The purpose of measuring dry film thickness is to ensure the quality and performance of the coating. Dry paint film refers to the solid film formed after the paint dries, which is usually used to improve the protection performance and appearance quality of the surface. If the dry film thickness is insufficient, it may not provide adequate protection and be susceptible to abrasion, corrosion and other damage. However, if the thickness of the dry paint film is too thick, it will increase the usage and cost of the paint, and may cause quality problems such as unevenness and cracking of the coating. Therefore, measuring the dry film thickness can ensure that the thickness of the coating meets the requirements, thereby ensuring the protection performance and appearance quality of the painted surface, and it also helps to control the amount of paint used and the cost.
The application of coating Thickness Gauge in the measurement of dry paint film thickness is mainly used to measure the thickness of dry paint film to determine whether the quality and thickness of the coating meet the requirements.
The following are the operation steps of the coating Thickness Gauge in the dry paint film thickness measurement:
Preparation tools: coating Thickness Gauge, standard plate, cleaning cloth, etc.
Prepare the sample: wait for the dry paint film to dry completely before measuring, making sure the sample surface is clean and free of impurities.
Calibrate the instrument: put the coating Thickness Gauge on the standard plate for calibration to ensure accurate measurement of the instrument.
Measure the dry paint film thickness: place the coating Thickness Gauge on the surface of the dry paint film, press the test button, wait for the instrument reading to stabilize and record the measured value.
Repeated measurement: Take multiple measurements on the same area and take the average as the final measurement result.
Record the measurement results: record the measurement results, and perform necessary processing, such as calculating the average thickness of the paint film, judging whether it meets the requirements, etc.
When measuring the thickness of the dry paint film, an appropriate measurement position should be selected to avoid measuring non-coated areas, such as areas with scratches or defects on the paint film surface, so as not to affect the accuracy of the measurement results. At the same time, it is also necessary to operate in accordance with the instructions of the coating Thickness Gauge to ensure the accuracy of the measurement results.
