It is an intuitive method to judge the paint film color and appearance of Customized Shipping Containers, compare the paint film color and appearance with standard color plates and standard samples, observe and evaluate. Before painting, the color of the paint should be checked. After the paint on the test panel dries, its color should be consistent with the color specified in the design. Generally, it is checked against the color standard of the standard color card; the appearance of the paint film should be uniform, dense and glossy.

The flexibility of the sea Customized Shipping Container paint film is measured by bending the test panels on shafts of different diameters, expressed as the diameter of the Z minor axis that does not cause damage to the paint film. The flexibility of the paint film is the comprehensive performance of the paint film attached to the substrate after being bent, and is related to the tensile strength, tensile strength, thickness and adhesion of the paint film.

The water resistance of the paint film of the human body container means that the paint film is immersed in water or boiling water for testing, and it is expressed by the surface change of the paint film after reaching the specified time. Water resistance refers to the performance change of the physical and chemical reactions that occur when the paint film is soaked in water.

When the surface of an object is illuminated by light, the property of light reflecting in a certain direction is gloss. The glossiness of a sample is expressed as a percentage of the ratio of the amount of specularly reflected light from the sample surface to the ratio of the specularly reflected light from the standard sample surface under the same Customized Shipping Containers at a specified angle of incidence.

The heat resistance of the paint film of the human body container refers to the phenomenon that the paint film is heated in a blast oven or a high-temperature furnace, and after reaching the specified temperature and time, reasonable or surface changes occur.

Various coatings for shipping containers have a certain temperature range. Too high or too low temperature will affect the quality of the paint film. In particular, it is necessary to check the heat resistance of the paint used under high temperature conditions to prevent delamination, blistering, cracking, discoloration and other phenomena after construction, which will cause the loss or reduction of the protective performance of the paint film.

The water resistance of the paint film is an important item to test the quality of the paint, because many paints have been used in water, underground or under wet customized shipping containers for a long time. The paint film will peel and wrinkle when exposed to water, indicating that the paint film has no protective properties. Even if it is not used in water for a long time, there will be bubbles, loss of light, discoloration and other phenomena. , or the paint film can return to its original shape after leaving the water, the quality of the paint film will be affected, thereby reducing its protective performance.
