Abstract

The invention discloses a nonmetal substrate surface coating thickness detecting device. The device comprises a sleeve, an electrical machine fixedly arranged in the top of the sleeve, a pedestal which is arranged in the sleeve and moves vertically driven by the electrical machine, a measuring head fixedly arranged on the lower part of the pedestal, a pressure sensor located between the measuring head and a sensor. The device is used for detecting the nonmetal substrate surface coating thickness, can measure the millimeter-grade coating with a precision of 0.1mm, has the advantages of short detecting period, portable detecting device and reliable detecting result, can achieve efficient and nondestructive detecting for the coating thickness and promote the development of the nonmetal substrate coating thickness detecting technology. Moreover, the invention of the device has low design cost and little art procedure in actual detecting, can reduce the worker's labor intensity and increase detecting safety, and has a good popularization and application value.

Description

technical field [0001] The invention relates to the technical field of coating thickness detection, in particular to a non-metal substrate surface coating thickness detection device and detection method. Background technique [0002] In the process of spraying paint, there will inevitably be coating quality problems such as missed coating, undercoating, accumulation, flow stains, and air bubbles. In addition, equipment exposed to the outdoors will also have quality problems such as coating defects due to environmental influences. At present, domestic research on detection methods for quality problems such as coating defects and flow stains on the surface of non-metallic substrates is quite lacking. By analyzing the current detection methods, a non-metallic substrate surface coating thickness detection device has been developed, which can effectively complete the non-destructive detection of coating thickness and uniformity, and has many advantages such as short detection cy...
