Making device of metallographic film-coated AC paper

Abstract

The invention discloses a making device of metallographic film-coated AC paper. The making device comprises a flat bottom groove and an upper cover; the groove bottom of the flat bottom groove is planar; the upper cover is connected with the flat bottom groove in a sealed mode, and forms a sealed first containing space and a second containing space together with the flat bottom groove, wherein thesecond containing space communicates with the first containing space; and the second containing space is provided with a chemical feed pipe capable of being closed. By adopting structures of the upper cover and the flat bottom groove, the two parts can play a certain sealing role, the upper cover serves as the bottom, suitable materials are added according to the size of the second containing space, the chemical feed pipe is closed, and the whole device is shaken periodically till the materials are sufficiently dissolved; a prepared solution is subjected to still standing, the device is reversed to make the flat bottom groove serve as the bottom, the solution enters the first containing space from the second containing space, the device is shaken from side to side to enable the solution to be spread, and then still standing is conducted till the thickness of the solution is uniform; and through opening of the chemical feed pipe, the volatilization speed of acetone is controlled, requirements for an operation technique are avoided, process stability is ensured, and thus the quality of the obtained AC paper is ensured.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on January 24, 2019, with the application number 201910067622.9 and the title of the invention "A device for making metallographically coated AC paper", the entire content of which is incorporated by reference In this application. technical field [0002] The invention relates to the technical field of metallographic inspection, in particular to a metallographic coated AC paper manufacturing device. Background technique [0003] Metallographic inspection is a widely used material inspection method. It may be used in the production, processing and use of materials. On-site metallographic inspection requires a large number of coatings. There are many types of coating materials, among which AC The characteristics of paper lamination speed, good lamination effect and convenient storage are widely used. [0004] The traditional AC coated paper is made of acetone, tr...

Problems solved by technology

[0006] For the solution that has been left for a long time, there may be crystals in it, but it cannot be seen from the appearance of the solution whether there are crystals. After the solution with crystals is spread into thin slices, more crystal particles will appear on the surface, resulting in the failure of the coating. And the volatilization speed is not easy to control
