method comprises the following steps: pretreating the heat insulation layer surface; treating the heat insulation layer surface by up milling; removing dust on the heat insulation layer surface; detecting the roughness of the heat insulation layer surface; and washing the heat insulation layer surface. With the adoption of the technological method, the consistency between the treatment efficiency and quality of the heat insulation layer surface of the engine can be obviously improved; the heat insulation layer surface can be treated in a remote control and isolation manner, thus the damage of dust caused by manually treating the heat insulation layer surface to the physical and mental health of human can be avoided.

Description

technical field [0001] The invention belongs to the technical field of preparation and filling of energetic materials, and in particular relates to a surface treatment method of a thermal insulation layer. Background technique [0002] The effective bonding of various interfaces in the combustion chamber of a solid engine is the key to the structural integrity of the engine. The liner is the transition layer to realize the bonding between the thermal insulation layer and the propellant. If the bonding is not strong and debonding occurs, the engine will The casing is overheated, and the loss of strength makes the engine work invalid. During the production process of the lining layer, the surface of the thermal insulation layer needs to be treated to improve the adsorption force of the lining layer on its surface. The surface treatment process is more important due to the diversity and complexity of the surface state caused by the surface characteristics and processing method...
