Check the color and appearance of the paint film to determine the color and appearance of the container room paint film. The method of visual inspection is to compare the color of the paint film with its appearance with the standard color plate and standard sample. Observation and evaluation. Before coating application, the color of the coating should be checked.
After the coating is dried on the test board, its color should be consistent with the color specified in the design; Compare the color standards of the inspection with those of the standard color card; In terms of the appearance of the paint film, residential container leasing should be uniform, dense, and glossy. The following methods can help you quickly identify the quality of the paint film on the skin of the human container.
Measuring the flexibility of the paint film in a human container involves bending the template onto different diameters of the shaft and indicating the diameter of the small shaft that will not cause damage to the paint film. The flexibility of the coating film is the comprehensive performance of the coating film that adheres to the substrate after bending. It is related to the tensile strength, tensile strength, thickness, and adhesion of the paint film.
The measurement of glossiness of paint films refers to the performance of light reflecting in a certain direction when the surface of an object is illuminated by light, which is called glossiness. The glossiness of the sample is expressed as the percentage of forward and backward light processed at the specified incidence angle on the surface of the living container and the forward and backward light reflected from the standard sample surface of the living container. Produced under the same conditions.
The waterproofing test of the activity room coating refers to the phenomenon of surface changes of the coating film after immersion in water or boiling water for a specified time. Water resistance refers to the changes in the physical and chemical reaction properties of residential container rental when the paint film is immersed in water.
The water resistance of coating films is an important project for detecting the quality of coatings, as many coatings have been used for a long time in water, underground, or humid conditions. If the paint film encounters water, it will peel off and wrinkle, indicating that the paint film has no protective performance. Even if not used in water for a long time, bubbles, loss of light, discoloration, or paint film can still be restored after leaving the water, but it will affect the quality of the paint film, thereby reducing its protective performance.
The heat resistance of the mobile indoor paint film was tested. It refers to the reasonable or surface change phenomenon of the paint film after reaching the specified temperature and time after heating in a drum furnace or high-temperature furnace.
Various types of prefabricated house coatings have a certain temperature range. If the temperature is too high or too low, mobile and movable houses will affect the quality of the paint film. Especially for coatings used under high temperature conditions, attention should be paid to heat resistance. In order to prevent delamination, foaming, cracking, and discoloration after use, and to lose or reduce the protective performance of the film.
