Factors affecting the cooling and bending of Prepainted Galvanized Steel Coil

Prepainted Galvanized Steel Coil's corrosion resistance and heat insulation properties have been widely used in the construction industry. However, sometimes Prepainted Galvanized Steel Coil will bend. The main factors affecting the cooling and bending of Prepainted Galvanized Steel Coil are as follows:

Prepainted Galvanized Steel Coil

1. The high-pressure aerosol nozzle has strong directivity and can complete the partial cooling of Prepainted Galvanized Steel Coil without affecting other parts of Prepainted Galvanized Steel Coil.

2. In the air under normal conditions, the heat transfer coefficients of Prepainted Galvanized Steel Coil are equal to each other, and the wall thickness or shape of the painted Prepainted Galvanized Steel Coil is different. The cooling rate of each part is not uniform, so that the thicker part becomes a hollow tube or the thinner part has a slow cooling rate.

3. For Prepainted Galvanized Steel Coil, the high-pressure ambient air atomizes the water, and increases the surface volume and contour of the water by touching, thereby destroying the vapor film generated by the water and high-temperature structures. The contour is touched and the heat exchange efficiency is improved.

4. When some high-pressure aerosols are used for cooling, since air and water have two heat transfer media, the heat transfer coefficient of water is greater than that of air, so Prepainted Galvanized Steel Coil can increase the heat dissipation rate.
