Problems solved by technology

At the same time, different from stainless steel, although the structural material has the characteristics of lighter weight in the same volume, its own anti-oxidation ability is weak, which requires that the surface should be minimized to avoid further oxidation during the cleaning process.

Abstract

The invention provides a water-based cleaning agent for a laser amplification device structural member in an irradiation working environment and a cleaning method of the water-based cleaning agent, and belongs to the technical field of metal part cleaning, the water-based cleaning agent is prepared from the following raw materials by weight: 2 parts of a DBE solvent, 2 parts of 3-methoxy-3-methyl-1-butanol, 5 parts of a nonionic surfactant, 1 part of an emulsifier, and 10 parts of deionized water. Compared with traditional ultrasonic cleaning, the failure time of the ultrasonic cleaning fluid is several times that of traditional pure ultrasonic water-based cleaning fluid, and a large amount of water resources can be saved through the scheme. And compared with traditional ultrasonic cleaning, the working efficiency of the ultrasonic cleaning device is also higher.

Description

technical field [0001] The invention relates to the technical field of cleaning metal parts, in particular to a water-based cleaning agent for structural parts of a laser amplification device in a strong irradiation working environment and a cleaning method thereof. Background technique [0002] The terminal optical components, such as chip amplifier modules, are located in the core link of energy generation in the inertial confinement nuclear fusion Shenguang device, and the entire component is in an intermittent high-irradiation and relatively airtight environment. The modular design allows the amplifier module to be assembled in a class 100 clean room. After sealing, it can be put into the field for further module assembly. Taking the Shenguang II large-scale laser amplifier as an example, neodymium glass is the main gain medium of the laser. [0003] US Patent 4849036 and Chinese Patent CN101976796A both describe the process of soft wrapping of neodymium glass in detail...
