specific Embodiment approach 1

[0020] Specific Embodiment 1: This embodiment is a weakly corrosive removal method for an aluminum-copper composite mandrel prepared by a uranium-containing black cavity, which is specifically completed by the following steps:

[0021] 1. Put the uranium-containing black chamber sample into the sample hole of the sample holder, and fasten the sample holder plate to obtain a sample holder carrying the uranium-containing black chamber sample; the uranium-containing black chamber sample is an aluminum-copper composite mandrel uranium-containing black cavity; 2. Add alkaline solution into the negative pressure demoulding reactor, and when the temperature is constant at 15-60°C, put the sample holder containing the uranium-containing black cavity sample into the negative pressure demoulding reactor, React at a stirring speed of 50-500r / min, a temperature of 15-60°C and an air pressure of 4.0kPa-7.0kPa until no bubbles are generated, and then continue at a stirring speed of 50-500r / m...

specific Embodiment approach 2

[0029] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: the uranium-containing black cavity sample described in step 1 is sequentially composed of aluminum mold core, copper coating, gold protective layer, and uranium conversion layer from inside to outside. and gold support layer. Others are the same as the first embodiment.

[0030] figure 1 It is a schematic diagram of the sample structure of the uranium-containing black chamber described in Embodiment 2. In the figure, a represents the aluminum mold core, b represents the copper coating, c represents the gold protection layer, d represents the uranium conversion layer, and e represents the gold support layer.

specific Embodiment approach 3

[0031] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the aluminum mold core of the uranium-containing black cavity sample carried in the sample rack containing the uranium-containing black cavity sample described in step 2 The volume ratio of mass to alkaline solution (0.6~16) mg:1mL. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a weak corrosivity removing method for an aluminum and copper compound mandrel for preparing a uranium-bearing hohlraum and relates to a demolding method of the uranium-bearing hohlraum. The method disclosed by the invention aims to solve the problem that in the prior art, the uranium-bearing hohlraum of the aluminum and copper compound mandrel cannot be demolded. The weak corrosivity removing method comprises the following steps: I, performing loading to obtain a sample stand containing a uranium-bearing hohlraum sample; II, performing negative pressure demolding to remove an aluminum mold core to obtain the sample stand loading a sample without the aluminum mold core; III, performing cleaning; IV, performing weak corrosivity removal of a copper coating to obtain the sample stand loading a sample without the copper coating; and V, immersing in a complexing agent, cleaning, and demolding the uranium-bearing hohlraum of the aluminum and copper compound mandrel. The method disclosed by the invention has the advantage that the molding success rate reaches 100%. The method disclosed by the invention is primarily applied to demolding the uranium-bearing hohlraum.

Description

technical field [0001] The invention relates to a demoulding method for a uranium-containing black cavity. Background technique [0002] When light nuclei are aggregated into heavy nuclei under extreme conditions, huge heat energy is released instantaneously. If a controlled thermonuclear reaction can be realized, it can provide mankind with inexhaustible clean energy. There are magnetic confinement fusion and inertial confinement fusion (ICF) to achieve controlled thermonuclear fusion reaction. Among them, laser inertial confinement fusion is the most widely studied and fast-growing method, and its driving methods are divided into direct drive and indirect drive. At present, laser fusion at home and abroad is generally based on indirect drive research, because the drive method can reduce the requirements for laser beam uniformity and hydrodynamic instability. The traditional gold black cavity loses energy in the process of converting laser light into X-rays, but adding dep...
