[0002] AC coated paper is a commonly used inspection tool in metallographic inspections of metal materials in thermal power plants. Traditionally, AC coated paper production relies on manual labor, where liquid AC glue is poured onto the base material and then evenly distributed by hand through shaking or smearing. This method suffers from the following issues: uneven coating thickness, resulting in poor metallographic imaging and inaccurate analysis results; low manual efficiency and high labor intensity make it difficult to meet the demands of inspecting the large number of metal components in thermal power plants; difficulty controlling bubble generation during the coating process, resulting in unstable coating quality; and poor coating thickness consistency, resulting in significant performance variations between batches of coated paper.

[0003] In the existing technology, although there are some mechanical laminating devices that can effectively improve efficiency, most of them have complex structures and high costs, and often have problems with uneven coating thickness. They cannot absorb moisture and stick back, which affects the composite effect and leads to unstable coating quality. Summary of the Invention
