When the can is punctured, the high-pressure gas inside will be ejected at high speed along the puncture point. This gas spray may not only produce strong noise, but also produce extremely high airflow speed locally, causing harm to people or objects around.

we can see that there is a close relationship between tinplate sheet and tin plating. It can be said that the tin plating process is the basis for tinplate sheet to exert its excellent performance, and tinplate sheet is the main carrier of the tin plating process.

Use sandpaper, wire brush or grinder to rub the surface of tinplate sheet to remove rust attached to the surface. This method is suitable for small areas and shallow rust, but for large areas or severely corroded iron plates, the efficiency is low and it is easy to damage the tin layer on the surface of the iron plate.

According to laboratory measurements and literature data, the thermal conductivity of tinplate sheet is usually between 50-60 W/m·K. The specific value depends on factors such as the composition of the steel base, the thickness of the tin layer, and the manufacturing process.

The primary reason why tinplate sheet loses its gloss is the oxidation reaction on the surface. Although tin is relatively difficult to react with oxygen in the air, under certain conditions, tin will still form an oxide film, causing the surface to lose its gloss.
