Description

technical field [0001] The invention relates to the field of material processing equipment, more specifically, to an impregnation equipment and an impregnation method. Background technique [0002] The impregnation method is a method commonly used to improve the performance of carbon-based composite materials or ceramic-based composite materials. The metal ions in the impregnation impregnate the material to be treated and penetrate into its inner surface to form a material with superior performance. Among them, the impregnated metal medium generally includes aluminum, copper, titanium and high-temperature alloys. Because impregnation can greatly enhance the performance of materials, impregnation is widely used in aerospace, military and national defense, electronic information, rail transit and other fields. Specifically, when using the impregnation method to process materials, it is often necessary to rely on special impregnation equipment. [0003] At present, due to som...

AI Technical Summary

Problems solved by technology

[0003] At present, due to some limitations in the structural design of the existing impregnation equipment, when using the existing impregnation equipment to impregnate workpieces, the impregnation chamber of the impregnation equipment must be pretreated when each batch of workpieces is processed. (such as vacuuming, heating, pressurizing), then heat the workpiece and the impregnating medium to the specified temperature in the impregnation chamber, then place the workpiece in the impregnation medium for impregnation, and then completely cool the workpiece in the impregnation chamber of the impregnation equipment , and finally take out the cooled workpiece. In this process, the actual time spent on pressure impregnation of the workpiece only accounts for 1 / 6 to 1 / 3 of the entire workpiece impregnation cycle, while a large amount of other time is spent on the pre-heating and In the post-cooling and cooling, it takes a very long time for each batch of workpieces to be impregnated, and the processing speed of the workpieces is very low. When a large number of workpieces need to be processed, it takes a lot of time; in addition, the heating set in the existing impregnation equipment Components and insulation materials need to be heated and cooled again after the treatment of the previous batch of workpieces. At the same time, the impregnation medium set in the impregnation equipment also needs to be heated and cooled again. Such a large amount of heat is directly lost without acting on the impregnation of the workpieces, and the production cost very high
