Detection of color difference on car paint

"Color Difference Detection on Automobile Paint" mainly tells the use of color difference meter to detect the color difference of automobile body spray paint, and mainly describes the detection method, precautions and common problems of automobile color difference detection.

With the continuous development of the national economy, people's living consumption level is also constantly improving, and cars have gradually become one of the necessities for every household to travel. Therefore, the requirements for the appearance and color of automobiles are also constantly improving, and chromatic aberration, as an important factor affecting the appearance of automobiles, is increasingly concerned by automobile manufacturers. Reducing body chromatic aberration has become the research focus of manufacturers.

Regarding the process of automobile production and application, the Colorimeter is mainly used for the control of the automobile body. After the car's body and exterior color parts are painted with color, it is necessary to use a color difference meter to check the color difference.

Use the color difference meter to measure the color difference of the car body, and select several points on the car body for distribution detection, so as to understand the color status of different parts of the car body. Regarding the selection of body detection points, it is necessary to choose a plane as much as possible for the color difference meter to avoid light leakage. To ensure the accuracy of detection.

The application of the Colorimeter in the automotive industry has solved the problem of color difference for manufacturers in many ways. However, in the actual application of the Colorimeter, some improper operation details may affect the accurate reading of the Colorimeter. The following summarizes some Problems that may affect the measurement results of the Colorimeter:

1. The battery power of the Colorimeter will affect the accuracy of the measurement data

The operator needs to ensure that the power of the Colorimeter is used within a reasonable range during use;

2. The accuracy of the Colorimeter itself

After the Colorimeter is used for a period of time, there will be some measurement errors, and the operator needs to calibrate the Colorimeter regularly;

3. The detection direction of the Colorimeter

During the measurement process, the same measurement direction and method need to be fixed to ensure the accuracy of the measurement;

4. The temperature of the body will also affect the accuracy of the detection data

Temperature will have a certain impact on the Colorimeter, so it is necessary to ensure that it is operated under a stable temperature environment during measurement;

5. Detect the influence of pressure

The development of the Colorimeter is mainly formed by the pressure trigger operation. However, the trigger pressure of different operators is different, which will also affect the test data to a certain extent. During the measurement process, the measurement operator should be fixed to avoid bringing unnecessary error;

Points to pay attention to when using the Colorimeter

1) When the battery power of the Colorimeter is less than 30%, please charge or replace the battery in time;

2) Do not measure the car within 4 hours of leaving the baking room or within 4 hours of turning off the engine to avoid detection errors caused by temperature changes;

3) Corresponding to some parts with complex exterior shapes, it is recommended to use the average detection mode to ensure the collection of high-precision data;

4) During the measurement process, fix the testing personnel, and make standardized regulations on the same testing location and direction;

5) If it is found that the precision domestic Colorimeter has test errors and inaccuracies, it should be returned to the factory for repair in time.
