Description

TECHNICAL FIELD

[0001] The utility model relates to the field of paint spraying, especially relates to a temperature and pressure adjusting spraying container system. BACKGROUND

[0002] Three-piece cans are composed of a can bottom, a can body and a can lid. In the manufacture of three-piece cans (such as food or beverage cans), the side seams of the can body are mainly joined by fusion or welding technology; the welds thus formed usually require additional coating protection.

[0003] Welding outer coating mainly consists of resin, curing agent, solvent, lubricant, etc. The lubricant is mainly used to provide smoothness and anti-scratch performance. Due to its physical properties, the density of the lubricant is generally greater than that of the coating. After storage, the lubricant will naturally sink to the bottom, resulting in insufficient lubricant content in the sprayed coating. This in turn causes the outer coating to be scratched when the three-piece can undergoes a necking process, especially a three-necking process. Moreover, when the welding outer coating is used, about 10%-40% of a diluent needs to be added to control the spraying viscosity. Too high a viscosity will result in poor spraying effect, and too low a viscosity will result in a thin coating that cannot withstand high-temperature sterilization. After the diluent is added, the coating also needs to be stirred to be uniform.

[0004] At low ambient temperature, the viscosity of the coating will also increase. In a production environment, if the appropriate temperature cannot be maintained, more diluent needs to be added to control the viscosity for spraying effect, which will also cause the coating thickness to decrease.
