The commonly used surface treatment methods mainly include degreasing treatment, mechanical treatment, and chemical treatment. The specific process is to use mechanical polishing and sandblasting to remove organic or inorganic reducing substances that are not conducive to bonding on the surface, provide appropriate roughness to the surface, increase effective bonding surface area, reduce solid surface contact angle, improve the wettability of the adhesive on the surface of the adhesive, and improve adhesion performance. Generally, The surface treatment of metal surface rollers can be carried out using wire brushes, grinding machines, or sandpaper to remove loose oxide layers on the surface, or chemical treatment methods=
